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: https://github.com/Unidata/netcdf-c/releases/v4.5.0-rc1 - Release Candidate Documentation: http://www.unidata.ucar.edu/software/netcdf/docs_rc/ - Windows installer downloads: http://www.unidata.ucar.edu/software/netcdf/docs_rc/winbin.html 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! -Ward Ward Fisher wfisher@xxxxxxxx UCAR/Unidata - Software Engineer Release Notes 4.5.0-rc1 - June 5, 2017 - [Enhancement] DAP4 is now included.
