Next release (2026.04.002)

[dougiesquire]

Changes for the next release of ACCESS-ESM1.6. I haven't set the version yet because I'm not 100% on what will be included.

Currently includes:

• Update to MOM5 2026.02.001
  • Includes corrections to some diagnostics' units, and fixes for compiling with GCC
  • This was intended to be done in the previous release but was accidentally removed
• Update to FMS 2025.08.001
  • Added control of date stamp formatting in diagnostic filenames
• Update to UM7 2026.04.002
  • gfortran related fixes for UM 2025

🚀 Attempted to deploy access-esm1p6 Prerelease pr218-1 with commit e6eae45

🖥️ Gadi Deployment ✔️

Usage Instructions

access-esm1.6, defined in spack.yaml, will be deployed to Gadi as:

• 2026.04.001 as a Release (when merged).
• pr218-1 as a Prerelease (during this PR).

This Prerelease is accessible on Gadi using:

module use /g/data/vk83/prerelease/modules
module load access-esm1p6/pr218-1

When using the above modules, the binaries shall be on your $PATH.

For advanced users, this Prerelease is also accessible on Gadi via /g/data/vk83/prerelease/apps/spack/1.1/spack in the access-esm1p6-pr218-1 environment.
Due to inode-saving measures, one will have to manually untar the environment metadata before environment activation with tar -xf .spack-env .spack-env.tar. It will require one to have write privileges.

Configuration Information

This Prerelease is deployed using:

• access-nri/spack on branch 1.1
• ACCESS-NRI/upstream-spack-packages version access/v1.1
• access-nri/access-spack-packages version 2026.08.007
• access-nri/spack-config version 2026.08.001

If the above was not what was expected, commit changes to the manifest in this PR, or propose changes to build-cds config/settings.json.

I've just checked with @anton-seaice and @MartinDix - once the new UM version is in it sounds like there aren't any further changes at the moment, and this one should be ready to go!

[dougiesquire]

@blimlim, I think um7@2026.04.002 needs to be added to the spack package?

[blimlim]

Oh my bad I missed that step, I'll add that now

[dougiesquire]

All good - happy to review
