= Steps to Take Before Upgrading to this Release =
== Before you update to this release==
* If you are in a school or other Deployment, make sure you contact your technical support team before upgrading. Some deployments have special configurations which will need special steps taken before upgrading or may not be able to upgrade at all.
* 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.


== New features in 8.2.0 ==
* Determine which release you are on and whether you plan to upgrade over the Internet or via USB stick. Then, choose an upgrade method from the available [[Release_Notes/8.2.0#Upgrading_from_Previous_Releases|upgrade options]].


There is a new Help Activity in this release that includes a full manual on the laptop. Look for the icon of a Question Mark.
* Determine the version of your activities. Decide if you need to re-install or upgrade them and make sure you have access those them. See the list of [[Release_Notes/8.2.0#Activities_Needing_Upgrade|activities you must upgrade]], and go [[Release_Notes/8.2.0#Upgrading_from_Previous_Releases|here]] for instructions on how to reinstall all activities.


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

== GUI and Usability Improvements ==


== Upgrading from previous releases ==
=== Home View Redesign ===
====Home View====


For technical details and other upgrade options see [[olpc-update]] and [[Clean-install procedure]]. If you run into trouble, see [[Upgrade troubleshooting]], [[Support FAQ]] and [[Support]] to email our tech support volunteers.
There are now three distinct view options in the Home zoom level.


=== If your XO is connected to the internet ===

Image:Home List View8.2.png|'''Home List view'''
</gallery>


'''Note that this process may make some of your Activities and the Journal items that depend on them not work - make sure you have backed up any files you want to save!'''
;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.


This process can take more than 30 minutes, much longer if you have a slow internet connection.
====Launching activities====


# Make sure your XO is plugged in, turned on, and [http://laptop.org/manual/XO_GiveMeTheInternet.html connected to the Internet] (you should be able to load http://laptop.org in the Browse Activity). If your XO is not connected to the internet, you will not be able to use this upgrade method.
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.)
# Open the Terminal Activity. [[Image:Activity-terminal.svg]] You can find it by going to the home view (press the 5th symbol from the left, top row), clicking on the little arrow at the bottom right of the screen, and then on the symbol that looks like this one.

# In the Terminal Activity, type <code>su -</code> (lowercase letter 's', lowercase letter 'u', a space, and a hyphen). Press Enter.
====Removing activities====
# At the <code>"-bash-3.2#"</code> prompt type <code>olpc-update 767</code>. Press Enter.

# You should see text that looks something like this (sometimes, in addition to the text below, you might get a message about irsync_pristine failing, and that "irsync_dirty" is being tried, this is normal):
[[Image:Removing Activities8.2.0.png|thumb|right|Activities can be individually erased to free up space for new Activity course material]]
<pre>
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.
Downloading contents of build ''{{:Friends in testing/current image}}''

Updating to version hash ''xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx''
=== Frame Redesign ===
Making clean /versions/updates/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
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.
Trying irsync_pristine update from rsync://updates.laptop.org/''build-{{:Friends in testing/current image}}''

[[Image:Frame-01.jpeg|thumb|right|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 now appears in the bottom edge of the Frame, where its readily available. 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.

=== Updated Journal ===

The new software includes an updated Journal as well, which closely resembles the old one, but has a cleaner look and some additional features 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.

====Getting more details====

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 on the home view XO icon, the control panel currently provides a graphical interface for setting the below options. More detailed instructions can be found [http://wiki.laptop.org/go/Sugar_Control_Panel#The_graphical_user_interface here].

* Technical details at <trac>7380</trac>

== Longer Battery Life ==
This feature is implemented via the Sugar Control Panel. It is off by default so you must enable it in the Sugar Control Panel, power section 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 active processes are running 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. Power saving mode would be turned on when Battery will last longer by dimming the screen and turning off the CPU when the user doesn't touch the touchpad.

* Extreme power management
This mode is the same as above with the addition that it turns off the wireless radio. Once this mode is turned on the XO wireless network connection will disconnect. This is the most agressive power saving mode available and will give the longest battery life.

