We are pleased to announce the release of GNUnet 0.16.0.
This is a new major release. It breaks protocol compatibility with the 0.15.x versions. Please be aware that Git master is thus henceforth (and has been for a while) INCOMPATIBLE with the 0.15.x GNUnet network, and interactions between old and new peers will result in issues. 0.15.x peers will be able to communicate with Git master or 0.16.x peers, but some services - in particular GNS - 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 0.16.0 release is still only suitable for early adopters with some reasonable pain tolerance.

Noteworthy changes in 0.16.0 (since 0.15.3):
GNS:
- New record flag: CRITICAL. For records that must be processed otherwise resolution must fail. #7169
- Deletion of records and reduction of expiration times is now properly handled with respect to monotonically increasing expiratin times. #7170
- VPN tunnel establishment is moved out of the GNS resolver to be handled by applications (such as the DNS2GNS service). #7171
- Introduces new record type REDIRECT which replaces the previous (ab)use of CNAME records. #7172
- The specification has been updated to reflect the changes. https://lsd.gnunet.org/lsd0001
DHT:
- Routes can now be signed. #4164
- Changed distance metric to a more traditional XOR. #7136
- The specification has been updated to reflect the changes. https://lsd.gnunet.org/lsd0004
RECLAIM: Added some preliminary support for Decentralized Identifier (DID) and Verifiable Credentials (VCs).
UTIL: Add Clause-Schnorr blind signatures. For use in Taler (https://taler.net/en/news/2022-02.html).
BUILD: Building from git now requires recutils. The bootstrap will generate up-to-date header files from https://gana.gnunet.org/.
