+# 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).
+
+## [1.1.0] - 2025-01-10
+
+### Added
+- **CLI Tool** - Command-line interface for JSON ↔ ASON conversion
+  - Auto-detection of format from file extension or content
+  - `--stats` flag for visual token count comparison with ASCII table
+  - `--delimiter` option for comma/tab/pipe separators
+  - Stdin/stdout support for piping workflows (e.g., `cat data.json | npx ason`)
+  - Comprehensive help documentation with `-h/--help`
+  - Support for `--no-references` and `--no-dictionary` flags
+- **TypeScript Support** - Full type definitions included
+  - `.d.ts` files for ESM (48.2 KB)
+  - `.d.cts` files for CommonJS (48.2 KB)
+  - Full IntelliSense and autocomplete support in VSCode and other IDEs
+  - Proper type exports for both `import` and `require`
+- **Build System** - Integrated tsup for optimized bundling
+  - Minified ESM build (14.5 KB) - 70% smaller than source
+  - Minified CJS build (14.5 KB) for Node.js legacy compatibility
+  - Tree-shaking enabled for smaller bundle sizes
+  - Dual package exports for seamless ESM/CJS interop
+
+### Changed
+- Package now ships with built/minified code instead of source files
+- `package.json` configured with proper `exports` field for ESM/CJS resolution
+- Updated `files` field to include only dist/, src/cli.js, and README.md
+- Repository URL format corrected to use `git+` prefix (eliminates npm publish warning)
+
+### Improved
+- **README** - Premium documentation matching Toon's quality
+  - Head-to-head comparison table: ASON vs Toon showing ASON superiority
+  - ASCII bar charts for visual benchmark comparison
+  - Complete API reference with TypeScript examples
+  - CLI usage guide with real-world examples
+  - Professional badges (npm, TypeScript, License, Node.js)
+  - Detailed table of contents with deep anchor links
+  - "When to use" guide comparing ASON, Toon, JSON, and CSV
+- **Package Distribution** - Optimized for production
+  - Tarball size: 37.8 KB (includes types, CLI, and docs)
+  - Unpacked size: 148 KB
+  - Only 7 files published (down from previous bloat)
+
+### Performance
+- Benchmarks updated showing ASON achieves **+4.94% average token reduction**
+- Toon shows **-6.75% average** (worse than JSON in some cases)
+- ASON wins on **3 out of 4** tested real-world datasets
+- CLI `--stats` flag provides instant compression metrics
+
+## [1.0.0] - 2025-01-10
+
+### Added
+- Initial release of ASON (Aliased Serialization Object Notation)
+- Complete Node.js implementation with SmartCompressor
+- Automatic pattern detection (zero configuration required)
+- Object references for repeated structures (`&obj0`, `&obj1`, etc.)
+- Inline-first value dictionary optimized for LLM readability (`#0`, `#1`, etc.)
+- Uniform array compression with `@keys` notation
+- Path flattening for nested single-property objects
+- Configurable indentation (0, 1, or 2 spaces)
+- Lossless compression with perfect round-trip fidelity
+- Interactive web visualizer with compress/decompress modes
+- Comprehensive documentation site
+- Benchmark suite comparing against Toon and JSON
+- Complete test suite with Jest
+- Community files: CODE_OF_CONDUCT, CONTRIBUTING, SECURITY
+- MIT License
+
+### Performance
+- Achieves 33.26% token reduction on real-world data (28KB JSON)
+- Beats Toon format by 8 tokens (1,808 vs 1,816)
+- Processes ~35ms for compression + decompression cycle
+- Memory efficient: ~10MB for large datasets
+
+### Documentation
+- Web visualizer at `/docs/index.html`
+- Complete API documentation at `/docs/docs.html`
+- Interactive benchmarks at `/docs/benchmarks.html`
+- README with quick start guide
+- Examples in `/nodejs-compressor/examples/`

+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement via GitHub issues.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.

+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+

+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
