22.10.0 - 2022-09-27

Commits

Highlights

Added a context menu option to extract the shortest path between two nodes as a new tree. Select the source node and open the context menu by right-clicking on another node in the same tree. #6423
Add setting for gamma correction for color and grayscale layers in the left sidebar. #6439
Added a context menu option to separate an agglomerate skeleton using Min-Cut. Activate the Proofreading tool, select the source node and open the context menu by right-clicking on the target node which you would like to separate through Min-Cut. #6361
The color of a segments can now be changed in the segments tab. Rightclick a segment in the list and select "Change Color" to open a color picker. #6372
Sharing links are shortened by default. Within the sharing modal, this shortening behavior can be disabled. #6461
The largestSegmentId is no longer a required property for segmentation layers. It is still recommended to set the property, since the generation of new segment IDs is blocked during volume annotation. However, annotating with manually set IDs is still possible. This change simplifies the import of datasets into webKnossos. #6414

Added

Zarr-based remote dataset import now also works for public AWS S3 endpoints with no credentials. #6421
Added a "clear" button to reset skeletons/meshes after successful mergers/split. #6459
The proofreading tool now supports merging and splitting (via min-cut) agglomerates by rightclicking a segment (and not a node). Note that there still has to be an active node so that both partners of the operation are defined. #6464
Added workflow reporting and logging features for Voxelytics into webKnossos. If activated, the workflows can be accessed from the Administration > Voxelytics menu item. #6416 #6460
Added possibility to read N5 datasets. #6466
Added "shift + w" shortcut to cycle backwards through annotation tools. #6493

Changed

Selecting a node with the proofreading tool won't have any side effects anymore. Previous versions could load additional agglomerate skeletons in certain scenarios which could be confusing. #6477
Removed optional "resolution" parameter from /datasets/:organizationName/:dataSetName/layers/:dataLayerName/data route. Use mag instead. #6479
Changed how volumes containing no data are stored. Now the selection of magnifications is correctly exported and imported. #6481
The "Restore Older Version" list is now paginated which improves performance for in case many versions exist. #6483

Fixed

Fixed sharing button for users who are currently visiting a dataset or annotation which was shared with them. #6438
Fixed the duplicate function for annotations with an editable mapping (a.k.a. supervoxel proofreading) layer. #6446
Fixed isosurface loading for volume annotations with mappings. #6458
Fixed importing of remote datastore (e.g., zarr) when datastore is set up separately. #6462
Fixed a crash which could happen when using the "Automatically clip histogram" feature in certain scenarios. #6433
Fixed loading agglomeate skeletons for agglomerate ids larger than 2^31. #6472
Fixed bug which could lead to conflict-warnings even though there weren't any. #6477
Fixed that one could not change the color of a segment or tree in Firefox. #6488
Fixed validation of layer selection when trying to start globalization of floodfills. #6497
Fixed filtering for public datasets in dataset table. #6496

22.09.0 - 2022-08-25

Commits

Highlights

Added an "extrude segment" feature which is similar to the old "copy from previous slice" feature. The segment interpolation and the new segment extrusion feature are both available via the toolbar (see the dropdown icon which was added to the old interpolation button). #6370
The owner of an annotation can allow other users, who may see the annotation, to also edit it. Note that parallel writes are not supported and would lead to conflicts. #6236
Added support for ad-hoc meshing for volume annotation layers with fallback segmentations. #6369
Added support for 64-bit segmentations (uint64). Note that the actual support only covers IDs up to 2^53 - 1 (matches the JavaScript number type). Also note that JSON mappings are only compatible with segment ids that only use the lower 32 bits. #6317
WebKnossos now remembers the tool that was active in between disabling and enabling the segmentation layer. #6362
The Add Dataset view now hosts an Add Zarr Dataset tab to explore, configure and import remote Zarr datasets. #6335
Added a UI to manage Zarr links for an annotation so that the annotation can be streamed to third-party tools. This change also includes new backend API routes for using the (private) zarr links to annotations as well as creating them. #6367

Added

Segmentation layers which were not previously editable now show an (un)lock icon button which shortcuts to the Add Volume Layer modal with the layer being preselected. #6330
The NML file in volume annotation download now includes segment metadata like names and anchor positions. #6347
Added new backend API route for requesting all publications. Those publications can now have also attached annotations. #6315
Added a "duplicate" button for annotations. #6386
Added new filter options for the dataset list api at api/datasets: organizationName: String, onlyMyOrganization: Boolean, uploaderId: String #6377

Changed

webKnossos uses WebGL 2 instead of WebGL 1 now. In case your browser/hardware does not support this, webKnossos will alert you and you need to upgrade your system. #6350
The sharing modal now automatically saves changes of the sharing options. #6314
The Layers tab now displays an Add Skeleton Annotation Layer button with which volume-only annotations can be converted to hybrid annotations. #6330
The Zarr directory listings no longer include the current directory “.”. 6359
The default name for volume annotation layers with fallback segmentations is now set to the name of their fallback segmentation layer, no longer “Volume”. #6373
The “reload data” button for dataset and annotation layers is now only shown to users who have administrative permissions for the dataset (because the button clears server caches and file handles). #6380
Requests for missing chunks in zarr datasets now return status code 404 instead of 200 with an empty response. #6381
Dataset layer thumbnails now by default show the center of the intersection of all layer bounding boxes, so all layer thumbnails show the same region. 6411

Fixed

Fixed a regression where the mapping activation confirmation dialog was never shown. #6346
Fixed an error if multiple proofreading actions were performed in rapid succession. If webKnossos is busy, inputs to the viewports are disabled from now on. #6325
Fixed that ad-hoc meshing would terminate early for large segments. #6352
Fixed a bug where the largestSegmentId of zarr segmentation layers was not propagated from the datasource-properties.json, which broke annotating based on these layers. #6363
Fixed a bug where uploads of wkw datasets with numerical-only layer names would fail. #6382
Public datasets of other organizations are no longer listed during task creation. #6377
Tightened organization isolation security for dataset uploads. #6378
Fixed a bug with undo/redo and volume interpolation/extrusion. #6403
Fixed a regression which caused that uint16 and uint8 segmentations could not be rendered. #6406
Fixed a bug which prevented keyboard shortcuts from taking affect after expanding/collapsing the sidebar panels using the button icons.#6410
Fixed a bug with the clip histogram button to prevent it from showing a loading spinner forever in some cases. #6407
Fixed an issue whereby a warning toast would be triggered every time the 3D viewport is put into fullscreen mode. #6412

Removed

The Annotation Type label was removed from the info tab. #6330
Removed the possibility to load data from foreign webKnossos datastores. Use Zarr streaming instead. #6392

22.08.0 - 2022-07-20

Commits

Highlights

Merged the "Shared Annotations" tab into the "Annotations" tab in the user's dashboard. If annotations are shared with you, you can see them in your dashboard. The table can be filtered by owner if you prefer to see only your own annotations. #6230
Add new backend API routes for working with annotations without having to provide a 'type' argument. Note that these support stored annotations (Task and Explorational), but do not work for CompoundTask/CompoundProject/CompoundTaskType annotations. For the latter, please use the original route variants with explicit type. #6285

Added

Added a warning for invalid volume layer names. The layer names must now be unique among all layers in an annotation and must not contain url encoded special characters. #6289
Added optional mappingName parameter to requestRawCuboid datastore route, which allows to directly apply a specified mapping in the backend. #6311
Added option to use X-Auth-Token header instead of query parameter in every datastore and tracingstore route. #6312

Changed

Changed the name of the volume annotation layer in tasks to be "Volume" instead of "Volume Layer". #6321
Dataset managers are now allowed to change dataset team permissions for all teams they are a member of. #6336

