Moose::Role

• has now sets definition_context for attributes defined in
  roles. (doy)
  

Moose::Meta::Attribute

• When adding an attribute to a metaclass, if the attribute has
  no associated methods, it will give a deprecation
  warning. (hdp)
  
• Methods generated by delegation were not being added to
  associated_methods. (hdp)
  
• Attribute accessors (reader, writer, accessor, predicate,
  clearer) now warn if they overwrite an existing method. (doy)
  
• Attribute constructors now warn very noisily about unknown (or
  misspelled) arguments
  

Moose::Util::TypeConstraints

• Deprecated the totally useless Role type name, which just
  checked if $object->can('does'). Note that this is not the
  same as a type created by calling role_type('RoleName').
  

Moose::Util::TypeConstraints

Moose::Meta::TypeConstraint::DuckType

• Reify duck type from a regular subtype into an actual class
  (Sartak)
  
• Document this because Sartak did all my work for me
  (perigrin)
  

Moose::Meta::Attribute

• Allow Moose::Meta::TypeConstraint::DuckType in handles, since
  it is just a list of methods (Sartak)
  

Moose::Meta::Role

• The get_*_method_modifiers methods would die if the role had
  no modifiers of the given type (Robert Buels).
