Standard GitHub-hosted runners are free on public repos, so all Actions
spend here is on the `*-8x-*` / `4x` larger runners. Measured over 30
days at current (post-Jan-2026) larger-runner rates, that is ~$1,400/mo,
and `npm-publish` is ~70% of it.
## Changes
**Fat LTO was forcing builds onto large runners.** `[profile.release]`
in `.cargo/config.toml` sets `lto = "fat"` with `codegen-units = 1`,
which is single-threaded and the peak-memory step. The macOS
`npm-publish` build was 111 of its 113 minutes in one `napi build` step,
making it the critical path of the whole publish pipeline. The ThinLTO
override already applied to Windows now covers macOS too, and both
Windows builds move from `windows-2025-8x-x64` to the free standard
`windows-2025`.
**The npm-publish cargo cache never existed.** There are zero caches
with its key prefix. The key was static, so `actions/cache` (which only
writes on a miss) could never refresh it, and a multi-GB release
`target/` per target could never fit the repo's 10 GB budget anyway. Now
caches only the crate registry, keyed on `Cargo.lock`. The docker builds
also mounted `.cargo/registry/*` while the cache saved `.cargo-cache`,
so containers re-downloaded the registry every run.
**Cache eviction thrash.** Repo cache usage is 10.4 GB against GitHub's
10 GB cap, so every PR run evicted main's warm entries. `rust.yml` and
`nodejs.yml` now restore everywhere but only save from `main`.
**npm-publish moves to nightly + tags** instead of every push to main
(~90/month). The cross-compiled targets do need watching, so
`report-failure` now fires on scheduled runs, and dedupes onto an
existing open issue rather than filing one per night.
**rust.yml aarch64-pc-windows-msvc** cross-compiled its tests and then
skipped them, paying full codegen and link cost for a compile check.
`windows-11-arm` is now GA and free on public repos, so it builds and
tests natively. Its test step also passes `--target` — without it cargo
used `target/ci/` rather than `target/<triple>/ci/` and rebuilt the
entire dependency graph a second time.
**pypi-publish.yml had no concurrency group**, so force-pushes left a
~74 minute Windows job running.
## What is cost vs. wall-clock
| Change | Cost | Wall-clock |
|---|---|---|
| Windows npm-publish → free runners | **−$570/mo** | slower per job
(8→4 cores) |
| npm-publish nightly | **−$125/mo** | — |
| pypi-publish concurrency | small | — |
| macOS ThinLTO | $0 (already free) | **−~50 min** per release |
| rust aarch64 Windows native | $0 (already free) | **−~25 min** |
| rust `--target` on test step | $0 | large, avoids a second full build
|
| rust-cache `save-if` | small | faster via real cache hits |
## Risks
- The two Windows builds now have 4 cores instead of 8 and ~14 GB of
free disk. If they fail, it is most likely disk rather than memory;
fallback is `windows-2025-4x-x64`, which still halves that line.
- `windows-11-arm` has a thinner toolset (choco/vcpkg/protoc under
emulation) and this enables a test step that has never run, so it may
surface real aarch64 failures. That is the point, but it is the change
most likely to need iteration.
- ThinLTO applies to published macOS and Windows binaries, typically
within a few percent of fat LTO. Linux release builds are untouched.
## Follow-ups
- `python.yml` `pydantic1x` (37 min) and `Doctest` (33 min) each rebuild
the extension from source via `pip install -e .` with no Rust cache;
they should consume the wheel the `linux` job already builds. Worth
~$235/mo and ~70 min of compute per run. Separate PR.
- The three `ubuntu-2404-8x-x64` npm-publish builds (~$420/mo at the old
cadence) are the remaining large-runner spend;
`aarch64-unknown-linux-gnu` could run natively on free
`ubuntu-24.04-arm`. Worth doing after this lands so the ThinLTO change
can be validated first.
- The wheel composite actions declare `python-minor-version` as required
but never use it, and every caller omits it (actionlint warns).

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
The `build - aarch64-pc-windows-msvc` node build job (and, marginally,
the x86_64 one) had started hitting `rustc-LLVM ERROR: out of memory`
while linking the `lancedb-nodejs` cdylib — most recently surfaced by
#3526, which adds the goosefs backend (and its tonic/prost gRPC subtree)
to the default node binary.
The peak-memory step is the fat-LTO codegen (`lto=fat`,
`codegen-units=1` from `.cargo/config.toml`), which merges the whole
crate graph into a single LLVM module and runs single-threaded. It
therefore neither parallelizes across cores nor fits in the 16 GB of the
standard `windows-latest` runner as the dependency graph grows.
This PR:
- Moves both `*-pc-windows-msvc` node build jobs to
`windows-2025-8x-x64` (more memory + cores).
- Overrides the release profile to ThinLTO for just these jobs, via
`CARGO_PROFILE_RELEASE_LTO=thin` /
`CARGO_PROFILE_RELEASE_CODEGEN_UNITS=16` in `pre_build`. ThinLTO
parallelizes the cross-module optimization across the runner's cores and
keeps peak memory well under the limit. Scoped so Python wheels and Rust
release builds keep fat LTO.
The larger runner alone would clear the OOM but waste the added cores on
the single-threaded fat-LTO tail; ThinLTO is what makes the extra cores
actually reduce wall-clock and gives durable memory headroom for future
dependency growth.
Tradeoff: ThinLTO can leave a small runtime-perf gap vs fat LTO for the
node native binary, but it recovers most of it and is a common release
configuration.

