 ## [Unreleased]
 
+## [0.4.0] - 2023-03-05
+### Added
+- Add ability to parse literals with arbitrary suffixes (e.g. `"foo"bla` or `23px`)
+- Add `suffix()` method to all literal types except `BoolLit`
+- Add `IntegerBase::value`
+- Add `from_suffix` and `suffix` methods to `FloatType` and `IntegerType`
+- Add `FromStr` and `Display` impls to `FloatType` and `IntegerType`
+
+### Changed
+- **Breaking**: Mark `FloatType` and `IntegerType` as `#[non_exhaustive]`
+- **Breaking**: Fix integer parsing for cases like `27f32`. `Literal::parse`
+  and `IntegerLit::parse` will both identify this as an integer literal.
+- **Breaking**: Fix float parsing by correctly rejecting inputs like `27f32`. A
+  float literal must have a period OR an exponent part, according to the spec.
+  Previously decimal integers were accepted in `FloatLit::parse`.
+- Improved some parts of the docs
+
+### Removed
+- **Breaking**: Remove `OwnedLiteral` and `SharedLiteral`
+
