 ## v0.36.0
 
 This release brings substantial performance improvements to the voting power computation within the light client, improves the handling of misformed blocks (eg. with empty `last_commit` on non-first block) when decoding them from Protobuf or RPC responses, and adds missing `serde` derives on some Protobuf definitions.
