Please follow the links for a summary of the changes in each
component.<br>
</font></p>
<h1><font size="+1">Platform support</font><br>
</h1>
<ul>
<li><font size="+1">C++14 is the minimum required language
version; C++17 may be optionally used when available.</font></li>
<li><font size="+1">Microsoft Visual Studio 2017 and 2019 are now
supported.</font></li>
<li><font size="+1">LLVM 6 is now supported</font></li>
<li><font size="+1">GCC up to version 9 is supported; GCC 9 does
not currently work with C++17 builds, due to an incompatible
change in std::filesystem</font><br>
</li>
</ul>
<p></p>
<h1><font size="+1">New and updated features</font><br>
</h1>
<ul>
<li><font size="+1">Support has been added for reading and writing
OME-TIFF images with sub-resolutions (pyramids).</font></li>
<li><font size="+1">Support for handling OME-TIFF files with
missing TiffData planes has been improved.</font></li>
<li><font size="+1">Support for handling OME-TIFF files with
separate companion metadata files been improved.</font></li>
<li><font size="+1">The Boost libraries have been made optional;
some header-only Boost libraries are still required, but will
be removed in a future release.</font></li>
<ul>
<li><font size="+1">Use the CMake option </font><font size="+1"><tt>-Dfilesystem=standard|boost|qt5</tt></font><font
size="+1"> to choose between std::filesystem,
Boost.Filesystem or a Qt5-based equivalent.</font></li>
<li><font size="+1">Use the CMake option </font><font size="+1"><tt>-Doptions=boost|qt5</tt></font><font
size="+1"> to choose between Boost.ProgramOptions or Qt5
Core options handling.</font></li>
</ul>
<li><font size="+1">The Xerces-C++ and Xalan-C++ libraries have
been made optional, and can be replaced by the Qt5 Xml and
XmlPatterns libraries, respectively.</font></li>
<ul>
<li><font size="+1">Use </font><font size="+1"><tt>-Dxmldom=xerces|qt5</tt></font><font
size="+1"> to choose the XML DOM implementation.</font></li>
<li><font size="+1">In this release, XSLT transforms are only
supported with Xerces-C++ and Xalan-C++; model upgrades and
downgrades are not functional with Qt5.</font></li>
</ul>
<li><font size="+1">The OME Common XML, XSLT and units support
have been split into separate (optional) libraries, which will
be built depending upon the configuration options above.
These are named <i>ome-xerces-util</i>, <i>ome-xalan-util</i>
and <i>ome-unit-types</i>, respectively.</font></li>
</ul>
<p></p>
<h1><font size="+1">Infrastructure changes</font><br>
</h1>
<p><font size="+1">Continuous integration testing is performed on
GitLab, testing on FreeBSD, Linux, MacOS X and Windows platforms
in a number of different build configurations, including C++14
and C++17 variants, with Boost or Qt, and with Python 3 or
Python 2.<br>
</font></p>
<h1><font size="+1">Funding</font><br>
</h1>
<p><font size="+1">I would like to thank Damir Sudar and Michel
Nederlof of Quantitative Imaging Systems, LLC for funding the
completion of both the OME-TIFF sub-resolution pyramid feature,
and the work to replace Boost with Qt5. Additionally, thanks to
Olivier de Gaalon and Renato Araujo at KDAB for their
collaboration and testing of these changes.<br>
