IIRC tagged delay pools were merged, definitely per-user delay pools
(class 4 pools) support was merged, ESI, modular disk IO stuff taken
further.

Some of that is really nasty to try to get working in 2.x (in particular
the tagged delay pools), and is largely benefits from 'internal
restructuring'.

The STL stuff was a compromise made when the c++ 'compiles now'
transition was done, but IMO we should be supporting the STL now,
particularly as boost which you reference in this thread is layered on
the STL. (It's not 'STL done right' it's 'Beta quality STL' - the goal
of the boost authors is to be the on-ramp for future releases of the
STL, as has happened recently with some of the core boost types).
