After upgrade to kernel 4.1.1-r1 from 4.0 clickpad 3-fingers tap, which is mapped to the middle mouse button, does not work anymore. It registers 2 fingers tap (right mouse button) instead.
I'm not 100% sure that it is related to kernel version though, as there were other packages upgraded as well right before kernel update.

List of upgraded packages:

synaptics config (worked prior to upgrade):
Code:

Section "InputClass"
        Identifier "SynPS/2 Synaptics TouchPad"

Downgraded to 4.0.4 - 3 fingers click works again. Didn't test other kernels.
So the problem is definitelly in the kernel, not in drivers. 4.0.4 registers 3-fingers click on clickpad, 4.1.1-r1 does not.


upd: known bug https://bugzilla.kernel.org/show_bug.cgi?id=100481
