body: I'm developing a mobile app and I'm using GitHub for source code which is set to public, so I can show my friends.
  
  
  I was using some free icons from www.flaticon.com/home , which required the developer to attribute the authors to the icons. 
  
  
  But I decided to go ahead and just create my own icons and delete all the icons I was using the flaticon, but the problem is in the previous commits on GitHub, the old images of the icons are still visible in my resource folders. 
  
  
  Is this a problem I need to address at all? Do I need to mention anywhere that I WAS using icons from FlatIcon or am I good to just act like it never happened? 
  
  
  Thanks!
