    July 05, 2016
    • 0️⃣ [BREAKING] Generics handling is more robust now, the former optimization for smaller size (but increased serialization time) is now optional and disabled by default.

    Important: This change breaks the serialization format of the FieldSerializer for generic fields, therefore generic classes serialized with Kryo 3 and FieldSerializer cannot be deserialized with Kryo 4 by default. To deserialize such Kryo 3 serialized generic classes you have to set kryo.getFieldSerializerConfig().setOptimizedGenerics(true);!

    👀 For details see #433: Disable the optimization of generics serialization and provide an API for enabling/disabling it (9923d05).
