Deploy a processor version
After creating a new processor version, you will need to deploy it before you can process documents with this version. Note: You cannot change the deployment status for pretrained processor versions or the current default version.

Change the default processor version
A processor's default version specifies the version that is used to process documents when you don't specify a specific version. When you create a processor, the initial default version is the latest version in the stable channel. If you change the default version, incoming requests are processed using the newly selected version. If you change the default version while the processor is in the middle of a request, the request will continue to use the previously selected version.
