v2.1.0-rc1

Highlights

• Add ability to set a MinGasAmount in config file to workaround AnteHandlers that disallow 0 gas. Setting this to a non-zero value (1) is necessary to relay on Evmos.
• Resolves a caching issue where the counterparty connection ID will be empty if a MsgConnectionOpenInit message was observed in the history after the initial connection state was cached by the CosmosChainProcessor.
• Adds begin and end block event parsing. Necessary for ICA.

Summary

This release candidate adds the -p events flag/argument to the rly start command.

This implements a new architecture that drastically reduces the load on RPC nodes. While using this flag has proven to be efficient and effective, it is still in an experimental stage.

v2.0.0-beta4

Overview

v2 of the relayer introduces some new features, several improvements, and bug fixes.

• Moved main relayer logic behind Provider interface which paves the way for non-Cosmos based chains to integrate with the relayer.
• Significant changes to the config format for both chains and paths.
• Move away from channel based paths in favor of connection based paths, where the relayer will attempt to relay on all channels over a given connection.
• Add channel filter for configurable rules used in creating an allow or deny list of channels you want to relay on or avoid.
• Upgrade to ibc-go v3.
• Introduction of Zap for structured logging.
• Improved concurrency model for graceful shutdowns.
• Ability to add and restore keys with coin types other than 118.
• Add ability to fetch chain metadata from the chain-registry via the rly chains add command.
• Fix the rly start command.
• Improvements around new path generation/linking between two chains.
• Dynamic querying for TrustingPeriod used in creating clients, set to be 85% of the chains unbonding time.
