The Unidata THREDDS Development Team is happy to announce the availability of version 5.2.0 of the NetCDF-Java/Common Data Model (CDM) library. Of particular note with the 5.2 release is the reorganization of the gradle modules used in the project, which has resulted in a change in the published maven artifacts. For details on these changes, please visit https://docs.unidata.ucar.edu/netcdf-java/5.2/userguide/upgrade_to_50.html#netcdf-java-api-changes-52x. This move is a stepping stone towards supporting the Java Platform Module System in future releases of netCDF-Java. At the very least, this change will require updating your build infrastructure to use the new cdm-core artifact instead of cdm.
For more information, including specific changes and download links, please see the full announcement on the Unidata netCDF-Java GitHub release page.
