   Version 9.55.0 (2021-09-27)
     Highlights in this release include:
       This release includes the fix for the %pipe% security issue (CVE-2021-3781).
       New PDF Interpreter: This is an entirely new implementation written in C (rather
        than PostScript, as before). For a full discussion of this change and reasons for
        it see: Changes Coming to the PDF Interpreter.
       In this (9.55.0) release, the new PDF interpreter is disabled by default in
        Ghostscript, but can be used by specifying -dNEWPDF. We hope to make it the
        default in 9.56.0, and fully deprecate the PostScript implementation shortly
        after that (depending on the feedback we get).
       This also allows us to offer a new executable (gpdf, or gpdfwin??.exe on Windows)
        which is purely for PDF input. For this release, those new binaries are not
        included in the "install" make targets, nor in the Windows installers (they will
        be from 9.56.0 onwards).
       We would ask that as many users as possible take the opportunity to test with the
        new PDF implementation (i.e. using -dNEWPDF on your gs command line), and discuss
        any problems with us, before the new implementation becomes the default.
       The pdfwrite device now supports "passthrough" for JPX/JPG2000 data images (as
        well as the already supported JPEG/DCT Encoded). That means that if no rescaling
        or color conversion of the image data is required, the encoded/compressed image
        data from the input file will be written unchanged to the output, preventing
        potential image degradation caused by decompressing and recompressing.
       The Ghostscript/GhostPDL demo apps for C, C#, Java and Python have all had
        improvements and the C#/Java/Python language bindings have now been documented,
        see Ghostscript Language Bindings
       The Zugferd compliant PDF generating definitions (lib/zugferd.ps) have been
        updated and expanded to support the current version (2.1.1) of the Zugferd spec,
        and optionally different versions of the specification.
       The PCL/m output devices now support Duplex/Tumble.
       The internal support for "n-up" style simple imposition (introduced in 9.54.0) has
        been extended and improved for better support across all input formats.
       Ghostscript now supports object specific halftone - for example, different
        halftones can be specified for text and images, reflecting the differing needs of
        rendering those two types of object.
       Our efforts in code hygiene and maintainability continue.
       The usual round of bug fixes, compatibility changes, and incremental improvements.
       (9.53.0) We have added the capability to build with the Tesseract OCR engine. In
        such a build, new devices are available (pdfocr8/pdfocr24/pdfocr32) which render
        the output file to an image, OCR that image, and output the image "wrapped" up as
        a PDF file, with the OCR generated text information included as "invisible" text
        (in PDF terms, text rendering mode 3).
       Mainly due to time constraints, we only support including Tesseract from source
        included in our release packages, and not linking to Tesseract/Leptonica shared
        libraries. Whether we add this capability will be largely dependent on community
        demand for the feature.
       See Enabling OCR for more details.

     Incompatible changes
       (9.55.0) Changes to the device API. This will affect developers and maintainers of
        Ghostscript devices. Firstly, and most importantly, the way device-specific
        "procs" are specified has been rewritten to make it (we think!) clearer and less
        confusing. See The Interface between Ghostscript and Device Drivers and The Great
        Device Rework Of 2021 for more details.
       (9.55.0) The command line options -sGraphicsICCProfile=___, -dGraphicsIntent=#,
        -dGraphicsBlackPt=#, -dGraphicsKPreserve=# have been changed to
        -sVectorICCProfile=___, -dVectorIntent=#, -dVectorBlackPt=#,
        -dVectorKPreserve=#.
     From 9.55.0 onwards, in recognition of how unwieldy very large HTML files can become
      (History9.html had reached 8.1Mb!), we intend to only include the summary
      highlights (above).
     For anyone wanting the full details of the changes in a release, we ask them to look
      at the history in our public git repository: ghostpdl-9.55.0 log.
     If this change does not draw negative feedback, History?.htm file(s) will be removed
      from the release archives.
