Lots more gory details in their CHANGELOG and their 2.0 porting guide
This major release includes a major internal rewrite, 200+ new modules (!!), and rainbows and unicorns.
As a heavy user and abuser of Ansible this is an exciting release =)
Congrats Ansible! This is my favorite provisioning toolkit on the market right now. Very happy that their acquisition by RedHat hasn’t kept them from innovating.
