+#### Themes and UI
+
+- Themes can now adjust Tailwind colors through CSS variables! ([Dashboard colors](/docs/themes/colors))
+- Alias Blueprint UI properties.
+
+#### URL updates
+
+- Updated the documentation link shown in the extensions admin page when you didn't install Blueprint properly.
+- Updated the API base URL to the new endpoint.
+
+#### Cache overlay (admin)
+
+- cacheOverlay was removed a while ago, but it's CSS was still there. This has now been fixed!
+
+#### CLI
+
+- The CLI did not automatically put [Blueprint Docker](https://github.com/blueprintframework/docker) installations out of maintenance mode.
+- When upgrading, Blueprint did not migrate hidden files and directories at directory moveover, causing them to be deleted. It is important to note that this fix is for a bug in the initial upgrading process. The fix will only work for upgrading **from** this release, **not to**.
