I agree, discord.py has been pleasant to use. However up until this gist, discord.py was lacking newer API features, most notably slash commands, and was otherwise abandoned.

I'm not clear on the details but if you aren't currently using slash commands you may be forced to in the near future so if you have any operating bots responding to custom prompts you should look into whether you need to do some work or not.

Now on what library to use... there have been various discord.py derivative projects to provide slash commands and now discord.py apparently supports them too. Personally I'm avoiding discord.py, I can't trust they'll continue development and I'm not trying to track community drama via discord. I also really dislike node. My solution for now is discord.js as a thin layer between discord and python.
