Microsoft BizTalk Server 2006 Beta2 is now available on Microsoft Beta Place. If you have not signed up already for BizTalk 2006 Beta program you can follow the instructions that I posted in this previous post in order to download the bits. If you have already signed up for BizTalk Beta 1 then you can just go to https://beta.microsoft.com, sign in with your account and download the latest BT 2006 beta.
The setup/configuration is pretty much the same so you can follow the steps from my previous post but now you have to use the RTM version of Visual Studio 2005 and Windows SharePoint Services 2003 with SP2.
BizTalk 2006 Beta 2 is a production-ready build, and of course upgrade from Beta 2 to RTM will be supported.
So, what's new feature wise in Windows SharePoint Services adapter included in BizTalk 2006 Beta 2 when compared to previous Beta 1? See below:
