How do I find out which version of GMod I have?

I know I bought GMod 10. But how do i know if it’s updated to gmod 11?

Have you connected to the internet since early 2008?
If so, you’ve got GMod 11.

He obviously has since he’s posting here

Just to be clear, there are no longer version numbers.

If you bought Gmod off Steam, you have the newest version.

And due to Steam’s automatic updates, you will always have the newest version.

Yup

Version #075 according to build version.

It auto updates. You have 11 if you opened steam up this year.

There is no version 11. I cant understand why people keep confusing new people with it

Really it’s Gmod 10.2
