Changes in version 0.2.3.8-alpha - 2011-11-21
Changes in version 0.2.3.8-alpha - 2011-11-22
Tor 0.2.3.8-alpha fixes some crash and assert bugs, including a
socketpair-related bug that has been bothering Windows users. It adds
support to serve microdescriptors to controllers, so Vidalia's network
map can resume listing relays (once Vidalia implements its side),
and adds better support for hardware AES acceleration. Finally, it
starts the process of adjusting the bandwidth cutoff for getting the
"Fast" flag from 20KB to (currently) 32KB -- preliminary results show
that tiny relays harm performance more than they help network capacity.
o Major bugfixes:
- Initialize Libevent with the EVENT_BASE_FLAG_NOLOCK flag enabled, so
that it doesn't attempt to allocate a socketpair. This could cause

allocation (and then assert) for hidden service introduction
point decryption. Bug discovered by Dan Rosenberg. Fixes bug 4410;
bugfix on 0.2.1.5-alpha.
- Remove the artificially low cutoff of 20KB to guarantee the Fast
flag. In the past few years the average relay speed has picked
up, and while the "top 7/8 of the network get the Fast flag" and
"all relays with 20KB or more of capacity get the Fast flag" rules
used to have the same result, now the top 7/8 of the network has
a capacity more like 32KB. Bugfix on 0.2.1.14-rc. Fixes bug 4489.
- Fix a rare assertion failure when checking whether a v0 hidden
service descriptor has any usable introduction points left, and
we don't have enough information to build a circuit to the first
