Release planning for v2

[consideRatio]

I'd like to work towards a v2 release with jupyterhub 5 and oauthenticator 17.

Todo

• Update base user environment to miniforge 24.7.1-0 (Python 3.12) #990
• Test and verify function against ubuntu 24.04
  • Integration tests
  • Unit tests: ci: run unit tests in ubuntu-24.04 github actions environment as well #993
• Transition to jupyterhub 5 (jupyterhub 5 #989)
• Transition to oauthenticator 17
  • Note that oauthenticator[azuread]>=16.0.4,<17 is installed, but we no longer need to specify azuread I think. Look it up in oauthenticator.
  • update oauthenticator to 17 #992
• Consider getting a release out for:

  • jupyterhub-systemdspawner>=1.0.1,<2

    • Ensure tests for jupyterhub 5 etc pass and refresh CI system things
      ci: test jupyterhub 5, python 3.12, ubuntu 24.04 systemdspawner#143
    • No merged PRs, not aiming for a release.

    • Make release, a PR related to jupyterhub 5 is merged.
      Add changelog for 1.1.0 firstuseauthenticator#58

    • Make release, things have happened since last.

  • jupyterhub-ldapauthenticator>=1.3.2,<2

24.04 is already in the test matrix, and JupyterHub 5 is done in #989

I want to try to put a lot less pressure on other projects when we prepare a release like this. I feel strongly that we should at most check if a project is "due" for a release and do no more coordination than that. Deciding that a distribution is ready for release should ideally not create time-pressured work in other repos. If they aren't ready or approximately ready to release when it's time to make a distro release, they shouldn't be in the distro release.

@consideRatio's been doing a lot of great work refreshing projects like ldapauthenticator, but I also want to make sure that work like that is not considered part of the release process for tljh or z2jh (i.e. I'm definitely not saying the work shouldn't be done, but it shouldn't be expected when another project is preparing a release, and typically shouldn't block a downstream release).

I went for 2.0.0b1

[consideRatio]

JupyterHub 5.2.0 seem to cause issues for tljh, as reported in the CI system here: https://github.com/jupyterhub/the-littlest-jupyterhub/actions/runs/11410693112.

I've pinned it to 5.1.0 for now via #1007, but we should have this debugged and resolved before release of v2.

JupyterHub 5.2.0 now functions, with systemdspawner 1.0.2 bugfix release, fixed in #1008.
