The following table shows the supported Integration SDK versions for each Appian release (starting with the initial release in 19.1). All entries assume you are running the latest hotfix.

• Component plug-ins reference the SDK version in the plug-in manifest
• Connected system plug-ins reference the SDK version in the project's dependency file (for example, build.gradle).
• Our SDKs use the semver standard.