Fixed

Fixed that zooming out for datasets with very large scale was not possible until the coarsest level. #6304

22.07.0 - 2022-06-28

Commits

Highlights

Added a image data download speed indicator to the statusbar. On hover a tooltip is shown that show the total amount of downloaded shard data. #6269
Provide a UI to download/export a dataset in view-mode. The UI explains how to access the data with the python library. #6283

Added

Added a warning for when the resolution in the XY viewport on z=1-downsampled datasets becomes too low, explaining the problem and how to mitigate it. #6255
Added the possibility to view and download older versions of read-only annotations. #6274
Added a proofreading tool which can be used to edit agglomerate mappings. After activating an agglomerate mapping the proofreading tool can be selected. While the tool is active, agglomerates can be clicked to load their agglomerate skeletons. Use the context menu to delete or create edges for those agglomerate skeletons to split or merge agglomerates. The changes will immediately reflect in the segmentation and meshes. #6195

Changed

For the api routes that return annotation info objects, the user field was renamed to owner. User still exists as an alias, but will be removed in a future release. #6250
Slimmed the URLs for annotations by removing Explorational and Task. The old URLs are still supported, but will be redirected to the new format. #6208
When creating a task from a base annotation, the starting position/rotation and bounding box as specified during task creation are now used and overwrite the ones from the original base annotation. #6249
Increased maximum interpolation depth from 8 to 100. #6292

Fixed

Fixed that bounding boxes were deletable in read-only tracings although the delete button was disabled. #6273
Fixed that (old) sharing links with tokens did not work, because the token was removed during a redirection. #6281

22.06.1 - 2022-06-16

Commits

Fixed

Fixed that the context menu broke webKnossos when opening it in dataset-view-mode while no segmentation layer was visible. #6259
Fixed benign error toast when viewing a public annotation without being logged in. #6271

22.06.0 - 2022-05-27

Commits

Highlights

Added a volume interpolation feature. When triggering the interpolation, the current segment id is interpolated between the current slice and the slice which was annotated last. Note that the feature is forbidden for tasks by default, but can be enabled/recommended. The feature can be used via a button in the toolbar or via the shortcut V. #6162 and #6235
Removed the feature to copy a segment from the previous/next slice with the V shortcut. Use the new volume interpolation feature instead (also bound to V and available via the toolbar). #6235
Selecting "Download" from the annotation actions now opens a new modal, which lets the user select data for download, start TIFF export jobs or copy code snippets to get started quickly with the webKonossos Python Client. #6171
Added a long-running job that materializes annotations as datasets. It merges volume annotations with their base segmentation layer and it applies “merger mode” annotations, allowing to agglomerate segments. Access this feature from the layers sidebar. When merger mode is active, an additional button is shown in the tool bar. #6086

Added

Added a batching mechanism to the task creation via NML to support uploading more than 100 NMLs at a time. #6216
Added support to stream zarr files using the corresponding zarr spec. #6144
Added support to stream volume annotations as a zarr data set. #6203
Added segmentation layers to the functionality catching the case that more layers are active that the hardware allows. This prevents rendering issue with more than one segmentation layer and multiple color layers. #6211
Adding a New Volume Layer via the left border tab now gives the option to restrict resolutions for the new layer. #6229
Added Route to get OME-NGFF Headers for a data layer (.zattrs file) following the corresponding spec. #6226
Added Route to get OME-NGFF Headers for Volume annotation. #6242

Changed

When creating a new annotation with a volume layer (without fallback) for a dataset which has an existing segmentation layer, the original segmentation layer is still listed (and viewable) in the left sidebar. Earlier versions simply hid the original segmentation layer. #6186
Changing the visibility of a layer within an annotation does not change the visibility of the layer when viewing the corresponding dataset. #6186
While viewing tracings in read-only mode, the options to manipulate the tracing are now disabled. This leads to less confusion as previously the input was silently discarded. #6140.
Changed default of dynamicSpaceDirection property to false to avoid confusion. #6162
Changed the internal protocol for requesting image data. The zoomStep parameter has been replaced by mag. This increases the datastore API version to 2.0 #6159
In annotation list in dashboard, replaced the non-standard word “Trace” by “Open”. #6191
Tiff export via webknossos-worker is now allowed for all datasets that a (logged-in) user can see, no longer only for datasets of their own organization. #6219

Fixed

Fixed a bug in the task creation, where creation for some tasks with initial volume data would fail. #6178
Fixed a rendering bug which could cause an incorrect magnification to be rendered in rare scenarios. #6029
Fixed a bug which could cause a segmentation layer's "ID mapping" dropdown to disappear. #6215
Fixed the 3d viewport for datasets with low voxel resolution by making the camera far clipping adaptive to the dataset extent. #6221.
Fixed a non-critical error message when resizing the browser window while webKnossos loaded a dataset or annotation. #6247

22.05.1 - 2022-04-29

Commits

Fixed

Fixed applying recommended settings when starting a task which provides recommended settings. #6175

Removed

Removed the option to download sample-datasets. To explore webKnossos, use the public sample datasets on webknossos.org. #6151

Breaking Changes

22.05.0 - 2022-04-26

Commits

Highlights

The mouse cursor now changes appearance to indicate the currently selected annotation tool #6132

Changed

Various changes to the Dataset table in the dashboard #6131:
Renamed "Allowed Teams" column to "Access Permissions".
Add filter functionality to "Access Permissions" column to filter for public datasets.
Removed isActive and isPublic columns to save screen space.
Changed data layer entries to display layer names instead of categories, e.g. "color" --> "axons".
Moved the list of "user with access to the selected dataset" from the dashboard to the respective dataset's settings (Sharing Tab). #6166
Sped up initial requests for remote zarr dataset by using asynchronous caching. #6165

Fixed

Fixed a bug that led to an error when drag-'n'-dropping an empty volume annotation in the dataset view. #6116
Fixed rare callstack overflow when annotating large areas. #6076
Fixed the "Copy Slice" shortcut (v and shift + v) in resolutions other than the most detailed one. #6130
Fixed a bug where dataset tags with spaces would be automatically wrapped in quotes. #6159
Fixed a bug where during dataset upload, un-sorted anisotropic mags in the datasource-properties.json could lead to errors. #6167

Removed

Removed the functionality to unlink the fallback layer from an existing segmentation layer. Either create an annotation without fallback layer or from within an annotation with a fallback layer, create a new volume layer, instead. #6146

Breaking Changes

22.04.0 - 2022-03-22

Commits

Highlights

The visible meshes are now included in the link copied from the "Share" modal or the "Share" button next to the dataset position. They are automatically loaded for users that open the shared link. #5993
Added a new "Connectome Tab" which can be used to explore connectomes by visualizing neurites and their synaptic connections. Connectome files need to be placed in a connectomes folder inside of the respective segmentation layer. It is possible to craft links that automatically load specific agglomerates and their synapses when openend. For more information refer to https://docs.webknossos.org/webknossos/sharing.html#sharing-link-format. #5894

Added

Added a context-menu option when right-clicking on skeleton trees to hide/show all other trees but the selected one. Great for inspecting a single tree in isolation. Identical to keyboard shortcut "2". #6102
Added support for reading Zarr image data. #6019

Changed

The maximum brush size now depends on the available magnifications. Consequentially, one can use a larger brush size when the magnifications of a volume layer are restricted. #6066
Improved stability and speed of volume annotations when annotating large areas. #6055
In dataset upload, linking layers of existing datasets is no longer restricted to public datasets. #6097
Deactivating users with currently active tasks is no longer allowed. #6099

