If you still are relying upon a PS/2 mouse, it really is time to think about upgrading to a USB mouse, but keep reading as there are some changes with Linux 4.5.

The PS/2 mouse change is that its module has been reworked in order to "limit number of protocols we try on pass-through ports to speed up their detection time." Not too exciting but it's an improvement nevertheless if stuck using this technology dating back to the late 80's.

The other more noteworthy work includes new drivers for eGalaxTouch and TS-4800 touch-screens, an updated Goodix touchscreen driver, Wacom W8001 touchscreen driver updates, and various other input driver updates.

More details from the Git pull request by Dmitry Torokhov.
