+# OracleTrace v2.0.0 - Release Notes
+
+**Date:** 2026-04-09
+
+This release consolidates major improvements across the CLI, performance regression workflows, test coverage, and documentation, with a strong focus on practical local usage and CI automation.
+
+## Summary
+
+OracleTrace 2.0.0 introduces:
+
+- New analysis and output controls (`--csv`, `--ignore`, `--top`)
+- CI regression gating (`--fail-on-regression` + `--threshold`)
+- Tracer improvements (including qualified function naming and timing)
+- Automated CLI test coverage with `pytest`
+- Expanded and fully aligned documentation
+
+## Changelog
+
+### Added
+
+- CSV export for trace results (`--csv`)
+- Regex-based filtering for functions/paths (`--ignore`)
+- Top-N summary limiting (`--top`)
+- Regression fail mode for pipelines (`--fail-on-regression`)
+- Configurable regression threshold (`--threshold`)
+- Automated CLI tests with `pytest`
+- CI workflow running tests across multiple Python versions
+- Issue and Pull Request templates for contribution consistency
+
+### Improved
+
+- Clearer total execution timing in tracer output
+- Fully qualified function naming with `co_qualname` for better trace identity
+- More robust baseline vs current comparison flow for regression validation
+- More predictable CLI error and exit behavior for automation
+
+### Documentation
+
+- CLI Reference updated with current flags and usage
+- Examples expanded (CSV export, ignore/top usage, CI regression gate)
+- Quickstart updated with baseline/compare and optional CI gate flow
+- README updated to reflect current features and recommended commands
+- CONTRIBUTING updated to reflect the existing automated test suite
+
+### Fixes / Maintenance
+
+- Test workflow maintenance updates (including runtime matrix adjustments)
+- `.gitignore` update for generated docs paths
+- Maintainer/contributor information updates
+
+## Compatibility and Migration Notes
+
+- Requirement remains: **Python >= 3.10**
+- Existing baseline + compare workflows remain valid
+- No mandatory breaking migration for existing users
+- For CI, recommended command pattern is:
+  - `--fail-on-regression`
+  - `--threshold` tuned to your tolerance (for example `10` or `25`)
+
+## Recommended CI Command
+
+```bash
+oracletrace app.py --json current.json --compare baseline.json --fail-on-regression --threshold 10
+```
+
+## Upgrade
+
+```bash
+pip install --upgrade oracletrace
+```
+
+## Thanks
+
+Thanks to all contributors who helped ship this release across features, docs, tests, and repository infrastructure.
