Does boost have a spec (document) where it mentions which new language features in C++11 are permitted to be used in new libraries? -Sid Sacek

No, because the answer is that any C++11 feature can be used in new libraries, and in old libraries too. The critical issue is support for compilers that don't supply a particular shinny new feature. Today most Boost developers are trying to support all compilers that (except for export) are C++03 compliant. A howl would likely go up from reviewers if someone submitted a library that didn't work on C++03 compilers. Even that isn't absolute. If a library's sole purpose was to support or ease the use of some C++11 feature, then it might well not work on compilers that don't supply that feature. Boost has a bunch of feature macros in the config library to identify which compilers have various C++11 features. HTH, --Beman
