 * [phrase library..[@/libs/array/ Array]:]
   * add support for Boost.Hash [@https://svn.boost.org/trac/boost/ticket/6791 #6791].
 
+* [phrase library..[@/libs/asio/ Asio]:]
+  * Changed the `epoll_reactor` backend to do lazy registration for `EPOLLOUT`
+    events.
+  * Fixed the `epoll_reactor` handling of out-of-band data, which was broken by
+    an incomplete fix in the last release.
+  * Changed Asio's SSL wrapper to respect OpenSSL's `OPENSSL_NO_ENGINE` feature
+    test `#define` ([@https://svn.boost.org/trac/boost/ticket/6432 #6432]).
+  * Fixed `windows::object_handle` so that it works with Windows compilers that
+    support C++11 move semantics (such as [^g++]).
+  * Improved the performance of strand rescheduling.
+  * Added support for [^g++] 4.7 when compiling in C++11 mode
+    ([@https://svn.boost.org/trac/boost/ticket/6620 #6620]).
+  * Fixed a problem where `signal_set` handlers were not being delivered when
+    the `io_service` was constructed with a `concurrency_hint` of 1
+    ([@https://svn.boost.org/trac/boost/ticket/6657 #6657]).
+
 * [phrase library..[@/libs/bimap/ Bimap]:]
   * Remove spurious dependency on Boost.Serialization, fixes [@https://svn.boost.org/trac/boost/ticket/3868 #3868].
   * Solve unused constructor parameter warning, fixes [@https://svn.boost.org/trac/boost/ticket/5749 #5749].
