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 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.
