  1. o Major features (traffic analysis resistance):
  2. - Relays and clients will now send a padding cell on idle OR
  3. connections every 1.5 to 9.5 seconds (tunable via consensus
  4. parameters). Directory connections and inter-relay connections
  5. are not padded. Padding is negotiated using Tor's link protocol,
  6. so both relays and clients must upgrade for this to take effect.
  7. Clients may still send padding despite the relay's version by
  8. setting ConnectionPadding 1 in torrc, and may disable padding
  9. by setting ConnectionPadding 0 in torrc. Padding may be minimized
  10. for mobile users with the torrc option ReducedConnectionPadding.
  11. Implements Proposal 251 and Section 2 of Proposal 254; closes ticket
  12. 16861.
  13. - Relays will publish 24 hour totals of padding and non-padding cell
  14. counts to their extra-info descriptors, unless PaddingStatistics 0
  15. is set in torrc. These 24 hour totals are also rounded to multiples
  16. of 10000.
