@@ -15,6 +15,7 @@ For upgrade instructions, please check the [migration guide](MIGRATIONS.released
 - Segment statistics are now available for ND datasets. [#7411](https://github.com/scalableminds/webknossos/pull/7411)
 - Added support for uploading N5 and Neuroglancer Precomputed datasets. [#7578](https://github.com/scalableminds/webknossos/pull/7578)
 - Webknossos can now open ND Zarr datasets with arbitrary axis orders (not limited to `**xyz` anymore). [#7592](https://github.com/scalableminds/webknossos/pull/7592)
+- Added a new "Split from all neighboring segments" feature for the proofreading mode. [#7611](https://github.com/scalableminds/webknossos/pull/7611)
 
 ### Changed
 - Datasets stored in WKW format are no longer loaded with memory mapping, reducing memory demands. [#7528](https://github.com/scalableminds/webknossos/pull/7528)
