# Django 3.1.5 release notes

January 4, 2021

Django 3.1.5 fixes several bugs in 3.1.4.

## Perbaikan kesalahan

- Fixed `__isnull=True` lookup on key transforms for `JSONField` with Oracle and SQLite (#32252).
- Fixed a bug in Django 3.1 that caused a crash when processing middlewares in an async context with a middleware that raises a `MiddlewareNotUsed` exception (#32299).
- Fixed a regression in Django 3.1 that caused the incorrect prefixing of `STATIC_URL` and `MEDIA_URL` settings, by the server-provided value of `SCRIPT_NAME` (or `/` if not set), when set to a URL specifying the protocol but without a top-level domain, e.g. `http://myhost/` (#32304).
