Sucrose 0.92 Release Notes


Sucrose 0.92 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

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.



Activity Authors guidelines

There are still many activities that do not use the new activity toolbars introduced in 0.86. We encourage activity authors 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 while still keeping backward compatibility with older Sugar versions.

What's new for packagers

Internationalization (i18n) and Localization (l10n)


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.

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,
