Changed

  • x-ccf-tx-view and x-ccf-tx-seqno response headers have been removed, and replaced with x-ms-ccf-transaction-id. This includes both original fields, separated by a single .. Historical queries using ccf::historical::adapter should also pass a single combined x-ms-ccf-transaction-id header (#2257).
  • Node unique identifier is now the hex-encoded string of the SHA-256 digest of the node's DER-encoded identity public key, which is also used as the node's quote report data. The sandbox.sh script still uses incrementing IDs to keep track of nodes and for their respective directories (#2241).
  • Members and users unique identifier is now the hex-encoded string of the SHA-256 digest of their DER-encoded identity certificate (i.e. fingerprint), which has to be specified as the keyId field for signed HTTP requests (#2279).
  • The receipt interface has changed, /app/receipt?commit=23 is replaced by /app/receipt?transaction_id=2.23. Receipt fetching is now implemented as a historical query, which means that the first reponse(s) may be 202 with a Retry-After header. Receipts are now structured JSON, as opposed to a flat byte sequence, and /app/receipt/verify has been removed in favour of an offline verification sample.
  • ccfapp::get_rpc_handler() now takes a reference to a ccf::AbstractNodeContext rather than ccf::AbstractNodeState. The node state can be obtained from the context via get_node_state().

Removed

  • get_receipt_for_seqno_v1 has been removed. Handlers wanting to return receipts must now use the historical API, and can obtain a receipt via ccf::historical::StatePtr. See the historical query with receipt sample for reference.
  • caller_id endpoint has been removed. Members and users can now compute their unique identifier without interacting with CCF (#2279).
  • public:ccf.internal.members.certs_der, public:ccf.internal.users.certs_der, public:ccf.internal.members.digests and public:ccf.internal.users.digests KV tables have been removed (#2279).
  • view_change_in_progress field in network/status response has been removed (#2288).
