 ## Unreleased
 
-* Add no-std support to all crates except frost-ed448. Note that you don't need
-  to use `default-features = false`; there is no `std` feature that is enabled
-  by default. Also note that it always links to an external `alloc` crate (i.e.
-  there is no `alloc` feature either).
+* Add no-std support to all crates except frost-ed448. To use, do not enable the
+  `std` feature that is enabled by default (i.e. use `default-features =
+  false`); Note that it always links to an external `alloc` crate (i.e. there is
+  no `alloc` feature). When disabling `std`, the only impact in the API is that
+  `Error` will no longer implement the `std::error::Error` trait. This is a
+  breaking change if you are disabling default features but rely on `Error`
+  implementing `std::error::Error`. In that case, simply enable the `std`
+  feature.
