GNUnet 0.22.0 released

We are pleased to announce the release of GNUnet 0.22.0.

GNUnet is an alternative network stack for building secure, decentralized and
privacy-preserving distributed applications.
Our goal is to replace the old insecure Internet protocol stack.
Starting from an application for secure publication of files, it has grown to
include all kinds of basic protocol components and applications towards the
creation of a GNU internet.

This is a new major release.
It breaks protocol compatibility with the 0.21.x versions.
Please be aware that Git master is thus henceforth (and has been for a
while)

INCOMPATIBLE

with
the 0.21.x GNUnet network, and interactions between old and new peers
will result in issues.
In terms of usability, users should be aware that there are still

a number of known open issues

in particular with respect to ease
of use, but also some critical privacy issues especially for mobile users.
Also, the nascent network is tiny and thus unlikely to
provide good anonymity or extensive amounts of interesting information.
As a result, the 0.22.0 release is still

only suitable for early adopters
with some reasonable pain tolerance
