Sucrose 0.86 Release Notes

Introduction

Sucrose 0.86 is the latest version of the Sugar education platform, consisting of Glucose, the base system environment; and Fructose, a set of demonstration activities.

Sucrose is released every six months and contains many new features, improvements, bug fixes, and translations. Sucrose 0.86 continues this tradition and is our third 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.

What is new for users

Activity Toolbar redesign

The activity toolbar has been redesigned. The previous design using small text tabs to group toolbar options together caused a number of reported difficulties. More details about the Features/New Toolbar Design. The redesign provides a solution for the " how do I stop an activity" issue, pointed out in #452. Browse, Write, Calculate, Terminal, Read, ImageViewer, and Turtle Art have already been ported to use the new Toolbar design, and many other are underway.

Switch to Metacity window manager

Sugar has switched window manager from Matchbox to Metacity. Matchbox was designed for small devices that run all applications maximized. Sugar can run on devices with larger screens, and some of the more complicated applications (not specifically designed for Sugar) can break when run in Matchbox. Using Metacity instead means that some unsugarized apps will run better inside Sugar.

Flash Activities

Gnash has been added to the Sugar Platform, meaning that authors of education content can use Flash tools to create first class activities for Sugar.

Tabs in Browse

Links that would open in a new window now open in new tabs inside the main activity window, similar to the behavior in other browsers. Though this feature doesn't yet allow the user to explicitly open any link in a new tab, or explicitly create a new tab, it does provide a better experience when using some websites that open multiple windows.

Ad hoc Networking

The new ad-hoc networking facilities allows you to connect with others over wireless in an ad-hoc manner without wireless infrastructure, like an access point. This is the so called "under a tree scenario". OLPC provided for similar functionality with XO hardware based on a mesh network. Ad-hoc networking allows Sugar to use this with most wireless hardware. Furthermore it allows you to share an internet connection using the same mechanism. Fore more details see Ad-hoc network testing.

Read

The read activity now has support for Epub files. For downloading epub content, http://www.feedbooks.com and http://www.epubbooks.com/ are recommended place to start looking. This release will also let you associate (add and edit) notes with your bookmarks, and has a slightly more useful fullscreen view (you can now get a rough idea of how much battery is left in your laptop/netbook without invoking the frame).

Software Update

The software update control panel is now included in standard Sugar, it uses the Sugar Activity Library to check for and install the latest Activity updates available.

Improved Accessibility

Some parts of Sugar (Journal and Home list view) have been switched to use Gtk+ widgets, instead of HippoCanvas, which had no accessibility support. More tools now also show their keyboard shortcuts to help their discovery.

Activities in the activity tray frame, now use palettes that show both the activity name, and its text title.

Keyboard Control Panel Selection

Keyboard layout and model configuration support in the Control Panel.

Home Favourites View Improvements

Resuming and starting new activities from the Home favourites view has been enhanced by simplifying the activity palettes to that activities cant be accidentally deleted, or removed from the favourites view (activity management is now all done via the Home List View). If you want to quickly start a new activity without using the palette, hold the <Alt> key and click an activity icon.

Improved File Transfer

The Journal "Send to friend" feature has been extended to support file transfers via a Jabber server (previously this only worked for local network file transfer). This now allows you to send Journal entries to any available friends you have made, wether you are using a remote Jabber server, or the local network (use the Neighbourhood view to add new friends).

Update to this version

Please use the instructions for your distribution (SoaS, Fedora, Ubuntu, Debian etc) of choice to upgrade to this release.
