## [0.2.3] - 2025-10-08
[View changes](https://github.com/swaits/dagx/compare/v0.2.2...v0.2.3)
### Added
- **Optional tracing support** via `tracing` feature flag
- Zero-cost when disabled (literally 0ns overhead - code removed at compile time)
- Structured logging at INFO, DEBUG, TRACE, and ERROR levels
- Instrumentation for DAG construction, execution, and error paths
- New example: `examples/tracing_example.rs` demonstrating usage
- Comprehensive test coverage in `tests/tracing/` for both with/without feature
- Follows same pattern as tokio/hyper for performance-critical libraries
- Updated documentation in README.md and lib.rs
### Changed
- Improved `examples/04_parallel_computation.rs` to actually prove parallelism
- Now compares parallel vs sequential execution with timing measurements
- Calculates and displays speedup ratio (e.g., "4.0x faster")
- Clarifies difference from basic fan-in pattern in 03_fan_in.rs
- Added warnings for debug builds with low speedup
### Fixed
- Fixed broken ASCII diagram in `examples/04_parallel_computation.rs`
## [0.2.2] - 2025-10-07
