[Roddygithub]

Closing: same lockstep issue as #2 — a solo glib bump to 0.22 leaves gtk4/gdk4/gio on the 0.20 stack, duplicating the GLib wrapper layers in Cargo.lock. The whole gtk-rs core (glib, gio, gtk4, gdk4, gdk4-wayland, libadwaita, gdk-pixbuf) must move together in one coordinated migration PR. Tracked as a deliberate follow-up.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
