- Pass information to the renderer process synchronously on render thread creation and new browser creation to avoid race conditions (issue #744).

- Add the ability to pass extra information to child processes using a new CefBrowserProcessHandler::OnRenderProcessThreadCreated callback (issue #744).
- Fix OnBeforeChildProcessLaunch documentation (issue #754).
