o Major features:

- Directory authorities can now create, vote on, and serve multiple
parallel formats of directory data as part of their voting process.
This is a partial implementation of Proposal 162: "Publish the
consensus in multiple flavors."
- Directory authorities can now agree on and publish small summaries of
router information that clients can use in place of regular server
descriptors. This will eventually allow clients to use far less
bandwidth for downloading information about the network. This begins
the implementation of of Proposal 158: "Clients download a consensus +
Microdescriptors".

- The directory voting system is now extensible to use multiple hash
algorithms for signatures and resource selection. Newer formats are
signed with SHA256, with a possibility for moving to a better hash
algorithm in the future.

- New DisableAllSwap option. If set to 1, Tor will attempt to lock all
current and future memory pages. On supported platforms, this should
effectively disable any and all attempts to page out memory. Under the
hood, DisableAllSwap uses mlockall() on unix-like platforms. Windows is
currently unsupported. We believe that this feature works on modern
Gnu/Linux distributions. Mac OS X appears to be broken by design. On
reasonable *BSD systems it should also be supported but this is untested.
This option requires that you start your Tor as root. If you use
DisableAllSwap, please consider using the User option to properly reduce
the privileges of your Tor.

- Numerous changes, bugfixes, and workarounds from Nathan Freitas
to help Tor build correctly for Android phones.
o Major bugfixes:
- Work around a security feature in OpenSSL 0.9.8l that prevents our
handshake from working unless we explicitly tell OpenSSL that we are
using SSL renegotiation safely. We are, of course, but OpenSSL
0.9.8l won't work unless we say we are.
o Code simplifications and refactorings:
- Numerous changes, bugfixes, and workarounds from Nathan Freitas
to help Tor build correctly for Android phones.
- Begun converting Tor's signature and message digest logic to handle
multiple hash algorithms.

o Minor bugfixes:
- Fix a crash bug when trying to initialize the evdns module in
Libevent 2.
Libevent 2. Bugfix on 0.2.1.16-rc.
- Stop logging at severity 'warn' when some other Tor client tries
to establish a circuit with us using weak DH keys. It's a protocol
violation, but that doesn't mean ordinary users need to hear about

- If your relay can't keep up with the number of incoming create
cells, it would log one warning per failure into your logs. Limit
warnings to 1 per minute. Bugfix on 0.0.2pre10; fixes bug 1042.
- Bridges do not use the default exit policy, but reject *:* by
default. Fixes bug 1113.
- Bridges now use "reject *:*" as their default exit policy. Bugfix
on 0.2.0.3-alpha; fixes bug 1113.
- Fix a memory leak on directory authorities during voting that was
introduced in 0.2.2.1-alpha. Found via valgrind.
