=================
77.0 The Hangover
=================

The Avocado team is proud to present another release: Avocado 77.0,
AKA "The Hangover", is now available!

Release documentation: `Avocado 77.0
<http://avocado-framework.readthedocs.io/en/77.0/>`_

Users/Test Writers
==================

* The :meth:`avocado.Test.fetch_asset
  <avocado.core.test.Test.fetch_asset>` method now has two new
  parameters: ``find_only`` and ``cancel_on_missing``.  These can be
  combined to cancel tests if the asset is missing after a download
  attempt (``find_only=False``) or only if it's present in the local
  system without a download having been attempted during the test
  (``find_only=True``).  This can bring better determinism for tests
  that would download sizable assets, and/or allow test jobs to be
  executable in offline environments.

* The ``avocado-software-manager`` script, a frontend to the
  :mod:`avocado.utils.software_manager` module, now produces output as
  expected from a script.

* The ``multiplex`` command, an alias to ``variants``, has been
  deprecated for a long time, and has now finally been removed.

Bug Fixes
=========

* When a dry-run is executed, by passing the ``--dry-run`` command
  line option, the proper file name of the test will be shown, instead
  of the file implementing the "fake" :class:`avocado.core.test.DryRun`
  class.

* Users of :mod:`avocado.utils.ssh.Session` as a context manager, would
  have all the exceptions captured and suppressed because of a buggy
  ``__exit__`` implementation.

Utility APIs
============

* The new :mod:`avocado.utils.pmem` module provides an interface for
  manage persistent memory.  It allows for creating, deleting,
  enabling, disabling and re-configuring both namespaces and regions
  depending on supported hardware. It wraps the features present on
  the ``ndctl`` and ``daxctl`` binaries.

* The new :meth:`avocado.utils.ssh.Session.get_raw_ssh_commands` allows
  access to the generated (local) commands, which could be used for advanced
  use cases, such as running multiple (remote) commands in a test.
  See the ``examples/apis/utils/ssh.py`` for an example.

* The :mod:`avocado.utils.network` module received a complete
  overhaul, and provides features for getting, checking and setting
  network information from local and even remote hosts.

* Better documentation for the :mod:`avocado.utils.ssh`,
  :mod:`avocado.utils.cloudinit`, :mod:`avocado.utils.service` and
  other modules.

Internal Changes
================

* The foundation of the :doc:`/blueprints/BP001` has been implemented,
  in the form of the :mod:`avocado.core.future.settings` and by
  adjusting pretty much all of Avocado's code to make use of it.  In
  the near future, this is going to replace :mod:`avocado.core.settings`.

* It's now easier to write a runner script that extends the types
  of runnables supported by the N(ext) Runner.  For an example, please
  refer to ``examples/nrunner/runners/avocado-runner-foo``.

* Many more refactors on the :mod:`avocado.utils.asset` module.
