Note: 1.6.1 is the current release. 1.6.0 was tagged but not released.

This release completes the rollout of two major protocol updates developed in 2021. The transition to X25519 encryption for routers is accelerated, and we expect almost all routers to be rekeyed by the end of the year. Short tunnel build messages are enabled for a significant bandwidth reduction.

We added a theme selection panel to the new install wizard. We've improved SSU performance and fixed an issue with SSU peer test messages. The tunnel build Bloom filter was adjusted to reduce memory usage. We have enhanced support for non-Java plugins.

In other news, we are making excellent progress on the design of our new UDP transport SSU2 and expect to start implementation early next year.

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.
