 - [ ] Make sure the build box (st2build002 at the time of writing) is working correctly.
-- [ ] Note whether Mistral has a new version branch: you'll need it for st2workroom later.
 - [ ] Launch `st2cd.prepare-for-release` workflow: `st2_release_version` has to have a patch (e.g. `1.2.0`), `st2_base_url` should __not__ be `localhost` (e.g. `http://st2build002:9101/v1/`).
 - [ ] Change the dev version in [st2web/package.json](https://github.com/StackStorm/st2web/blob/master/package.json#L4): e.g. if `1.2.0` is released then `1.3dev` should be in the file.
 - [ ] Change the dev version in [st2client](https://github.com/StackStorm/st2/blob/master/st2client/st2client/__init__.py) and [st2common](https://github.com/StackStorm/st2/blob/master/st2common/st2common/__init__.py): same rules as in the previous step apply.
