Improved monitoring and performance tuning (Tom, Bruce, Greg, Larry)
Overhead of statistics collection has been considerably reduced and new
statistics and system information is available. Better query logging
improves diagnostics and especially performance tuning. Server now
includes DTrace support. Indexes can now also be created CONCURRENTLY,
allowing application tuning without effecting server availability.
You forgot to Robert Lor - author of DTrace support.
