Plone-app-layout

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

Bug fixes:

- Fix sitemap.xml.gz for plone.app.multilingual (>= 2.x) but breaks it for
LinguaPlone and plone.app.multilingual 1.x
If this is a problem then please see bedbfeb67 on 2.5.x branch for how to
maintain compatibility with these products.

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

Bug fixes:

- Document byline viewlet is now displayed only to anonymous users if permited by the `Allow anyone to view 'about' information` option in the `Security Settings` of `Site Setup` (closes `CMFPlone1556`_).
Code used to show the lock status and history view was removed from the document byline as this information was not available to anonymous users anyway.

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

Incompatibilities:

- Deprecated ``plone.app.layout.globals.pattern_settings``.
Moved view to ``Products.CMFPlone.patterns.view``.
Deprecated also pointless interface for this view.

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

New:

- Construct the site logo URL to be rooted at ISite instances returned by
``zope.component.hooks.getSite`` and not only rooted at portal root.
This makes it possible to have sub sites with local registries which return
a different logo.

Fixes:

- Fixed html validation: element nav does not need a role attribute.
[maurits]

- Fixed invalid html of social viewlet by moving the schema.org tags
to the body in a new viewlet ``plone.abovecontenttitle.socialtags``
and adding ``itemScope`` and ``itemType`` there.
Fixes https://github.com/plone/Products.CMFPlone/issues/1087

- Fix test isolation problems: if a test calls transaction.commit() directly or
indirectly it can not be an integration test, either avoid the commit or
change the layer into a functional one.

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

New:

- Switched deprecated ``listingBar`` CSS class to ``pagination``.
[davilima6]

Fixes:

- Adapted to changed Zope 4 ``browser:view`` semantics. We either
need a ``template`` ZCML argument or a ``__call__`` method on the
class. [thet]
