======

Release Summary

• --------------

| Release Date: 2018-10-04
| `Porting Guide
<https://docs.ansible.com/ansible/devel/porting_guides.html>`__

Major Changes

• ------------
• Allow config to enable native jinja types

(https://github.com/ansible/ansible/pull/32738)

• Extends `module_defaults` by adding a prefix to defaults `group/` which

denotes a builtin or user-specified list of modules, such as `group/aws` or
`group/gcp`

• New keyword `ignore_unreachable` for plays and blocks. Allows ignoring

tasks that fail due to unreachable hosts, and check results with `is
unreachable` test.

• New yumdnf module defines the shared argument specification for both yum

and dnf modules and provides an entry point to share code when applicable

• Remove support for simplejson

(https://github.com/ansible/ansible/issues/42761)

• Support for running an Ansible controller with Python-2.6 has been

dropped. You can still manage machines which use Python-2.6 but you will
have to manage them from a machine which has Python-2.7 or Python-3.5 or
greater installed. See the `porting guide
<https://docs.ansible.com/ansible/devel/porting_guides/porting_guide_2.7.html>`_
if you need more information.

• new yum action plugin enables the yum module to work with both yum3 and

dnf-based yum4 by detecting the backend package manager and routing
commands through the correct Ansible module for that python API

• yum and dnf modules now at feature parity

Minor Changes

• ------------
• ActionBase - removed deprecated _fixup_perms method

(https://github.com/ansible/ansible/pull/44320)

• Add `is_boto3_error_code` function to `module_utils/aws/core.py` to make

it easier for modules to handle special AWS error codes.

• Add use_backend to yum module/action plugin
• Added PrivilegeUtil PowerShell module util to easily control Windows

Privileges in a process

• Added capability to skip ssl verification on zabbix host with dynamic

inventory

• Added inventory.any_unparsed_is_failed configuration setting. In an

inventory with a static hosts file and (say) ec2.py, enabling this setting
will cause a failure instead of a warning if ec2.py fails.

• Added new filter to generate random MAC addresses from a given string

acting as a prefix. Refer to the appropriate entry which has been added to
user_guide playbook_filters.rst document.

• Added the from_yaml_all filter to parse multi-document yaml strings.

Refer to the appropriate entry which as been added to user_guide
playbooks_filters.rst document.

• Ansible-2.7 changes the Ansiballz strategy for running modules remotely

so that invoking a module only needs to invoke python once per module on
the remote machine instead of twice.

• Better error handling for depsolve and transaction errors in DNF
• Changed the prefix of all Vultr modules from vr to vultr

(https://github.com/ansible/ansible/issues/42942).

• Enable installroot tests for yum4(dnf) integration testing, dnf backend

now supports that

• Explicit encoding for the output of the template module, to be able to

generate non-utf8 files from a utf-8 template.
(https://github.com/ansible/proposals/issues/121)

• File locking feature added, making it possible to gain exclusive access

to given file through module_utils.common.file.FileLock
(https://github.com/ansible/ansible/issues/29962)

• Fix dnf handling of autoremove to be compatible with yum
• Fix timer in exponential backoff algorithm in vmware.py.
• Fixed group action idempotent transactions in dnf backend
• Fixed group actions in check mode to report correct changed state
• GCP Modules will do home path expansion on service account file paths
