3.6.0
  - No change from 3.6.0RC2

3.6.0RC2
- Fixes:
  * Remove deprecated message from Imagick::roundCorners()
- Added:
  * Imagick::addNoiseImageWithAttenuate()

3.6.0RC1
  - Imagick::getImageInterlaceScheme is undeprecated. It's the appropriate function to call to get the image interlace setting.
  - Image formats are now normalised to lower case.
  - Imagick::getImageIndex and Imagick::setImageIndex are undeprecated and work on ImageMagick 7. They call MagickGetIteratorIndex and MagickSetIteratorIndex internally.
  - Imagick::averageImages is undeprecated. For IM 7 it now calls EvaluateImages(wand->images,MeanEvaluateOperator).
  - Imagick::flattenImages is undeprecated. For IM 7 it now calls MagickMergeImageLayers(intern->magick_wand, FlattenLayer); internally.
  - Imagick::getImageSize is undeprecated. For IM 7 it now calls MagickGetImageLength internally.
  - Imagick::roundCornersImage is undeprecated and available on IM7.
- Fixes:
  * Imagick::borderImage() changed internally to use OverCompositeOp rather than AtopCompositeOp for ImageMagick > 7. If you need the old behaviour, please use Imagick::borderImageWithComposite() instead, which allows you to set the composite method.
  * Imagick::frameImage() changed internally to use OverCompositeOp rather than AtopCompositeOp for ImageMagick > 7. If you need the old behaviour, please use Imagick::frameImageWithComposite() instead, which allows you to set the composite method.
  * Imagick::profileImage() fixed to allow null as second paramter again. If you can't upgrade to this version yet, pass in "", which has the same effect.
  * Imagick::ALPHACHANNEL_COPY and Imagick::ALPHACHANNEL_OPAQUE should be available on IM7.
  * Imagick::setImageMatteColor() should be available on IM7.
- Added:
  * Imagick::borderImageWithComposite() same as Imagick::borderImage() but allows user to set composite operator used.
  * Imagick::frameImageWithComposite() same as Imagick::frameImage() but allows user to set composite operator used.
  * function Imagick::cannyEdgeImage
  * function Imagick::setSeed
  * function Imagick::waveletDenoiseImage
  * function Imagick::meanShiftImage

3.5.1
  - No change from 3.5.1RC1

3.5.1RC1
  - Better detection of appropriate OpenMP library to use, i.e. GCC or Clang.

3.5.0
 - Correct parameter for ImagickPixel::getColorValue and ImagickPixel::setIndex.

3.5.0RC2
 - Fix incorrect parameter defaults, and small fixes on arginfo generation.

3.5.0RC1
- ImageMagick 7 is still not widely available on systems. So contrary to previous plans, ImageMagick 6 support will continue for now, but users are recommended to use ImageMagick 7 if possible.
- Method names have been changed to not be all lower case. Both method names and parameter information is built from the Imagick*.stub.php files.
- Prevent accidental creation of zero dimension images. ImageMagick doesn't prevent creation of zero dimension images, but will give an error when that image is used. I don't think this will affect any correctly program, but if it does, and you need to re-enable zero dimension images, please open an issue at https://phpimagick.com/issues
- Various pieces of work have been done to make GOMP not segfault including:
  * Call omp_pause_resource_all when available during shutdown.
  * Added the 'imagick.shutdown_sleep_count' (default 10) and 'imagick.set_single_thread' (default On). Both of these exist to mitigate the segaults on shutdown.
- Fixes:
  * Correct version check to make RemoveAlphaChannel and FlattenAlphaChannel be available when using Imagick with ImageMagick version 6.7.8-x
  * Imagick::morphology now no longer ignores channel parameter
- Added:

3.4.0
  No changes from 3.4.0RC6.

3.4.0RC6
- Added:
  * Imagick::evaluateImages(int EVALUATE_CONSTANT) : Imagick
- Fixes:
  * Imagick::setImageWhitePoint, Imagick::setImageRedPrimary, Imagick::setImageGreenPrimary,
  Imagick::setImageBluePrimary now take 3 params when compiled against IM7.
  * Imagick::getImageWhitePoint, Imagick::getImageRedPrimary, Imagick::getImageGreenPrimary,
   Imagick::getImageBluePrimary now return 3 values when compiled against IM7.

