 - Added `.idea/changes.md` as the preferred in-project location for the detailed session change log.
 - Added release notes support in the active Bahmcloud Store runtime path: backend provider fetching, a dedicated API endpoint, and panel display for the currently selected version when provider release notes are available.
 - Bumped the Home Assistant panel asset cache-buster from `v=109` to `v=110` so the updated frontend loads reliably after deployment.
+- Bumped the integration version from `0.7.2` to `0.7.3`.
+- Added the `0.7.3` release entry to `CHANGELOG.md` with the new release-notes and project-workflow changes.
 
 ### Documented
 - Captured the verified project identity from the repository and README files: Bahmcloud Store is a Home Assistant custom integration intended to behave like a provider-neutral store for custom integrations, similar to HACS but broader than GitHub-only workflows.