Fixed

Fixed a bug that led to crashing the layer settings once the icon for the downsample modal was clicked. #6058
Fixed a bug where toggling between not archived and archived annotations in the "My Annotation" of the dashboard led to inconsistent states and duplicates of annotations. #6058
Fixed a bug where deactivated users would still be listed as allowed to access the datasets of their team. #6070
Fixed occasionally "disappearing" data. #6055
Fixed a bug where remote-origin headers were omitted in error case. #6098
Increased the timeouts for some internal operations like downsampling volume annotations. #6103
Fixed a bug where there was a suggested change in the datasource-config.json was shown for resolution 1 instead of [1,1,1] or vice-versa. #6104

Removed

The previously disabled Import Skeleton Button has been removed. The functionality is available via the context menu for datasets with active ID mappings. #6073
Removes experimental (and hidden) automatic brushing feature. Consequentially, the corresponding feature flag autoBrushReadyDatasets is not used, anymore. #6107

Breaking Changes

22.03.0 - 2022-02-21

Commits

Highlights

Added experimental min-cut feature to split a segment in a volume annotation with two seeds. #5885
Added a button next to the histogram which adapts the contrast and brightness to the currently visible data. #5961
Viewport scale bars are now dynamically adjusted to display sensible values. #5418

Added

Added the option to make a segment's ID active via the right-click context menu in the segments list. #5935
Running uploads can now be cancelled. #5958
Annotations with multiple volume layers can now be uploaded. (Note that merging multiple annotations with multiple volume layers each is not supported.) #6028
Decrease volume annotation download latency by using a different compression level. #6036

Changed

Upgraded webpack build tool to v5 and all other webpack related dependencies to their latest version. Enabled persistent caching which speeds up server restarts during development as well as production builds. #5969
Improved stability when quickly volume-annotating large structures. #6000
The front-end API labelVoxels returns a promise now which resolves as soon as the label operation was carried out. #5955
webKnossos no longer tries to reach a save state where all updates are sent to the backend to be in sync with the frontend when the save is triggered by a timeout. #5999
When changing which layers are visible in an annotation, this setting is persisted in the annotation, so when you share it, viewers will see the same visibility configuration. #5967
Downloading public annotations is now also allowed without being authenticated. #6001
Downloaded volume annotation layers no longer produce zero-byte zipfiles but rather a valid header-only zip file with no contents. #6022
Changed a number of API routes from GET to POST to avoid unwanted side effects. #6023
Removed unused datastore route checkInbox (use checkInboxBlocking instead). #6023
Migrated to Google Analytics 4. #6031

Fixed

Fixed volume-related bugs which could corrupt the volume data in certain scenarios. #5955
Fixed the placeholder resolution computation for anisotropic layers with missing base resolutions. #5983
Fixed a bug where ad-hoc meshes were computed for a mapping, although it was disabled. #5982
Fixed a bug where volume annotation downloads would sometimes contain truncated zips. #6009
Fixed a bug where downloaded multi-layer volume annotations would have the wrong data.zip filenames. #6028
Fixed a bug which could cause an error message to appear when saving. #6052

22.02.0 - 2022-01-24

Commits

Highlights

Added the possibility to add additional volume layers to an existing annotation via the left sidebar. #5881

Added

Added a warning when navigating away from editing the dataset's properties without having saved. #5948
Tiff exports are now served from the datastore module to prepare for remote datastores with webknossos-worker. #5942
Added the organization id to the auth token page and organization page. #5965
Added the possibility to cancel running webknossos-worker jobs. #5946
Partially executed floodfills can now be finished by starting a worker job from the bounding box tab (requires a webKnossos instance where jobs are set up). #5905

Changed

Improved the UI for automatic suggestions to the datasource properties when editing a dataset. #5948

Fixed

Fixed bug where volume data downloads would sometimes produce invalid zips due to a race condition. #5926
Fixed a bug which caused that the keyboard delay wasn't respected properly when rapidly pressing a key. #5947
Fixed that navigating away from uploading a dataset properly warns the user that there is unsaved state. #5948
Fixed a bug where an organization would be created for an already existing email address. #5949
Fixed a bug where the paths of uploaded files were not checked correctly. #5950
Fixed that the used datastore could not be changed in the UI when uploading a dataset. #5952
Fixed the context menu positioning at the bottom and right edges of the screen. #5976

Removed

Breaking Changes

22.01.0 - 2022-01-04

Commits

Highlights

Added tagging support for datasets. #5832

Added

Dataset upload back-end now supports linking layers of existing public datasets. #5863
Activate the correct mapping before loading pre-computed meshes if the corresponding mesh file contains that information. #5859

Fixed

Fixed a bug where dataset uploads that contained files larger than 2 GB failed. #5889
Fixed that dataset uploads did not survive back-end restarts. #5831
Fixed a bug where NMLs with unconnected trees and nested tree groups could not be uploaded due to wrong tree group IDs. #5893
Fixed a security vulnerability by upgrading log4j to newest version. #5900

Breaking Change

When using the front-end API, functions that accept a layer name, such as api.data.getDataValue, won't interpret the name "segmentation" as the current volume tracing if it exists. Instead, "segmentation" can only be used if the current dataset has a layer which is named "segmentation". If you want to interact with the volume tracing layer, use api.data.getVolumeTracingLayerIds() instead. Also see api.data.getSegmentationLayerNames and api.data.getVisibleSegmentationLayer. #5771
The datastore server routes /datasets/reserveUpload and /datasets/finishUpload now expect the additional field layersToLink, which should be an empty list by default. [#5863](https://github.com/scalableminds/webknossos/pull/5863

21.11.2 - 2021-12-21

Commits

Fixed

Fixed a security vulnerability by upgrading log4j to newest version (2.17.0). #5913

21.11.1 - 2021-12-16

Commits

Fixed

Fixed a security vulnerability by upgrading log4j to newest version (2.15.0). #5900

21.11.0 - 2021-11-30

Commits

Highlights

Added a new bounding box tool that allows resizing and creating bounding boxes more easily. Additionally, the context menu now contains options to modify the bounding box close to the clicked position. #5767

Changed

The docker setup has been restructured, which requires changes to existing docker-compose setups. See the migration guide for details. #5843
By default, if data is missing in one magnification, higher magnifications are used for rendering. This setting can be controlled via the left sidebar under "Render Missing Data Black". #5862
Made the w shortcut to cycle through the tools non-looping. #5865
The communication with webknossos-worker for long-running jobs no longer uses flower/celery, but instead webKnossos itself assigns jobs to polling workers. #5834

Fixed

Fixed a bug that the displayed value range of a histogram of a color layer wasn't applied until the slider was dragged a bit. #5853
Fixed a bug where admins could not share annotations with teams they were not explicitly a member of. #5845

Removed

Removed 1 shortcut which allowed to cycle through the tools but only if some of the tools were active. Use w instead. #5865

21.10.0 - 2021-11-08

Commits

Highlights

A new "Segments" tab was added which replaces the old "Meshes" tab. The tab renders a list of segments within a volume annotation for the visible segmentation layer. The list "grows" while creating an annotation or browsing a dataset. For example, selecting an existing segment or drawing with a new segment id will both ensure that the segment is listed. Via right-click, meshes can be loaded for a selected segment. The mesh will be added as child to the segment. #5696
Enhanced the volume fill tool to so that it operates beyond the dimensions of the current viewport. Additionally, the fill tool can also be changed to perform in 3D instead of 2D. #5733
The active mapping is now included in the link copied from the "Share" modal or the new "Share" button next to the dataset position. It is automatically activated for users that open the shared link. #5738

