0.15.0

  • Use web-time instead of instant. See PR 5347.

0.14.1

  • Add BandwidthTransport, wrapping an existing Transport, exposing Prometheus bandwidth metrics. See also SwarmBuilder::with_bandwidth_metrics. See PR 4727.

0.14.0

  • Add metrics for SwarmEvent::{NewExternalAddrCandidate,ExternalAddrConfirmed,ExternalAddrExpired}. See PR 4721.

0.13.1

  • Enable gossipsub related data-type fields when compiling for wasm. See PR 4217.

0.13.0

  • Previously libp2p-metrics::identify would increase a counter / gauge / histogram on each received identify information. These metrics are misleading, as e.g. they depend on the identify interval and don't represent the set of currently connected peers. With this change, identify information is tracked for the currently connected peers only. Instead of an increase on each received identify information, metrics represent the status quo (Gauge).

    Metrics removed:

    • libp2p_identify_protocols
    • libp2p_identify_received_info_listen_addrs
    • libp2p_identify_received_info_protocols
    • libp2p_identify_listen_addresses

    Metrics added:

    • libp2p_identify_remote_protocols
    • libp2p_identify_remote_listen_addresses
    • libp2p_identify_local_observed_addresses

    See PR 3325.

  • Raise MSRV to 1.65. See PR 3715.

  • Replace libp2p_swarm_connections_closed Counter with libp2p_swarm_connections_duration Histogram which additionally tracks the duration of a connection. Note that you can use the _count metric of the Histogram as a replacement for the Counter. See PR 3927.

  • Remove the pong_received counter because it is no longer exposed by libp2p-ping. See PR 3947.
