Summary

Bump the canonical Metaflow package version from 2.19.38 to 2.19.39 for the next patch release.

Issue

N/A — routine patch release.

Reproduction

Not applicable; this PR changes release metadata only.

Root Cause

Not applicable.

Why This Fix Is Correct

2.19.38 is the latest published release, and this updates only metaflow/version.py to the next patch version.

Failure Modes Considered

1. Incorrect version sequence: confirmed the latest published GitHub release and repository tag are both 2.19.38.
2. Unrelated changes: confirmed the PR contains a one-line version change only.

Tests

• Unit tests added/updated
• Reproduction script provided
• CI passes
• If tests are impractical: python setup.py --version reports 2.19.39, git diff --check passes, and all configured pre-commit hooks pass for the changed file.

Non-Goals

No runtime behavior, dependencies, or release automation are changed.

Greptile Summary

This PR advances the canonical Metaflow Python package version from 2.19.38 to 2.19.39.

• Updates the single version declaration in metaflow/version.py.
• Preserves the established patch-release version format and shared package-version source.

Confidence Score: 5/5

The PR appears safe to merge because the patch bump updates the shared canonical version source without introducing inconsistent metadata.

The package, runtime version export, and stubs packaging derive their versions from the changed declaration, and the new value follows the existing release convention.
