Hello all,

We are pleased to announce the netCDF-C 4.6.0 release. Highlighted changes
from the 4.5.0 release are as follows:

   - [Enhancement] Full support for using HDF5 dynamic filters, both for
   reading and writing. See the file *docs/filters.md <http://filters.md>*.
   - [Enhancement] Reversed a handful of 4.5.0 changes which enforced
   documented-yet-previously-unenforced specifications, as these broke long
   established workflows.
   - [Enhancement] Added an option to enable strict null-byte padding for
   headers; this padding was specified in the spec but was not enforced.
   Enabling this option will allow you to check your files, as it will return
   an E_NULLPAD error. It is possible for these files to have been written by
   older versions of libnetcdf. There is no effective problem caused by this
   lack of null padding, so enabling these options is informational only. The
   options for configure and cmake are
   --enable-strict-null-byte-header-padding and
   -DENABLE_STRICT_NULL_BYTE_HEADER_PADDING, respectively. See Github #657
   <https://github.com/Unidata/netcdf-c/issues/657> for more information.
   - [Enhancement] Reverted behavior/handling of out-of-range attribute
   values to pre-4.5.0 default. See Github #512
   <https://github.com/Unidata/netcdf-c/issues/512> for more information.
   - [Bug] Fixed error in tst_parallel2.c. See Github #545
   <https://github.com/Unidata/netcdf-c/issues/545> for more information.
   - [Bug] Fixed handling of corrupt files + proper offset handling for
   hdf5 files. See Github #552
   <https://github.com/Unidata/netcdf-c/issues/552> for more information.
   - [Bug] Corrected a memory overflow in tst_h_dimscales, see Github #511
   <https://github.com/Unidata/netcdf-c/issues/511>, Github #505
   <https://github.com/Unidata/netcdf-c/issues/505>, Github #363
   <https://github.com/Unidata/netcdf-c/issues/363> and Github #244
   <https://github.com/Unidata/netcdf-c/issues/244> for more information.
