GNUnet 0.13.0 released

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 tolerance.

Noteworthy changes in 0.13.0 (since 0.12.2)

• GNS:
  • 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
• 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.
• UTIL:
  • 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.
• Packaging: ?
• GANA Registry: GANA
• LSD subdomain and LSD0001 website:: LSD0001
• Continuous integration: Buildbot set up.
• Buildsystem: A significant number of build system changes:
  • libmicrohttpd and libjansson are now required dependencies.
  • New dependencies: argon2 and libsodium.

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 bugs.gnunet.org which lists about 190 more specific issues.
