+## 0.4.0
+
+### Added
+
+- re-export the `#[derive(Endian)]` macro from `endian_trait_derive`
+- CI and tests
+- This changelog
+- `Endian` can now derive on discriminant-only (C-like) enums with integer
+    representation. It cannot derive on `#[repr(C)]` enums or data-carrying
+    enums.
+
+### Changed
+
+- pinned Rust version to 1.20.0
+
+### Removed
+
+- implementations of `Endian` for `isize` and `usize`.
+
+## 0.3.0
+
+### Added
+
+- implement `Endian` on `i128`, `u128`, and `[T; N]` for arrays of zero through
+    256
+
+## 0.2.0
+
+### Added
+
+- implement `Endian` on `bool`, `char`, `f32`, `f64`
+
+### Changed
+
+- use stable Rust instead of nightly
+
+## 0.1.1
+
+### Added
+
+- crates.io metadata in `Cargo.toml`
+
+## 0.1.0
+
+### Added
+
+- `Endian` trait, implemented on the integer primitives

 List of notable changes to the custom-derive macro for the `Endian` trait.
 
+## 0.4.0
+
+### Added
+
+- Derive macro now supports bare enums with integer representation.
+
+    The Endian trait can only be derived on enums that are tagged with one
+    `#[repr()]` attribute, and that attribute must be one of the integer
+    primitive types. Any other repr value, or a missing repr, or multiple, will
+    cause a failure.
+
+    Attempting to derive Endian on a bodied enum, such as
+
+    ```rust
+    #[repr(i32)]
+    #[derive(Endian)]
+    enum Bodied {
+        A(i32)
+    }
+    ```
+
+    will abort with an error about a mismatched transmute call.
+
+    TODO: Refine that error message.