3.4.0RC5
- Added:
  * Imagick::subImageMatch() added parameters. The signature is now: 
    Imagick::subimagematch(Imagick $subimage[, array &$bestMatch[, float &similarity[, 
      float $similarity_threshold = 0[, int $metric = ]]]])
    These parameters are only used when compiled against ImageMagick 7.	
- Fixes:
  * wrong type for zend_parse_parameters.

3.4.0RC4
- Fixes:
  * Remove duplicated definitions of class constants.

3.4.0RC3
- Fixes:
  * Imagick::adaptiveResizeImage, Imagick::cropThumbnailImage Imagick::resizeImage, 
    Imagick::scaleImage, and Imagick::thumbnailImage have all had a rounding bug fixed. 
    An additional parameter has been added to each of them, 'bool $legacy'. If legacy 
    is true, the calculations are done with the small rounding bug that existed in
    Imagick before 3.4.0. If false, the calculations should produce the same results as 
    ImageMagick CLI does.
  * Imagick::colorizeImage() and Imagick::tintImage were using the wrong behaviour. 
    It is now fixed and the legacy behaviour can still be used by passing a 3rd 
    parameter of `true` to the function to indicate that the legacy behaviour is 
    desired.
  * Imagick::importImagePixels regression fixed.
  * Imagick::subImageMatch use correct error metric in IM7
- Added methods:
  * Imagick::similarityImage() which is an alias to Imagick::subImageMatch()

3.4.0RC2
- Fixes:
  * Version number in extension header.

3.4.0RC1
- Added support:
  * PHP 7
  * ImageMagick 7. Imagick can be compiled against either ImageMagick 6 or ImageMagick 7
    However it must be run with the exact same version it was compiled against. Trying
    to run Imagick with a different version of ImageMagick than it was compiled against 
    is not supported. Please see http://nextgen.imagemagick.org/script/porting.php for
    more information about ImageMagick 7.
- Minimum versions supported are now PHP >= 5.4.0 and ImageMagick >= 6.5.3-10.
    Earlier versions may continue to work, but they are no longer supported.
- Added methods:
  * Imagick::getConfigureOptions
  * Imagick::getFeatures
  * Imagick::getHDRIEnabled
  * Imagick::setImageChannelMask (IM7 only)
- Added IM7 constants:
  * Imagick::CHANNEL_READ_MASK
  * Imagick::CHANNEL_WRITE_MASK
  * Imagick::CHANNEL_META
- Fixes:
  * ImagickPixel::getColorQuantum, ImagickPixel::getColorValueQuantum and 
    ImagickPixel::setColorValueQuantum now correctly use floats when Imagick 
    was compiled against a HDRI version of ImageMagick
  * Imagick::exportImagePixels works for all storage types

3.3.0
  No changes

3.3.0RC2
- Corrected package versioning to exclude PHP7
- Correct params for Imagick::getColorValueQuantum

3.3.0RC1
- Added ImagickKernel class. These can be used with the Imagick::morphology or 
    Imagick::filter functions.
- Added methods:
  * Imagick::brightnessContrastImage()
  * Imagick::colorMatrixImage()
  * Imagick::deleteImageProperty()
  * Imagick::filter()
  * Imagick::forwardFourierTransformImage()
  * Imagick::getAntiAlias()

  * Imagick::rotationalBlurImage()
  * Imagick::selectiveBlurImage()
  * Imagick::setAntiAlias()
  * Imagick::setImageBiasQuantum()
  * Imagick::setProgressMonitor()
  * Imagick::setRegistry() - which allows setting the "temporary-path" used by ImageMagick
  * Imagick::statisticImage()
  * Imagick::subImageMatch()
  * ImagickPixel::getColorQuantum()
- Added constants:
  * Imagick::RESOURCETYPE_TIME
  * Imagick::RESOURCETYPE_THROTTLE
  * Imagick::CHANNEL_RGBA
  * Imagick::ALPHACHANNEL_BACKGROUND
  * Imagick::FUNCTION_ARCSIN
  * Imagick::FUNCTION_ARCTAN
- Fixed Imagick::clutImage() parameter parsing

