Flask v1.0.3 Release Notes

Release Date: 2019-07-09 // almost 5 years ago

  • 🚀 Released 2019-05-17

    • :func:send_file encodes filenames as ASCII instead of Latin-1 (ISO-8859-1). This fixes compatibility with Gunicorn, which is stricter about header encodings than PEP 3333. :issue:2766
    • Allow custom CLIs using FlaskGroup to set the debug flag without it always being overwritten based on environment variables. :pr:2765
    • flask --version outputs Werkzeug's version and simplifies the Python version. :pr:2825
    • :func:send_file handles an attachment_filename that is a native Python 2 string (bytes) with UTF-8 coded bytes. :issue:2933
    • A catch-all error handler registered for HTTPException will not handle RoutingException, which is used internally during routing. This fixes the unexpected behavior that had been introduced in 1.0. :pr:2986
    • ✅ Passing the json argument to app.test_client does not push/pop an extra app context. :issue:2900
