Ionic slide version 3.1.2 needs update to 3.3.1


Hi people,

after some time of researching how to check if I am moving forward or backward in an ion-slide,
I noticed that there are onSlideNextStart and onSlidePrevStart on swiper v 3.3.1 but not on the v3.1.2 .

It would be great if you can update the swiper to v3.3.1 because the documentation at swiper is for v3.3.1.
