------------------

- Add Plone 5 warning.
[gforcada]

- Include TinyMCE languages from mockup.
[petschki]

- Raise minimum ``Products.CMFPlone`` requirement to 4.3.4 to ensure
compatibility with jQuery 1.9+. jQuery 1.11.1 is included in recent
``mockup``.
[thet]

- Always include CSS and JS SourceMap files. They are only loaded, when the
browser's developer console is open. Replaces previous behavior, where
uninified (and broken) resources were loaded when mockup was installed, which
was also an ugly implicit development mode behavior.
[thet]

- Use a mimetype selector for richtext areas, if multiple mimetypes are allowed.
[thet]

- Allow to remove a selected option in the ``select2`` widget if the field
is not required
[frapell]

- Test fixes.
[thet]

- add jsi18n integration
[vangheem, kiorky]

------------------

- Remove configuration of plone.app.event's ``start`` and ``end`` fields in the
``dx_bbb`` module. Requires ``plone.app.event >= 1.2``, which does the widget
configuration by itself. There is no point in using a previous version of
plone.app.event together with plone.app.widgets.
[thet]

- Store RelatedItems in correct order.
