[pseudo-rnd-thoughts]

Bug 1.
Gym version number is 0.21.0 while the most recent release is 0.22.0
https://github.com/openai/gym/blob/master/gym/version.py
https://github.com/openai/gym/releases/tag/0.22.0

Bug 2.
I have cloned the repository and tried to create an atari environment however it throws an error about the seed

This git commit appears to be the cause of the problem - 2be9e60
The problem doesn't occur with the previous commit - 8819d56

But I can't work out what the issue is as the commit doesn't change any of the code in envs/atari/environment.py

Hey, thanks a ton, I'm really glad you caught these before we pushed to PyPI. I just fixed the version on master, #2625 will fix the bigger issue.

Additionally- would be be interested in working on contributions to Gym going forward?

@jkterry1 Thanks, it was mostly luck that I found the issues

For contributing towards Gym in the future, I would be happy to help.
I noticed the roadmap for 1.0 (#2524)
Is there anything else to work on? And to discuss what different people are working on?