  * Imagick::getImageFormat()
  * Imagick::getImageMimetype()
  * Imagick::getSamplingFactors()
  * Imagick::identifyImage()
  * Imagick::tintImage
- Fixed segfault when compiling statically
- ImagickDraw::setFontFamily no longer checks whether the font is available. This allows a 
  font family to be set where the family name is not the same as the font name. However it also
  means an invalid family name can be set, leading to the default font being used, instead of an
  exception being thrown. See https://github.com/mkoppanen/imagick/issues/77
- Removed Zend MM support
- Excluded deprecated methods:
  * Imagick::getImageMatte()
  * Imagick::colorFloodfillImage()
  * Imagick::matteFloodfillImage()

  * Imagick::paintOpaqueImage()
  * Imagick::paintTransparentImage()
  * Imagick::mapImage()

  * Imagick::getImageSize()
  * Imagick::setImageAttribute()
  * Imagick::getImageAttribute()
  * Imagick::mosaicImages()
  * Imagick::averageImages()
  * Imagick::flattenImages() 
    This is replaced by $im = $im->mergeImageLayers(\Imagick::LAYERMETHOD_FLATTEN)
  * Imagick::getImageChannelExtrema()
  * Imagick::getImageExtrema()
- Ini file changes
  * Added imagick.skip_version_check. Imagick now checks that it was compiled against the same version of
  ImageMagick that it is being run with, and will give a warning if it was compiled against a different
  version of ImageMagick. The skip_version_check setting allows you to suppress this warning. However
  it is strongly recommended to use the version of ImageMagick that Imagick was compiled against.
- Misc:
  * CI now compiles with CFLAGS="-Wno-deprecated-declarations -Wdeclaration-after-statement -Werror"

2.0.0a1 	
- Initial Release

0.9.13 	
- Fixed compile error with newer versions of GraphicsMagick and ImageMagick
- Fixed assertion when using imagick_setfillcolor
- Fixed segfault when an empty blob is loaded
- Use new API for fetching support image formats / fonts

- Fix some segfaults on errors (by Andrei Nigmatulin)
- EXPERIMENTAL support for ImageMagick >= 6.0.0 (hint by Stanislav Yadykin). Please report successes or failures.

0.9.10 	
- A ./configure change release only.
- Changed config.m4 for checking for correct ImageMagick Version.
  ImageMagick >= 5.5.3 and < 6.6.0 or GraphicsMagick >= 1.0.0 are needed.
- ImageMagick >= 6.0.0 does not work currently. Patches are welcome ;)

0.9.9 	
- added function imagick_set_image_comment() for setting the comment attribute
of an image.
- function imagick_setcompressiontype() was not setting the correct structure.
This was identified and tested by Sergio Salvatore (sergio@cucinalogica.com).
- added function imagick_transparent() for setting a particular color to be
transparent within an image.
- changed how certain errors are handled in _php_imagick_is_error() to be
less restrictive. This apparently helps fix issues with certain types
of images that otherwise appear corrupt. Thanks to Hien Duy Nguyenxi
(hdn@umich.edu) for finding this, recommending the change and testing it.
- added imagick_set_image_quality() for manipulating the quality of the
resultant image.
- added examples/set_image_quality.php for testing the
imagick_set_image_quality() function. Thanks to Derrick DeLoreno Threatt
(dthreatt@digitalcreations.net) for bringing up the need for this function
and testing it.

0.9.8 	
- fixed critical error in call to strlen() in _php_imagick_set_last_error().
I strongly recommend you upgrade.

0.9.7 	
- fixed bug in imagick_free() that would cause it to SEGFAULT everytime
it's called.
- fixed to work with versions of ImageMagick >= 5.5.7 - special thanks to
James Huston (hustonjs@itadevelopment.com) for helping make this happen.
- test compiled against ImageMagick 5.5.3, 5.5.6 and 5.5.7 with success.
- test compiled against GraphicsMagick 1.0.1 with success.

