Version 4.21.6 is a regular update that improves operation of webcam uploads on iOS devices. It also contains a fix so that the plugin's admin Notifications are not shown in Comments Dashboard menu page.

It is reminded that the previous version, 4.21.5, introduced a totally new design of the upload form, based on Material UI. Material UI is a React implementation of Google's Material Design and the new elements of the plugin have been entirely created with the latest version of React.
To activate the new design open the visual editor of the upload form, go to the new Themes tab and switch on Enable Material UI. In addition, the plugin provides options to define the basic Material UI colors and activate/deactivate dark mode.

Version 4.21.7 was issued immediately after 4.21.6 to fix a bug with Notifications, crashing the website.
