ISO images with the latest version of COSMIC are available for testing, built on top of the alpha builds of the upcoming Pop!_OS 24.04 distribution for systems with NVIDIA GPUs (3 GB) and Intel\/AMD (2.6 GB). Ready-made packages are also available for Fedora, NixOS, Arch Linux, openSUSE, Serpent OS, Redox, and CachyOS.      <\/p>\n<p>COSMIC is evolving as a universal project, not tied to a specific distribution and compliant with Freedesktop specifications. The Iced library is used to build the interface in COSMIC, which employs safe types, a modular architecture, and a reactive programming model, offering an architecture familiar to developers experienced with the declarative interface-building language Elm. Several rendering engines are provided, supporting Vulkan, Metal, DX12, OpenGL 2.1+, and OpenGL ES 2.0+. Developers are offered a complete set of widgets, the ability to create asynchronous handlers, and the use of responsive layout for interface elements based on window and screen sizes. The project is also developing a compositor. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/\"   title=\"server\" data-wpil-keyword-link=\"linked\">server<\/a> cosmic-comp based on Wayland.         <\/p>\n<p>Key changes compared to the third alpha version of COSMIC:  <\/p>\n<ul>\n<li class=\"l\"> A page has been added to the configurator for selecting the interface language and formats for date, time, and numbers.    <center><img decoding=\"async\" alt=\"Fourth Alpha Release of the COSMIC Desktop Environment\" src=\"\/wp-content\/uploads\/2024\/12\/f50b459e90bc787622a10bf699c2b12a.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> A page has been added to the configurator for configuring default applications to launch, such as the browser, file manager, email client, music player, video player, image viewer, and calendar-scheduler. The new COSMIC Media Player, developed in Rust, is utilized for sound and video playback.    <center><img decoding=\"async\" alt=\"Fourth Alpha Release of the COSMIC Desktop Environment\" src=\"\/wp-content\/uploads\/2024\/12\/9fc2b9c524f2ccf3aaafe76257ea6df3.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> The development of the proprietary application manager 'COSMIC Store' has continued, where during the installation or update of applications, you can now view the list of all running and completed tasks (a new context menu 'Details' has appeared in the lower left corner).    <center><img decoding=\"async\" alt=\"Fourth Alpha Release of the COSMIC Desktop Environment\" src=\"\/wp-content\/uploads\/2024\/12\/87d3483d575558e7eb68ed546bce5c15.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> The power management interface now includes separate settings for switching the screen to sleep mode when operating on battery or connected to a stationary power source.

In addition to keeping VRR constantly enabled, there is an option to activate VRR only for fullscreen applications.\n<li class=\"l\"> Issues leading to high CPU load, freezes, and memory leaks have been resolved.\n<li class=\"l\"> A vulnerability that allowed bypassing the screen lock and accessing the desktop without authentication after an emergency shutdown of the composite process has been fixed. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/dts-los-angeles\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3955\">server<\/a> and the cosmic-greeter component, which displays the system login screen.
