DecimalField must itself validate() values, such as NaN, which cannot be
passed to validators, such as MaxValueValidator, during the
run_validators() phase.

Regression introduced in 513948735b799239f3ef8c89397592445e1a0cd5
by marking the raw SQL column reference feature for deprecation in
Django 4.0 while lifting the column format validation.
In retrospective the validation should have been kept around and the
user should have been pointed at using RawSQL expressions during the
deprecation period.
The main branch is not affected because the raw SQL column reference
support has been removed in 06eec3197009b88e3a633128bbcbd76eea0b46ff
per the 4.0 deprecation life cycle.
Thanks Joel Saunders for the report.

URLValidator() uses a regular expressions and it was affected on all
Python versions.

- Validate filename returned by FileField.upload_to() not a filename
passed to the FileField.generate_filename() (upload_to() may
completely ignored passed filename).
- Allow relative paths (without dot segments) in the generated filename.

In Python 3.9.5+ urllib.parse() automatically removes ASCII newlines
and tabs from URLs [1, 2]. Unfortunately it created an issue in
the URLValidator. URLValidator uses urllib.urlsplit() and
urllib.urlunsplit() for creating a URL variant with Punycode which no
longer contains newlines and tabs in Python 3.9.5+. As a consequence,
the regular expression matched the URL (without unsafe characters) and
the source value (with unsafe characters) was considered valid.

Subquery deconstruction support required implementing complex and
expensive equality rules for sql.Query objects for little benefit as
the latter cannot themselves be made deconstructible to their reference
to model classes.
Making Expression @deconstructible and not BaseExpression allows
interested parties to conform to the "expression" API even if they are
not deconstructible as it's only a requirement for expressions allowed
in Model fields and meta options (e.g. constraints, indexes).
