## [1.0.0] - 2025-12-29
9+
10+
### Added
11+
- **Complete BBL binary format parser** with support for all frame types (I, P, S, H, G, E)
12+
- **Library API** (`bbl_parser` crate) for programmatic access to parsing and export functions
13+
- **CSV export** with blackbox_decode-compatible field ordering and formatting
14+
- **GPX export** for GPS track visualization and mapping applications
15+
- **Event export** in JSONL format with official Betaflight FlightLogEvent enum mapping
16+
- **Multi-log support** with automatic detection and separate file generation
17+
- **Smart export filtering** based on flight duration and gyro activity heuristics
18+
- **Streaming architecture** for memory-efficient processing of large files (tested: 375K+ frames)
19+
- **Comprehensive CLI** with configurable output options and batch processing
20+
- **Feature flags** (`csv`, `json`, `cli`, `serde`) for flexible dependency management
21+
- **Firmware compatibility** for Betaflight (4.5+), EmuFlight, and INAV
22+
- **Unit conversions** for voltage (raw to volts) and current (raw to amps)
23+
- **Energy calculation** with cumulative amperage integration
24+
- **Betaflight-accurate flag formatting** for flight mode, state, and failsafe phases
25+
- **GPS coordinate conversion** from NE (north-east) to standard GPS coordinates
26+
- **Comprehensive test coverage** with 62 unit tests + 8 integration tests
27+
- **Complete documentation** including README, CRATE_USAGE.md, OVERVIEW.md, and 8 examples
28+
- **API documentation** with rustdoc comments on all public types and functions
29+
- **GitHub Actions CI/CD** with multi-platform testing (Linux, Windows, macOS)
30+
- **Automated release workflow** for crates.io publication with artifact management
31+
32+
### Technical Highlights
33+
- **Pure Rust implementation** with no external binary dependencies
34+
- **Production-grade error handling** using `anyhow::Result<T>` throughout public API
35+
- **Type-safe design** with minimal unsafe code
36+
- **Cross-platform support** verified on Ubuntu, Windows, and macOS
37+
- **Dual licensing:** AGPL-3.0-or-later (open source) + commercial option available
38+
39+
### Performance
40+
- Efficiently processes large blackbox logs via streaming architecture
41+
- Tested on files up to 375K+ frames (21 MB) in under 7 seconds
42+
- Memory-efficient frame processing with selective storage for analysis
43+
44+
### Compatibility
45+
- **Input formats:** .BBL, .BFL, .TXT (case-insensitive)
46+
- **Firmware versions:** Betaflight 4.5+, EmuFlight, INAV
47+
- **Output formats:** CSV, GPX, JSONL event logs
48+
- **Binary compatibility:** Output matches blackbox_decode reference implementation
49+
50+
### Documentation
51+
- Extensive project documentation (README.md, OVERVIEW.md, CRATE_USAGE.md)
52+
- Frame format specifications in FRAMES.md
53+
- Usage examples for CSV, GPX, and event exports
54+
- Contribution guidelines and commercial licensing information
55+

## Future Roadmap
59+
60+
### Planned for 1.1.0
61+
- IMU angle computation (roll, pitch, yaw) from gyro/accelerometer/magnetometer data
62+
- Extended unit conversions (altitude, speed, rotation rates, acceleration)
63+
- GPS data integration into main CSV output
64+
- Enhanced loop timing statistics and frame distribution analysis
65+
- Parallel frame processing for multi-log files
66+
67+
### Planned for 1.x series
68+
- Advanced filtering options for specialized analysis
69+
- Raw mode output (unprocessed sensor values)
70+
- Current meter simulation improvements
71+
- Extended firmware version testing coverage
72+
73+
---
74+
75+
## Known Limitations & Future Work
76+
77+
The following are not blocking 1.0.0 but may be addressed in future releases:
78+
79+
- IMU simulation features not yet implemented
80+
- Some unit conversion types not yet available (altitude, speed, rotation rates)
81+
- GPS data is exported separately (.gps.gpx) rather than integrated into CSV
82+
- Raw sensor value export mode not available
83+
- Some `.unwrap()` calls in test/example code (critical paths use proper Result handling)
84+

## Acknowledgments
88+
89+
This project is built on extensive analysis of:
90+
- [Betaflight blackbox-log-viewer](https://github.com/betaflight/blackbox-log-viewer)
91+
- [Betaflight blackbox-tools](https://github.com/betaflight/blackbox-tools)
92+
93+
The implementation ensures compatibility with established blackbox format specifications
94+
while providing the benefits of a modern, type-safe Rust library.
