* Migration::upsert() returns void * Unneeded `@property` tags * Add missing `null` param/return types * Null types for db\Query + db\ActiveQuery * Fixed testSelect * Null types for Validator * Several more null types * One more * Make AccessRule::$allow always a boolean It doesn't have any special null handling, so it's safe to default to false * Validator::$skipOnEmpty is always a boolean * Catch all throwable from Widget::widget() * Don't limit $previous args to \Exception The actual \Exception allows $previous to be any throwable in PHP 7+ * Add Throwable catch block to Instance::get() * Throwable cleanup Comment changes only. - Document \Throwable instead of \Exception wherever appropriate - Removed redundant exception/error classes when \Throwable is referenced * Yii::setlogger() accepts null * ArrayHelper::removeValue() can remove any type of value * Change default $allow value to false
