 Mitogen for Ansible
 ~~~~~~~~~~~~~~~~~~~
 
+* `#324 <https://github.com/dw/mitogen/issues/324>`_: plays with a custom
+  module_utils would fail due to fallout from the Python 3 port and related
+  tests being disabled.
+
 * `#331 <https://github.com/dw/mitogen/issues/331>`_: fixed known issue: the
   connection multiplexer subprocess always exits before the main Ansible
   process exits, ensuring logs generated by it do not overwrite the user's
   prompt when ``-vvv`` is enabled.
 
+* `#332 <https://github.com/dw/mitogen/issues/332>`_: support a new
+  :data:`sys.excepthook`-based module exit mechanism added in Ansible 2.6.
+
+* `#338 <https://github.com/dw/mitogen/issues/338>`_: compatibility: due to
+  Ansible's implementation, changes to ``/etc/environment`` made by a task are
+  reflected in the runtime environment of subsequent tasks, but only if those
+  tasks set ``become: true``, or if SSH multiplexing is disabled. Changes to
+  ``/etc/environment`` are now monitored and always reflected.
+
+* Runs with many targets executed the module dependency scanner redundantly,
+  due to missing synchronization, creating significant extra work in the
+  connection multiplexer process. For one real-world playbook, the scanner
+  runtime was reduced by 95%, which may be apparent
+
+
+Core Library
+~~~~~~~~~~~~
+
+* `#339 <https://github.com/dw/mitogen/issues/339>`_: the LXD connection method
+  was erroneously executing LXC Classic commands.
