## 6. Configuration

### 6.1 Configuration Properties
```java
// In PropertyConfiguration.java

 *  Fix: When parsing HTTP authentication headers permit challenge parameters in any order.


## Version 3.4.2

_2016-11-03_

 *  Fix: Recover gracefully when an HTTP/2 connection is shutdown. We had a
    bug where shutdown HTTP/2 connections were considered usable. This caused
    infinite loops when calls attempted to recover.
