2. attention: symfony/dependency-injection 7.4 can break TYPO3 systems
Since 27.11.2025, version 7.4 of the symfony/dependency-injection package has been causing problems in TYPO3 installations. Extensions that were written to be compatible across versions are particularly affected. The new version forces Composer to load all PHP files. This can lead to errors. A temporary fix is to explicitly request version 7.3.x in composer.json.

3. composer 2.9 brings automatic security check for TYPO3
Composer 2.9 is here and brings three practical new features. The automatic blocking of insecure packages is particularly relevant. By default, Composer prevents updates to packages with known security vulnerabilities. This reduces the risk of rolling out vulnerable versions in production environments. There are also new CLI commands for repository management and automatic resolution of lockfile conflicts.

4. TYPO3 v14: Asset handling gets leaner - what's changing
TYPO3 v14 tidies up asset handling. HTTP Response Compression and Asset Concatenation will be removed. Many instances are not affected by this. There are sensible alternatives for the others. Compression is handled more efficiently by modern web servers. And with HTTP/2, asset concentration is often no longer necessary. This article shows you how to check whether you are affected and which steps make sense.

Wie schrijft hier?
Hoi, ik ben Wolfgang.
Sinds 2006 duik ik diep in de fascinerende wereld van TYPO3 - het is niet alleen mijn beroep, maar ook mijn passie. Mijn pad heeft me door talloze projecten geleid en ik heb honderden professionele video tutorials gemaakt over TYPO3 en zijn extensies. Ik hou ervan complexe onderwerpen te ontrafelen en ze om te zetten in eenvoudig te begrijpen concepten, wat ook tot uiting komt in mijn trainingen en seminars.
Als actief lid van het TYPO3 Education Committee zet ik me in om de TYPO3 CMS Certified Integrator examenvragen actueel en uitdagend te houden.
Maar mijn passie houdt niet op bij het scherm. Wanneer ik niet in de diepten van TYPO3 duik, vind je me vaak op mijn fiets, de schilderachtige paden rond het Bodenmeer verkennend. Deze uitstapjes in de buitenlucht zijn mijn perfecte balans - ze houden mijn geest fris en voorzien me altijd van nieuwe ideeën.
