I forgot to mention (and was kindly reminded by Jon Degenhardt), this is 
the first release where Martin's std.io library 
(https://github.com/MartinNowak/io) is optional. In the future, iopipe 
will remove this dependency. The only thing that depends on std.io is 
the deprecated `openDev` function.

So if you were expecting iopipe to bring in that dependency, you will 
have to add it to your dub.json/dub.sdl file.
