developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
* New feature: concept checks. The library now does better compile-time
error checking to make sure that the types used to instantiate
library templates conform to the templates' requirements.
* Removed two non-standard-conforming extensions: the second, defaulted
template parameter in bitset, and the third, default template
parameter in deque.
* Many bug fixes, performance enhancements, and compatibility improvements.
