# SECURITY POLICY

## Supported Versions

Security fixes are not backported to older **minor** versions. They are either released as a patch to the latest minor version branch, or included in a new minor version.

When a new **major** version is released (`1.0`, `2.0`, etc), the previous one (`0.19.x`) will receive bug fixes for *at least* 3 months and security updates for 6 months after that new release comes out.

(This policy may change in the future and exceptions may be made on a case-by-case basis.)
