 #### Changes
 
+* [Bug Fix] Fix some race conditions due to use of a common file in multiple shell scripts . See [Github #2552](https://github.com/Unidata/netcdf-c/pull/2552).
 * [Enhancement][Documentation] Add Plugins Quick Start Guide.  See [GitHub #2524](https://github.com/Unidata/netcdf-c/pull/2524) for more information.
 * [Enhancement] Add new entries in `netcdf_meta.h`, `NC_HAS_BLOSC` and `NC_HAS_BZ2`. See [Github #2511](https://github.com/Unidata/netcdf-c/issues/2511) and [Github #2512](https://github.com/Unidata/netcdf-c/issues/2512) for more information.
 * [Enhancement] Add new options to `nc-config`: `--has-multifilters`, `--has-stdfilters`, `--has-quantize`, `--plugindir`.  See [Github #2509](https://github.com/Unidata/netcdf-c/pull/2509) for more information.
