 ### Added
+- When exploring remote URIs pasted from Neuroglancer, the format prefixes like `precomputed://` are now ignored, so users don’t have to remove them. [#8195](https://github.com/scalableminds/webknossos/pull/8195)
 
 ### Changed
 - Reading image files on datastore filesystem is now done asynchronously. [#8126](https://github.com/scalableminds/webknossos/pull/8126)
