 Imager release history.  Older releases can be found in Changes.old
 
+ - re-work the t/200-file/400-basic.t to correctly handle failures
+   It's custom ok() function didn't have a prototype and didn't use scalar().
+   This caused ok() to use the note instead of the value being tested when
+   the method called returned an empty list.  For an example of the problem
+   caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
+
+ - remove some noise from when Imager tried to work with buggy
+   versions of giflib.
+
+ - the new autolevels filter (Imager 0.99) used an integer for the
+   sample scaling factor which caused the top output level to be too
+   low (depending on the scaling required.)  It now uses a double.
+   https://rt.cpan.org/Ticket/Display.html?id=111871
+
+ - the new autolevels filter had off-by-one errors calculating the
+   minimum and maximum luminance from the histogram.  This slightly
+   reduced the contrast of the output image.
+   https://rt.cpan.org/Ticket/Display.html?id=111871
+
+ - the new autolevels filter now uses a lookup table for 8-bit images
+   to avoid a floating point multiply for each sample.
+   https://rt.cpan.org/Ticket/Display.html?id=111871
+
+ - fixed several memory leaks detected by valgrind:
+
+   - addcolors() leaked the temporary array of colors supplied to the
+     internal API
+
+   - make_palette() leaked the temporary image array (not the images
+     themselves) passed to the internal API.
+
+   - combine()/i_combine() leaked its working row buffers
+
+   - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
+     buffer if there were too many colors
+
+   - getcolorcount()/i_count_colors() leaked the sample buffer if
+     there were too many colors.
+
+   - the nearest_color filter (undocumented until I find a use for it)
+     leaked both temporaries passed to the API and internal buffers
+
+ - fixed some uninitialized memory usage detected by valgrind:
+
+   - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
+     i_matrix_transform_bg() didn't initialize a working color value
+     if there was zero pixel coverage.
+
+   - i_ft2_cp() didn't initialize the complete color when producing an
+     intermediate image.  This caused uninitialized value usage when
+     logging the color.
