HDF5 version 1.10.0-alpha0 released on 2015-12-29
================================================================================
INTRODUCTION
This document describes the differences between HDF5-1.8.* and
HDF5 1.10.0-alpha0 release, and contains information on the platforms
tested and known problems in HDF5-1.10.0-alpha0.
Links to HDF5 1.10.0-alpha* source code can be found on The HDF Group's
development FTP server at the following location:

User documentation be accessed directly at this location:

New Features
============
This alpha0 release supports the following new features:
Library:
--------
- Concurrent access to HDF5 file - Single Writer/ Multple Reader (SWMR)
The Single Writer/ Multiple Reader or SWMR feature enables users to read
data concurrently while writing it. Communications between the processes
and file locking are not required. The processes can run on the same or on different platforms,
as long as they share a common file system that is POSIX compliant.
For more information, see the Single-Writer/Multiple-Reader (SWMR) Documentation at
https://www.hdfgroup.org/HDF5/docNewFeatures/NewFeaturesSwmrDocs.html
- Virtual Dataset (VDS)
The VDS feature enables data to be accessed across HDF5 files using standard HDF5 objects
such as groups and datasets without rewriting or rearranging the data. An HDF5 virtual
dataset (VDS) is an HDF5 dataset that is composed of source HDF5 datasets in a predefined
mapping. VDS can be used with the SWMR feature. For documentation check
https://www.hdfgroup.org/HDF5/docNewFeatures/NewFeaturesSwmrDocs.html
- Persistent Free File Space Tracking
Usage patterns when working with an HDF5 file sometimes result in wasted space within
the file. This can also impair access times when working with the resulting files.
The new file space management feature provides strategies for managing space in a file
to improve performance in both of these areas. For more information see
http://www.hdfgroup.org/HDF5/docNewFeatures/NewFeaturesFileSpaceMgmtDocs.html
Tools:
------
- h5watch
Allows users to output new records appended to a dataset iunder SWMR access as it grows.
The functionality is similar to the Unix user command "tail" with the follow option, which
outputs appended data as the file grows.
For more information see
http://www.hdfgroup.org/HDF5/docNewFeatures/NewFeaturesSwmrDocs.html#Tools
- h5format_convert
The tool allows users to convert the indexing type of a chunked dataset made with
a 1.10.x version of the HDF5 library when the latest file format is used to the 1.8.x
version 1 B-tree indexing type. For example, datasets created using SWMR access, can be converted
to be accessed by the HDF5 1.18 library and tools. The tools doesn't rewrite raw data, but
HDF5 metadata only.
High-Level APIs:
------
- H5DOappend
The function appends data to a dataset along a specified dimension.
Other important changes:
-----------------------
hid_t type was changed from 32-bit to a 64-bit value.
Documentation
-------------
See http://www.hdfgroup.org/HDF5/docNewFeatures/NewFeaturesSwmrDocs.html#Tools
