The main changes in this cycle will be the ported Shell to use GTK+ 3 and Pygobject3 and the touch support in the UI.
What is new for users
The main feature this cycle was the support for touch screen devices. First of all the icons in the Views that do not have a clear primary action have been changed to reveal the Palette on left click or touch. A good example are the Ad-hoc icons. Since hovering over icons to explore their actions is not possible in a touch screen based UI the decision was to change that behaviour. The same is true for the shared activity icons or the buddy icons in the Neighbourhood and Group View.
New frame behaviour
The Frame interaction has been modified, the learner can use three actions to reveal and hide the Frame: move the mouse into one of the corners, use the frame key on the keyboard and a swipe gesture from the top of the screen towards the centre of the the screen.
New hover feedback in the Views
While working on the feedback for a long press on the icons in the Views (Home-, Neighbourhood and Group View) we changed the hover feedback to one coherent style in all Views: if you hover over one icon you get a light grey rectangle in the background of the icon indicating the hover over state. When you click or touch the icon it has a dark grey background.
Alphabetical ordering in the Home View
The icons in the Home View are now ordered alphabetically. This change has been applied to the favourites view and the activities list view.
Search in all Views
There is now the possibility to search in all the Views, the Home, the Group and the Neighbourhood View.
What's new for developers
sugar-build replaces sugar-jhbuild
Thanks to the work from Daniel Narvaez we have a new tool for building Sugar from the sources: sugar-build. This has replaced our previous tool sugar-jhbuild. sugar-build does currently support several distributions out of the box Fedora 17, Fedora 18, Ubuntu 12.10, Debian Wheezy in both 32-bit and 64-bit. And adding a new distributions is possible and documented as well. Try it out, you will love the ease and reliability of this new tool.
Activity Authors guidelines
The most important change is that the GTK+ 2 based sugar-toolkit has been deprecated since Sugar 0.96. 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 RadioTooolButton expects the "icon_name" property instead of the "named_icon". The API of ToolButton, RadioToolButton and ToggleToolButton has been adjusted to override the icon-name property and add an Icon instance with the set_icon_widget method. This change brings consistent behaviour for all those widgets.
Please see as well the 0.96/Notes#API for which API has been removed during the switch from toolkit-gtk2 to toolkit-gtk3, notably is for example the removal of the deprecated _shared_activity member in the activity base class, collaboration might be broken if you do not port that over.
There is a brand new step-by-step guide for developing Activities under Fedora 17.
What's new for packagers
- python-cjson is no longer a dependency of Sugar
- latest libxklavier is a soft dependency
Internationalization (i18n) and Localization (l10n)
Activities that has been ported to sugar-toolkit-gtk3 will not run on older Sugar versions where the new toolkit is not available. Which means latest Browse and Read will not run on Sugar versions < 0.96. This is reflected in the activity providing backend ASLO where the activities are marked >= 0.96 only.

How to contribute with testing
This cycle we want to especially thank the contributors to the GTK+ 3/pygobject3 port of the shell! Thanks to Daniel Narvaez for all his help here.
Many people contributed to this release indirectly, including testing, documentation, translation, contributing to the Wiki, outreach to education and developer communities. On behalf of the community, we give our warmest thanks to the developers and contributors who made this Sugar release possible.
We want to especially thank:
- the Infrastructure team which does all this great work in the background without which the development would not be possible at all,
- the deployments that provide the development team with feedback from the field,
- the Design team which guided the design of features with UI changes or impact on the workflow,
- the Translation team which makes sure that Sugar is enjoyable in the local languages of our users,
- the developers that submit patches for new features and bug fixes and do review other's patches,
- the maintainers that make sure their code is shippable and which provide packagers with new tarballs,
- the packagers which provide distributions with new Sugar packages,
- the SoaS team for providing a Sugar version to test with during the development cycle,
- the testers for finding the small and bigger issues,
- the release team and Development team for coordinating those efforts.
Looking forward to 1.0
In the 1.0 we want to focus on the API and fix all the little Todos and Fixmes we never got around to.