## 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.

This PR fixes the npm publish dry-run failure for prerelease versions
without changing the existing workflow trigger behavior. The publish
step now detects prerelease versions from `nodejs/package.json` and
always appends `--tag preview` when needed.
Context:
- On `main` pushes, the workflow still runs `npm publish --dry-run` by
design.
- Recent failures were caused by prerelease versions (for example
`0.27.0-beta.3`) running without `--tag`, which npm rejects.
- The previous `refs/tags/v...-beta...` check did not apply on branch
pushes, so dry-run could fail even though release tags worked.
## 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

## Summary
The `report-failure` jobs in npm, cargo, and pypi publish workflows
checked for
`release` or `workflow_dispatch` events, but these workflows are
triggered by tag
pushes where `github.event_name` is `push`. The condition was never
true, so failure
notifications were silently skipped.
- Use `startsWith(github.ref, 'refs/tags/...')` to match actual tag
triggers
- Add `failure()` to only notify on actual failures
This matches the pattern already used by `java-publish.yml`.

We have very low download stats for mac x86, and also latest github
runners for mac are all arm, so it makes sense at this point to
deprecate x86 support in general.
## Summary
- Created custom GitHub Action that creates issues when workflow jobs
fail
- Added report-failure jobs to cargo-publish.yml, java-publish.yml,
npm-publish.yml, and pypi-publish.yml
- Issues are created automatically with workflow name, failed job names,
and run URL
## Test plan
- Workflows will only create issues on actual release or
workflow_dispatch events
- Can be tested by triggering workflow_dispatch on a publish workflow

across Linux platforms.
- Updated environment settings for more accurate compiler integration.
- Activated previously inactive build configurations to support advanced
feature support.
- Added support for the x86_64 architecture on Linux systems utilizing

<!-- end of auto-generated comment: release notes by coderabbit.ai -->
This PR fixes build issues associated with `aws-lc-rs`, while
simplifying the build process. Previously, we used custom scripts for
the musl and Windows ARM builds. These were complicated and prone to
breaking. This PR switches to a setup that mirrors
https://github.com/napi-rs/package-template/blob/main/.github/workflows/CI.yml.
* linux glibc and musl builds now use the Docker images provided by the
napi project
* Windows ARM build now just cross compiles from Windows x64, which
turns out to work quite well.
`object_store` already hard codes `rustls` as the TLS implementation, so
we have been shipping a mix of `rustls` and `openssl`. For simplicity of
builds, we should consolidate to one, and that has to be `rustls`.
vectordb is deprecated, and these platforms are particularly difficult
to maintain. Removing now to prevent further headaches.
We will keep these platforms supported on `@lancedb/lancedb`.
We upgraded the toolchain in #1960, but didn't realize we hardcoded it
in `npm-publish.yml`. I found if I just removed the hard-coded
toolchain, it selects the correct one.
This didn't fully fix Windows Arm, so I created a follow-up issue here:
https://github.com/lancedb/lancedb/issues/1975
fixes that all `neon pack-build` packs are named
`vectordb-linux-x64-musl-*.tgz` even when cross-compiling
adds 2nd param:
`TARGET_TRIPLE=${2:-x86_64-unknown-linux-gnu}`
`npm run pack-build -- -t $TARGET_TRIPLE`
* Labelled jobs `vectordb` and `lancedb` so it's clear which package
they are for
* Fix permission issue in aarch64 Linux `vectordb` build that has been
blocking release for two months.
* Added Slack notifications for failure of these publish jobs.
This PR changes the release process. Some parts are more complex, and
other parts I've simplified.
## Simplifications
* Combined `Create Release Commit` and `Create Python Release Commit`
into a single workflow. By default, it does a release of all packages,
but you can still choose to make just a Python or just Node/Rust release
through the arguments. This will make it rarer that we create a Node
release but forget about Python or vice-versa.
* Releases are automatically generated once a tag is pushed. This
eliminates the manual step of creating the release.
* Release notes are automatically generated and changes are categorized
based on the PR labels.
* Removed the use of `LANCEDB_RELEASE_TOKEN` in favor of just using
`GITHUB_TOKEN` where it wasn't necessary. In the one place it is
necessary, I left a comment as to why it is.
* Reused the version in `python/Cargo.toml` so we don't have two
different versions in Python LanceDB.
## New changes
* We now can create `preview` / `beta` releases. By default `Create
Release Commit` will create a preview release, but you can select a
"stable" release type and it will create a full stable release.
* For Python, pre-releases go to fury.io instead of PyPI
* `bump2version` was deprecated, so upgraded to `bump-my-version`. This
also seems to better support semantic versioning with pre-releases.
* `ci` changes will now be shown in the changelog, allowing changes like
this to be visible to users. `chore` is still hidden.
## Versioning
**NOTE**: unlike how it is in lance repo right now, the version in main
is the last one released, including beta versions.

When we turned on fat LTO builds, we made the release build job **much**
more compute and memory intensive. The ARM runners have particularly low
memory per core, which makes them susceptible to OOM errors. To avoid
issues, I have enabled memory swap on ARM and bumped the side of the
runner.
