Migrating API Gateways: Autodiscovery
|
Standard Support for Mule 4.1 ended on November 2, 2020, and this version of Mule reached its End of Life on November 2, 2022, when Extended Support ended. Deployments of new applications to CloudHub that use this version of Mule are no longer allowed. Only in-place updates to applications are permitted. MuleSoft recommends that you upgrade to the latest version of Mule 4 that is in Standard Support so that your applications run with the latest fixes and security enhancements. |
The Autodiscovery element was updated after Mule 4 release.
-
APIs are referenced by an ID instead of a name and version.
-
Creation of APIs from the runtime is no longer possible.
