 If you don't use Maven (or something else that understands Maven dependencies, like Gradle), you can [download Pushy as a `.jar` file](https://github.com/jchambers/pushy/releases/download/pushy-0.15.4/pushy-0.15.4.jar) and add it to your project directly. You'll also need to make sure you have Pushy's runtime dependencies on your classpath. They are:
 
-- [netty 4.1.104](http://netty.io/)
+- [netty 4.1.111](http://netty.io/)
 - [slf4j 1.7](http://www.slf4j.org/) (and possibly an SLF4J binding, as described in the [logging](#logging) section below)
 - [fast-uuid 0.1](https://github.com/jchambers/fast-uuid)
