+## [2021.01] - 2021-03-08
+### Added
+- MPP: A counter for timers to report how many times a timer section is run
+- MPP: Adds missing interfaces to be consistent with interfaces that use the OVERLOAD and no_8byte_integer macros in order to allow building without MPI
+- MPP: Extends interfaces for read and write routines to include 32-bit and 64-bit real data arrays
+- MPP: Adds unit tests for mpp and mpp_io for all public routines with mixed-precision interfaces and expands on existing tests for mixed-precision
+- Adds an .editorconfig file with the project's preferred editor configuration
+- A variable MODDIR in configure.ac for use in Makefiles to find required Fortran module files
+- Adds FMS description web page as a markdown file
+### Changed
+- DOCS: Updates various modules to doxygen style comments and makes adjustments to correctly generate doxygen documentation through the build system
+- PLATFORM: changes usage of platform.h to platform_mod and it's associated data types
+- Changes all previous uses of flush subroutine calls to function calls
+- Changes travis CI to Github actions CI and removed all trailing whitespace
+### Removed

+- MPP: Fixed a bug causing mpp_get_UG_domain_tile_pe_inf to seg fault from the incorrect assignment of an optional argument
+- FMS: Fixes issues with FMS unit tests failing from pointer allocations by reworking deallocate_unstruct_pass_type 
+- MPP_IO: Fixes unintentional printing of file attributes
+- An issue with the automake build system causing unnecessary rebuilds of source files
+- Fixes CMake build of the FMS library to install configuration files in the appropriate directories; and for OpenMP dependencies to the private