Details on the software implementation at <trac>7384</trac>

== Improved Launching of Activities ==

* New activity launching feedback
** Strong and clear visual feedback that an activity is starting-up
** Reduces chance that other activities will be accidentally started while the first is still loading
* Launch speed improvement (details tbd)

== Improved Cursor Control (not confirmed) ==
It is better but if you still experience problems where the cursor moves unexpectedly, the touchpad may be trying to recalibrate. It cannot recalibrate accurately while you are touching it. So taking your finger off the touchpad for 10 seconds may help solve problems of unexpected cursor movement.

== Collaboration Improvements ==

== New OS (Fedora 9) Improves Security & Supports More Devices ==
Better security than Fedora 7

=== More external device support (needs edit & support confirmation) ===

We are upgrading from v2.6.22 to v2.6.25.
These pages document most of the new hardware support (and other kernel
features): <br>
http://kernelnewbies.org/Linux_2_6_23 <br>
http://kernelnewbies.org/Linux_2_6_24 <br>
http://kernelnewbies.org/Linux_2_6_25 <br>
Much of the new hardware support won't be relevant for us - e.g. all of
the internal hardware support (I don't think we have users adding
hardware on the inside!). Also some of the external hardware support
will be irrelevant too, e.g. we probably don't have any software that could operate a USB TV tuner.

Master trac ID: <trac>7383</trac>

=== Improved Flash compatibility ===

OLPC ships [http://www.gnu.org/software/gnash/ Gnash], an open source flash movie player integrated into the Browse activity. This release includes an automatic update from Gnash-0.8.1 to Gnash-0.8.3.

The newer version of Gnash increases compatibility with many sites. For example, [http://www.pbskids.com/caillou Caillou] animation rendering was incorrect in previous releases, but now appears to work correctly.

= Upgrading from Previous Releases =

Before upgrading, you should know that upgrading is a very strict and a very important process. So you should be sure to read and carefully follow these instructions and be sure to have enough time to do the full process before you begin.

'''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 [http://wiki.laptop.org/go/Upgrading_the_XO#Overview_of_Upgrading_Options upgrade instructions].

Here are the steps to upgrade:
# Plug the XO into AC Power
# Connect XO to the internet
# Launch the update command
# Reinstall the activities


'''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.

'''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 [[Wifi Connectivity]] for instructions. Use Browse activity to test your connection.

'''Launch the update command'''. Open the '''[[Terminal Activity]]''' [[Image:Activity-terminal.svg|35px]] and type the following (press the Enter key after each line):

[[su -l]]
olpc-update ''build-number'' <!-- reboot, verbose -->

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

Downloading contents of build ''build-number''
Updating to version hash ''xxxx''
Making clean /versions/updates/...
Trying irsync_pristine update from rsync://updates.laptop.org/build-''build-number''
- Cleaning tree.
- Cleaning tree.
- Fetching contents.
- Fetching contents.
- Performing incremental rsync.
- Performing incremental rsync. [Comment: Wait a long time! Could be over an hour depending on your internet connection speed.]
Verifying update.
Verifying update.
Installing update in /versions/{pristine,run}/''xxxx''
Installing update in /versions/{pristine,run}/''xxxx''
</pre>
6. At the end of the upgrade, you will either see the words "Installing update in...." or "Update Succeeded!" on the screen. If you see the words "I don't think you're connected to the internet." see the notes below. <br>
<br>
7. Wait for the prompt <code>"-bash-3.2#"</code> and type <code>reboot</code> then press Enter to restart your XO. You will probably hear the little XO tune 2 times, then it will say erasing and a countdown will appear. Finally it will reboot again, you will hear the tune for a third time. Now you are ready to go to step 8.<br>
<br>
8. After your XO reboots, the last step is to download the new versions of Activities. When the XO boots you will see a bar toward the top of the screen that says "Software Update" and the options being "Cancel", "Later" and "Check now". Before you choose "Check now" to update the activities, you must reconnect your XO to the internet. You may see the sign-in box appear in home view. If it does, and it lists your router, you can do it from there. If it doesn't appear or offers the wrong connection, go to the Neighborhood view and connect from there. Then go back to Home view and then click "Check now" (it's ok to leave the home view because when you go back the options should still be there). First the XO will check for any updates and then it asks if you'd like to install them. Click "Install selected" to install your newest versions of your activities. <br>


Congratulations, you've upgraded!
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>

For release notes on all previous releases see [[Release Notes]]

To determine which release you currently have on your XO, see: <br>
[[How_to_check_the_OS_and_firmware_versions]]

== Reinstall activities ==
Starting from build 699, the [[OS Images|OS image]] is separate from the activities.

