    (#4224)

IMPROVEMENTS

• General
  • Improve detection of Tendermint/CometBFT compatibility
    mode when a chain runs a non-standard version
    (#4178)
• Relayer Library
  • Use CCV consumer ID to submit misbehaviour messages
    (#4153)
  • Improve log message when broadcasting redundant packet and set it
    to INFO instead of ERROR.
    (#4252)
• Integration Test Framework
  • Update the versions of the following simd running the integration tests in the CI:

  • From v6.3.0 to v6.3.1

  • From v7.4.0 to v7.8.0

  • From v9.0.0-beta.1 to v9.0.0-rc.0

    (#4202)

  • Update the version of Gaia running the integration tests in the CI from v18.1.0
    to v20.0.0 (#4204)

v1.10.3

September 2nd, 2024

This release fixes an issue where Hermes could not connect to gRPC servers over TLS. Additionally, this release also fixes a bug in the clear packet CLI where the excluded_sequences configuration option was not always taken into account.

Furthermore, Hermes now uses abci_query instead of gRPC for some queries, for instance for querying staking parameters and service configuration during health checks, and when retrieving version information.

v1.10.2

August 14th, 2024

This release brings significant performance improvements and introduces a new configuration options for better control over packet clearing. Enhancements include faster startup times through optimized queries and the introduction of a clear_limit setting for packet clearing. Additionally, bug fixes and updates to the integration test framework ensure greater stability and compatibility across various environments.

BUG FIXES

• Relayer Library
  • Fix the memo_overwrite configuration to correctly apply the
    overwrite if it is configured.
    (#4104)
• Telemetry & Metrics
  • Fix the dynamic_gas_queried_success_fees Prometheus metric name.
    (#4104)

IMPROVEMENTS

• Relayer Library
  • Add a new configuration clear_limit to specify the maximum number
    of packets cleared every time packet clearing is triggered.
    Defaults to 50.
    (#4071)
  • Paginate results of query_packet_commitments and query_packet_acknowledgements
    queries to speed up the scanning phase.
    (#4101)
  • Use the ibc.core.connection.v1.ConnectionParams gRPC query to retrieve maxExpectedTimePerBlock
    and check it against the configured max_block_time instead of using the /genesis endpoint.
    This improves both startup times and reliability for most chains.
    (#4143)
• Integration Test Framework
  • Update the version of Gaia running the integration tests in the CI from v17.2.1
    to v18.1.0 (#4114)

    to v23.0.0 (#4117)
  • Update the version of Migaloo Chain running the integration tests in the CI from v4.1.3
    to v4.2.0 (#4118)

  version of tendermint-rs from v0.37.0 to v0.38.1.
  (#4093)

IMPROVEMENTS

• Integration Test Framework
  • Add the features packet-forward and ica to enable
    Packet Forward Middleware and ICA when running tests with Osmosis
    (#3195)
