@wds15, thanks for tagging me. I think this means we bump the major version. I think @seantalts is supposed to make the call, but after we make a suggestion.
What do you think? This seems like it changes what we used to be as the Math library. We’re no longer a header-only with optional link library for certain things. And… we have a new library dependency. If you’re using Math and are GPLv2 and distribute the code, then you will be in violation after this new release.
