Well, Rails. And many SWIG-based C-extensions - eg wxRuby.

But this misses the main point - that there is no assurance that code 
developed using 1.8.7 (or 1.8.8) will run on 1.8.6. And no way of 
checking, other than scrutinising the ChangeLog. This is a huge 
disservice to library authors and users.
