* Moved to github.
[maurits]

* Added views for plone.app.collection: standard and summary for now.
[jensens]

* Added try-except block around getting helper
when reindexing. This is not strictly our issue
but I still consider it a stability improvement.
[tmog]

* Remove deprecation warning on Zope 2.13:
Products.ATReferenceBrowserWidget moved to archetypes.referencebrowserwidget
DTMLFile is deprecated. import from App.special_dtml instead
[toutpt]

been issues with solr integration
