I missed the push feature in the update notes, but that sounds like a very handy feature. I might just install 4.5 now….
ONLY if you have no important plugins, like Reality, GenX etc installed. 4.5RC1 is not compatible with those (I’ve seen a reassurance that updates come for 4.5 when it is stable and not a release candidate). I did not have anything important, so I installed. Just so that you know, and are warned of this fact.
