@@ -16,6 +16,7 @@ and this project adheres to [Semantic Versioning](http://semver.org/).
 - Added Interruptable trait to Alternate mode pins
 - Added a "low pin count" variant of the f730 chip to the crate features: packages <144 pins don't include a high speed USB PHY
 - Added SPI2_SCK pin for stm32f769i-discovery
+- Fix mass-erase triggering in `flash` on smaller chips
