Stan and Math v2.12 have been released

[Daniel Lee]

We actually have a lot of fixes in the Stan library this time around. A few fixes for Stan programs that would parse, but the generated C++ wouldn't compile. And we fixed some, but not all, of the truncation issues.

I'm attached the release notes below. They're also available on the GitHub releases:

https://github.com/stan-dev/stan/releases/tag/v2.12.0

P.S. I've intentionally not put this on stan-users or stan-announce yet. Once at least one of the interfaces is released, we'll announce it there and on Andrew's blog.
