Changes in version 0.2.5.5-alpha - 2014-06-1?
Tor 0.2.5.5-alpha fixes a wide variety of remaining issues in the Tor
0.2.5.x release series, including a couple of DoS issues, some
performance regressions, a large number of bugs affecting the
Linux seccomp2 sandbox code, and various other bugfixes. It also adds
performance regressions, a large number of bugs affecting the Linux
seccomp2 sandbox code, and various other bugfixes. It also adds
diagnostic bugfixes for a few tricky issues that we're trying to
track down.

sent over the connection, regardless of the target of the
connection. Now, we randomize the intervals by adding up to 50% of
their base value, we measure the length of time since connection
last had at least one circuit, and we allow connections to
known ORs to remain open a little longer (15 minutes instead of 3
last had at least one circuit, and we allow connections to known
ORs to remain open a little longer (15 minutes instead of 3
minutes minimum). These changes should improve Tor's resistance
against some kinds of traffic analysis, and lower some overhead
from needlessly closed connections. Fixes ticket 6799.

o Major bugfixes (relay):
- Use a direct dirport connection when uploading non-anonymous

relays would incorrectly use tunnel connections under a fairly
wide variety of circumstances. Fixes bug 11469; bugfix

o Minor bugfixes (performance):
- Avoid a bug where every successful connection made us recompute
the flag telling us whether we have sufficient information to
build circuits. Previously, we would forget our cached value whenever we
successfully opened a channel (or marked a router as running or
not running for any other reason), regardless of whether we had
previously believed the router to be running. This forced us to
run an expensive update operation far too often. Fixes bug 12170;

- Avoid using tor_memeq() for checking relay cell integrity. This
removes a possible performance bottleneck. Fixes part of bug
