Miracle-WM 0.9 Makes This Mir-Based Wayland Compositor Truly Hackable

Miracle-WM, the Mir-based Wayland compositor built around a tiling window manager, has released version 0.9. With this update, the project takes a significant step toward modularity by shifting much of its extensibility into plugins, positioning itself as a more customizable and hackable platform rather than just a visually polished tiling environment.

In addition to the new plugin-focused approach, the release introduces cursor theme support, performance enhancements, and automatic reloading of display configurations when changes are detected. Configuration reloading behavior has also been updated—users must now manually reload configurations using the Meta + Shift + R shortcut instead of relying on automatic reloads.

This version includes an important breaking change for existing users. Configurations that previously depended on Linux keycodes for custom actions and keybinding overrides must now switch to human-readable XKB keysym names.

On the bug-fix front, Miracle-WM 0.9 addresses several noticeable issues, such as dialogs and popups being incorrectly tiled, inconsistent pointer-based resizing behavior, and timing glitches in window opening animations.

Additionally, the changelog highlights extensive improvements across multiple areas, including floating window behavior, workspace management, display rotation handling, locking and deadlock fixes, plugin input processing, and overall animation quality.

For more details, see the changelog.

The project says Debian and Snap builds for Miracle-WM 0.9 are expected later this weekend.
