The deepin project, which develops a Debian-based Linux distribution with a custom desktop environment and several applications developed in-house, has announced the release of deepin 15.4. Despite a minor increment in the version number (from 15.3 to 15.4), this is a major release with many improvements and package upgrades: "deepin 15.4 has brand new design for Control Center and desktop. It adopted new blur and transparent style, new interactions for hot corner and window manager, along with selective wallpapers, full-screen installation interface, latest stable kernel version and original Deepin applications. It has added traditional Chinese (Hong Kong) and Amharic language support. The Control Center has brand-new design and interactions; the homepage shows quick-access icons for common settings to make the operation easier and faster. The newly designed installer has full-screen interface, fuzzy background, smart detection, friendly reminder and 'scan QR code for feedback'; you can experience the incredible pleasure of deepin just after drinking a cup of coffee."
