- New version
- Remove all patches
- Update spec
- Security fixes:
  + Fixes for CERT security alert TA04-217A described at
    "http://www.us-cert.gov/cas/techalerts/TA04-217A.html".
  + AVI, BMP, & DIB security fixes.
  + PSD security fixes.
  + P7 format security fix.
  + Fix EXIF IFD stack overflow vulnerability.
  + SGI security fix for RLE encoding (CVE-2006-4144)
  + XCF security fix (CVE-2006-3743)
  + PALM heap overflow fix (CVE-2006-5456)
  + DCM security fix (CVE-2006-5456)
  + Fix for shell command injection in delegate code via file names)
    (CVE-2005-4601).  Delegate execution is much more secure now.
  + Don't use filenames as printf specifications (CVE-2006-0082).
  + Fix integer overflow in DCM coder (CVE-2007-1797).
  + XWD integer overflow fix (CVE-2007-1797).
  + Implementation has replaced usage of strcpy, strcat, and strncat
    with the more security conscious strlcat and strlcpy.
  + DCM, DIB, XCF, XBM, and XWD security fix for integer overflow
    vulnerability (IDefense 09.19.07).
  + Do not access X11 or invoke convenience or stealth delegate programs
    based on the file extension. In particular, these file extensions are
    rejected for consideration as a format specifier: 'autotrace',
    'browse', 'dcraw', 'edit', 'gs-color', 'gs-color+alpha', 'gs-gray',
    'gs-mono', 'launch', 'mpeg-encode', 'print', 'scan', 'show', 'win',
    'xc', and 'x'.
- Bug fixes:
  + Ghostscript sometimes displays an error message and fails, yet it
    returns a success error code to GraphicsMagick. Verify that
    Ghostscript has updated the output file before attempting to use it.
  + Fixed a configure script syntax error when testing for trio.
  + When requesting a list of formats, all of the modules in the module
    search path are considered. Previously only the modules in the same
    directory as the LOGO module were listed.
  + Ensure that an image clip mask is respected by the negate algorithm.
  + The BMP writer was sometimes writing incorrect BMP v4 files.
  + Support reading and writing large PCX files.
  + Fixed a bug which could cause possible truncation while cloning the
    image cache.
  + Ensure that MIFF files indicate the compression which was actually used.
  + Properly handle errors from libtiff so that corrupted images are not
    output.
  + Fix for stripped-TIFF reader. Discard extra samples beyond alpha in
    scanline TIFFs.
  + Endian option now controls TIFF byte-order rather than bit-order.
  + TIFF writer can now write to pipes and other non-seekable output
    destinations.
  + JBIG writer was writing empty files for some libjbig releases.
  + Improved handling of corrupt GIF files.
  + Handle large SUN format images.
  + Properly compute image depth for 16-bit SGI image files.
  + For the gmdisplay program, ensure that only RGB data is sent to Windows.
  + Many memory leak fixes.
  + PDF writer is fixed so that Ghoscript 8.5 doesn't warn about the output.
  + PDF writer now writes proper output with CCITT compression.
  + Properly use fseeko() and ftello() if they are available.
  + Fixed a infinite loop bug in the XWD reader.
  + Fix minor memory leak in ProfileImage().
  + Fixed -level command parsing when a percent symbol is supplied within the
    argument rather than at the end.
  + Fix pixel scaling problem caused by floating point
    rounding error (noticed under AIX).
  + Fixed a memory leak in the GIF coder in the error return path.
  + Fix for SourceForge bug id 1353744 "MagickGetQuantumDepth doesn't work".
  + Fix for SourceForge bug id 1315109 "segfault in InitializeMagick(NULL)".
  + Fix for SourceForge bug id 1391421 "problem doing resize on 273x1 JPEG".
  + Fix for SourceForge bug id 1510075 "Failed to write PDF with JPEG compression".
  + Fix for SourceForge bug id 1572357 "GetOnePixel definition appears incorrect".
  + Fix for SourceForge bug id 1576616 Fix includedir variable in pkg-config files".
  + Fix for SourceForge bug id 1173713 "segfault in ModifyCache".
  + Fix for SourceForge bug id 1431805 "clip art wpg files cause access violation
    in graphics magick".
  + Fix for SourceForge bug id 1743141 "Affine matrix option parsing".
  + Fix for SourceForge bug id 1625477 "Memory leak reading layered PSD Image".
  + Fix for SourceForge bug id 1878992 "literal square brackets in file
    name cause large delay and bug id 1783209 "converting runs slowly
    when subimage is specified".
  + Fix for SourceForge bug id 1883527 "compression of tiff-file has no effect".
