+# Change Log
+
+All user visible changes to this project will be documented in this file.
+This project adheres to [Semantic Versioning](http://semver.org/), as described
+for Rust libraries in [RFC #1105](https://github.com/rust-lang/rfcs/blob/master/text/1105-api-evolution.md)
+
+## Unreleased
+
+None.
+
+### Breaking changes
+
+None.
+
+## 1.1.2 - 2021-09-02
+
+- Fix using `pub impl` with `#[async_trait]`.
+
+## 1.1.1 - 2021-06-12
+
+- Fix name collision for extensions on `&T` and `&mut T`. The generated traits
+  now get different names.
+
+## 1.1.0 - 2021-06-12
+
+- Support setting visibility of the generated trait directly on the `impl`
+  block. For example: `pub impl i32 { ... }`.
+- Add `#[ext_sized]` for adding `Sized` supertrait.
+
+## 1.0.1 - 2021-02-14
+
+- Update maintenance status.
+
+## 1.0.0 - 2021-01-30
+
+- Support extensions on bare functions types (things like `fn(i32) -> bool`).
+- Support extensions on trait objects (things like `dyn Send + Sync`).
+
+## 0.3.0 - 2020-08-31
+
+- Add async-trait compatibility.
+
+### Breaking changes
+
+- Other attributes put on the `impl` would previously only be included on the generated trait. They're now included on both the trait and the implementation.
+
+## 0.2.1 - 2020-08-29
+
+- Fix documentation link in Cargo.toml.
+- Use more correct repository URL in Cargo.toml.
+
+## 0.2.0 - 2020-08-29
+
+- Handle unnamed extensions on the same generic type with different type parameters. For example `Option<i32>` and `Option<String>`. Previously we would generate the same name of both hidden traits which wouldn't compile.
+- Support associated constants in extension impls.
+
+### Breaking changes
+
+- Generated traits are no longer sealed and the `sealed` argument previously supported by `#[ext]` has been removed. Making the traits sealed lead to lots of complexity that we didn't think brought much value.
+
+## 0.1.1 - 2020-02-22
+
+- Add support for specifying supertraits of the generated trait [#4](https://github.com/davidpdrsn/extend/pull/4).
+
+## 0.1.0
+
+- Support adding extensions to the ["never type"](https://doc.rust-lang.org/std/primitive.never.html).
+
+### Breaking changes
+
+- Simplify names of traits generates for complex types.
+
+## 0.0.2
+
+- Move "trybuild" to dev-dependency.
+
+## 0.0.1
+
+Initial release.
