Out of curiosity, why are you still using v2?

Thank you for the merge!

Out of curiosity, why are you still using v2?

Mainly because I still need to support old compilers like GCC 4.9 or MSVC 2015 in some of the projects where I use Catch2.
In one of these projects, I actually upgraded to v3 at some point, but then had to go back to v2 for this reason.
I'll definitely upgrade to v3 as soon as I can raise the minimum requirements for them.
