Maintenance release — supply-chain and CI housekeeping only. No library code or
public API changes.
### Security
- Triaged the pyo3 advisories RUSTSEC-2026-0176 / RUSTSEC-2026-0177 as not
affecting Wickra (vulnerable APIs unreachable from the binding; fix blocked
upstream by rust-numpy pinning pyo3 `^0.28`). Recorded in `deny.toml` and
`osv-scanner.toml`.
### Changed
- Java binding: `central-publishing-maven-plugin` 0.5.0 → 0.10.0.
- CI GitHub Actions bumped to latest (checkout, setup-go, setup-java,
codeql-action, taiki-e/install-action).
- Added a Maven ecosystem to Dependabot.
Version bumped across all manifests/lockfiles via `bump_version.py`; Cargo.lock
refreshed. CHANGELOG `[0.8.9]` filled. Tag/publish to follow on explicit GO.
Version bump `0.8.7` → `0.8.8`.
### Fixed
- R binding: declare `Depends: R (>= 2.10)`, clearing the `R CMD check` "package needs dependence on R (>= 2.10)" warning that the bundled, lazy-loaded `sample_ohlcv` dataset triggers on r-universe / CRAN. (#264)
Bump touches the manual release touchpoints only; docs/webpage version strings are left to `sync-about.yml` on the tag.
Version bump `0.8.6` → `0.8.7`.
### Added
- R binding: a *Getting started* vignette and a synthetic `sample_ohlcv` example dataset, giving new users a runnable, self-contained walkthrough and populating the R-universe Articles and Datasets tabs. The vignette's code is exercised in CI so a broken example is caught before the published build. (#262)
Bump touches the manual release touchpoints only; docs/webpage version strings are left to `sync-about.yml` on the tag.
Version bump `0.8.5` → `0.8.6`.
### Changed
- Package registry metadata for better discoverability (#259):
- R (R-universe): R-universe URL + `X-schema.org-keywords` in `DESCRIPTION`, package logo at `bindings/r/man/figures/logo.png`.
- Python (PyPI): `Documentation` project URL.
- C# (NuGet): package icon via `PackageIcon`.
Ships the metadata so the next PyPI/NuGet publish carries the new fields (R-universe rebuilds from main independently). Bump touches the manual release touchpoints only; docs/webpage version strings are left to `sync-about.yml` on the tag.
Version bump `0.8.4` → `0.8.5`.
### Fixed
- The R binding's golden-fixture parity test now skips gracefully when the shared `testdata/golden` fixtures are not bundled with the package — standalone r-universe / CRAN builds package only `bindings/r`, so the repo-root fixtures are unreachable there (this was failing the r-universe build of 0.8.4). The parity stays enforced by the repository CI, where the fixtures are present. (#257)
Bump touches the manual release touchpoints only (`Cargo.toml`/`Cargo.lock`, Python/Node/Java/C#/R manifests, lockfiles, `SECURITY.md`, `CHANGELOG.md`). docs/webpage version strings are left to `sync-about.yml` on the tag.
Version bump `0.8.3` → `0.8.4`.
Ships the work merged via #254:
### Fixed
- A single non-finite (NaN/inf) tick no longer poisons indicator state — 38 more scalar/pairwise indicators (linear-regression family, rolling quantiles/IQR, `Variance`/`StdDev`-derived stats, `Kurtosis`/`Skewness`, trailing stops, `KalmanHedgeRatio`, `SpreadBollingerBands`, …) now reject non-finite input and return `None`, joining the 16 pairwise indicators fixed earlier.
### Added
- Catalogue-wide property-based invariant harness (`crates/wickra-core/tests/invariants.rs`) asserting `batch == streaming`, `reset == fresh`, and non-finite-input rejection for every indicator and bar-builder.
### Changed
- CI: every job now has a runtime cap and the flaky Node test step auto-retries.
- Documentation accuracy fixes in `SECURITY.md`, `ARCHITECTURE.md`, and `THREAT_MODEL.md`.
Bump touches the manual release touchpoints only (`Cargo.toml`/`Cargo.lock`, Python/Node/Java/C#/R manifests, lockfiles, `SECURITY.md`, `CHANGELOG.md`). docs/webpage version strings are left to `sync-about.yml` on the tag.
Version bump 0.8.2 → 0.8.3, releasing the per-binding throughput benchmark work
(merged in #246).
Bumped via `ScriptHelpers/bump_version.py` across all manual touchpoints —
`Cargo.toml`, `pyproject.toml`, the Node `package.json` + 6 platform packages +
both lockfiles, the Java `pom.xml`s + README, the C# `.csproj`, the R
`DESCRIPTION` — plus `Cargo.lock` (via `cargo build`) and the `CHANGELOG.md`
`[0.8.3]` section and compare URLs.
CHANGELOG `[0.8.3]`:
- Per-binding throughput benchmarks for all 9 targets (BENCHMARKS.md §3).
- C ABI archetype test (`examples/c/archetypes.c`).
`cargo fmt`, `cargo test --workspace --all-features` (all green) and
`cargo clippy --workspace --all-targets --all-features -D warnings` pass. The
docs/webpage version strings are bumped by `sync-about.yml` on the `v*` tag —
not touched here.
Patch release shipping the R WebAssembly build fix (#244): `bindings/r/configure` builds the C ABI from source for `wasm32-unknown-emscripten`, so r-universe's webR build stops failing. Also carries the shared Go badge in `bindings/go/README.md`. Version bumped across all manual touchpoints via `bump_version.py` (incl. DESCRIPTION + csproj, which had drifted before).
Patch release shipping the wickra-go mirror license fix (#239). The release-time Go mirror now includes the dual MIT OR Apache-2.0 license files, so the next published Go module version resolves with a redistributable license on pkg.go.dev. No code changes; all other packages are republished unchanged at 0.8.1.
Bumps the workspace from 0.7.9 to 0.8.0 and adds the release-time mirror of the Go module to a standalone `wickra-go` repository.
## release.yml: `go-mirror` job
Adds a `go-mirror` job (independent of `github-release`, `needs: c-abi-build`) that on every `v*` tag:
- assembles the standalone Go module from `bindings/go` (single-package source + the vendored `include/wickra.h`),
- stages the six prebuilt C ABI libraries from the `c-abi-build` artifacts under `lib/<goos>_<goarch>/` (committed in the mirror, unlike the in-repo `lib/.gitignore`),
- rewrites `go.mod` to `module github.com/wickra-lib/wickra-go`,
- commits and tags the result in `wickra-lib/wickra-go` using the `WICKRA_GO_MIRROR_TOKEN` fine-grained PAT.
This makes `go get github.com/wickra-lib/wickra-go` build with no extra steps, closing the gap where the in-repo `bindings/go` module only built inside a full repository checkout. The mirror is a derived artifact, so its bot commit is intentionally unsigned.
## Version bump 0.7.9 -> 0.8.0
Patch never reaches double digits (`0.7.9` -> `0.8.0`). Touchpoints: `Cargo.toml` (+ `Cargo.lock` via build), `bindings/python/pyproject.toml`, `bindings/node/package.json` + 6 platform `npm/*/package.json` + both `package-lock.json` files, `bindings/java/pom.xml` + `examples/java/pom.xml` + Maven/Gradle snippets in `bindings/java/README.md`, and `CHANGELOG.md`. The C# `Wickra.csproj` (version set per tag) and `bindings/c` (inherits the workspace version) are intentionally untouched.
Tagging `v0.8.0` (which triggers the publish + the new mirror) stays gated on explicit confirmation.
Version bump **0.7.3 → 0.7.4** for the B19 Alt-Chart Bars batch (7 new bar builders, 507 → 514).
