Detailed Changelogs for Beta Testing?

Hi all. I'm interested in participating some more in the beta program, and more generally in understanding the roadmap.

I see that the latest beta release is 4.45.0, and the version on the Apple App Store is 4.44.3

4.45.0 looks very similar to 4.44.3, which I just installed over. The changelog describes "photo logging updates, apple health and health connect fixes". Which is cool and all. But I don't really know how to test those.

Is the photo logging meant to be more… accurate? Was the under-the-hood prompting modified? If I chose to switch to Apple Health for my activity expenditure over Garmin to test this, what am I looking for? What should be broken?

Further, 4.42.0 says something about Voice Logging. Which sounds like something that'd need testing. But it doesn't exist in the latest build. I'm guessing it's a separate branch, and the beta releases have to go sequentially to install on top of the current release?

Anyway, I guess my feedback here is that detailed release notes/changelogs would be helpful, as a tester. If they exist, please point me in the right direction
