Breaking chances (for edge-case usages):
⚠️ getSetting() now longer return the locale when it's unchanged default, so you can distinguish between explicit 'en' which has Sunday as start of week vs. null which is English but with Monday as start of week. To get the previous behavior you can use:

$settings = array_merge(['locale' => 'en'], $date->getSettings());
