 ## Auto3DSeg: JSON-Based Algo Serialization
 
-Auto3DSeg algorithm objects are now serialized using JSON instead of pickle. This removes a class of security risks associated with pickle deserialization and improves cross-environment portability of saved algorithm states. Using pickle for serialization can be re-enabled by setting the environment variable `MONAI_ALLOW_PICKLE` to `1` or the equivaent true value.
