## Version 9.15 (2014-09-22)

This is the eleventh full release in the stable 9.x series, and is primarily a maintenance release.

Highlights in this release include:

- 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.

  For further information on the new pdfwrite color management, see: Color Conversion and Management

- Plus the usual round of bug fixes, compatibility changes, and incremental improvements.
