Featuring improved support for Android devices, support for removing all notification history from the notification widget, support for multiple archives for Plasma Extensions in the Plasma Discover package manager, and improved ZRAM config to work with single-core CPUs, Neptune 5.4 introduces a new dark look and feel called Neptune Dark, along with the Faenza Dark icon theme. Powered by the Linux 4.16.16 kernel, Neptune 5.4 is packed with some of the most recent KDE software, including the KDE Applications 18.04.3 and KDE Frameworks 5.48.0 software suites compiled against the Qt 5.7.1 application framework, but it stays true to the long-term supported KDE Plasma 5.12 desktop environment.
