Prerelease: yes

Release notes:

Added

• Support for PreVote optimisation. Nodes understand and are able to respond to PreVote messages, but will not become pre-vote candidates themselves. (#7419, #7445)

Changed

• When the fetch_recent_snapshot behaviour is enabled by the node config, the Joiner will now prefer the peer's snapshot over _any_ local snapshot, regardless of version (#7314).
• Crypto interface for RSA and EC keys (#7425)
• ccf::crypto::PublicKey becomes ccf::crypto::ECPublicKey
• ccf::crypto::KeyPair becomes ccf::crypto::ECKeyPair
• Error-prone inheritance between RSA and EC key classes has been removed.
• RSA keys now don't re-use CSR functionality from EC key interface.

Removed

• Removed the unused experimental ccf.host.triggerSubprocess() JS API
• Removed ACME client and support for ACME-endorsed interfaces (#7414).
• Removed fallback JWT authentication (#7442)
• It is recommended to clean up the old tables for services started before 6.x - check out cleanup_legacy_jwt_records proposal in the default sample constitution.

Fixed

• CheckQuorum now requires a quorum in every configuration (#7375)

Changed

• The snapshot-serving endpoints required for fetch_recent_snapshot behaviour are now disabled-by-default to avoid public DoS requests. They should be enabled on a per-interface basis by adding "enabled_operator_features": ["SnapshotRead"] to the interface's configuration, on an interface with local visibility used for node-to-node join requests.
