Log Message:
py-django3: updated to 3.1.1

Django 3.1.1 fixes two security issues and several bugs in 3.1.

CVE-2020-24583: Incorrect permissions on intermediate-level directories on \ 
Python 3.7+

On Python 3.7+, FILE_UPLOAD_DIRECTORY_PERMISSIONS mode was not applied to \ 
intermediate-level directories created in the process of uploading files and to \ 
intermediate-level collected static directories when using the collectstatic \ 
management command.

You should review and manually fix permissions on existing intermediate-level \ 
directories.

CVE-2020-24584: Permission escalation in intermediate-level directories of the \ 
file system cache on Python 3.7+

On Python 3.7+, the intermediate-level directories of the file system cache had \ 
the system’s standard umask rather than 0o077 (no group or others \ 
permissions).

installation path.
Fixed detecting an async get_response callable in various builtin middlewares.
Fixed a QuerySet.order_by() crash on PostgreSQL when ordering and grouping by \ 
JSONField with a custom decoder.
