The i2b2 Upgrades space contains the upgrade documentation and the pre-compiled precompiled 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:

• Upgrading to Current UpgradeRelease contains the upgrade information for the current releasedocumentation and precompiled JAR files to upgrade the i2b2 server to the current released version of the software.
• 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.