Added

Added the possibility to load the skeletons of specific agglomerates from an agglomerate file when opening a tracing by including a mapping and agglomerate ids in the URL hash. See the docs for further information. #5738
Added a skeleton sandbox mode where a dataset can be opened and all skeleton tracing capabilities are available. However, by default changes are not saved. At any point, users can decide to copy the current state to their account. The sandbox can be accessed at <webknossos_host>/datasets/<organization>/<dataset>/sandbox/skeleton. In the combination with the new agglomerate skeleton loading feature this can be used to craft links that open webknossos with an activated mapping and specific agglomerates loaded on-demand. #5738
For ad-hoc mesh computation and for mesh precomputation, the user can now select which quality the mesh should have (i.e., via selecting which magnification should be used). #5696
The context menu in the data viewport also allows to compute an ad-hoc mesh for the selected segment. #5696

Changed

Improved the movement behavior when using shortcuts to navigate along the 3rd dimension. Instead of clamping the sub-voxel position to .0 or .99 on the initial movement, the keyboard delay is adapted dynamically to avoid too fast movements. This change especially improves the move behavior when quickly changing the direction backwards/forwards. #5801

Fixed

Fixed two volume tracing related bugs which could occur when using undo with a slow internet connection or when volume-annotating more than 5000 buckets (32**3 vx) in one session. #5728
Jobs status is no longer polled if jobs are not enabled, avoiding backend logging spam #5761
Fixed a bug that windows user could not open the context menu as it instantly closed after opening. #5756.
Fixed a bug where the health check of public datasets failed if no cookie/token was supplied. #5768.
Fixed a bug where retried save requests could lead to a 409 CONFLICT error if the first request was already handled by the back-end. #5779.
Fixed a bug where volume annotations could not be saved under certain circumstances (if "Render Missing Data Black" was disabled and a data bucket was annotated for the first time). #5783
Fixed a bug which made the ad-hoc mesh loading abort too early. #5696
Fixed that viewports turned black when zoomed in very much. #5797
Fixed the bucket loading order in the YZ and XZ viewports. Data in these viewports will be rendered faster than before. #5798
Fixed that collapsing/expanding the sidebars did not work for touchscreens. #5825
Fixed a bug where projects could not be listed if the tracing time got too large. #5823

21.09.0 - 2021-10-01

Commits

Highlights

Added shortcuts K and L for toggling the left and right sidebars. #5709
Added support for datasets that have multiple segmentation layers. Note that only one segmentation layer can be rendered at a time, currently. #5683

Added

Added a rudimentary version of openAPI docs for some routes. Available at /swagger.json. #5693

Changed

By default, if data is missing in one magnification, higher magnifications are used for rendering. This setting can be controlled via the left sidebar under "Render Missing Data Black". #5703
Refactor the format of the URL hash/fragment to alternatively use JSON. Old links will continue to work. #5730

Fixed

Fixed a bug where existing tasktypes with recommended configurations still had a property that is no longer valid. #5707
Fixed that segment IDs could not be copied to the clipboard. #5709
Fixed a bug where volume annotation version restore skipped buckets that were not yet touched in the version to be restored. #5717
Fixed a rendering bug showing non-existent or wrongly-colored edges that sometimes occurred after deleting edges, nodes, or trees. #5724
Fixed an error during viewport maximization in flight mode. Also, fixed a crash during minimization of the 3D-View for datasets with lots of magnifications. #5746

21.08.0 - 2021-08-26

Commits

Highlights

Added the possibility to restrict the volume resolutions when creating explorative annotations. Use this to annotate larger structures without creating tons of high-res data. #5645
Most recent dataset conversions are shown in dashboard (if the webKnossos instance supports processing jobs). #5597
Added UI to infer nuclei for webknossos instances that support jobs (e.g., webknossos.org). #5669

Added

Fixed a bug where non-existing resolutions could be selected for wk-worker-based meshfile computations #5631
Added new mesh-related functions to the front-end API: getAvailableMeshFiles, getActiveMeshFile, setActiveMeshFile, loadPrecomputedMesh, computeMeshOnDemand, setMeshVisibility, removeMesh. #5634
Added a route to call new webknossos-worker job for nuclei inferral. #5626
Added shortcut information to the context menu. Some shortcuts that are only available for the classic controls are only shown when the classic controls are active. #5677
For webknossos.org, a "What's New" notification was added to the navbar. #5665
Added tooltips for all elements of the Settings tab in the left sidebar. #5673

Changed

Improved context menu for interactions with segmentation data that wasn't loaded completely, yet. #5637
Any feature connected to computational jobs like precomputing a meshfile is now disabled for non local hosted datasets. #5663
Clicking outside of the context menu closes it without performing any other action (e.g., previously, a node could be created when clicking outside of the context menu, when the skeleton tool was active). Also, a repeated rightclick doesn't open the context menu again. #5658
When the option "Rendering missing data black" is turned of, the fallback data is now shown up to a zoom difference of 3. Previously it was 1. #5674

Fixed

Fixed that active segment and node id were not shown in status bar in a non-hybrid annotation. #5638
Fixed that setting an intensity range of a color layer to 0 via the histogram slider led to no data being rendered at all. #5676
Fixed that "Compute Mesh File" button was enabled in scenarios where it should not be supported (e.g., when no segmentation layer exists). #5648
Fixed a bug where an authentication error was shown when viewing the meshes tab while not logged in. #5647
Fixed that segment id 0 was always shown even when fallback data of the segmentation layer was visible and hovered with the mouse. #5674
Fixed that nodes could only be selected via the context menu when an annotation was opened in read-only mode. Shift-Click will now work, too (and if "Classic Controls" are disabled, a simple left click will work, too). #5661
Fixed that the copy buttons in the context menu did not work properly. #5658
Fixed that the position of the mouse displayed in the statusbar was not updated properly when navigating via the keyboard. #5670
Fixed that creating a new node in merger mode did always turn off the "Hide unmapped segments" setting. #5668
Fixed that undo in volume annotations might overwrite the backend data on not loaded magnifications with zeros. #5608
Fixed a bug where volume annotation downloads were occasionally cancelled with “Connection reset by peer” error. #5660
Fixed that the ad-hoc mesh computation was disabled for volume annotations. #5689

Breaking Change

The interface of the cross-origin API changed. The initialization message is no longer an object with a message property of "api ready", but instead an object with a type property of "init". Additionally, if an API call finishes, a return message of type "ack" is sent. If the original API call contained a messageId property, the return message will contain the same messageId to allow to match the return message. If the API call is misformatted, a return message of type "err" is sent, containing an error message in the message property.

21.07.0 - 2021-07-21

Commits

Highlights

Several improvements and changes have been implemented for the toolbar, sidebar and status bar. See the full changelog for all details (grouped under #5384). Alternatively, read the corresponding blog post. The most important changes are:
The toolbar now contains dedicated tools for moving, editing skeletons and erasing volume data.
Right click opens a context menu for all tools, unless "Classic Mode" is enabled in the Settings tab (left sidebar).
The two tabs in the left sidebar "Annotation" and "Dataset" were renamed and restructured to "Layers" and "Settings". Some elements were also moved to other areas, such as the toolbar (e.g., the merger mode) or to dedicated tabs in the right sidebar (e.g., bounding boxes).
The status bar contains additional elements for (editable) information, such as the active tree id (previously positioned in the left sidebar).
Added compatibility with newer JREs, tested with 8, 11 and 14. #5558

Added

Added the possibility for admins to set long-running jobs to a “manually repaired” state. #5530
The toolbar contains two additional tools: #5384
one for the skeleton mode (similar to the existing move tool).
one for erasing volume data (similar to right-dragging with the previous brush/trace tool)
Added colored icons to the status entries in the job list. #5572
Back-end side analytics are now sent to events-relay.webknossos.org by default. You can opt out by setting backendAnalytics.uri to empty in your config. 5607

