Looks good to me @schlunma! Thanks for preparing the Changelog!

Perhaps you could follow this stackoverflow answer to provide a link that allows the user to see exactly which dependencies have changed?

[schlunma]

I don't think that's worth it to be honest. Without a tag we need to mess around with commit ids and this is something I'd like to avoid 😄

If I had a dollar for everything you wanted to avoid on ESMValTool... But joking aside, I think the benefit is in being able to see what has changed between releases. Since we are adding the lock file for the first time in this release, there really is no need. Let's revisit this for the next release. Then we will also have a convenient tag.

[schlunma]

It just feels bad to add dead links in a PR (the label is only available after the release, and for the release we need the changelog...).

[schlunma]

I will do release tomorrow. We couldn't test some PRs that I would like to include into this release since Mistral had an unexpected downtime today.

• Removed scalar coordinates p0 and ptop prior to merge in multi_model_statistics #1471
• Added fix for AIRS v2.1 (obs4mips) #1472
• Remove profile_diagnostic from diagnostic settings and increase test coverage of _task.py #1404
• Added dataset and alias attributes to multi_model_statistics output #1483
