The TYPO3 Core Team has released the maintenance versions 13.4.19 LTS and 12.4.38 LTS. Both releases contain bug fixes and stability improvements.

The TYPO3 Core Team released the maintenance versions TYPO3 13.4.19 LTS and TYPO3 12.4.38 LTS on October 14, 2025.

Both releases are pure maintenance releases without functional changes - this means: no new features, but various bug fixes and minor improvements for more stability.

What does this mean for you?

No rush to update. As these are maintenance releases, you don't have to update immediately. Many admins and integrators like to wait a few days for such releases to see if any unexpected problems arise.

A look at forge.typo3.org will help you to keep an eye on possible issues. If nothing critical appears there, you can install the update at your leisure during the next maintenance.

No database updates necessary. The installation runs as usual - either via Composer or via the classic source package from get.typo3.org. No additional upgrade steps are required. Further details can be found in the release notes for TYPO3 12.4.38 and TYPO3 13.4.19.

Hi, I'm Wolfgang.

I have been working with TYPO3 since 2006. Not in theory, but in real projects with real deadlines. I've probably had the problems you're having three times already.

At some point, I started putting my knowledge into video courses. Not because I like being in front of the camera, but because I kept hearing the same questions over and over again. There are now hundreds of videos. Every single one was the result of a specific question from a specific project.

What makes me different from a YouTube tutorial: I not only know the solution, but also the context. Why something works. When it doesn't work. And which mistakes you can avoid because I've already made them.

As a member of the TYPO3 Education Committee, I make sure that the certification exams are kept up to date. What is tested there flows directly into my courses.
