• The snippet type parameter of SnippetChooserPanel can now be omitted, or passed as a model name string rather than a model class (Joss Ingram)

• Fix: Resizing single pixel images with the "fill" filter no longer raises "ZeroDivisionError" or "tile cannot extend outside image"
• Fix: The queryset returned from search operations when using the database search backend now correctly preserves additional properties of the original query, such as prefetch_related / select_related

• Fix: Page copy now works with pages that use multiple inheritance (Jordi Joan)
• Fix: Form builder pages now pick up template variables defined in the get_context method (Christoph Lipp)
• Fix: When copying a page, IDs of child objects within page revision records were not remapped to the new objects; this would cause those objects to be lost from the original page when editing the new one
• Fix: Newly added redirects now take effect on all sites, rather than just the site that the Wagtail admin backend was accessed through
• Fix: Add user form no longer throws a hard error on validation failure
