@ -2,42 +2,40 @@ Changes in version 0.2.6.2-alpha - 2014-12-??
Tor 0.2.6.2-alpha is the second alpha release in the 0.2.6.x series.
o Major features (relay, infrastructure):
- Completely revision of the code that relays use to decide which
cell to send next. Formerly, we selected the best circuit to write
on each channel, but we didn't select among channels in any
sophisticated way. Now, we choose the best circuits globally from
among those whose channels are ready to deliver traffic.

This patch implements a new inter-cmux comparison API, a global high/low
watermark mechanism and a global scheduler loop for transmission
prioritization across all channels as well as among circuits on
one channel. This schedule is currently tuned to (tolerantly)
avoid making changes in the current network performance, but it
should form the basis for major circuit performance increases.
Code by Andrea; tuning by Rob Jansen; implements ticket 9262.

o Major features (hidden services):
- Add a HiddenServiceStatistics option that allows Tor relays to
gather and publish statistics the overall size and volume of hidden
service usage.
Specifically, when this option is turned on, an HSDir will publish
an approximate number of hidden services that have published
descriptors to it the past 24 hours. Also, if a relay has acted as
a hidden service rendezvous point, it will publish the approximate
amount of rendezvous cells it has relayed the past 24 hours. The
statistics themselves are obfuscated so that the exact values
cannot be derived. For more details see proposal 238, "Better
hidden service stats from Tor relays". This feature is currently
disabled by default. Implements feature 13192.

o Major bugfixes (hidden services):
- When closing an introduction circuit that was opened in parallel with
others,
don't mark the introduction point as unreachable. Previously, the
first successful connection to an introduction point would make
the other introduction points get marked as having timed out.
Fixes bug 13698; bugfix on 0.0.6rc2.

o Minor bugfixes (misc):
- Stop allowing invalid address patterns like "*/24" that contain both a wildcard
address and a bit prefix length. This
affects all our address-range parsing code. Fixes bug 7484; bugfix on 0.0.2pre14.
