ghostscript-agpl: updated to 9.55.0

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).

Log message:
ghostscript-agpl: updated to 9.54.0

The 9.54.0 release is a maintenance release, and also adds new functionality.

Highlights in this release include:

Overprint simulation is now available to all output devices, allowing quality \ 
previewing/proofing of PostScript and PDF jobs that rely on overprint. See the \ 
-dOverprint option documentation in: Overprint

The "docxwrite" device adds the ability to output to Microsoft Word \ 
"docx" format. See: docxwrite

The pdfwrite device is now capable of using the Tesseract OCR engine when it is \ 
built into Ghostscript to improve searchability and copy and paste functionality \ 
when the input lacks the metadata for that purpose. See: UseOCR

Ghostscript/GhostPDL now includes a "map text to black" function, \ 
where text drawn by an input job (except when drawn using a Type 3 font) can be \ 
forced to draw in solid black. See: BlackText

Ghostscript/GhostPDL now supports simple N-up imposition "internally". \ 
See: NupControl

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.

ghostscript-agpl: updated to 9.53.3

9.53.3:
A crash (or silent, erroneous exit) on 64 bit Windows and other LLP64 type \ 
environments.
What appears to be a compiler optimiser bug in 64 bit Windows builds with Visual \ 
Studio 2019
A crash related to management of ICC profile objects
A crash on SPARC hardware due to an alignment mismatch in the bitmap cache
A parameter type mismatch that would cause Ghostcript to error out during \ 
initialisation, which affected 64 big, big endian architectures.
An expected side effect of another change that prevented multithreaded rendering \ 
and background rendering from working correctly.

ghostscript-agpl: Update to 9.53.2

Changelog:
Version 9.53.2 (2020-09-25)

Highlights in this release include:

    The 9.53.2 release is primarily maintenance.

    Three issues arose with 9.53.0/1 that prompted the release of
    a .2 patch:

	A crash (or silent, erroneous exit) on 64 bit Windows and
	other LLP64 type environments.

	A parameter type mismatch that would cause Ghostcript to
	error out during initialisation, which affected 64 big,
	big endian architectures.

	An expected side effect of another change that prevented
	multithreaded rendering and background rendering from
	working correctly.

    Details of those can be found in the changelog.

    The most obvious change is the (re-)introduction of the patch
    level to the version number, this helps facilitate a revised
    policy on handling security related issues.

    To clarify: in the event we decide to release a patch revision,
    it will replace the release with the previous patch number.
    Release notes, highlights and warnings will remain the same,
    except for the addition of whatever fix(es) prompted the patch.

    Our efforts in code hygiene and maintainability continue.

    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).

    Due to some patches to the Tesseract sources that are required
    (integrated upstream, but awaiting release), time constraints,
    and the experimental nature of the feature, we only support
    including Tesseract from source, not linking to Tesseract shared
    libraries. Whether we add this capability will be largely
    dependant on community demand for the feature.

    See Enabling OCR for more details.

    We have added Python bindings for the gsapi interface, can be
    found in demos/python. These are experimental, and we welcome
    feedback from interested developers.

    For those integrating Ghostscript/GhostPDL via the gsapi
    interface, we have added new capabilities to that, specifically
    in terms of setting and interrogating device parameters. These,
    along with the existing interface calls, are documented in:
    Ghostscript Interpreter API

    IMPORTANT: In consultation with a representative of (OpenPrinting)
    it is our intention to deprecate and, in the not distant future,
    remove the OpenPrinting Vector/Raster Printer Drivers (that
    is, the opvp and oprp devices).

    If you rely on either of these devices, please get in touch
    with us, so we can discuss your use case, and revise our plans
    accordingly.

    IMPORTANT: We have forked LittleCMS2 into LittleCMS2mt (the
    "mt" indicating "multi-thread"). LCMS2 is not thread safe and
    cannot be made thread safe without breaking the ABI. Our fork
    will be thread safe and include performance enhancements (these
    changes have all be been offered and rejected upstream). We
    will maintain compatibility between Ghostscript and LCMS2 for
    a time, but not in perpetuity. If there is sufficient interest,
    our fork will be available as its own package separately from
    Ghostscript (and MuPDF).

    The usual round of bug fixes, compatibility changes, and
    incremental improvements.