0.9.6 	
- functions added:
imagick_getcolorspace()
imagick_error()
- added a new example called transparent_1x1.html and some explanatory text.
I can think of many uses for this code.
- thanks to James Huston (hustonjs@itadevelopment.com) for suggesting
imagick_getcolorspace() and testing it out.
- added GraphicsMagick (http://www.graphicsmagick.org) support to configure
script (enable it with --with-imagick-gm)
- imagick_readimage() now returns false if ImageMagick ReadImage() fails.
- imagick_error() returns 1 string representing any errors that have occurred
on an operation. IT IS LARGELY UNTESTED! Beware! However, you can now
do things like:
$handle = imagick_readimage( "image.jpg" ) or die( imagick_error() ) ;
- fixed configure script. It honours now values returned by Magick-config.

0.9.5 	
- functions added:
imagick_newimagelist()
imagick_pushlist()
imagick_poplist()
imagick_mosaic()
imagick_setcompressiontype()
imagick_setcompressionquality()
- modified how all functions check to see if ImageMagick has been initialized.
- added a number of new examples for demonstrating how to use image lists.
- fixed bugs in _php_imagick_alloc_handle() and _php_imagick_clear_errors()
causing core dump when working with image lists. I wasn't checking to make
sure the structures I was examining were allocated.
- thanks to James Huston (hustonjs@itadevelopment.com) for suggesting
imagick_setcompressiontype() and imagick_setcompressionquality() and
testing them.
- added supporting IMAGICK_COMPRESSION_* constants for use with
imagick_setcompressiontype().
- renamed imagick_setcompression() to imagick_setcompressiontype().
(note: this was done before the new version was released so no users should
be impacted.)

0.9.4 	
- functions added:
imagick_flatten()
imagick_getmagick()
imagick_setfillopacity()
- fixed bad code in these functions:
imagick_despeckle()
imagick_edge()
imagick_emboss()
imagick_enhance()
imagick_gaussianblur()
imagick_medianfilter()
imagick_motionblur()
imagick_reducenoise()
imagick_shade()
imagick_sharpen()
imagick_spread()
imagick_unsharpmask()
- for the above functions, if call to corresponding ImageMagick
function the module would probably core dump. If it didn't the
results would be really buddy and weird.
- setfillopacity() thanks to Allen Condit, condit@isri.unlv.edu.

0.9.3 	
- functions added:
imagick_zoom()
- the difference between imagick_zoom() and imagick_resize() is
that zoom applies the blur and filter that are defined by
the image. It is a much simpler way of resizing an image.
- added imagick.dsp and modifications for compiling under Windows.
- changed all instances of le_handle to le_imagick_handle to avoid
future conflicts.

0.9.2 	
- functions added:
imagick_profile()
- created IMAGICK_PROFILE_* to support imagick_profile().
- this release is significant because of the issue with Microsoft IE
where the image's profile causes the browser to not properly render
images (you only get red X's). See this posting:
http://studio.imagemagick.org/pipermail/magick-users/2002-September/005072.html
- added this filter IMAGICK_FILTER_UNKNOWN. If the user specifies
this filter to imagick_resize(), the resize function will take
whatever filter is defined by the image.
- modified imagick_resize() to take 6th optional parameter that is
the modifier to the geometry to facility building geometries such
as 800x600+200+200! or 450x230>.
- modified imagick_scale() to take 4th optional parameter that is
the modifier to the geometry to facility building geometries such
as 800x600+200+200! or 450x230>.
- modified imagick_sample() to take 4th optional parameter that is
the modifier to the geometry to facility building geometries such
as 800x600+200+200! or 450x230>.

0.9.1 	
- functions added:
imagick_chop()
imagick_crop()
imagick_flip()
imagick_flop()
imagick_roll()
imagick_getimagedepth()
imagick_getnumbercolors()
imagick_isgrayimage()
imagick_ismonochromeimage()
imagick_isopaqueimage()
imagick_ispaletteimage()
imagick_ordereddither()
imagick_composite()
- Added IMAGICK_COMPOSITE_OP_* for use with imagick_composite().
