Python was versioned and tagged separately from the Rust, Java, and
Node.js SDKs, and had drifted three minor versions ahead (0.36 vs 0.33).
Users had no way to tell which Python version corresponded to which Rust
or Node release, and the gap had no meaning behind it.
This unifies the two tracks so there is one version and one tag for all
four SDKs.
## Version
The shared version is set to `0.37.0-beta.0`. Python continues its own
sequence (highest published: 0.36 → 0.37) while Rust, Java, and Node.js
jump 0.33 → 0.37 to meet it. Picking Python's next minor means Python
users see no discontinuity at all, and only the other SDKs skip forward.
Note that `main` trails the `release/v0.32` branch on both lines (main
is at 0.32.0-beta.3 / 0.35.0-beta.3; the release branch carries
0.33.0-beta.0 / 0.36.0-beta.0), so 0.37 is chosen to clear the highest
tag on either branch. Every index stays monotonic:
| index | publishes | last published | next |
|---|---|---|---|
| PyPI | stable only | 0.34.0 | 0.37.0 |
| Fury | previews | 0.36.0b0 | 0.37.0-beta.1 |
| npm | both | 0.33.0-beta.0 | 0.37.0-beta.1 |
| crates.io | stable only | 0.31.0 | 0.37.0 |
| Maven | both | 0.33.0-beta.0 | 0.37.0-beta.1 |
A one-time jump for three SDKs, versus explaining the offset
indefinitely.
## Mechanism
* `python/.bumpversion.toml` is removed. `python/Cargo.toml` — the
source of the Python package version, since `pyproject.toml` declares
`dynamic = ["version"]` — becomes a tracked file of the root config. Its
`cargo update -p lancedb-python` pre-commit hook is dropped as
redundant: `ci/update_lockfiles.sh` already refreshes every workspace
member version in `Cargo.lock`.
* `pypi-publish.yml` triggers on `v*` instead of `python-v*`, so one tag
releases all four packages. `ci/bump_version.sh` and
`make-release-commit.yml` lose their now-dead tag-prefix and
per-language plumbing, including the `python` / `other` dispatch inputs.
* The two byte-identical GH release jobs in `npm-publish.yml` and
`pypi-publish.yml` are replaced by a single `gh-release.yml`. One
release per tag, named `LanceDB vX.Y.Z`, instead of separate "Python
LanceDB" and "Node/Rust LanceDB" releases for the same commit.
The trade-off: there is no longer a way to ship a Python-only patch
without also releasing crates.io, Maven, and npm. That is the cost of
making drift structurally impossible.
## Beta releases marked "Latest" (#3666)
Both GH release jobs used:
```yaml
prerelease: ${{ contains('beta', github.ref) }}
```
The arguments are reversed. `contains(search, item)` asks whether
*`search`* contains *`item`*, so this evaluated "does the literal string
`'beta'` contain `refs/tags/python-v0.35.0-beta.2`?" — always `false`.
Every beta was published as a full release, and GitHub awards "Latest"
to the newest non-prerelease.
The new workflow derives the flag from the parsed version rather than
the raw ref, and sets `make_latest` explicitly:
```yaml
prerelease: ${{ steps.extract_version.outputs.prerelease }}
make_latest: ${{ steps.extract_version.outputs.prerelease == 'false' }}
```
npm was never affected (`--tag preview` uses correct bash), and PyPI
already excludes pre-releases from resolution.
This only fixes releases published from here on. Already-published betas
need a one-time backfill:
```shell
gh api --paginate /repos/lancedb/lancedb/releases \
--jq '.[] | select(.prerelease == false) | select(.tag_name | test("beta")) | .id' \
| xargs -I{} gh api -X PATCH /repos/lancedb/lancedb/releases/{} -F prerelease=true
```
## Verification
Ran `ci/bump_version.sh` end-to-end against this branch with the release
tooling installed:
* `preview` → tags `v0.37.0-beta.1` (previous tag `v0.33.0-beta.0`
detected, `pre_n` bump)
* `stable` → tags `v0.37.0`
* Both paths update `.bumpversion.toml`, `rust/lancedb/Cargo.toml`,
`nodejs/Cargo.toml`, `python/Cargo.toml`, `nodejs/package.json`, the 7
`nodejs/npm/*/package.json` files, both Java poms, and
`docs/src/java/java.md` together
* `check_breaking_changes.py` resolves the last stable as `v0.31.0`, so
the minor-version gate passes
All five touched workflows parse as valid YAML and the pre-commit hooks
pass.
## Notes for review
* This targets `main` only, so it takes effect at the next
release-branch cut. The in-flight `release/v0.32` branch still carries
`v0.33.0-beta.0` / `python-v0.36.0-beta.0`; if we want the imminent
stable to be 0.37.0, this needs to be applied there too.
