+ * Another fix for -sparse-color and unused color channels
+ * Finialize the -duplicate option created by Cristy
+
+2011-03-21 6.6.8-7 Glenn Randers-Pehrson <glennrp@image...>
+ * Revised the PNG8 encoder to use 50% threshold instead of 0% when
+ reducing transparency to binary. Collapse all resulting fully transparent
+ colors into one (the background color), to reduce the compressed filesize.
+ * First try the 4-4-4 and 3-3-3 palettes instead of 3-3-2, to preserve
+ colors (especially gray) better, when reducing to PNG8.
+
+2011-03-21 6.6.8-6 Cristy <quetzlzacatenango@image...>
+ * New version 6.6.8-6.
+
+2011-03-21 6.6.8-6 Glenn Randers-Pehrson <glennrp@image...>
+ * Re-enabled reduction of grayscale images (color-type 0) to 2 or 4 bits
+ when appropriate (reference
+ http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18098).
+ * The "-define PNG:color-type=4" option did not always force the PNG
+ encoder to write an all-opaque alpha channel (reference
+ http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18349).
+
+2011-03-14 6.6.8-6 Cristy <quetzlzacatenango@image...>
+ * Fixed memory leak for PDF and Bitmap PSD RLE support (reference
+ http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18317).
+ * Support the -statistic option: replace each pixel with corresponding
+ statistic from the neighborhood.
+ * Add support for -duplicate option.
+ * Move configuration files from /usr/share and /usr/lib to /etc and /var.
+ * Do not cache the results of fx: otherwise -format
+ '%[fx:rand()] %[fx:rand()]' returns the same random numbers.
+
+2011-03-18 6.6.8-6 Anthony Thyssen <A.Thyssen@griffith...>
+ * Replaced Minus and Divide Composition methods with Dst and Src
+ equivalents. Now users can decide how these non-commutative mathematical
+ operators are applied to the images being composited.
+ * Fix the percent escape values for %p, %n and %[fx:t], %[fx:n] to
+ respectively mean the current images index and the total number of
+ images within the current image sequence.
+
+2011-03-17 6.6.8-5 Anthony Thyssen <A.Thyssen@griffith...>
+ * Backed out the patch for Variable Blur Composition that was added
+ 2011-02-13 v6.6.7-7, until I can re-think the problem.
+ The existing fix was failing to do circular blurs correctly.
+
+2011-03-14 6.6.8-5 Glenn Randers-Pehrson <glennrp@image...>
+ * Fixed a rounding/truncation error while writing the pHYs chunk in the
+ png encoder.
+ * Don't write text-encoded profile when "-define PNG:exclude-chunk=text,ztxt"
+ is present (reference
+ http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17086 and

+ * Add support for the WebP image format.
+
+2011-03-14 6.6.8-5 Anthony Thyssen <A.Thyssen@griffith...>
+ * Ensured that -sparse-color preserves unused channels when
+ channel limited. Before this unused channels would be reset to black.
+
+2011-03-11 6.6.8-4 Glenn Randers-Pehrson <glennrp@image...>
+ * Don't try to store a bKGD chunk in a PNG8 when there are already
+ 256 colors in the palette and the background colors is not in that
+ palette (reference
+ http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18199);
+ * The "-define PNG:exclude-chunk=bKGD" option was also excluding
+ the text chunks. (reference
+ http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18253).
+
+2011-03-10 6.6.8-4 Cristy <quetzlzacatenango@image...>
+ * Fx is a mathematical function. Do not treat transparency as black.
+ * No image scene suffix for filenames that include a single bracket (reference
+ http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18267).
+
+2011-03-10 6.6.8-3 Cristy <quetzlzacatenango@image...>
+ * New version 6.6.8-3.
+
+2011-03-10 6.6.8-3 Cristy <quetzlzacatenango@image...>
+ * Boost causes an ambiguity with ssize_t when building PythonMagick. Add
+ patch from Arfrever@gento... to fix the build exception.
+
+2011-03-09 6.6.8-2 Cristy <quetzlzacatenango@image...>
+ * Support the Radiance HDR image format.
+ * Update the offset in the black channel when sharpening to avoid incorrect
+ results.
+ * Do not use GenericReadMethod for TIFF images with 64-bits per sample.
+
+2011-03-06 6.6.8-2 Glenn Randers-Pehrson <glennrp@image...>
+ * Throw error message when the requested color-type or bit-depth
+ cannot be written by the PNG encoder (error was being thrown
+ into the wrong image structure). (Reference
+ http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
+ * Don't write a PNG text chunk with "density" keyword that overrides the
+ PNG pHYs chunk, if the pHYs chunk was not excluded (reference
+ http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18253).
+ * Ignore any PNG text chunk with a "density" keyword found by the PNG
+ decoder, if the PNG datastream also contains a pHYs chunk.

+ * New version 6.6.8-1.
+
+2011-03-05 6.6.8-1 Cristy <quetzlzacatenango@image...>

+ * New version 6.6.8-0.

+2011-02-27 6.6.8-0 Cristy <quetzlzacatenango@image...>
+ * Add support for the -mode option.
+
+2011-02-27 6.6.8-0 Glenn Randers-Pehrson <glennrp@image...>
+ * Fix scaling of new color-reduction method in the PNG encoder (16-bit
+ images were scaled down to 0 or 1, or nearly black).
+ * Delay opening the PNG output blob until the PNG encoder is ready
+ to write the IHDR chunk, to avoid writing zero-length PNG files when
+ errors are found while building the palette. (reference
+ http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18162).
+
+2011-02-25 6.6.7-10 Cristy <quetzlzacatenango@image...>
+ * New version 6.6.7-10.

2011-02-23 6.6.7-10 Cristy <quetzlzacatenango@image...>
- * Return MagickEpsilon for GetResizeFilterWeight() rather than 0 (reference
- http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18132).
* Avoid seg fault in AppendImages() when one image is in the RGB colorspace
but the other is in the CMYK colorspace.
* Get rid of 'respect_parenthesis defined but not used' warnings (reference
* Add a check whether the PNG "cheap transparency" criteria are met. That
is, there is a single transparent color, no semitransparent colors, and
no opaque color that has the same RGB components as the transparent
- color. If they aren't, a color that is transparent in one pixel
- and opaque in another would always be rendered as transparent. (reference
+ color. If those aren't met, a color that is transparent in one pixel
+ and opaque in another would always be rendered as transparent, so we

of CPU time. (reference
