Before you update to this release

Before you update to this release, please:

• If you are in a school or other deployment, make sure you contact your technical support team before updating. Some deployments have special configurations which will need special steps taken before update. Your deployment may not yet support this release.
• Determine which release you are on and whether you plan to update over the Internet or via USB stick. The available upgrade options are listed below.
• Determine the version of your activities. Decide if you need to re-install or update them and make sure you have access to updated versions if required. See the list of activities you must update.

Full instructions are are in the upgrading from previous releases section of this document.

New features in 8.2.0

In addition to fixing bugs, we've added lots of new features to our 8.2 release, including

• GUI and usability improvements
• Activity update
• Backup and restore to school server
• Longer battery life
• New Translations
• An update to Fedora 9 for our base system
• Improvements to activities.

GUI and usability improvements

A number of aspects of the Sugar UI have been revamped to improve the user experience.

Home view

We've made a number of improvements to the home view to make it easier to manage and launch activities.

There are now three distinct view options:

• 

  Home Freeform view

• 

  Home Ring view

• 

  Home List view

Freeform

This view shows only favorite activities. The activity icons can be positioned by dragging them around the screen.

Ring

This view shows only favorite activities. The activities are kept neatly ordered within a ring surrounding the XO.

List

This view shows every activity currently installed on the laptop, as well as other info about them such as their installation date and version number. The search field allows children to easily locate an activity in the list. Favorite activities can be specified here by starring them.

Launching activities

In the new design, the Home view serves as a space for launching new activities. By contrast, the Frame now contains the running activities which used to appear in Home. This change solidifies the zoom levels as places for initiating new objects and interactions. Clicking on an activity icon will launch it, revealing a brand new launching behavior which provides strong and immediate feedback, with the familiar pulsing icon in the center. This feedback discourages children from launching many activities at once. (They can leave the launcher via the zoom buttons/keys to start others, if they wish.)

Removing activities

Activities can be individually erased to free up space for new Activity course material

By hovering over the activity icon it's possible to take other actions as well. For instance, one may easily add or remove it as a favorite activity, or remove the activity completely, uninstalling it permanently. To prevent accidental deletion, a confirmation step is required when deleting activities.

Frame

The new frame provides more useful content relevant to the current state of a child's interaction with the laptop. The edges of the frame represent, clockwise from the top: places, people, devices, and objects. Each of these edges provides useful information and interactions, which can be accessed at any time via the frame key or the hot corners.

The Frame is accessible from anywhere

1. Places

The top edge of the Frame showcases the "places" within the UI a child can navigate to. First and foremost, the zoom level buttons appear here just as they always have. Additionally, the list of currently running activities also appear on the top edge of the frame; the active activity is highlighted. The Journal is always present here as a running activity. Having the active activities in the Frame allows one to easily switch among them with ease, without first returning to Home.

2. People

The right edge serves as an "active buddy list." People with whom a child is currently collaborating appear on the right edge of the Frame.

3. Devices

System status is now readily available in the bottom edge of the Frame. The battery level, network status (including the new mesh device, which allows one to switch channels), and speaker all appear here. Their palettes provide more details, and options such as the ability to adjust the volume.

4. Objects

The left edge of the Frame serves as a multi-item clipboard. Objects such as images and text can be dragged to and from the clipboard and activities, or permanently kept in the child's Journal. The currently selected item (which can be selected with a click) will be pasted when the paste button (or shortcut) is invoked within an activity.

Journal

The 8.2 release includes an updated Journal as well. The changes are subtle, but the look is cleaner and some additional features have been added to make object management easier.

List view

The list view looks a bit different, but hasn't changed too much from how it behaved before. It still contains a list of all of the objects created on the laptop, ordered by date. Resuming an activity is as simple as clicking on the activity icon itself. There are a few enhancements to the Journal list as well:

In-line renaming

It's now possible to rename entries directly within the list view, by clicking on the title text. A text field will appear to receive changes, which can be confirmed or canceled with enter and esc, respectively.

Object palettes

The objects represented within the entries (specifically, activity and people icons) now have palettes attached to them. By hovering over their icons, it's possible to find out more information about them, such as the name of the person, and take actions on them, such as copying or deleting an entry. These changes make it possible to do more from the list, without having to constantly enter the detail view.

Better feedback

The Journal now provides better feedback in edge cases, for instance when there are no search results returned for a query, to prevent confusion.

Details view

By clicking on the details button (the little arrow) at the right of an entry, a child can view the details page for the entry. This includes a preview, editable description and tags, and other info about the entry. The toolbar at the top of the screen provides useful actions for launching, copying, or deleting the entry.

