The versions 10.4.7 and 9.5.21 of the TYPO3 Enterprise Content Management System have just been released.

  • TYPO3 9.5.21 LTS

Both versions are maintenance releases only.

Update September 10, 2020
Further release of TYPO3 v10.4.8 LTS affecting composer-based installations

We've released another TYPO3 v10 release on Thursday, September 10, 2020 – TYPO3 v10.4.8 LTS.

It seemed like not every TYPO3 user could update to the latest TYPO3 v10 version due to issues regarding resolving dependencies with Symfony 4 (which were accidentally raised to Symfony 5 due to a dependency-of-a-dependency issue). For this reason, we've created an intermediate package which is compatible with Symfony 4 + 5. We've included this in TYPO3 v10.4.8 now, so everybody who is using TYPO3 v10 with composer can safely upgrade now.  

TYPO3 installations in non-composer-mode ("zip download") and all TYPO3 v9 versions are NOT affected!

Further upgrade instructions

No database upgrades are required for these maintenance releases.


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:
