For user convenience we are tracking any such +changes here (as of the 1.0.0 release). + +Should positional arguments for a command need to change, the OpenStackClient +team attempts to make the transition as painless as possible. Look for +deprecation warnings that indicate the new commands (or options) to use. + +Commands labeled as a beta according to :ref:`command-beta` are exempt +from this backwards incompatible change handling. + +Backwards Incompatible Changes +============================== + +.. Carry this section as comments until 4.0 release +.. Release 4.0 +.. ----------- + +.. 1. Change ``volume transfer request accept`` to use new option ``--auth-key`` +.. rather than a second positional argument. + +.. * As of: 4.0 +.. * Remove in: <5.0> +.. * Commit: <tbd> + +Release 3.12.0 +-------------- + +1. Replace ``Display Name`` by ``Name`` in volume list. + + Change column name ``Display Name`` to ``Name`` in ``volume list`` output. + Current ``volume list --name`` command uses ``display_name`` as search_opts + to send to cinder API, and show the result table with ``Display Name`` + as column title. Replace all ``Display Name`` by ``Name`` to be consistent + with other list commands. + + Support a mapping for volume list -c ``Display Name`` (Volume v1 and v2) + and volume create/show -c ``display_name`` (Volume v1) to maintain backward + compatibility until the next major release. + + * In favor of: ``openstack volume list -c Name`` + * As of: 3.12.0 + * Removed in: n/a + * Bug: https://bugs.launchpad.net/python-openstackclient/+bug/1657956 + * Commit: https://review.openstack.org/#/c/423081/ + +Release 3.10 +------------ + +1. The ``network create`` command now requires the ``--subnet`` option when used + with Nova-network clouds. + + * As of: 3.10 + * Commit: https://review.openstack.org/460679 + +2. The positional argument ``<snapshot-name>`` of the ``volume snapshot create`` + command is no longer optional. + + Previously when the ``--volume`` option was + present ``<snapshot-name>`` defaulted to the ``--volume`` value. When the + ``--volume`` option is not present now it defaults to the value of + ``<snapshot-name>``. + + * As of: 3.10 + * Bug: 1659894 + * Commit: https://review.openstack.org/440497 + +Release 3.0 +----------- + +1.

Command `openstack image create` does not update already existing image + + Previously, the image create command updated already existing image if it had + same name. It disabled possibility to create multiple images with same name + and lead to potentially unwanted update of existing images by image create + command. + Now, update code was moved from create action to set action. + + * In favor of: Create multiple images with same name (as glance does). + * As of: 1.5.0 + * Removed in: NA + * Bug: https://bugs.launchpad.net/python-openstackclient/+bug/1461817 + * Commit: https://review.openstack.org/#/c/194654/ + +5. Command `openstack network list --dhcp` has been removed + + The --dhcp option to network list is not a logical use case of listing + networks, it lists agents. Another command should be added in the future + to provide this functionality. It is highly unlikely anyone uses this + feature as we don't support any other agent commands.

Plugin interface change for default API versions + + Previously, the default version was set in the parsed arguments, + but this makes it impossible to tell what has been passed in at the + command line, set in an environment variable or is just the default. + Now, the module should have a DEFAULT_API_VERSION that contains the + value and it will be set after command line argument, environment + and OCC file processing. + + * In favor of: DEFAULT_API_VERSION + * As of: 1.2.1 + * Removed in: NA + * Bug: https://bugs.launchpad.net/python-openstackclient/+bug/1453229 + * Commit: https://review.openstack.org/#/c/181514/ + +7. `image set` commands will no longer return the modified resource + + Previously, modifying an image would result in the new image being displayed + to the user.
