Django 3.0.1 release notes

漏洞修复

• Fixed a regression in Django 3.0 by restoring the ability to use Django inside Jupyter and other environments that force an async context, by adding an option to disable mechanism with environment variable ().
• Reallowed, following a regression in Django 3.0, Window expressions to be used in conditions outside of queryset filters, e.g. in conditions (#31060).
