Version 9.02 of Ghostscript
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.
Other releases
Release Notes: This release changes to the AGPL, improves thread safety, produces "Direct Web View" PDFs directly, extends the Font API to support PCL/PXL and XPS as well as Postscript/PDF, adds new options adding flexibility to the color management workflow, and adds a BigTIFF output option.
Release Notes: PDF/A-2 support was added to the pdfwrite output device. Suport was added to pdfwrite to be run in "server mode" and for the "%d" format in the OutputFile switch, for writing individual files. The output created by ps2write was modified to support the deficiencies in a range of recent PostScript devices. Support for large numbers of separations was improved for the tiffsep* devices, resolving "unencodable pixels" errors. The devices tiffsep, psdcmyk, and psdrgb gained "downscaler" support. Many other bugfixes, compatibility changes, and incremental improvements were made.
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.
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.
