​19.07.0 - 2019-07-01

​Commits​

Highlights

• Added a histogram and min- / max-sliders to the dataset settings for each layer. This replaces the brightness and contrast settings. #4105​

• Added the possibility to enforce a certain magnification range for tasks (can be configured in the corresponding task type). #4101​

• Added the possibility for admins to add experience domains while creating new tasks. #4119​

• Added the possibility for admins to add experience domains while creating new tasks. #4119​

• Added a histogram to the dataset settings for each layer. It simplifies adjusting the brightness and contrast of a layer and replaces the brightness and contrast slider. #4105​

• The dataset and the explorative annotations table in the dashboard are now horizontally scrollable if the window is not wide enough. Additionally, clicking on the name of a dataset in the dataset table opens the dataset in view mode. #4136​

• Added an two additional buttons to the dropdown menu of the tree hierarchy view. On Click, one collapses the other expands all subgroups. #4143​

  Changed

• The tooltip of the timeline chart in the Time Tracking view now displays the duration in minutes:seconds. #4121​

• Reactivated and renamed the "Quality" setting to "Hardware Utilization". Using a higher value will render data in higher quality, but puts more stress on the user's hardware and bandwidth. #4142​

Fixed

• Fixed that team managers couldn't view time tracking details of other users anymore. #4125​

• Fixed the positioning of the tooltip of the timeline chart in the Time Tracking view. #4121​

• Fixed a rendering problem which caused a red viewport on some Windows machines. #4133​

Removed

• The brightness and contrast slider in the dataset got removed in favour of the new histogram feature. #4105​

​19.06.0 - 2019-05-27

​Commits​

Highlights

Changed

• Heavily improved mapping creation/activation performance. #4103​

• The NML parser now rounds floating point values in node coordinates. #4045​

• The time tracking view now displays dates instead of hours when having more then one day selected. The display id's in the timeline diagram are not the task ids. The tooltip of the timeline diagram also got a rework. #4028​

• Improved the editing of datasets. Changes suggested by webKnossos will be easier to recognize as suggestions. 4104​

• The time tracking view now displays dates instead of hours when having more than one day selected. The display id's in the timeline diagram are not the task ids. The tooltip of the timeline diagram also got a rework. #4028​

​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 :racing_car: #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​

• 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​

​19.02.0 - 2019-02-04

​Commits​

  Please see the migration guide on how to add publications.

• Also, this release includes new features that enrich the view of your data:

  • Isosurface computation can now be triggered for whole segments (shift + click on a segment in view mode). #3655​

  • Added the possibility to fade the alpha value of data layers. Also, a dataset can now contain both RGB and grayscale layers. #3670​

• The volume annotation brush tool will now automatically fill any enclosed areas if the brushed outline is closed in one stroke. #3698​

  ​​

Added

• Added the possibility to fade the alpha value of data layers. Also, a dataset can now contain both RGB and grayscale layers. #3670​

• Annotations for non-public datasets can now be shared using the "Share" functionality without making the dataset public. #3664​

• The volume annotation brush tool will now automatically fill any enclosed areas if the brushed outline is closed in one stroke. #3698​

  ​​

• Statistics are now separated by organization, rather than showing the webKnossos instance’s totals. #3663​

• NML files can be imported into arbitrary datasets. Users will be asked to confirm the import process if the dataset of the NML differs from the currently active dataset. #3716​

Fixed

• Fixed a rendering bug which caused data to be clipped in certain scenarios for datasets with anisotropic resolutions. #3609​

• Fixed a bug where saving tracings failed after they were open for >24h. #3633​

• Fixed a bug that resulted in slow data loading when moving quickly through a dataset. #3656​

• Fixed a bug which caused the wrong magnification to be rendered when zooming out very far. #3641​

• Fixed a bug which broke the functionality to toggle the visibility of a tree in a skeleton tracing. #3719​

​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​

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​

​18.08.0 - 2018-07-23

​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​
