Hi everyone,
We have released Ansible 1.6.10, which addresses some minor bugs and extended test coverage.
This update is available via PyPi and releases.ansible.com now, and packages for distros will be available as soon as possible.
Thanks!
Just as a quick follow up, this was
(A) a unicode bug related to parsing
(B) a problem with the copy module in certain modes.
Normally we wouldn’t have done a dot release here, but it made sense because we wanted to restore everything to as close-to-perfect after the previous security release series where developing on an embargoed branch and at some speed is always a bit of a tricky thing 
Should be much better now, and unicode tests are greatly enhanced in integration test land to avoid this in the future.
Thanks for barring with us!
