I assumed there were only bug fixes/(no new types) in .NET 2.0 SP1 until I came across few posts which were mentioning DateTimeOffset structure, that was added in .NET 2.0 SP1.
Is there a full listing of the newly added types in .NET 2.0 SP1?

There were new interfaces added, like INotifyPropertyChanging, so there were new types added. The question is valid.
DateTimeOffset was added to 2.0 SP1 - I'm not aware of any other new types.
Given the coincidental timing, it's perhaps worth reminding people that 2.0 SP1 shipped with 3.5 RTM (i.e November 2007) and 2.0 SP2 shipped with 3.5 SP1.
