v5.4.2
netCDF-Java
Version 5.4.2
The NetCDF-Java/Common Data Model (CDM) library version 5.4.2 release was announced on August 27th, 2021. NetCDF-Java requires Java 8 or later. This release has been built and test using Temurin 8 from the (Eclipse Adoptium project) 8, 11, and Zulu 8 and 11.
Notices
Our intention is to continue to provide support for v5.x as long as we are able to maintain Java 8 compatibility, which is dependent on upstream library support for providing security releases that do not require moving to Java 11. The next major version of netCDF-Java (v6.x) will continue to provide Java 8 support, but will only provide the new API. A high-level roadmap for the library can be found on the project wiki.
