The following changes are important for developers using the Sucrose 0.96 developer platform:
=== Activity Authors guidelines ===
The most important change is that the GTK+ 2 based sugar-toolkit has been deprecated. Newly written activities should use sugar-toolkit-gtk3, which is based on GTK+ 3 and Pygobject3, now. There will be only bug fixes being available in the future for the old toolkit no new features will be made available for it and it will probably go away at one point completely. Detailed guidelines for porting existing activities can be found at [[Features/GTK3/Porting]].

The Keep button has been removed completely from the API later; please adjust existing activities accordingly.
