GNUnet 0.23.0 released

We are pleased to announce the release of GNUnet 0.23.0.
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 0.22.0X versions. Please be aware that Git master is thus henceforth (and has been for a while) INCOMPATIBLE with the 0.22.0X 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 0.23.0 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

  • Code review: A number of issues found during a code review have been addressed.
  • util: A GNUNET_OS_ProjectData must now be passed to some APIs that are commonly used by third parties using libgnunetutil (e.g. Taler, GNUnet-Gtk) as to properly handle cases where the GNUnet installation directory is different from the third-party directory.
  • Build System: Improved build times by outsourcing handbook to prebuilt files and only generating GANA source files manually.

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