As I said before, I think 18.3 will include some nice improvements and more “minor features”. Potential expansion of the “Default Apps” menu introduced in 18.2. Possibly new Siri Shortcut actions. Some “minor” additions to Apple Intelligence. But as always, what one person deems to be a “minor” improvement, another can find to be a “major” improvement. New Siri Shortcut actions could be very useful. New default app settings could be very useful to some. I think iOS 18.3 will likely bring some new changes, won’t be entirely bug fixes and performance optimizations, but it probably won’t be as big as 18.4. It may still be close to on par with 18.2 though. 👍🏻
