From 0.8 to 0.9

This is a significant update compared to 0.8. Lots of changes have been made to ensure a stable and consistent API. High level changes are AMD support, batch rendering, and API reshaping.

• All properties passed to the View constructor are now copied to the View, this may be harmful if you were directly passing a model: new View(myModel) instead of: new View({ model: myModel })
• view.render() now returns the View, change to render().promise() to get a promise.
• Rename fetch and render overrides to fetchTemplate and renderTemplate respectively.
• Remove RequireJS shim.
• Event bubbling has been removed. Pass the parent into the child.
• Overriding insert or html on a parent view now affects how it inserts or sets child views. In 0.8, this override would be defined on the child itself. If you are overriding insert or html on a child view, move it to the parent view. For clarity:
• If insert is overridden, it will be called when subViews are inserted within that View (via insertView)
• If html is overridden, it will be called:
  • When applying a template.
  • When setting subViews (via setView)

We will continue to upgrade and make changes along side the edge version of Backbone. There is a very large structural change that is coming soon (removal of View#options). We are working on refactoring LayoutManager to work with this change.
