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.

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.

Hola, soy Wolfgang.
Desde 2006, he estado buceando profundamente en el fascinante mundo de TYPO3 - no es sólo mi profesión, sino también mi pasión. Mi camino me ha llevado a través de innumerables proyectos, y he creado cientos de video tutoriales profesionales centrados en TYPO3 y sus extensiones. Me encanta desentrañar temas complejos y convertirlos en conceptos fáciles de entender, lo que también se refleja en mis formaciones y seminarios.
Como miembro activo del Comité de Educación de TYPO3, me comprometo a mantener las preguntas del examen TYPO3 CMS Certified Integrator actualizadas y desafiantes.
Pero mi pasión no termina en la pantalla. Cuando no estoy buceando en las profundidades de TYPO3, a menudo me encontrarás en mi bicicleta, explorando los pintorescos senderos alrededor del lago Constanza. Estas excursiones al aire libre son mi equilibrio perfecto: mantienen mi mente fresca y siempre me aportan nuevas ideas.
