0.9.50 continues the transition to ECIES-X25519 for router encryption keys. We have enabled DNS over HTTPS for reseeding to protect users from passive DNS snooping. There are numerous fixes and improvements for IPv6 addresses, including new UPnP support.

We have finally fixed some longstanding SusiMail corruption bugs. Changes to the bandwidth limiter should improve network tunnel performance. There are several improvements in our Docker containers. We have improved our defenses for possible malicious and buggy routers in the network.

As usual, we recommend that you update to this release. The best way to maintain security and help the network is to run the latest release.
