I wouldn't agree with that. gtk+-2 is still maintained (the latest maintenance release is 4 days old) and is a far more stable target. The introspection bindings for gtk+-3 break at regular intervals (I gave up on trying write minor tools using gjs/introspection about 2 years ago because of it), and the theming breaks with every release. Theming is not necessarily an issue for many programs, but introspection is. Possibly things might be settling down with gtk+3 now but I have not seen any announcement that these are considered stable now. Until there is more stability I doubt there is any prospect of the big non-gnome gtk+ applications I use (claws-mail, firefox and libreoffice) moving to gtk+-3.

Re: Can I install both GTK+2 and GTK+3?
Thanks Emmanuele. Yes, providing a grace period for users is exactly what I had in mind. For example, since lots of people are less than enthused about Unity, there are quite a few Ubuntu 10.04 users still out there, and the Ubuntu repository only serves up GTK+2 for that. I suppose people might be able to build GTK+3, but that's likely a lot of work. So had in mind producing two binaries for the distribution tarball.

The more we care about code which others have written in the past, and not breaking their code by our fixing of bugs the more we build trust. Anyway, I'm sure this trust is getting stronger the more that applications do port to GTK+3 and the more GTK+3 matures. I.e. it's hard to fix back-compat problems when nobody files bugs about them, the more applications which do port, the more bugs get filed, and the more awareness is raised in general. It's that awareness which helps us to pay attention to older applications, helps us to avoid breaking older applications (which are just as important as newer applications).

Re: Can I install both GTK+2 and GTK+3?
Hello people,
Apologies if this is the wrong place to post my questions, but they
involve Ubuntu 13.04 and GTK+ as well. A few weeks ago I finished
porting my program for the speech-impaired to Ubuntu 12.04 LTS.
This is intended for the OLPC project and also runs on Fedora. Now
that my program runs on 12.04 I figure it should work on 13.04 LTS
without any mods.
In previous versions of Ubuntu, upgrading to the next LTS was
nothing more than a few mouse clicks but not now. Does anybody on
this gtk list who uses Ubuntu have any idea where I am messing
up? My other question involves porting my speech program to
laptop.org. Several other hackers have helped with the gtk code;
it is mostly 3.x. The nutshell is: should I just hand my
program to the sugar-devel folk and be willing to help with
what it needs {espeak, [g]vim, and whatever else} or what?
thanks for any help,
gary
