 - The feature gate requires you to select a subvariant if possible. ([#75](https://github.com/stm32-rs/stm32f3xx-hal/pull/75))
 - Split up `stm32f302` into sub-targets `stm32f302xb`,`stm32f302xc`,`stm32f302xd`,`stm32f302xe`
 - Bump `stm32f3` dependency to `0.11.0` ([#97](https://github.com/stm32-rs/stm32f3xx-hal/pull/97))
+- The `stm32f3` reexport is now renamed from `stm32` to `pac` ([#101](https://github.com/stm32-rs/stm32f3xx-hal/pull/101))
