The i2b2 Upgrades space contains the upgrade documentation and the pre-compiled JAR files that can be used by existing i2b2 sites to upgrade their i2b2 server to the latest version of the i2b2 software. This space is organized as follows:

• Current Upgrade contains the upgrade information for the current release
• Archived Upgrades contains the upgrade information on upgrades for previous releases

As new versions of the i2b2 server are released, the upgrade documentation and the appropriate JAR files will be added to this space.
