Releases
======================

tmt-1.31
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The :ref:`/spec/plans/provision` step is now able to perform
**provisioning of multiple guests in parallel**. This can
considerably shorten the time needed for guest provisioning in
multihost plans. However, whether the parallel provisioning would
take place depends on what provision plugins were involved,
because not all plugins are compatible with this feature yet. As
of now, only :ref:`/spec/plans/provision/artemis`,
:ref:`/spec/plans/provision/connect`,
:ref:`/spec/plans/provision/container`,
:ref:`/spec/plans/provision/local`, and
:ref:`/spec/plans/provision/virtual` are supported. All other
plugins would gracefully fall back to the pre-1.31 behavior,
provisioning in sequence.


tmt-1.30
