Yeah that pretty much describes every big companies release notes. I used to have manual updates in the Google Play store as I enjoyed seeing what was changing. But over time so many companies just started saying things like "Security fixes" and it became a waste of time even bothering to look at them.

And sometimes they do actually add a feature... but they'll mention it within the app itself despite the app updates not mentioning it. Or even more funny is how often I'll see a news article talking about the new feature, but then it never even gets mentioned in the release notes anywhere.
