Those links are years and years out of date. You should be looking at
the daily regression tests.

See http://beta.boost.org/development/testing.html

In particular,

All of TR1 except special math functions went into C++11. Some other
new C++11 library features, like enable_if, were based at least
vaguely on boost libraries.

Use of boost libraries has become an accepted practice, and it is now
widely known that many libraries from boost are on a track to become
part of the C++ standard or its TRs. So there is less interest in
keeping a scorecard.

That isn't correct. Filesystem is on track for C++next, but we won't
know for another couple of months whether that means TR2 or a version
of the standard itself.

The Boost Chrono docs are correct. The design of std chrono was
influenced by Boost Date-Time, and a number of boost people were
involved in chrono's development, but it wasn't a boost library.
