Breaking Changes

• Windows is no longer supported.
• JDK 25 required from v26.6.0.

Known Issues

• An extra info message is shown by QUIC, Handshake completed with remote peer id ... which for users is logging noise. This will be removed in the next release. (#10919)

Additions and Improvements

• QUIC p2p protocol enabled by default (Port 9001 ip4, 9091 ip6)
  • Note that this is a new UDP port and should be added to Firewall rules, otherwise incoming QUIC peers will not be able to establish a connection.
• CLI options added for configuration of QUIC
  • --p2p-quic-port (default 9001),
  • --p2p-quic-port-ipv6 (default 9091)
  • --p2p-advertised-quic-port
  • --p2p-advertised-quic-port-ipv6

Bug Fixes

• Prevent RPC rate-limited peers from immediately reconnecting inbound.
• Fixed missing process_cpu_seconds_total metric in the Docker images by adding the jdk.management module to the custom Java runtime.
