+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+### Fixed
+- `--no-color` and `NO_COLOR` now correctly suppress all ANSI codes. Plain
+  `.red()` / `.green()` etc. emit codes unconditionally; switched everything to
+  `if_supports_color()` which respects the owo-colors override system.
+
+## [0.1.1] - 2026-03-15
+
+### Added
+- Interactive fix mode: resolver control loop with IO abstraction and mock-driven tests
+- Filesystem operation layer with `--dry-run` support
+- `--batch-confirm` flag to collect all decisions then confirm before applying
+- Safety confirmation layer for destructive actions (remove)
+- Fuzzy candidate search with Levenshtein distance, path similarity, and depth penalty scoring
+- Configurable ignore patterns (`-I`) propagated to scanner and fuzzy walker
+- Cross-filesystem and loop-detection warnings
+- CI lint workflow
+- Release profile with LTO, single codegen unit, and stripped binaries
+
+### Changed
+- Replaced subprocess-based resolution with native Rust implementation
+
+## [0.1.0] - 2026-03-13
+
+### Added
+- Initial release
+- Recursive broken symlink scanner
+- Reports dead target path for each broken link
+- Basic `--list` and `--path` flags
+- Fix for correctly identifying broken symlinks (not all symlinks)
