Hello all,
The Unidata netCDF team is happy to announce the first release candidate
for netCDF-C v4.6.2. If no new bugs or issues are reported we expect to
have the full release within the next week or so. This is primarily, but
not completely, a maintenance and bug fix release, although there are a
number of under-the-hood enhancements. Fortran and C++ interface releases
will follow. Thank you to all of our many contributors, and of particular
note, thanks to Ed Hartnett for a number of HPC-related improvements.
Fortran and C++ interface releases will follow.

The changes from the previous version include (but are not limited to):
- [Enhancement] Create a new version of _NCProperties provenance
attribute. This version (version 2) supports arbitrary key-value pairs. It
is the default when new files are created. Version 1 continues to be
accepted.
- [Enhancement] Allow user to set http read buffersize for DAP2 and DAP4
using the tag HTTP.READ.BUFFERSIZE in the .daprc file.
- [Enhancement] Allow user to set http keepalive for DAP2 and DAP4 using
the tag HTTP.KEEPALIVE in the .daprc file (see the OPeNDAP documentation
for details).
- [Enhancement] Support DAP4 remote tests using a new remote test server
locatedon the Unidata JetStream project.
- [Enhancement] Improved the performance of the nc_get/put_vars
operations by using the equivalent slab capabilities of hdf5. Result is a
significant speedup of these operations. See GitHub #1001
<https://github.com/Unidata/netcdf-c/pull/1001> for more information.
- [Enhancement] Expanded the capabilities of NC_INMEMORY to support
writing and accessing the final modified memory. See GitHub #879
<https://github.com/Unidata/netcdf-c/pull/879> for more information.
- [Enhancement] Made CDF5 support enabled by default. See Github #931
<https://github.com/Unidata/netcdf-c/issues/931> for more information.
- [Bug Fix] Corrected a number of memory issues identified in
ncgen. See GitHub
#558 for more information <https://github.com/Unidata/netcdf-c/pull/558>.
