This release is not yet complete. These notes are draft, and User:Quozl has taken responsibility for ensuring they are ready for a release should a release occur.
The purpose of our release notes is to describe the release after it happens, explain how to install it, list what the known problems are, and what was changed.
Prior to the release this page may serve testers as a guide to the installation of unsigned development build, as an indicator of what known problems we do not expect to fix in this release, and the bugs fixed so far.
Please do not re-announce this page as a release.
Purpose
An update to software release 10.1.1 for both XO-1 and XO-1.5 laptops.

- Save the file to the top directory of the USB drive,
- Download os850.zsp.fs.zip,
- Save the file to the top directory of the same USB drive,
- Rename the file to fs.zip, (removing the os850.zsp part of the name),
- Check the USB drive contains at least the two files fs.zip and os850.zd.
- Prepare the laptop:
- Make a copy of any data you wish to keep,
- Check the battery is inserted and locked,
- Check that the power cord is in place and the battery indicator is green,

Upgrade
You may wish to upgrade from a previous version of the XO-1.5 operating system. This method preserves most user data, Sugar journal and installed Sugar activities, but does not preserve certain operating system customisations such as additional packages.
Since activities are not updated, several known problems will remain. Most but not all of these can be fixed using Software update.
To use this method, establish an internet connection, and launch the Terminal Activity.
For XO-1, then type:
olpc-update 10.1.2_xo1-850
For XO-1.5, then type:
olpc-update 10.1.2_xo1.5-850
A few previous versions do not support this method.
New features
to be completed
Known Problems
XO-1.0 Greek language
In list with all languages there isn't the Greek language to change the environment into it.
XO-1.5 No screen rotation
The screen rotation key (on the bottom left of the display) does not rotate the screen image. It is safe to use, but makes no change.
Developers are working on rotation support in the graphics driver. (<trac>9350</trac>)
Record activity video recording may pause
When recording a video of a very complex natural scene, such as moving vegetation, the recording may pause. If this happens, reducing camera movement may allow the laptop to catch up. The pause is visible on playback.
On XO-1.5, switch to Low quality and try again. XO-1 only has Low quality.
In the previous release 8.2.1, the pause was spread throughout the recording, lowering the effective frame rate. In this release the frame rate is kept as fast as possible until the pause is unavoidable.
XO-1.5 Record activity preview black on lid close and open
With the Record activity on screen displaying a preview of the camera image, closing the laptop lid for long enough to cause a suspend, and then opening it, results in the preview going black.
If this happens, the preview can be restored by pressing Alt/Tab, or switching between Sugar views using the keyboard keys or the frame icons.
The black preview does not affect the taking of photographs, or recording of video. If a video recording is being made, there will be a segment of time missing in the playback.
Developers are aware of the problem. (<trac>10068</trac>)
