pro users dont receive them if zab doesnt want them to yet.

i think he will send pro users the update message when they get a pretty good final version out of the 4.9 series. then move on to 5.0 betas! oh what fun!

regarding in-network updates: the update system has all been stream-lined for the basic versions (4.9.xx, i cant remember exactly what version it was enabled in.). so when a user connects to the network, he will automatically download the installer. then limewire will tell him he should update with a popup. the installation is very smooth and requires only a few seconds and is the whole process is entirely without user-intervention. (besides pressing update now on the popup.) so if everyone atleast updates to 4.9.30, they will be auto-updated (or agressively nagged to update) on every release.
