## Version 9.05 (2012-01-30)

This is the fifth full release in the stable 9.x series.

Highlights in this release include:

- Ghostscript's PDF interpreter is now able to make use of the DroidSansFallback TrueType font to automatically substitute for missing CIDFonts. Whilst it is always best to ensure the original CIDFont is available for the best and most accurate output, the ability to make an automatic substitution will be valuable for those merely viewing or proofing such files.

- Ghostscript now supports "unmanaged color transformations" for source DeviceXXX colors (in other words, they use a simple conversion, rather than the ICC profile based color workflow). This is beneficial in uses where performance takes precedence over ultimate color fidelity (the command line parameter -dUseFastColor enables this).

- The font set distributed with Ghostscript has been changed to the standard 35 Postscript-compatible fonts distributed by URW.

- Ghostscript now includes a simple ink-coverage device, contributed by Sebastian Kapfer (inkconv).

- The TIFF, JPEG and PNG output devices now support embedding of the device ICC profile in the output file.

- Ghostscript now ships modified OpenJPEG sources for JPEG2000 decoding (replacing JasPer - although JasPer is still included for this release). Performance, reliability and memory use whilst decoding JPX streams are all improved

- jbig2dec now has simple halftone region support

- The ps2write device has had a large number of output quality and stability improvements.
