Release notes

Lovelace 1.21.4 changes the DropZone component of the @ada-cx/lovelace design system.

• DropZone no longer renders a hidden keyboard drop button. That button was a Tab stop, and focus on it opened the drop panel.
• The drop panel shows only while a drag is over the zone.
• label is now the panel heading only.

If your interface uses DropZone, also give a control that opens a file picker. Keyboard and screen reader users attach files with that control. See DropZone.
