Components
Accordion Group
- `ionChange` is no longer emitted when the `value` of `ion-accordion-group` is modified externally. `ionChange` is only emitted from user committed changes, such as clicking or tapping the accordion header.
- Accordion Group no longer automatically adjusts the `value` property when passed an array and `multiple="false"`. Developers should update their apps to ensure they are using the API correctly.
Action Sheet
- Action Sheet is updated to align with the design specification.
**Design tokens**
| Token | Previous Value | New Value |
| ---------- | -------------- | --------- |
| `--height` | `100%` | `auto` |
- Button is updated to align with the design specification for iOS.
**Design tokens**
| Token | Previous Value | New Value |
| ---------------------------------- | -------------- | --------- |
| `$button-ios-letter-spacing` | `-0.03em` | `0` |
| `$button-ios-clear-letter-spacing` | `0` | Removed |
| `$button-ios-height` | `2.8em` | `3.1em` |
| `$button-ios-border-radius` | `10px` | `14px` |
| `$button-ios-large-height` | `2.8em` | `3.1em` |
| `$button-ios-large-border-radius` | `12px` | `16px` |
- Back Button is updated to align with the design specification for iOS.
**Design tokens**
| Token | Previous Value | New Value |
| ------------------- | -------------- | --------- |
| `--icon-margin-end` | `-5px` | `1px` |
| `--icon-font-size` | `1.85em` | `1.6em` |
- The card header has ben changed to a flex container with direction set to `column` (top to bottom). In `ios` mode the direction is set to `column-reverse` which results in the subtitle displaying on top of the title.
Checkbox
- `ionChange` is no longer emitted when the `checked` property of `ion-checkbox` is modified externally. `ionChange` is only emitted from user committed changes, such as clicking or tapping the checkbox.
- The `--background` and `--background-checked` CSS variables have been renamed to `--checkbox-background` and `--checkbox-background-checked` respectively.
Datetime
- `ionChange` is no longer emitted when the `value` property of `ion-datetime` is modified externally. `ionChange` is only emitted from user committed changes, such as clicking or tapping a date.
- Datetime no longer automatically adjusts the `value` property when passed an array and `multiple="false"`. Developers should update their apps to ensure they are using the API correctly.
- Datetime no longer incorrectly reports the time zone when `value` is updated. Datetime does not manage time zones, so any time zone information provided is ignored.
- Passing the empty string to the `value` property will now error as it is not a valid ISO-8601 value.
- The haptics when swiping the wheel picker are now enabled only on iOS.
- `ionChange` is no longer emitted when the `value` of `ion-input` is modified externally. `ionChange` is only emitted from user committed changes, such as typing in the input and the input losing focus, clicking the clear action within the input, or pressing the "Enter" key.
- If your application requires immediate feedback based on the user typing actively in the input, consider migrating your event listeners to using `ionInput` instead.
- The `debounce` property has been updated to control the timing in milliseconds to delay the event emission of the `ionInput` event after each keystroke. Previously it would delay the event emission of `ionChange`.
- The `debounce` property's default value has changed from `0` to `undefined`. If `debounce` is undefined, the `ionInput` event will fire immediately.
- The `detail` payload for the `ionInput` event now contains an object with the current `value` as well as the native event that triggered `ionInput`.
**Design tokens**
| Token | Previous Value | New Value |
| ----------------------- | -------------- | --------- |
| `--placeholder-opacity` | `0.5` | `0.6` |
Item
**Design tokens**
iOS:
| Token | Previous Value | New Value |
| --------------------- | -------------- | --------- |
| `$item-ios-font-size` | `17px` | `16px` |
| `--inner-padding-end` | `10px` | `16px` |
| `--padding-start` | `20px` | `16px` |
Modal
- The `swipeToClose` property has been removed in favor of `canDismiss`.
- The `canDismiss` property now defaults to `true` and can no longer be set to `undefined`.
Overlays
Ionic now listens on the `keydown` event instead of the `keyup` event when determining when to dismiss overlays via the "Escape" key. Any applications that were listening on `keyup` to suppress this behavior should listen on `keydown` instead.
Picker
- The `refresh` key has been removed from the `PickerColumn` interface. Developers should use the `columns` property to refresh the `ion-picker` view.
