The following intermediate ESMF libraries are planned to be removed on the UFS Tier-1 platforms.

8_1_0_beta_snapshot_27        8_1_0_beta_snapshot_36        8_1_0_beta_snapshot_47        
8_1_0_beta_snapshot_27-debug  8_1_0_beta_snapshot_36-debug  8_1_0_beta_snapshot_47-debug  

For developers who are using those ESMF versions, please merge your branches to use a later version of ESMF library that are available. Currently the develop ufs-weather-model branch is using the ESMF public release 8_2_0. Please create an issue in the ufs-weather-model repository if you have any concerns/questions.

Recently two changes on NEMS driver cleanup (PR#533) and the fv3-jedi coupling (#586) were committed to the ufs-weather-model develop branch. Due to these changes, an updated NUOPC field dictionary file "fd_nems.yaml" is now required for all the ufs-weather-model application runs. This file is currently located in ufs-weather-model/tests/parm/fd_nems.yaml in the  ufs-weather-model repository. Please copy this file to your run directory when you update model code with the latest ufs-weather-model develop branch.

Another minor change is that the configuration variable "cpl" in model_configure file was removed in PR#586, having it in model_configure does not impact the model run, but we recommend removing it from the model_configure when you sync code with the latest develop branch.

PR#534 was merged to the ufs-weather-model repository to speed up compiling the model executable. The FMS submodule has been moved out of the ufs-weather-model repository, it is built as a library and used as a prebuilt library in ufs-weather-model build system. This code update significantly reduced the compile time in many UFS applications.

Developers are encouraged to merge their branches to the top develop branch to take advantage of this new feature. Currently the FMS library is available on the tier-1 UFS supported platforms. Developers using these systems should be able to build the model after the merge without additional code changes. Developers using other platforms will need to build the FMS library before building the model executable.
