• Remove __del__ trashcan usage for structs with gc=False (#369).
• Support overriding __setattr__ in Struct types (#376).
• Support encoding large integers in JSON (#378).
• Fix a memory leak when msgpack decoding variable length tuples with more than 16 elements (#380).
• Remove JSON compatibility checks when constructing a msgspec.json.Decoder. Trying to decode messages into types that JSON doesn't support will now error at decode time, rather than when the decoder is constructed (#381).
