=========
Inventory has been refactored to be implemented via plugins and now allows for multiple sources. This change is mostly transparent to users.

One exception is the ``inventory_dir``, which is now a host variable; previously it could only have one value so it was set globally. This means you cannot use it early in plays anymore to determine ``hosts:`` or similar keywords.
One exception is the ``inventory_dir``, which is now a host variable; previously it could only have one value so it was set globally.
This means you can no longer use it early in plays to determine ``hosts:`` or similar keywords.
This also changes the behaviour of ``add_hosts`` and the implicit localhost;
because they no longer automatically inherit the global value, they default to ``None``. See the module documentation for more information.
The ``inventory_file`` remains unchanged, as it was always host specific.

notes:
- This module bypasses the play host loop and only runs once for all the hosts in the play, if you need it
to iterate use a with\_ directive.
- This module is also supported for Windows targets.
- Windows targets are supported by this module.
- The alias 'host' of the parameter 'name' is only available on >=2.4
- Since Ansible version 2.4, the ``inventory_dir`` variable is now set to ``None`` instead of the 'global inventory source',
because you can now have multiple sources. An example was added that shows how to partially restore the previous behaviour.
