- Release process
-
-
- Going through an example of releasing NixOS 19.09:
-
-
-
- One month before the beta
-
-
-
-
- Create an announcement on Discourse as a warning about upcoming beta feature freeze in a month. See this post as an example.
-
-
-
-
- Discuss with Eelco Dolstra and the community (via IRC, ML) about what will reach the deadline. Any issue or Pull Request targeting the release should be included in the release milestone.
-
-
-
-
- Remove attributes that we know we will not be able to support, especially if there is a stable alternative. E.g. Check that our Linux kernels’ projected end-of-life are after our release projected end-of-life.
-
-
-
-
-
-
- At beta release time
-
-
-
-
- From the master branch run:
-
-
-git checkout -b release-19.09

-
-

-
-git tag --annotate --message="Release 19.09-beta" 19.09-beta
-git push upstream 19.09-beta
-
-
-
-
- On the master branch, increment the .version file
-
-
-echo -n "20.03" > .version
-
-
-
-

-
- Release Management Team
-
-
- For each release there are two release managers. After each release the release manager having managed two releases steps down and the release management team of the last release appoints a new release manager.
-
-
-
- This makes sure a release management team always consists of one release manager who already has managed one release and one release manager being introduced to their role, making it easier to pass on knowledge and experience.
-
-
-
- Release managers for the current NixOS release are tracked by GitHub team @NixOS/nixos-release-managers.
-
-
-
- A release manager’s role and responsibilities are:
-
-
-
-
-
- manage the release process
-
-
-
-
- start discussions about features and changes for a given release
-
-
-
-
- create a roadmap
-
-
-
-
- release in cooperation with Eelco Dolstra
-
-
-
-
- decide which bug fixes, features, etc… get backported after a release
