Release notes zappar.js library

Hi,
is there a relase note information about the zappar.js library updates?

I have seen that different libraries are used in the examples.

https://libs.zappar.com/zappar-threejs/0.2.11/zappar-threejs.js
https://libs.zappar.com/zappar-threejs/0.2.13/zappar-threejs.js

It would be nice to know what are the changes, fixes, features.
Is there the info somewhere and i missed it?
