 # Changelog
 
-## [Unreleased] 
+## [Unreleased]
+### Fixed
+- Change ID of plugin back from `org.nixos.idea` in version 0.3.0.0 to
+  `nix-idea` from earlier versions. The different ID of version 0.3.0.0
+  causes *IntelliJ* and *JetBrains Marketplace* to treat version 0.3.0.0
+  as a different plugin instead of another version of the same plugin.
+  **Note that if you installed version 0.3.0.0 manually from the ZIP
+  file, you should uninstall it when updating to a new version.**
+## [0.3.0.0]
 ### Changed
 - Update project to build for recent IJ versions
