@aidanheerdegen, @blimlim are you okay with me also updatingspack-packages here? There have been a number of updates to ACCESS-ESM1.5 component packages, mostly relaxing version restrictions by the looks of things.

Yep, but as it's more than just the WOMBAT code change we would normally run a repro test. However @blimlim and I had a chat and agreed that regardless if this changes the specific answers or not in the repro test the major version should be bumped because the WOMBAT code change will modify results for any simulation which had ocean temps exceeding 35 degrees.

Would you agree @dougiesquire?

Would you agree @dougiesquire?

I would

[blimlim]

I've just added in the CICE error code changes. Should we change the version number to 2025.04.000?

[dougiesquire]

Should we change the version number to 2025.04.000?

We had a similar discussion here. In that issue we decided to increment the minor version because (to use @aidanheerdegen's words) "the model is ostensibly unchanged but there are minor updates". I think that's also the case here?

I guess one benefit of 2025.04.000 is to move to the "new" versioning scheme

[dougiesquire]

@blimlim, could you please add the CICE change to the PR description

[blimlim]

@blimlim, could you please add the CICE change to the #31 (comment)

Can do, added in!

"the model is ostensibly unchanged but there are minor updates". I think that's also the case here?

Good question, I'm not 100% sure what's best here. I think from the earlier discussion here, we were thinking about bumping the major version though am happy either way if we expect the changes to not effect the model in a major way.

[dougiesquire]

I think from the earlier discussion here, we were thinking about bumping the major version though am happy either way if we expect the changes to not effect the model in a major way.

Oh, I thought that discussion was about the config version. @aidanheerdegen can you set us straight

[blimlim]

Oh, I thought that discussion was about the config version

Good point, you might be right. Admittedly I'm not too clear on the guidelines for config versions vs model versions.

[dougiesquire]

I think [email protected] makes sense here. This really is a very minor update. For the majority of users, the only change will be the CICE error output.

@blimlim would you be able to review?

[dougiesquire]

We could go 2024.12.001 but it feels odd to me to change the syntax without changing the date

Thanks @dougiesquire, looks good to me!

[aidanheerdegen]

Why is every time a special case!? :)

Ugh.

Use 2024.12.1.

And yes the previous discussion about reproducibility was about the config version.
