I want to upgrade my sugar , but i don't know which version is the most reliable
7.7.1 is our most recent release and includes a variety of bug fixes from 7.7.0 and below, as well as some important security fixes. You can read more about this release at Version 126.96.36.199 Released!, but I would recommend upgrading to this, or at least 188.8.131.52 or 184.108.40.206 to get the security fixes.
As with any upgrade, make sure you are taking backups of your filesystem and database before the upgrade and doing any necessary testing.
I hope this helps!
