+# 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).
+
+## [1.0.0] - 2025-12-29
+
+### Added
+- **Complete BBL binary format parser** with support for all frame types (I, P, S, H, G, E)
+- **Library API** (`bbl_parser` crate) for programmatic access to parsing and export functions
+- **CSV export** with blackbox_decode-compatible field ordering and formatting
+- **GPX export** for GPS track visualization and mapping applications
+- **Event export** in JSONL format with official Betaflight FlightLogEvent enum mapping
+- **Multi-log support** with automatic detection and separate file generation
+- **Smart export filtering** based on flight duration and gyro activity heuristics
+- **Streaming architecture** for memory-efficient processing of large files (tested: 375K+ frames)
+- **Comprehensive CLI** with configurable output options and batch processing
+- **Feature flags** (`csv`, `json`, `cli`, `serde`) for flexible dependency management
+- **Firmware compatibility** for Betaflight (4.5+), EmuFlight, and INAV
+- **Unit conversions** for voltage (raw to volts) and current (raw to amps)
+- **Energy calculation** with cumulative amperage integration
+- **Betaflight-accurate flag formatting** for flight mode, state, and failsafe phases
+- **GPS coordinate conversion** from NE (north-east) to standard GPS coordinates
+- **Comprehensive test coverage** with 62 unit tests + 8 integration tests
+- **Complete documentation** including README, CRATE_USAGE.md, OVERVIEW.md, and 8 examples
+- **API documentation** with rustdoc comments on all public types and functions
+- **GitHub Actions CI/CD** with multi-platform testing (Linux, Windows, macOS)
+- **Automated release workflow** for crates.io publication with artifact management
+
+### Technical Highlights
+- **Pure Rust implementation** with no external binary dependencies
+- **Production-grade error handling** using `anyhow::Result<T>` throughout public API
+- **Type-safe design** with minimal unsafe code
+- **Cross-platform support** verified on Ubuntu, Windows, and macOS
+- **Dual licensing:** AGPL-3.0-or-later (open source) + commercial option available
+
+### Performance
+- Efficiently processes large blackbox logs via streaming architecture
+- Tested on files up to 375K+ frames (21 MB) in under 7 seconds
+- Memory-efficient frame processing with selective storage for analysis
+
+### Compatibility
+- **Input formats:** .BBL, .BFL, .TXT (case-insensitive)
+- **Firmware versions:** Betaflight 4.0+, EmuFlight, INAV
+- **Output formats:** CSV, GPX, JSONL event logs
+- **Binary compatibility:** Output matches blackbox_decode reference implementation
+
+### Documentation
+- Extensive project documentation (README.md, OVERVIEW.md, CRATE_USAGE.md)
+- Frame format specifications in FRAMES.md
+- Usage examples for CSV, GPX, and event exports
+- Contribution guidelines and commercial licensing information
+
+---
+
+## Future Roadmap
+
+### Planned for 1.1.0
+- IMU angle computation (roll, pitch, yaw) from gyro/accelerometer/magnetometer data
+- Extended unit conversions (altitude, speed, rotation rates, acceleration)
+- GPS data integration into main CSV output
+- Enhanced loop timing statistics and frame distribution analysis
+- Parallel frame processing for multi-log files
+
+### Planned for 1.x series
+- Advanced filtering options for specialized analysis
+- Raw mode output (unprocessed sensor values)
+- Current meter simulation improvements
+- Extended firmware version testing coverage
+
+---
+
+## Known Limitations & Future Work
+
+The following are not blocking 1.0.0 but may be addressed in future releases:
+
+- IMU simulation features not yet implemented
+- Some unit conversion types not yet available (altitude, speed, rotation rates)
+- GPS data is exported separately (.gps.gpx) rather than integrated into CSV
+- Raw sensor value export mode not available
+- Some `.unwrap()` calls in test/example code (critical paths use proper Result handling)
+
+---
+
+## Acknowledgments
+
+This project is built on extensive analysis of:
+- [Betaflight blackbox-log-viewer](https://github.com/betaflight/blackbox-log-viewer)
+- [Betaflight blackbox-tools](https://github.com/betaflight/blackbox-tools)
+
+The implementation ensures compatibility with established blackbox format specifications
+while providing the benefits of a modern, type-safe Rust library.
+

+
+## Version History
+
+- **1.0.0** (2025-12-29) - First stable release
+- **0.9.0** (2025-08+) - Development releases leading up to 1.0.0
