 ## [2023.03] - 2023-10-27
 ### Known Issues
 - GCC 9 and below as well as GCC 11.1.0 are unsupported due to compilation issues. See prior releases for more details.
-- `NO_QUAD_PRECISION` macro is no longer set by FMS, the `ENABLE_QUAD_PRECISION` macro has replaced prior usage of `NO_QUAD_PRECISION`. `-DENABLE_QUAD_PRECISION` should be set if quad precision is to be used, otherwise FMS will not use quad precision reals.
+- `NO_QUAD_PRECISION` macro is no longer set by FMS, the `ENABLE_QUAD_PRECISION` macro has replaced prior usage of `NO_QUAD_PRECISION`. `-DENABLE_QUAD_PRECISION` should be set if quad precision is to be used, otherwise FMS will not use quad precision reals where applicable.
 
 ### Added
 - UNIT_TESTS: New unit tests have been created or and existing ones expanded on for any modules utilizing mixed precision support.
 
 ### Changed
-- MIXED PRECISION: Most directories in FMS have been updated to accept both 4 byte and 8 byte reals as input for public interfaces and routines. This deprecates the `--enable-mixed-mode` option, which enabled similar functionality but was limited to certain directories and was not enabled by default. To facilitate easier testing of these code changes, the CMake precision options for default real size were left in (along with an equivalent `--disable-r8-default` flag for autotools). The resulting libraries will support both real kinds regardless of default real size. It should also be noted that many routines that accept real arguments have been moved to include files along with headers in order to be compiled with both kinds.
+- MIXED PRECISION: Most subroutines and functions in FMS have been updated to simultaneously accept both 4 byte and 8 byte reals as arguments. This deprecates the `--enable-mixed-mode` option, which enabled similar functionality but was limited to certain directories and was not enabled by default. To facilitate easier testing of these code changes, the CMake precision options for default real size were left in (along with an equivalent `--disable-r8-default` flag for autotools). The resulting libraries will support mixed-precision real kinds regardless of default real size. It should also be noted that many routines that accept real arguments have been moved to include files along with headers in order to be compiled with both kinds. Most module level variables were explicitly declared as r8_kind for these updates.
 - Some type/module changes were made to facilitate mixed precision support. They are **intended** to have minimal impact to other codebases:
   - COUPLER_TYPES: In coupler_types.F90,  `coupler_nd_field_type` and `coupler_nd_values_type` have been renamed to indicate real kind value: `coupler_nd_real4/8_field_type` and `coupler_nd_real4/8_values_type`. The `bc` field within `coupler_nd_bc_type` was modified to use r8_kind within the value and field types, and an additional field added `bc_r4` to use r4_kind values.
   - TRIDIAGONAL: Module state between r4 and r8 calls are distinct (ie. subsequent calls will only be affected by calls of the same precision). This behaviour can be changed via the `save_both_kinds` optional argument to `tri_invert`.
