 ### Changed
 
- - update `stm32f4` to 0.15.1
- - use `stm32_i2s_v12x` version 0.3, reexport it, and implements requirement for it
- - i2s module don't reuse marker from spi module and define its own.
- - `i2s-audio-out` example updated and now use pcm5102 dac module instead one from discovery board.
- - extend visibility of gpio/marker to crate since i2s module require it.
- - Bump `synopsys-usb-otg` to `0.3.0`
- - Bump `embedded-hal` to `1.0.0-alpha.8`
-
-### Added
- - example of using i2s in out with rtic and interrupt.
