Hi there.

As a Preliminary Stable Builds user I get updates about once a week.

apt changelog kate-trinity
E: Failed to fetch changelog:/tdebase-trinity.changelog  Changelog 
unavailable for tdebase-trinity=4:14.0.7~pre30-0debian10.0.0+6

Synaptic->(select kate-trinity)-> Get Changelog
This change is not coming from a source that supports changelogs.

URI was:

So being able to examine the git repo to see what changes were made 
looks like the only option.

I may be missing something obvious so apologies in advance if I did.

Where is the git repo?
