How to get Cumulative Update Package 4Ā for BizTalk Server

BizTalk Server uses a cumulative update (CU) model for providing fixes and updates. Each CU includes new updates in addition to all the updates that were included in previous CUs. We recommend that you testĀ and then applyĀ the latest CU to all BizTalk environments. All new fixes are publicly released in the upcoming CU. Standalone fixes mightĀ be provided before the next CU if the reported problem is very important, has a significant business effect, and doesn't have a workaround. If standalone fixes are provided, they require that the latest released CU be installed.
