GNUnet 0.13.0 released

From: Schanzenbach, Martin
Subject: GNUnet 0.13.0 released
Date: Tue, 7 Jul 2020 19:49:12 +0200

We are pleased to announce the release of GNUnet 0.13.0.

We are pleased to announce the release of GNUnet 0.13.0.
This is a new major release. It breaks protocol compatibility with
the 0.12.x versions. Please be aware that Git master is thus
henceforth INCOMPATIBLE with the 0.12.x GNUnet network, and interactions
between old and new peers will result in signature verification failures.
0.12.x peers will NOT be able to communicate with Git master or 0.13.x peers.
In terms of usability, users should be aware that there are still a large
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 0.13.0
release is still only suitable for early adopters with some reasonable pain

Noteworthy changes in 0.13.2 (since 0.12.2):

 - Aligned with specification LSD001.
 - NSS plugin "block" fixed. #5782
 - Broken set NICK API removed.#6092
 - New record flags: SUPPLEMENTAL. Records which are not explicitly
   configured/published under a specific label but which are still
   informational are returned by the resolver and flagged accordingly. #6103
 - gnunet-namestore now complains when adding TLSA or SRV records
   outside of a BOX

CADET: Fixed tunnel establishment as well as an outstanding bug regarding
       tunnel destruction. #5822

GNS/REVOCATION: Revocation proof of work has function changed to argon2
                and modified to reduce variance.
RECLAIM: Increased ticket length to 256 bit. #6047

TRANSPORT: UDP plugin moved to experimental as it is known to be unstable.

 - Serialization / file format of ECDSA private keys harmonized with other
   libraries. Old private keys will no longer work! #6070
 - Now using libsodium for EC cryptography.
 - Builds against cURL which is not linked against gnutls are now possible
   but still not recommended. Configure will warn that this will impede the
   GNS functionality. This change will make hostlist discovery work more
   reliable for some distributions.
 - GNUNET_free_non_null removed. GNUNET_free changed to not assert that the
   pointer is not NULL. For reference see the Taler security audit.
 - AGPL request handlers added GNUnet and extension templates.

(NEW) GANA Registry: We have established a registry to be used for names and
                     numbers in GNUnet. This includes constants for protocols
                     including GNS record types and GNUnet peer-to-peer 
(NEW) Living Standards: LSD subdomain and LSD0001 website: LSD0001

(NEW) Continuous integration: is back.

Buildsystem: A significant number of build system changes:
 - libmicrohttpd and libjansson are now required dependencies.
 - New dependency: libsodium.
 - Fixed an issue with libidn(2) detection.

A detailed list of changes can be found in the ChangeLog and the 0.13.0
bugtracker at

Known Issues

- There are known major design issues in the TRANSPORT, ATS and 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.
- Some high-level tests in the test-suite fail non-deterministically due
to the low-level TRANSPORT issues.

In addition to this list, you may also want to consult our bug tracker
at which lists about 190 more specific issues.

This release was the work of many people. The following people contributed code
and were thus easily identified: Christian Grothoff, Florian Dold, Jonathan 
t3sserakt, nikita and Martin Schanzenbach.
