All free plugin will still remain on the WordPress.org, and will be auto updated using WordPress plugin update as usual. But this is not working for premium plugins since they are not on WordPress.org. So, we decided to make our own update plugin that will do the same for our premium plugins.
Welcome to new and improved Dev4Press website! As you already know, we at Dev4Press are dedicated to creating premium plugins (and soon themes) for WordPress and offer high quality support through tutorials, documentation, support forum and even email support through ticket support system.
