Flash white balance not set automatically. This is still true. The camera does not set flash white balance when you use the flash. No wonder so many people report funny color when using the flash. I don't really know if the reported problem with the fisheye lens is a bug, or just a problem with a few cameras, or what.
Some people do have it.
Others do not. I do not know enough about it to comment. Manual focus settings. Infinity settings at different focal lengths. A preliminary test show the manual focus feature is unchanged, and is only accurate for one focal length.
