Well, sure, maybe bug fixes and improvements at best on top of the pop-up directing you to version 15+ if you want new features going forward.The product pages in the App Store do say that the 14.5 updates include bug fixes and performance improvements. I don't want to believe I just wasted downloading and installing almost 2 GB worth of data just to tell me that a new version is available.
It's the end of the road for new features on that track of the apps.
On the Mac, both subscribers and non-subscribers need the Apple Creator Studio version 15+ now to get any new features going forward, including free ones, or they can keep using version 14.5 and it'll just start to age as-is beyond maybe some bug fixes/security patches over the years.
