# APIkit for SOAP 1.6.0 Release Notes

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

## January 31, 2025

## What’s New

- In alignment with the release of Mule runtime engine 4.9, APIkit for SOAP 1.6.0 and later drops
  support for the `SoapSdk` and `SoapService` components.

  APIkit for SOAP 1.6.0 and later uses the `SoapClient` component instead of using the `SoapSdk` and
  `SoapService` components so you don’t use components that have known vulnerabilities.
