</div>There were a number of reasons and the development of features that<br>
were needed/wanted at the time was happening in the gtk3 and dependent<br>
libraries space, there was also things like introspection that could<br>
only really come to gst1 and various other advantages (I seem to<br>
remember there's a doc in the wiki somewhere).<br>
<br>
It's taken time but there's the ability to remove most of gtk2/gst0.10<br>
and other bits now in Fedora 20 with gnome3. We could do most of that<br>
too with sugar if the one or two core Activities make the jump (Record<br>
and TurtleBlocks I'm looking at you!) and it would reduce our image<br>
size quite a bit.<br></blockquote><div><br></div><div>Anyone volunteer to help me with the gst0.10 -> gst1.0 conversion? That is why I have not been able to port Turtle (or Measure). I need access to the raw data.</div>

</div>Fedora and I believe a number of other distributions are now planning<br>
the jump to python3 as the default python in the core distro in<br>
upcoming releases. It's taken a while to pick up steam but it's<br>
certainly something that will happen before long. Obviously 2.x will<br>
be around for time to come but it's adding extra deps.<br>

<br>
</div>My understanding was that 2.7 was designed to ease the jump to python3<br>
and in recent releases there's been some features added to ensure it's<br>
more the case now so maybe it should be something that we ensure that<br>
the 2.7 guidelines that are designed for transition to 3 are enforced<br>
to ensure less work later.<br>

<br>
</div>It's in planning, see the recent Gnome designer gathering in Berlin<br>
from last week.<br>
