- Update to 3.1.0:
* Don't return the default locale twice.
* Fix tests breaking against babel 12.2, which changed localized times to
use non-breaking-spaces.
* Relax version requirements for dependencies.
* Dropped support for end-of-life Python 3.5 and 3.6, added tests for 3.10
and 3.11.
* Jinja version 3 or greater is now required.
* Removed Babel._date_formats, use the public Babel.date_formats instead.
* list_translations() always returns the default locale, even if it does
not exist.
* Babel.locale_selector and Babel.timezone_selector no longer exist.
* Most configuration options can be passed directly through init_app().
