GNUnet 0.22.0 released

[Martin Schanzenbach]

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 the0.21.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.

Changes:

A detailed list of changes can be found in the git log, the NEWS and
the 
bug tracker.
Noteworthy highlights are

    transport:
        A new experimental HTTP/3 communicator for peer-to-peer
transport communicator.
        New experimental NAT traversal functionality.

    util:
        An implementation of Hybrid Public Key Encryption (HPKE) and
related KEMs which are now used across the stack.
        An implementation of Elligator used as part of our Diffie-
Hellman exchanges and KEMs

    hostlist: The bootstrap URL is changed to
https://bootstrap.gnunet.org/v22 and
https://bootstrap.gnunet.org/latest for the release and development
version (git head), respectively.

    gnunet-hello: A new CLI to import/export connectivity information
(HELLOs) of peers manually.
    namestore: Significant zone import performance improvements in
preparation for DNS TLD mirror deployments (.se, .nu, etc).

    messenger:

streaming in chat rooms.
        New functionality in CLI for the Messenger service to stream
data via standard input and output.

    Build System:
        Build variant to build a monolithic GNUnet library.
        Cross compile the monolithic library for use on Android
devices. An Android prototype can be found in this repository:
https://git.gnunet.org/gnunet-android.git

Known Issues:

     - There are known major design issues in the CORE subsystems which
will need to be addressed in the future to achieve acceptable
usability, 
performance and security.
     - There are known moderate implementation limitations in CADET
that 
negatively impact performance.
     - There are known moderate design issues in FS that also impact 
usability and performance.
     - There are minor implementation limitations in SET that create 
unnecessary attack surface for availability.
     - The RPS subsystem remains experimental.

In addition to this list, you may also want to consult our bug tracker 
at https://bugs.gnunet.org/ which lists about 190 more specific issues.
