Sucrose 0.90 Release Notes
Sucrose 0.90 is the latest version of the Sugar learning platform: Sugar promotes collaborative learning through Sugar Activities that encourage critical thinking, the heart of a quality education. Designed from the ground up especially for children, Sugar offers an alternative to traditional “office-desktop” software. Furthermore it provides a flexible and powerful platform for activity developers.
Sugar is Free and Open Source Software and consists of Glucose, the base system environment; and Fructose, a set of demonstration activities. This new release contains many new features, performance and code improvements, bug fixes, and translations.
What is new for users
Remove the Presence Service
Collabora has sponsored Tomeu Vizoso to replace the Presence Service with components from the Telepathy framework. There are no directly visible changes for the user but the overall collaboration experience should be more stable and this work paves the way for future enhancements in this area.
Sugar Ad-hoc networks
To mimic the mesh behavior on devices where mesh hardware is not available and make the "under a tree"-scenario possible the Sugar Ad-hoc networks have been added. The Feature adds three default Ad-hoc networks, for channel 1, 6 and 11. They are represented with designated icons in the neighborhood view. Simon Schampijer from OLPC has been working on this Feature and back ported it as well to Sugar 0.84.
Enhanced color selector
A new color selector is available for the control panel, thanks to the ongoing efforts of Walter Bender and the design team. Originally proposed for 0.88 this Feature went through several design iterations and finally consensus was reached. Now, we are excited to hear what the learners think about it. The color-selector in the "About Me" control panel section has been modified to allow the user to cycle through different combinations of stroke and fill colors. This replaces the "random" color selector.
Spiral Home View
Walter Bender has been working on another Feature during this cycle. The Spiral Home View is an enhancement to the Home View to enable the display of more icons. If the circle becomes too large, rather than shrinking the icons, it morphs into a spiral.
New ordering options in the Journal
Andrés Ambrois has been adding new filtering options to the Journal. You can order now by size, creation date and modification date. The Feature originally implemented for Dextrose and sponsored by activity central has been found it's way successfully into 0.90, too.
New Keybindings for the Frame and the Journal
Daniel Drake has been adding keybindings for the Journal (F5) and the Frame (F6). This will help to access those important views quicker on hardware where there is no designated key.
The most visible changes are the incorporation of some new blocks, such as the 'Fill' block for created filled polygons, Gray, Black, and White blocks, and the 'Turtle Sees' block, that enables the turtle to directly interact with its canvas. There is also a new site for uploading and downloading Turtle Art projects.
Please see 0.90/TurtleArt for more details.
Sugar 0.90 includes the latest Etoys release. Some of the new features in Etoys 4.1 are DrGeo, speech bubbles, a timer tile and persistent preferences. Also, the QuickGuides have been translated into several languages.
An important change is that projects are not saved automatically anymore when you exit the Etoys activity. Instead of the regular Stop button, you will see an Exit button:
Find out more in the Etoys 4.1 release notes.
While we bundle a small subset of the Sugar Activities within Sucrose, most of the Activity "activity" can be tracked by visiting the Sugar Activity Library.
We have recently surpassed 3.6-million Sugar Activity downloads! There are hundreds of activities available for download in a variety of categories!
Thanks to all the activity maintainers and developers for making this happen.
|Category||No. of Activities|
|Search & discovery||36|
|Chat, mail and talk||6|
|Maths & science||85|
|Maps & geography||5|
What is new for distributors and deployers
What's new for developers
The following changes are important for developers using the Sucrose 0.90 developer platform.
An ErrorAlert has been added. You should use it when you want to notify the user about an error. Besides the title and the message it only has an 'Ok' button for dismissing the alert. It is currently used by notifying the user when an error occurs while copying files to external devices.
Sugar does print warnings about the deprecated activity.info fields. Please adjust your activity.info file as soon as possible.
New API has been added to telepathy-gabble and telepathy-salut to support the work on the collaboration framework, which results in needing 0.9.16 for tp-gabble and 0.3.13 for tp-salut.
One of the goals of the collaboration refactoring was dropping functionality in sugar that has been implemented in telepathy-mission-control, so Sugar now depends on tp-mission-control 5.4.3.
Activity Authors guidelines
There are still many activities that do not use the new activity toolbars introduced in 0.86. We encourage the switch to use the new toolbars as there have been huge improvements in usability (e.g. stopping an activity).
Jim Simmons has written a guide to writing Sugar Activities (Please see Make your own Sugar Activities!) which details how to convert your activity to the new toolbars without compromising performance on old Sugar systems.
What's new for packagers
New API has been added to telepathy-gabble and telepathy-salut to support the work on the collaboration framework, which results in needing 0.10.2 for tp-gabble and 0.3.13 for tp-salut.
One of the goals of the collaboration refactoring was dropping functionality in sugar that has been implemented in telepathy-mission-control, so Sugar now depends on tp-mission-control 5.6.0.
Internationalization (i18n) and Localization (l10n)
still to come...
There a no known compatibility issues, as of today.
Update to this version
Please use the instructions for your distribution (SoaS, Fedora, Ubuntu, Debian etc) of choice to upgrade to this release. Note that it may take a while until the release is packaged for each distribution. Please stay tuned for distribution specific announcements and watch out for updates at Get Sugar.

Looking at the release cycle details
You can browse the notes of each development release in 0.90/Roadmap#Schedule. Their respective sources are listed there as well.
Looking Forward to 0.92
Port Sugar to Gnome 3
Sugar's development cycle is synchronized with the GNOME cycle. GNOME does switch to GTK+3 in the next cycle. This change includes that the Python bindings for GNOME will be available dynamically through GObjectIntrospection rather then through the current static bindings provided by PyGTK. Even so you can install GTK+2 and GTK+3 in parallel, we think it is best to move forward as we can not guarantee that the current bindings are maintained that well and new APIs such as GSettings are unlikely to be wrapped. So a goal for 0.92 will be to port Sugar and all the activities to GNOME 3 through GObjectIntrospection.
Planning of the next release cycle has started at 0.92/Roadmap.
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,
- the maintainers that review patches and 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 during the development cycle a Sugar version to test with,
- the testers for finding the small and bigger issues,
- the release team and Development team for coordinating those efforts.
