-### Support for embedded-hal 1.0
+### Implemented traits
 
-We plan to support embedded-hal 1.0 soon after it is released.
-
-For now, there is preliminary support for alpha/rc versions of embedded-hal, which can
-be enabled with the feature `eh1_0_alpha`. Please note that this support does not
-provide any semver compatibility guarantees: With that feature activated, there
-will be breaking changes even in minor versions of rp2040-hal.
-
-Support for embedded-hal 1.0(-alpha/rc) exists in parallel to support for
-embedded-hal 0.2: Traits of both versions are implemented and can be used
-at the same time.
+This crate aims to implement all traits from embedded-hal, both version
+0.2 and 1.0. They can be used at the same time, so you can upgrade drivers
+incrementally.
