Symfony blog posts for September 2026

This week, Symfony 6.4.45, 7.4.18, and 8.1.6 were released with numerous bug fixes and hardening improvements. Meanwhile, we introduced symfony lsp:check, a new command that brings Symfony-aware diagnostics to your CI pipeline, catching unknown routes, missing templates, and configuration errors. Finally, we announced that you'll be able to meet the Symfony Core Team at the API Platform Conference 2026 in Lille on September 17–18.
