Upgrading a Patch Version (e.g. 6.0.0 to 6.0.1) ¶
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 the Upgrading 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:
1 |
$ composer update
|
Caution
Beware, if you have some unspecific version constraints in your
composer.json
(e.g. dev-master
), this could upgrade some
non-Symfony libraries to new versions that contain backwards-compatibility
breaking changes.
