The Unidata THREDDS Development Team is happy to announce that the netCDF-Java/Common Data Model (CDM) library version 5.0.0 was released on July 29th, 2019. This is a major release and includes many bug fixes, enhancements, and a variety of updates to 3rd party libraries which include security updates. For details on the major changes in this release, please visit https://docs.unidata.ucar.edu/netcdf-java/5.0/userguide/upgrade_to_50.html. The netCDF-java development team recommends this upgrade to anyone using the netCDF-Java or its associated artifacts. We also released v4.6.14, which includes security fixes, but likely does not include the bug fixes addressed here, and does not include any of the new features.
For more information, including specific changes and download links, please see the full announcement on the Unidata netCDF-Java GitHub release page.
