 To use gem in a Rails app, add the following to your `Gemfile`:
 
-    gem "russianpost", "~> 0.5.0"
+    gem "russianpost", "~> 0.5.1"
 
 This gem uses [Savon](http://savonrb.com/), which in turn uses [HTTPI](https://github.com/savonrb/httpi) internally. HTTPI chooses the best HTTP library of those you have installed. For the fastest results, make sure you add [Curb](https://github.com/taf2/curb) to your `Gemfile`:
 
     gem "curb"
     gem "russianpost"
