Hello Guys, 
 
At our company we had to downgrade the EDC from 0.9.0 to 0.5.4 our apps throws this exception below 
(where mainly caused by empty config properties) 
 
Caused by: java.lang.reflect.InvocationTargetExceptionat java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

So, my question is : 
Is there any source where I can check what properties needed to 0.5.4 ?  
Is there any documentation for specific releases or we only have changelog ?  
What is the best way to putting together a small dataexchange with version 0.5.4 ? 
 
Thanks in advance,
