 ## [Unreleased]
 
+## [0.1.0] - 2026-04-11
+
 ### Added
-- Initial Rust implementation of codelens
-- High-performance parallel file traversal using `ignore` crate
-- Support for 70+ programming languages
-- Multiple output formats: Console, JSON, CSV, Markdown, HTML
-- Smart directory exclusion based on project type detection
-- Cyclomatic complexity analysis
-- Respects `.gitignore` rules automatically
-- Cross-platform support (Linux, macOS, Windows)
+- **`codelens health`** — Code health scoring with pluggable scoring models
+  - Five dimensions: complexity, function size, comment ratio, file size, nesting depth
+  - Three-level reporting: project, directory, and file
+  - Grades from A (best) to F (worst)
+  - `ScoringModel` trait for custom scoring strategies
+- **`codelens hotspot`** — Change hotspot detection via churn × complexity
+  - Integrates git change frequency with code complexity
+  - Risk levels: HIGH / MED / LOW
+  - Configurable time window (`--since 30d`, `6m`, `1y`, or `YYYY-MM-DD`)
+- **`codelens trend`** — Codebase trend tracking with snapshots
+  - Save snapshots with `--save` and optional `--label`
+  - Compare snapshots with `--compare` (supports `latest`, `latest~N`, date prefix)
+  - Per-language change tracking (Added / Removed / Changed)
+  - Snapshots stored in `.codelens/snapshots/` as JSON
+- Git module (`git/`) for repository integration via system git CLI
+- Full output format support (console, JSON, CSV, Markdown, HTML) for all new commands
+- Interactive HTML reports with Chart.js (radar chart for health, bar charts for hotspot/trend)
+- Colored CLI help with clap Styles and grouped examples
 
 ### Changed
-- Complete rewrite from Python to Rust for 30-50x performance improvement
+- `OutputFormat` trait generalized with `Report` enum to support multiple report types
+- Project description updated to "High performance code analysis tool"
+- P90 percentile used for nesting depth aggregation (instead of max) to reduce outlier impact
 
-## [0.1.0] - YYYY-MM-DD
+### Fixed
+- `--top` argument name conflict between subcommands and `OutputArgs`
+
+## [0.0.3] - 2026-04-10
 
 ### Added
-- First release of the Rust version
+- Byte-level state machine counter for fast line classification
+- TokenTrie and ProcessMask (bloom filter) for unified token matching
+- Precompiled regex patterns with OnceLock caching
+- Criterion benchmarks for byte-level counter
+
+### Changed
+- FileAnalyzer switched to byte-level state machine
+- Per-thread buffer reuse, read bytes instead of String for zero-copy processing
+
+## [0.0.2] - 2026-01-26
+
+### Added
+- Multiline string support for Python, Rust, and other languages
+- Improved filter rules for file exclusion
+
+### Fixed
+- Homebrew formula update workflow
+
+## [0.0.1] - 2026-01-23
+
+### Added
+- Initial Rust implementation of codelens
+- High-performance parallel file traversal using `ignore` crate
+- Support for 70+ programming languages via TOML definitions
+- Multiple output formats: Console, JSON, CSV, Markdown, HTML (with Chart.js)
+- Smart directory exclusion based on project type detection
+- Cyclomatic complexity analysis (function count, nesting depth)
+- Respects `.gitignore` rules automatically
+- Cross-platform support (Linux, macOS, Windows)
+- Configuration file support (`.codelens.toml`)
+- CI/CD pipeline with GitHub Actions
+- Homebrew tap for macOS/Linux installation
