We are pleased to announce the release of GNUnet 0.15.0.
This is a new major release. It breaks protocol compatibility with the 0.14.x 
versions. Please be aware that Git master is thus henceforth INCOMPATIBLE with 
the 0.14.x GNUnet network, and interactions between old and new peers will 
result in issues. 0.14.x peers will be able to communicate with Git master or 
0.14.x peers, but some services - in particular GNS - will not be compatible.
The MESSENGER service goes out of experimental to be used by libraries and 
applications as dependency. It handles decentralized messaging in flexible 
groups by using the CADET service and messages can be signed with your ego from 
the IDENTITY service. The service is still in an early stage, so its protocol 
(currently version 0.1) will likely adapt or change in future releases to some 
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 0.15.0 release is still only suitable 
for early adopters with some reasonable pain tolerance.
