I think it would be best to simply adjust it so that it aligns with the new dates of ansible-core, i.e.:
ansible-core beta releases get a Ansible alpha release a day later;
ansible-core’s rc releases gets Ansible beta releases a day later;
and ansible-core 2.19.0 GA gets Ansible feature freeze a day later;
Ansible 12.0.0rc1 a week after that;
and 1-2 weeks later 12.0.0 comes out.
WDYT?
And how should we adjust the release schedule at Ansible project 12.0 — Ansible Community Documentation? Simply strike through the dates and add an info box that basically says the above (in nicer wording), and replace the dates once we have more exact ones for ansible-core?
As far as I can see, the ansible-core 2.19 roadmap hasn’t changed yet. I’m not sure if we should change any dates if we don’t have ones from core that we can point to.
At the very least, we should announce both here on the forum and on Bullhorn (maybe simply mentioning the forum post) that we will delay Ansible 12 because of the ansible-core 2.19 release schedule update.
