Migrating from yii2-bootstrap4

General

  • The namespace is yii\bootstrap5 instead of yii\bootstrap4
  • The php compatibility is limited to >=7.0
  • The close buttons of widgets like yii\bootstrap5\Alert or yii\bootstrap5 now gets rendered via CSS and does not have any content anymore. So be sure to remove btn-close class and set appropriate styles yourself if you override it.
