v0.4.0

Summary

This release brings new features and improvements, following our roadmap to the v0.2 Logos Testnet. Among the most important improvements:

1. new block protocol - much more memory efficient, capable of fully utilizing libp2p throughput. It's already faster than what we had before, but should reach bittorent-level speeds once we move to QUIC;
2. private DHT queries - as part of our effort towards anonymous filesharing, we are rolling out support for DHT queries over the new Logos mix network.

We will also roll out much more advanced support for NATs in a follow up release, so stay tuned.
