# Django 3.1.11 release notes

*May 13, 2021*

Django 3.1.11 fixes a regression in 3.1.9.

## Bugfixes

- Fixed a regression in Django 3.1.9 where saving `FileField` would raise a
  `SuspiciousFileOperation` even when a custom
  [`upload_to`](/ja/4.2/ref/models/fields/#django.db.models.FileField.upload_to) returns a valid file path
  ([#32718](https://code.djangoproject.com/ticket/32718)).
