First, I don't think all changes require detailed release notes. For example, minor changes like bug fixes. Following up with people who reported the bug is perfect.
However, there are several benefits to providing release notes for more major changes:
Keep customers in the loop
The most obvious reason is keeping your customers updated. Engagement with new features is a process. The bare minimum thing you should do is tell people about the new changes and why they're awesome. Publishing your release notes is huge for increasing feature awareness and adoption.
Keep your team in the loop
If you have a large team, it's hard to keep everyone updated on product changes.
It's especially important for customer-facing teammates to be up to date. Your release notes can be your single source of truth for product changes.
Attract new customers
If your release notes are public, they're a great motivator for potential customers. People want to see that you're actively improving your product.
