+### Known Issues
+- DIAG_MANAGER: 3D diurnal diagnostic variables are not supported in this version of FMS
+### Added
+- FMS2_IO: Documentation was added for FMS2_io to help users convert from fms_io/mpp_io
+### Changed
+- FMS2_IO: The error messages in FMS2_io were updated to give more useful information
+- TEST_FMS: The unit tests in mosaic, axis_utils, and time_interp_external were updated to use the FMS2_io version of these routines and are no longer skipped
+- DOCS: The doxygen generated documentation has been improved with more doxygen comments added and a more cohesive layout
+- TEST_FMS: Unit tests for time_manager were updated to use the new get/set_date_gregorian routines
+### Removed
+- MPP_IO: The namelist variable use_mpp_io was removed from interpolator, amip_interp, diag_manager, topography, xgrid, and data_override
+- MPP_IO: Any remaining fms_io/mpp_io calls from the source and test code were removed
+- FMS: Removes the hardcoded path for input.nml, path now may be specified in the call to `fms_init`
+### Fixed
+- MPP: Fixes algorithm used with nested grid updates to properly coalesce x-dir and y-dir pelists for vector quantities
+- CMAKE/AUTOTOOLS: Fixes for minor issues with filenames in both the CMake and autotools build systems
+- MPP: Restored deleted pset functionality needed by GFDL SCM by reinstating mpp_pset.F90
+- MPP: Fixed uninitialized variables for data domains in mpp domains broadcast routines
+- MPP: Minor memory leaks from deallocating domains
+- AXIS_UTILS: Fix PGI related error with string length sizes

 ## [2021.02] - 2021-05-20
 ### Added
 - FMS2_IO: Added fms2_io support for boundary condition restarts. `register_restart_region_2d` and `register_restart_region_3d` were added to fms2_io’s `register_restart_field` interface and `read_restart_bc` and `write_restart_bc` subroutines were added to read and write boundary conditions restarts. See [test_fms/fms2_io/test_bc_restart.F90](https://github.com/NOAA-GFDL/FMS/blob/9d55115a331685e4c6e01f2dfb3b770a9f80fa37/test_fms/fms2_io/test_bc_restart.F90) for sample usage.