'''Important Note: This means that if you are upgrading from a build prior to 700, such as the original G1G1 "Ship.1" software, you will lose all you existing activities!''' If you are upgrading from any release after build 699 such as "Update.1" or 8.1.0, the build is already separated from the activities and you will not lose your existing activities.

To re-install the activities after upgrading, follow these instructions:
# Download the [[G1G1 Activity Pack]] (from [http://wiki.laptop.org/images/6/62/G1G1_Activity_Pack_1.zip here]) and unzip it in the base (root) directory of a USB flash drive. You should see two directories (boot and bundles, and a file called customization-2) in the base directory. 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. (Note that 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.
# Plug the XO into AC power and connect it to the internet.
# In a console, run [[olpc-update]] to the new build. ( [[Terminal Activity|terminal]] -> <tt>su -l</tt> (lowercase L, not 1) -> <tt>olpc-update -fvv candidate-708</tt> ) This may take half an hour or more, depending on your internet connection.
# 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.
# Remove the USB flash drive. Connect the XO to AC power, so that it will be able to proceed if it determines that a firmware update is needed. Then power on your XO as per usual.

Some commonly installed activity packs include the:

* [[G1G1 activity pack]] ([[Media:G1G1 Activity Pack 1.zip|download]])
* [[Peru activity pack]]
* [[Nepal:_Testing%2C_QA%2C_and_Configuration#Nepal_Activity_Pack|Nepal activity pack]]
* [[:Category:Activity Pack|...more activity packs]]


'''Note:'''
(The Nepal activity pack contains some [[Nepal_Customization_702|additional customizations]] made by [[OLE Nepal]] for their pilot).
* When upgrading from build 703 or 708 you will not see the Library (links to science, books, etc links on the left side) in the Browse home page. You can re-install the Library as follows:
** Open the Control Panel and go into Software update.
** After it checks for updates, go to <code>"Modify activity groups"</code> and click on the triangle.
** Beside <code>"Group URL"</code> type: <code> http://wiki.laptop.org/go/Activities/G1G1 </code> and click the <code>"Add"</code> button.
** Click <code>"Refresh"</code> and allow the XO to upload the new updates.
** Click on Install selected. Once it completes, reboot.
* If you can browse the Internet (see step 1 above) but the <tt>olpc-update</tt> command returns the error <code>"I don't think you're connected to the internet."</code>, you may need to open TCP port 873 (rsync) on your firewall for the outbound connection.


=== Offline upgrade ===
'''TO INSTALL AN ACTIVITY PACK:'''
[[Image:YamaDone.JPG|thumb|''for new users'' [[USB_upgrade|<br>'''illustrated guide to upgrading using a USB stick<br>''']]]]
{{:Install an activity pack}}
You can use another computer that is connected to the internet (a desktop at home, a computer lab, etc.) plus a USB storage device (such as a compatible [[USB_drive#USB_drives_and_firmware|USB flash drive]]) to upgrade your XO.
The way it works is on your non-XO computer you download two files containing the upgrade data, saving them to the USB flash drive; then you insert the USB flash drive into your XO and trigger its upgrade process.
'''Note that this process will COMPLETELY erase ALL files on your XO! Make sure you have backed up any files you want to save!'''


Plug an empty formatted USB flash drive into the computer that is connected to the internet.

* Record-54 (and older versions) will fail to take photos and record videos, upgrade to Record-55.
* Browse-91 (and older versions) will fail to download files and install .xo/.xol bundles. Upgrade to Browse-92.
* Implode-3 (and older versions) will fail to launch, upgrade to Implode-4.