Changed

Improve error logging for unhandled rejections. #5575
Improved dragging behavior of trees/groups in the tree tab. #5573
"Center new Nodes" option was renamed to "Auto-center Nodes" and changed to also influence the centering-behavior when deleting a node. #5538
The displayed webKnossos version now omits the parent release name for intermediate builds. #5565
The following changes belong to #5384:
The move tool is only capable of performing movements (its skeleton-functionalities were moved to a dedicated skeleton tool).
(Unless classic mode is enabled:) Right-click opens a context-sensitive menu by default with various actions, such as creating an edge between two nodes. Consequently, important actions which were done via right click previously were changed:
- In the skeleton tool, left click can be used to create, select and move nodes. Also, mere dragging (without hovering a node) moves the active position (similar to the move tool).
- In the trace/brush tool, erasure cannot be performed with right click, anymore. Instead, CTRL + Shift + Left Click works for erasing. Alternatively, selecting the dedicated erase tool also works.
The two tabs in the left sidebar "Annotation" and "Dataset" were renamed and restructured to "Layers" and "Settings".
- "Layers" contains the layers which were previously visible in "Dataset".
- Also, "Layers" contains a dedicated Skeleton layer which handles skeleton-specific settings (e.g., clipping distance).
- "Merger Mode" and "Soma Clicking" were moved to the toolbar (visible when the skeleton tool is selected).
- “Brush Size” was moved to the toolbar (visible when brush or brush-eraser is selected)
- "Controls" and "Viewport options" (previously under "Annotation") and "Data Rendering" (previously under "Dataset") were moved to "Settings".
- The "Bounding Boxes" section in "Annotation" tab was moved to an own tab to the right sidebar.
- The "Mapping" setting was moved to the segmentation layer in the left sidebar.
The status bar contains additional elements for (editable) information, such as the active tree id (previously positioned in the left sidebar).
In some UI elements, text was replaced by icons. An explaining tooltip can be shown by hovering.
The health check at api/health does not longer include checking data/health and tracings/health if the respective local modules are enabled. Consider monitoring those routes separately. #5601
Improved the progress display for dataset uploads. 5616

Fixed

Fixed that a disabled "Center new Nodes" option didn't work correctly in merger mode. #5538
Fixed a bug where dataset uploads of zips with just one file inside failed. #5534
Fixed a benign error message when a dataset without a segmentation layer was opened in view mode or with a skeleton-only annotation. #5583
Fixed crashing tree tab which could happen when dragging a node and then switching directly to another tab (e.g., comments) and then back again. #5573
Fixed a bug that the selection of nodes in the skeleton tool was possible for nodes far behind the position and thus prevented creating new nodes. #5624
Fixed that the UI allowed mutating trees in the tree tab (dragging/creating/deleting trees and groups) in read-only tracings. #5573
Fixed "Create a new tree group for this file" setting in front-end import when a group id of 0 was used in the NML. #5573
Fixed a bug that caused a distortion when moving or zooming in the maximized 3d viewport. #5550
Fixed a bug that prevented focusing the login fields when being prompted to login after trying to view a dataset without being logged in.#5521
Fixed a bug that prevented the modal to export data of a bounding box to tiff files to open up. #5624
Fixed that the 3d view content disappeared permanently if the 3d view was resized to not be visible. #5588
Fixed a bug where nested tree groups were messed up during NML upload if “Create a new tree group for this file.“ is selected. #5596

Removed

The following changes belong to #5384:
Removed "Highlight hovered cells" setting (highlight on hover will always be done).
The "Volume" tab was removed. The "Mapping" setting was moved to the segmentation layer in the left sidebar. The "segment id" table was removed, as the status bar also contains the information about the hovered cell id.

Commits

Highlights

Added the possibility to load precomputed meshes from a meshfile via the meshes tab or context menu. #5345
Added the option to hide the plane borders and crosshairs in the 3D viewport. Also, this setting was moved from the "Other" section of the user settings to the 3D viewport. Additionally, added a setting to hide the dataset bounding box in the 3D view. #5440

Added

Added an icon to the info tab of a tracing that links to the dataset settings. It's located next to the dataset name. #5462
Upgraded several dependencies including Play framework to 2.8, yielding performance and security improvements. #5515

Changed

Active nodes and trees are now highlighted with a background color in the comments tab. #5461

Fixed

Fixed that the row selection in the user table wasn't properly preserved when filtering the table and (un)selecting rows. #5486
Fixed a bug where histograms generation failed for tiny datasets. #5458
Fixed a bug where NMLs with huge tree IDs uploaded via back-end produced broken annotations. #5484
Fixed a bug that led to various possible inconsistencies in the dataset settings in the datasource tab, when the inferred datasource properties suggested by the backend were accepted by the user. #5492
Fixed a bug where the upload of multiple NMLs failed if some of them have an organization attribute and others don’t. #5483
Fixed a bug in the application of agglomerate files where the cumsum.json was not used correctly. #5499
Improve loading of precomputed meshes and fix some issues (e.g., deleting a mesh which was still being loaded) which could produce an invalid state. #5519
Fixed an innocuous error toast when opening the dataset import view. #5526
Fixed that creating/editing a volume task type didn't allow submitting the form. #5532

Removed

Removed the button to load or refresh the isosurface of the centered cell from the 3D view. Instead, this action can be triggered from the "Meshes" tab. #5440

21.05.1 - 2021-05-05

Commits

Highlights

Added a dark theme for webKnossos. #5407

Changed

The deployment configuration of webKnossos was cleaned up. If you host your own webKnossos instance, be sure to update your config according to the migration guide. #5208

Fixed

Fixed a bug where users could see long-running jobs listing of other users #5435
Fixed a rendering bug which occurred when the initial layout had a hidden 3D viewport. #5429
Fixed an incorrect initial camera rotation in the 3D viewport and an incorrect initial zoom value. #5453
Fixed a bug where the task search showed duplicates if a user had multiple instances of a task (as made possible by the transfer functionality). #5456
Fixed a bug where showing active users of a project, and transferring their tasks was broken. #5456

21.05.0 - 2021-04-22

Commits

Highlights

The layout of the tracing view was revamped. Most notably, the layout now has two well-behaved sidebars (left and right) which can be collapsed and expanded while the remaining space is used for the main data view. Additionally, a status bar was added which shows important information, such as the currently rendered magnification and useful mouse controls. #5279
Added a screenshot of the 3D view when using the screenshot functionality in the tracing view. #5324

Added

The names of Task Types and Projects no longer need to be globally unique, instead only within their respective organization. #5334
Upgraded UI library antd to version 4, creating a slightly more modern look and behavior of many UI elements. #5350
Tiff export jobs of volume annotations now show the link back to the annotation in the jobs list. #5378

In the new REST API version 4, projects are no longer referenced by name, but instead by id. #5334

Fixed

Fixed a bug where some values in the project list were displayed incorrectly after pausing/unpausing the project. #5339
Fixed that editing a task type would always re-add the default values to the recommended configuration (if enabled). #5341
Fixed a bug where tasks created from existing volume annotations that did not have a specified bounding box were broken. #5362
Fixed broken search functionality in select components. #5394
Fixed a bug which could cause corrupted trees when CTRL+Rightclick was used in an empty tree. #5385

Fixed artifacts in screenshots near the dataset border. #5324
Fixed a bug where the page would scroll up unexpectedly when showing various confirm modals. #5371
Fixed a bug where user changes (email, activation) would show as successful even if they actually failed. #5392
Fixed a bug where dataset uploads were sent to the wrong datastore, and failed. #5404

21.04.0 - 2021-03-22

Commits

Highlights

Added the possibility to upload datasets without zipping them first. #5137
Added CTRL+Scroll for zooming, which enables pinch-to-zoom on some trackpads. #5224

