Tor 0.2.2.13-alpha addresses the recent connection and memory overload<br>
problems we've been seeing on relays, especially relays with their DirPort<br>
open. If your relay has been crashing, or you turned it off because it<br>
used too many resources, give this release a try.<br>

Changes in version 0.2.2.13-alpha - 2010-04-24<br>
 o Major bugfixes:<br>
  - Teach relays to defend themselves from connection overload. Relays<br>
   now close idle circuits early if it looks like they were intended<br>
   for directory fetches. Relays are also more aggressive about closing<br>
   TLS connections that have no circuits on them. Such circuits are<br>
   unlikely to be re-used, and tens of thousands of them were piling<br>
   up at the fast relays, causing the relays to run out of sockets<br>
   and memory. Bugfix on 0.2.0.22-rc (where clients started tunneling<br>
   their directory fetches over TLS).<br>
<br>
 o Minor features:<br>
  - Finally get rid of the deprecated and now harmful notion of "clique<br>
   mode", where directory authorities maintain TLS connections to<br>
   every other relay.<br>
  - Directory authorities now do an immediate reachability check as soon<br>
   as they hear about a new relay. This change should slightly reduce<br>
   the time between setting up a relay and getting listed as running<br>
   in the consensus. It should also improve the time between setting<br>
   up a bridge and seeing use by bridge users.<br>
  - Directory authorities no longer launch a TLS connection to every<br>
   relay as they startup. Now that we have 2k+ descriptors cached,<br>
   the resulting network hiccup is becoming a burden. Besides,<br>
   authorities already avoid voting about Running for the first half<br>
   hour of their uptime.<br>
