Thanks for the suggestion!

As it stands now, I plan to keep things as RSS 2.0 (even though Atom is 
fully supported) just to avoid a massive change on already existing users.

I'm currently working on more QoL updates for the next patch, which 
includes some minor fixes:

- Order feed entries in feed.xml by file creation date
- Include full variables to make upgrade versions easier

BUT - I'd be more than happy to suggest others to your project page on 
the main Shinobi Script repo for those interested in Atom!

Just let me know :)
