I want to know what makes a patch level in Ruby. What is a patch level? Is it just a different version of Ruby that has been released? I understand that https://www.ruby-lang.org gives good notes on the differences between the patches themselves, but I'm still unsure of what a patch level is, and if it's different from a patch.
What is a patch level, compared to a version? Is there a difference between a patch, a patch level and a version? Is there anywhere where these kinds of definitions can easily be looked up? (I have tried googling.)
Thank you.
