 ### Added
 
+- Added the optional `#[simd]` attribute in `fearless_simd_macros` 0.1.0 to annotate SIMD-generic functions. The first argument can be a SIMD token, vector, mask, reference, or user-defined wrapper implementing `ExtractToken`. The core library does not depend on the macro crate. ([#347][], [#383][] by [@Shnatsel][])
 - Added `Native<S>` to `SimdFloatElement` and `SimdIntElement` to select native-width vectors in scalar-generic code ([#378][] by [@Shnatsel][]). 
 - Added the public `ExtractToken` trait for SIMD tokens, vectors, masks, references, and user-defined wrappers.
 - Added `reverse` for all SIMD vector and mask types. ([#356][] by [@Shnatsel][])

-Future versions of Fearless SIMD might increase the Rust version requirement.
-It will not be treated as a breaking change and as such can even happen with small patch releases.
+Future versions of Fearless SIMD might increase the Rust version requirement. This will be accompanied by a minor version bump.
+
+If you require a fixed MSRV, we recommend using Cargo's [MSRV-aware resolver](https://doc.rust-lang.org/edition-guide/rust-2024/cargo-resolver.html) which will not select a version that fails to build.
+We will provide [security backports](fearless_simd/SECURITY.md) to older Rust versions released within the last 3 years.
