Breaking changes

• On querying an unused address, chain context will now return an empty list instead of throwing an exception. #219
• Before v0.9.0, to_cbor will return a hex string by default, and it also accepts an encoding argument. After v0.9.0, it will no longer accept an argument and will only return cbor bytes. To get cbor hex string, users will need to call to_cbor_hex. #232

New Contributors

• @chrissiwaffler made their first contribution in #196
