Dev4Press Updater 3.5 is a new major version that brings support for addons as plugins, improvements to the plugin interface, various other improvements, and a couple of bugs fixed.
Dev4Press products are expanded with addons for plugins, and now, the Updater plugin can work with addons too. Plugins and addons will be marked with the new banner in the corner (as you can see in the image above). Also, there are many updates to the styling, including fixes to the responsive styling, and making the plugin interface look nice on the small screens too.
If you find any more problems with the plugin, please report them in the support forums.
