 Changes in version 0.2.3.12-alpha - 2012-02-13
+  Tor 0.2.3.12-alpha lets fast exit relays scale better, allows clients
+  to use bridges that run Tor 0.2.2.x, and resolves several big bugs
+  when Tor is configured to use a pluggable transport like obfsproxy.
+

       spaces, which is pretty common on Windows. Fixes bug 5065; bugfix

       bugfix on 0.2.2.26-beta.
     - Allow 0.2.3.x clients to use 0.2.2.x bridges. Previously the client
       would ask the bridge for microdescriptors, which are only supported
-      in 0.2.3.x and later, and then fail to bootstrap when it didn't
-      get the answers it wanted. Fixes bug 4013; bugfix on 0.2.3.2-alpha.
-    - Avoid a crash when managed proxies are configured and we receive
-      HUP signals or configuration values too rapidly. This happens most
-      commonly when Vidalia tries to attach to Tor or tries to configure
-      the Tor it's attached to. Fixes bug 5084; bugfix on 0.2.3.6-alpha.
-    - Properly set up obfsproxy's environment in managed mode. The Tor
-      Browser Bundle needs LD_LIBRARY_PATH to be passed to obfsproxy,
+      in 0.2.3.x, and then fail to bootstrap when it didn't get the
+      answers it wanted. Fixes bug 4013; bugfix on 0.2.3.2-alpha.

+    - Properly set up obfsproxy's environment when in managed mode. The
+      Tor Browser Bundle needs LD_LIBRARY_PATH to be passed to obfsproxy,
       and when you run your Tor as a daemon, there's no HOME. Fixes bugs
       5076 and 5082; bugfix on 0.2.3.6-alpha.
 
   o Minor features:
     - Use the dead_strip option when building Tor on OS X. This reduces
       binary size by almost 19% when linking openssl and libevent
-      statically, which we do for TBB.
+      statically, which we do for Tor Browser Bundle.
     - Fix broken URLs in the sample torrc file, and tell readers about
       the OutboundBindAddress, ExitPolicyRejectPrivate, and
       PublishServerDescriptor options. Addresses bug 4652.
