Release of the Sway 1.5 user environment using Wayland

Prepared release of the composite manager Sway 1.5, built using the Wayland protocol and fully compatible with the tiling window manager i3 and the panel i3bar. The project code is written in C and is distributed is licensed under MIT. The project aims to be used on Linux and FreeBSD.

Compatibility with i3 is provided at the level of commands, configuration files, and IPC, allowing Sway to be used as a transparent replacement for i3, utilizing Wayland instead of X11. Sway allows windows to be organized on the screen logically rather than spatially. Windows are arranged in a grid that makes optimal use of screen space and allows for quick manipulation of windows using only the keyboard.

To create a full-fledged user environment, the following accompanying components are offered: swayidle (background process implementing the KDE idle protocol), swaylock (screensaver), mako (notification manager), grim (screenshot creation), slurp (screen area selection), wf-recorder (video capture), waybar (application panel), virtboard (on-screen keyboard), wl-clipboard (clipboard management), wallutils (wallpaper management).

Sway is being developed as a modular project built on top of the library wlroots, which encapsulates all basic primitives for organizing the work of the composite manager. Wlroots includes backends for
abstracting access to screens, input devices, rendering without direct calls to OpenGL, interacting with KMS/DRM, libinput, Wayland, and X11 (providing a layer for running X11 applications on Xwayland). In addition to Sway, the wlroots library is actively used in other projects, including Librem5 and Cage. In addition to C/C++, bindings have been developed for Scheme, Common Lisp, Go, Haskell, OCaml, Python, and Rust.

In the new release:

• Added the ability to dynamically organize output on headless systems using the create_output command (can be used to set up remote access to the desktop through WayVNC).
• Through Wayland protocols input-method and text-input, support for input method editors (IME) has been implemented.
• The possibility of enabling adaptive synchronization (VRR, Variable Refresh Rate) has been provided to reduce image stuttering in games.
• Support for the viewporter protocol has been added, allowing for improved performance and quality in older games.
• Virtualization and remote desktop access systems are now able to intercept keyboard combinations.
• Support for the protocol wlr-foreign-toplevel-management, allowing the connection of custom panels and window switches.
