+Originator(s): glemieux (Gregory Lemieux, LBNL, [email protected])
+Date: Sun Mar  2 15:27:01 PST 2025
+One-line Summary: FATES parameter file switch migration
+
+Purpose and description of changes
+----------------------------------
+
+Move global FATES switches from the FATES parameter file to the namelist.
+
+
+Significant changes to scientifically-supported configurations
+--------------------------------------------------------------
+
+Does this tag change answers significantly for any of the following physics configurations?
+(Details of any changes will be given in the "Answer changes" section below.)
+
+    [Put an [X] in the box for any configuration with significant answer changes.]
+
+[ ] clm6_0
+
+[ ] clm5_0
+
+[ ] ctsm5_0-nwp
+
+[ ] clm4_5
+
+Notes of particular relevance for users
+---------------------------------------
+
+Changes to CTSM's user interface (e.g., new/renamed XML or namelist variables):
+
+The following FATES namelist options are now available:
+   - use_fates_daylength_factor
+   - fates_photosynth_acclimation
+   - fates_stomatal_model
+   - fates_stomatal_assimilation
+   - fates_leafresp_model
+   - fates_cstarvation_model
+   - fates_regeneration_model
+   - fates_hydro_solver
+   - fates_radiation_model
+
+The following FATES namelist option is available, but not yet implemented in FATES:
+   - fates_electron_transport_model
+
+Notes of particular relevance for developers:
+---------------------------------------------
+Changes to tests or testing:
+
+The FATES two stream tests no longer generation a FATES NetCDF parameter file on-the-fly.
+The need to do so is removed as the fates_radiation_model option is controlled by the
+namelist.
+
+
+Testing summary:
+----------------

+  build-namelist tests (if CLMBuildNamelist.pm has changed):
