We are winding up work on 2.13.3. There are still some in-flight issues and PRs, so I’ve pushed the date on the milestone forward to June 8. (And, it might slip again.)
The links in the first post in this topic are still usable for seeing how the release is shaping up.
Re: deprecations, in the release notes we’ll include the appropriate -Wconf/@nowarn incantations for suppressing them, to ease the upgrade. (We hope upgraders won’t leave them suppressed indefinitely, but the suppression can be useful for upgrading in stages.)
