What's Changed

toolsUI

A special v5.9.1.1 toolsUI only release contains a critical update for the application to address an issue that prevented startup. Please see the v5.9.1.1 release page for toolsUI downloads.

Major bug fix

This bug was introduced during the development of 5.6.1 (may be present in 5.6.1-SNAPSHOTs), and is present in releases v5.7.0 up to v5.9.1. This bug triggers a runtime error in a critical part of the codebase (VariableDS) in multithreaded environments. Here is an example of a stacktrace that is generated when the bug is triggered:

Notice Minimum Java version for netCDF-Java Notice

Currently, the netCDF-Java project targets version 8 of the JVM. We are looking to get a feel for the minimum version required by the community, as support for Java 8 begins to dwindle for 3rd party dependencies that the project relies upon. Please consider participating in our GitHub poll. Thank you to those who have voted!

Features/enhancements:

Notable bug fixes:

Build changes

The version of gradle used to build the project was upgraded during this release cycle to support building with JDK 21. The upgrade required an upgrade to the shadow plugin, which builds the uber jars, such as toolsUI.jar and netcdfAll.jar. The new shadow plugin creates the jar files under build/distributions/ (previously they were created under build/libs/).

v5.5.2

netCDF-Java

Version 5.5.2

The NetCDF-Java/Common Data Model (CDM) library version 5.5.2 release was announced on January 5th, 2022. NetCDF-Java requires Java 8 or later. This release has been built and tested using Temurin 8 from the (Eclipse Adoptium project) 8, 11, and Zulu 8 and 11.

Notices

The previous release, 5.5.1, although tested on Java versions 8 and 11, was compiled with Java 11, and caused errors for some users running JDK 8. This release addresses those compatibility issues, and was compiled using Temurin 8.
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.
