+- [@rubberduck203][@rubberduck203] released the experimental [switch-hal crate][switch-hal], which provides a zero-cost abstraction over Active High/Active Low GPIO, allowing application developers to more clearly express their intent and for drivers to avoid making runtime decisions about driving a line high or low based on the pin's active level.
+- [@rubberduck203][@rubberduck203] has also released the [stm32f3-discovery board support crate][stm32f3-discovery] as an alternative to the unmaintained `f3` crate. 
+- The [stm32f3-discovery-quickstart][stm32f3-discovery-quickstart] template has been updated to utilize both the [stm32f3-discovery board support crate][stm32f3-discovery] and the [switch-hal crate][switch-hal]. It also now includes VS Code tasks for cleaning, building examples, and building in release mode.
