<h2><a name="Version9.16"></a>Version 9.16 (2015-03-20)</h2>
<p>This is the twelfth full release in the stable 9.x series, and is
primarily a maintenance release.
<p> Highlights in this release include:
<ul>
<li>
<p>"LockColorants" command line option for tiffsep and psdcmyk devices. Specifying
-dLockColorants will restrict those devices to only the colorants list on the command
line (thus: -c "<< /SeparationColorNames [ /Cyan /Magenta /Yellow /Black /Violet /Orange]
/SeparationOrder [ /Cyan /Magenta /Yellow /Black /Violet /Orange]>> setpagedevice"), rather
than allowing the devices to add new colorants as encountered in the input. This is, obviously,
preferable for real printers, where only a certain of inks will be available.
</li>
<li>
<p>Improved high level devices handling of Forms. Whilst High level devices (eg pdfwrite)
already checked Forms to see if they are duplicates, and if so use the initial definition.
However, this does not improve performance, since the Form PaintProc still needs to be executed
for each instance of the Form, and the matching algorithm could, in very odd circumstances, be
defeated. The new implementation benefits both causes, meaning the second and subsequent invocation
of the form need not re-run the PaintProc, and removes the heurisic aspect of the reuse detection.
</li>
<li>
<p>New URW+ fonts in which the families NimbusMono, NimbusRoman and NimbusSans have been
augmented with production quality Greek and Cyrillic glyphs. These correspond to our
substitutes for the PDF base 14 fonts.
</li>
<li>
<p>Plus the usual round of bug fixes, compatibility changes, and incremental improvements.
</li>
</ul>
