threshold option doesn't work

[mdaljac]

Describe the bug
On mobile, we need to swipe really long distance to actually slide to the next item. I have tried option "threshold" with touchDrag: { threshold: 0.1 },, but everything is the same.

After checking release list, found that this option is only available from 0.15.0.
It works in my project after updated from 0.13.1 to 0.15.0, for your information.
