Added

  • Added get_untrusted_host_time_v1 API. This can be used to retrieve a timestamp during endpoint execution, accurate to within a few milliseconds. Note that this timestamp comes directly from the host so is not trusted, and should not be used to make sensitive decisions within a transaction (#2550).
  • Added get_quotes_for_all_trusted_nodes_v1 API. This returns the ID and quote for all nodes which are currently trusted and participating in the service, for live audit (#2511).
  • Added node start-up check for cchost and enclave compatibility, which should both always be from the same release for a single node (#2532).
  • Added a new /node/version endpoint to return the CCF version of a node (#2582).
  • Added a new /node/metrics endpoint which includes the count of active and peak concurrent sessions handled by the node (#2596).
  • Added experimental JavaScript API ccf.host.triggerSubprocess() (#2461).

Changed

  • The curve-id selected for the identity of joining nodes no longer needs to match that of the network (#2525).
  • The per-node session cap behaviour has changed. The --max-open-sessions is now a soft cap on the number of sessions. Beyond this, new sessions will receive a HTTP 503 error immediately after completing the TLS handshake. The existing hard cap (where sessions are closed immediately, before the TLS handshake) is still available, under the new argument --max-open-sessions-hard (#2583).
  • Requests with a url-encoded query string are now forwarded correctly from backups to the primary (#2587).
  • Signed requests with a url-encoded query string are now handled correctly rather than rejected (#2592).
  • Fixed consistency issue between ledger files on different nodes when snapshotting is active (#2607).

Dependency

  • Upgrade OpenEnclave from 0.15.0 to 0.16.1 (#2609)
