Last week Microsoft released firmware updates for the Surface without any released notes. I did notice a new power slider option for the power icon in the taskbar that can be used to control the power balance (see my post) but other than that we had no idea what has changes.
Now we have the release notes for the July updates which includes graphics performance improvements and pen improvements:
