The Application Kit packages have been released with a minor version 
v21.3.This release includes several new features that we would like to present:
- New CLI commands 
loginandconfig:syncto help maintaining Custom Applications. - New layout UI components 
<TabularMainPage>and<TabularDetailPage>. In addition to that, a new<TabHeader>component is exported from the@commercetools-frontend/application-componentspackage to be used in the tabular UI components<TabularModalPage>,<TabularMainPage>and<TabularDetailPage>. - New ESLint config 
@commercetools-backend/eslint-config-nodefor Node.js projects with built-in TypeScript support. - The notification components now support the aria role 
alertdialogand thearia-describedbyattributes. This helps in particular to write more specific and relevant selector in tests.
