title: Kotlin 1.3.72 Using andriod extention or should I change. Is it safe?
body: <p>Good day.</p>
  <p>I am somewhat new to kotlin and android development. I found a helpful guide from a few years ago it uses kotlin extensions which I have come to release is a bit outdated and no longer used. I built my app with this &quot;old&quot; code. Not upgrading my kotlin. The app works fine. It will be used as an inhouse app to manage some stuff. Is there a good reason for me to change to the new version of the code?</p>
  <p>Thank you for all inputs and opinions.</p>
