GTK toolkit developers met in Brussels once again for their annual hackfest during FOSDEM week.

Following their latest GTK 4.21 test build for the GNOME 50 beta, GTK developers at the hackfest were discussing and thinking through some of their plans this year.

While previously there was talk of a possible opt-in unstable API for GTK so developers could test new experimental API features, no firm decision there has been reached yet. They did decide though to bump their C runtime requirement to C11 for the GTK 4.24 cycle.
