- Chromium 64.0.3282.119 which should include partial MP3 support. - Fixed stability issues when you closed the browser due to circular interface references. - Fixed TCefRTTIExtension thanks to Pier. - Added the JSRTTIExtension demo to test TCefRTTIExtension. - Added the TCustomResponseFilter class to filter the resource contents. - Added the ResponseFilterBrowser demo to test the new TCustomResponseFilter class.
