lowercasing all passwords to match the format expected by the validator.
Prevented repetitive calls to geos_version_tuple() in the WKBWriter class in an \ 
attempt to fix a random crash involving LooseVersion.
Fixed keep-alive support in runserver after it was disabled to fix another issue \ 
in Django 2.0.
Fixed admin view-only change form crash when using ModelAdmin.prepopulated_fields.
