This Month in TYPO3: December 2025

December closed out 2025 with solid releases and active community work. From security updates and tooling progress to conference highlights and upcoming events, this roundup captures where TYPO3 stands as it heads into 2026 — and introduces a new This Month in TYPO3 editor.
I’m Jürgen Pietschmann, AI and CKEditor Consultant at T3Planet and Keeen GmbH, happily taking the reins of this series from Sanjay — thank you for setting such a high bar. I’m stepping into 2026 with community energy to spare, inspired by the 2025 TYPO3 retrospective and the T3CON25 recap. I’m gearing up for my first TYPO3 conference in 2026, already buzzing to contribute more. If you’ve been waiting to get involved, now’s the perfect moment. Warm New Year wishes to everyone — let’s build better things together.
