Note the remark: "Prior to 1.0, minor releases follow the rules for 
major releases, except they are still made every few months."

So, since we're still pre-1.0, we try to remove deprecated features in 
the next minor release after they're deprecated.  We don't always manage 
to do this.  Some deprecated features have survived a long time, 
especially when they're widely used internally.

When deprecated code is removed the change is described in the 
"incompatible" section of the release notes.
