Version 9.05 of Ghostscript
Release Notes: The PDF interpreter now can make use of the DroidSansFallback TrueType font to automatically substitute for missing CIDFonts. Support for "unmanaged color transformations" (with the command line option "-dUseFastColor") for source DeviceXXX colors was added. A simple ink-coverage device is now included. The TIFF, JPEG, and PNG output devices now support embedding of the device ICC profile. Optimized OpenJPEG sources (for JPEG2000 decoding) are now included in the distribution. jbig2dec gained simple halftone region support. The ps2write device gained output quality and stability improvements.

The ps2write device gained output quality and stability improvements.
Release Notes: Flexibility for controlling color based upon the graphic object type was introduced. New tiffscaled8, tiffscaled24, and pngmonod devices were added. Downscaling is now supported for png16m and pnggray. The PDF interpreter now tries continue interpreting a PDF after encountering an error in a stream. x11alpha was re-enabled as the default device on Unix systems, now that compatibility problems between anti-aliased output and transparency are resolved. A new experimental text output/extraction device was introduced. The XFonts functionality was removed. Source revision control was moved to Git.
Release Notes: A new halftone technique for sampled image data was introduced for monochrome devices, avoiding performance problems with the existing implementation. Further performance, memory use, and stability improvements were made for recently introduced features. Unix/Linux build fixes and various other bug fixes were made.
Release Notes: A new, robust CFF parser was implemented in C, replacing the previous PostScript one. The tiffscaled device was added, which renders internally as tiffgray, but then downsamples by an integer scale factor and error diffuses to 1bpp output. DSC compatible output was added to ps2write. A number of performance, memory use, and stability improvements with the new features introduced in 9.00 were made, plus the usual bug fixes.
Release Notes: This release includes a move to an ICC-based color rendering workflow. The second major change in this release is that glyph rendering for all font types except Type 3 is now handled by Freetype (via a much improved and enhanced Font API).
