- updated to 0.17
- A bug in Class::Load caused test failures when Module::Runtime 0.012 was
used with Perl 5.8.x. Reported by Zefram. RT#74897. ( Jesse Luehrs )

- Require Module::Runtime 0.012, which has a number of useful bug fixes.

- Small test changes to accomodate latest version of
Module::Implementation. There's no need to upgrade if you're already using
0.14

- Use Module::Implementation to handle loading the XS or PP versions of the
code. Using this module fixes a few bugs.

- Under taint mode, setting an implementation in the CLASS_LOAD_IMPLEMENTATION
env var caused a taint error.

- An invalid value in the CLASS_LOAD_IMPLEMENTATION env var is now detected
and reported immediately. No attempt is made to load an invalid
implementation.

- Fix some bugs with our use of Try::Tiny. This could cause warnings on some
systems with Class::Load::XS wasn't installed. Fixes RT#72345.
