The new version of WildFly brought many changes, all for the better, of course, and it has many updated features, many libraries, several bugs, and problems that existed earlier and no longer exist in the WildFly final version. A big change for applications that use old libraries is that we will have to change the version of the module. A great example of this is Hibernate; many applications use Version 3 and are incompatible with the native WildFly version. Similarly, the following components have been modified in WildFly 8:
