TYPO3 4.5.0 rc3

Released 25.1.2011.

This is the third and last release candidate for the upcoming version 4.5 of TYPO3. It represents a definitive final rehearsal for the final release of tomorrow and contains an important hot-fix which made rc2 unuseable (no login possible).

Upgrading and compatibility

Download the packages from the download package page at typo3.org (at the bottom).

To upgrade an existing installation of 4.4 to 4.5rc3, please consider the following steps:

  • Visit the Install Tool:
    1. Run through "Update wizards" which are new in 4.5 (you can now go through them using the "Next" button)
    2. Don't forget to use the "Database COMPARE" section and apply all database schema changes.

To upgrade from an earlier alpha or beta release of 4.5, please follow the same steps mentioned above.

Note: If you have a "No page in rootline" problem: Please note that the table name "be_layouts" (and the referring fields in pages) were renamed to "backend_layout" in rc1, so if you have used the grid view before, you will have to go to DB COMPARE in the Install Tool at any case. After that you might need to go to DB Tools > Check Reference Integrity. There is no Upgrade Wizard for this.

New installations

Try out the introduction package(tar.gz) (zip) which provides a very easy way of installing TYPO3 and having some example setup already in place.

Changes since 4.4

Changes since 4.5.0rc2

Since rc2 yesterday, we've done various fixes between. For technical details see ChangeLog included in the typo3_src package.

The most annoying one is that one could not log into TYPO3 anymore in rc2 and some other issues related to the CSRF Protection and also some ExtDirect trouble on certain browers (Firefox 4 Beta, Safari, Chrome 9 beta, etc).

Other than that, the Linkvalidator team worked out a nice improvement on the usability of their module (in Web>Info panel). Check it out!

Translations Update

Translators might want to check out the Label changes in 45 page, which was updated with the information on the tiny label changes which happened after beta4 until now.

Next steps

Please take some time to test this rc3, report any new issues you find in our bug tracker.

Tomorrow we will package the final release - Version 4.5.0 - according to our Release Plan.