Bumps `Cargo.toml` (+ `wickra-core` dep), `Cargo.lock`, `pyproject.toml`, the Node `package.json` and its six platform packages, both `package-lock.json` files, and the CHANGELOG (`[Unreleased]` → `[0.7.4]` with compare URLs).
Version bump **0.7.2 → 0.7.3** for the B18 Risk / Performance batch (9 new indicators, 498 → 507).
Bumps `Cargo.toml` (+ `wickra-core` dep), `Cargo.lock`, `pyproject.toml`, the Node `package.json` and its six platform packages, both `package-lock.json` files, and the CHANGELOG (`[Unreleased]` → `[0.7.3]` with compare URLs).
Version bump for the **v0.6.5** release shipping the **B10 Ehlers / Cycle** family (#199): 452 -> 462 indicators. Bumps workspace + Python/Node/WASM package versions, lockfiles and CHANGELOG. No code changes.
Version bump for the **v0.6.4** release shipping the **B9 Price Statistics** family (#197): 447 -> 452 indicators. Bumps workspace + Python/Node/WASM package versions, lockfiles and CHANGELOG. No code changes.
Version bump for the **v0.6.3** release shipping the **B8 Volume** family (#195): 440 -> 447 indicators. Bumps workspace + Python/Node/WASM package versions, lockfiles and CHANGELOG. No code changes.
Version bump for the **v0.6.2** release shipping the **B7 Trailing Stops** family (#193): 434 -> 440 indicators.
Bumps workspace + Python/Node/WASM package versions, lockfiles and CHANGELOG (cuts the `[0.6.2]` section). No code changes.
Version bump for the **v0.6.0** release (ships the B5 Volatility & Bands batch, #189 — 423 -> 429 indicators).
Bumps version strings across Cargo workspace, pyproject, node package.json + 6 platform packages, both package-lock.json files, and Cargo.lock; CHANGELOG `[Unreleased]` -> `[0.6.0]`. No code changes.
Versioning note: patch never reaches two digits — `0.5.9` rolls to the next minor `0.6.0` (not 0.5.10).
Patch release: streaming/batch perf (SMA, Bollinger, RSI, EMA, ATR; outputs unchanged), cross-library benchmark harness, honest tiered README. No new indicators, no API changes.
Version bump 0.5.6 → 0.5.7 for the **B3 — Trend & Directional** batch (#181):
seven new indicators (`Qstick`, `TtmTrend`, `TrendStrengthIndex`,
`PolarizedFractalEfficiency`, `WavePm`, `GatorOscillator`,
`KasePermissionStochastic`), catalog 413 → 420.
Bumps: workspace `Cargo.toml` + `Cargo.lock`, `bindings/python/pyproject.toml`,
`bindings/node/package.json` + the six `npm/*/package.json` platform manifests,
both `package-lock.json` files, and the `CHANGELOG.md` `[Unreleased]` → `[0.5.7]`
roll with compare URLs.
Release bump `0.5.5 → 0.5.6` for the Momentum Oscillators family deepening
(#179): ten new indicators (DisparityIndex, FisherRsi, Rmi, DerivativeOscillator,
Rsx, DynamicMomentumIndex, IntradayMomentumIndex, StochasticCci, ElderRay, Qqe),
counter now 413.
Version strings only across all manifests + lockfiles; CHANGELOG `[Unreleased]`
rolled to `[0.5.6] - 2026-06-04` with the new compare links.
Release bump `0.5.4 → 0.5.5` for the Moving Averages family deepening
(#177): seven new indicators (`SineWeightedMa`, `GeometricMa`, `Ehma`,
`MedianMa`, `AdaptiveLaguerreFilter`, `GeneralizedDema`, `HoltWinters`),
counter now 403.
Version strings only across all manifests + lockfiles; CHANGELOG `[Unreleased]`
rolled to `[0.5.5] - 2026-06-04` with the new compare links.
Version bump for the 0.5.0 release, which ships the relicense to MIT OR Apache-2.0.
