Hello, I've added boost.task-0.2.2 to boost.vault: - allow user-defined execution policies - private inheritance from noncopyable removed from task< R > and static_pool< R > copy-ctor and assignment-op private and unimplemented allowing correct move-semantics - worker_group removes all worker-threads in join_all() static_pool< R > does contain zero worker-threads after shutdown() or shutdown_now() - reintroduction of make_task() - internal refactoring/rework - documentation updated - tests updated - examples updated best regards, Oliver
