Today Sony mobile has released an update for the Small App framework to version 1.0.A.0.1. There are no much changes. But Sony says that the update improves
Small App search results on the Google Play Store, although Xperia Blog says they didnt notice any difference pre and post update. We can expect that this update may make the required environment for the new material design Small Apps as seen in
the new Xperia Z5 series to work on older devices. The Update is rolling out via the Whats New App on Android Lollipop and Update Center on Kitkat and lower.