Stacked on #158 (base branch `chore/relicense-mit-apache`) so this PR's diff is the bump only. After #158 merges to main, GitHub retargets this PR to main; merge it, then tag `v0.5.0` to publish.
## Changes
- Bump 0.4.7 -> 0.5.0 across the Cargo workspace, Python `pyproject.toml`, Node `package.json` + 6 platform manifests + 2 lockfiles, and `Cargo.lock`.
- CHANGELOG: cut the [0.5.0] section (the relicense) and add compare URLs.
- SECURITY.md: supported versions 0.4.x -> 0.5.x.
Minor (not patch) bump: a relicense is a significant change. No code changes.
NOTE: do not tag/release until you give the go (irreversible publish to crates.io/PyPI/npm). Suggested merge order: #158 -> this -> tag `v0.5.0` -> then the downstream PRs.
Relicenses Wickra from PolyForm Noncommercial 1.0.0 to the dual, OSI-approved **MIT OR Apache-2.0** (the de-facto Rust convention). Wickra becomes permissive, commercial-use-permitted open source; users may choose either license.
## Changes
- Replace `LICENSE` (PolyForm) with `LICENSE-MIT` + `LICENSE-APACHE` (full texts).
- Cargo: workspace `license = "MIT OR Apache-2.0"` (SPDX) + all 7 sub-crates switched from `license-file.workspace` to `license.workspace`.
- `deny.toml`: drop PolyForm from the allowlist.
- Python: `pyproject.toml` PEP 639 SPDX expression; remove the non-commercial classifier (verified: sdist metadata emits `License-Expression: MIT OR Apache-2.0`).
- Node: `package.json`, the 6 platform manifests and both lockfiles.
- README + Python/Node/WASM binding READMEs, CONTRIBUTING, CITATION.cff, PR template, and the WASM `pkg.license` step in `release.yml`.
- SECURITY.md: refresh supported versions 0.1.x -> 0.4.x.
- CHANGELOG: note the relicense under [Unreleased].
## Notes
- No code changes; metadata/text only. `cargo build` and `cargo deny check licenses` pass locally.
- GitHub will auto-detect "MIT, Apache-2.0" once this lands (currently NOASSERTION).
- Matching downstream changes (org `.github` profile, webpage, docs) are in separate PRs; merge those together with the relicense release so the live sites and org profile do not claim MIT before the packages do.
Version bump for 0.4.5: ships Anchored RSI, Volume Profile, TPO Profile and the Alt-Chart Bars family (Renko/Kagi/Point & Figure). Indicator count 289 -> 295.
Release 0.4.4.
Version bump only — no code changes. Ships the 40 TA-Lib candlestick patterns
(parts 2–9, #132–#141, 249 → 289 indicators) plus the candlestick rejection-
guard coverage tests (#142) that landed on `main` since 0.4.3.
Bumped: workspace `Cargo.toml` (+ `wickra-core` dep) and `Cargo.lock`,
`bindings/python/pyproject.toml`, `bindings/node/package.json` (+ 6 platform
`optionalDependencies`), the 6 `bindings/node/npm/*/package.json`, both
`package-lock.json` files, and `CHANGELOG.md` ([Unreleased] → [0.4.4]).
The LICENSE now carries an Additional Permissions section on top of
PolyForm Noncommercial 1.0.0, so the bare SPDX id no longer describes
it exactly. Update the package manifests to reference the actual file
instead of claiming the unmodified standard:
- Cargo (workspace + all crates): license -> license-file = "LICENSE"
- npm (main + 6 platform packages): LicenseRef-Wickra-Noncommercial-1.0.0
- PyPI: license text notes the additional personal-account permissions
Releases the cross-asset / pairwise indicator family (PR #109):
PairwiseBeta, PairSpreadZScore, LeadLagCrossCorrelation, Cointegration,
RelativeStrengthAB. Indicator count 214 -> 219.
Bumps workspace + binding versions and the CHANGELOG ([Unreleased] ->
[0.4.1]) with the new compare URL.
