 ## [Unreleased]
 
+## [09.00.00] - 2026-05-26
+
+### Added
+- PHPDoc on Priority 1 Enterprise classes (CliFramework, adapters, ApiClient)
+- Wiki: Coding-Standards page with PHPDoc standard, PHPCS exclusions, file patterns
+- CI: PHPStan enforced at level 6 (was advisory), PHPUnit blocks on failure
+
 ### Fixed
 - `updates_xml_build.php`: cascade entries down to lower channels — stable now writes all 5 entries instead of wiping them
 - `updates_xml_build.php`: separate Joomla stability tags (`dev`, `rc`) from Gitea release tags (`development`, `release-candidate`) — download URLs now point to correct release assets
