 * Fix of --enable-benchmark benchmark tests [Github #1211](https://github.com/Unidata/netcdf-c/issues/1211)
 * Update the license from the home-brewed NetCDF license to the standard 3-Clause BSD License.  This change does not result in any new restrictions; it is merely the adoption of a standard, well-known and well-understood license in place of the historic NetCDF license written at Unidata.  This is part of a broader push by Unidata to adopt modern, standardized licensing.
-* [BugFix] Corrected DAP-releated issues on big-endian machines. See [Github #1321](https://github.com/Unidata/netcdf-c/issues/1321), [Github #1302](https://github.com/Unidata/netcdf-c/issues/1302) for more information.
