8.1.0

Fixed

• Sending envelopes now properly jumps to next node in query plan, if current one is unreachable.
• Fixed stack overflow when cannot determine field type during struct serialization.
• Properly supporting references during struct serialization.

New

• Many types are now Debug.
• HTTP proxy support via the http-proxy feature.
• InvalidProtocol special error for a case when a node doesn't accept requested protocol during handshake.
• ConnectionPoolConfigBuilder for building configuration easily.
• Configurable heartbeat messages to keep connection alive in the pool.

Changed

• Made protocol enums non-exhaustive for future compatibility.
• Session builders are now async and wait for control connection to be ready before returning a session.
• CBytes::new_empty() -> CBytes::new_null(), CBytes::is_empty() -> CBytes::is_null_or_empty().
• Removed Ord, ParialOrd from QueryFlags.
• Using rustls types exported from tokio-rustls, rather than depending on rustls directly.
• Due to an edge case with reconnecting to a seemingly downed node, internal reconnection handling mechanism has been improved.
• Hidden internal structures, which were public but not usable in any way.
