 to https://opendev.org/openstack/governance/src/branch/master/reference/pr
 ojects.yaml before the Extra-AC freeze date.\n\n\n\n2026.1 Election Nomina
 tion Begins\n\nCandidates interested in serving for the next calendar year
  (TC)\, or development cycle (PTL) should announce their candidacies and p
 latforms during this week.  Please see the Election site for specific timi
 ng information.\n\n

DESCRIPTION:Flamingo-3 milestone\n\nAugust 28\, 2025 is the Flamingo-3 mil

 by the review team and postponed until the next series development opens (
 which should happen when RC1 is published).\n\n\n\nRequirements freeze\n\n
 After the Flamingo-3 milestone\, only critical requirements and constraint
 s changes will be allowed. Freezing our requirements list gives packagers 
 downstream an opportunity to catch up and prepare packages for everything 
 necessary for distributions of the upcoming release. The requirements rema
 in frozen until the stable branches are created\, with the release candida
 tes.\n\n\n\n2026.1 Election Email Deadline\n\nContributors that will be in
  the electorate for the upcoming election should confirm their gerrit emai
 l addresses by this date (August 20th\, 2025 at 00:00 UTC). Electorate rol

 orate has time to ask candidates questions about their platforms and debat
