2.00 2014-04-11

    - New layout() method for customizing output of fields.
      Any custom elements which override string() will likely need modified.

    - Deprecated: reverse_single() and reverse_multi() are deprecated,
      and warn when used.
      If the new layout() is used, and there is no simple way to replicate
      the behaviour, these methods will have no affect.

    - TT template files changed - update them if you use a local copy.
      Files updated: field
      New files: field_layout, field_layout_block,
        field_layout_checkboxgroup_field, field_layout_comment,
        field_layout_contentbutton_field, field_layout_errors,
        field_layout_field, field_layout_javascript, field_layout_label,
        field_layout_label_field, field_layout_label_text,
        field_layout_multi_field, field_layout_parser,
        field_layout_select_field, field_layout_textarea_field.
      Files deleted due to layout() changes: checkboxgroup_tag,
        content_button, errors, input, input_tag, label, label_element,
        multi, select_tag, textarea_tag
      Unused files deleted: checkboxgroup.

    - New Filter::ForceListValue addresses rt bug #90813

    - render_label() and render_field() no longer require TT.
      Include render_label() in tests.

    - Fix typo in I18N::ja (Yusuke Watase).

    - Bundle our own (renamed) copy of MooseX::Attribute::Chained to avoid
      warnings under perl 5.19.x
