If you go to renshuu's page in the Play Store, there should be an option slightly down the page to join the beta program. If you join that, it should automatically download the new version for you.
So what's new? This version has shown marked speed improvements during loading for some users, and also has more protection built in for a rare white-screen bug that exists.
It would really mean a lot if you give it a try and let me know how it goes!
