# ACCESS-OM2 Release Update

## New configurations

ACCESS-NRI has released new versions of the global 1°, 0.25° and 0.1° physics-only configurations. The biogeochemical configurations have not been updated. Key changes in the new releases are:

**All configurations**

- Update to a new version of MOM5 that allows using ACCESS-OM2 with coupled generic-tracers, including WOMBATlite/mid.
- Update from Intel Classic to oneAPI compilers.

**1° and 0.1° configurations only**

- Fixes to the CICE grid. These fixes were already included in [version 2.0](https://forum.access-hive.org.au/t/access-om2-release-information/1602/3) of the 0.25° configurations.

Details of the releases, including a full list of changes, are here:

>
> Standard ACCESS-OM2 configurations released and supported by ACCESS-NRI - ACCESS-NRI/access-om2-configs

### What version are these released configurations?

The released configurations are version 3.0 indicating that they are **not bitwise reproducible** with their previous versions (version 2.0). Specifically, the changes to the CICE grid and compiler updates do not preserve answers.

## How do I use these releases

See the [ACCESS-Hive instructions for using the ACCESS-OM2 model](https://docs.access-hive.org.au/models/run_a_model/run_access-om2/). All non-BGC `release-*` branches in the [access-om2-configs repository](https://github.com/ACCESS-NRI/access-om2-configs) have been updated.
