The format is based on Keep a Changelog and this project adheres to Calendar Versioning 0Y.0M.MICRO. For upgrade instructions, please check the migration guide.

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.

21.06.0 - 2021-06-01

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
  • The visibility of meshes can now be toggled via the meshes tab. #5346
  • When exporting an user bounding box to tiff, the active mapping will now be applied to the exported data, as well. #5474
  • Changed the layout of the modal that informs the user about the success of task creations and changed the naming schema for the downloadable csv file containing the information about created tasks. #5491

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
  • Added support for flight- and oblique-mode when having non-uint8 dataset layers. #5396

Changed

  • webKnossos is now part of the image.sc support community. #5332
  • Meshes that are imported by the user in the meshes tab are now rendered the same way as generated isosurface meshes. #5326
  • 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 a bug in Safari which could cause an error message (which is safe to ignore). #5373
  • 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
  • Added the possibility to export also volume annotations as tiff (if long-runnings jobs are enabled). #5246
  • WKW Dataset uploads with missing mag or layer dir no longer fail, instead the paths are automatically added (defaults to color/1). #5285

Changed

  • Measured distances will be shown in voxel space, too. #5240
  • Improved documentation and inline-help for data import and conversion. #5420

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

  • 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

20.08.0 - 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

  • 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.

  • 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

Removed

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 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
  • 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
  • In the dashboard list of active tasks, the project name is now featured more prominently, as it switched places with the task type summary. #3792
  • Isosurfaces are now loaded from the middle outwards. #3818
  • The brush size will now be remembered across page reloads. #3827
  • Do not show publication view if no publications are specified. #3778

Fixed

  • Fixed an error that occured when changing the URL hash. #3746
  • Fixed a bug in the timeline chart rendering. The start and end time of the timeline chart now match the selected time range. #3772
  • The modals for a new task description and recommended task settings are no longer shown in read-only tracings. #3724
  • Fixed a rendering bug when opening a task that only allowed flight/oblique mode tracing. #3783
  • Fixed a bug where some NMLs caused the webKnossos tab to freeze during NML upload. #3758
  • Fixed a bug where some skeleton save requests were wrongly rejected if they were sent more than once. #3767
  • Fixed a bug which caused a wrong aspect ratio in the 3D viewport when changing the layout. #3817

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

  • 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

Changed

  • Added a checkbox to disable the warning when deleting a tree. An accidentally deleted tree can easily be restored using the Undo functionality. #2995
  • Improved the UI for sharing datasets and tracings. #3029
  • Team managers are now allowed to activate users (previously admin-only) #3050
  • Improved the loading time of datasets in the dashboard. #3036

Fixed

  • Fixed a bug where unloaded data was sometimes shown as black instead of gray. #2963
  • Fixed that URLs linking to a certain position in a dataset or tracing always led to the position of the active node. #2960
  • Fixed that setting a bounding box in view mode did not work. #3015
  • Fixed a bug where viewing Compound Annotations (such as viewing all instances of a task at once) failed with a permission issue. #3023
  • Fixed that the segmentation layer is loaded from the server even when the segmentation opacity is set to 0. #3067
  • Fixed a bug where the team name was not displayed in the task types view of admins. #3053

Commits

Highlights

  • Performance improvements for the tracing views. #2709 #2724 #2821
  • Added onboarding flow for initial setup of WebKnossos. #2859
  • The dataset gallery got a redesign with mobile support. #2761
  • Improved the import dialog for datasets. Important fields can now be edited via form inputs instead of having to change the JSON. The JSON is still changeable when enabling an "Advanced" mode. #2881
  • Added possibility to share a special link to invite users to join your organization. Following that link, the sign-up form will automatically register the user for the correct organization. #2898

