o Minor features:
- CONF_CHANGED event is provided so that controllers can be notified
of any configuration changes made by other controllers/SETCONF/HUP.
Implements #1692.

o Minor features:
- Replace files in stats/ rather than appending to them. Now that we
include statistics in extra-info descriptors, it makes no sense to
keep old statistics forever. Implements #2930.

o Minor bugfixes:
- The "--quiet" and "--hush" options now apply not only to Tor's
behavior before user-configured logs are added, but also to
Tor's behavior in the absense of configured logs. Fixes bug
3550; bugfix on 0.2.0.10-alpha.

o Minor bugfixes:
- Write several files in text mode, on OSes that distinguish text
mode from binary mode (namely, Windows). These files are:
buffer-stats, dirreq-stats, and entry-stats on relays that collect
those statistics; client_keys and hostname files for hidden
services that use authentication; and (in the tor-gencert utility)
newly generated identity and signing keys. Previously, we
wouldn't specify text mode or binary mode, leading to an assertion
failure. Fixes bug 3607. Bugfix on 0.2.1.1-alpha (when the
DirRecordUsageByCountry option which would have triggered the
assertion failure was added), although this assertion failure
would have occurred in tor-gencert on Windows in 0.2.0.1-alpha.

with bufferevents. The warning was caused by someone doing an http
request to a relay's orport. Also don't warn for a few related
non-errors. Fixes bug 3700; bugfix on 0.2.3.1-alpha.

o Major bugfixes (bufferevents):

o Major features:
- When using an exit nodes running 0.2.3.1-alpha and later,
clients can now "optimistically" send data on a stream before
the exit node reports that the stream has opened. This can save
a round trip when starting connections with protocols where the
client speaks first. This behavior is controlled by a (currently
disabled) networkstatus consensus parameter. To turn it on or
off manually, use the "OptimisticData" torrc option. Implements
proposal 181; code by Ian Goldberg.

o Major features:
- You can now configure Tor so that streams from different
applications are isolated on different circuits, to prevent an
attacker who sees your streams leaving an exit node from linking
your sessions to one another. To do this, choose some way to
distinguish the applications -- have them connect to different
SocksPorts, or have one of them use SOCKS4 while the other uses
SOCKS5, or have them pass different authentication strings to
the SOCKS proxy. Then use the new SocksPort syntax to configure
the degree of isolation you need. This implements Proposal 171.
o Minor features:
- There's a new syntax for specifying multiple client ports (such as
SOCKSPort, TransPort, DNSPort, NATDPort): you can now just declare
multiple ...Port entries with full addr:port syntax on each.
The old ...ListenAddress format is still supported, but you can't
mix it with the new SOCKSPort syntax.
o Code simplifications and refactoring:
- Rewrote the listener-selection logic so that parsing which ports
we want to listen on is now separate form binding to the ports
we want.

o Build changes:
- Building Tor with bufferevent support now requires Libevent
2.0.13-stable or later. Previous versions of Libevent had bugs
in SSL-related bufferevents and related issues that would make
Tor work badly with bufferevents. Requiring 2.0.13-stable also
means that Tor with bufferevents can take advantage of Libevent
APIs introduced after 2.0.8-rc.
o Minor bugfixes:
- Use evbuffer_copyout() in inspect_evbuffer(). This fixes a memory
leak, and lets Libevent worry about how to best copy data out
of a buffer.
