GNUnet 0.19.0 released

We are pleased to announce the release of GNUnet 0.19.0.

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 0.18.x versions.
Please be aware that Git master is thus henceforth (and has been for a
while)

INCOMPATIBLE

with
the 0.18.x GNUnet network, and interactions between old and new peers
will result in issues. 0.18.x peers will be able to communicate with Git
master or 0.19.x peers, but some services 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 0.19.0 release is still

only suitable for early adopters
with some reasonable pain tolerance

.

Noteworthy changes in 0.19.0 (since 0.18.2)

• 
  UTIL
  
  : Moved
  
  GNUNET_BIO_MetaData
  
  handling into
  
  FS
  
  .
• 
  BUILD
  
  :
  
  platform.h
  
  removed as it should not be used by
  third parties anyway.
  
  gnunet_config.h
  
  is renamed to
  
  gnunet_private_config.h
  
  and the new replacement
  
  gnunet_config.h
  
  is added to provide
  build information for components linking against/using GNUnet.
• 
  UTIL
  
  : Components part of
  
  gnunet_util_lib.h
  
  must now
  be included through
  
  gnunet_util_lib.h
  
  and through that header
  
  only
  
  .
• 
  NAMESTORE
  
  :
  
  gnunet-namestore
  
  can now parse a list of records into zones
  from
  
  stdin
  
  in new
  
  recordline
  
  format.
• 
  GTK
  
  : Added an identity selector to the search to accomodate for
  previously deprecated "default" identities for subsystems.
• Other: Postgres plugins implementations modernized and previous regressions
  fixed.

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.
