Greptile Summary

Bumps the SDK version from 19.1.0 to 19.2.0 across all relevant metadata files following the concurrent chunk upload update.

• appwrite/client.py: version string updated in both the user-agent header and the x-sdk-version header.
• pyproject.toml and setup.py: package version and download_url updated consistently to 19.2.0.

Confidence Score: 5/5

Pure version metadata bump touching only version strings — no logic, no behavior change.

All three changed files are simple string replacements updating the version from 19.1.0 to 19.2.0 consistently. The user-agent header, x-sdk-version header, pyproject.toml, setup.py version field, and download_url all agree on the new version.

No files require special attention.
