v5.4.1

netCDF-Java

Version 5.4.1

The NetCDF-Java/Common Data Model (CDM) library version 5.4.1 release was announced on December 17th, 2020. NetCDF-Java requires Java 8 or later. This release has been built and test using AdoptOpenJDK (a.k.a. Adoptium) 8, 11, and 14, and Zulu 8 and 11.

v5.4.0?

What happened to v5.4.0? As we were wrapping up the release, we were notified by our dependency check scanner than one of the libraries we use had posted a CVE. Rather than finalizing the release using a dependency with a known vulnerability, we decided to skip v5.4.0, upgrade the impacted dependency, and move to v5.4.1.

Notices

We have been in the process of solidifying the public API for the library, and this release contains the results of those efforts. The 5.x line of development will provide both the old and new classes/methods, and you are likely to encounter deprecations when you first compile against this release. 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.
