Imager release history. Older releases can be found in Changes.old
+ - add png_compression_level tag for writing PNG files.
+
+ - avoid flooring a second time in matrix transform interpolation.
+ https://rt.cpan.org/Ticket/Display.html?id=124001
+
+ - produce v2 metadata.
+ Includes change from the ticket and updates to sub-modules.
+ https://rt.cpan.org/Ticket/Display.html?id=127216
+
+ - improve error reporting for the polygon() method
+
+Imager 1.006 - 26 Aug 2017
+============
+
+ - the internal i_errors() function now correctly allocates the stack
+ space needed for its result.
+ https://rt.perl.org/rt3/Ticket/Display.html?id=131938
+
+ - t/100-base/020-color.t now uses Imager::Test's test functions
+ instead of its own.
+ https://rt.cpan.org/Ticket/Display.html?id=111993
+
+ - write_multi() now returns an error result (a false value) if called
+ with a non-(Imager image object). Previously it would typically
+ crash.
+ https://rt.cpan.org/Ticket/Display.html?id=117878
+
+ - improve the documentation of the jpegquality parameter when
+ writing JPEG files.
+
+ - add code to mitigate CVE-2016-1238, Imager will no longer search the
+ default current directory entry in @INC when searching for file
+ format support modules.
+
+Imager 1.005 - 16 Apr 2016
+============
+
+It's now been ten years since I switched to the new Changes file in
+release 0.55.
+
+ - revert the ivdformat probes, they don't work as is and trying to
+ fix them is too much work for now.
+
+Imager 1.004_004 - 15 Apr 2016
+================
+
+ - test that the ivdformat from Config is correct and look for a valid
+ one if it isn't.
+ For the strange Win32 failures.
+
+ - fix a copy and paste error in pod in samples/samp-form.cgi
+
+Imager 1.004_003 - 23 Mar 2016
+================
+
+ - add some extra error reporting to the I/O layers tests, this might
+ help catch a failure seen on Win32.
+ http://cpantesters.org/cpan/report/99781689-6bf5-1014-897a-75cb4eee1325
+
+Imager 1.004_002 - 20 Mar 2016
+================
+
+ - don't use the seek() method on opened() handles in
+ t/200-file/400-basic.t. In older versions of perl such handles are
+ only IO::Handle objects, not IO::File, and don't have a seek()
+ method.
+
+Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
+================
+
- 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 bugs in old
+ versions of giflib. I can't do much about the new bugs.
- - the new autolevels filter (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.

to avoid a floating point multiply for each sample.

- - the addcolors() method leaked memory.
+ - 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
+
+ - the internal process of upgrading a paletted image to a direct
+ color image would leak a context object reference count.
+
+ - a write failure when writing to a GIF file could leak memory.
+
+ - failing to write to a 1-bit/pixel ICO image could leak memory.
+
+ - Imager no longer deliberately leaks the context object from the
+ initial thread. This was done to ensure there was always a context
+ object available, but the code that needed that now handles the
+ lack correctly,
+
+ - 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.
Imager 1.004 - 8 Nov 2015
============
- a future version of Imager may allow an image to be read without
translation, for example a TIFF file that contains measurements
from an instrument. Currently Imager transforms the samples into
- the range 0.0 ... 1.0 which may means the user has to translates
+ the range 0.0 ... 1.0 which may means the user has to translate
the value back.
An untranslated image would be unusable as image data, so
- avoid static variables when capturing IPTC data from JPEG files
- - match Imager::Font;:T1's error message translations to those from
+ - match Imager::Font::T1's error message translations to those from
later versions of T1Lib.
- for libtiff versions that support extended warning handlers (3.8.0
