 ### Changed
 - Loading of precomputed meshes got significantly faster (especially when using a mesh file for an oversegmentation with an applied agglomerate mapping). [#7001](https://github.com/scalableminds/webknossos/pull/7001)
 - Improved speed of proofreading by only reloading affected areas after a split or merge. [#7050](https://github.com/scalableminds/webknossos/pull/7050)
+- The minimum length of layer names in datasets was set from 3 to 1, enabling single-character names for layers. [#7064](https://github.com/scalableminds/webknossos/pull/7064)
 
 ### Fixed
 - Fixed that changing a segment color could lead to a crash. [#7000](https://github.com/scalableminds/webknossos/pull/7000)
