| <li class="listitem"> |
| Added support for signal handling, using a new class called <code class="computeroutput"><span class="identifier">signal_set</span></code>. Programs may add one or more |
| signals to the set, and then perform an <code class="computeroutput"><span class="identifier">async_wait</span><span class="special">()</span></code> operation. The specified handler will |
| be called when one of the signals occurs. The same signal number may be |
| registered with multiple <code class="computeroutput"><span class="identifier">signal_set</span></code> |
| objects, however the signal number must be used only with Asio. Addresses |
| <a href="https://svn.boost.org/trac/boost/ticket/2879" target="_top">#2879</a>. |
| </li> |
| <li class="listitem"> |
| Added handler tracking, a new debugging aid. When enabled by defining |
| <code class="computeroutput"><span class="identifier">BOOST_ASIO_ENABLE_HANDLER_TRACKING</span></code>, |
| Asio writes debugging output to the standard error stream. The output records |
| asynchronous operations and the relationships between their handlers. It |
| may be post-processed using the included <code class="literal">handlerviz.pl</code> |
| tool to create a visual representation of the handlers (requires GraphViz). |
| </li> |
| <li class="listitem"> |
| Added support for timeouts on socket iostreams, such as <code class="computeroutput"><span class="identifier">ip</span><span class="special">::</span><span class="identifier">tcp</span><span class="special">::</span><span class="identifier">iostream</span></code>. |

Any socket operations |
| which occur past the deadline will put the iostream into a bad state. |
| </li> |
| <li class="listitem"> |
| Added a new <code class="computeroutput"><span class="identifier">error</span><span class="special">()</span></code> |
| member function to socket iostreams, for retrieving the error code from |

| <li class="listitem"> |
| Added a new <code class="computeroutput"><span class="identifier">basic_deadline_timer</span><span class="special">::</span><span class="identifier">cancel_one</span><span class="special">()</span></code> function. This function lets you cancel |

| </li> |
| <li class="listitem"> |
| Added a new <code class="computeroutput"><span class="identifier">transfer_exactly</span><span class="special">()</span></code> completion condition. This can be used |

| </li> |
| <li class="listitem"> |
| Added a new <code class="computeroutput"><span class="identifier">buffer_copy</span><span class="special">()</span></code> function that can be used to copy the |
| raw bytes between individual buffers and buffer sequences. |
| </li> |
| <li class="listitem"> |

| </li> |
| <li class="listitem"> |
| Added friendlier compiler errors for when a completion handler does not |
| meet the necessary type requirements. When C++0x is available (currently |
| supported for <code class="literal">g++</code> 4.5 or later, and MSVC 10), <code class="computeroutput"><span class="identifier">static_assert</span></code> is also used to generate |

| <code class="computeroutput"><span class="identifier">BOOST_ASIO_DISABLE_HANDLER_TYPE_REQUIREMENTS</span></code>. |
| </li> |
| <li class="listitem"> |
| Added a new, completely rewritten SSL implementation. The new implementation |
| compiles faster, shows substantially improved performance, and supports |
| custom memory allocation and handler invocation. It includes new API features |
| such as certificate verification callbacks and has improved error reporting. |
| The new implementation is source-compatible with the old for most uses. |
