+
+## [Unreleased]
+
+Maintained fork of [euclio/spellbound](https://github.com/euclio/spellbound).
+
+### Breaking
+- `Checker::new()` now returns `Result<Self, Error>` instead of panicking when
+  the spellchecker (or hunspell dictionary) is unavailable
+- `SpellingError` now includes UTF-8 byte `start` / `end` offsets into the
+  checked text (in addition to `text()`)
+
+### Added
+- `Error` / `Error::Unavailable`
+- Broader Linux dictionary search paths and `en_US` / `en_GB` fallbacks
+- Word tokenization with offsets on Unix (alphabetic / `'` runs)
+- GitHub Actions CI (Linux, macOS, Windows; fmt; clippy)
+- README documentation for the maintained fork and Linux hunspell setup
+
+### Changed
+- Edition 2021; dropped `lazy_static` / `extern crate`
+- macOS uses `OnceLock` for the shared `NSSpellChecker`
+- Windows COM failures map to `Error` where creating the checker; UTF-16
+  indices convert to UTF-8 byte ranges
+
+### Removed
+- Travis CI and APPVeyor configs
+
+## [0.1.1] - 2020-02-05
+
+Last release from upstream (`euclio/spellbound`).