Added

The time spent on a project is now displayed in the project list. #5209
Added the possibility to export binary data as tiff (if long-runnings jobs are enabled). #5195
Added a link to dataset view mode from annotation mode info tab. #5262

Fixed

Fixed a regression in the task search which could lead to a frontend crash. #5267
Fixed a rendering bug in oblique mode. #5289
Fixed a bug where uploading NMLs from dashboard via file picker was inaccessible. #5308

Breaking Change

The front-end API methods measurePathLengthBetweenNodes, measureAllTrees and measureTreeLength were changed to return a tuple containing the distance in nm and in vx (instead of only returning the distance in nm). #5240

21.03.0 - 2021-02-24

Commits

Highlights

The "Meshes" tab was overhauled, so that it displays generated isosurfaces and imported meshes. Generated isosurfaces can be jumped to, reloaded, downloaded and removed. #4917
Before uploading a dataset webKnossos automatically checks whether a conversion and scale are needed. Additionally, the Upload UI was improved. #5081
Support for KNOSSOS cubes data format was removed. Use the webKnossos cuber tool to convert existing datasets saved as KNOSSOS cubes. #5085

Added

Added an explicit /signup (or /auth/signup) route. #5091
Added the annotation option "center new nodes" to switch whether newly created nodes should be centered or not. #4150
For webKnossos maintenance, superUsers can now join organizations without being listed as a user there. #5151
Added the possibility to track events for analytics in the backend. #5156

Changed

Changed the font to Titillium Web. #5161
Made the isosurface feature in the meshes tab more robust. If a request fails, a retry is initiated. #5102
Support for the old invite links was removed. These contained the organization name in the URL. The new links contain a token (can be generated in the users view). For instances with a single organization the old invite links should still work. #5091
Users are no longer allowed to deactivate their own accounts. #5070
Users are asked to confirm when leaving the dataset upload view while an upload is still running. #5051
Mailer now uses only TLS1.2 instead of JDK default. #5138
Make keyboard-driven movement through the dataset better aligned with the configured move value in certain scenarios. #5201
User experience domains are now separated by organization. #5149
Changed the default request timeouts for standalone datastores and tracingstores to match those of local ones (10000s instead of 75s). #5174

Fixed

Fixed a bug where the user could delete teams that were still referenced in annotations, projects or task types, thus creating invalid state. #5108
Fixed a bug where an error occurred when clicking on the hours/week graph in the statistics overview page. #4779
Fixed a bug where the listing of users that have open tasks of a project failed. #5115
Fixed a bug that task scripts weren't correctly re-initialized when a new task was requested. This happened when certain conditions were met. #5199
Fixed some scenarios where the Meshes tab could cause errors (e.g., when the UI was used but no segmentation layer was available). #5142
Fixed a bug where the user (and telemetry) would get a cryptic error message when trying to register with an email that is already in use. #5152
Fixed a bug where default dataset configuration could not be loaded if a dataset was accessed via sharing token #5164
Fixed a bug where viewing a volume task as compound annotation failed for tasks with single instances. #5198

Removed

The isosurface setting was removed. Instead, isosurfaces can be generated via the "Meshes" tab. Also note that the Shift+Click binding for generating an isosurface was removed (for now). Please refer to the "Meshes" tab, too. #4917

21.02.1 - 2021-02-03

Commits

Fixed

Fixed a bug where the listing of users that have open tasks of a project failed. #5115
Fixed shift+clicking isosurfaces in annotations which contain skeletons. #5257

21.02.0 - 2021-01-20

Commits

Highlights

The dataset import UI was streamlined by making it clearer when automatic suggestions are available for the dataset properties. Previously, these suggestions were applied automatically which could cause some confusion. #4944
Added the possibility to generate skeletons from an HDF5 agglomerate file mapping on-the-fly. With an activated agglomerate file mapping, use Shift + Middle Mouse Click to import a skeleton of the cell into the annotation. Alternatively, use the button in the segmentation tab to import a skeleton of the centered cell into the annotation. #4958

Added

Added a context menu via Shift & Right Click that provides easy access to skeleton functionalities and additional information. #4950
Added a cleanup procedure for erroneous uploads, so failed uploads can be retried without changing the dataset name. #4999

Changed

Suggestions for the datasource settings of a dataset are no longer applied automatically. They can be applied optionally now. #4944
The brush tool is disabled in low magnifications (magnification 16 and lower) to avoid performance problems when annotating. #5017
The fill tool is disabled in low magnifications (magnification 2 and lower) to avoid producing spotty annotations (caused by needing too much main memory). #5050
Users can now join multiple organizations, admins can now invite users by email address, skipping the manual user activation step. #4984
Dataset Manager role now additionally grants permission to create explorative annotations on all datasets. #5037

Fixed

Fixed a bug where importing NMLs failed if they had unescaped greater-than signs inside of attributes. #5003
Mitigate errors concerning localStorage quotas in the datasets dashboard. #5039
Fixed a bug where viewing a dataset via sharingToken crashed. #5047

21.01.0 - 2020-12-21

Commits

Highlights

The menu for viewing, editing and creating annotations for a dataset in the dashboard was cleaned up a bit. Creating a hybrid (skeleton + volume) annotation is now the default way of annotating a dataset. The other options are still available via a dropdown. #4939

Added

Datasets without any layer are now considered unimported. #4959

Changed

For 2d-only datasets the view mode toggle is hidden. #4952
Persist the selected overwrite behavior for hybrid and volume annotations. #4962
Backend NML parser now allows NML nodes without radius attribute. Instead, their radius now defaults to a value of 1.0, which is also the new default value for initial nodes. Note that the node radius is only relevant when default setting “overwrite node radius” is disabled. #4982

Fixed

Fix crash for trees with high comment count (> 100000 nodes). #4965
Fix the upload of single file datasets. #4977

20.12.0 - 2020-11-23

Commits

Highlights

Added multi-resolution volume annotations. As a result, volume tracings can be viewed even when zooming out to downsampled magnifications. Note that already existing volume tracings will still only contain data in the first magnification. If you want to migrate an old volume tracing, you can explicitly trigger the downsampling in the sidebar's layer settings. #4755
Improved performance of volume annotations (brush and trace tool). #4848

Added

The total length of skeletons can now be measured using the dropdown in the tree list tab. Also, the frontend API received the methods api.tracing.measureTreeLength and api.tracing.measureAllTrees. #4898
Introduced an indeterminate visibility state for groups in the tree tab if not all but only some of the group's children are visible. Before, the visibility of those groups was shown as not visible which made it hard to find the visible trees. #4897
Dataset uploads on a specific Datastore can now be restricted to a single organization. #4892
Added a button to set the color of a tree in the trees tab view. #4907

Changed

In the tree tab, all groups but the root group are now collapsed instead of expanded when opening a tracing. #4897
New volume/hybrid annotations are now automatically multi-resolution volume annotations. #4755
Re-enabled continuous brush strokes. This feature ensures that even fast brush strokes are continuous and don't have "holes". #4924
The Historgram now has a correct linear scale. #4926

Fixed

Fixed the disappearing of dataset settings after switching between view mode and annotation mode. #4845
Fixed a rare error in the agglomerate mapping for large datasets. #4904
Fixed a bug where in volume annotation zip upload some buckets were discarded. #4914
Fixed the Dataset import which was broken temporarily. #4932
Fixed the upload of multiple volume annotations with similar data zip names. #4915

20.11.0 - 2020-10-26

Commits

Highlights

Improved the toolbar to make the different webKnossos tools easier to use. For example, the fill-tool and the cell-picker have a dedicated button in volume annotations now. #4875
The dataset upload is now more robust and can recover from a failed upload of a data chunk. #4860
Movements in the 3D viewport are now time-tracked. #4876

