 **`README.md` is the single source of truth for the repository version.**
 
-- **Bump the patch version on every PR** — increment `XX.YY.ZZ` (e.g. `01.02.03` → `01.02.04`) in `README.md` before opening the PR; the `sync-version-on-merge` workflow propagates it automatically to all badges and `FILE INFORMATION` headers on merge to `main`.
+- **Patch version is auto-bumped by the release workflow** — `release.yml` reads the current version from `README.md`, increments the patch (`XX.YY.ZZ` → `XX.YY.(ZZ+1)`), updates `README.md`, `templateDetails.xml`, and the matching channel in `updates.xml`, commits, pushes, then builds the ZIP. Manual bumping is no longer required.
 - The `VERSION: XX.YY.ZZ` field in `README.md` governs all other version references.
 - Version format is zero-padded semver: `XX.YY.ZZ` (e.g. `01.02.03`).
 - Never hardcode a specific version in document body text — use the badge or FILE INFORMATION header only.
 
 ### Joomla Version Alignment
 
-The version in `README.md` **must always match** the `<version>` tag in `manifest.xml` and the latest entry in `updates.xml`. The `make release` command / release workflow updates all three automatically.
+The version in `README.md` **must always match** the `<version>` tag in `templateDetails.xml` and the matching channel entry in `updates.xml`. The release workflow updates all three automatically.
+
+### Multi-Channel updates.xml
+
+`updates.xml` contains separate `<update>` blocks per stability channel (development, alpha, beta, rc, stable). Each release workflow only modifies its own channel using targeted Python regex replacement — other channels are preserved untouched. Joomla filters by the user's "Minimum Stability" setting.
 
 ```xml
-<!-- In manifest.xml — must match README.md version -->
-<version>01.02.04</version>
-
-<!-- In updates.xml — prepend a new <update> block for every release.
-     Note: the backslash in version="4\.[0-9]+" is a literal backslash character
-     in the XML attribute value. Joomla's update server treats the value as a
-     regular expression, so \. matches a literal dot. -->

+- Version format must be `XX.YY.ZZ`, not tag names like `v01`
+- Download URLs must point to Gitea (not GitHub) for all pre-release channels
