SOAP API - missing Build_Update, Build_Delete methods

Hello,

I used SOAP API V4.0 to create my custom synchronization plugin. The aim is to sync our Release/Build repository with the Spira database..

I used Build_Create(..) method to add couple of new builds, but when I want to delete build from Spira database, there is no method available in API documentation. Seems to be one way road then for builds synchronization. Just imagine a case when someone made mistake in build repository and the mistake must be corrected in Spira DB too.

There would be 2 additional methods needed for the plugin:

Is there any solution to go over this problem ???

I checked the release notes for V4.2 and found mysterious remark: "Additional functions added to both the SOAP and REST web service APIs". What thus it mean in real? Is there any documentation to this V4.2 SOAP enhancements or service schema definition? Maybe I will be lucky find these 2 functions there.
