 ## 4.8.2 - TBD
 
+* [Enhancement] Add complete bitgroom support to NCZarr. See [Github #2197](https://github.com/Unidata/netcdf-c/pull/2197).
 * [Bug Fix] Clean up the handling of deeply nested VLEN types. Marks nc_free_vlen() and nc_free_string as deprecated in favor of ncaux_reclaim_data(). See [Github #2179(https://github.com/Unidata/netcdf-c/pull/2179).
 * [Bug Fix] Make sure that netcdf.h accurately defines the flags in the open/create mode flags. See [Github #2183](https://github.com/Unidata/netcdf-c/pull/2183).
 * [Enhancement] Improve support for msys2+mingw platform. See [Github #2171](https://github.com/Unidata/netcdf-c/pull/2171).
