This is an UNSTABLE release of Mongoose

Just trying to get the lowdown on "This is an UNSTABLE release of Mongoose"

I have version 3.8.16:

 $ npm list mongoose
 myapp@0.0.1 /Users/me/dev/myapp/src
 └── mongoose@3.8.16 

This page says that odd versions are unstable and even versions are stable:

http://blog.mongodb.org/post/58318358173/mongoose-3-7-0-unstable-released

So is it a mistake that version 3.8.16 has "This is an UNSTABLE release of Mongoose" in

 myapp/src/node_modules/mongoose/lib/index.js?
