## Migration Guide ##

### 24.x Breaking Changes ###

**jQuery namespaced events are removed.** Events are now plain native DOM custom events. If your application listens to or unbinds events using jQuery-style namespacing, you must update those calls.

Before:

```js
$(form).on('form:validate:before.ClientSideValidations', handler)
$(input).off('.ClientSideValidations')
```

After:

```js
form.addEventListener('form:validate:before', handler)
// store and pass the handler reference to removeEventListener when unbinding
```

The full list of native events dispatched by ClientSideValidations: `form:validate:before`, `form:validate:after`, `form:validate:pass`, `form:validate:fail`, `element:validate:before`, `element:validate:after`, `element:validate:pass`, `element:validate:fail`.

## Initializer ##

The initializer includes a commented out `ActionView::Base.field_error_proc`.
