    * No changes from 0.78

0.77_01 Sun, February 22, 2009
    * Everything
      - This package now requires its XS components. Not using
        Sub::Name lead to different behavior and bugginess in the pure
        Perl version of the code. A Moose test would fail when run
        against the pure Perl version of this code.

    * Moose::Meta::Instance
      - The inline_* methods now quote attribute names themselves, and
        don't expect to receive a quoted value.
