Please see the Beta 2 Announcement for details of what's new, changed, enhanced, fixed or even removed from the bits.
In the blog entry SharpDevelop Presentation we announced our plans to reverse-integrate SharpReport in the future. This has happened as of today's Beta 2 launch of SharpDevelop.
The SharpReport Repository
SharpReport has a repository of its own now: svn://sharpdevelop.net/sharpreport/trunk
The checkout procedures are explained in this Wiki entry.
Building SharpReport
After checkout, run debugbuild.bat:

This will populate the bin folder with the SharpReport standalone designer plus the SharpReport addin:

Simply execute SharpDevelop.SharpReport.exe and you will be presented with the familiar SharpDevelop IDE, however, slimmed down to support SharpReport-needed functionality only:

(Please note that as of this writing, the SharpReport samples haven't yet been checked in to the new repository)
Where Do I Get Support?
SharpReport now has a dedicated support forum, and Peter will be blogging about SharpReport features here.
Where Can I Download Binaries?
At this point, there are no precompiled packages available other than SharpReport shipping in Beta 2 of SharpDevelop 2.1. Note, however, that Beta 2 is shipping an older version of SharpReport than is available via the repository because of reverse integration.
