🔆 Executive Summary: HDF5 Version 2.2.0

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

Enhanced Features:

  • Made several improvements to the CMake logic for handling filter libraries

Java Enhancements:

  • Added CMake cache variables for configuring Java dependency JAR paths, allowing system-provided JARs to be used in place of the bundled copies
