I think the copy and paste approach needs to flesh out the exact 
procedure that needs to happen at the start of development on 
that release. For instance, should the std folder be copy/pasted 
with the result re-named `std_v_x_xx`. This would break code if 
people stay on std. So maybe the new `std` should be `std2` with 
folders saved as `std2_v_x_xx`?

What about creating aliases for each year's release? So for 
instance, `alias std_yyyy = std_v_x_xx;`? And then increment it 
as new releases come out each year, until the final one. It would 
be nice to alias an entire module or package, but otherwise would 
need to have some automated approach to add in the aliases.
