+Imager-File-PNG 0.94
+====================
+
+ - Makefile.PL / metadata improvements
+
+Imager-File-PNG 0.93
+====================
+
+ - add support for setting the level of zlib compression used with the
+ png_compression_level tag.
+
+Imager-File-PNG 0.92
+====================
+
+ - update the bundled/modified Devel::CheckLib to handle the gcc-4
+ symlink on Cygwin
+
+Imager-File-PNG 0.91
+====================
+
+ - skip the benign tests before libpng 1.6.0 since older versions do
+ not treat an extranrous palette as any sort of error.
+
+Imager-File-PNG 0.90
+====================
+
+ - support libpng 1.6.10.
+ 1.6.10 changed CRC errors from benign errors to normal errors,
+ which broke the test which used CRC errors to check for benign
+ error support. Switched to using a 1-bit grey-scale image with a
+ palette to test for benign errors.

+
+Imager-File-PNG 0.89
+====================
+
+ - treat a version mismatch between library and headers as a probe
+ failure.
+ https://rt.cpan.org/Ticket/Display.html?id=86659
+
+ - the check for benign error support is more complex than a simple
+ library version check, check for the appropriate macro.
+ Thanks for Slaven Rezic for following up on my CPAN Testers result
+ queries.
