GNUnet 0.12.0 released

From: Schanzenbach, Martin
Subject: GNUnet 0.12.0 released
Date: Fri, 20 Dec 2019 10:28:59 +0900

We are pleased to announce the release of GNUnet 0.12.0.

This is a new major release. It breaks protocol compatibility with
the 0.11.x versions. Please be aware that Git master is thus henceforth
INCOMPATIBLE with the 0.11.x GNUnet network, and interactions between
old and new peers will result in signature verification failures.
0.11.x peers will NOT be able to communicate with Git master or 0.12.x
peers. 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 and thus unlikely to provide good
anonymity or extensive amounts of interesting information. As a result,
the 0.12.0 release is still only suitable for early adopters with some
reasonable pain tolerance.

Noteworthy changes in 0.12.0 (since 0.11.8):

- GNS:
  - Changed key derivation protocols to adhere with LSD001. #5921
  - Names are not expected to be UTF-8 (as opposed to IDNA). #5922
  - NSS plugin now properly handles non-standard IDNA names. #5927
  - NSS plugin will refuse to process requests from root (as GNUnet code
    should never run as root). #5907
  - Fixed BOX service/protocol label parsing (for TLSA et al)
- GNS/NSE: Zone revocation proof of work algorithm changed to be less
           susceptible to specialized ASIC hardware. #3795
- TRANSPORT: UDP plugin moved to experimental as it is known to be unstable.
  - Improved and documented RSA binary format. #5968
  - Removed redundant hashing in EdDSA signatures. #5398
  - New gnunet-logread binary for log auditing (requires perl) can now be 
  - Now using TweetNaCl for ECDH implementation.
- Buildsystem: A significant number of build system issued have been fixed and
  improvements implemented, including:
  - GLPK dependency dropped.
  - Fixed guix package definition.
- Documentation: Improvements to the handbook and documentation.

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 which lists about 190 more specific issues.

This release was the work of many people. The following people contributed code 
were thus easily identified: ng0, Christian Grothoff, Florian Dold, xrs, Naomi 
and Martin Schanzenbach.
