This upgrade of Tornado from version 6.2 to 6.5.7 includes two main changes that require attention: dropped support for older Python versions and stricter HTTP header parsing.

Key Changes:

  • Python Version Support:

    • Tornado 6.3 dropped support for Python 3.7, making Python 3.8 the minimum required version.
    • Tornado 6.5 further increased the requirement to Python 3.9.

  • Stricter HTTP Parsing:

    • Across several patch releases (6.3.3, 6.4.1, 6.5.x), parsing for HTTP headers like Content-Length, Transfer-Encoding, and multipart form data has become more strict to align with RFCs and address security vulnerabilities.
    • Requests with malformed headers or method names that were previously tolerated may now result in errors (e.g., HTTP 400).

Recommendation:

  • Verify that your production environment is running Python 3.9 or newer.
  • Review integration tests to ensure that clients interacting with your Tornado application are sending compliant HTTP requests, as the server will be less tolerant of malformed headers.
