In this post: [What is the difference between CB3.1 and CB3.0](https://forum.universal-robots.com/t/what-is-the-difference-between-cb3-1-and-cb3-0/129)  
I readed that:

**1. Debian version**  
a. CB3.0: Debian GNU/Linux 5.0  
b. CB3.1: Debian GNU/Linux 7.8  
**2. Java version**  
a. CB3.0: 1.6  
b. CB3.1: 1.6  
**3. Python version**  
**a. CB3.0: 2.5**  
**b. CB3.1: 2.7**

But what about E series? what version does it runs?
