+Changes in version 0.2.4.1-alpha - 2012-09-05
+ Tor 0.2.4.1-alpha adds ... XXX
+
+ This is the first alpha release in a new series, so expect there to
+ be bugs. Users who would rather test out a more stable branch should
+ stay with 0.2.3.x for now.
+
+ o Major features (bridges):
+ - Bridges now report the pluggable transports they support to the
+ bridge authority, so it can pass the supported transports on to
+ bridgedb and/or eventually do reachability testing. Implements
+ ticket 3589.
+
+ o Major features (IPv6):
+ - Bridge authorities now accept IPv6 bridge addresses and include
+ them in network status documents. Implements ticket 5534.
+ - Clients who set "ClientUseIPv6 1" may connect to entry nodes over
+ IPv6. Set "ClientPreferIPv6ORPort 1" to make this even more likely
+ to happen. Implements ticket 5535.
+ - All kind of relays, not just bridges, can now advertise an IPv6
+ OR port. Implements ticket 6362.
+ - Directory authorities vote on IPv6 OR ports using the new consensus
+ method 14. Implements ticket 6363.
+
+ o Major features (build):
+ - Switch to a nonrecursive Makefile structure. Now instead of each
+ Makefile.am invoking other Makefile.am's, there is a master
+ Makefile.am that includes the others. This change makes our build
+ process slightly more maintainable, and improves parallelism for
+ building with make -j. Original patch by Stewart Smith; various
+ fixes by Jim Meyering.
+ - Where available, we now use automake's "silent" make rules by
+ default, so that warnings are easier to spot. You can get the old
+ behavior with "make V=1". Patch by Stewart Smith for ticket 6522.
+
+ o Minor features (code security and spec conformance):
+ - Clear keys and key-derived material left on the stack in
+ rendservice.c and rendclient.c. Check return value of
+ crypto_pk_write_private_key_to_string() in end_service_load_keys().
+ These fixes should make us more forward-secure against cold-boot
+ attacks and the like. Fixes bug 2385.
+ - Reject EXTEND cells sent to nonexistent streams. According to the
+ spec, an EXTEND cell sent to _any_ nonzero stream ID is invalid, but
+ we were only checking for stream IDs that were currently in use.
+ Found while hunting for more instances of bug 6271. Bugfix on
+ 0.0.2pre8, which introduced incremental circuit construction.
+
+ o Minor features (streamlining);
+ - No longer include the "opt" prefix when generating routerinfos
+ or v2 directories: it has been needless since Tor 0.1.2. Closes
+ ticket 5124.
+ - Remove some now-needless code that tried to aggressively flush
+ OR connections as data was added to them. Since 0.2.0.1-alpha, our
+ cell queue logic has saved us from the failure mode that this code
+ was supposed to prevent. Removing this code will limit the number
+ of baroque control flow paths through Tor's network logic. Reported
+ pseudonymously on IRC. Fixes bug 6468; bugfix on 0.2.0.1-alpha.
+
+ o Minor features (controller):
+ - Add a "GETINFO signal/names" control port command. Implements
+ ticket 3842.
+ - Provide default values for all options via "GETINFO config/defaults".
+ Implements ticket 4971.
+
+ o Minor features (IPv6):
+ - New config option "AuthDirHasIPv6Connectivity auto" that ... XXX
+ Implements feature 5974.
+ - A relay with an IPv6 OR port now sends that address in NETINFO
+ cells (in addition to its other address). Implements ticket 6364.
+ - New config option AuthDirPublishIPv6. Implements ticket 6406.
+
+ o Minor features (log messages):
+ - Omit the first heartbeat log message, because it never has anything
+ useful to say, and it clutters up the bootstrapping messages.
+ Resolves ticket 6758.
+ - Don't log about reloading the microdescriptor cache at startup. Our
+ bootstrap warnings are supposed to tell the user when there's a
+ problem, and our bootstrap notices say when there isn't. Resolves
+ ticket 6759; bugfix on 0.2.2.6-alpha.
+ - Don't log "I learned some more directory information" when we're
+ reading cached directory information. Reserve it for when new
+ directory information arrives in response to a fetch. Resolves
+ ticket 6760.
+ - Prevent rounding error in path bias counts when scaling
+ them down, and use the correct scale factor default. Also demote
+ some path bias related log messages down a level and make others
+ less scary sounding. Fixes bug 6647. Bugfix against 0.2.3.17-beta.
+ - We no longer warn so much when generating manpages from their
+ asciidoc source.
+
+ o Code simplifications and refactoring:
+ - Enhance our internal sscanf replacement so that we can eliminate
+ the last remaining uses of the system sscanf. (Though those uses
+ of sscanf were safe, sscanf itself is generally error prone, so
+ we want to eliminate when we can.) Fixes ticket 4195 and Coverity
+ CID 448.
+ - Move ipv6_preferred from routerinfo_t to node_t. Addresses bug 4620.
+ - Move last_reachable and testing_since from routerinfo_t to node_t.
+ Implements ticket 5529.
+ - Add replaycache_t structure, functions and unit tests, then refactor
+ rend_service_introduce() to be more clear to read, improve, debug,
+ and test. Resolves bug 6177.
+ - Finally remove support for malloc_good_size and malloc_usable_size.
+ We had hoped that these functions would let us eke a little more
+ memory out of our malloc implementation. Unfortunately, the only
+ implementations that provided these functions are also ones that
+ are already efficient about not overallocation: they never got us
+ more than 7 or so bytes per allocation. Removing them saves us a
+ little code complexity and a nontrivial amount of build complexity.
+
+ o New requirements:
+ - Tor maintainers now require Automake version 1.9 or later to build
+ Tor from the Git repository. (Automake is not required when building
+ from a source distribution.)
+
+
Changes in version 0.2.3.21-rc - 2012-09-05
Tor 0.2.3.21-rc is the fourth release candidate for the Tor 0.2.3.x
series. It fixes a trio of potential security bugs, fixes a bug where
