3.0.0

• Full refactor of ordinary wrappers
  • Most supersuit wrappers now have a single, generic implementation that works for gym and pettingzoo envs. This makes adding new wrappers much easier.
  • File structure is reorganized.
• Added scale_actions_v0 wrapper
• Added nan_noop, nan_zeros, and nan_random wrappers to handle nan actions in a reasonable way. Important to deal with RL frameworks that occasionally give out nan values.
• cv2 package is only imported when needed

2.6.6

• Patch release to remove dependency on functionality removed in pettingzoo 1.9.0

2.6.5

2.6.4

• various minor fixes for vector environments and stable baselines

2.6.3
