  `Launchpad-bug #1807870 <https://launchpad.net/bugs/1807870>`_


[1.3.0] - 2018-12-01
--------------------

Added
~~~~~

* Add the --deployment option to commands ``rally task report`` and
  ``rally task export`` that allows to report/export all tasks from defined
  deployment.

* Briefly: the new base image is published at `Docker Hub
  <https://hub.docker.com/r/xrally/xrally>`_
  Detailed story: Long time ago Rally team introduced first docker images which
    were hosted by `rallyforge account at Docker Hub
    <https://hub.docker.com/r/rallyforge/rally/>`_. Due to various
    circumstances we lost access to that account and Docker support restored
    access to it in a strange way (we lost all repositories and could not
    recreate them). That is why Rally team started publishing docker images
    from scratch. The new organization was created -`xRally
    <https://hub.docker.com/r/xrally>`_ . Since we already had plans to move
    OpenStack plugins to the separate repository, we started publishing images
    with in-tree OpenStack plugins to `xrally/xrally-openstack repository
    <https://hub.docker.com/r/xrally/xrally-openstack/>`_. As soon as, a
    separate package for OpenStack plugins was introduced, we switched the
    source of `xrally/xrally-openstack Docker Hub repository
    <https://hub.docker.com/r/xrally/xrally-openstack/>`_ to `rally-openstack
    git repository <http://github.com/openstack/rally-openstack>`_.
    As for Rally 1.0.0 we finally have pure framework without heavy
    dependencies and can start publishing separate images for Rally framework
    itself which can be used as a base image for all plugins.
    New images will be located at `xrally/xrally Docker Hub repository
    <https://hub.docker.com/r/xrally/xrally>`_.

Changed
~~~~~~~

* ``rally --version`` prints version of Rally framework with versions of
  installed plugins instead of printing just version of Rally framework.
* Dockerfile moved from the root directory to ./etc/docker/

Fixed
~~~~~

A floating bug with ``constant_for_duration`` runner.

`Launchpad-bug #1800447 <https://launchpad.net/bugs/1800447>`_

[1.2.1] - 2018-09-27
--------------------

Minor inner fixes

[1.2.0] - 2018-09-19
--------------------

Added
~~~~~

* New validator ``map_keys`` for checking keys of specific argument.
* Support of ElasticSearch 6.x cluster *elastic* exporter.

Changed
~~~~~~~

* Improved validation errors for task component.
* [ElasticSearch exporter] Do not send 'no-name-action' index when the item
  fails after some atomic actions completed and there is a root atomic.
  For example, there is 'wait-for-some-resource-ready' action. It consists of
  a bunch of get requests to update the current status. After specified timeout
  this action can fail if the resource is not in the right state. In such case,
  there is no reason to use 'no-name-action' for saving the error, the parent
  index (i.e 'wait-for-some-resource-ready') will already store it.

[1.1.0] - 2018-08-07
--------------------

Added
~~~~~

* Introducing ``rally env cleanup`` command for performing disaster cleanup.
* New CI jobs for checking compatibility with Python 3.4, 3.6, 3.7 .

Changed
~~~~~~~

* The output of json task result exporter (``rally task report --json``) is
  extended with information about environment where task was executed (new
  ``env_name`` and ``env_uuid`` properties)

* Add the --filter-by option to the command ``rally task detailed``, which
  allows us to show only those workloads which we are interested in (see the
  examples below).
  Examples:

  1. show only failed workloads
     ``rally task detailed --filter-by sla-failures``
  2. show only those workloads which include the next scenario plugin(s)
     ``rally task detailed --filter-by scenarios=scenario1[,scenarios2...]``

* `requirements
  <https://github.com/openstack/rally/blob/1.1.0/requirements.txt>`_ and
  `constraints (suggested versions)
  <https://github.com/openstack/rally/blob/1.1.0/upper-constraints.txt>`_ files
  are updated.

Removed
~~~~~~~

* Disturbing warning message about removing in-tree OpenStack plugins. This
  message became redundant after Rally 1.0.0 when such plugins were removed.
* OpenStack related configuration options for sample file.
* Deprecated in Rally 0.10 ``rally.task.exporter.Exporter`` class in favor of
  ``rally.task.exporter.TaskExporter``.

Fixed
~~~~~

* Building HTML reports for verifications at python 3 environment.
  `Launchpad-bug #1785549 <https://launchpad.net/bugs/1785549>`_

Deprecated
~~~~~~~~~~

* 'async' argument of API method task.abort in favor of 'wait' argument which
  doesn't conflict with a reserved keyword in python 3.7

[1.0.0] - 2018-06-20
--------------------

It finally happened. We are happy to inform you that OpenStack plugins has a
single home - https://github.com/openstack/rally-openstack .
All in-tree plugins are removed now and framework part become more lightweight.

What does it mean for you?!
~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you are interested only in OpenStack plugins, just change the package you
are installing from ``rally`` to ``rally-openstack``. If you have custom
OpenStack plugins which inherits from upstream, change python imports from
``rally.plugins.openstack`` to ``rally_openstack``. That is all.

If you are interested not only in OpenStack, you can start using your favourite
tool for various platforms and systems. Here you can find our first attempts
to seize the world - https://github.com/xrally/xrally-docker and
https://github.com/xrally/xrally-kubernetes.

Changed
~~~~~~~

Since OpenStack plugins were moved to the separate repository, the new release
notes should become light as well, so there is no need in separate pages for
each release. All release notes will be aggregated in
`a single file CHANGELOG.rst
<https://github.com/openstack/rally/blob/master/CHANGELOG.rst>`_.

Also, it is sad to mention, but due to OpenStack policies we need to stop
duplicating release notes at ``git tag message``. At least for now.

Removed
~~~~~~~

* All OpenStack related plugins.

Fixed
~~~~~

* Validation of existing platforms in Python 3 environment.
* Support of testr for verifiers.
