There’s an official roadmap for Obsidian available here Obsidian Roadmap - Obsidian
But it’s quite frustrating because it’s pretty light and doesn’t get updated so often. You can check through Internet Archive’s Wayback Machine.

Latest fixes and app improvements
I’d be like, “Oh wow, you basically just gave another longer definition of an update”
