According to proposal 303, we recommend some protocol versions every time
an LTS release is no longer supported:
https://gitweb.torproject.org/torspec.git/tree/proposals/303-protover-
removal-policy.txt#n18
0.2.9.8 supported these protocol versions:
https://gitweb.torproject.org/tor.git/tree/src/or/protover.c?h=tor-0.2.9.8#n283
When 0.2.9 is no longer supported, the earliest stable LTS will be
0.3.5.7, which supports these protocol versions:
https://gitweb.torproject.org/tor.git/tree/src/core/or/protover.c?h=tor-0.3.5.7#n379
Therefore, we should recommend these protocol versions for clients and
relays:
Cons=2
Desc=2
DirCache=2 *
HSDir=2 *
HSIntro=4 *
HSRend=2
Link=5 *
LinkAuth=3 *
Microdesc=2
Relay=2
The starred protovers are not supported by 0.2.9, so it will warn on
bootstrap / consensus download.
We can make that change in master here:
https://gitweb.torproject.org/tor.git/tree/src/feature/dirauth/dirvote.c#n4630
The required protocols must stay the same, I'll open another ticket for
them.
