+## [0.6.6] - 2026-01-18
+
+### Added
+- Source filter to limit repositories by origin: BCS Official, HACS, or Custom.
+- Visual source badges for repositories (BCS Official, HACS, Custom).
+- Restored HACS enable/disable toggle in the Store UI.
+
+### Changed
+- HACS repositories now display human-readable names and descriptions based on official HACS metadata.
+- Improved Store usability on mobile devices by fixing back navigation from repository detail view.
+
+### Fixed
+- Fixed missing HACS toggle after UI updates.
+- Fixed mobile browser back button exiting the Store instead of returning to the repository list.
+
+## [0.6.5] - 2026-01-18
+
+### Added
+- Separate handling of HACS official repositories with an enable/disable toggle in the Store UI.
+- HACS repositories are now loaded independently from the main store index.
+
+### Changed
+- Store index can remain minimal and curated; HACS repositories are no longer required in store.yaml.
+- Improved Store performance and clarity by clearly separating repository sources.
+
+### Fixed
+- Browser cache issues resolved by proper panel cache-busting for UI updates.
+
+### Internal
+- No changes to install, update, backup, or restore logic.
+- Fully backward compatible with existing installations and configurations.
+
+## [0.6.4] - 2026-01-18
+
+### Fixed
+- Fixed long Home Assistant startup times caused by background repository enrichment running too early.
+
+### Changed
+- Background repository enrichment is now started only after Home Assistant has fully started.
+- Repository cache updates now run fully asynchronous without blocking Home Assistant startup.
+
+### Internal
+- Improved alignment with Home Assistant startup lifecycle.
+- No functional changes to store behavior or UI.
+
+## [0.6.3] - 2026-01-18
+
+### Changed
+- Improved Store performance for large indexes by avoiding full metadata enrichment during list refresh.
+- Repository details are loaded on demand, reducing initial load time and network requests.
+- Index refresh is skipped when the index content has not changed.
+
+## [0.6.2] - 2026-01-18
+
+### Added
+- Selectable install/update version per repository (install older releases/tags to downgrade when needed).
+- New API endpoint to list available versions for a repository: `GET /api/bcs/versions?repo_id=...`.
+
+## [0.6.1] - 2026-01-18
+
+### Fixed
+- Restored integrations now correctly report the restored version instead of the latest installed version.
+- Update availability is correctly recalculated after restoring a backup, allowing updates to be applied again.
+- Improved restore compatibility with backups created before version metadata was introduced.
+
 ## [0.6.0] - 2026-01-18
 
 ### Added
