+# Release 0.2.0

+- **breaking change**: There is now a `std` feature, enabled by default, along
+  with the implication that building *without* this feature makes this a
+  `#[no_std]` crate.
+  - The `Float` and `Real` traits are only available when `std` is enabled.
+  - Otherwise, the API is unchanged, and num-traits 0.1.43 now re-exports its
+    items from num-traits 0.2 for compatibility (the [semver-trick]).
