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.
