What does the term Clang TOT refer to?

Question

I wanted to try out some new features in Clang, and I was referred to Clang TOT.

Now this might be an obvious question by what the heck is Clang TOT.

TOT must be some acronym that I am not familiar with.

Can anyone enlighten me?

Answer 1

Maybe means "top of (the) tree", as in the latest code in a source code repository.
