A while back I introduced the concept of schema versions to allow the API to change easily without breaking existing apps. I've bumped the schema version a few times since then and I've been asked to provide a way to access the schema version changes.
That can now be found in
/v2.json (when accessed with a recent schema version, of course).
Here is the change in list format:
/v2.jsonto list all schema versions with a short description.
Thank you for all the bug reports, they've been a big help. If you see any more issues let me know.
