Saw this on 43Rumours then verified on mu43.com. Among other things, it's supposed to quiet down the "whirring" sound. I did the update, but have not noticed any difference. Did it just before heading out the door to work, so have not had time to really look at it.
Also, when you do the update, it does 1.4 first. Then you go from 1.4 to 1.5.