The first file is about 297 KB, and the second file is quite large (about 450 MB), so they might take a while [15 - 20 min.] to download. When the download is complete, Eject/Remove the USB flash drive, and unplug it. After you have finished this step, there should be two files on the USB flash drive, the <tt>fs.zip file</tt>, and the <tt>.img</tt> file. The MD5 checksum for fs.zip is 1bb452e77b7390e00bdd7fdcc7cbc793 The MD5 checksum for gg-767-4.img is 3f281dda352d32320879728377b32476

# Make sure your XO is plugged in.
# Hold down all four gamepad keys (on the right side of the screen, above the power button). While still holding the four gamepad keys, push the power button to turn the XO on. Keep holding down the four gamepad keys until the message "Release the game key to continue" appears on the screen.
# Release the gamepad keys. If you see a grid of colored boxes on your screen, congratulations! Your XO is reflashing. It will take about 10 minutes and your XO will automatically reboot when it is done. Your XO may reboot twice, playing the little XO tune.
# After your XO reboots, the last step is to update to the newest versions of Activities. When the XO boots you will see a bar toward the top of the screen that says "Software Update" and the options being "Cancel", "Later" and "Check now". Before you choose "Check now" to update the activities, you must reconnect your XO to the internet. You may see the sign-in box appear in home view. If it does, and it lists your router, you can do it from there. If it doesn't appear or offers the wrong connection, go to the Neighborhood view and connect from there. Then go back to Home view and then click "Check now" (it's ok to leave the home view because when you go back the options should still be there). First the XO will check for any updates and then it asks if you'd like to install them. Click "Install selected" to install the newest versions of your activities. <br>
Congratulations, you've upgraded!
Now, you should be ready to go. Have fun!

For the best experience and maximum reliability with the XO we recommend the following best practices:
== Network Related Issues ==
There are many open mesh and collaboration bugs.


'''For all XOs'''
Work is being done in that area in this release but it is not confirmed yet.
* If you open too many activities (generally more than 3) at once you may experience slow response. To close activities, use the frame button (upper right), hover over the open activities, and click on close.
* In general, you do not need to double click on anything in the XO interface. It is designed for a single click. For example, double clicking to launch an activity will cause the XO to launch two instances of the activity which may cause one to fail.
* Drag and drop has limited support in this release. It may work in some cases but it does not work consistently everywhere.
* Power save mode is still in development. In this release it is turned off by default in the control panel. If you use it and experience problems, please turn it off.
* If the XO stops collaborating or stops responding, you can reboot it from the home screen (hover over the XO in the center) or hold down the power button for more than 6 seconds.
* Ensure that you have unmounted a USB stick before removing it. Go to the Journal, hover over the USB stick icon and click on 'unmount'. Another method to remove a USB stick and avoid corruption is to power down the laptop before removing the USB stick..

* Reliable collaboration using the Write activity over mesh or access point networks may not exceed two hours. If there are a lot of XOs or a lot of wireless traffic (e.g. many XOs or many access points) then Write may shut down during collaboration. In this case you may be able to reconnect Write to the collaboration in the Neighborhood view.
This is a list of short cuts and tricks for power users of the XO.
* When collaborating over a Mesh (i.e. XO to XO collaboration with no access point or school server) you should limit the number of XOs on any channel to 10. There are three Mesh channels available (1,6 and 11) and each should have a maximum of 10 XOs. More XOs in a channel may cause instability in the collaboration.


These are not all tested and confirmed working in all circumstances so please use with caution.


* Please see the [[Deployment Support]] pages for information on collaboration and connectivity in schools or areas that are densely populated with XOs.

  For the general public

Our apologies, but if you are using Browse in version 10.1.1 on XO-1.5 you may have been directed to this page by mistake. If so, please go to the 10.1.1 release notes. The rest of this page relates to version 8.2.0.

Before you update to this release

  • 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.

New features in 8.2.0

There is a new Help Activity in this release that includes a full manual on the laptop. Look for the icon of a Question Mark.

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

The new XO manual for release 8.2.0 is available here.

