+## [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
+- Mobile UI layout stabilized to prevent horizontal shifting.
+- README rendering no longer expands the page width on mobile devices.
+- Tables and code blocks inside README now scroll within their container.
+- Floating action buttons removed to avoid UI overlap on small screens.
+- Header icon buttons improved for better visibility in light and dark mode.
+
+## [0.5.7] - 2026-01-17
+
+### Changed
+- Mobile UI improvements: removed floating action buttons to prevent overlay issues.
+- Improved responsive layout to avoid horizontal overflow (badges, URLs, descriptions).
+- README rendering on mobile is more stable (better wrapping and image scaling).
+- Header icon buttons are more readable in both light and dark mode.
+
+## [0.5.6] - 2026-01-17
+
+### Added
+- Repository uninstall support directly from the Store UI.
+- New backend API endpoint: `POST /api/bcs/uninstall`.
+- Automatic **reconcile**: repositories are marked as not installed when their `custom_components` directories are removed manually.
+
+### Changed
+- Installation & Updates section extended with an Uninstall button.
+- Store state now remains consistent even after manual file system changes.
+
+### Fixed
+- Repositories remained marked as installed after manual deletion of their domains.
+- UI cache issues caused by outdated static assets.
+
+## [0.5.5] - 2026-01-16
+
+### Fixed
+- Update entities now refresh their displayed name after store refreshes, so repository names replace fallback IDs (e.g. `index:1`) reliably.
+
+## [0.5.4] - 2026-01-16
+
+### Added
+- Native **Repair fix flow** for restart-required situations.
+- “Restart required” issues are now **fixable** and provide a confirmation dialog with a real restart action.
+
+### Changed
+- Restart-required issues are automatically cleared after Home Assistant restarts.
+- Update entities now fully align with official Home Assistant behavior (Updates screen + Repairs integration).
+
+### Fixed
+- Fixed integration startup issues caused by incorrect file placement.
+- Resolved circular import and missing setup errors during Home Assistant startup.
+- Ensured YAML-based setup remains fully supported.
+
+## [0.5.3] - 2026-01-16
+
+### Added
+- Native Home Assistant Update entities for installed repositories (shown under **Settings → System → Updates**).
+- Human-friendly update names based on repository name (instead of internal repo IDs like `index:1`).
+
+### Changed
+- Update UI now behaves like official Home Assistant integrations (update action is triggered via the HA Updates screen).
+
 ## [0.5.2] - 2026-01-16
 
 ### Added
