Update the API

[Tamriel]

The JSON CRDT paper was updated: "we have slightly refined the API, improved the clarity of explanations, and added some more examples".
It would be great if the crjdt code will be updated to the paper :-)

Agreed! Do you know which parts of the API were changed?

Fig. 7 in the new paper has now
EXPR.insertAfter(v) instead of EXPR.insert(v)
EXPR.get(key) instead of EXPR[key]
EXPR.idx(i) instead of EXPR.iter and EXPR.next.
The rules for evaluating IDX are found at the bottom right of page 7. They replace the ITER rules.

This is great, thanks @Tamriel!
