- Default plugin loading policy can be specified using the new `--plugin-policy=[allow|block|detect]` command-line flag. - Move CefRequestHandler::OnBeforePluginLoad to CefRequestContextHandler and add a new policy argument that supports different actions (allow, block, detect, disable) on a per-plugin-instance basis. - Add CefContextMenuHandler::RunContextMenu for providing a custom context menu implementation. - Add CefResourceBundleHandler::GetDataResourceForScale for returning scaled resources (issue #1272). - Add CefResourceBundle for retrieving resources from the resource bundle (*.pak) files loaded by CEF during startup or via the CefResourceBundleHandler. - Linux: Fix Debug build IO access warning with CefGetMimeType. - cef_unittests: Move the refcounting implementation from TestHandler to subclasses in order to support interface inheritance from subclasses.
