Compatible Versions for TYPO3 v4.5 LTS
With the release of YAG Version 2.0 to TER we stopped the support for TYPO3 4.5 LTS in order to use advanced features of the newest Extbase and Fluid versions and also to work on compatibility with TYPO3 version 6.0 and beyond.
If you still use TYPO3 4.5 LTS and want to use YAG, you can download and install the extension and its prerequisites provided on this page.
