+=============
 
-## Pretty URLs
+## EasyAdmin 5.0.14
+
+The HTML markup of the boolean switch has changed. Before, the element wrapping
+the switch applied the `.form-switch` CSS class and the checkbox used the
+`.form-check-input` class. Now, the switch is rendered with the new
+`<twig:ea:Switch>` component: the wrapping element uses the `.ea-switch` class and
+the checkbox uses the `.ea-switch-input` class. This affects both the switch shown
+in the `index` page and the one displayed in the `edit`/`new` forms. Update any
+custom CSS or JavaScript that targeted the old selectors.

+Colored Switches
+~~~~~~~~~~~~~~~~
+
+By default the switch uses a neutral color when it's turned on. If you want to
+highlight its meaning, use one of the following methods to color the "on" state
+with the same colors as the ``success``, ``warning`` and ``danger`` buttons.
+These methods also enable the switch rendering, so you don't need to call
+``renderAsSwitch()`` too::
+
+    yield BooleanField::new('...')->renderAsSuccessSwitch();  // green when on
+    yield BooleanField::new('...')->renderAsWarningSwitch();  // amber when on
+    yield BooleanField::new('...')->renderAsDangerSwitch();   // red when on
+
+The color is applied everywhere the field is rendered as a switch (the ``index``
+toggle and the ``edit``/``new`` forms). The "off" state always uses the neutral color.