* Historical `python-v*` tags are left alone. The changelog builder
scans `^v`, which does not match them, so the first unified release's
notes will compute `fromTag` from the Rust/Node line only — a one-time
gap in the Python-side changelog.
* Pre-existing and not addressed here: `ci/update_lockfiles.sh --amend`
amends the commit that `bump-my-version` has already tagged, so the
lockfile update lands outside the tag on stable releases.
Fixes#3666
Bridges Lance's internal `metrics`-crate instrumentation (object store
request counts, bytes, latency, errors, and throttles) into
OpenTelemetry, in both the Python and Node bindings, with a shared
adapter in the Rust core. This is the LanceDB counterpart to
lance-format/lance#7537.
## Rust core (`rust/lancedb`)
Two new, **off-by-default** features:
- `metrics` — re-exports the [`metrics`](https://docs.rs/metrics) crate
as `lancedb::metrics` and turns on Lance's object-store instrumentation.
Install any `metrics`-compatible recorder to collect them.
- `metrics-otel` — adds `lancedb::metrics_otel`, a pull-based adapter
that installs a process-global recorder aggregating into lock-free
cumulative storage and exposes a snapshot/catalog API
(`register_metrics_recorder`, `metrics_catalog`, `snapshot_metrics`,
`MetricPoint`/`MetricValue`/`MetricKind`/`MetricDescription`). Both
bindings build on this.
## Python
`lancedb.otel.instrument_lancedb_metrics()` registers each metric as an
OpenTelemetry observable instrument on the given (or global)
`MeterProvider`. Available via the `otel` extra (`pip install
lancedb[otel]`), which pulls in only `opentelemetry-api` — the
application supplies and configures the SDK.
## Node
`instrumentLanceDbMetrics()` provides the equivalent wiring against
`@opentelemetry/api`. This is the only public entry point; the
underlying recorder/catalog/snapshot functions stay internal.
Because OpenTelemetry has no asynchronous histogram instrument,
histograms are exported Prometheus-style as `<name>_bucket` (with an
`le` attribute), `<name>_count`, and `<name>_sum`. Only `_sum` carries
the histogram's unit; `_bucket` and `_count` observe cumulative counts
and are unitless. The adapter is enabled by default in the Python and
Node builds, and off by default in the Rust crate.
## Notes
- Requires Lance ≥ `v9.0.0-beta.19`, which ships the object-store
metrics APIs (upstream lance-format/lance#7537, now merged). `main` is
already on beta.19, so this is a single feature commit with no
dependency bump.
- Tests: 8 Rust unit tests, 3 Python tests, 2 Node tests, all covering
the end-to-end object-store-metrics → OpenTelemetry path.

## Summary
Fixes the `NAPI_RS_FORCE_WASI=false` issue by upgrading `@napi-rs/cli`
from `3.5.1` to `3.7.0`.
Closes#3267
## Root Cause
In the `native.js` loader generated by `napi build`, the check was:
```js
if (!nativeBinding || process.env.NAPI_RS_FORCE_WASI) {
```
In JavaScript, any non-empty string is truthy, so
`NAPI_RS_FORCE_WASI=false` (a non-empty string) inadvertently triggered
the WASI fallback path. This caused an `ENOENT` error when
`lancedb.wasi.cjs` was not present.
## Fix
`@napi-rs/cli@3.7.0`
([napi-rs/napi-rs#3236](https://github.com/napi-rs/napi-rs/pull/3236))
introduced a tri-state check in the template that generates `native.js`:
**Before (generated by @napi-rs/cli@3.5.1):**
```js
if (!nativeBinding || process.env.NAPI_RS_FORCE_WASI) {
```
**After (generated by @napi-rs/cli@3.7.0):**
```js
const forceWasi =
process.env.NAPI_RS_FORCE_WASI === 'true' || process.env.NAPI_RS_FORCE_WASI === 'error'
if (!nativeBinding || forceWasi) {
```
Only the literal string `'true'` (or `'error'` for strict mode) now
activates the WASI path. All other values, including `'false'`, `'0'`,
or an unset variable, behave as if WASI is not forced.
## Changes
- `nodejs/package.json`: bump `@napi-rs/cli` from `3.5.1` to `3.7.0`
- `nodejs/package-lock.json` / `nodejs/pnpm-lock.yaml`: update lock
files to match
The fix is in the upstream napi-rs tool; the generated `native.js` is
not committed to this repository and is produced at build time by `napi
build`.
The 0.29 release happened on a branch because the main line had already
moved past the 6.0.0 stable lance release. As a result the version bump
commits ended up on the branch. This merges those commits back into
main.

