Yesterday I was very brave and upgraded my Typo3 on linux.bigga.de from 4.2.10 (stable) to 4.3 Beta2. I thought, it's a good idea to work already on a non-production system with the future typo3-release.

4.3 seems to be much bigger than 4.2. Archive size increases from 7,8M to 12M. This is for sure due to some backports from Forge (Typo3v5) to enable the MVC-concept in extensions already in Typo3v4.

After going step by step through the upgrade wizard, everything seemed to be fine. But then I tried to add a post to the t3blog and I failed adding any content.

I was trying a while and removed finally tinyrte and reinstalled htmlarea RTE. Now, I can add contents again but have to use the very slow (!) RTE again :-(

Other uses already noticed this "bug". I just added some comments to the bugtracker:
