HDF5 version 1.11.0 currently under development ================================================================================ INTRODUCTION This document describes the differences between HDF5-1.10.1 and HDF5 1.10.2, and contains information on the platforms tested and known problems in HDF5-1.10.1. For more details check the HISTORY*.txt files in the HDF5 source. Links to HDF5 1.10.1 source code, documentation, and additional materials can be found on The HDF5 web page at: https://support.hdfgroup.org/HDF5/ The HDF5 1.10.1 release can be obtained from: https://support.hdfgroup.org/HDF5/release/obtain5.html User documentation for the snapshot can be accessed directly at this location: https://support.hdfgroup.org/HDF5/doc/ New features in the HDF5-1.10.x release series, including brief general descriptions of some new and modified APIs, are described in the "New Features in HDF5 1.10" document: https://support.hdfgroup.org/HDF5/docNewFeatures/index.html All new and modified APIs are listed in detail in the "HDF5 Software Changes from Release to Release" document, in the section "Release 1.10.1 (current release) versus Release 1.10.0 https://support.hdfgroup.org/HDF5/doc/ADGuide/Changes.html If you have any questions or comments, please send them to the HDF Help Desk: help@hdfgroup.org CONTENTS - New Features - Support for new platforms and languages - Bug Fixes since HDF5-1.10.1 - Supported Platforms - Tested Configuration Features Summary - More Tested Platforms - Known Problems New Features ============ Configuration: ------------- - Library: -------- - Parallel Library: ----------------- - Fortran Library: ---------------- - C++ Library: ------------ - Tools: ------ - High-Level APIs: --------------- - C Packet Table API ------------------ - Internal header file -------------------- - Documentation ------------- - Support for new platforms, languages and compilers. ======================================= - Bug Fixes since HDF5-1.10.1 release ================================== Library ------- - Configuration ------------- - Performance ------------- - Fortran -------- - Tools ----- - h5import h5import crashed trying to import data from a subset of a dataset. Improved h5import by adding the SUBSET keyword. h5import understands to use the Count times the Block as the size of the dimensions. Added INPUT_B_ORDER keyword to old-style configuration files. The import from h5dump function expects the binary files to use native types (FILE '-b' option) in the binary file. (ADB - 2017/06/15, HDFFV-102191) - h5repack h5repack did not maintain the creation order flag of the root group. Improved h5repack by reading the creation order and applying the flag to the new root group. Also added arguments to set the order and index direction, which applies to the traversing of the original file, on the command line. (ADB - 2017/05/26, HDFFV-8611) - h5diff h5diff failed to account for strpad type and null terminators of char strings. Also, h5diff failed to account for string length differences and would give a different result depending on file order in the command line. Improved h5diff compare of strings and arrays by adding a check for string lengths and if the strpad was null filled.

Parallel applications can read files with metadata cache images, but since this is a collective operation, a deadlock is possible if one or more processes do not participate. Known problems in previous releases can be found in the HISTORY*.txt files in the HDF5 source. Please report any new problems found to help@hdfgroup.org.