Graphical sugar control panel

Accessible from the pop-up menu of the XO icon in the home view, the control panel currently provides a graphical interface for setting language, power, UI, date and other options. More detailed instructions can be found here.

• 

  Sugar Control Panel
  Graphical interface for setting many XO preferences.

• 

  Language
  Allows selection of the default language.

•

Details on Software Updates Control Panel

This release introduces an automatic updater to help you get the latest Activities. Activities are maintained separately from the core OS, and the updater will help ensure your Activities work well with your new 8.2 core OS. (It is especially important to update your Activities after upgrading from 7.1-series (650, 653, and 656) builds, since otherwise you will see no activities after boot.)

Ensure you are connected to a network, then use the Sugar Control Panel (described above) and click on 'Software Updates' to check for updates to your activities. Select the updates you are interested in (right click to select/unselect all) and click 'Install now'.

You can also subscribe to different "Activity Groups" with interesting collections of activities, by clicking on the "Edit Activity Groups" expander in the control panel. The activity groups page on our wiki lists some interesting activity groups you can try.

For activity authors and developers, technical details can be found at the Software update page on our wiki.

Backup and restore to school server

This feature will automatically backup an XO at least once a day to its registered school server.

To restore a previous backup from the XO, open the Browse activity, click on "Schoolserver", and choose the backup date to which you wish to restore. This is meant for disaster recovery only: all user data will be replaced.

You must use XS version 0.4 (XS Release Notes) or later to take advantage of this feature.

• Detailed Documentation on Backup and Restore

Longer battery life

this is not a supported feature yet, but you can help us try it out and find issues.

This feature is implemented via the Sugar Control Panel. It is off by default so you must enable it in the Sugar Control Panel (click on the 'Power' module) to take advantage of it.

The feature offers two options:

• Automatic power management

This mode dims the screen and turns off the CPU when it switches the laptop to power saving mode. Power saving mode comes on automatically when the user does not interact with the touchpad or keyboard for more than a minute and when no activities are heavily using the CPU on the XO. For example, power saving mode would not be turned on if the video camera is recording or showing video on the screen, regardless of whether the user touches the keyboard or not. The laptop will wake up when a key (or the power button) is pressed or the touchpad is used.

• Extreme power management

This mode turns off the wireless radio. Once this mode is turned on the XO wireless network connection will disconnect. This is the most aggressive power saving mode available when combined with Automatic Power Management, and will give the longest battery life.

A third sleep mode is entered when the lid is closed or the power button is pressed momentarily (holding the power button for more than a few seconds will turn off the laptop completely). This mode differs from the automatic mode in that keypresses and touchpad usage will not wake up the laptop -- to leave this mode, open the lid or press the power button again. The "Extreme power management" mode will still control whether the wireless radio remains on or not when suspend is invoked manually.

Tests show that an XO in full sleep mode will still have power after nearly two days!

Languages and keyboards

OLPC relies on volunteers and country experts for keyboard knowledge and for translations of the Sugar user interface and all the Activities that many contributors have provided. Translations are not tested or approved by OLPC. Both translations and Keyboards must tested and approved by the country designated experts or by volunteers.

Thanks to members of the worldwide OLPC Translation Project, who can be found on the localization mailing list, the following languages show more than 80% of the Sugar interface has been translated:

• Dutch
• French
• German
• Greek
• Italian
• Japanese
• Kinyarwanda
• Kreyol
• Marathi
• Mongolian
• Nepali
• Sinhala
• Spanish
• Telugu
• Turkish
• Urdu
• English

In order to conserve space on the laptops, our builds ship with the following languages:

Fedora 9

We've upgraded our base system to the Fedora 9 release from our partner, Red Hat. The release notes for Fedora 9 describe some of the improvements we've inherited, although builds for the XO do not include all the features of Fedora 9 by default.

More information: <trac>7383</trac>

Improved Flash compatibility

OLPC ships Gnash, an open source flash movie player integrated into the Browse activity. This release updates Gnash to version 0.8.3.

The newer version of Gnash increases compatibility with many sites. For example, Caillou animation rendering was incorrect in previous releases, but now appears to work correctly.

As of build 2301, the Caillou flash animation is mostly not working. I browsed to http://pbskids.org/caillou/immersivegames and it says "errorCode::Failed to load movie or jpeg". Jpritikin 04:03, 22 August 2008 (UTC)

Improvements to activities

Activities start faster than in previous builds.

<trac>7382</trac> Browser Improvements Auto-complete now available!

<trac>6036</trac> Chat enhancement

Upgrading from previous releases

Be sure to read and carefully follow these instructions before you begin the upgrade process, and allocate enough time to do the full process before you begin.

