Pre-Release

[x] Create release ticket on Releases board
[x] Make an announcement on #sig-product that team is doing a release. Include a link to the ticket from the release board.

[x] Create release PR Instructions

- [x] Deactivate old release if it's within same major version (state: deprecated). Verify with PO if you have doubts.

[x] Release relevant operators.
- [x] Tag release branch.
