+- The Minimum Supported Rust Version (MSRV) is now 1.60.0
 - `spi`: unify all traits into `SpiReadBus`, `SpiWriteBus` and `SpiBus` (read-write).
 - `spi`: Add `SpiDevice` trait to represent a single device in a (possibly shared) bus, with managed chip-select (CS) pin.
 - `spi`: Clarify that implementations are allowed to return before operations are finished, add `flush` to wait until finished.
