Removed Tabs preloadTabs ability. This is no longer needed with the Ahead of Time (AoT) compiler.
Icons in buttons require an attribute on the parent button in order to style them.
Platform and mode CSS classes have been moved from the
element to the element.
select: Select’s alertOptions input has been renamed to selectOptions. See moredetails here.
colors: Colors should be passed in the color input on components, not added
individually as an attribute on the component. See more details here.
buttons: <button> becomes <button ion-button>. See more details here and here.
Head link tags for CSS files are no longer dynamically updated, but one CSS file is imported.
(Future build processes will narrow down the CSS file further to only include what’s used). See more details here.
The <scroll-content> element, which is internal to <ion-content>, has been renamed to
<div class=”scroll-content”> since it was neither a directive nor a web component.
<ion-fixed> has been removed, use <div ion-fixed> instead.
scss: Changes to how sass/scss is imported. See more details here.
typings: We have stopped using the typings tool and have migrated to npm @types. See more details here.
