Version 4.6.3 of the netCDF-C library is now available. Changes include (but are not limited to):

netcdf.pc is now correctly generated either by configure or cmake. If linking against a static netcdf, you would need to pass the --static argument to pkg-config in order to list all of the downstream dependencies.
The hidden coordinates attribute is now always written, which allows faster file opens when present.
Some fixes for rename, including fix for renumbering of varids after a rename, renaming var to dim without coordinate var.
Fix of NULL parameter causing segfaults in put_vars functions.
Fix of —enable-benchmark benchmark tests.
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.
Corrected DAP-releated issues on big-endian machines.
Extended nccopy -F syntax to support multiple variables with a single invocation.
Corrected an issue where DAP2 was incorrectly converting signed bytes, resulting in an erroneous error message under some circumstances.
Modified nccopy so that _NCProperties is not copied over verbatim but is instead generated based on the version of libnetcdf used when copying the file. Additionally, _NCProperties are now displayed if/when associated with a netCDF3 file.