Upgrading from previous releases

For technical details and other upgrade options see olpc-update and Clean-install procedure. If you run into trouble, see Upgrade troubleshooting, Support FAQ and Support to email our tech support volunteers.

If your XO is connected to the internet

Note that this process may make some of your Activities and the Journal items that depend on them not work - make sure you have backed up any files you want to save!

This process can take more than 30 minutes, much longer if you have a slow internet connection.

  1. Make sure your XO is plugged in, turned on, and connected to the Internet (you should be able to load http://laptop.org in the Browse Activity). If your XO is not connected to the internet, you will not be able to use this upgrade method.
  2. Open the Terminal Activity. Activity-terminal.svg You can find it by going to the home view (press the 5th symbol from the left, top row), clicking on the little arrow at the bottom right of the screen, and then on the symbol that looks like this one.
  3. In the Terminal Activity, type su - (lowercase letter 's', lowercase letter 'u', a space, and a hyphen). Press Enter.
  4. At the "-bash-3.2#" prompt type olpc-update 767. Press Enter.
  5. You should see text that looks something like this (sometimes, in addition to the text below, you might get a message about irsync_pristine failing, and that "irsync_dirty" is being tried, this is normal):
 Downloading contents of build ''{{:Friends in testing/current image}}''
 Updating to version hash ''xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx''
 Making clean /versions/updates/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
 Trying irsync_pristine update from rsync://updates.laptop.org/''build-{{:Friends in testing/current image}}''
 - Cleaning tree.
 - Fetching contents.
 - Performing incremental rsync. [Comment: Wait a long time! Could be over an hour depending on your internet connection speed.]
 Verifying update.
 Installing update in /versions/{pristine,run}/''xxxx''

6. At the end of the upgrade, you will either see the words "Installing update in...." or "Update Succeeded!" on the screen. If you see the words "I don't think you're connected to the internet." see the notes below.

7. Wait for the prompt "-bash-3.2#" and type reboot then press Enter to restart your XO. You will probably hear the little XO tune 2 times, then it will say erasing and a countdown will appear. Finally it will reboot again, you will hear the tune for a third time. Now you are ready to go to step 8.

8. After your XO reboots, the last step is to download the new versions of Activities. When the XO boots you will see a bar toward the top of the screen that says "Software Update" and the options being "Cancel", "Later" and "Check now". Before you choose "Check now" to update the activities, you must reconnect your XO to the internet. You may see the sign-in box appear in home view. If it does, and it lists your router, you can do it from there. If it doesn't appear or offers the wrong connection, go to the Neighborhood view and connect from there. Then go back to Home view and then click "Check now" (it's ok to leave the home view because when you go back the options should still be there). First the XO will check for any updates and then it asks if you'd like to install them. Click "Install selected" to install your newest versions of your activities.

Congratulations, you've upgraded!

Note:

  • When upgrading from build 703 or 708 you will not see the Library (links to science, books, etc links on the left side) in the Browse home page. You can re-install the Library as follows:
    • Open the Control Panel and go into Software update.
    • After it checks for updates, go to "Modify activity groups" and click on the triangle.
    • Beside "Group URL" type: http://wiki.laptop.org/go/Activities/G1G1 and click the "Add" button.
    • Click "Refresh" and allow the XO to upload the new updates.
    • Click on Install selected. Once it completes, reboot.
  • If you can browse the Internet (see step 1 above) but the olpc-update command returns the error "I don't think you're connected to the internet.", you may need to open TCP port 873 (rsync) on your firewall for the outbound connection.

Offline upgrade

You can use another computer that is connected to the internet (a desktop at home, a computer lab, etc.) plus a USB storage device (such as a compatible USB flash drive) to upgrade your XO. The way it works is on your non-XO computer you download two files containing the upgrade data, saving them to the USB flash drive; then you insert the USB flash drive into your XO and trigger its upgrade process. Note that this process will COMPLETELY erase ALL files on your XO! Make sure you have backed up any files you want to save!

Plug an empty formatted USB flash drive into the computer that is connected to the internet. Then, right-click (Ctrl-click for Mac) on each of the two URLs below and choose "Save Target As" ("Save Link As" for Firefox). Save both files to the USB flash drive. Do not open the files.

