v3.0.0

v3.0.0 - 2025-12-19

Breaking change release regarding mTLS and MEV-Share bundles support.

mTLS

This release enforces mTLS for communication with other FlowProxy instances.
As such, existing setups using HAProxy in front of the system API should be
changed, removing such load balancer from the endpoint.

Signature creation and recovery to / from system endpoint has been removed, saving
on CPU cost for compute threads. This means new versions can't communicate with
previous versions because of it.

WARNING

Currently, client authentication works correctly only if all peers have
certificates with different Common Name (CN) field. Otherwise, OpenSSL TLS
acceptor might pick up the first certificate matching a CN, which may well not
be what the client is presenting.

CLI changes

Some CLI arguments have been changed to reflect these changes:

• The optional flags --private-key-pem-file (PRIVATE_KEY_PEM_FILE) and
  --certificate-pem-file (CERTIFICATE_PEM_FILE), originally intended for
  client authentication only, have been removed in favour of dedicated
  client/server variants.
• The flag --client-certificate-pem-file (CLIENT_CERTIFICATE_PEM_FILE) has
  been added. This will be used by clients' TLS connector to authenticate with
  FlowProxy instances of version v2.1.0 that require mTLS. The file must
  contain both certificate and private key, in PEM format.
• The flag --server-certificate-pem-file (SERVER_CERTIFICATE_PEM_FILE) has
  been added. This will be to create the server TLS acceptor.
  instances of version v2.1.0 that require mTLS. The file must
  contain both certificate and private key, in PEM format

Notice that the newly added flags are mandatory. If the same certificate or
key is used for both a client and a server, then the new flags can be set with
the same values.

MEV-Share bundles

Support for MEV-Share bundles has officially been dropped, so they won't be
accepted and processed starting from this release. On BuilderNet, they have
been already deprecated by some weeks.

Miscellaneous

• Now the codebase features Rust 2024 edition
• Formatter both inside justfile and CI have been bumped to nightly-2025-12-18

v1.3.4

Bump prometric dependency.

Full Changelog: v1.3.3...v1.3.4

v2.0.0

What's Changed

This release drops the HTTP server used in FlowProxy for dealing with system
requests. Now only the TCP server exists. It marks a breaking change in
FlowProxy, because backwards compatibility is not maintained anymore.

• The HTTP server on the usual system api port (5544) has been dropped, meaning
  that also the readyz/infoz/livez endpoint are now unsupported as well.
  Healthchecks will be performed by sending a special packet to the TCP server,
  see chainbound/msg-rs#140.
• As mentioned above, all functionality related to infoz endpoint for port
  discovery has been dropped, and the socket address returned from BuilderHub is
  assumed to be for the TCP server.
• The flag --system-listen-addr-tcp (SYSTEM_LISTEN_ADDR_TCP) has been
  dropped.
• The flag --system-listen-addr-http (SYSTEM_LISTEN_ADDR) has been renamed
  to --system-listen-addr, with same environment variable name, and it now is
  used to bind the TCP server.
• The flag --http.client-pool-size (CLIENT_POOL_SIZE) has been removed since
  there are no more HTTP clients used for forwarding orders to peers.
