+### Fixed
+- SHARED: Fixes crashes due to uninitialized namelist variables.
+
+### Changed
+- Routines/variables from FMS have been updated to include a prefixes containing fms and the subdirectory/module name. This was necessitated by aliases being added to the 'global' libFMS.F90 module in FMS.
+- FULL: Adds logic for PE assignment in order to allow for a data atmosphere to be used alongside the combined ice-ocean driver.
+
+### Removed
+- Usage of fms_io and mpp_io has been deprecated. If using these modules in a model, you must compile both FMS and FMScoupler with the -Duse_deprecated_io CPP flag.
