revno: 2476.423.26
committer: kostja@bodhi.(none)
timestamp: Tue 2007-10-16 20:12:37 +0400
message:

  (this is a backward-compatible change).

revno: 2476.785.22
committer: kostja@bodhi.(none)
timestamp: Tue 2007-10-16 19:37:25 +0400
message:
  Remove some remains of support of 3.22 protocol. This was in fact dead code,
  since the option to talk 3.22 protocol was removed in 4.1 and there
  is no other protocol negotiation mechanism besides this option.
