+## [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
+- Restore feature with selection of the last available backups (up to 5 per domain).
+- New API endpoints to list and restore backups:
+  - `GET /api/bcs/backups?repo_id=...`
+  - `POST /api/bcs/restore?repo_id=...&backup_id=...`
+
+### Safety
+- Restoring a backup triggers a “restart required” prompt to apply the recovered integration state.
+
+### Notes
+- This is a major release milestone consolidating install/update/uninstall, backup/rollback, and restore workflows.
+
+## [0.5.11] - 2026-01-18
+
+### Added
+- Automatic backup of existing custom components before install or update.
+- Backup retention with a configurable limit per domain.
+
+### Safety
+- Automatic rollback is triggered if an install or update fails after a backup was created.
+
+## [0.5.10] - 2026-01-17
+
+### Added
+- Store view controls: Filter and Sort dropdowns alongside the existing Category selector.
+
+### Fixed
+- Search input focus is preserved while typing (cursor no longer jumps out after re-render).
+
+## [0.5.9] - 2026-01-17
+
+### Changed
+- README is now collapsible with a preview by default (Show more / Show less).
+- Improved mobile readability by keeping long README content contained without affecting the page layout.
+
 ## [0.5.8] - 2026-01-17
 
 ### Changed