During pre-release development, you will need a developer key in order to install an 8.2 OS image. This key should be copied in the /security directory BEFORE the upgrading process.

Important Note: Please check with your deployment technical contacts before upgrading. Countries using the XO may have custom configurations which may require special actions to be taken before new releases can be installed.

The process described below is to upgrade the XO while it is connected to Internet, for other ways to upgrade, see the Upgrading the XO.

Here are the steps to upgrade:

1. Plug the XO into AC Power
2. Connect XO to the internet
3. Launch the update command
4. Update activities

Step 1: Plug the XO into AC Power

Upgrading could be a long process. For this reason, ensure first that your XO is connected to reliable AC Power. Be sure to have enough time to do the full process (about 1 hour).

Step 2: Connect XO to the internet

During the upgrade process, your XO will download the new release. So you should ensure that the XO is connected to the internet before launching the upgrade. See Connecting Guide or Wifi Connectivity for instructions. Use Browse activity to test your connection.

Step 3: Launch the update command

Open the Terminal Activity or a console and type the following (press the Enter key after it):

sudo olpc-update official-os860 

If the update program successfully connects to the update server, some messages should display similar to this:

Downloading contents of build official-os860
Updating to version hash xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Making clean /versions/updates/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Trying irsync_pristine update from rsync://updates.laptop.org/build-official-os860
- Cleaning tree.
- Fetching contents.
- Performing incremental rsync.
Verifying update.
Installing update in /versions/{pristine,run}/xxxx

This process may take more than thirty minutes. When the process is complete, you need to reboot.

Important Note: On the first reboot after upgrading, the XO will run slowly for about 1 minute. After that it will run normally. <trac>7356</trac>

Step 4: Update activities

After you reboot the first time, sugar should notify you that your activities should be updated. Your activity update process will differ depending on whether or not you have network access.

G1G1 Activity install

Activities update proposal

With the XO connected to the internet

First, connect to the internet, and then either click the "Check now" icon in the update notification dialog, or, if you've dismissed the dialog, open the sugar control panel and click the "Software update" module.

You should see a progress bar as your XO looks for the appropriate updated versions of the activities you have installed. When it is done, click "Install selected" to update your activities. You'll see another progress bar, as the activities are updated.

Some activities may not successfully update, either because the new version of the activity is improperly packaged or due to transient network errors. If this is the case, some activities will remain in the "available updates" list after the installation process has completed. If a network error was the cause, you may wish to immediately retry the installation; otherwise, you probably need to wait until the activity author uploads a corrected version of their bundle.

Without the XO connected to the internet

If you do not have a connection to the internet:

1. Download the G1G1 Activity Pack (from here) and unzip it in the base (root) directory of a BLANK USB flash drive. You should see two directories (boot and bundles), and a file called customization-2 in the base directory.

 /boot
 /bundles
 customization-2

2. Insert the USB flash drive and reboot the XO. It will display text on a black screen as the activities are installed, after which it will power off.

3. Remove the USB flash drive.

Notes

• The USB flash drive should be formatted with a VFAT file system (FAT16 with long filename support); this is the common format for most USB sticks with capacity up to 2 GB.
  • It is important that the USB flash drive have a partition table, and that the VFAT file system be in the first partition. Linux allows you to put a file system directly on the drive itself without a partition table (i.e. "mkfs.vfat /dev/sdi", rather than fdisk and "mkfs.vfat /dev/sdi1"), but then on boot, the XO will panic with an error from mount ("non-zero status code 255").
• You can perform steps 1 and 2 on another computer, or if you are familiar with the Linux command line, on the XO in a terminal using wget and unzip.
• Commands such as "extract here" in ubuntu / windows will sometimes create a directory with the same name as the zip file, placing the unzipped files within it. If this happens, you will have to move the files to the base directory in order for your XO to see them on boot.
• The "boot" directory will contain two zip files, actos.zip and runos.zip. This is normal; these files SHOULD NOT be unzipped.
• Warning: the USB flash drive should be empty before this operation to contain ONLY the G1G1 Activity Pack files at end.
• If your machine is not a secure XO (its firmware is unlocked), you must boot in secure mode. If you have a developer key on a removable media like an SD card or a USB key, remove the media. If the developer key is on the NAND FLASH or the machine is permanently unlocked, hold the X game key while booting.

In addition to the G1G1 activity pack, some commonly installed alternative activity packs include the:

• Peru activity pack
• Nepal activity pack
• ...more activity packs

(The Nepal activity pack contains some additional customizations made by OLE Nepal for their pilot).

To install these packs, use the same process that you just used to install the G1G1 activity pack.
