Notices by GTK (gtk@floss.social)

Reminder: instead of using StackOverflow for your questions about GTK and the GNOME software stack, use the GNOME Discourse instance:

https://discourse.gnome.org

You can also use it for applications and the overall GNOME desktop.

Important security update for GLib and D-Bus, thanks to @pwithnall

If you are a downstream distributor of GLib, GTK, or GNOME-related projects, remember to follow the distributor tag on Discourse.

Matthias Clasen has written a post on the GTK blog about recent changes in the accessibility implementation of the toolkit, as well as improvements in the tooling planned for the 4.12 release: https://blog.gtk.org/2023/06/21/evolving-accessibility/

It's important to note that more work is needed to improve the accessibility stack on Linux; if you want to contribute you can read the at-spi2-core developers documentation for an overview of the stack: https://gnome.pages.gitlab.gnome.org/at-spi2-core/devel-docs/index.html

We especially need more documentation on how ATs interpret the accessibility interfaces, and what kind of expectations should be satisfied by toolkits and apps.

We are dropping the Autotools build for GTK 3.x, and have fully switched to Meson. If you package GTK 3 and you are still using Autotools, now is the time to switch.

For more information, see the announcement on Discourse: https://discourse.gnome.org/t/removing-the-autotools-build-for-gtk-3/12764

To those still wondering what kind of performance improvement Meson brings to an established project over Autotools, here are some numbers from the Yocto project after they switched their native GTK3 build recipe:

config (autotools): 38.5s
config (meson): 17.9s (-53.5%)
install (autotools): 11.2s
install (meson): 1.6s (-85.5%)
compile (autotools): 100.8s
compile (meson): 37.5s (-62.8%)

The build went from over 2 minutes to sub-1 minute
