* feat: implement Dynamic Time Warping (DTW) functionality
- Added DTW distance computation and optimal warping path functions in Rust.
- Introduced corresponding Python bindings for DTW, DTW_DISTANCE, and BATCH_DTW.
- Enhanced WASM support with a new dtw_distance function.
- Included comprehensive unit tests for DTW functionality, validating against the dtaidistance library and ensuring mathematical properties.
* chore: update ferro-ta version to 1.1.4
- Bumped version number of ferro-ta to 1.1.4 in uv.lock and Cargo.lock files.
- Ensured consistency across package dependencies for the updated version.
- Bumped version numbers across Cargo.toml, Cargo.lock, pyproject.toml, and conda/meta.yaml to 1.1.3.
- Added new features including American option pricing, digital options, extended Greeks, and historical volatility estimators.
- Enhanced documentation and tests for new functionalities.
- Updated CHANGELOG.md to reflect changes for version 1.1.3.
- Bumped version numbers across Cargo.toml, Cargo.lock, pyproject.toml, and conda/meta.yaml to 1.1.2.
- Updated .gitignore to include new WASM build directories for Node.js and web.
- Enhanced WASM npm package to support both Node.js and browser builds with conditional exports.
- Improved CI workflows for WASM publishing and testing.
- Updated documentation to reflect new features and full indicator parity in the WASM package.
- Updated version numbers across Cargo.toml, Cargo.lock, pyproject.toml, and conda/meta.yaml to 1.1.1.
- Added new features and improvements in CHANGELOG.md for version 1.1.1, including full feature parity across Rust, Python, and WASM targets, and numerous new indicator functions in ferro_ta_core.
Update version numbers across Rust, Python, and documentation files to 1.1.0. Enhance the .gitignore to include macOS dSYM files and plans directory. Introduce new dependencies in the Rust core library and update the README to reflect recent performance benchmarks and backtesting engine capabilities. Add new artifacts to the benchmarks manifest and improve documentation for the backtesting engine API.
Align the Rust, Python, WASM, Conda, docs, and lockfile version markers to 1.0.6 so the published artifacts and release automation agree on a single release number.
Add a proper 1.0.6 changelog entry in both CHANGELOG.md and the docs release notes, covering the pre-push gate, expanded Rust and WASM surface, benchmark refresh, and CI hardening work shipped since v1.0.4.
Validate the release preparation with the repo-managed pre-push suite so version, changelog, Rust, Python, docs, WASM, and API-manifest checks all pass before tagging.
Move several hot Python analysis paths to Rust-backed helpers. This adds Rust implementations for backtest strategy signal generation and the core portfolio loop, options and futures payoff aggregation, Greeks aggregation, ratio calculation, trade extraction, chunked close-only indicator runs, and forward-fill helpers. Wire the Python analysis and data modules to prefer these paths, and add coverage for the new batch fast path.
Expand the WASM package to export WMA, ADX, and MFI from ferro_ta_core, refresh the Node examples, benchmarks, and README, and add a Node-vs-Python conformance test so the browser and node surface stays aligned with the main Python package.
Introduce a generated cross-surface API manifest in docs/, along with scripts to rebuild and verify it from source exports. Enforce manifest freshness in the Python and WASM CI workflows so release candidates catch surface drift before push.
Prepare the first patch release after v1.0.0 by finalizing the outstanding release, packaging, and workflow fixes.
This release keeps PyPI and crates.io publishing anchored to CI.yml, splits the large CI workflow into focused rust/python/wasm/docs suites, fixes the ci-complete gate, and updates the release SBOM action pin.
It also switches the npm publish workflow to GitHub OIDC, installs the wasm32 target required for packaging, ensures the WASM npm tarball includes pkg/ artifacts during prepack, and adds a dedicated README plus docs.rs metadata for ferro_ta_core.
Finally, bump all published package versions to 1.0.1 and record the patch release notes in CHANGELOG.md.
Prepare the first public 1.0.0 release and finish the remaining CI hardening work.
Highlights:
- align Python, Rust, WASM, Conda, API, MCP, and docs version metadata to 1.0.0
- promote package metadata to Production/Stable and update stability/versioning docs for the stable series
- move the accumulated Unreleased notes into a dated 1.0.0 changelog section and keep a fresh top-level Unreleased block
- strengthen the changelog checker so it validates a single top-level Unreleased section
- fix the CI/package support mismatch by declaring Python >=3.10 consistently and gating pandas-ta extras to Python 3.12+
- restore Sphinx autodoc compatibility for documented ferro_ta.<module> imports by registering module aliases
- make the TA-Lib benchmark guardrail less flaky by checking median and tail-percentile speedups instead of failing on a single mild outlier
- switch PyPI publishing to OIDC-only trusted publishing and wire the changelog check into the required CI gate
- apply the Ruff-driven cleanup across the Python and test tree and refresh uv/cargo lockfiles
Validated locally:
- python3 scripts/check_changelog.py
- uv run --with ruff ruff check python tests
- uv run --with ruff ruff format --check python tests
- uv lock --check
- sphinx-build -b html docs docs/_build -W --keep-going
- build/install the ferro_ta 1.0.0 wheel successfully
