Breaking: #93083 - class.ext_update.php handling removed
See forge#93083
Description
Handling of old class. update scripts has been
dropped: The core introduced a much more solid API for extensions to
perform upgrades with the release of TYPO3 v9. That API matured
and many extensions use it in favor of the clumsy
class. solution. Removal of this functionality
within the extension manager has been long overdue and is finally done
with TYPO3 v11.
Impact
The class. was an old way for extensions to
perform upgrade steps. The TYPO3 core no longer supports this API.
Affected Installations
Some old-style extensions may still rely on this script. It's usage has been discouraged since the new upgrade wizards API.
Migration
Migrate class. to the upgrade wizard API of the
Install Tool.
