 ### Changed
 
-- Add `Pin::interrupt()` helper method
-- Add restriction for setting pins in alternate mode (`IntoAF`), add docs

-- Add `AFn` type aliases for `Alternate<n>`
-- CI updates + cache
-- Add missing `embedded-hal 1.0` for `DynamicPin`
-- Remove pull resistor from `Input` mode, use `Pull` enum instead, add universal `into_mode` pin converter
