Mir 2.29 update includes new protocols and improvements for Wayland-based shells, such as xdg-dialog-v1 and ext_foreign_toplevel_image_capture_source_manager_v1.

Why it matters

This update is important for developers and users of Mir, a compositor for building Wayland-based shells, as it adds support for new protocols and improves existing ones.

Mir 2.29 lets apps tell the window manager when they're showing a dialog box, and it lets clients take screenshots of specific windows for things like recording.
