*******************************
Ansible-core 2.14 Porting Guide
*******************************
This section discusses the behavioral changes between ``ansible-core`` 2.13 and ``ansible-core`` 2.14.
It is intended to assist in updating your playbooks, plugins and other parts of your Ansible infrastructure so they will work with this version of Ansible.
We suggest you read this page along with `ansible-core Changelog for 2.14 <https://github.com/ansible/ansible/blob/stable-2.14/changelogs/CHANGELOG-v2.14.rst>`_ to understand what updates you may need to make.
This document is part of a collection on porting. The complete list of porting guides can be found at :ref:`porting guides <porting_guides>`.

Playbook
========
* Variables are now evaluated lazily; only when they are actually used. For example, in ansible-core 2.14 an expression ``{{ defined_variable or undefined_variable }}`` does not fail on ``undefined_variable`` if the first part of ``or`` is evaluated to ``True`` as it is not needed to evaluate the second part. One particular case of a change in behavior to note is the task below which uses the ``undefined`` test. Prior to version 2.14 this would result in a fatal error trying to access the undefined value in the dictionary. In 2.14 the assertion passes as the dictionary is evaluated as undefined through one of its undefined values:
.. code-block:: yaml
- assert:
that:
- some_defined_dict_with_undefined_values is undefined
vars:
dict_value: 1
some_defined_dict_with_undefined_values:
key1: value1
key2: '{{ dict_value }}'
key3: '{{ undefined_dict_value }}'
Command Line
============
* Python 3.9 on the controller node is a hard requirement for this release.
* At startup the filesystem encoding and locale are checked to verify they are UTF-8. If not, the process exits with an error reporting the errant encoding. If you were previously using the ``C`` or ``POSIX`` locale, you may be able to use ``C.UTF-8``. If you were previously using a locale such as ``en_US.ISO-8859-1``, you may be able to use ``en_US.UTF-8``. For simplicity it may be easiest to export the appropriate locale using the ``LC_ALL`` environment variable. An alternative to modifying your system locale is to run Python in UTF-8 mode; See the `Python documentation <https://docs.python.org/3/using/cmdline.html#envvar-PYTHONUTF8>`_ for more information.
