Good question! Compared to Protocol Buffers and Apache Avro, that each have their own specialised schema languages created by them, for them, JSON BinPack taps into the popular and industry-standard JSON Schema language.

That means that you can use any tooling/approach from the wide JSON Schema ecosystem to manage schema evolution. A popular one from the decentralised systems world is Cambria (https://www.inkandswitch.com/cambria/).

That said, I do recognise that schema evolution tech in the JSON Schema world is not as great as it should be. I'm a TSC member of JSON Schema and a few of us are definitely thinking hard on this problem too and trying to make it even better that the competition.
