VisualAge Smalltalk Server, the runtime environment for deploying server applications, is now included with VisualAge Smalltalk Server Workbench. This means that all of the code required to deploy server applications is included as part of Server Workbench and it is no longer necessary to install this feature separately.
The deployment environment for Server Workbench is not backward compatible with Server 5.0 or 4.5. This means that applications packaged on Server Workbench 4.5 or Server Workbench 5.0 will not run on the redistributable files for Server Workbench 5.0. To enable your 5.0 or 4.5 application to run on a Version 5.5 system, repackage your application using Server Workbench Version 5.5.
If your systems need to run applications packaged from both releases, keep Server Runtime 4.5 or 5.0 installed in parallel with Server Runtime 5.5 on those systems.
