version 0.7.15 final (26-May-2013):
	* djblets.extensions:
		* Extension classes can now define a 'metadata' variable to override
		  the package's metadata. This uses standard PyPI metadata fields.
		  Using this, single Python package can provide several extensions.

		* TemplateHooks subclasses can now override a new render_to_string
		  function to do their own processing and rendering, instead of
		  simply rendering the provided template_name.

		* The template_name parameter to TemplateHook is now optional.

		* The Django template loader cache is now reset when syncing
		  extension settings or enabling/disabling an extension.

	* djblets.webapi:
		* Added a "is_webapi_handler" attribute to WebAPIResource.

		  This allows for introspection from any middleware that's going
		  to call a view. It can test if this is set on the view to know
		  whether it's calling into an API handler.
