    oss-fuzz 52133 "graphicsmagick:coder\_ICB\_fuzzer:
    Heap-buffer-overflow in ReadBlob".

2022-10-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - scripts/changelog2rst.sh: Try to deal with the crazy mix of

    generate the HTML documentation.

2022-09-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

    it to execute Python scripts. This avoids depending on a default
    name.

  - magick/common.h (MAGICK\_FUNC\_MALLOC\_2ARG): Add macros to support
    GCC malloc attributes which accept arguments.

2022-09-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

    directly since this seems to be prefered over converting from
    ".bin" files.

2022-08-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - Makefile.am: Some people prefer GPG signature files in ASCII
    armored ".asc" format rather than the OpenPGP binary ".bin"
    format, so produce both.

2022-08-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - Fix UTF-8 encoding errors in some text and source files.  A few
    more issues remain.  Assistance is appreciated.

  - coders/heif.c: If module is compiled, but HasHEIF is not
    defined, then RegisterHEIFImage/UnregisterHEIFImage
    implementations are empty.

  - coders/jxl.c: If module is compiled, but HasJXL is not defined,
    then RegisterJXLImage/UnregisterJXLImage implementations are
    empty.

2022-05-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - Magick++/lib/Image.cpp: colorMapSize() method for returning the
    number of colormap entries should be a const method.  Change is
    due to an email from Miro Kropáček on May 29, 2022.

2022-05-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - www/Magick++/Image.rst: Update getIndexes() and
    getConstIndexes() documention to mention that the selected region
    is defined by a prior getPixels(), getConstPixels(), or
    setPixels() call.  This is inspired by private email from Miro
    Kropáček on May 8, 2022.

  - coders/jpeg.c (WriteJPEGImage): Change "arithmetic" to
    "arithmetic-coding" in order to match ImageMagick's previously
    existing syntax.

  - coders/png.c (ReadOnePNGImage): Assure that entire image list is
    freed. Addresses oss-fuzz 46997 "graphicsmagick:coder\_MNG\_fuzzer:
    Indirect-leak in MagickMallocCleared".  This is a new issue due to
    incrementally seeking the complete correct error-handling cleanup.

2022-05-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

    particular event will be logged.  Us this as much as possible
    throughout the software to replace use of IsEventLogging().

  - coders/png.c (ReadMNGImage): Address oss-fuzz 46913
    "graphicsmagick:coder\_WPG\_fuzzer: Indirect-leak in
    MagickMallocCleared" which was partially pre-existing and
    partially due to a botched fix for oss-fuzz 46843.

2022-04-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/png.c (ReadMNGImage): Address oss-fuzz 46843

2022-04-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/{msl.c, svg.c, url.c}: When \_\_MINGW32\_\_ is defined, then
    only define \_MSC\_VER if it is not already defined.  Also define
    \_MSC\_VER with a somewhat useful value.  This change is prompted by
    a posting by "LM" to the graphicsmagick-core list on April 17,
    2022.

2022-04-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

2022-04-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - magick/blob.c (OpenBlob): Allocate setvbuf() buffer externally
    rather than implicitly.  I am hoping that the several oss-fuzz
    reports about using uninitalized memory from glibc's
    \_IO\_file\_doallocate() go away.

2022-04-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

    or modulo by float zero (DIVIDE\_BY\_ZERO)".
    (ReadJP2Image): Fix Coverity 376911 "Improper use of negative
    value (NEGATIVE\_RETURNS)".

  - coders/jxl.c (ReadJXLImage): Added patch from Tobias Mark to

    default.

2022-03-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/jxl.c (WriteJXLImage): Call JxlEncoderCloseInput() so
    that encoder output is not corrupt.  JXL passes testsuite tests
    now!

  - magick/command.c (CompareImageCommand): Add -auto-orient support
    to 'compare'.  This tries to assure that the two images are right
    side up before comparing.

  - coders/jxl.c (WriteJXLImage): Work to update JXL writer code to

2022-02-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/heif.c (ReadHEIFImage): Pass decode options to

    monitor support but leave it disabled since libheif does not
    currently invoke the callbacks.

  - coders/jpeg.c (ReadJPEGImage): Store embedded profiles in image,
    even if in 'ping' mode.  This addresses a problem discovered when
    interfacing with minimagick (Debian bug #1006374 "graphicsmagick
    breaks ruby-mini-magick").

  - coders/url.c (ReadURLImage): Deal with libxml2 not offering HTTP
    or FTP capabilities.  It seems that support for FTP has now been
    removed by default.

2022-02-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - README.txt: Recomend using JasPer 3.0.0 (or later).

  - coders/jp2.c (ReadJP2Image): Jasper 3.0.0 hid the functions we
    were using so switch back to using jas\_image\_decode(), but in a
    more secure way than before.

2022-01-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - www/download.rst: Document how to retrieve the PGP signing key
    from a key server.

2022-01-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/jp2.c (ReadJP2Image): Always use
    ThrowJP2ReaderException().  Should address oss-fuzz Issue 43979:
    "graphicsmagick:enhance\_fuzzer: ASSERT: jas\_get\_ctx() ==
    jas\_global.ctx".

2022-01-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

2022-01-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/miff.c (ReadMIFFImage): Do not proceed to next image in
    sequence unless the character read is the expected 'i' character.
    Inspired by GraphicsMagick bug #659 "Can not escape $0 in a batch
    command".

  - coders/heif.c (ReadHEIFImage): Take row stride into account when
    reading pixel rows. Add support for 'ping' mode.  Add header magic
    detection.  Add module aliases.  Add useful traces.

2022-01-15  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

  - coders/jxl.c: Added preliminary JPEG XL support written by
