Ionic 6.3 introduces several enhancements and new features aimed at improving user experience and developer capabilities. Notable updates include improved multiple date selection with enhanced header text and added support for the ion-datetime-button, as well as experimental support for Angular standalone component routing, which allows developers to assign the environmentInjector property to ion-router-outlet or ion-tabs components. Accessibility improvements have been made to the ion-range component, ensuring clearer indications when the range knob is hovered, focused, or active. Additionally, the ion-alert component now supports promises for button handlers, enabling asynchronous operations before dismissal, and the ion-button can be configured to submit a form from outside the form itself, thanks to community contributions. These updates reflect Ionic's commitment to integrating community feedback and enhancing the framework's versatility.
