Test output is the cleanest it's been in a while. Docs build is also clean except for a few missing glossary items (ping @RDaxini):

sphinx/source/user_guide/modeling_topics/spectrum.rst:55: WARNING: term not in glossary: 'aod' sphinx/source/user_guide/modeling_topics/spectrum.rst:63: WARNING: term not in glossary: 'clearsky_index' sphinx/source/user_guide/modeling_topics/spectrum.rst:67: WARNING: term not in glossary: 'clearsky_index' 

Of course those should be fixed, but not a blocker for the release IMHO.

I'll try out a pre-release to ensure that the new Trusted Publishing arrangement (#2549) works. If all goes well then I'll make the real release.

My two cents:

• Line 10 in current branch states:

  * Rename parameter name ``aparent_azimuth`` to ``solar_azimuth`` in :py:func:`~pvlib.tracking.singleaxis`. 

  aparent_azimuth should be apparent_azimuth
• We had a new contributor in 7caf4eb
  This account got deleted, so I leave it up to you whether or not to include him in the list of contributors.
• I'm hesitant about so many :py:func:`~...` -> especially in Line 9:

  * Deprecate :py:func:`~pvlib.modelchain.get_orientation`. (:pull:`2495`) 

  There are at least two other implementations (methods pvlib.pvsystem.FixedMount.get_orientation and pvlib.pvsystem.SingleAxisTrackerMount.get_orientation) with the same identifier. I also think that if I, as a user, were reading the changelog, I'd find it useful to know exactly what submodule we are talking about, so if the function name does not ring a bell for me, at least know if the features are being used in my scripts.

Feel free to do whatever you want, this is plain nitpicking.

oops...
I understand it wouldn't block the release, but this is an easy fix. Happy to do it today. Two options:

1. add these to the glossary, but this might take longer while we agree on the wording of definitions
2. remove :term: for these variables

For a nice clean release, I could open a PR for 2) and then for the 0.13.2 release we could get these added to the glossary and reinstate the link. A bit of undo/redo, but I don't think that's a problem just in case 1) takes longer than expected. What do you think?

Thanks @echedey-ls for those points, and good work finding that missing contributor!

@RDaxini I opted to do your option (2) here in this PR for the sake of expediency.

Thanks @kandersolar! 🎉
