Changelog

Sourced from tokio-serial's changelog.

[5.5.0] 2026-06-15

Added

• serde feature, exposing the Serialize/Deserialize implementations from mio-serial/serialport for the re-exported port configuration types (SerialPortBuilder, DataBits, Parity, etc.). #80 by @​barafael.

Changed

• SerialFramed now reads via tokio_util::io::poll_read_buf instead of a hand-rolled unsafe read loop. #78 by @​paolobarbolini.
• Replaced the futures dependency with the lighter futures-core and futures-sink. No public API change: the implemented Stream/Sink traits are the same re-exported traits. #81 by @​paolobarbolini, closes #73.
• Bumped the Minimum Supported Rust Version to 1.71.0, matching the tokio dependency (the previously documented 1.46.0 was no longer attainable).
• Fixed compiler warnings on Windows.
