TYPO3 13.4.1 and 12.4.23 maintenance releases published

Categories: Development, TYPO3 CMS Created by Oliver Hader
The versions 13.4.1 and 12.4.23 of the TYPO3 Enterprise Content Management System have just been released.

The following TYPO3 updates have been released:

  • TYPO3 13.4.1 LTS
  • TYPO3 12.4.23 LTS

Both versions are maintenance releases only.

Further upgrade instructions

Unfortunately a flaw in 3rd party package symfony/type-info, revealed by reflection-docblock v5.6.0 (which was released minutes after the recent TYPO3 updates) causes a code-compatibility issue. This error only affects composer-based installations.

Our suggested work-around is to manually downgrade phpstan/phpdoc-parser:
composer update phpstan/phpdoc-parser --with "phpstan/phpdoc-parser:^1"

We expect this problem to be solved in the next symfony/type-info releases.

No further database upgrades are required for these maintenance releases.

Download

TYPO3 can be installed in various ways. For example the traditional way by using the source package at get.typo3.org or the modern way by setting up a project using composer, to name just two. Further details can be found in the according release notes:
