+Changes in version 0.2.4.3-alpha - 2012-09-??
+ o Security fixes:
+ - Fix an assertion failure in tor_timegm() that could be triggered
+ by a badly formatted directory object. Bug found by fuzzing with
+ Radamsa. Fixes bug 6811; bugfix on 0.2.0.20-rc.
+
+ o Major bugfixes:
+ - Fix a possible crash bug when checking for deactivated circuits
+ in connection_or_flush_from_first_active_circuit(). Fixes bug 6341;
+ bugfix on 0.2.2.7-alpha. Bug report and fix received pseudonymously.
+ - Allow routers to detect that their own DirPorts are running. When
+ we removed support for versions_supports_begindir, we also
+ accidentally removed the mechanism we used to self-test our
+ DirPort. Diagnosed with help from kargig. Fixes bugs 6814 and 6815;
+ bugfix on 0.2.4.2-alpha.
+
+ o Security features:
+ - Switch to a completely time-invariant approach for picking nodes
+ weighted by bandwidth. Our old approach would run through the
+ part of the loop after it had made its choice slightly slower
+ than it ran through the part of the loop before it had made its
+ choice. Addresses ticket 6538.
+
+ o Minor bugfixes:
+ - Correct file sizes when reading binary files on Cygwin, to avoid
+ a bug where Tor would fail to read its state file. Fixes bug 6844;
+ bugfix on 0.1.2.7-alpha.
+ - Fix round_to_power_of_2() so it doesn't invoke undefined behavior
+ with large values. This situation was untriggered, but nevertheless
+ incorrect. Fixes bug 6831; bugfix on 0.2.0.1-alpha.
+ - Reject consensus votes with more than 64 known-flags. We aren't even
+ close to that limit yet, and our code doesn't handle it correctly.
+ Fixes bug 6833; bugfix on 0.2.0.1-alpha.
+ - Avoid undefined behaviour when parsing the list of supported
+ rendezvous/introduction protocols in a hidden service descriptor.
+ Previously, Tor would have confused (as-yet-unused) protocol version
+ numbers greater than 32 with lower ones on many platforms. Fixes
+ bug 6827; bugfix on 0.2.0.10-alpha. Found by George Kadianakis.
+ - Fix building with older versions of GCC that don't like preprocessor
+ directives inside macro arguments. Found by grarpamp. Fixes bug
+ 6842; bugfix on 0.2.4.2-alpha.
+ - Switch weighted node selection rule from using a list of doubles
+ to using a list of int64_t. This change should make the process
+ slightly easier to debug and maintain. Needed to finish ticket 6538.
+
+ o Code simplification and refactoring:
+ - Move the generic "config" code into a new file, and have "config.c"
+ hold only torrc- and state-related code. Resolves ticket 6823.
+ - Move the core of our "choose a weighted element at random" logic
+ into its own function, and give it unit tests. Now the logic is
+ testable, and a little less fragile too.
+
+ o Documentation fixes:
+ - Resolve a typo in torrc.sample.in. Fixes bug 6819; bugfix on
+ 0.2.3.14-alpha.
