What's New

This page collects relevant information about Apache Arrow JS releases.

caution

Apache Arrow JS follows cross-language versioning from the Apache Arrow project. A major version bump does not always imply JavaScript API breakage.

For JS users, the primary risk is dependency alignment: multiple packages in the same app may resolve different apache-arrow majors and cause bundling/runtime incompatibilities.

v21.0​

  • Apache Arrow 21.0.0
  • Apache Arrow JS did not publish extensive JavaScript-only notes for this release stream; treat tableFromIPC/tableToIPC, message readers, and stream readers as the major integration touch points.
