The new Chiron 4 is about 70 points stronger than Chiron 3, according to the author Ubaldo Andrea Farina. Although it's an update to the engine, the Android app is a different one and will keep Chiron 3 alive on the same device. Interested users can even make two versions play each other the same way as it's possible between Komodo versions.
Chiron 4 costs 2.5 EUR only and the licence checking works exactly like Komodo via Google Play.
