Regular readers of my blog will remember my post about how to get PowerShell for SQL into your regular PowerShell window. Except that if you've just installed SQL Server 2008 RC0, you may have noticed it doesn't work any more.
Never fear, they've just changed the name a bit. They've put 100 on the end of both. So just change your console file to list the two snapins as SqlServerProviderSnapin100 and SqlServerCmdletSnapin100. Calling PowerShell with the -PSConsoleFile option still works as before of course.
On a lighter note, they've fixed the case sensitivity. I can now "cd databases" just fine, without it needing me to use a capital D.