The first file is about 297 KB, and the second file is quite large (about 450 MB), so they might take a while [15 - 20 min.] to download. When the download is complete, Eject/Remove the USB flash drive, and unplug it. After you have finished this step, there should be two files on the USB flash drive, the fs.zip file, and the .img file. The MD5 checksum for fs.zip is 1bb452e77b7390e00bdd7fdcc7cbc793 The MD5 checksum for gg-767-4.img is 3f281dda352d32320879728377b32476

Now, follow the steps below to complete your installation:

  1. Turn off your XO and connect your USB flash drive to it.
  2. Make sure your XO is plugged in.
  3. Hold down all four gamepad keys (on the right side of the screen, above the power button). While still holding the four gamepad keys, push the power button to turn the XO on. Keep holding down the four gamepad keys until the message "Release the game key to continue" appears on the screen.
  4. Release the gamepad keys. If you see a grid of colored boxes on your screen, congratulations! Your XO is reflashing. It will take about 10 minutes and your XO will automatically reboot when it is done. Your XO may reboot twice, playing the little XO tune.
  5. After your XO reboots, the last step is to update to the newest versions of Activities. When the XO boots you will see a bar toward the top of the screen that says "Software Update" and the options being "Cancel", "Later" and "Check now". Before you choose "Check now" to update the activities, you must reconnect your XO to the internet. You may see the sign-in box appear in home view. If it does, and it lists your router, you can do it from there. If it doesn't appear or offers the wrong connection, go to the Neighborhood view and connect from there. Then go back to Home view and then click "Check now" (it's ok to leave the home view because when you go back the options should still be there). First the XO will check for any updates and then it asks if you'd like to install them. Click "Install selected" to install the newest versions of your activities.

Congratulations, you've upgraded! Now, you should be ready to go. Have fun!

(If you chose "Later" on the software update, go to the Sugar Control Panel and select the "Software update" when you are ready to install the updates)

Resolved bugs in this release

Many bugs were closed in this release. A few important ones include:
<trac>5156</trac> Browse can view Google calendar.

<trac>5613</trac> The XO name can now accept any characters. This is important for languages which do not use the ASCII characters.

<trac>6014</trac> Activities try to save their data when the XO is shut down while an activity is open. This is better but not complete. Users should close their activities before shutting down the XO.

<trac>7480</trac> You can reset your network history in the Network control panel in case you need to remove old configurations. However, you will need to re-enter all AP passwords after doing this.

For the best experience and maximum reliability with the XO we recommend the following best practices:

For all XOs

  • If you open too many activities (generally more than 3) at once you may experience slow response. To close activities, use the frame button (upper right), hover over the open activities, and click on close.
  • In general, you do not need to double click on anything in the XO interface. It is designed for a single click. For example, double clicking to launch an activity will cause the XO to launch two instances of the activity which may cause one to fail.
  • Drag and drop has limited support in this release. It may work in some cases but it does not work consistently everywhere.
  • Power save mode is still in development. In this release it is turned off by default in the control panel. If you use it and experience problems, please turn it off.
  • If the XO stops collaborating or stops responding, you can reboot it from the home screen (hover over the XO in the center) or hold down the power button for more than 6 seconds.
  • Ensure that you have unmounted a USB stick before removing it. Go to the Journal, hover over the USB stick icon and click on 'unmount'. Another method to remove a USB stick and avoid corruption is to power down the laptop before removing the USB stick..

For XOs used in school with many XOs present

  • Reliable collaboration using the Write activity over mesh or access point networks may not exceed two hours. If there are a lot of XOs or a lot of wireless traffic (e.g. many XOs or many access points) then Write may shut down during collaboration. In this case you may be able to reconnect Write to the collaboration in the Neighborhood view.
  • When collaborating over a Mesh (i.e. XO to XO collaboration with no access point or school server) you should limit the number of XOs on any channel to 10. There are three Mesh channels available (1,6 and 11) and each should have a maximum of 10 XOs. More XOs in a channel may cause instability in the collaboration.
