@gr36 @iPabloSB The changelog (commit history) is available for each theme over at GitHub. Here's Cactus, for example. I've run a test suite on each theme that checks for:
- Microformat presence
- Custom CSS and Footer support
- Conversation.js inclusion
- RSD and Webmention presence
For now, the test suite mostly runs on my machine and is not designed to be easy to use. But we might pack it up and release it for third-party theme developers to test their own themes. Of course, nothing is stopping you from doing that now, if you feel adventurous. 😊 But it's not officially released yet and unsupported for now.
