+Imager 0.94 - 15 Dec 2012
+=========================
+
+Variations on some of these changes were included in development
+releases.
+
+ - improved thread safety
+ - the internal error stack and log file handle are now in a per-thread
+ context object
+ - JPEG now captures IPTC information in a thread-safe way
+ - avoid globals where possible for warning capture in libtiff
+ - use a mutex to avoid re-entering thread-unsafe giflib
+ - use a mutex to avoid re-entering thread-unsafe tifflib
+ - use a mutex to avoid re-entering thread-unsafe T1Lib
+ - use a library handle per thread for freetype 2.
+ - use an engine handle per thread for freetype 1.x.
+ - originally these changes broke ABI compatibility, this has been
+ restored.
+
+ - clarify the return value of getpixel();
+ https://rt.cpan.org/Ticket/Display.html?id=81198
+
+ - fixed a race condition in parallel testing for T1
+
+ - fixed a bug in handling yoff for untransformed image-based fills
+
+ - documentation improvements for Imager::Fill
+
+ - FT2: report the library version while testing.
+
+Imager 0.93 - 15 Oct 2012
+===========
+
+Bug fixes:
+
+ - previously a transparency enabled GIF write (the default) would
+ always use a GIF89a header even if none of the images were
+ transparent.
+
+ - previously the probe step for freetype-config would fail on cygwin
+
+ - catch an invalid matrix parameter to convert() instead of crashing
+ https://rt.cpan.org/Ticket/Display.html?id=79922
+
+ - remove the 16-bit/sample limitation from the documentation for
+ setsamples(), it hasn't applied for many releases.
+ https://rt.cpan.org/Ticket/Display.html?id=79989
+
+ - don't copy setsamples() data parameter, it may be a large scalar
+ https://rt.cpan.org/Ticket/Display.html?id=79990
+
+ - clean up .dSYM directories generated performing probes on OS X
+ Mountain Lion.
+
+ - pass the --verbose command-line option through to Imager::Probe in
+ sub-module's Makefile.PLs
+ https://rt.cpan.org/Ticket/Display.html?id=75878
+
+Enhancements:
+
+ - support for giflib 5.0. (5.0.1 and later)
+ https://rt.cpan.org/Ticket/Display.html?id=79029
+ The giflib API Imager uses doesn't have a mechanism to set the
+ header version in 5.0.0.
+
+ - update the GIF library probe code to check for the new giflib 5.0.1
+ EGifSetGifVersion() function, and to check for the giflib 4.2.0
+ uninitialized gif89 bug.
+ https://rt.cpan.org/Ticket/Display.html?id=79679

- TODO:
- - flush output
- - documentation in C code
- - documentation of new tags, behaviour
- - FIXME for read_paletted: do we need to scale the palette colours
- based on the alpha?
+ - avoid static variables when capturing IPTC data from JPEG files
-Imager 0.90 - unreleased
+ - 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
+ or later), use them to avoid some global variables.
+
+ - note Image::ExifTool for better metadata support.
+ https://rt.cpan.org/Ticket/Display.html?id=79251
+
+Imager 0.92 - 14 Aug 2012
+===========
+
+ - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
+ correctly for both probing and runtime.
+ https://rt.cpan.org/Ticket/Display.html?id=77672
+
+ - allow building JPEG/imexif.c on C89 compilers.
+
+ - allow building GIF/imgif.c on C89 compilers.
+
+Imager 0.91 - 4 Jun 2012
+===========
+
+Bug fixes:
+
+ - The size of rotated images is no longer rounded up so aggressively.
+ Added rounding to the linear interpolation done for rotate() and
+ matrix_transform() for 1 and 3 channel 8-bit images.
+ Adjusted the two tranlate matrices used to build the final rotation
+ matrix to use the distance between the outlier pixels rather than
+ the pixel dimensions (ie. dimension-1).
+ With all of this the output of rotate(degrees => 270) on an 8-bit
+ image exactly matches the output of rotate(right => 270).
+ https://rt.cpan.org/Ticket/Display.html?id=77063
+
+Other changes:
+
+ - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
+ internals, those names only matter for the XS interface.
+
+ - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
+ the API level compiled into a loadable module such as
+ Imager::File::GIF doesn't match that of Imager. Previously it
+ could be difficult to determine exactly which module was failing to
+ load.
+ https://rt.cpan.org/Ticket/Display.html?id=77173
+
+ - added Imager->check_file_limits() as an interface to the
+ i_int_check_image_file_limits() API.
+
+ - Imager->set_file_limits(reset => 1) now resets the limits to the
+ defaults rather than setting them all to unlimited.
+
+ - wrote a brief security note as Imager::Security
+ https://rt.cpan.org/Ticket/Display.html?id=68910
+
+Imager 0.90 - 30 Apr 2012
===========
Bug fixes:
- the i_get_file_background() and i_get_file_backgroundf() APIs now
return int to indicate whether the i_background tag was found.
+ - PNG rework
+ - improve error reporting
+ - add png_interlace, png_bits tags
+ - read paletted images as paletted images, including transparency
+ - read 1 bit greyscale images as a type suitable for other file
+ handlers to write as bilevel
+ - read 16 bit/sample PNG as 16-bit/sample Imager images
+ - write "bilevel" paletted images as 1 bit grayscale images
+ - write paletted images as paletted images
+ - write 16-bit (or higher)/sample images as 16-bit/sample PNG
+ images
+ - improved metadata support
