Security fixes

The Vulnerability Management team provides advisories with patches for the two previous releases of OpenStack. Older releases may or may not be supported by their stable maintenance teams, see below.

Stable branches

Stable branches are centralized efforts to maintain bugfixes and vulnerability fixes for released OpenStack project versions in ready-to-use branches.

Current stable release (Grizzly)

The current stable release branches are maintained by the openstack-stable-maint team. This team makes sure security fixes are included in the stable branch by the time security advisories go out.


The Folsom stable branch (stable/folsom) is still maintained (for a few more weeks) by the openstack-stable-maint team. Then it will switch to a dedicated team.


The Essex stable branch (stable/essex) is maintained by the openstack-essex-maint community team. Please join if you're still interested in Essex !


The Diablo stable branch (stable/diablo) is maintained by the openstack-diablo-maint community team. Please join if you're still interested in Diablo !
