The newest release is visually awful. It drove me crazy and I had to downgrade back to the last stable (102). The content density was wildly inconsistent and text would be squished in one area and really spaced out in another. The toolbar moved so action buttons were in the title bar area, away from where your mouse would be (compared to before) if you're interacting with your inbox.

Other than that, the old version works just fine. Multiple email accounts, calendar and contacts. It does the job. Minor nitpicks, like dark mode doesn't dark evwrything, you still have to manually change your reading window colours. But at least it's once and done.
