new firmware for a04 a03

Have I read this right, that it will allow the AO4 and others to write at 4x with certain media?

If so, I hope a region free version appears soon.
 
Old news, this claims that you will have an overheating problem if you burn 4X media in you AO3 or AO4. Like anyone is going to buy high priced 4X media to burn in a 2X burner.
