-### 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
-- `updates_xml_build.php`: only emit `<client>site</client>` for templates and modules, not packages or components
-- `updates_xml_build.php`: preservation logic matches Joomla tag names when deciding which existing entries to keep