Radio Group
- `ionChange` is no longer emitted when the `value` of `ion-radio-group` is modified externally. `ionChange` is only emitted from user committed changes, such as clicking or tapping an `ion-radio` in the group.
Range
- Range is updated to align with the design specification for supported modes.
**Design tokens**
iOS:
| Token | Previous Value | New Value |
| --------------------------------- | ----------------------------------------------------------------------------------------- | --------------------------------------------------------------------- |
| `--bar-border-radius` | `0px` | `$range-ios-bar-border-radius` (`2px` default) |
| `--knob-size` | `28px` | `$range-ios-knob-width` (`26px` default) |
| `$range-ios-bar-height` | `2px` | `4px` |
| `$range-ios-bar-background-color` | `rgba(var(--ion-text-color-rgb, 0, 0, 0), .1)` | `var(--ion-color-step-900, #e6e6e6)` |
| `$range-ios-knob-box-shadow` | `0 3px 1px rgba(0, 0, 0, .1), 0 4px 8px rgba(0, 0, 0, .13), 0 0 0 1px rgba(0, 0, 0, .02)` | `0px 0.5px 4px rgba(0, 0, 0, 0.12), 0px 6px 13px rgba(0, 0, 0, 0.12)` |
| `$range-ios-knob-width` | `28px` | `26px` |
- `ionChange` is no longer emitted when the `value` of `ion-range` is modified externally. `ionChange` is only emitted from user committed changes, such as dragging and releasing the range knob or selecting a new value with the keyboard arrows.
- If your application requires immediate feedback based on the user actively dragging the range knob, consider migrating your event listeners to using `ionInput` instead.
- The `debounce` property's value value has changed from `0` to `undefined`. If `debounce` is undefined, the `ionInput` event will fire immediately.
- Range no longer clamps assigned values within bounds. Developers will need to validate the value they are assigning to `ion-range` is within the `min` and `max` bounds when programmatically assigning a value.
- The `name` property defaults to `ion-r-${rangeIds++}` where `rangeIds` is a number that is incremented for every instance of `ion-range`.
Searchbar
- `ionChange` is no longer emitted when the `value` of `ion-searchbar` is modified externally. `ionChange` is only emitted from user committed changes, such as typing in the searchbar and the searchbar losing focus or pressing the "Enter" key.
- If your application requires immediate feedback based on the user typing actively in the searchbar, consider migrating your event listeners to using `ionInput` instead.
- The `debounce` property has been updated to control the timing in milliseconds to delay the event emission of the `ionInput` event after each keystroke. Previously it would delay the event emission of `ionChange`.
- The `debounce` property's default value has changed from 250 to `undefined`. If `debounce` is undefined, the `ionInput` event will fire immediately.
- The `detail` payload for the `ionInput` event now contains an object with the current `value` as well as the native event that triggered `ionInput`.
**Design tokens**
| Token | Previous Value | New Value |
| ----------------------- | -------------- | --------- |
| `--placeholder-opacity` | `0.5` | `0.6` |
Segment
- `ionChange` is no longer emitted when the `value` of `ion-segment` is modified externally. `ionChange` is only emitted from user committed changes, such as clicking a segment button or dragging to activate a segment button.
- The type signature of `value` supports `string | undefined`. Previously the type signature was `string | null | undefined`.
- Developers needing to clear the checked segment item should assign a value of `''` instead of `null`.
Select
- `ionChange` is no longer emitted when the `value` of `ion-select` is modified externally. `ionChange` is only emitted from user committed changes, such as confirming a selected option in the select's overlay.
- The `icon` CSS Shadow Part now targets an `ion-icon` component.
**Design tokens**
| Token | Previous Value | New Value |
| ----------------------- | -------------- | --------- |
| `--placeholder-opacity` | `0.33` | `0.6` |
Slides
`ion-slides`, `ion-slide`, and the `IonicSwiper` plugin have been removed from Ionic.
Developers using these components will need to migrate to using Swiper.js directly, optionally using the `IonicSlides` plugin. Guides for migration and usage are linked below:
- [Angular](https://ionicframework.com/docs/angular/slides)
- [React](https://ionicframework.com/docs/react/slides)
- [Vue](https://ionicframework.com/docs/vue/slides)
Textarea
- `ionChange` is no longer emitted when the `value` of `ion-textarea` is modified externally. `ionChange` is only emitted from user committed changes, such as typing in the textarea and the textarea losing focus.
