 ### Fixed
 - Fixed a bug where brushing on a fallback segmentation with active mapping and with segment index file would lead to failed saves. [#7833](https://github.com/scalableminds/webknossos/pull/7833)
 - Fixed a bug where sometimes old mismatching javascript code would be served after upgrades. [#7854](https://github.com/scalableminds/webknossos/pull/7854)
+- Fixed a bug where dataset uploads of zipped tiff data via the UI would be rejected. [#7856](https://github.com/scalableminds/webknossos/pull/7856)
