TL;DR
IceWM released version 4.0 with incremental improvements and several bug fixes, while Budgie 10.10 is presented as the first fully Wayland-native Budgie and drops some X11 components. A separate, experimental X11 server called Phoenix — written in Zig and not a fork of X.org — also surfaced late in 2025.
What happened
Early January brought three notable moves in the Unix-like graphical stack. On January 1 the long-lived IceWM project issued version 4.0, marking another step in a project whose first public release dates back to 1997; this update tweaks Alt-Tab window switching, defaults to 32-bit RGBA color, and remedies several bugs including OpenBSD keyboard-layout switching. Ten days later the Budgie desktop published version 10.10, described as the first entirely Wayland-native Budgie release; it removes some X11-specific pieces, integrates components drawn from environments such as Sway, and introduces a Budgie Desktop Services module implemented with Qt 6. Separately, a very early new X11 server named Phoenix appeared at the end of 2025. Phoenix is an independent project implemented in the Zig language and aims to support a focused subset of the X11 protocol for more modern applications.
Why it matters
- Shows parallel activity at both ends of the display stack: continued maintenance of legacy X11 tooling alongside projects moving to Wayland.
- Budgie’s Wayland-native build signals wider desktop-environment migration efforts and new compositor compatibility options for users.
- A fresh X11 server written in Zig indicates X11 remains a living part of Unix-like ecosystems and continues to attract new development.
- Changes like Budgie’s use of Qt 6 for orchestration reflect cross-toolkit mixing and evolving architecture choices in desktop projects.
Key facts
- IceWM 4.0 was released on January 1 and traces its project history back to a 0.8.9 release in 1997.
- IceWM 4.0 improves Alt-Tab behavior, defaults to 32-bit RGBA color, and fixes several bugs including keyboard-layout switching on OpenBSD.
- Budgie 10.10 followed about ten days later and is presented as the first fully Wayland-native release in the Budgie 10 series.
- Budgie 10.10 recommends wlroots-based compositors and specifically highlights effort to support the labwc compositor.
- The Budgie 10.10 release drops some X11-specific components and borrows tooling ideas from projects such as Sway for tasks like wallpaper and screenshots.
- Budgie’s new Budgie Desktop Services module is implemented in Qt 6.
- Budgie 10.10 is slated to be included in Fedora 44 and Ubuntu Budgie 26.04 (the latter not being a full five-year LTS flavor).
- Phoenix is a new, very preliminary X11 server that debuted at the end of 2025; it is written in Zig and is not a fork of X.org.
- Phoenix aims to be simpler than Xorg by supporting a subset of the X11 protocol intended for relatively modern applications.
What to watch next
- Progress and adoption of Budgie 11 and its roadmap — not confirmed in the source
- Maturity and uptake of the Phoenix X11 server across distributions and projects — not confirmed in the source
- How widely labwc or other wlroots-based compositors are used with Budgie in distributions beyond the ones cited — not confirmed in the source
Quick glossary
- X11 (X Window System): A long-established network-transparent windowing system for bitmap displays used on many Unix-like operating systems.
- Wayland: A modern protocol and architecture for compositors and clients to manage display windows and input on Linux and similar systems.
- Compositor: Software that combines buffer content from applications to produce the final display output, often providing window management and effects.
- Window manager: A component that controls the placement and appearance of windows within a graphical user interface.
- Qt 6: A cross-platform application and UI framework commonly used to build graphical user interfaces and desktop components.
Reader FAQ
Is Budgie 10.10 fully Wayland-native?
Yes; the release is described as Budgie’s first entirely Wayland-native version.
Does IceWM 4.0 represent a complete rewrite?
No; the project’s version history and release notes suggest the major-version bump is largely numerical with incremental improvements rather than a full rewrite.
Is Phoenix a fork of X.org?
No. Phoenix is an independent new X11 server and is not a fork of X.org.
Will Budgie 10.10 be available in major distributions?
The source confirms Budgie 10.10 will be part of Fedora 44 and Ubuntu Budgie 26.04.
