That's great, I'm always happy to see Shattered still chugging along on these older devices.
It's not going to hit for a little while yet, but unfortunately it does look like support for Android 4.3- and then 4.4 may need to go in a future update, perhaps in 2025. The TL;DR is that Google is dropping support for the Dalvik runtime (which was replaced by ART in android 5) in most of their build tools, which means that a lot of code libraries are dropping support in their latest versions.
