Questiona about verl version and difference

Hi thank you for publishing your work.
they are very helpful!

i just wanted to ask which verl version you have used and what you have modified in its source code. 
I saw that you've made some notes with the comment "NOTE from meow-tea" 

is it safe to assume that those are all changes you have made to the source code?
Thank you and have a nice day!

Kind regards,
Yumi
