Sucrose 0.90 Release Notes

What is new for users

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 will add three default Ad-hoc networks, for channel 1, 6 and 11. They will be 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.

Tomeu Vizoso from Collabora has been doing a great work to remove the Presence Service. There are no visible changes for the user but the overall collaboration experience should be more stable.

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.

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. The idea is that after the circle becomes too large, rather than shrinking the icons, it morphs into a spiral.

Andrés Ambrois has been adding new filtering options to the Journal. You can sort 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.

Daniel Drake has been adding keybindings for the Frame (F5) and the Journal (F6). This will help to access those important views quicker on hardware where there is no designated key.

Turtle Art

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 Activities

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.

Activity	Description
Dr. Geo	Dr. Geo is an interactive geometry activity. Dr. Geo allows one to create geometric figure plus the interactive manipulation of such figure in respect with their geometric constraints. It is usable in teaching situation with students from primary or secondary level. It is simple and effective with some unique features as scripting and Smalltalk programming.
Pukllanapac	A puzzle: Move the pieces until the circles are all solid circles.
Constellations Flash Cards	This program teaches the constellations by means of a flash-card-like interface. The program draws a constellation and the student has to pick the correct name from a list of five possible choices.
gtranslator	A Sugarized version of the translation file editor "Gtranslator" The GTranslator activity allows to translate the po files locally. This should allow users without a permanent Internet access to translate off-line the localization files downloaded from the Pootle translation server and to contribute to the localization of Sugar to their own language.
Words	A multi-lingual dictionary with speech synthesis.
VNC Launcher	This activity helps you broadcast your screen to another computer. It will automatically launch a VNC server (X11vnc) and display your IP address. You can then connect and view the screen of Sugar on another conmputer using any VNC client (e.g. TigerVNC, UltraVNC Viewer, RealVNC, etc).
Sun Moon Music	Sun-Moon Music MC - Realtime Sonic Environments for Children, Multiple MIDI Controller version. Collaborative exploration and performance encouraged. Requires 1 or more MIDI controllers. This version of Sun-Moon Music is especially designed for collaborative exploration and performance. All MIDI control devices must be set to the same channel.
Get Books	The Get Books activity lets users search and retrieve books from a variety of sources (Internet Archive, Feedbooks, etc). It supports the OPDS protocol for book discovery.
Star Chart	This activity will display a map of the sky showing the position of the visible stars, some of the larger and brighter deep-sky objects (DSOs), the "classical" planets, the sun and the moon.
XaoS	XaoS is an interactive fractal zoomer. It allows the user to continuously to zoom in or out of a fractal in a fluid, continuous motion. This capability makes XaoS great for exploring fractals, and it’s just plain fun!
Turtle Art Mini	Turtle Art Mini is a simple graphical programming environment. It is modeled on the Logo programming language and it emphasized graphical expression by learners new to programming. (Turtle Art Mimi is a subset of the Turtle Art activity – AKA Turtle Blocks)
Super Tux	A Sugar clone of the Super Tux game.
Abacus	Abacus is a simple, customizable abacus activity for Sugar.
Slide rule	Sliderule is a simple, customizable slide rule activity for Sugar.

What's new for developers

The following changes are important for developers using the Sucrose 0.90 developer platform.

Widgets

Add ErrorAlert inherited from Alert.

API

Print warnings about the deprecated activity.info fields.

Dependencies

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.

Compatibility

There a no known compatibility issues, as of today.

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