* The ``MITOGEN_CPU_COUNT`` environment variable shards the connection
multiplexer into per-CPU workers. This improves throughput for large runs
especially involving file transfer, and is a prerequisite for future
in-process SSH support. One multiplexer starts by default, to match existing
behaviour.
* `Operon <https://networkgenomics.com/operon/>`_ no longer requires a custom
installation, both Operon and Ansible are supported by a unified release.
* `#419 <https://github.com/dw/mitogen/issues/419>`_,
`#470 <https://github.com/dw/mitogen/issues/470>`_, file descriptor usage
during large runs is halved, as it is no longer necessary to manage read and
write sides distinctly in order to work around a design limitation.

early in a run.

* `#419 <https://github.com/dw/mitogen/issues/419>`_: Connection setup is
pipelined, eliminating several network round-trips. Most infrastructure is in
place to support future removal of the final round-trip between a target
fully booting and receiving its first function call.
* `#595 <https://github.com/dw/mitogen/pull/595>`_: the :meth:`Router.buildah
<mitogen.parent.Router.buildah>` connection method is available to connect
to Buildah containers, and is exposed to Ansible as the ``buildah``
transport.
