After the previous alpha and beta releases this Release Candidate is one of the very last steps before the final version of TYPO3 4.3. - ![](https://news.typo3.com/typo3temp/assets/t3g/blog/gravatar/b8266fdc667b773926c59081862ab148.jpeg)[Oliver Hader](https://news.typo3.com/article/author/oliver-hader) So, what's changed in this release? ***General*** **Moved Advanced Frontend Editing to TER** The Advanced Frontend Editing extension that was added to the TYPO3 Core in the first beta release has now been removed from the Core and will be published in the TYPO3 Extension Repository (TER) as  in conjunction with the final release of TYPO3 4.3. The new frontend editing functionality has been developed as an extension all along and the required TYPO3 Core changes have been in place prior to the first beta release. Moving the extension out of the Core and to the TER offers more flexibility as bugfixes can be released independent of patch level releases for the TYPO3 Core.  This also allows new features to be added during the TYPO3 4.3 lifetime. **More than 50 issues fixed** In addition to the previously mentioned changes, more than 50 issues have been fixed in the last week, several of which were related to PHP 5.3 compatibility. ***Next steps to climb the TYPO3 4.3 hill*** Please test this Release Candidate as much as possible, especially the new features from the previous alpha and beta releases! If you're upgrading from a previous TYPO3 version, please be sure to execute the database analyzer and update wizard in the TYPO3 Install Tool. We will release another Release Candidate in one week and continue that process until we feel comfortable that the code base is ready for the final release. This means that you can expect the final version to be ready by the end of November 2009.
