* "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.
* 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.
* 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.
* Plus the usual round of bug fixes, compatibility changes, and incremental improvements.
Ghostscript now supports the PDF security handler revision 6.
The pdfwrite and ps2write (and related) devices can now be forced to "flatten" glyphs into "basic" marking operations (rather than writing fonts to the output), by giving the -dNoOutputFonts command line option (defaults to "false")
PostScript programs can now use get_params or get_param to determine if a page contains color markings by reading the pageneutralcolor state from the device (so whether the page is "color" or "mono").
Note that this is only accurate when in clist mode, so -dMaxBitmap=0 and -dGrayDetection=true should both be used.
The pdfwrite device now supports Link annotations with GoTo and GoToR actions
The pdfwrite device now supports BMC/BDC/EMC pdfmarks
Regarding the new color management for the pdfwrite device introduced in the previous release, the proscription on using the new color management when producing PDF/A-1 compliant files is now lifted.
To reiterate, also, with the new color management implementation, using the UseCIEColor option is strongly discouraged.

like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
pdfwrite now uses the same color management engine as Ghostscript rendering devices (by default LCMS2). This provides much better control over color conversion and color management generally, but will result in some small color differences when compared to the old system.
It is no longer necessary to specify UseCIEColor (and we very much encourage you not to do this) or the ProcessColorModel if you want to convert a PDF file to a specific color space, simply set the ColorConversionStrategy appropriately.
We do not expect any major problems to arise with this new code, but for the duration of this release a new switch -dPDFUseOldCMS is available which will restore the old color management. See: Color Conversion and Management
Please note that due to constraints of the PDF/A-1 specification, the new color management does not yet apply when producing PDF/A files.
A new device 'eps2write' has been added which allows for the creation of EPS files using the ps2write device instead of the old (deprecated and removed) pswrite device. This produces considerably better quality EPS files than the old epswrite device which is now also deprecated and will be removed in a future release.
ps2write now has a feature to allow customisation of the output for specific devices. Please see PSDocOptions and PSPageOptions described in ps2ps2.htm Additional Distiller Params
Ghostscript now reduces memory usage when processing PDF files that use transparency and output is to display devices such as Windows display or x11 (i.e. devices that are strictly full framebuffer devices), and to high level vector devices that cannot reproduce the PDF transparency model, such as the ps2write device or pdfwrite when 'flattening' to PDF 1.3 or earlier (-dCompatibilityLevel=1.3). This uses banding (clist) files to render the transparent areas in bands to reduce memory use, and unlike the existing page level banding, this is hidden from the target device.
Ghostscript can now collect information for pages in temp files (in Ghostscript's clist format), then render and output pages for the job in arbitrary order, including normal, reverse, odd, even, or any order or subset of the pages. This is controlled with the --saved-page=___ option. (Note that this only applies to rendering devices, and not high level devices such as pdfwrite and ps2write.) See: Deferred Page Rendering
The Ghostscript device architecture has been extended so that, when rendering bands into multiple threads, it is now possible to perform post-processing in multiple threads, such as downscale, post-render halftoning, or compression. Previously, post processing was only possible in the single main thread. This can improve performance significantly.
Ghostscript has a new "pwgraster" output device for PWG Raster output
The CUPS device now has improved support for PPD-less printing
Plus the usual round of bug fixes, compatibility changes, and incremental improvements.
Upstream removed cups support and created a new "cups-filter" package
instead. Since then, building ghostscript-agpl with the cups option
has failed. This commit removes the cups option, and should result in
zero changes to packages built without the cups option, and hence does
not PKGREVISION++.
There is still some cups configure code, which is forced off (as it
was without the option). It's not clear if this configure code should
also be removed (by upstream), or if it's a separate bit of cups
functionality. Addressing this issue and adding a cups-filter package
is left for future work, after the branch.
* Background printing (BGPrint) is a new feature allowing an accumulated page clist to be rendered by one or more rendering threads whilst the interpreter (in the "main" thread) continues to accumulate the subsequent page's clist. For certain classes of file this can result in a useful performance increase.
* GrayDetection allows suitably written devices to detect "color" input in near neutral tones (i.e. near monochrome) and to convert "on-the-fly" to pure grayscale, whilst retaining the ability to print full color on demand. This is primarily aimed at workflows where saving ink (especially color inks) is required.
* LittleCMS2 and libpng have both been updated to the latest versions.
* Support has been added to build the Ghostscript DLL for WinRT for x86, x64 and ARM (Requires MS Visual Studio 2012 Pro).
* Processing of Windows command line arguments into UTF8 (as presaged a few releases ago) has been enhanced and enabled by default.
* The URW Postscript font set has been updated to the latest version, fixing many compatibility problems with the Adobe fonts.

new enough for pango.
While doing that, also bump freetype2 dependency to current pkgsrc
version.

a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
