[section:changes Changes since boost 1.35]
The 1.36.0 release of Boost includes a few new features in the thread library:
* New generic __lock_multiple_ref__ and __try_lock_multiple_ref__ functions for locking multiple mutexes at once.
* Rvalue reference support for move semantics where the compilers supports it.
* A few bugs fixed and missing functions added (including the serious win32 condition variable bug).
* `scoped_try_lock` types are now backwards-compatible with Boost 1.34.0 and previous releases.
* Support for passing function arguments to the thread function by supplying additional arguments to the __thread__ constructor.
* Backwards-compatibility overloads added for `timed_lock` and `timed_wait` functions to allow use of `xtime` for timeouts.
[heading Changes since boost 1.34]
Almost every line of code in __boost_thread__ has been changed since the 1.34 release of boost. However, most of the interface
changes have been extensions, so the new code is largely backwards-compatible with the old code. The new features and breaking

* __mutex__ is now never recursive. For Boost releases prior to 1.35 __mutex__ was recursive on Windows and not on POSIX platforms.
* When using a __recursive_mutex__ with a call to [cond_any_wait_link `boost::condition_variable_any::wait()`], the mutex is only
unlocked one level, and not completely. This prior behaviour was not guaranteed and did not feature in the tests.
