Builds

Nearly all the software for the OLPC is open source, so in theory you could acquire the latest versions of all the needed source code together with the tools to compile it, and produce your own software.

In practice, centralized procedures regularly assemble the needed software elements in a build that developers and advanced users can install and test. The OS images page has more details on this nightly process.

Some well-known builds are made widely available as official releases, either as an unscheduled release (also known as a "patch" or ECO), or as one of the planned releases on the roadmap.

Build names and branches

Ship.1 is build 623, and was preloaded on all mass production XO machines for a while.

It isn't preloaded on new machines, and any machine with it installed should since have been updated to Ship.2. It was released around 2007-11-01. It will mostly not be seen by the outside world at all.

Ship.2 is build 650

It is the build received by Give One Get One recipients, as well as the Uruguay Ceibal project users. (Actually, Uruguay is using a slightly custom build, but it's based on Ship.2.) It was released around 2007-12-01. Read the OLPC Ship.2 Software Release Notes.

OLPC 8.1.0 (Update.1) is build 703

OLPC SW-ECO 4 - This release contains no activities, and is suitable for a base image to be customized by deploying countries using a Customization key. Release notes are available. Machines can be automatically upgraded (preserving user data) from Ship.2 to 8.1.0, although activities need to be reinstalled as they are no longer contained in the image - see the release notes.

OLPC 8.1.1 will be released in June 2008 as a minor update to 8.1.0. The current release candidate is build 708.

OLPC SW-ECO 5 - Release notes are available.

OLPC 8.2.0 is planned to be released in August 2008, current Joyride builds are progress towards it.

(No ECO yet)

Joyride builds are available at http://xs-dev.laptop.org/~cscott/olpc/streams/joyride/

"Joyride" can be thought of as synonymous with "trunk" or "HEAD" or "unstable", much like the Debian/unstable distribution.

The Releases page and http://dev.laptop.org/roadmap enumerate releases beyond 8.2.0.
