GNUnet 0.17.0 released
We are pleased to announce the release of GNUnet 0.17.0.
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 0.16.x versions.
Please be aware that Git master is thus henceforth (and has been for a
the 0.16.x GNUnet network, and interactions between old and new peers
will result in issues. 0.16.x peers will be able to communicate with Git
master or 0.17.x peers, but some services - in particular the DHT - will not be compatible.
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 0.17.0 release is still
only suitable for early adopters
with some reasonable pain tolerance

Noteworthy changes in 0.17.0 (since 0.16.3)
- FCFSD: Allow configuration of relative expiration time of added records.
Aligned with breaking changes in specification.
- Fix scheduler bug with same-priority immediately-ready tasks possibly hogging the scheduler.
- Fix mysql/mariadb detection.
- 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.
