Release Notes: The license is now GPLv3 or later. A large number of issues with transparency were fixed. Several significant fixes to font handling, especially when generating PDF, were made. Numerous robustness, correctness, and performance improvements were made. Security fixes addressing CVE-2009-0583 and CVE-2009-0792 were made. New generic Esc/Page devices, eplmono and eplcolor, were added, as well as the cdnj500 device to support the HP DesignJet 500. The size of PostScript integers was limited to 32 bits, as recommended in the specification.
Release Notes: Improvements were made for overprint and spot color support in documents with transparency, as well as for PDF and PS output. Proper handling of PDF-specific text rendering modes was implemented. Support for reading AES-encrypted PDF documents was added. Handling of CJK text, especially in vertical writing modes, was improved. The memory footprint with certain files at high resolutions was reduced. Several long-standing bugs in the PCL drivers with respect to duplex, resolution, and paper tray selection were fixed. Many other bugs were fixed.
Release Notes: Support for multi-threaded rendering using "-dNumRenderingThreads=n" was implemented. Images are now always interpolated in their source colorspace. Support for OpenPrinting Vector devices was upgraded to version 1.0. Two new experimental devices, a cairo output device and the svgwrite device, were added. Several robustness and performance improvements were made for large files, invalid PDF, and font handling.
Release Notes: The tiffsep device was fixed for using more than 8 colorants. Shadings, overprinting, and transparency were optimized and are substantially faster. Changes were made to prevent nearly unbounded growth in memory usage and corresponding performance problems on a few test cases. The 'pdfwrite' device was improved to fix some compatibility issues with PDF/A and to improve some font embedding and other issues. The halftone tile cache sizes and cache effectiveness were improved to help the performance when tiling with large cells or threshold arrays. Many other issues were resolved.
Release Notes: Several bugs were fixed. The default device on Unix-oriented builds was changed again to the x11alpha device, which provides antialiasing for display.
Release Notes: This release finalizes the merge with ESP Ghostscript, adding support for CUPS raster printer drivers. It also contains IJS and OpenPrinting Vector interfaces for driver plug-ins, all built-in printer drivers listed in the OpenPrinting database, X display drivers in a separate shared library, and many other improvements and bugfixes. The build process is now autotools-based. Temporarily, the GCC build defaults to the 'bbox' device instead of the 'x11' device. The GPL is also now applicable to the newest Ghostscript version, removing any functional differences between AFPL and GPL Ghostscript.
Release Notes: This release has seen a great deal of work to improve conformance with the Quality Logic PS CET suite. Where close imitation of the reference implementation is required, it now provides a 'gs_cet.ps' helper file that can be prefixed to a job to set certain optional defaults.
Release Notes: This release introduces a compressed read-only filesystem accessible from the interpreter. Support for the proprietary Luratech JBIG2 and JPEG 2000 libraries was added. Third-party libraries such as libpng, libjpeg, and zlib are now included in the source. A large number of bugs were fixed. Several rendering improvements were introduced.
Release Notes: Numerous bug fixes and improvements, particularly in the area DeviceN (spot color) handling and the PDF interpreter were implemented. The pdfwrite device can now create PDF/X-3 compliant documents using the lib/PDFX_def.ps prefix approach. A Beta version level 2 Postscript output device (ps2write) was added, which generates high-level PostScript including text and images and graphics. Rendering performance for PDF's with transparency was vastly improved (10x to 90x on files with many small transparency regions/groups).
Release Notes: This is a maintenance release which contains numerous bugfixes and improvements, particularly in the area of PDF 1.6 handling.
