Symfony manages its releases through a time-based model. A new Symfony minor version comes out every six months, one in May and one in November.

Starting from the Symfony 3.x branch, the number of minor versions is limited to five per branch (X.0, X.1, X.2, X.3 and X.4). The last minor version of a branch (e.g. 3.4, 4.4, 5.4) is considered a long-term support version and the other ones are considered standard versions:

Version Type Bugs are fixed for Security issues are fixed for
Standard 8 months 14 months
Long-Term Support (LTS) 3 years 4 years

More information is available on the Symfony website.

You should be running one of the supported release numbers listed above in the rightmost column.

You can check the version that you are currently using by running:

composer show symfony/symfony | grep versions
