The Unidata THREDDS Development Team released version 5.4.2 of the netCDF-Java/Common Data Model (CDM) library on August 27th, 2020. The 5.4.2 includes various bug fixes, dependency upgrades (some related to security), build/doc infrastructure changes, and updates/improvements to GRIB reading capabilities.

The Unidata THREDDS Development Team released version 5.4.1 of the netCDF-Java/Common Data Model (CDM) library on December 17th, 2020. The 5.4.1 release includes the first look at the public API, support for building with Java 11 - 14, and support for accessing data from object storage, such as AWS S3.

The Unidata THREDDS Development Team released updated versions of the THREDDS Data Server (TDS) and netCDF-Java/Common Data Model (CDM) library on June 17, 2020. In addition to feature enhancements, these releases contain a variety of updates to third-party libraries, including security updates. They also address a problem in previous versions that could lead to data returned by some NetcdfSubsetService (NCSS) requests being corrupted. While the circumstances under which the problem occurs are very specific (and rare), because the possibility of data corruption exists the development team strongly recommends these upgrades to anyone using netCDF-Java/CDM or TDS. TDS administrators who are not able to upgrade immediately should disable the NetcdfSubsetService until it is possible to do so.

The netCDF-Java ucar.nc2.util.DiskCache2 class method for generating unique file names is capable of producing identical names if called in quick succession. While the circumstances under which the problem occurs are very specific (and rare), because the possibility of data corruption exists the development team strongly recommends that anyone using netCDF-Java/CDM or TDS upgrade immediately.

Netcdf-Java version 5.3.2 is now available, and includes several bug fixes, 3rd party dependency updates, and more steps towards the creation of a public API, as well as new capability for reading CDM datasets stored in any AWS S3 API compatible object store.
