Key releases include gdk-pixbuf 2.44.5 with glycin-based XPM/XBM loaders and GTK 4.21.5 featuring SVG filter support in CSS and GSK renderer refactoring. Session saving support was deferred due to API issues. Discussions covered unstable APIs, bumping the C runtime requirement to C11, and improving project maintenance via automated issue tagging. GTK3 changes will be limited to crash and build fixes. Accessibility topics included concerns about AccessKit's GTK implementation, AT-SPI feature negotiation gaps, ARIA's stringly-typed attributes, and a LibreOffice request for an AT-SPI collection interface wrapper. Plans for the next cycle include reviving session saving, AT-SPI collection support, GtkDropDown API gaps, and bringing libadwaita APIs back to GTK. ## Full article daily.dev links to this article rather than hosting it.
