Hermes v1.0.0

August 22nd, 2022

After more than 2 years in the works, this is the first stable release of the Hermes relayer! 🎉

For reaching this milestone, we thank the valuable contributions of over 50 individuals, spread across more than 800 documented & resolved issues. Beside Cosmos-SDK and Tendermint, we are fortunate to maintain some of the most active and intense repository in the Cosmos ecosystem. Most importantly, we thank the relentless work of relayer operators that have already relayed billions worth of value in IBC production networks, and have provided us with invaluable feedback on improving Hermes and raising the overall stability of IBC. Kudos to everyone!

Note for operators

⚠️ If upgrading from Hermes v0.15.0, be aware that this release contains multiple breaking
⚠️ changes to the Hermes command-line interface and configuration.
⚠️ Please consult the UPGRADING document for instructions for more details.

Highlights

• The performance and reliability of the relayer has been greatly improved
• Merged commands keys add and keys restore into single command keys add
  The flag to specify the key name for the CLI command keys add has been changed
  from -n to -k. Restoring a key now takes a file containing the mnemonic as
  input instead of directly taking the mnemonic
• Deprecated gas_adjustment setting in favor of new gas_multiplier setting.
  Check out the upgrading instructions for more details about the new setting.

• Renamed query packet unreceived-packets to query packet pending-sends
  and query packet unreceived-acks to query packet pending-acks

• Added CLI command query channel client which outputs the channel's client state
• Added CLI command query transfer denom-trace which outputs the base denomination and path of a given trace hash
• Dropped the raw prefix from all the tx raw commands

  • tx raw update-client, which is the same as update client
  • tx raw upgrade-client, which is the same as upgrade client
  • tx raw upgrade-clients, which is the same as upgrade clients
  • tx raw create-client, which is the same as create client
• [A new section was added to guide][telemetry-guide] which describes how the new metrics
  can be used to observe both the current state of the relayer and the networks it is connected to
