django-qr-code was used for one thing: the QR code in the OTP e-mail,
as an inline SVG and a PNG. It brought pydantic, pydantic-core,
annotated-types and typing-inspection (about 10 MB) and, from 5.0 on,
Pillow. segno, which it used underneath, now draws both images with the
same options (error correction M, 4-module border, 1.8 mm SVG modules,
12 px PNG modules); the SVG, the PNG and the alt text are byte for byte
what django-qr-code 4.2 produced. account.html loaded the tag library
without using it.
- user_block, user_unblock and admin_email_otp changed state on GET, so an
<img> tag could lock a user out or trigger OTP emails through an
admin's session. They now require POST; the buttons are CSRF forms.
- The console token cookie is set with httponly, SameSite=Lax and, on
HTTPS, secure. Only novncd reads it; the page gets the token directly.
