## netCDF-Java API Changes (5.10.x)
## netCDF-Java Changes (5.10.x)

Point release notes:
* [5.10.0](https://github.com/Unidata/netcdf-java/releases/tag/v5.10.0){:target="_blank"} (_yyyy-mm-dd, unreleased_)
* [5.10.0](https://github.com/Unidata/netcdf-java/releases/tag/v5.10.0){:target="_blank"} (_2026-06-24_)

Starting with 5.10.0, the netCDF-Java library requires Java 17 to build (although the build will produce Java 8 bytecode, so the minimum supported version is still Java 8).
Note: we are looking to update the minimum version of the JVM we support for the project.
Please consider taking a moment to participate in the [poll on GitHub](https://github.com/Unidata/netcdf-java/discussions/1468){:target="_blank"}.

The 5.10.0 release adds support for reading blosc compressed data using the C-Blosc2 native library.
The new artifact for JNA support is `edu.ucar.unidata:libblosc2-jna` (the current version is `{{ site.cblosc2_version }}`).
The new artifact for JNA support is `edu.ucar.unidata:libblosc2-jna`.
The jar containing native libraries for C-Blosc2 is `edu.ucar.unidata:libblosc2-native:2.23.1.0` (v2.23.1 of C-Blosc2).
Additionally, version 1.1.7.0 of the `libaec-native` artifact is available (v1.1.7 of libaec).
More information regarding the use of the native jars can be found in the [using netCDF-java artifacts documentation](using_netcdf_java_artifacts.html#native-compression-code).

The 5.10.x release extends support for GRIB1 and GRIB2 feature collections against by object storage.
Much of the infrastructure backing other types of feature collections has also been extended to work against object storage.
If GRIB index files exist in the object store, they will be used.
If they do not exist, they will be created in the local cdm cache (default location is `~/.unidata/cache/`).

For users of our uber jars (i.e. `netcdfAll`, `ncIdv`, `toolsUI`), we now produce Software Bill of Materials (SBOMs) following the CycloneDX standard (driven by the OWASP Foundation).
These SBOMs detail all the dependencies included in the uber jars, including the transitive dependencies.
The SBOMs are available on the [Unidata downloads site](https://downloads.unidata.ucar.edu/netcdf-java/){target="_blank"} as well as the [GitHub release page](https://github.com/Unidata/netcdf-java/releases){target="_blank"}.

Full release notes, including a list of bug fixes and updated 3rd party dependencies, can be found on the [GitHub release page](https://github.com/Unidata/netcdf-java/releases){target="_blank"}.
