Go: v0.9.1

This release backports into the release/v0.9.x line the feature that added the prehash_compare_key boolean parameter to the top-level ProofSpec. When set to true, this flag causes keys to be consistently compared lexicographically according to their hashes within nonexistence proof verification, using the same hash function as specified by the already-extant prehash_key field.

This is a backwards-compatible change, as it requires opt-in via setting the prehash_compare_key flag to true in the ProofSpec. All existing ProofSpecs will continue to behave identically.

Rust: v0.10.2

This release re-enables no_std support for ProtoJSON Serialize and Deserialize instances, by swapping out pbjson for the no_std-compatible fork informalsystems-pbjson.

Rust: v0.10.1

The only change in this release of the ics23 crate is the addition of a serde feature
which adds ProtoJSON-compatible Serialize and Deserialize instances on all Protobuf definitions via
the pbjson-build crate.

Rust: v0.10.0

This release introduces one single boolean new parameter to the top-level ProofSpec: prehash_compare_key.
When set to true, this flag causes keys to be consistently compared lexicographically according to their hashes
within nonexistence proof verification, using the same hash function as specified by the already-extant prehash_key field.

This is a backwards-compatible change, as it requires opt-in via setting the prehash_compare_key flag to true in the ProofSpec.
All existing ProofSpecs will continue to behave identically.

This version also migrates from using gogo/protobuf to cosmos/gogoproto.
