+[heading Asio 1.6.1 / Boost 1.48]
+
+* Implemented various performance improvements, including:
+ * Using thread-local operation queues in single-threaded use cases (i.e. when
+ `concurrency_hint` is 1) to eliminate a lock/unlock pair.
+ * Allowing some `epoll_reactor` speculative operations to be performed
+ without holding the lock.
+ * Improving locality of reference by performing an `epoll_reactor`'s I/O
+ operation immediately before the corresponding handler is called. This also
+ improves scalability across CPUs when multiple threads are running the
+ `io_service`.
+ * Specialising asynchronous read and write operations for buffer sequences
+ that are arrays (`boost::array` or `std::array`) of exactly two buffers.
+* Fixed a compile error in the regex overload of `async_read_until`
+ ([@https://svn.boost.org/trac/boost/ticket/5688 #5688]).
+* Fixed a Windows-specific compile error by explicitly specifying the
+ `signal()` function from the global namespace
+ ([@https://svn.boost.org/trac/boost/ticket/5722 #5722]).
+* Changed the `deadline_timer` implementation so that it does not read the
+ clock unless the timer heap is non-empty.
+* Changed the SSL stream's buffers' sizes so that they are large enough to hold
+ a complete TLS record ([@https://svn.boost.org/trac/boost/ticket/5854 #5854]).
+* Fixed the behaviour of the synchronous `null_buffers` operations so that they
+ obey the user's non-blocking setting
+ ([@https://svn.boost.org/trac/boost/ticket/5756 #5756]).
+* Changed to set the size of the select `fd_set` at runtime when using Windows.
+* Disabled an MSVC warning due to const qualifier being applied to function type.
+* Fixed a crash due that occurs when using the Intel C++ compiler
+ ([@https://svn.boost.org/trac/boost/ticket/5763 #5763]).
+* Changed the initialisation of the OpenSSL library so that it supports all
+ available algorithms.
+* Fixed the SSL error mapping used when the session is gracefully shut down.
+* Added some latency test programs.
+* Clarified that a read operation ends when the buffer is full
+ ([@https://svn.boost.org/trac/boost/ticket/5999 #5999]).
+* Fixed an exception safety issue in `epoll_reactor` initialisation
+ ([@https://svn.boost.org/trac/boost/ticket/6006 #6006]).
+* Made the number of strand implementations configurable by defining
+ `BOOST_ASIO_STRAND_IMPLEMENTATIONS` to the desired number.
+* Added support for a new `BOOST_ASIO_ENABLE_SEQUENTIAL_STRAND_ALLOCATION` flag
+ which switches the allocation of strand implementations to use a round-robin
+ approach rather than hashing.
+* Fixed potential strand starvation issue that can occur when `strand.post()`
+ is used.

* Added support for signal handling, using a new class called `signal_set`.
