That certainly seems to be the case. I'm happy with 3.4.x.

Is CMake like Linux that the even releases are stable and odd are
experimental (or vice versa)?
If not, I think we can safely update to CMake M.N as soon as M.N+1 is
declared "stable". This worked before with 2.8, and should work with

This is a big issue now because we're still relying on what's on the distros.
As soon as we officially move to built-in, and as long as we keep our
documentation in order, and make sure to mention strict versions and
build methods (no git, only tarballs), then moving CMake versions
won't be a big issue.
