GTK+ 3.22.13 is a maintenance release that adds a month’s worth of fixes and updated translations from various contributors. The bug fixes are typically small but significant and include a memory leak fix for the Wayland display server when exporting handle, a memory leak fix for linkbutton, and a quartz backend segfault fix, which was a regression from last month’s point release, GTK+ 3.22.12. Harmless clang warnings were patched for the Wayland display server, along with an increase of key delivery’s verbosity. GTK+ 3.22.13 also makes it possible for the GtkVolumeButton widget to no longer be limited to 10 values, allows opening in window or new tab to work on unmounted filesystems, and adds an extra layer of padding between label and checkbox for the popover.
