commit 7dc28cfb9a0e216c5cf606ef785d3ae7bb3a8a7e Author: Simon McVittie <smcv@debian.org> Date: Fri May 16 11:05:07 2025 +0100 d/libgtk-4-doc.links: Remove unused, dangling symlinks to GLib docs commit 7469dd3f6374c9149f1f63013c4b06345e4e5128 Author: Simon McVittie <smcv@debian.org> Date: Thu May 15 13:48:18 2025 +0100 d/libgtk-4-1.bug-control: Add known out-of-tree IM modules to Package-Status There are considerably fewer of these than GTK 3 modules, because GTK 4 does not support arbitrary GTK_MODULES, but they could still be involved in crashes; so it seems wise to diagnose them as "packages libgtk-4-1 is related to" in bug reports.
