Eclipse 3.4 includes a completely new provisioning system dubbed p2. This system is a complete rewrite of the Update Manager found in previous releases of the platform. For the most part, plug-in developers need not be concerned about the details of p2. You continue to author plug-ins, features, and update sites as before. However, there are some steps you can take to optimize your applications and update sites for use by p2, and there are some tools available for managing p2 code repositories. Details on how to use these tools can be found in this section.
