You should preferably ask the author of geometry.sty not to put beta
versions to CTAN. The TeX Live team is not large enough to test all
updated packages for possible problems.

Although I am a skilled user, I never update during a work on o
project unless a critical security update is available. I sometimes
delay updates even several months, sometimes even a year just to be
sure that everything will continue to work the same way. And you can
use tlmgr to make backup.