  + Successfully read files in the form "file[123]".
  + Fix reading 12-bit grayscale JPEG.
  + Set image depth appropriately when importing image from X11 display.
  + Fix map resource tracking.
  + Fix reading recent variants of ImageMagick's MIFF format.
  + Output bilevel TIFF meeting the TIFF Class F specification.
- New Utilities:
  + A 'benchmark' subcommand is now available to benchmark the
    performance of any other arbitrary subcommand (e.g. 'convert').
- Feature improvements:
  + LZW compression is now enabled by default.
  + Support industry-standard subsampling notation like "4:2:2".
  + If gm is executed under a traditional alternate name (e.g.
    convert), it will invoke the appropriate sub-command. This allows
    use of hard links, symbolic links, or just copying 'gm' to the
    desired sub-command name in order to achieve 100% ImageMagick 5.5.2
    utility compatibility.
  + Provide the --enable-magick-compat option when configuring to install
    ImageMagick utilities compatibility links.
  + Identify -verbose output includes normalized (0.0-1.0) statistics.
  + Identify and convert now print "pixels per second" rates to help
    evaluate performance.
  + Added the identify +ping option to force reading the complete file.
  + The display program now supports the +progress option to disable any
    visual progress indication (and hourglass cursor) while loading images.
  + Support writing grayscale TGA files.
  + Provide explicit support for Rec 601 and Rec 709 grayscale spaces.
  + Include some support for a log RGB space based on the 2.048 density
    range as defined for the Cineon Digital Film System.
  + Added utilities command-line support for industry standard subsampling
    notation like 4:4:4 and 4:2:2.
  + Use MAGICK_IOBUF_SIZE to tune the size of the I/O buffer.
  + Use -type Bilevel, Grayscale, TrueColor, or TrueColorMatte to
    influence the type of image that Ghostscript returns.
  + Use '-define tiff:fill-order={msb2lsb|lsb2msb}' to control TIFF bit
    fill order.
  + The -version option now dumps a feature list as well as the build
    options.
  + The -endian option now supports the option 'native'.
  + A -monitor is added to enable progress monitoring for the command line
    utilities.
  + Use the -output-directory option to 'mogrify' to send output files to
    the specified directory.
  + Use the -create-directories option in conjunction with
    -output-directory and 'mogrify' to create any necessary subdirectories.
  + A Pixels resource limit is added.  Use '-limit Pixels value' to limit
    the maximum number of pixels in an image to 'value'.
  + The already supported option '-type Optimize' is now honored by
    formats that need to choose a subformat based on the properties of
    the image. Grueling tests of many/all pixels are not performed
    unless '-type Optimize' is supplied.
  + Added a a -set option to the composite, convert, display, mogrify,
    import commands in order to allow setting an image attribute.
  + Display utility no longer defaults to reading from standard input if
    stdin is not a tty.
  + May now be configured to use the umem memory allocation library
    available in Solaris 9, Update 3 and later, or from the portable umem
    project.
- Coder additions/improvements:
  + Replaced existing DPX "support" with all-new DPX support conforming
    to the SMPTE 268M-2003 standard.
  + Cineon reader completely rewritten.
  + TIFF coder is completely re-written. Now supports reading and
    writing RGB, CMYK, and grayscale, scanline-oriented TIFF images
    with arbitrary (1 to 32 bits) depth. Includes support for tiled
    TIFF, floating point TIFF, LogLuv TIFF, BigTIFF, arbitrary depths,
    and associated alpha.
  + TIFF coder now supports retrieving and saving XMP profiles.
  + MATLAB support is much improved and supports writing as well.
  + WPG reader now supports CTM translations.
  + ART format now supports writing.
  + Support 32-bit raw RGB images.
  + Support 32-bit raw CMYK images.
  + Support 32-bit raw gray images.
  + JP2 coder reads images in YCbCr colorspace and retrieves an embedded
    ICC ICM color profile if present.
- Performance improvments:
  + The DispatchImage() and ConstituteImage() functions incorporate
    special case code for BGR, BGRO, BGRP, RGB, RGBO, and I formats (8
    bit only) in order to improve performance dramatically.
  + When writing very large JPEG images, don't enable Huffman compression
    since doing so requires libjpeg to buffer the entire image in memory.
  + When using the 'identify' -verbose option, -verbose must be specified
    twice in order to obtain the color count.  This makes normal use of
    -verbose much faster.
  + Significantly improved read/write speed for bilevel and gray images.
  + TIFF I/O is considerably faster.
  + Postscript writer is 10-15X faster.
  + PNM formats writer is 10-100X faster.
  + Rotate by 90 or 270 degrees is 2-9X faster.
