* support for progressive jpegs added (fixes long standing "bug" of progressive jpegs becoming non-progressive during optimization),
* new options --all-normal & --all-progressive for converting jpegs to non-progressive & progressive,
* new -S / --size option to set target size for output file (enables lossy optimization),
Version 1.6.1beta06 [March 4, 2013]
Better documentation of unknown handling API interactions.
Corrected Android builds and corrected libpng.vers with symbol
prefixing This adds an API to set optimization options externally,
providing an alternative and general solution for the non-portable
run-time tests used by the ARM Neon code. It also makes those tests
compile and link on Android.
The order of settings vs options in pnglibconf.h is reversed to allow
settings to depend on options and options can now set (or override) the
defaults for settings.
Version 1.6.1beta07 [March 7, 2013]
Corrected simplified API default gamma for color-mapped output, added
a flag to change default. In 1.6.0 when the simplified API was used
to produce color-mapped output from an input image with no gamma
information the gamma assumed for the input could be different from
that assumed for non-color-mapped output. In particular 16-bit depth
input files were assumed to be sRGB encoded, whereas in the 'direct'
case they were assumed to have linear data. This was an error. The
fix makes the simplified API treat all input files the same way and
adds a new flag to the png_image::flags member to allow the
application/user to specify that 16-bit files contain sRGB data
rather than the default linear.
Fixed bugs in the pngpixel and makepng test programs.
Version 1.6.1beta08 [March 7, 2013]
Fixed CMakelists.txt to allow building a single variant of the library
(Claudio Bley):
Introduced a PNG_LIB_TARGETS variable that lists all activated library
targets. It is an error if this variable ends up empty, ie. you have
to build at least one library variant.
Made the *_COPY targets only depend on library targets actually being build.
Use PNG_LIB_TARGETS to unify a code path.
Changed the CREATE_SYMLINK macro to expect the full path to a file as the
first argument. When symlinking the filename component of that path is
determined and used as the link target.
Use copy_if_different in the CREATE_SYMLINK macro.
Version 1.6.1beta09 [March 13, 2013]
Eliminated two warnings from the Intel C compiler. The warnings are
technically valid, although a reasonable treatment of division would
show it to be incorrect.
Version 1.6.1rc01 [March 21, 2013]
No changes.
Version 1.6.1 [March 28, 2013]
No changes.
* GIF comments are no longer displaced by 1 for animated GIFs (reference
http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=22901).
* A blur kernel with a zero sigma is unity.
* Do not replace gAMA found in input with 1/2.2
* Avoid a libpng16 warning about storing unknown chunks.
* Improve performance when rendering a caption.
* The compare 'map' image should not be transparent.
* Use only major version for decorating include path.
February 19, 2013: Release 1.11
A GeoJSON backend was added; thanks to Christoph Hormann for
contributing this. Support for bitfields in the BMP format was
added. A minor change was made to the behavior of the alphamax
parameter; a value of 0 now gives a true polygon.

Special Issues:
Due to GCC bug 53967, several key agorithms (e.g. convolution) may execute much faster (e.g. 2-3X) for x86-64 and/or when SSE is enabled for floating point math (-mfpmath=sse) if the GCC option -frename-registers is used. Default 32-bit builds do not experience the problem since they use '387 math. It is not clear in what version of GCC this problem started but it was not noticed by the developers until the GCC 4.6 timeframe. Other compilers do not suffer from this bug.
Security Fixes:
None.
Bug fixes:
Fixed bug with format substitutions if input string ends with a single '%'.
BMP: Fixed an old bug with decoding chromaticity primaries.
PNG: Fixed reading of interlaced images. Fix reading of sub-8-bit palette and grayscale images. Some PNG sub-formats were written incorrectly. Fix crash in PNG8 writer if image colors happened to be non-zero but image was not actually colormapped.
PNG: Configure script now also searches for libpng versions 16 and 17.
TIFF: Fix a crash which was noticed when writing RGBA separated (planar) format.
--enable-symbol-prefix was not prefixing all of the C symbols. Some core C library functions were not prefixed. This option applies to the Wand library API as well now.
C API: When input is from a user-provided file descriptor, the file position is restored after reading the file header bytes. Previously the file position was rewound to the beginning of the file. This allows reading embedded image data from the current offset in a file, and allows continuing to use the stream after GraphicsMagick has returned the image.
C API: It is now possible to invoke CloseBlob() multiple times.
display: Display was supposed to respond to +/-usePixmap, but was not. It was responding to +/-use_pixmap. Now it responds to both.
Windows/VisualMagick: Fix building GraphicsMagick with Intel ICC compiler driven by Visual Studio Professional 2012.
Windows: Avoid a crash and produce a useful diagnostic if Ghostscript is needed but not yet installed.
New Features:
GM utility: New 'batch' command was contributed by Kenneth Xu which supports executing any number of other GM utility sub-commands in a single invokation in a sort of "batch" script. Input may be piped from standard input, from a specified file, or from a 'GM >' command prompt. This utilities front-end allows any other program/script to drive 'gm' using a co-process model and speeds up execution by eliminating utility start-up/shut-down time.
WIN64 (64-bit Windows): Windows 64-bit is now officially supported.
convert/mogrify: Now support -auto-orient to automatically rotate the image upright for viewing based on its current orientation setting. Also support -orient to support setting the current image orientation. Please note that the orientation property of EXIF profiles is not yet updated so the EXIF profile will be wrong after using -auto-orient.
C API: AutoOrientImage(), new New function to automatically orient the image so that it is upright for normal viewing.
Wand API: MagickGetImagePage()/MagickSetImagePage(), new functions to support getting and setting the image page size and offsets.
PNG: Added PNG48 and PNG64 support. Added PNG00 support (png encoder that inherits its color-type and bit-depth from the input, if the input was a PNG datastream).
Feature improvements:
GraphicsMagick TAP tests may now be run stand-alone using Perl's 'prove' TAP test driver.
Performance Improvements:
Detection of glob specifications in file names is more efficient.
Windows Delegate Updates:
None.
Behavior Changes:
ltdl: Libltdl is no longer bundled. Libltdl must be previously installed on the system in order to build the modules configuration.
AppendImages() now converts subsequent images to the colorspace of the first image, and no longer converts the first image to RGB. Instead, it is assumed the user knows what she is doing.
SetImageColorRegion() no longer automatically converts the image to RGB. The user is responsible for assuring that the provided color is in the same colorspace as the image.

Release 1.32_50
Repacked because of Module::Install 1.04 problems (see mail from
Miyagawa). Now Image::Info is again using good old EUMM.
* Removed plte_len stuff from the "To do" list because it is done.
* Shorten the indexed-PNG tRNS chunk length if it has more entries than the PLTE chunk.
* Bilinear resampling in C.
* Removed debugging printf.
* Set bounds correctly, add tests.
* Store pixels in uint32_t instead of long. Saves space and works
on 32-bit systems
* Bump chunky_png dependency to 1.2.7.
This is a bugfix release, with the only significant change being
changing compiler flags to work around what is probably a bug in gcc,
tending to show up on ubuntu/amd64.
Added license info for cexcept.h, libpng, and zlib.
Added consideration of "zopfli" compression to the "To do" list.
Fixed a typo that caused a cHRM chunk to be "found" if an iCCP chunk
were present.
Reset best_byte_count before trial loop.
Revise global png_set_keep_unknown_chunks() calls to avoid a libpng16
warning.
Reset "intent" to "specified_intent" before trial loop.
Reset "plte_len" to "specified_plte_len" before trial loop.
Initialize length of each trial to 0x7fffffff so any untried method
is not the "best method".
