+Changes in version 0.2.3.25 - 2012-11-19
+ The Tor 0.2.3 release series is dedicated to the memory of Len "rabbi"
+ Sassaman (1980-2011), a long-time cypherpunk, anonymity researcher,
+ Mixmaster maintainer, Pynchon Gate co-designer, CodeCon organizer,
+ programmer, and friend. Unstinting in his dedication to the cause of
+ freedom, he inspired and helped many of us as we began our work on
+ anonymity, and inspires us still. Please honor his memory by writing
+ software to protect people's freedoms, and by helping others to do so.
+
+ Tor 0.2.3.25, the first stable release in the 0.2.3 branch, features
+ significantly reduced directory overhead (via microdescriptors),
+ enormous crypto performance improvements for fast relays on new
+ enough hardware, a new v3 TLS handshake protocol that can better
+ resist fingerprinting, support for protocol obfuscation plugins (aka
+ pluggable transports), better scalability for hidden services, IPv6
+ support for bridges, performance improvements like allowing clients
+ to skip the first round-trip on the circuit ("optimistic data") and
+ refilling token buckets more often, a new "stream isolation" design
+ to isolate different applications on different circuits, and many
+ stability, security, and privacy fixes.
+
+ o Major bugfixes:
+ - Tor tries to wipe potentially sensitive data after using it, so
+ that if some subsequent security failure exposes Tor's memory,
+ the damage will be limited. But we had a bug where the compiler
+ was eliminating these wipe operations when it decided that the
+ memory was no longer visible to a (correctly running) program,
+ hence defeating our attempt at defense in depth. We fix that
+ by using OpenSSL's OPENSSL_cleanse() operation, which a compiler
+ is unlikely to optimize away. Future versions of Tor may use
+ a less ridiculously heavy approach for this. Fixes bug 7352.
+ Reported in an article by Andrey Karpov.
+
+ o Minor bugfixes:
+ - Fix a harmless bug when opting against publishing a relay descriptor
+ because DisableNetwork is set. Fixes bug 7464; bugfix on
+ 0.2.3.9-alpha.
