New Features

Java 8 supported

Java 8 is now supported and required to use PureLoad.

Added possibility to reference/use other sequences within PLC file

Now common sequences can be referenced from multiple scenarios to provide a way to structure scenarios with common sequences.

Linux Any-IP support and creating massive amount of connections

Using Any-IP is a new (preferred) alternative to using the PureSNAT kernel module to simulate many IP addresses. The advantage being that Any-IP support is included with modern Linux distributions and also allows creating more connections on a host. See the documentation for more details.

To support Any-IP a new task is introduced: IpSocketInitTask to set socket options. The option IP_TRANSPARENT is required to support_Any-IP, but SO_REUSEADDR can also be used to reuse connections and to be able to create massive amount of connections.
