        * coders/pdf.c (WritePDFImage): Converting a TIF to a PDF set the
        page MediaBox to the TIFF dimensions in pixels while the CropBox
        is set in local context dimensions. The latter is correct, the
        former is not.  Set the MediaBox to the proper dimension in local
        context.  Should be the same in this context.  Patch by Hubert
        Figuiere and retrieved from SourceForge patch #64 "Incorrect
        MediaBox in PDF export".

        * magick/pixel_cache.c: Memory cache implementation of pixel cache
        now uses resource limited memory allocator.  It was previously
        resource limited, but by using the resource allocation APIs
        directly.

        * coders/tiff.c: Remove unintended double-charging for memory
        resource.  Remove explicit memset where possible.

        * coders/gif.c (ReadGIFImage): Fix memory leak of global_colormap
        if realloc of memory for comment fails.  Fixes oss-fuzz 29316
        "Direct-leak in MagickMalloc".

        * coders/meta.c (ReadMETAImage): Fix double-free if blob buffer
        was reallocated after being attached to blob.  Fixes oss-fuzz
        29193 "Heap-double-free in MagickFree".

        * configure.ac: Updates to use recommended forms of AC_INIT and
        AM_INIT_AUTOMAKE.  This was/is painful due to how development
        snapshot versioning is handled.  The version string produced for
        the snapshot version will now contain the snapshot date.  Effort
        has been made to avoid other impacts due to AC_INIT's enforcements
        for how version information is used.

2021-01-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * PerlMagick/Magick.xs: Remove GCC warnings which spewed out at
        increased warning levels.

        * magick/magick_types.h.in: Hide definitions not intended for the
        rest of the world under "if defined(MAGICK_IMPLEMENTATION)".

2021-01-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * configure.ac: Skip library symbol tests for gdi32 since these
        fail with the MSYS2 w64-i686 compiler and well as i686 Cygwin.
        The failures caused a build regression for i686 MSYS2/Cygwin.

        * Copyright.txt: Copyright year updates and ChangeLog rotation for
        the new year.
