Changelog#

2.20.0 (2026-10-07)#

Fix#

  • Document the security implications of pygmo’s use of pickle/cloudpickle for the (de)serialization of user-defined problems, algorithms, islands, etc.: deserialising pygmo objects from an untrusted source is equivalent to arbitrary code execution, exactly as with the standard pickle module. No sandboxing or validation is (or can be) performed on unpickled data.
