I think it's time to get the ball rolling on this. It'll be the first release post-3.0, so will likely have a few bumps to work through.
How about: Friday 13th - Create release branches & tag RC of all repos Monday 16th - Draft Release Blog Post (digest of changelogs) Thurs 19th - Tag 3.1.0 for all repos Fri 20th - Push 3.1.0-1.0.0 of CLI to npm & Post blog post The main feature of this release will be plugman-registry I think. That said, since CLI / Plugman aren't tied to cadence releases, I think it's just cordova-docs that is relevant.
