Where are you seeing that beta 1 is available? We have not made an
official release of OpenACS 4.x at this point. The SDM may list an
anticipated release date, but that was done a while ago for testing of
the SDM.
The schedule you see at /4/schedule is pretty much right on. Many
things are working, and the porting effort has become much more of a
parallel process than the sequential one described in the schedule.
So, trust the schedule and especially the status report. OpenACS is
*not* in beta just yet.
