Instances of boost::thread and of the various lock types are now movable.
</li>
<li>
Threads can be interrupted at interruption points.
</li>
<li>
Condition variables can now be used with any type that implements the
Lockable concept, through the use of <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">condition_variable_any</span></code>
(<code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">condition</span></code> is a typedef to <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">condition_variable_any</span></code>, provided for
backwards compatibility). <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">condition_variable</span></code>

Thread IDs are separated from boost::thread, so a thread can obtain it's

and IDs can be used as keys in associative containers, as they have the
full set of comparison operators.
</li>
<li>
Timeouts are now implemented using the Boost DateTime library, through
a typedef <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">system_time</span></code> for absolute timeouts,
and with support for relative timeouts in many cases. <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">xtime</span></code>
is supported for backwards compatibility only.

<li>
Locks are implemented as publicly accessible templates <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">lock_guard</span></code>, <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">unique_lock</span></code>,
<code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">shared_lock</span></code>, and <code><span class="identifier">boost</span><span class="special">::</span><span class="identifier">upgrade_lock</span></code>,

been extended to include publicly available <code><span class="identifier">lock</span><span class="special">()</span></code> and <code><span class="identifier">unlock</span><span class="special">()</span></code> member functions, which are used by
the lock types.

* Threads can be interrupted at interruption points.
* Condition variables can now be used with any type that implements the
Lockable concept, through the use of `boost::condition_variable_any`
(`boost::condition` is a typedef to `boost::condition_variable_any`, provided for

* Timeouts are now implemented using the Boost DateTime library, through a
typedef `boost::system_time` for absolute timeouts, and with support for relative
timeouts in many cases. `boost::xtime` is supported for backwards compatibility
only.
* Locks are implemented as publicly accessible templates `boost::lock_guard`,
`boost::unique_lock`, `boost::shared_lock`, and `boost::upgrade_lock`, which are

it is no longer necessary now that mutex types now have public `lock()` and
`unlock()` member functions.
* `scoped_lock` constructors with a second parameter of type bool are no
longer provided. With previous boost releases,
`boost::mutex::scoped_lock some_lock(some_mutex,false);`
could be used to create a lock object that was associated with a mutex,
