The big change in Enarx 0.2.0 is the addition of support for networking. Until now, there wasn’t much you could really do in an Enarx Keep, honestly: you could run an application, but all it could to for input and output was read from stdin and write to stdout or stderr. While this was enough to prove that you could write and compile applications to WebAssembly and run them, any more complex interaction with the world outside the Keep was impossible. So, why is this big news? Well, now it’s possible to write applications that you can talk to over the network.
