Membership Pro compatible with WP 4.3.1

I would like to upgrade to 4.3.1 in Wordpress, but would like to make sure that Membership Pro is still compatible?

I tried upgrading to Membership 2 but the process didn't go too well. 6 users out of 300 retained their subscription details. Found guest/visitor pages weren't working as intended. 3 hours of trying to get it working and i couldn't afford the downtime so i had to roll it back to Membership Pro.

Anyway, i will try upgrading again down the track, but in the interim would like to know if upgrading Wordpress won't break what we have working at the moment.

Thank you.
