Deadlock trace file enhancements

Just browsing some deadlock trace files on 11gR2.

I normally look at sections:

• Deadlock Graph
• Information for the OTHER waiting session
• Information for THIS session

and very rarely go beyond section PROCESS_STATE.

But, casually browsing, I came across these sections relating to the killed session:

• Session Wait History
• Sampled Session History of session

Nice additions. When did that happen?
