Just out is WSS SP2. I have blogged about this before ... but now it is out.
Lots of people will be looking at it for the SQL Server 2005 support .... but ... I think one of the nicest features of this is around the reverse proxie features. There has always been an issue with WSS writing out fully qualified URLs. This causes a headache if your URL is different internally than in front of your reverse proxy. Most people want this configuration ... so we fixed it. You now have a much nicer way of controlling how links are rendered.
