When ansible 2.0 was released there were some changes in playbook
handling made. For this reason, we created a backwards compatible
package with ansible 1.9 to ease the transition for those that needed
more time to adjust their playbooks.
Late last year it looked like there would be a final release in the 1.9
series addressing some security issues. However, the most recent round
of security issues found in 2.x are difficult to impossible to
backport to 1.9 so there will not be a final 1.9 release.
Since it has now been 1 year since ansible 2.0 was released, and since
ansible 1.9 has known security vulnerabilities, backporting fixes is
impossible, we will be retiring the ansible1.9 package from EPEL.
All ansible 1.9 users are urged to update to 2.x as soon as possible.