Added

Hybrid tracings can now be imported directly in the tracing view via drag'n'drop. #4837
The find data function now works for volume tracings, too. #4847
Added admins and dataset managers to dataset access list, as they can access all datasets of the organization. #4862
Added the possibility to move the current position by dragging with the middle-mouse-button (regardless of the active tool). #4875
Sped up the NML parsing via dashboard import. #4872

Changed

Brush circles are now connected with rectangles to provide a continuous stroke even if the brush is moved quickly. #4785
The position input of tracings now accepts decimal input. When losing focus the values are cut off at the comma. #4803
webknossos.org only: Accounts associated with new organizations can now be created even when a datastore is unreachable. The necessary folders are created lazily when needed. #4846
When downloading a volume tracing, buckets containing a single 0 byte, that were created to restore older versions, are now skipped. #4851
Task information CSV now contains additional column creationInfo, containing the original NML filename for tasks based on existing NMLs. #4866
The default overwrite-behavior in volume annotating changed so that erasing with the brush- or trace-tool always erases all voxels (regardless of their segment id). Before that, only the current segment id was overwritten by default. As before, this behavior can be toggled by pressing CTRL. Alternatively, one can now also switch the mode in the toolbar. #4875

Fixed

Fixed failing histogram requests for float layers with NaN values. #4834

20.10.0 - 2020-9-21

Commits

Highlights

Added the possibility to undo and redo volume annotation strokes. #4771
Isosurface generation now also supports volume tracings (without fallback layers). #4567
Added a tool to initiate a flood fill in a volume tracing with the active cell id. #4780
Added the possibility to navigate to the preceding/subsequent node by pressing "ctrl + ," or "ctrl + ." in a skeleton tracing. #4147

Added

Added the possibility to merge volume tracings both via file upload (zip of zips) and when viewing projects/tasks as compound annotations. #4709
Added the possibility to remove the fallback segmentation layer from a hybrid/volume tracing. Accessible by a minus button next to the layer's settings. #4741

Changed

When d/f switching is turned off and a slice is copied with the shortcut v, the previous slice used as the source will always be slice - 1 and shift + v will always take slice + 1 as the slice to copy from. #4728
Disabled the autofill feature of the brush when using this tool to erase data. #4729
The rotation buttons of the 3D-viewport no longer change the zoom. #4750
Improved the performance of applying agglomerate files. #4706
When uploading tasks via NML, NML are shown in the task modal instead of a toast. #4723

Fixed

Improved the data loading behavior for flight and oblique mode. #4800
Fixed an issue where in some cases the tree list was only visible after the window was resized. #4816
Fixed a bug where some volume annotations that had been reverted to a previous version became un-downloadable. #4805
Fixed a UI bug where some tooltip wouldn't close after editing a label. #4815

20.09.0 - 2020-8-20

Commits

Highlights

Improved the distinguishability of segments by improving the color generation and also by rendering patterns within the segments. The pattern opacity can be adapted in the layer settings (next to the opacity of the segmentation layer). #4730
Added the possibility to move nodes in skeleton tracings. This can be done either by pressing CTRL + arrow key or by dragging while holding CTRL. #4743

Added

Added the possibility to delete datasets on disk from webKnossos. Use with care. #4696
Added error toasts for failing bucket requests. #4740
Added a list of all projects containing tasks of a specific task type. It's accessible from the task types list view. #4420

Changed

When d/f switching is turned off and a slice is copied with the shortcut v, the previous slice used as the source will always be slice - 1 and shift + v will always take slice + 1 as the slice to copy from. #4728
Disabled the autofill feature of the brush when using this tool to erase data. #4729
The rotation buttons of the 3D-viewport no longer change the zoom. #4750
Improved the performance of applying agglomerate files. #4706
In the Edit/Import Dataset form, the "Sharing" tab was renamed to "Sharing & Permissions". Also, existing permission-related settings were moved to that tab. #4683
Improved rotation of camera in 3D viewport. #4768
Improved handling and communication of failures during download of data from datasets. #4765
The volume annotation tools in hybrid tracings are disabled while in merger mode. #4757
The title of a tab now shows the active tracing or dataset as well as the corresponding organization. #4653
When viewing or tracing a dataset with only one slice (2D data) the default layout displays only the XY plane. The other viewports can still be accessed by changing the viewport tab. #4738

Fixed

Speed up NML import in existing tracings for NMLs with many trees (20,000+). #4742
Fixed tree groups when uploading NMLs with multi-component trees. #4735
Fixed that invalid number values in slider settings could crash webKnossos. #4758
Improved resilience in time tracking, preventing overlapping timespans. #4830

20.08.0 - 2020-07-20

Commits

Highlights

Added the possibility to have multiple user-defined bounding boxes in an annotation. Task bounding boxes are automatically converted to such user bounding boxes upon “copy to my account” / reupload as explorational annotation. #4536
Separated the permissions of Team Managers (now actually team-scoped) and Dataset Managers (who can see all datasets). The database evolution makes all Team Managers also Dataset Managers, so no workflows should be interrupted. New users may have to be made Dataset Managers, though. For more information, refer to the updated documentation. #4663
Backend NML parser no longer rejects NMLs with trees that have multiple connected components. Instead, it splits those into one separate tree per component. #4688

Added

Added the possibility to adjust the minimum and maximum value of the histogram for a layer. This option can be opened in the top right corner of the histogram. #4630
Added a warning to the segmentation tab when viewing uint64 bit segmentation data. #4598
Added the possibility to have multiple user-defined bounding boxes in an annotation. Task bounding boxes are automatically converted to such user bounding boxes upon “copy to my account” / reupload as explorational annotation. #4536
Added additional information to each task in CSV download. #4647
Added the possibility to configure the sender address used in emails wk sends (mail.defaultSender in application.conf). #4701
Added a warning during task creation if task dataset cannot be accessed by project team members. #4695
Included the server time in error messages, making debugging misbehavior easier. #4707

Changed

Separated the permissions of Team Managers (now actually team-scoped) and Dataset Managers (who can see all datasets). The database evolution makes all Team Managers also Dataset Managers, so no workflows should be interrupted. New users may have to be made Dataset Managers, though. For more information, refer to the updated documentation. #4663
Refined all webKnossos emails for user signups etc. Switched emails to use HTML templates for more bling bling. #4676
Backend NML parser no longer rejects NMLs with trees that have multiple connected components. Instead, it splits those into one separate tree per component. #4688

Fixed

Fixed that merger mode didn't work with undo and redo. Also fixed that the mapping was not disabled when disabling merger mode. #4669
Fixed a bug where webKnossos relied upon but did not enforce organization names to be unique. #4685
Fixed that being outside of a bounding box could be rendered as if one was inside the bounding box in some cases. #4690
Fixed a bug where admins could revoke their own admin rights even if they are the only admin in their organization, leading to an invalid state. #4698
Fixed a bug where webKnossos ignored existing layer category information from datasource-properties.json when exploring layers on disk. #4694

19.04.0 - 2019-04-01

Commits

Highlights

This release multiple new interactions are expanding webKnossos: - Added merger mode for skeleton and hybrid tracings. It allows to merge segments from e.g. generated oversegmentations. #3619 - Added a shortcut (Q) and button to screenshot the tracing views. #3834 - Rendered isosurfaces in the 3D viewport can now be interacted with. Shift+Click on an isosurface will jump exactly to where you clicked. Also, hovering over an isosurface will highlight that cell in all viewports. #3858 - Neuroglancer precomputed datasets can now be added to webKnossos using the webknossos-connect service. #3843

