# CHANGELOG
## v0.33.0
*Aug 14th, 2023*
This release bumps `tendermint-rs` to `0.33.0`.
## v0.32.1
*July 31st, 2023*
This release includes default `serde` value for token transfer memos and fixes
the issue with deserialization of `MsgTransfer` and `FungibleTokenPacketData`
types when no memo is present.
### BUG FIXES
- Fix token transfer deserialization for cases with no memo by deriving
`Default` serde for the memo field in `MsgTransfer` and
`FungibleTokenPacketData` types.
([#119](https://github.com/cosmos/ibc-proto-rs/pull/119))
## v0.32.0
*June 14th, 2023*
This release updates the `ibc-go` proto files from version `v5.1.0` to `v6.2.0` which includes the ICA Protobuf definitions.
The version of `borsh` has been downgraded from `v0.10.0` to `v0.9` in order to match `near-sdk-rs` and Solana smart contract frame `anchor`.
### BUG FIXES
- Downgrade `borsh` version from `v0.10.0` to `v0.9`
([#106](https://github.com/cosmos/ibc-proto-rs/pull/104))
### IMPROVEMENTS
- Update `ibc-go` commit from `v5.1.0` to `v6.2.0`
([#106](https://github.com/cosmos/ibc-proto-rs/issues/106))
## v0.31.0
*May 31st, 2023*
This is the final release of `ibc-proto` v0.31.0.
There are no changes from v0.31.0-alpha.2.
For the differences since v0.30.0, please see the changelog entries for v0.31.0-alpha.1 and v0.31.0-alpha.1.
> **Warning**
> This release removes support for `Serialize` and `Deserailize` trait impls being available in `no_std` context.
> See the release notes below and associated issues for more details.
## v0.31.0-alpha.2
*May 3rd, 2023*
This is the second alpha release of `ibc-proto` v0.31.0.
It only updates the `tendermint-proto` version to v0.32.0.
### BREAKING CHANGES
- Update `tendermint-proto` to v0.32.0
([\#99](https://github.com/cosmos/ibc-proto-rs/issues/99))
## v0.31.0-alpha.1
*May 1st, 2023*
This is the first alpha release of `ibc-proto` v0.31.0.
The proto definitions for `cosmos.ics23.v1` messages are now re-exported from the [`ics23`](https://crates.io/crates/ics23) crate under both the `ibc_proto::cosmos::ics23::v1` >
The latter will removed in a subsequent release.
This is nonetheless a breaking change as it may break compilation or trigger warnings in code which relied on these definitions being different than the ones in `ics23`.
Moreover, because the code generated by `pbjson-build` is not `no_std` compatible, the serde annotations on the generated protos are only enabled when the `std` feature of `ibc-proto` is enabled.
### BREAKING CHANGES
- Re-export the `ics23.cosmos.v1` Protobuf definitions from the `ics23` crate instead of including them directly in this crate.
The proto definitions are exported both under the `ibc_proto::cosmos::ics23::v1` module and under the `ibc_proto::ics23` module
in an attempt to preserve backward source compatiblity.
This is a breaking change as it may break compilation or trigger warnings
in code which relied on these definitions being different than the ones in `ics23`.
([\#10](https://github.com/cosmos/ibc-proto-rs/issues/10))
- Derive `Serialize` and `Deserialize` impls compatible with ProtoJSON using `pbjson-build`.
This is a breaking change because the code generated by `pbjson-build` is not
`no_std` compatible. Therefore, the `serde` annotations on the generated protos
are only enabled when the `std` feature of `ibc-proto` is enabled.
([\#95](https://github.com/cosmos/ibc-proto-rs/issues/95))
## v0.30.0
*April 20th, 2023*
This release updates `tendermint-proto` to v0.31.
### BREAKING CHANGES
- Update `tendermint-proto` to v0.31.x
([\#90](https://github.com/cosmos/ibc-proto-rs/pull/90))
## v0.29.0
*April 12th, 2023*
In this update, Protobuf definitions have been included for Interchain Security v1 CCV within
the `ibc_proto::interchain_security::ccv` module.
It should also be noted that the return type of `Protobuf::encode{,_length_delimited}_vec`
has been modified from `Result<Vec<u8>, Error>` to `Vec<u8>`.
Furthermore, the version of `tonic` has been raised from 0.8 to 0.9.
### BREAKING CHANGES
- Remove errors for `encode_vec` and `encode_length_delimited_vec` in
`Protobuf` ([#73](https://github.com/cosmos/ibc-proto-rs/issues/73))
- Update `tonic` to 0.9 and re-generate the protos
([\#79](https://github.com/cosmos/ibc-proto-rs/issues/79))
### FEATURES
- Add Interchain Security v1 CCV Protobuf definitions
([\#76](https://github.com/cosmos/ibc-proto-rs/issues/76))
### BUG FIXES
