Installed version 12.3 on my server and clients last week without much of an issue. So far seems to work well and the number of random Amazing Charts crashes that would occur is MUCH improved. Agree with others that the prescription module is a bit snappier as well.
But really it's not having to restart Amazing Charts after a crash - sometimes several times a work day - that has made a significant quality of life difference for my office.
