### Added

- Added an `Sse2` level. This is the new baseline for i686-* and x86_64-* targets, replacing `Fallback`. ([#270][] by [@Shnatsel][])
- Added full-vector `swizzle_dyn` and `swizzle_dyn_precise` byte swizzles. `swizzle_dyn` permits implementation-defined results for out-of-range indices, while `swizzle_dyn_precise` always returns zero for them.
- Added trait bounds on `SimdElement`, and introduced the `SimdIntElement` and `SimdFloatElement` subtraits. These allow generic code to access many math and utility operations on the elements of SIMD vector types. ([#302][] by [@danderson][])