## Summary
Switch the nodejs bindings and examples package from npm to pnpm 11 to
pick up its stronger supply-chain defaults:
- `minimumReleaseAge` defaults to 1 day, so newly-published (potentially
compromised) versions aren't resolved into installs for at least 24h.
- Install lifecycle scripts (`preinstall`/`install`/`postinstall`) are
no longer run for arbitrary transitive deps; only an explicit allowlist
may run them, and unapproved scripts cause install to fail
(`strictDepBuilds: true`).
- Audit uses GHSA IDs and `--fix=update` to add patched versions to
`minimumReleaseAgeExclude`.
This is the same class of protection that would have blunted the recent
TanStack/`@uipath`/etc. compromise discussed in the [Aikido
write-up](https://www.aikido.dev/blog/mini-shai-hulud-is-back-tanstack-compromised).
## Changes
- Replace `nodejs/package-lock.json` and
`nodejs/examples/package-lock.json` with `pnpm-lock.yaml`.
- Pin pnpm via `packageManager: pnpm@11.1.1` in both `package.json`s.
- Add `pnpm-workspace.yaml` with the four build-script packages we
actually need: `@biomejs/biome`, `onnxruntime-node`, `protobufjs`,
`sharp`. Everything else is blocked from running install scripts.
- Update package.json scripts (`npm run X` → `pnpm X`).
- Update workflows: `.github/workflows/nodejs.yml`,
`.github/workflows/npm-publish.yml`, and
`.github/workflows/codex-fix-ci.yml` — install pnpm via
`pnpm/action-setup@v4` and switch `setup-node` caches to
`pnpm-lock.yaml`.
- Refresh `nodejs/AGENTS.md`, `nodejs/CLAUDE.md`, and
`nodejs/CONTRIBUTING.md`.
`docs/package-lock.json` is **not** touched — out of scope for this PR.
## Test plan
- [ ] `Lint` job (lint Rust/TS + examples lint) passes on CI.
- [ ] `Linux (NodeJS 18/20)` build+test passes, including the examples
test step.
- [ ] `macos` build+test passes.
- [ ] `NPM Publish` workflow's PR dry-run completes (build matrix + test
matrix + dry `npm publish`).
- [ ] No new install-script approvals are required at install time.
## Follow-ups
- `update_package_lock_run_nodejs.yml` references a composite action
path that doesn't exist
(`./.github/workflows/update_package_lock_nodejs`); it was already
broken pre-PR. We may want to either delete this workflow or rewrite it
for pnpm in a follow-up.
- Consider migrating `docs/` to pnpm in a separate PR.

The `build:release` command already outputs the `*.node` files directly
to the `dist/` directory via the `--output-dir dist` flag.
Therefore, the `postbuild:release` script, which attempts to copy
`*.node` files from the `lancedb/` source directory, fails with a "no
such file or directory" error because the source files do not exist
there.
This commit removes the redundant `postbuild:release` script to resolve
the build failure.

## Summary
- Upgrades `@napi-rs/cli` from v2 to v3, `napi`/`napi-derive` Rust
crates to 3.x
- Fixes a bug
([napi-rs#1170](https://github.com/napi-rs/napi-rs/issues/1170)) where
the CLI failed to locate the built `.node` binary when a custom Cargo
target directory is set (via `config.toml`)
## Changes
**package.json / CLI**:
- `napi.name` → `napi.binaryName`, `napi.triples` → `napi.targets`
- Removed `--no-const-enum` flag and fixed output dir arg
- `napi universal` → `napi universalize`
**Rust API migration**:
- `#[napi::module_init]` → `#[napi_derive::module_init]`
- `napi::JsObject` → `Object`, `.get::<_, T>()` → `.get::<T>()`
- `ErrorStrategy` removed; `ThreadsafeFunction` now takes an explicit
`Return` type with `CalleeHandled = false` const generic
- `JsFunction` + `create_threadsafe_function` replaced by typed
`Function<Args, Return>` + `build_threadsafe_function().build()`
- `RerankerCallbacks` struct removed (`Function<'env,...>` can't be
stored in structs); `VectorQuery::rerank` now accepts the function
directly
- `ClassInstance::clone()` now returns `ClassInstance`, fixed with
explicit deref
- `Vec<u8>` in `#[napi(object)]` now maps to `Array<number>` in v3;
changed to `Buffer` to preserve the TypeScript `Buffer` type
**TypeScript**:
- `inner.rerank({ rerankHybrid: async (_, args) => ... })` →
`inner.rerank(async (args) => ...)`
- Header provider callback wrapped in `async` to match stricter typed
constructor signature
