I'd probably rewrite this as:

`Prior to version 0.1.9, these methods were known by the names shown below. In 0.1.9, these methods are marked as deprecated. They will still work, but will log a warning about their pending removal. From 0.2.0 onwards, these aliases will be removed.`

I would then remove the `Caveat` line, and probably drop the method signatures in the list, since they're the same as the new function name.
