v0.26.0

Oct 31, 2022

The highlight of this release is the addition of domain types specifically for ABCI. Previously, Rust-based Tendermint application developers would have had to exclusively rely on the generated Protobuf types. Many thanks to @​hdevalence for the heavy lifting on this, and to @​mzabaluev for the porting work after the Tendermint v0.35 retraction!

While we will endeavour to keep this API as stable as possible, we know that we will have to evolve it over the coming months to reduce duplication of functionality and types across the ABCI module and RPC crate, so please expect further breaking changes in subsequent breaking releases.

BREAKING CHANGES

• [tendermint] Added domain types for ABCI (#862)
• [tendermint-proto] Use Bytes for byte array fields of ABCI protobuf types. (#1203)

BUG FIXES

• [tendermint-rpc] The encoding of the hash field for requests to the /block_by_hash endpoint has been changed to base64 (from hex) to accommodate discrepancies in how the Tendermint RPC encodes this field for different RPC interfaces (#942)
• Allow a TrustThresholdFraction of 1
  (#1208)

ENHANCEMENTS

• [tendermint-abci] Deprecate Client::set_option. (#1203)

FEATURES

• [tendermint-rpc] Add support for the /block_by_hash RPC endpoint. See https://docs.tendermint.com/master/rpc/#/Info/block_by_hash for details (#832).

v0.25.0

Sep 23, 2022

This release follows from v0.23.9, with the v0.24 series skipped due to Tendermint Core abandoning the v0.35 and v0.36 releases. As such, it is a non-breaking change, and removes the need to pin one's tendermint-rs dependencies to a specific version (as was the case for the v0.23 series).