Added

  • Added release version to navbar #2888
  • Users can view datasets in a table from the dashboard. That view also allows to create explorational tracings (which had to be done via the gallery view for non-admins before). #2866
  • Added the task bounding box of a skeleton tracing to NML files. #2827 \ Example: <taskBoundingBox topLeftX="0" topLeftY="0" topLeftZ="0" width="512" height="512" depth="512" />
  • Added the possibility to kick a user out of the organization team. #2801
  • Added a mandatory waiting interval of 10 seconds when getting a task with a new task type. The modal containing the task description cannot be closed earlier. These ten seconds should be used to fully understand the new task type. #2793
  • Added possibility to share a special link to invite users to join your organization. Following that link, the sign-up form will automatically register the user for the correct organization. #2898
  • Added more debugging related information in case of unexpected errors. The additional information can be used when reporting the error. #2766
  • Added permission for team managers to create explorational tracings on datasets without allowed teams. #2758
  • Added higher-resolution images for dataset gallery thumbnails. #2745
  • Added permission for admins to get tasks from all projects in their organization. #2728
  • Added the shortcut to copy the currently hovered cell id (CTRL + I) to non-volume-tracings, too. #2726
  • Added permission for team managers to refresh datasets. #2688
  • Added backend-unit-test setup and a first test for NML validation. #2829
  • Added progress indicators to the save button for cases where the saving takes some time (e.g., when importing a large NML). #2947
  • Added the possibility to not sort comments by name. When clicking the sort button multiple times, sorting is switched to sort by IDs. #2915
  • Added displayName for organizations. #2869
  • Added onboarding flow for initial setup of WebKnossos. #2859
  • Added the possibility to show the task in a random order. #2860

Changed

  • Improved the search functionality in the datasets view. The datasets will be sorted so that the best match is shown first. If a different sorting is desired, the sorting-arrows in the columns can still be used to change the sorting criteria. #2834
  • Improved performance in orthogonal mode. #2821
  • When deleting the last node of a tree, that tree will not be removed automatically anymore. Instead, the tree will just be empty. To remove that active tree, the "delete" shortcut can be used again. #2806
  • Renamed "Cancel" to "Reset and Cancel" for tasks. #2910
  • Changed the type of the initial node of new tasks to be a branchpoint (if not created via NML). #2799
  • The dataset gallery got a redesign with mobile support. #2761
  • Improved the performance of saving large changes to a tracing (e.g., when importing a large NML). #2947
  • Improved loading speed of buckets. #2724
  • Changed the task search, when filtered by user, to show all instead of just active tasks (except for canceled tasks). #2774
  • Improved the import dialog for datasets. Important fields can now be edited via form inputs instead of having to change the JSON. The JSON is still changeable when enabling an "Advanced" mode. #2881
  • Hid old paused projects in the project progress report even if they have open instances. #2768
  • Excluded canceled tasks and base tracings from the list at api/projects/:name/usersWithOpenTasks. #2765
  • Streamlined the order in which initial buckets are loaded when viewing a dataset. #2749
  • Reduced the number of scenarios in which segmentation-related warnings are shown (e.g, not for skeleton tracings when there are multiple resolutions for segmentations anyway). #2715
  • Email addresses for notifications about new users and about task overtime are no longer specified instance-wide but once per organization. #2939
  • Improved tracing view page load performance by decreasing WebGL shader compilation time. #2709
  • Improved error reporting for project progress page. #2955
  • Redesigned the user task list to make it easier to read the whole task description. #2861

Fixed

  • Fixed a bug which caused segmentation data to be requested as four-bit when four-bit-mode was enabled. #2828
  • Fixed a bug where possible comments or branchpoints sometimes were not properly deleted when deleting a node. 2897
  • Fixed a bug which caused projects to be unpaused when the project priority was changed. #2795
  • Fixed an unnecessary warning when deleting a tree in a task, that warned about deleting the initial node although the initial node was not contained in the deleted tree. #2812
  • Fixed a bug where the comment tab was scrolled into view horizontally if a node with a comment was activated. #2805
  • Fixed a bug in for Firefox users where a long tree list created an unnecessary scroll region. #2787
  • Fixed clicking on a task type within the task list page, so that the task type page will actually only show the linked task type. #2769
  • Fixed clicking on a project within the task list page, so that the project page will actually only show the linked project. #2759
  • Fixed a bug in the front-end API's setMapping call which caused ignored calls if the provided object was mutated. #2921
  • Fixed a bug where cell IDs in the segmentation tab were not shown for all zoomsteps. #2726
  • Fixed the naming of the initial tree in tasks. #2689
  • Fixed a regression affecting node selection, shortcuts and 3d viewport navigation. #2673
  • Fixed the dataset zip upload for datasets, which only have one data layer and no config file. #2840
  • Fixed a bug where task deletion broke the task listing for users who had active annotations for the task #2884
  • Fixed that decimal scales (e.g., 11.24, 11.24, 30) couldn't be defined for datasets in "simple" mode. #2912
