commit b67f7d722d4cb94d1e77ff9b300c82d8c72b14c3 Author: Nick Mathewson <nickm(a)torproject.org> Date: Wed Jun 17 11:00:58 2020 -0400 Update the list of recommended protocol versions to match >=0.3.5. Since Tor 0.2.9 has been unsupported since January, 0.3.5 is the oldest supported version, and its features constitute the oldest recommended feature-set. This patch updates these recommendations: DirCache=2 Support for consensus diffs. New in 0.3.1.1-alpha. HSDir=2 Support for v3 onion service descriptors. New in 0.3.0.4-alpha. HSIntro=4 Support for Ed25519 intropoint authentication keys. New in 0.3.0-4-alpha. HSRend=2 Support for rendezvous cells longer than 20 bytes. New in 0.2.9.4-alpha. Link=5 Link padding and link padding negotiation. New in 0.3.3.2-alpha. LinkAuth=3 Ed25519 link authentication. New in 0.3.0.1-alpha. --- changes/ticket32696 | 7 +++++++ src/feature/dirauth/dirvote.h | 8 ++++---- 2 files changed, 11 insertions(+), 4 deletions(-) diff --git a/changes/ticket32696 b/changes/ticket32696 new file mode 100644 index 000000000..8f56fc394 --- /dev/null +++ b/changes/ticket32696 @@ -0,0 +1,7 @@ + o Minor features (directory authority): + - Authorities now recommend protocol versions that are supported + by Tor 0.3.5 and later.
