 ### Changed
 - Upgraded antd UI library to v4.24.8 [#6865](https://github.com/scalableminds/webknossos/pull/6865)
 - The view mode dropdown was slimmed down by using icons to make the toolbar more space efficient. [#6900](https://github.com/scalableminds/webknossos/pull/6900)
+- Updated the styling of the "welcome" screen for new users to be in line with the new branding. [#6904](https://github.com/scalableminds/webknossos/pull/6904)
 
 ### Fixed
 - Fixed a bug where N5 datasets reading with end-chunks that have a chunk size differing from the metadata-supplied chunk size would fail for some areas. [#6890](https://github.com/scalableminds/webknossos/pull/6890)
