The November CTP download is available for MSDN and TechNet subscribers. The public download is available here. A small stand-alone MSI for Report Builder 3.0, November CTP, is now available for download here. The feature pack download is also available and includes Report Builder 3.0 as well as the RS add-ins for SharePoint 2007 and SharePoint 2010.
The Data Platform Insider blog provides an overview of what's new in CTP release for SQL Server 2008 R2. If you are reading this blog, you are probably interested in knowing what’s specifically new compared to the previous August CTP in Reporting Services 2008 R2 November CTP:
We look forward to hearing your feedback on Reporting Services 2008 R2 November CTP in the dedicated MSDN discussion forum.
Do you know if there is any update for Report Builder 3.0? Also, a general question - can I use Report Builder 3.0 to connect to SQL 2008 Reports? The August CTP version suggests I can only connect to a SQL 2008 R2 Report Server? Please can you confirm?
yes there are updates in Report Builder 3.0 as well, specifically for the new data visualization report items, report part gallery, and shared datasets. Report Builder 3.0 produces RDLs with the 2010 format, which works with only with Reporting Services 2008 R2.
Note that with BIDS in November CTP you can choose to create reports that target RS 2008, or RS 2008 R2.
