Always converted

This was required to accommodate growth in Django’s own test suite (#23969).
Fixed
timesince
filter translations in Korean (#23989).Fixed the SQLite
SchemaEditor
to properly add defaults in the absence of a user specifieddefault

Added
datetime.time
support to migrations questioner (#23998).Fixed admindocs crash on apps installed as eggs (#23525).
Changed migrations autodetector to generate an
AlterModelOptions
operation instead ofDeleteModel

fromFalse
toTrue
and vice versa (#24037).Enabled the
sqlsequencereset
command on apps with migrations (#24054).Added tablespace SQL to apps with migrations (#24051).
Corrected
contrib.sites
default site creation in a multiple database setup (#24000).Restored support for objects that aren’t
str
orbytes
indjango.utils.safestring.mark_for_escaping()
on Python 3.Supported strings escaped by third-party libraries with the
__html__
convention in the template engine (#23831).Prevented extraneous
DROP DEFAULT
SQL in migrations (#23581).Restored the ability to use more than five levels of subqueries (#23758).

that is initialized with a dictionary (#24008).Prevented a crash on apps without migrations when running
