Release Notes

Important

  • Mirantis Container Runtime 25.0 follows the version numbering scheme of the upstream Moby and Docker CLI projects. Mirantis may skip upstream versions released in short succession, though, and opt instead to release a patch that contains the content of all upstream versions released in the intervening period since the previous MCR 25.0 patch release.

  • Users running MSR 2.9.16 or earlier must upgrade to MSR 2.9.17 or later before upgrading to MCR 25.0.
