How to obtain cumulative update package 4 for BizTalk Server 2013

BizTalk Server uses a cumulative update (CU) model for providing fixes and updates. Each cumulative update includes new updates as well as all of the updates included in the previous cumulative updates. Microsoft recommends testing and then applying the latest CU to all BizTalk environments.

All new fixes are publicly released in the upcoming cumulative update. Stand-alone fixes may be provided prior to the next cumulative update if the reported problem is critical, has significant business impact, and does not have a workaround. Stand-alone fixes (if provided) require the latest released cumulative update as a prerequisite.
