chore: update lance dependency to v4.0.0-beta.6

fix(ci): only run npm publish on release tags (#3093 )
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.

lancedb automation	1ade8846fd	chore: update lance dependency to v4.0.0-beta.6	2026-03-03 18:54:14 +00:00
Xuanwo	52ce2c995c	fix(ci): only run npm publish on release tags (#3093 ) 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.	2026-03-04 01:35:10 +08:00
Sean Mackrory	e71a00998c	ci: add regression test for fastSearch in FTS queries in TypeScript (#3090 ) We recently added support for this for the Python bindings, and wanted to confirm this already worked as expected in the TS bindings.	2026-03-03 07:09:09 -08:00
Sean Mackrory	39a2ac0a1c	feat: add parity between fast_search keyword argument between vector and FTS searches (#3091 ) We don't necessarily need to do this, but one user was confused having used `fast_search=True` as a keyword argument for vector searches, but being unable to do so for FTS, even after the most recent changes. I think this is the only discrepancy in where that is possible.	2026-03-03 05:21:36 -08:00
