PettingZoo 1.23.0

PettingZoo 1.23.0 Release Notes:

This release finishes the process of standardizing the PettingZoo API to fully match Gymnasium. The deprecated env.seed() method has been removed in favor of env.reset(seed=seed), and the return_info argument from reset() has been removed—info is now always returned on reset.

New features include full support for serialization using Pickle, and updated testing: pickle tests, improved API test, and re-written seed test (matching Gymnasium). The library has also been updated to use pyproject.toml, to make installation more consistent and reliable, and to comply with PEP 621 standards.

This release includes significant documentation updates: full installation and usage examples for each environment type (Atari, Butterfly, Classic, MPE, SISL), 9+ new third-party-environments, new action masking documentation, new LangChain tutorial, updated CleanRL, Tianshou, and RLlib) tutorials, and more.

Breaking Changes:

To ensure full consistency between the PettingZoo and Gymnasium API’s, the following changes have been made:

The deprecated environment seed() method has been fully removed.

• To seed an environment, call env.reset(seed=0)

The return_info argument has been removed from the reset() function.

• Calls toreset() will now always return observation and info.
