The integrated web services (IWS) for i features are frequently enhanced by PTFs. This web page is used to provide a centralized location for communicating integrated web services for i enhancements. The enhancements come in different forms. Some enhancements are made available by PTFs into all or a subset of in-service releases. In other cases, we take enhancements provided in a base OS and PTF the support back to a previous release. In all cases, we use customer value, cost, and risk to guide our decisions regarding off release enhancements. For more information about the integrated web services support on IBM i, visit the product website.

If you would like to see an enhancement in integrated web services support, submit an IBM Idea. Determine whether an idea has not already been created before you submit an idea.

The technology update material has been organized to differentiate between client and server enhancements. Each technology update document will include the HTTP Server Group PTF level the update is included in, unless the enhancement is not in a group PTF, then the actual PTF numbers are shown. It is best to always load the latest levels of the HTTP Server Group PTF in order to pick up the latest enhancements and fixes.
