General case
The release notes for recent OLPC OS releases include appropriate upgrading instructions. Choose the release you want to upgrade to from the Releases page and view its release notes, or follow the links in the Software box on the right to the latest version, and follow the instructions.
Overview of upgrading options
A more general overview of the upgrading options is presented below.
Online
The XO can be updated with an active internet connection using the olpc-update command.
Offline
The XO can be updated offline from a USB drive for either a simple offline upgrade with olpc-update or the full clean-install procedure. Try these pictorial instructions for beginners!
Revert
You can revert back to the previous version if an update goes wrong if you use the olpc-update method, using the Circle booting procedure on the Cheat codes page. Advanced users will also be able to explicitly opt out in advance of all updates.
Wireless Broadcast
For bulk updates or cloning, XOs may use a wireless broadcast, see Nandblaster.
School server
In school situations, the teacher or administrator would be able to control the update process, perhaps so that updates don't happen until the end of a semester (This functionality is implemented, but the school server tools to actually administer groups of laptops aren't yet ready in early 2008, check School server for more).
Firmware
The OS image includes firmware and so if you upgrade your XO you will also update its firmware if the OS image's firmware is newer. If you'd like to upgrade the firmware separately, see Upgrading firmware.
Opting out of automatic upgrades
For instructions on opting out of the automatic upgrades to your XO's build/firmware, please see the Update streams page.
