+## [0.5.2] - 2026-01-16
+
+### Added
+- Install and update backend endpoints (`POST /api/bcs/install`, `POST /api/bcs/update`) to install repositories into `/config/custom_components`.
+- Installed version tracking based on the actually installed ref (tag/release/branch), stored persistently to support repositories with outdated/`0.0.0` manifest versions.
+- API fields `installed_version` (installed ref) and `installed_manifest_version` (informational) to improve transparency in the UI.
+
+### Changed
+- Update availability is now evaluated using the stored installed ref (instead of `manifest.json` version), preventing false-positive updates when repositories do not maintain manifest versions.
+
+### Fixed
+- Repositories with `manifest.json` version `0.0.0` (or stale versions) no longer appear as constantly requiring updates after installing the latest release/tag.
