 # GO JWT Middleware
 
+**NOTE:** We released this version using a fork of jwt-go in order to address a security vulnerability. Due to jwt-go not being actively maintained we will be looking to switch to a more actively maintained package in the near future.
+
 A middleware that will check that a [JWT](http://jwt.io/) is sent on the `Authorization` header and will then set the content of the JWT into the `user` variable of the request.
 
 This module lets you authenticate HTTP requests using JWT tokens in your Go Programming Language applications. JWTs are typically used to protect API endpoints, and are often issued using OpenID Connect.
