+
+## Unreleased - YYYY-MM-DD
+
+### Added
+* **BREAKING**: Blocks now require that arguments and return type implement
+  `objc2_encode::Encode`. This is a safety measure to prevent creating blocks
+  with invalid arguments.
+* Proper GNUStep support using `block-sys`. See that crate for usage.
+* Export `block-sys` as `ffi` module.
+* Blocks now implements `objc2_encode::RefEncode` (and as such can be used in
+  Objective-C message sends).
+
+### Changed
+* **BREAKING**: Forked the project, so it is now available under the name
+  `block2`.
+* No longer depends on `objc_test_utils`.
+
+### Fixed
+* Soundness issues with using empty enums.

+
+Notable changes to this crate will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
+
+## Unreleased - YYYY-MM-DD
+
+### Added
+* **BREAKING**: Add `Encoding::LongDouble`, `Encoding::FloatComplex`,
+  `Encoding::DoubleComplex` and `Encoding::LongDoubleComplex`.
+* Improved documentation.
+* **BREAKING**: Add `RefEncode` trait, which represents types whoose pointers
+  has an encoding. This means you now only have to implement `RefEncode`, and
+  not both `&Encode` and `&mut Encode`.
+* **BREAKING**: Implement `Encode` and `RefEncode` for all basic types (where
+  `T` is properly bound to implement it as well):
+  - Number types (`f32`, `u32`, ...)
+  - `NonZero` integer types
+  - `[T; LEN]` for all `LEN`s
+  - `ManuallyDrop<T>`
+  - `Pin<T>`
+  - `NonNull<T>`
+  - `Option<NonNull<T>>`
+  - `Wrapping<T>`
+  - `*const c_void`
+  - `*mut c_void`
+  - Some `extern "C" fn` pointers
+  - Pointers to pointers
+  - Pointers to pointers to pointers
+  - And so on
+* Add `EncodeArguments` from `objc` crate.
+
+### Changed
+* **BREAKING**: Forked the project, so it is now available under the name
+  `objc2-encode`.
+* **BREAKING**: Made `Encoding` `#[non_exhaustive]`. This will help us in
+  evolving the API while minimizing further breaking changes.
+* Loosen `'static` bounds on references implementing `Encode`.
+* Discourage using `bool::ENCODING`; use `objc2::Bool::ENCODING` instead.
+
+### Removed
+* **BREAKING**: Automatic `*const T: Encode` and `*mut T: Encode` impls when
+  when `&T: Encode` and `&mut T: Encode` was implemented. Implement
+  `T: RefEncode` instead!
+
+
+## [1.1.0] (`objc-encode` crate) - 2019-10-16
+
+### Added
+* Implement `Encode` for arrays with up to 32 elements.
+
+### Changed
+* Simplify internal encoding comparison.
+
+
+## [1.0.0] (`objc-encode` crate) - 2019-03-25
+
+### Added
+* Implement `PartialEq` between `Encoding` and `&str`.
+
+### Changed
+* **BREAKING**: Make `Encoding` an enum instead of a trait, yielding a vastly
+  different design. This makes use of associated constants.
+* **BREAKING**: Rename `Encode::CODE` to `Encode::ENCODING`.
+* Update to Rust 2018.
+
+### Removed
+* `libc` dependency.
+
+
+## [0.0.3] (`objc-encode` crate) - 2017-04-30
+
+### Fixed
+* Compilation on versions prior to Rust `1.15`.
+
+
+## [0.0.2] (`objc-encode` crate) - 2017-02-20
+
+### Added
+* **BREAKING**: `Display` requirement for encodings.
+* Implement `PartialEq` for encodings.
+* Implement `Encode` for pointers when references do.
+
+### Fixed
+* `IndexEncodingsComparator`.
+* Compilation with older Rust versions.
+
+
+## [0.0.1] (`objc-encode` crate) - 2017-02-19

+

+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
+
+## Unreleased - YYYY-MM-DD
+
+### Added
+* **BREAKING**: Added associated `Ownership` type to `INSObject` to specify
+  whether the type can be mutated or not. `NSString` is a prime example of a
+  type that you may never get a `Owned/&mut` reference to, since it is very
+  easy to create two `NSString`s with the same underlying allocation.
+* Added helper `is_empty` methods.
+* Added `INSArray::first_mut` and `INSArray::last_mut`.
+
+### Changed
+* **BREAKING**: Renamed a lot of methods to better match Rusts naming scheme:
+  - `INSArray`
+    - `count` -> `len`
+    - `object_at` -> `get`
+    - `mut_object_at` -> `get_mut`
+    - `shared_object_at` -> `get_retained`
+    - `first_object` -> `first`
+    - `last_object` -> `last`
+    - `object_enumerator` -> `iter`
+  - `INSMutableArray`
+    - `add_object` -> `push`
+    - `insert_object_at` -> `insert`
+    - `replace_object_at` -> `replace`
+    - `remove_object_at` -> `remove`
+    - `remove_last_object` -> `pop`
+    - `remove_all_objects` -> `clear`
+  - `INSDictionary`
+    - `count` -> `len`
+    - `object_for` -> `get`
+    - `key_enumerator` -> `iter_keys`
+    - `object_enumerator` -> `iter_values`
+  - `INSValue`
+    - `value` -> `get`
+    - `from_value` -> `new`
+  - `NSComparisonResult`
+    - `from_ordering` -> `from`
+    - `as_ordering` -> `into`
+  - `NSRange`
+    - `from_range` -> `from`
+    - `as_range` -> `into`
+
+### Fixed
+* **BREAKING**: Marked `INS...` traits as `unsafe` to implement.
+* **BREAKING**: Removed `new` method from `INSObject` since some classes don't
+  want this called. It has been re-added to other `INS...` traits on a case by
+  case basis (in particular not `NSValue`).
+* **BREAKING**: `INSString::as_str` now takes an a reference to
+  `objc2::rc::AutoreleasePool`. This ensure that the returned `&str` is only
+  used while the current autorelease pool is valid.
+
+### Removed
+* **BREAKING**: Removed the `object_struct!` macro. It may be re-added in
+  another form.
+* **BREAKING**: `NSMutableSharedArray<T>` and `NSSharedArray<T>` type
+  definitions. Use `NSMutableArray<T, Shared>` and `NSArray<T, Shared>`
+  instead.
+* **BREAKING**: Removed `Any / 'static` bound on `INSObject`. This allows
+  implementing it for objects that contain lifetimes from the outer scope.
