Frequently Asked Questions
Common questions about Symfony releases and lifecycle.
How long are Symfony versions supported?
Standard Symfony versions receive 8 months of bug fixes and 14 months of security fixes. LTS versions receive 3 years of bug fixes and 4 years of security fixes.
How often does Symfony release new versions?
Symfony ships a new major version every 2 years in November. Minor versions ship every 6 months in May and November.
Which Symfony version should I use?
Use the latest LTS release for production stability. Non-LTS versions are fine if your team can upgrade every 6 months.
Is upgrading Symfony difficult?
Symfony follows strict backward compatibility promises within major versions. The deprecation system warns you about upcoming changes well in advance, making upgrades predictable.
