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
