v9.0.0

Ionic Theme MD3 v9.0.0

This release aligns the theme's major version with Ionic 9 while continuing to support Ionic 8.

If you are upgrading from a version released last month or earlier, v9 also includes the UI features and fixes introduced on the way through v2.x.

Compatibility

• @ionic/core >=8.8.0 <10
• Ionic 8 and Ionic 9 demos and visual regression coverage

npm install @rdlabo/ionic-theme-md3@^9

Breaking change for users upgrading from v1.x or earlier

Rename the Inset List section-header class:

- <ion-item-group class="header-item-group">
+ <ion-item-group class="item-group-header">

The old class has been removed. If you already use v2.x, no additional application-side markup change is required for v9.0.0.

See the migration guide for details.

Included since the earlier releases

• Two-line ion-item layouts with Supporting text
• Natural helperText and errorText layouts for Inputs and Textareas
• Shared markup and documented integration with @rdlabo/ionic-theme-ios26
• Ionic 8 and Ionic 9 visual regression tests in Light and Dark modes
• Refined dividers, icon-only Buttons, navigation, and component presentation
• Companion ESLint rule guidance for consistent Inset List structure
