v2.0.0-rc1

**This version Introduces a BREAKING change to your config file**
See: config_migration

Overview:

• Interact with the relayer with chain-name rather than chain-ID
• Evmos support
• Improved relaying efficiency
• Improved logging and error handling
• Improved provider implementation

Note: The relayer is being refactored to relay packets and acknowledgments based on block events as opposed to expensive generic queriers. This is still a work in progress.
