changes/all_descs

-  o Major bugfixes (bridge authority)
-    - Do not allow encrypte requests for "all" bridges to return all
-      bridges.
-

changes/annotations_fix

-  o Major bugfixes
-    - Do even more to reject (and not just ignore) annotations on
-      router descriptors received anywhere but from the cache.
-      Previously we would ignore such annotations at first, but cache
-      them to disk anyway.  Bugfix on 0.2.0.8-alpha. Found by piebeer.
-
-  o Minor bugfixes
-    - Enforce multiplicity rules when parsing annotations.  Bugfix on
-      0.2.0.8-alpha. Found by piebeer.
-

changes/bug1074-part2

-  o Major bugfixes:
-    - Stop sending a CLOCK_SKEW controller status event whenever
-      we fetch directory information from a relay that has a wrong clock.
-      Instead, only inform the controller when it's a trusted authority
-      that claims our clock is wrong. Bugfix on tor-0.1.2.6-alpha;
-      fixes the other half of bug 1074.

changes/bug1125

-  o Major bugfixes
-    - Do not log messages to the controller while shrinking buffer
-      freelists.  Doing so would sometimes make the controller
-      connection try to allocate a buffer chunk, which would mess
-      up the internals of the freelist and cause an assertion
-      failure. Fixes bug 1125; fixed by Robert Ransom. Bugfix on
-      Tor 0.2.0.16-alpha.
-

changes/bug1141

-  o Minor bugfixes:
-    - Fix an assertion failure that could occur in caches or bridge users
-      when using a very short voting interval on a testing network.
-      Diagnosed by Robert Hogan.  Fixes bug 1141; bugfix on 0.2.0.8-alpha.
-

changes/bug1172

-  o Minor bugfixes:
-    - When we restart our relay, we might get a successful connection
-      from the outside before we've started our reachability tests,
-      triggering a warning: "ORPort found reachable, but I have no
-      routerinfo yet. Failing to inform controller of success." This
-      bug was harmless unless Tor is running under a controller
-      like Vidalia, in which case the controller would never get a
-      REACHABILITY_SUCCEEDED status event. Bugfix on 0.1.2.6-alpha;
-      fixes bug 1172.

changes/bug1840

-  o Minor bugfixes:
-    - Allow handshaking OR connections to take a full KeepalivePeriod
-      seconds to handshake.  Previously, we would close them after
-      IDLE_OR_CONN_TIMEOUT seconds, as if they were open.  This is a
-      bugfix on 0.2.1.26.  Thanks to mingw-san for analysis help.  Fixes
-      bug 1840.
-

changes/bug1859

-  o Minor bugfixes:
-    - Bring the logic that gathers routerinfos and assesses the
-      acceptability of circuits into line. This prevents a Tor OP from getting
-      locked in a cycle of choosing its local OR as an exit for a path (due to
-      a .exit request) and then rejecting the circuit because its OR is not
-      listed yet. Also prevent Tor clients from using an OR running in the same
-      instance as an exit (due to a .exit request) if the OR does not meet the
-      same requirements expected of an OR running elsewhere.
-      Fixes bug 1859; bugfix on 0.2.0-alpha.

changes/bug1981

-  o Major bugfixes:
-    - When you use bridges and your network goes away and your bridges
-      get marked as down, recover when you attempt a new socks connection
-      (if the network is back) rather than waiting up to an hour to try
-      fetching new descriptors for your bridges. Bugfix on 0.2.0.3-alpha;
-      fixes bug 1981.

changes/bug2050

-  o Major bugfixes:
-    - Learn our external IP address when we're a relay or bridge, even if
-      we set PublishServerDescriptor to 0. Bugfix on 0.2.0.3-alpha,
-      where we introduced bridge relays that don't need to publish to
-      be useful. Fixes bug 2050.

changes/bug2190

-  o Minor bugfixes
-    - Prevent calls from Libevent from inside Libevent log handlers.
-      This had potential to cause a nasty set of crashes, especially if
-      running Libevent with debug logging enabled, and running Tor
-      with a controller watching for low-severity log messages.
-      Bugfix on 0.1.0.2-rc.  Fixes bug 2190.

changes/bug2305

-  o Build changes
-    - Tor does not build packages correctly with Automake 1.6 and earlier;
-      added a check to Makefile.am to make sure that we're building with
-      Automake 1.7 or later.
-

changes/bug2313

-  o Minor bugfixes
-    - Fix compilation on mingw when a pthreads compatibility library
-      has been installed.  (We don't want to use it, so we shouldn't
-      be including pthread.h.)  Fixes bug 2313; bugfix on 0.1.0.1-rc.

changes/bug2324

-  o Minor bugfixes
-    - Add a check for SIZE_T_MAX to tor_realloc to try to avoid
-      underflow errors there too.  Fixes bug 2324.
-

changes/bug2324_uncompress

-  o Major bugfixes (security):
-    - Prevent a DoS attack by disallowing any zlib-compressed data
-      whose compression factor is implausibly high.  Fixes the
-      second part of bug2324; found by doors.
-

changes/bug2326

-  o Minor bugfixes
-    - Fix a bug where we would assert if we ever had a
-      cached-descriptors.new file (or another file read directly into
-      memory) of exactly SIZE_T_CEILING bytes.  Found by doors; fixes
-      bug 2326; bugfix on 0.2.1.25.
-

changes/bug2328

-  o Minor bugfixes
-    - Fix a bug where we would declare that we had run out of virtual
-      addresses when the address space was only half-exhausted.  Bugfix
-      on 0.1.2.1-alpha.
-    - Correctly handle the case where AutomapHostsOnResolve is set but no
-      virtual addresses are available.  Fixes bug2328, bugfix on
-      0.1.2.1-alpha.  Bug found by doorss.
-    - Correctly handle wrapping around to when we run out of virtual address
-      space.  Found by cypherpunks, bugfix on 0.2.0.5-alpha.

changes/bug2332

-  o Minor bugfixes
-    - Fix a bug with handling misformed replies to reverse DNS lookup
-      requests in DNSPort.  Bugfix on Tor 0.2.0.1-alpha.  Related to a bug
-      reported by doorss.

changes/bug2352

-  o Minor bugfixes
-    - Fix some potential asserts and partsing issues with grossly
-      malformed router caches.  Fixes bug 2352.  Found by doorss.
-      Bugfix on Tor 0.2.1.27.
-
-

changes/bug2384

-  o Minor bugfixes
-    - Zero out a few more keys in memory before freeing them.  Fixes bug
-      2384 and part of bug 2385.  These key instances found by
-      "cypherpunks".  Bugfix on 0.0.2pre9.
