Miracle-WM as the Wayland compositor / window manager built atop Canonical's Mir project is out with a big new feature release. This "hackable" and i3/Sway-inspired Wayland compositor has landed a WebAssembly-based plug-in system for opening up new possibilities as well as a new Rust API with this week's v0.9 release.

Miracle-WM 0.9 introduces a WebAssembly-based plug-in system that can configure window management, animations, configurations, and more. With loading as WASM payloads it should be more secure and portable than alternatives. Miracle-WM developer Matthew Kosarek has provided a video of the WASM plugins in action:

Miracle-WM 0.9 also brings a new Rust API for those wanting to write plug-ins for Miracle using the Rust programming language.

Some other new changes include cursor theme support. a new key sequence to support reloading the Miracle configuration, performance improvements, and a variety of other updates and new features. Plus bug fixing too.
