Still on 2.2.0.11....safe to upgrade yet?

After hearing about all the problems with 2.3.45, I decided to wait to upgrade. I’m still getting notifications from CPF that there are updates available for download. Is it safe to download and install the new version? Am I still going to have to backup registry settings and manually fix Windows Security Center, or have those issues been resolved?

It’s safe to come out of your hide out, now.
