Some of the changes are listed here: https://blog.joinmastodon.org/2024/10/mastodon-4.3/

I had the same experience as you. But now, if you go to preferences, there's an option to disable "advanced web interface". If you uncheck that, you get the simpler view.

Of course, the thing now being called the advanced interface used to just be the default.
