0.58
    !! This release has an incompatible change regarding !!
    !! how roles add methods to a class !!

    * Roles and role application
      ! Roles now add methods by calling add_method, not
        alias_method. They make sure to always provide a method
        object, which will be cloned internally. This means that it is
        now possible to track the source of a method provided by a
        role, and even follow its history through intermediate roles.

        This means that methods added by a role now show up when
        looking at a class's method list/map. (Dave Rolsky)

    * Makefile.PL
      - From this release on, we'll try to maintain a list of
        conflicting modules, and warn you if you have one
        installed. For example, this release conflicts with ...
        - MooseX::Singleton        <= 0.11
        - MooseX::Params::Validate <= 0.05
        - Fey::ORM                 <= 0.10

        In general, we try to not break backwards compatibility for
        most Moose users, but MooseX modules and other code which
        extends Moose's metaclasses is often affected by very small
        changes in the Moose internals.

    * Moose::Meta::Method::Delegation
    * Moose::Meta::Attribute
      - Delegation methods now have their own method class. (Dave
        Rolsky)

    * Moose::Meta::TypeConstraint::Parameterizable
      - Added a new method 'parameterize' which is basically a factory
        for the containing constraint.  This makes it easier to create
        new types of parameterized constraints. (jnapiorkowski)

    * Moose::Meta::TypeConstraint::Union
      - Changed the way Union types canonicalize their names to follow
        the normalized TC naming rules, which means we strip all
        whitespace. (jnapiorkowski)

    * Moose::Util::TypeConstraints
      - Parameter and Union args are now sorted, this makes Int|Str
        the same constraint as Str|Int. (jnapiorkowski)
      - Changes to the way Union types are parsed to more correctly
        stringify their names. (jnapiorkowski)
      - When creating a parameterized type, we now use the new
        parameterize method. (jnapiorkowski)
      - Incoming type constraint strings are now normalized to remove
        all whitespace differences. (jnapiorkowski)
      - Changed the way we parse type constraint strings so that we now
        match TC[Int,Int,...] and TC[name=>Str] as parameterized type
        constraints.  This lays the foundation for more flexible type
        constraint implementations.

    * Tests and docs for all the above. (jnapiorkowski)

    * Moose::Exporter
    * Moose
      - Moose::Exporter will no longer remove a subroutine that the
        exporting package re-exports. Moose re-exports the
        Carp::confess function, among others. The reasoning is that we
        cannot know whether you have also explicitly imported those
        functions for your own use, so we err on the safe side and
        always keep them. (Dave Rolsky)
        - added tests for this (rafl)

    * Moose::Meta::Class
      - Changes to how we fix metaclass compatibility that are much
        too complicated to go into. The summary is that Moose is much
        less likely to complain about metaclass incompatibility
        now. In particular, if two metaclasses differ because
        Moose::Util::MetaRole was used on the two corresponding
        classes, then the difference in roles is reconciled for the
        subclass's metaclass. (Dave Rolsky)
      - Squashed an warning in _process_attribute (thepler)

    * Moose::Meta::Role
      - throw exceptions (sooner) for invalid attribute names (thepler)
        - added tests for this (thepler)

    * Moose::Util::MetaRole
      - If you explicitly set a constructor or destructor class for a
        metaclass object, and then applied roles to the metaclass,
        that explicitly set class would be lost and replaced with the
        default.

    * Moose::Meta::Class
    * Moose::Meta::Attribute
    * Moose::Meta::Method
    * Moose
    * Moose::Object
    * Moose::Error::Default
    * Moose::Error::Croak
    * Moose::Error::Confess
      - All instances of confess() changed to use overridable
        C<throw_error> method. This method ultimately calls a class
        constructor, and you can change the class being called. In
        addition, errors now pass more information than just a string.
        The default C<error_class> behaves like C<Carp::confess>, so
        the behavior is not visibly different for end users.
