Changes in version 0.2.1.31 - 2011-05-??
+ Tor 0.2.1.31 fixes a variety of potential privacy problems.
+
o Security/privacy fixes (also included in 0.2.2.x):
+ - Replace all potentially sensitive memory comparison operations
+ with versions whose runtime does not depend on the data being
+ compared. This will help resist a class of attacks where an
+ adversary can use variations in timing information to learn
+ sensitive data. Fix for one case of bug 3122. (Safe memcmp
+ implementation by Robert Ransom based partially on code by DJB.)
+ - When receiving a hidden service descriptor, check that it is for
+ the hidden service we wanted. Previously, Tor would store any
+ hidden service descriptors that a directory gave it, whether it
+ wanted them or not. This wouldn't have let an attacker impersonate
+ a hidden service, but it did let directories pre-seed a client
+ with descriptors that it didn't want. Bugfix on 0.0.6.
- Avoid linkability based on cached hidden service descriptors: forget
all hidden service descriptors cached as a client when processing a
SIGNAL NEWNYM command. Fixes bug 3000; bugfix on 0.0.6.

- Fix an assert in parsing router descriptors containing IPv6

somebody tried some experimental code. Bugfix on 0.2.1.3-alpha.
