Dear E3SM Team,
A new bug-fix release of E3SM-Unified is available: 1.9.1. E3SM-Unified is a combination conda and spack environment that includes a large amount of analysis and pre- and post-processing software for E3SM users. The new version includes updates to MOAB, NCO, zppy, and zstash packages.

Details
A few critical bugs were revealed after the release of 1.9.0 in September and these are fixed here. The new version has been deployed on our supported machines: Acme1, Andes, Anvil, Chicoma, Chrysalis, Compy, Frontier and Perlmutter. Note: We encourage users at OLCF to use Andes, rather than Frontier, for processing and analysis.
On 6 machines (Anvil, Chicoma, Chrysalis, Compy, Frontier and Perlmutter) there are 6 packages of interest -- ESMF, ILAMB, MOAB, NCO, TempestExtremes and TempestRemap -- that have been built with Spack using system compilers and MPI libraries. When you load E3SM-Unified on a compute node, you will have access to these versions, which can be run in parallel and which will typically run more efficiently than their counterparts in conda packages.
Next version
Testing of the next version (1.10.0) is planned to begin in early February 2024 and deployment is expected in early March. To request packages and versions to include, make a comment on Next Version.
As always, please email me if there are any questions, or post an issue at https://github.com/E3SM-Project/e3sm-unified/issues.
Cheers,
Xylar and the Infrastructure Team
