@neolynx Thanks for your kindly reminds. Updated the patch and make three test cases for it.

Support update "label" and "origin" of aptly publish on:

1. Command aptly publish update
   Add new test case "t06_publish/PublishUpdate19Test"

@neolynx Is there anything else supplementary I need to do? Additionally, is there any possibility of adding this patch to Debian:trixie? One of our projects is built on Debian:trixie, and it would be beneficial to our project if this patch could be added to Debian:trixie.
