  o Minor features (authorities):
    - Authorities now list a different set of protocols as required and
      recommended.  These lists are chosen so that only truly recommended
      and/or required protocols are included, and so that clients using 0.2.9
      or later will continue to work (even though they are not supported),
      whereas only relays running 0.3.5 or later will meet the requirements.
      Closes ticket 40162.
Update required/recommended protocol versions. Cons=1 is the old format of consensuses, without ed25519 keys. It is no longer required or recommended. Cons=2 is the new format of consensuses, with ed25519 keys. It is now required. (Similarly for Desc=1,2 and Microdesc=1,2) No supported client or relay versions should be affected by this change, since these versions are supported by clients and relays running 0.2.9 and later. It will only take effect once enough authorities vote for it. Closes ticket 40162. 2020-10-18 22:09:25 +02:00			`o Minor features (authorities):`
Update required/recommended protocol lists more systematically First I began with a set of candidates: The client's _required_ list starts with all the protocols supported by every release in 0.2.9-stable through current master. The client's _required_ list starts with all the protocols supported by every release in 0.3.5-stable through current master. Everybody's _recommended_ list starts with all the protocols supported by every release in 0.3.5-stable through current master. Then I removed the protocol versions that we do not actually want to require or recommend: DirCache=1 (deprecated) HSDir=1, HSIntro=1-3, HSRend=1 (deprecated) (All HS* protocol requirements for clients) Link=1-3 (deprecated) LinkAuth=1 (obsolete) Relay=1 (obsolete) 2020-10-23 17:23:08 +02:00			`- Authorities now list a different set of protocols as required and`
