Hi! Thanks for the PR, did you check for the imports in the codebase about these methods that should be fixed?

[matteocacciola]

I guess this should be self.history[-latest_n:], isn't it?

[matteocacciola]

As above

[giovannimarra]

Yes, I missed it. I'm going to fix it now.

For the imports in codebase @zAlweNy26, I checked in which files the methods were called but I didn't see a direct import to the old file stray_cat where they were, so I didn't edit it. Maybe I didn't read it correctly ?

I updated the code on my branch because i read it on contributing.md, is it wrong ?

[giovannimarra]

I'm getting confused, I commited and pushed on my branch but if i search for the methods it's like nothing changed, what i'm doing wrong
