Wow, just realised 3 of Heikki's performance patches aren't mentioned
either:
- CheckpointStartLock removal
- I/O reduction during recovery
- Tuning of Visibility code
I'm not sure what the rationale is for not mentioning these things.
They're at least as important, if not more so, than mentioning minor
source code changes.
If people understand there aren't 13 performance improvements there are
at *least* 19+ that is a positive message to help people decide to
upgrade.
