Sucrose 0.88 Release Notes

Introduction

Sucrose 0.88 is the latest version of the Sugar learning platform, consisting of Glucose, the base system environment; and Fructose, a set of demonstration activities.

Sucrose is released every six months. Each new release contains new features, improvements, bug fixes, and translations. Sucrose 0.88 continues this tradition and is our fourth well-planned release to date.

You can learn more about Sugar itself by studying the Sugar definition or by reading the comic strip about the learning platform from Dongyun Lee. Even better, why not try Sugar today?

What is new for users

Connect to the Internet using a GSM modem

You can use a GSM modem with Sugar to connect to the Internet. GSM modems are often found in mobile phones but there are also standalone modems that can be connected over USB to a computer. When a GSM modem is attached to the computer, a device is added to the Sugar Frame from which you can connect to the Internet. The settings for the connection—such as service provider and password—can be made from the Sugar Control Panel. This feature provides Sugar learners with more ways to access the Internet.

Developers and educators from Plan Ceibal and Paraguay Educa worked together to add the GSM feature to Sugar.

With this feature it should be easier for deployments who rely on a small translator team to accomplish their job since they no longer need to keep pace with the Sugar release cycle. Furthermore, we hope to alleviate activity maintainers from the burden of making a new release whenever a new translation becomes available.

A message is displayed when an activity fails to start

In previous versions of Sugar there was no feedback to distinguish between an activity that failed to start and an activity that is slow to launch. Furthermore, stopping an activity that failed to start was not possible from the user interface. This feature displays a message when an activity fails to start with a button to allow to stop the activity.

A refactored, new feature rich Turtle Art

Turtle Art has undergone a major rewrite for this release. Many new features have found their way into this release including Cartesian and polar coordinate grids, support for multiple turtles, resizable blocks, SVG export, and run-time block highlighting.

Cartesian and polar coordinate grids
Collapsible stack
Collapsed stack
Python function with one, two, or three variables
Expandable bullet list (two bullets)
Expandable bullet list (four bullets)
Enlarged blocks
Shrunken blocks
100 Turtles
SVG output using the save SVG block
Multi-variable Python blocks

See Turtle Art 0.88 Release Notes for more details.

Track user preferences for opening activities

An enhancement has been added to Sugar that tracks the most recent choice when opening an object with an activity. A little example should help to outline the new behavior:

1. Open a PDF file using an activity, say SweetPDFReader.

2. Further PDF files are opened using SweetPDFReader by default.

3. Open a PDF file with Read.

4. Further PDF files are opened using Read by default.

Sugar Activities

While we bundle a small subset of the Sugar Activities within Sucrose, most the Activity activity can be tracked by visiting the Sugar Activity portal. (We have recently surpassed 2.5-million Sugar Activity downloads.) There a hundreds of activities available for download in a variety of categories:

Category	No. of Activities
Search & discovery	34
Documents	11
News	4
Chat, mail and talk	5
Media creation	24
Programming	10
Maths & science	76
Maps & geography	4
Media players	1
Games	61
Teacher tools	104

Recent additions include:

Activity	Description
Visual Match	A visual matching game. The object is to find sets of three cards where each attribute—color, shape, number of elements, and shading—either match on all three cards or are different on all three cards.
Erikos	A simple audio pattern-matching game. See if you can follow the audio sequence.
Sugar Commander	Sugar Commander is a utility for working with the Journal. You can easily add files as Journal entries, view and update title, description, and tags for entries and delete entries you no longer need.

What is new for distributors and deployers

Customize the Sugar font size

This Feature adds the possibility for distributors and deployers to customize the Sugar font size. The proposed solution is one similar to the solutions used in other desktop environments like GNOME and KDE: allow customization of the base font size used across the entire desktop platform. This is another important step to bring Sugar more in-line with the desktop world and distributors like OLPC will be able to select font sizes without ugly hacks. In Sugar 0.90 there will be a new control panel section that users will be able to customize font size to suit their needs, too.

Update an activity translation independently of the Sugar release process

In general the translation process is tightly coupled with the release workflow. In order to get the latest translations for a particular activity, deployments need either to wait for the activity maintainer to provide a new release or to use the language-pack mechanism, which is distribution specific (and at its best an ugly hack). The Enhanced Gettext Feature adds an extra search path for the translation files of Sugar activities. This allows deployments to add and update activity translations independently of the release process. The alternate search path can be configured using GConf configuration system.

What's new for developers

The following changes are important for developers using the Sucrose 0.88 developer platform.

Widgets

API

Dependencies

As Sugar has been going back to use simplejson we encourage activity authors to use simplejson in their activities, too.

Activity Authors guidelines

What's new for packagers

sugar: cjson -> simplejson: Sugar moved back to use simplejson instead of cjson. cjson has a big bug dealing with slashes, this is a significant long-term bug and upstream has not been responsive other than acknowledging it. This bug breaks journal entry bundles #1553.

sugar-toolkit: the python module dateutil has been added. Please add this to the requires (i.e. in Fedora python-dateutil).

Internationalization (i18n) and Localization (l10n)

More than 80% of the core sugar user interface and toolkit has been translated to 23 languages, which are (in order of percent translated):

Vietnamese
Spanish
Portuguese (Brazil)
Papiamento
Japanese
Italian
Greek
German
French
Chinese (Taiwan)
Arabic
Hindi
Dutch
Swedish
Portuguese
Indonesian
Tamil
Sinhala
Pashto
Slovenian
Russian
Nepali
Dari

This work has been made possible thanks to the tireless efforts of the members of the translation team.

Compatibility

Migrating the datastore from learners using Sugar 0.82 was broken in 0.86. A fix has been going into 0.88 to migrate the datastore fine. 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.
