 - Improved error messages for starting jobs on datasets from other organizations. [#8181](https://github.com/scalableminds/webknossos/pull/8181)
 - Terms of Service for Webknossos are now accepted at registration, not afterward. [#8193](https://github.com/scalableminds/webknossos/pull/8193)
 - Removed bounding box size restriction for inferral jobs for super users. [#8200](https://github.com/scalableminds/webknossos/pull/8200)
+- Improved logging for errors when loading datasets and problems arise during a conversion step. [#8202](https://github.com/scalableminds/webknossos/pull/8202)
 
 ### Fixed
 - Fix performance bottleneck when deleting a lot of trees at once. [#8176](https://github.com/scalableminds/webknossos/pull/8176)
