GNUnet 0.11.6 released

We are pleased to announce the release of GNUnet 0.11.6.
This is a bugfix release for 0.11.5, fixing a lot of minor bugs, improving stability and code quality. Further, our videos are back on the homepage. In this release, we again improved the webpage in general and updated our documentation. As always: 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 (about 200 peers) and thus unlikely to provide good anonymity or extensive amounts of interesting information. As a result, the 0.11.6 release is still only suitable for early adopters with some reasonable pain tolerance.

Download links

gnunet-fuse was not released again, as there were no changes and the 0.11.0 versions are expected to continue to work fine with gnunet-0.11.6.

Note that due to mirror synchronization, not all links might be functional early after the release. For direct access try

Noteworthy changes in 0.11.6 (since 0.11.5)

  • gnunet-identity can now print private keys.
  • The REST service can be configured to echo the HTTP Origin header value for Cross-Origin-Resource-Sharing (CORS) when it is called by a browser plugin. Optionally, a CORS Origin to echo can be also be directly configured.
  • re:claimID tickets are now re-used whenever possible.
  • SUID binary detection mechanisms implemented to improve compatiblity with some distributions.
  • TRANSPORT, TESTBED and CADET tests now pass again on macOS.
  • CADET: Replaced enum GNUNET_CADET_ChannelOption with GNUNET_MQ_PriorityPreferences in preparation of API changed in the future.
  • The GNS proxy Certification Authority is now generated using gnutls-certtool, if available, with opennssl/certtool as fallback.
  • Documentation, comments and code quality was improved.

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.
