Bug Fixes and Optimizations
</para>

<para>
Performance fix: optimize page merging operation to avoid
unnecessary open/close calls on files being merged. This
solves a dramatic slow-down that was observed when merging
certain types of files.

<para>
Optimize how memory was used for the TIFF predictor,
drastically improving performance and memory usage for files
containing high-resolution images compressed with Flate
using the TIFF predictor.

Add new class <classname>QPDFSystemError</classname>, derived
from <classname>std::runtime_error</classname>, which is now
thrown by <function>QUtil::throw_system_error</function>.
This enables the triggering <classname>errno</classname>
value to be retrieved.

<para>
Add <function>ClosedFileInputSource::stayOpen</function>
method, enabling a
<classname>ClosedFileInputSource</classname> to stay open
during manually indicated periods of high activity, thus
reducing the overhead of frequent open/close operations.

Build Changes

<listitem>
<para>
For the mingw builds, change the name of the DLL import
library from <filename>libqpdf.a</filename> to
<filename>libqpdf.dll.a</filename> to more accurately
reflect that it is an import library rather than a static
library. This potentially clears the way for supporting a
static library in the future, though presently, the qpdf
Windows build only builds the DLL and executables.
