 - Support cortex-m-rt `v0.7.0` but still allow `v0.6.13` ([#283])
 
+### Fixed
+
+- Fix `can` support. Can would not build for `stm32f302x6` for example.
+  Also support `can` for every chip other than `stm32f301` and `stm32f318`.

 ### Breaking Changes
 
 - Make `rtc` an optional feature. Without that feature `rtcc` as a dependency is
