 ### Changed
 
+- `peripherals = ...` is removed
+- The context in init has removed `cx.device`
 - `cortex-m` set as an optional dependency
 - Moved `cortex-m`-related utilities from `rtic/lib.rs` to `rtic/export.rs`
 - Make async task priorities start at 0, instead of 1, to always start at the lowest priority
