A bit late recap of the 3.20 development cycle, now that we already started working on 3.22, but I guess better late than never
Last time I tried to dispel the notion that GTK+ is dead or dying. Others have also chimed in, and it seems that we’re picking up the pace into making GTK a more modern, more useful driving force into the Linux desktop ecosystem.
Let’s see how much has changed in the six months of the 3.20 development cycle.
Once again, to gather the data, I’ve used the most excellent
tool that Jonathan Corbet wrote for the “Who wrote the Linux kernel” columns
for LWN. As usual, I’ve purposefully skipped the commits dealing with
translations, to avoid messing up the statistics.
You should look at my previous article as a comparison point.
For the 3.20 cycle, the numbers are:
|Version||Lines added||Lines removed||Delta||Contributors|
More or less stable in terms of contributors, but as you can see the number of lines added and removed has doubled. This is definitely the result of the changes in the CSS machinery that have (finally) brought it to a stable as well as more featureful state.
Of the 55 developers that contributed the 271 changesets of GLib during the 3.20 development cycle, the most active are:
|Name||Per changeset||Name||Per changed lines|
|Ignacio Casal Quinteiro||56 (20.7%)||Ignacio Casal Quinteiro||8530 (39.7%)|

Ignacio has been hard at work, helped by Ruslan and Fan, in making 2.48 the best GLib release ever in terms of supporting Windows — both for cross and native compilation, using autotools and the Microsoft Visual C compiler suite. If you can build an application for Windows as reliably as you can on Linux, it’s because of their work.
For GTK+, on the other hand, the most active of the 81 contributors are:

Benjamin has worked on the new CSS gadget internal API; Matthias, Cosimo, and Timm have worked on porting existing widgets to it, in order to validate the API. Lapo and Jakub have worked on updating Adwaita and the other in tree themes to the new style declarations.
Carlos Soriano has worked on the widgets shared between the file chooser dialog and Nautilus.
Carlos Garnacho has worked on the input layer in GDK, in order to make it behave correctly under the new world order of Wayland; and speaking of Wayland, Carlos, Jonas, and Olivier have worked really hard to implement all the missing features in the Wayland backend, as well as the fallout of the Wayland switch when it comes to window sizing and positioning.

As usual, GLib is a little bit more diverse, in terms of employers, because of its versatility and use in various platforms.

Not many changes in these tables, but if your company uses the GNOME core platform and you wish to have a voice in where the platform goes, you should really consider contributing employee time to work upstream.
It is also very important to note that, while Red Hat still retains the majority of commits, the vast majority of committers are unaffiliated.
The command line I used for
git log \ --numstat \ -M $START..$END | \ gitdm -r '.*(?<!po)$' -l 20 -u -n
For GLib, I started from commit 37fcab17 which contains the version bump to 2.47, and ended on the 2.48.0 tag.
For GTK+, I started from commit 2f0d4b68 which contains the first new API of the 3.19 cycle and precedes the version bump, and ended on the 3.20.0 tag.
The only changes to the
gitdm stock configuration are the addition of a
couple of email/name/employer association; I can publish them on request.
