INTRODUCTION
This document describes the differences between this release and the previous
HDF5 release. It contains information on the platforms tested and known
problems in this release. For more details check the HISTORY*.txt files in the
HDF5 source.
Note that documentation in the links below will be updated at the time of each
final release.

Bug Fixes since HDF5-1.10.2 release
==================================
Library
-------
- Error checks in h5stat and when decoding messages
h5stat exited with seg fault/core dumped when
errors are encountered in the internal library.
Add error checks and --enable-error-stack option to h5stat.
Add range checks when decoding messages: old fill value, old
layout and refcount.
(VC - 2018/07/11, HDFFV-10333)
- If an HDF5 file contains a malformed compound datatype with a
suitably large offset, the type conversion code can run off
the end of the type conversion buffer, causing a segmentation
fault.
This issue was reported to The HDF Group as issue #CVE-2017-17507.
NOTE: The HDF5 C library cannot produce such a file. This condition
should only occur in a corrupt (or deliberately altered) file
or a file created by third-party software.
THE HDF GROUP WILL NOT FIX THIS BUG AT THIS TIME
Fixing this problem would involve updating the publicly visible
H5T_conv_t function pointer typedef and versioning the API calls
which use it. We normally only modify the public API during
major releases, so this bug will not be fixed at this time.
(DER - 2018/02/26, HDFFV-10356)
Configuration
-------------
- Moved the location of gcc attribute.
The gcc attribute(no_sanitize), named as the macro HDF_NO_UBSAN,
was located after the function name. Builds with GCC 7 did not
indicate any problem, but GCC 8 issued errors. Moved the
attribute before the function name, as required.
(ADB 2018/05/22, HDFFV-10473)
- Reworked java test suite into individual JUnit tests.
Testing the whole suite of java unit tests in a single JUnit run
made it difficult to determine actual failures when tests would fail.
Running each file set of tests individually, allows individual failures
to be diagnosed easier. A side benefit is that tests for optional components
of the library can be disabled if not configured.
(ADB 2018/05/16, HDFFV-9739)
- Converted CMake global commands ADD_DEFINITIONS and INCLUDE_DIRECTORIES
to use target_* type commands. This change modernizes the CMake usage
in the HDF5 library.
In addition, there is the intention to convert to generator expressions,
where possible. The exception is Fortran FLAGS on Windows Visual Studio.
The HDF macros TARGET_C_PROPERTIES and TARGET_FORTRAN_PROPERTIES have
been removed with this change in usage.
The additional language (C++ and Fortran) checks have also been localized
to only be checked when that language is enabled.
(ADB 2018/05/08)
- The --enable-debug/production configure flags are listed as 'deprecated'
when they should really be listed as 'removed'.
In the autotools overhaul several years ago, we removed these flags and
implemented a new --enable-build-mode= flag. This was done because we
changed the semantics of the modes and didn't want users to silently
be exposed to them. The newer system is also more flexible and us to
add other modes (like 'clean').
The --enable-debug/production flags are now listed as removed.

Known Problems
==============
At present, metadata cache images may not be generated by parallel
applications. 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.
