It doesn't change too much in practice with how Mesa updates typically have been handled under Fedora Linux, but now it's officially documented: Mesa graphics drivers have a permanent updates exception so new Mesa versions can be shipped as updates in Fedora stable releases.

Similar to Fedora's permanent updates exception for the Linux kernel that allows new major Linux kernel releases to be shipped down to stable Fedora versions as updates, their Mesa packages now officially have the same treatment.

New Mesa versions have typically been shipped down to Fedora stable users as updates but without a documented exception policy in place. The Fedora Engineering and Steering Committee (FESCo) has formally granted the permanent exception to make it clear going forward.

New Mesa versions are important for fixing graphics driver issues with games/apps, introducing new GPU hardware support in tandem with new kernel versions, bringing performance optimizations, and all-around useful updates for keeping as a leading-edge Linux platform with Fedora.

The permanent exception was granted via [1]this FESCo ticket .
