Yes.  We just merged this:

but you beat us to the announcement.

Not all.  We're still limited by some of the older C++11 compilers.
We'll have to see how things go on nightly builds.  As limitations
are found they can be documented in `Help/dev/source.rst`.

We will require std::unique_ptr at least.

I think so but haven't tried it.

We still support GCC 4.8.  IIRC its standard library doesn't have
the implementations in place.

No, at least not yet.  For now we're using libuv's thread primitives
instead.  Either way anything that needs to build during bootstrap
may not be able to use this.

Not sure.
