3 - Fixed what looked like a bug in -ignore handling, although I couldn't seem
4 to write a test that triggered it.
6 - Removed hard dep on Test::Warn for the benefit of Moose.
11 - A single feature will now warn more than once if each warning consists of a
12 different error message.
17 - Added an -ignore parameter when importing Package::DeprecationManager. This
18 lets you explicitly ignore packages in the call stack when determining where
19 a deprecated feature was called.
24 - Made it possible to deprecate any feature, not just a subroutine or method.
