20 - handle I/O close errors properly
25 - check image file limits set by set_file_limits()
27 - use TIFFReadDirectory() instead of TIFFSetDirectory() to step
28 through IFDs, since that handles IFD loops.
30 - update the bundled (and still modified) Devel::CheckLib
31 https://rt.cpan.org/Ticket/Display.html?id=69170
36 - the big types cleanup
41 - handle slightly different warning from libtiff 4.x

44 - replace (imager|tony)@imager.perl.org in the doc, since I don't
