There are many fixes already committed to the 4.5 branch of TYPO3 which haven't been released yet. 4.5.2 dates three months back. So we decided to release TYPO3 4.5.3 on:
Tuesday, 24th of May
Please take some time to checkout pending patches in our review system which you might want to get included in 4.5.3, and review them! See what was fixed since the release of 4.5.2 in our git repository.
Also check out the issue tracker. Filter by "Target Version" => "Core - 4.5.3" and you will see plenty of issues still not resolved, which you might want to try to tackle. If you see other issues not targetted for 4.5.3 which you feel important to address in our LTS release, please contact me through this typo3.projects.v4 list.
There will be a TYPO3Camp in Stuttgart during this weekend and we might have a session for bug fixing / reviewing so we might get some more things resolved during these days.
