Can be labelled **ready** when all other issues on this milestone are closed.

- [ ] run code analysis in VS in *Release* mode and address violations (send a regular PR which must be merged before continuing)
- [ ] if necessary, change `VERSION_SUFFIX` on the [CI Server](#{ci_server_url})
      to appropriate "-beta123" or "" (for non-betas) value and initiate a build
- [ ] check build
- edit draft release in [GitHub UI](https://github.com/FakeItEasy/FakeItEasy/releases):
    - [ ] ensure completeness of release notes, including non-owner contributors, if any (move release notes forward from any pre-releases to the current release)
    - [ ] attach main nupkg and/or analyzer nupkg, whichever have content to release
    - [ ] publish the release
- [ ] push nupkg(s) to NuGet
- [ ] de-list pre-release or superseded buggy NuGet packages if present
- [ ] update website with contributors list (if in place)
- [ ] tweet, mentioning contributors and post link as comment here for easy retweeting ;-)
- [ ] post tweet in [Gitter](https://gitter.im/FakeItEasy/FakeItEasy)
- [ ] post a link to the GitHub Release in each issue in this milestone, with thanks to contributors
eos

next_version_steps = <<-eos
- [ ] run `rake next_version[new_version]` to
    - create a pull request that changes the version in CommonAssemblyInfo.cs to the expected version (of form _xx.yy.zz_)
    - create a new draft GitHub Release
    - create a new milestone for the next release
    - create a new issue (like this one) for the next release, adding it to the new milestone
- [ ] close this milestone
