I had a random thought recently about the possibility of storing single 
character strings entirely in a TValue. Or up to 3/7 characters depending on 
word size. On the other hand, you've got yet another value type. And what 
happens to the C pointer to the string when the value is moved around the 
stack?

As to the version string, I for one do not worship at the altar of Semantic 
Versioning which I believe makes the false assumption that a "mere" bug fix is 
a non-breaking change. Any change, no matter how small, has the potential to 
break something and assuming your code will act the same when the minor number 
changes is no excuse for complacency.
