Upgrading a Patch Version (e.g. 6.0.0 to 6.0.1) (Symfony Docs) (original) (raw)
When a new patch version is released (only the last number changed), it is a release that only contains bug fixes. This means that upgrading to a new patch version should not cause any problems.
To upgrade to a new "patch" release, read theUpgrading a Minor Version article. Thanks to Symfony's backwards compatibility promise, it's always safe to upgrade to the latest "minor" version.
Tip
It is recommended to update to a new patch version as soon as possible, as important bugs and security vulnerabilities may be fixed in these new releases.
Upgrading other Packages
You may also want to upgrade the rest of your libraries. If you've done a good job with your version constraints in composer.json, you can do this safely by running:
Warning
Beware, if you have some unspecific version constraints in yourcomposer.json (e.g. dev-master), this could upgrade some non-Symfony libraries to new versions that contain backwards-compatibility breaking changes.
