I think we need to wait for nsopenssl 3.0, updated installation documentation, and perhaps some more non-core module cleanup and testing before making 4.0 the recommended distribution. I don't know of any modules other than nsopenssl that need serious work. Some of the db drivers still need to be updated to match the extracted nsdb. Non-core modules probably need work to be vserver-aware.

I don't think it is on aolserver.com yet. Mat has also updated the OpenACS distribution with newer modules - https://openacs.org/forums/message-view?message_id=84628
All that aside, the more bugs we can stamp out of the beta the better, so please test away and report bugs on SourceForge! The ACT is currently slogging through dozens of previously ignored ticket items, but new bugs are obviously getting priority.
