The Application Kit packages have been released with a minor version v21.8.

This release includes several new features that we would like to present:

  • New policy option for configuring the audience field when integrating your Custom Application with an external API.
  • Improved accessibility of different elements using ARIA attributes.
  • Simpler and more readable list of time zone data, available from the @commercetools-frontend/l10n package.

As always, if you have questions or feedback you can open a GitHub Discussion or a GitHub Issue.
