NetCDF 4.6.3

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.

Detailed information about the release is available in the Release Notes.
