Can I revision my templates, styles and components?
Yes. You should revision your Acquia Cohesion assets like other configuration using a service like Git.
Acquia Cohesion renames to Site Studio from version 6.2. Tell me more.
You can create more than one template to provide layout and style alternatives with the use of the template selector.
You can integrate social metadata as you would on a traditional Drupal setup. Information within the layout canvas can not be used as social metadata.
No, there are some known issues when using Acquia Cohesion with AMP, which we are working to resolve.
