+[heading Asio 1.10.6]
+
+* Ensured errors generated by Windows' `ConnectEx` function are mapped to their
+  portable equivalents.
+
+* Added new macro `(BOOST_)ASIO_DISABLE_CONNECTEX` to allow use of `ConnectEx`
+  to be explicitly disabled.
+
+* Fixed a race condition in `windows::object_handle` when there are pending
+  wait operations on destruction.
+
+* Fixed IPv6 address parsing on FreeBSD, where a trailing scope ID would cause
+  conversion to fail with `EINVAL`.
+
+* Worked around shared library visibility issues by ensuring Asio types use
+  default visibility.
+
+* Changed the SSL wrapper to call the password callback when loading an
+  in-memory key.
+
+* Fixed false SSL error reports by ensuring that the SSL error queue is cleared
+  prior to each operation.
+
+* Fixed an `ssl::stream<>` bug that may result in spurious 'short read' errors.
+
+* Removed a redundant null pointer check in the SSL engine.
+
+* Added options for disabling TLS v1.1 and v1.2.
+
+* Removed use of deprecated OpenSSL function `ERR_remove_state`.
+
+* Fixed detection of various C++11 features with Clang.
+
+* Fixed detection of C++11 `std::addressof` with [^g++].
+
+* Changed multicast test to treat certain `join_group` failures as non-fatal.
+
+* Decoupled Asio unit tests from Boost.Test.
+
+* Changed the tutorial to use `std::endl` to ensure output is flushed.
+
+* Fixed an unsigned integer overflow reported by Clang's integer sanitizer.
+
+* Added support for move-only return types when using a `yield_context` object
+  with asynchronous operations.
+
+* Changed `yield_context` to allow reentrant calls to the completion handler
+  from an initiating function.
+
+* Updated detection of Windows Runtime to work with latest Windows SDK.
