Release managers, can I merge these Boost.Parameter changes from trunk to
release?

If yes, probably the sooner I do it the better it is so I can monitor the
tests. I did a local merge and I'm using locally merged release in my
projects/tests -- everything is fine, and the x::tag::_ bug is fixed, as far
as I can tell.

Please advice.

Thanks a lot.
