HDF5 version 1.8.20-snap4 currently under development
================================================================================
INTRODUCTION
============
This document describes the differences between HDF5-1.8.18 and
HDF5-1.8.19, and contains information on the platforms tested and
known problems in HDF5-1.8.19.
For more details, see the files HISTORY-1_0-1_8_0_rc3.txt
and HISTORY-1_8.txt in the release_docs/ directory of the HDF5 source.
Links to the HDF5 1.8.19 source code, documentation, and additional materials
can be found on the HDF5 web page at:
https://support.hdfgroup.org/HDF5/
The HDF5 1.8.19 release can be obtained from:
https://support.hdfgroup.org/HDF5/release/obtain518.html
User documentation for 1.8.19 can be accessed directly at this location:
https://support.hdfgroup.org/HDF5/doc1.8/
New features in the HDF5-1.8.x release series, including brief general
descriptions of some new and modified APIs, are described in the "What's New
in 1.8.0?" document:
https://support.hdfgroup.org/HDF5/doc/ADGuide/WhatsNew180.html
All new and modified APIs are listed in detail in the "HDF5 Software Changes
from Release to Release" document, in the section "Release 1.8.19 (current
release) versus Release 1.8.18
https://support.hdfgroup.org/HDF5/doc1.8/ADGuide/Changes.html

- H5DOread_chunk
Users wanted to read compressed data directly from a file without any
processing by the HDF5 data transfer pipeline, just as they were able
to write it directly to a file with H5DOwrite_chunk.
New API function, corresponding to existing function H5DOwrite_chunk.
H5DOread_chunk reads a raw data chunk directly from a chunked dataset
in the file into the application buffer, bypassing the library’s internal
data transfer pipeline, including filters.

Support for New Platforms, Languages, and Compilers
===================================================
Bug Fixes since HDF5-1.8.19
===========================
Configuration
-------------
- None
Library
-------
- Fix H5HL_offset_into()
(1) Fix H5HL_offset_into() to return error when offset exceeds heap data
block size.
(2) Fix other places in the library that call this routine to detect
error routine.
(HDFFV-10216, VC, 2017/09/05)
Parallel Library
----------------
- None
Performance
-------------
- None
Tools
-----
- h5ls
h5ls generated error on stack when it encountered a H5S_NULL
dataspace.
Adding checks for H5S_NULL before calling H5Sis_simple (located
in the h5tools_dump_mem function) fixed the issue.
(ADB - 2017/08/17, HDFFV-10188)
- h5dump
h5dump segfaulted on output of XML file.
Function that escape'd strings used the full buffer length
instead of just the length of the replacement string in a
strncpy call. Using the correct length fixed the issue.
(ADB - 2017/08/01, HDFFV-10256)
- h5diff
h5diff segfaulted on compare of a NULL variable length string.
Improved h5diff compare of strings by adding a check for
NULL strings and setting the lengths to zero.

Known Problems
==============
The dynamically loaded plugin test libraries require undefined references
to HDF5 functions to be resolved at runtime in order to function properly.
With autotools on CYGWIN this results in build errors, and we have not
found a solution that satisfies both. Therefore the dynamically loaded
plugin tests have been disabled on CYGWIN.
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.
