🔆 Executive Summary: HDF5 Version 2.2.0
Important
- An RPM package is not provided for this release of HDF5 as an issue with the package was found during testing. The HDF Group is investigating alternative packaging methods for future releases.
Performance Enhancements:
-
Added an I/O block cache to the ROS3 VFD to reduce the number of requests to S3 for files not using paged allocation
-
Improved the performance of several tools (h5dump, h5ls, h5diff, h5repack, h5stat and h5format_convert) for specific file structures where many objects are linked to with multiple hard links
Significant Advancements:
Enhanced Features:
- Made several improvements to the CMake logic for handling filter libraries
Java Enhancements:
- Java dependency JAR paths are now configurable CMake cache variables, allowing system-provided JARs to be used in place of the bundled copies.
Acknowledgements:
We would like to thank the many HDF5 community members who contributed to this release of HDF5.
