+- `AtomicDevice` now requires enabling feature `portable-atomic` on `thumbv6m-none-eabi` and other targets that don't have atomic CAS.
 - Added the `alloc` feature.
 - Added a new `RcDevice` for I2C and SPI, a reference-counting equivalent to `RefCellDevice`.
 - Migrated `std` feature-gated `std::error::Error` implementations to `core::error::Error`
