+## Version 0.15.0 (2022-02-27)
+
+This is a major feature release with two main changes:
+
+* [#421](https://github.com/mgeisler/textwrap/pull/421): Use `f64`
+  instead of `usize` for fragment widths.
+
+  This fixes problems with overflows in the internal computations of
+  `wrap_optimal_fit` when fragments (words) or line lenghts had
+  extreme values, such as `usize::MAX`.
+
+* [#438](https://github.com/mgeisler/textwrap/pull/438): Simplify
+  `Options` by removing generic type parameters.
+
+  This change removes the new generic parameters introduced in version
+  0.14, as well as the original `WrapSplitter` parameter which has
+  been present since very early versions.
+
+  The result is a simplification of function and struct signatures
+  across the board. So what used to be
+
+  ```rust
+  let options: Options<
+      wrap_algorithms::FirstFit,
+      word_separators::AsciiSpace,
+      word_splitters::HyphenSplitter,
+  > = Options::new(80);
+  ```
+
+  if types are fully written out, is now simply
+
+  ```rust
+  let options: Options<'_> = Options::new(80);
+  ```
+
+  The anonymous lifetime represent the lifetime of the
+  `initial_indent` and `subsequent_indent` strings. The change is
+  nearly performance neutral (a 1-2% regression).
+
+Smaller improvements and changes:
+
+* [#404](https://github.com/mgeisler/textwrap/pull/404): Make
+  documentation for short last-line penalty more precise.
+* [#405](https://github.com/mgeisler/textwrap/pull/405): Cleanup and
+  simplify `Options` docstring.
+* [#411](https://github.com/mgeisler/textwrap/pull/411): Default to
+  `OptimalFit` in interactive example.
+* [#415](https://github.com/mgeisler/textwrap/pull/415): Add demo
+  program to help compute binary sizes.
+* [#423](https://github.com/mgeisler/textwrap/pull/423): Add fuzz
+  tests with fully arbitrary fragments.
+* [#424](https://github.com/mgeisler/textwrap/pull/424): Change
+  `wrap_optimal_fit` penalties to non-negative numbers.
+* [#430](https://github.com/mgeisler/textwrap/pull/430): Add
+  `debug-words` example.
+* [#432](https://github.com/mgeisler/textwrap/pull/432): Use precise
+  dependency versions in Cargo.toml.