- If your application requires immediate feedback based on the user typing actively in the textarea, consider migrating your event listeners to using `ionInput` instead.
- The `debounce` property has been updated to control the timing in milliseconds to delay the event emission of the `ionInput` event after each keystroke. Previously it would delay the event emission of `ionChange`.
- The `debounce` property's default value has changed from `0` to `undefined`. If `debounce` is undefined, the `ionInput` event will fire immediately.
- `ionInput` dispatches an event detail of `null` when the textarea is cleared as a result of `clear-on-edit="true"`.
- The `detail` payload for the `ionInput` event now contains an object with the current `value` as well as the native event that triggered `ionInput`.
**Design tokens**
| Token | Previous Value | New Value |
| ----------------------- | -------------- | --------- |
| `--placeholder-opacity` | `0.5` | `0.6` |
Toggle
- `ionChange` is no longer emitted when the `checked` property of `ion-toggle` is modified externally. `ionChange` is only emitted from user committed changes, such as clicking the toggle to set it on or off.
- The `--background` and `--background-checked` variables have been renamed to `--track-background` and `--track-background-checked`, respectively.
`ion-virtual-scroll` has been removed from Ionic.
Developers using the component will need to migrate to a virtual scroll solution provided by their framework:
- [Angular](https://ionicframework.com/docs/angular/virtual-scroll)
- [React](https://ionicframework.com/docs/react/virtual-scroll)
- [Vue](https://ionicframework.com/docs/vue/virtual-scroll)
Any references to the virtual scroll types from `@ionic/core` have been removed. Please remove or replace these types: `Cell`, `VirtualNode`, `CellType`, `NodeChange`, `HeaderFn`, `ItemHeightFn`, `FooterHeightFn`, `ItemRenderFn` and `DomRenderFn`.
Config
- `innerHTMLTemplatesEnabled` defaults to `false`. Developers who wish to use the `innerHTML` functionality inside of `ion-alert`, `ion-infinite-scroll-content`, `ion-loading`, `ion-refresher-content`, and `ion-toast` must set this config to `true` and properly sanitize their content.
Types
Overlay Attribute Interfaces
`ActionSheetAttributes`, `AlertAttributes`, `AlertTextareaAttributes`, `AlertInputAttributes`, `LoadingAttributes`, `ModalAttributes`, `PickerAttributes`, `PopoverAttributes`, and `ToastAttributes` have been removed. Developers should use `{ [key: string]: any }` instead.
JavaScript Frameworks
Angular
- Angular v14 is now required to use `@ionic/angular` and `@ionic/angular-server`. Upgrade your project to Angular v14 by following the [Angular v14 update guide](https://update.angular.io/?l=3&v=13.0-14.0).
- `null` values on form components will no longer be converted to the empty string (`''`) or `false`. This impacts `ion-checkbox`, `ion-datetime`, `ion-input`, `ion-radio`, `ion-radio-group`, `ion-range`, `ion-searchbar`, `ion-segment`, `ion-select`, `ion-textarea`, and `ion-toggle`.
- The dev-preview `environmentInjector` property has been removed from `ion-tabs` and `ion-router-outlet`. Standalone component routing is now available without additional custom configuration. Remove the `environmentInjector` property from your `ion-tabs` and `ion-router-outlet` components.
React
`@ionic/react` and `@ionic/react-router` no longer ship a CommonJS entry point. Instead, only an ES Module entry point is provided for improved compatibility with Vite.
Vue
`@ionic/vue` and `@ionic/vue-router` no longer ship a CommonJS entry point. Instead, only an ES Module entry point is provided for improved compatibility with Vite.
CSS Utilities
`hidden` attribute
The `[hidden]` attribute has been removed from Ionic's global stylesheet. The `[hidden]` attribute can continue to be used, but developers will get the [native `hidden` implementation](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/hidden) instead. The main difference is that the native implementation is easier to override using `display` than Ionic's implementation.
Developers can add the following CSS to their global stylesheet if they need the old behavior:
```css
[hidden] {
display: none !important;
}
```
