The focus of this build is stability and usability in a classroom environment. While there wasn't
[[Image:Dextrose_main.png|640px|frameless|right]]
much time for new development, we've merged a few features contributed by other deployments and
freelance contributors:


* Journal sorting options (aa)
== The deployments' XO Operating System ==
* CPU/Memory display (m_anish)
* Journal Backup/restore to removable devices (tch, esteban)
* Journal Backup/restore to schoolserver (tch)
* Protected activities support (tch)
* Improved GSM/3G handling (tch, dcastelo)
* Tabbed browsing (m_anish)
* Accessibility features (esteban)
* Journal repair functionality (esteban)
* Fast switching between touchpad and pen-tablet modes (wbender)
* OLPC Microformat support in activity updater (gangil) (pending)

=== XO-1 ===
== Dextrose 2 - World Edition ==


* First, ensure that your laptop is [http://wiki.laptop.org/go/Activation_and_developer_keys unlocked].
[[File:Download-dextrose-py.png]]
* Download <tt>osNNNpy.img</tt> and <tt>osNNNpy.crc</tt> to the root directory of a USB stick
* Drop to the "ok" prompt by pressing ESC repetedly during boot
* Type the command: <code>copy-nand u:\osNNNpy.img</code> followed by ENTER
* During the next reboot, keep the charger connected to allow OFW to self-update


Also check these [http://wiki.laptop.org/go/F11_for_XO-1#Installation_instructions detailed instructions].
'''This is a release build''' targeted for use by multiple deployments worldwide. We do appreciate [[Dextrose/Contacts|feedback]] and [http://bugs.sugarlabs.org/wiki/Dextrose bug reports].
 
=== XO-1.5 ===
 
* Download <tt>osNNNpy.zd</tt> to the root directory of a USB stick
* Drop to the "ok" prompt by pressing ESC repetedly during boot
* Type the command: <code>fs-update u:\osNNNpy.zd</code> followed by ENTER
 
Also check these [http://wiki.laptop.org/go/F11_for_1.5 detailed instructions].
 
 
== Testing ==
 
Besides community testing and field testing, we're planning to reuse and extend the
OLPC test plan adopted in release 8.2.0 (aka os801): http://wiki.laptop.org/go/TestPlan_8.2.0
 
Feedback from the entire community is appreciated. Bugs belonging to upstream
components should be filed in the usual trackers:
 
* Sugar and activities: http://bugs.sugarlabs.org/
* Fedora 11: http://bugzilla.redhat.com/
* Drivers and OLPC customizations: http://dev.laptop.org/
* Bugs specific to this build: http://trac.paraguayeduca.org/
 
Please, cc "bernie" on all bugs and kindly keep the table below updated (saves me some time).

A few customizations make this image somewhat deployment-specific:
'''See also''' the  [http://wiki.laptop.org/go/F11_for_1.5 detailed instructions].


* Limited language support: to save space, we've included only English and Spanish translations.
=== XO-1.75 ===


* Image signed with the Paraguay deployment keys. Laptops from other regions need to be unlocked in order to accept this image.
The XO-1.75 is not supported at this time. Please [[Dextrose/Contacts|contact us]] if you are planning to deploy Dextrose on XO-1.75.


* The software update control panel icon checks for new activities on our wiki rather than on laptop.org.
=== Other netbooks ===


* The Browse home page contains the Paraguay Educa logo and a few links to our website.
Please [[Dextrose/Contacts|contact us]] if you need support for running Dextrose on non-XO hardware.


We may find the time to release slightly modified images to meet the
needs of other OLPC deployments interested in upgrading to Sugar 0.88.


More importantly, we're happy to help other deployments produce their
