I very much like the library maintainers (meaning me!) adding a new 
version to an interface whenever it has to change.  Then the caller by 
default gets the current one, with the security bugs fixed, but can 
specify an old one of they need a different semantics. (Or, horror of 
horrors, if they currently depend on the bug)

We did that a lot inside Sun, and the Linux glibc maintainers do too: it 
made my work a _lot_ easier when stuff was changing quickly.
