After almost half a year of inactivity, we release updates for both Android and iOS.
FBReader Premium 3.0.25 and 3.1 beta 21 for Android, and 1.0.19 for iOS fix Yandex.Translate issue. Recently in this August, Yandex changed their translation API, as well as requirements for partners. We try to manage this problem, and as a temporary solution, FBReader will use Google.Translate interface instead. Hopefully, Yandex.Translate integration will be back soon.
