Upgrade and Compatibility Information

This section lists changes which could affect user applications developed using older SDK versions. Read this carefully to see if you need to do any changes in your existing application when migrating to this SDK version relative to previous SDK version. Also refer to older SDK version release notes to see changes in earlier SDKs.

The below table captures the list of migration document sections when migrating from one version to another. The migration for a partcluar module will be applicable, if you are migrating from older version listed to newer version listed on the table below.
