-App is divided into two versions: 1.7 and 1.8 . Version 1.8 support Android 12 and above, also the develop mainline. Version 1.7 support Android 11 and below, drop down some spicetify functions for Android 12 to make app useable on lower Android System
+There are two development branches: 1.8.x.x and 1.7.x.x . Version 1.8 only support platform api 31 (aka Android S) and above, also the develop mainline. Version 1.7 should only be used on Android 11 and below, since these platforms lack native api of image decoding.
