Hello netCDF Community,
We are pleased to announce the availability of netCDF 4.5.0 - Release
Candidate 1. There have been a number of bug fixes and improvements since
the release of 4.4.1.1; a high-level summary of changes is listed below. We
encourage everybody to give this release candidate a try pending the final
4.5.0 release. I would like to get the final release out in short order, so
the quicker we can find any lingering issues, the better!
Relevant links are as follows:
- Download the release candidate:

- Release Candidate Documentation:

- Windows installer downloads:

Thanks for your patience, we hope to have a more rapid release cycle once
more, moving forward. The next step pending the final 4.5.0 release of the
C interface is to update and release the Fortran and C++ releases.
Looking forward to any bug reports and/or issues!

Release Notes 4.5.0-rc1 - June 5, 2017
- [Enhancement] DAP4 is now included. Since dap2 is the default for
urls, dap4 must be specified by
(1) using “dap4:” as the url protocol, or
(2) appending “#protocol=dap4” to the end of the url, or
(3) appending “#dap4” to the end of the url
Note that dap4 is enabled by default but remote-testing is
disbled until the testserver situation is resolved.
- [Enhancement] The remote testing server can now be specified with the
--with-testserver option to ./configure.

more information.
- [Bug Fix] Corrected an error with how dimsizes might be read. See Github
#410 <https://github.com/unidata/netcdf-c/issues/410> for more
information.
- [Bug Fix] Corrected an issue where ‘make check’ would fail if ‘make’
or ‘make all’ had not run first. See Github #339
<https://github.com/Unidata/netcdf-c/issues/339> for more information.
