Release Notes for TYPO3 4.5.2

This document contains information about TYPO3 version 4.5.2 which was released on February 25, 2011.


This version is a maintenance release and contains bugfixes only. It solves some regressions which were introduced in 4.5.1. All users of 4.5.0 and 4.5.1 are strongly advised to upgrade.

Please note that since the release of 4.5.1, the development of the new (and old) Extension Manager is done again in the current typo3_src branch (in the main TYPO3 repository) so that there is no longer an external repository with the code. Also note that further issues with the Extension Manager should be posted on the regular bug tracker (https://forge.typo3.org/projects/typo3cms-core/issues > Category “Extension Manager”) instead of the external project on forge.
