 * We've added API support to take advantage of ZStandard compression functionality, [as described here](https://github.com/Unidata/netcdf-c/issues/2173).  Note that you can suppress this with the new options `--disable-zstandard-plugin` (for `configure`) and `-DDISABLE_ZSTANDARD_PLUGIN` (for `cmake`).
