-## Releases
-
-At the moment we are working towards a `1.0.0` release (see [#177]). During this process we will
-release alpha versions like `1.0.0-alpha.1` and `1.0.0-alpha.2`.
-Alpha releases are **not guaranteed** to be compatible with each other.
-They are provided as early previews for community testing and preparation for the final release.
-If you use an alpha release, we recommend you choose an exact version specification in your
-`Cargo.toml` like: `embedded-hal = "=1.0.0-alpha.9"`
-
-See [this guide](docs/version-policy.md) for a way to implement both an `embedded-hal` `0.2.x`
-version and an `-alpha` version side by side in a HAL.

 To support bus sharing, `embedded-hal` provides the `SpiBus` and `SpiDevice` traits. `SpiBus` represents an entire bus,
 while `SpiDevice` represents a device on that bus. For further details on these traits, please consult the

 `embedded-hal` trait implementations for microcontrollers should implement the `SpiBus` trait.
 However, device drivers should use the `SpiDevice` traits, _not the `SpiBus` traits_ if at all possible
