Command Line
============
* The ``ansible-galaxy login`` command has been removed, as the underlying API it used for GitHub auth is being shut down. Publishing roles or
collections to Galaxy via ``ansible-galaxy`` now requires that a Galaxy API token be passed to the CLI via a token file (default location
``~/.ansible/galaxy_token``) or (insecurely) via the ``--token`` argument to ``ansible-galaxy``.

======
* **Upgrading**: If upgrading from ``ansible < 2.10`` or from ``ansible-base`` and using pip, you will need to ``pip uninstall ansible`` or ``pip uninstall ansible-base`` before installing ``ansible-core`` to avoid conflicts.
* Python 3.8 on the controller node is a soft requirement for this release. ``ansible-core`` 2.11 will continue to work with the same versions of Python that ``ansible-base`` 2.10 worked with, however it will emit a warning when running on a controller node with a Python version less than 3.8. This warning can be disabled by setting ``ANSIBLE_CONTROLLER_PYTHON_WARNING=False`` in your environment. ``ansible-core`` 2.12 will require Python 3.8 or greater.
* The configuration system now validates the ``choices`` field, so any settings that currently violate it and are currently ignored will now cause an error.
For example, `ANSIBLE_COLLECTIONS_ON_ANSIBLE_VERSION_MISMATCH=0` will now cause an error (valid choices are 'ignore', 'warn' or 'error').

* Python 3.8 on the controller node is a soft requirement for this release. ``ansible-core`` 2.11 still works with the same versions of Python that ``ansible-base`` 2.10 worked with, however 2.11 emits a warning when running on a controller node with a Python version less than 3.8. This warning can be disabled by setting ``ANSIBLE_CONTROLLER_PYTHON_WARNING=False`` in your environment. ``ansible-core`` 2.12 will require Python 3.8 or greater.
* The configuration system now validates the ``choices`` field, so any settings that violate it and were ignored in 2.10 cause an error in 2.11. For example, `ANSIBLE_COLLECTIONS_ON_ANSIBLE_VERSION_MISMATCH=0` now causes an error (valid choices are ``ignore``, ``warn`` or ``error``).
* The ``ansible-galaxy`` command now uses ``resolvelib`` for resolving dependencies. In most cases this should not make a user-facing difference beyond being more performant, but we note it here for posterity and completeness.
* Python ``module_utils`` imports may now be marked as optional during the module payload build by wrapping the ``import`` statement in a ``try`` or ``if`` block. This allows modules to use ``module_utils`` that may not be present in all versions of Ansible or a collection, and to perform arbitrary recovery or fallback actions during module runtime.
* If you import Python ``module_utils`` into any modules you maintain, you may now mark the import as optional during the module payload build by wrapping the ``import`` statement in a ``try`` or ``if`` block. This allows modules to use ``module_utils`` that may not be present in all versions of Ansible or a collection, and to perform arbitrary recovery or fallback actions during module runtime.

-------------------------
* facts - On NetBSD, ``ansible_virtualization_type`` now tries to report a more accurate result than ``xen`` when virtualized and not running on Xen.
* facts - Virtualization facts now include ``virtualization_tech_guest`` and ``virtualization_tech_host`` keys. These are lists of virtualization technologies that a guest is a part of, or that a host provides, respectively. As an example, a host may be set up to provide both KVM and VirtualBox, and these will be included in ``virtualization_tech_host``, and a podman container running on a VM powered by KVM will have a ``virtualization_tech_guest`` of ``["kvm", "podman", "container"]``.

* The parameter ``filter`` type is changed from ``string`` to ``list`` in the :ref:`setup <setup_module>` module in order to use more than one filter. Previous behaviour (using a ``string``) still remains and works as a single filter.

* inventory plugins - ``CachePluginAdjudicator.flush()`` now calls the underlying cache plugin's ``flush()`` instead of only deleting keys that it knows about. Inventory plugins should use ``delete()`` to remove any specific keys. As a user, this means that when an inventory plugin calls its ``clear_cache()`` method, facts could also be flushed from the cache. To work around this, users can configure inventory plugins to use a cache backend that is independent of the facts cache.
* callback plugins - ``meta`` task execution is now sent to ``v2_playbook_on_task_start`` like any other task. By default, only explicit meta tasks are sent there. Callback plugins can opt-in to receiving internal, implicitly created tasks to act on those as well, as noted in the plugin development documentation.
* The ``choices`` are now validated, so plugins that were using incorrect or incomplete choices will now issue an error if the value provided does not match. This has a simple fix: update the entries in ``choices`` to match reality.

- idrac_user - Issue(192043) Module may error out with the message ``unable to perform the import or export operation because there are pending attribute changes or a configuration job is in progress``. Wait for the job to complete and run the task again.
- ome_configuration_compliance_info - Issue(195592) Module may error out with the message ``unable to process the request because an error occurred``. If the issue persists, report it to the system administrator.
- ome_smart_fabric - Issue(185322) Only three design types are supported by OpenManage Enterprise Modular but the module successfully creates a fabric when the design type is not supported.
- ome_smart_fabric_uplink - Issue(186024) ome_smart_fabric_uplink module does not allow the creation of multiple uplinks of the same name even though this is supported by OpenManage Enterprise Modular. If an uplink is created using the same name as an existing uplink, the existing uplink is modified.

If you use ansible_collections.ansible.netcommon.plugins.module_utils.compat.ipaddress in your collection, you will need to change this to import ipaddress instead. If your content using ipaddress supports Python 2.7, you will additionally need to make sure that the user has the ipaddress package installed.
