Ansible 2.7 已发布，命名为“In the Light”。该版本包含许多新特性和改进，主要内容如下：
Allow config to enable native jinja types (#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 (#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 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
