Summary

This cumulative update package for Microsoft BizTalk Server 2020 contains hotfixes for the BizTalk Server 2020 issues that were fixed after the release of BizTalk Server 2020.

We recommend that you test hotfixes before you deploy them in a production environment. Because the builds are cumulative, each new update release contains all the hotfixes and all the security updates that were included in the previous BizTalk Server 2020 update release. We recommend that you consider applying the most recent BizTalk Server 2020 update release.

Important information about the cumulative update package

Each cumulative hotfix package includes all the component packages. However, a cumulative update package updates only those components that are installed on the system.

Note For more information about the latest service pack or cumulative update package for BizTalk Server, see the following article in the Microsoft Knowledge Base:

2555976 Service Pack and cumulative update list for BizTalk Server

Note If you use the MQSeries adapter, MQSAgent.dll must be updated on the IBM WebSphere MQ server to the same cumulative update level that's on BizTalk Server. To do this, make sure that you run the same cumulative update setup on the IBM WebSphere MQ server. You may experience performance issues if you run mismatched versions.

This cumulative update package is a rollup update that contains the following items:

How to get Cumulative Update Package 5 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 test and then apply the latest CU to all BizTalk environments.

All new fixes are publicly released in the upcoming CU. Standalone fixes might 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.