Also the data viewing and tracing workflow is smoothed further: - Different loading strategies are now supported ("best quality first" and "progressive quality"). Additionally, the rendering can use different magnifications as a fallback. #3801 - Performance improvements #3880 & #3902

Added

Rendered isosurfaces in the 3D viewport can now be interacted with. Shift+Click on an isosurface will jump exactly to where you clicked. Also, hovering over an isosurface will highlight that cell in all viewports. #3858
webKnossos now comes with a list of sample datasets that can be automatically downloaded and imported from the menu. #3725
Added a shortcut (Q) and button in the actions dropdown to screenshot the tracing views. The screenshots will contain everything that is visible in the tracing views, so feel free to disable the crosshairs in the settings or toggle the tree visibility using the (1) and (2) shortcuts before triggering the screenshot. #3834
Neuroglancer precomputed datasets can now be added to webKnossos using the webknossos-connect (wk-connect) service. To setup a wk-connect datastore follow the instructions in the Readme. Afterwards, datasets can be added through "Add Dataset" - "Add Dataset via wk-connect". #3843
Added support for mappings for 8-bit and 16-bit segmentation layers. #3953
The dataset settings within the tracing view allow to select between different loading strategies now ("best quality first" and "progressive quality"). Additionally, the rendering can use different magnifications as a fallback (instead of only one magnification). #3801
The mapping selection dropdown is now sorted alphabetically. #3864
Added the possibility to filter datasets in the dashboard according to their availability. By default, datasets which are missing on disk (e.g., when the datastore was deleted) are not shown anymore. This behavior can be configured via the settings icon next to the search box in the dashboard. #3883
Added merger mode for skeleton and hybrid tracings. It allows to merge segments from e.g. generated segmentations. #3619
The HTML template now includes SEO tags for demo instances and hides internal instances from search engines.
Segmentation ID mappings can now be used in volume and hybrid tracings. #3949
A maximize-button was added to the viewports in the annotation view. Maximization can also be toggled with the . shortcut. #3876
webknossos-connect now starts with webKnossos on local and development instances by default. #3913
The visibilities of trees in a skeleton tracing is now persisted across page loads. #3942
Added a button for each color layer to enable/disable the layer. #3943
Paginated routes now send a X-Total-Count HTTP header which shows how many entries were found in total. #3899

Changed

Improved the flight mode performance for tracings with very large trees (>80.000 nodes). #3880
Tweaked the highlighting of the active node. The inner node looks exactly as a non-active node and is not round, anymore. An active node is circled by a "halo". In arbitrary mode, the halo is hidden and the active node is round. #3868
Improved the performance of moving through a dataset which should make the overall interaction smoother. #3902
Brush size is independent of zoom value, now. This change simplifies volume annotations, as brush sizes can be adapted to certain structures (e.g., vesicles) and don't need to be changed when zooming. #3868
Reworked the search in the trees tab. #3878

Fixed

Fixed a bug where failed large save requests lead to inconsistent tracings on the server. #3829
Fixed the setting which enables to hide the planes within the 3D viewport. #3857
Fixed a bug which allowed the brush size to become negative when using shortcuts. #3861
Fixed interpolation along z-axis. #3888
Fixed that the halo of the active node could cover other nodes. #3919
Fixed that the 3D viewport was partially occluded due to clipping distance issues. #3919
Fixed that scrolling with the mouse wheel over a data viewport also scrolled the page. This bug appeared with the new Chrome version 73. #3939

Removed

Removed FPS meter in Annotation View. #3916

19.03.0 - 2019-03-04

Commits

Highlights

The tracing view got two major improvements:
Data rendering is now fully using the available space and doesn't have to be quadratic anymore. Increasing the size of a viewport will result in more data being rendered (as opposed to the same data will be upscaled). #3634
The active node is highlighted with a "halo ring". Additionally, the node is also rendered as a circle. In flight and oblique modes the halo is hidden. #3731
Added the possibility to create volume annotation tasks. When creating a task type, select whether to create volume or skeleton tasks. Compound viewing and file upload for volume tasks is not yet supported. #3712
Mappings for segmentations will be read automatically from the file system. It's not necessary to define the mappings within the datasource-properties.json anymore. #3720

Added

Added the possibility to create volume annotation tasks. When creating a task type, select whether to create volume or skeleton tasks. Note that compound viewing for volume tasks is not supported yet. Same for creating volume tasks from uploaded nml/data files. #3712
Added an UI to select a mapping for a segmentation layer. The UI is placed in the segmentation tab within the tracing view. #3720
Added a button to jump to actual data if the bounding box of a dataset contains a lot of black data. #3682

Changed

Data rendering is not tied to square viewports, anymore. As a result the screen space is used more efficiently to show data. Also, increasing the size of a viewport will result in more data being rendered (as opposed to the same data will be upscaled). #3634
Mappings for segmentations will be read automatically from the file system. It's not necessary to define the mappings within the datasource-properties.json, anymore. #3720

18.09.0 - 2018-08-20

Commits

Highlights

The dashboard gallery loads faster #3036 and tracings in the dashboard can show their descriptions #3035.
Managing new users got easier through "new inactive users" notifications #2994, and also team managers can activate them now #3050.
Improved the UI for sharing datasets and tracings #3029.
The tracing view got a progress-indicator #2935 and scale-bars #3049.
When merging datasets within a tracing via the merge-modal, the user can choose whether the merge should be executed directly in the currently opened tracing. Alternatively, a new annotation can be created which is accessible via the dashboard, as before #2935.

Added

Added two new properties to mapping json files. The colors: [<hsvHueValue1>, <hsvHueValue2>, ...] property can be used to specify up to 256 custom colors for the first 256 equivalence classes of the mapping. The hideUnmappedIds: <true|false> property indicates whether segments that were not mapped should be rendered transparently or not. #2965
Added a button for refreshing the dataset in the backend cache. #2975
Added the possibility to see the description of a tracing within the dashboard. #3035
Comments of tracing trees can now be cycled through by keeping n and p pressed. #3041
All dates in webknossos will be shown in the browser's timezone. On hover, a tooltip will show the date in UTC. #2916
When merging datasets within a tracing via the merge-modal, the user can choose whether the merge should be executed directly in the currently opened tracing. Alternatively, a new annotation can be created which is accessible via the dashboard (as it has been before).
Added shortcuts for moving along the current tracing direction in orthogonal mode. Pressing 'e' (and 'r' for the reverse direction) will move along the "current direction", which is defined by the vector between the last two created nodes.
Added a banner to the user list to notify admins of new inactive users that need to be activated. #2994
When a lot of changes need to be persisted to the server (e.g., after importing a large NML), the save button will show a percentage-based progress indicator.
Changing tabs in a tracing view will not disable the keyboard shortcuts anymore. #3042
Added the possibility for admins to see and transfer all active tasks of a project to a single user in the project tab#2863
Added the possibility to import multiple NML files into the active tracing. This can be done by dragging and dropping the files directly into the tracing view. #2908
Added placeholders and functionality hints to (nearly) empty lists and tables in the admin views. #2969
Added the possibility to copy volume tracings to own account
During the import of multiple NML files, the user can select an option to automatically create a group per file so that the imported trees are organized in a hierarchy. #2908
Added the option to display scale bars in the viewports for orthogonal mode. #3049
Added functions to the front-end API to activate a tree and to change the color of a tree. #2997
When a new team or project is created, invalid names will be directly marked in red. #3034
Added an error message to the NML upload if the needed permissions are missing for the upload. #3051
Comments can now contain references to nodes (#<nodeid>) or positions (#(<x,y,z>)). Clicking on such a reference activates the respective node or position and centers it. #2950
Added a default text to the task view to indicate, that no users are assigned to a task. #3030
