 Changes in version 0.2.3.12-alpha - 2012-02-??
   o Major bugfixes:
+    - Fix building when the path to sed, openssl or sha1sum contains
+      spaces, which is pretty common on Windows. Fixes bug 5065; bugfix
+      on 0.2.2.1-alpha.
     - Set the SO_REUSEADDR socket option before we call bind() on outgoing
       connections. This change should allow busy exit relays to stop
       running out of available sockets as quickly. Fixes bug 4950;

       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,
+      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

       to info: people kept mistaking it for a real problem, whereas it
       is seldom the problem even when we are failing to bootstrap. Fixes
       bug 5067; bugfix on 0.2.0.10-alpha.
+    - Don't put "TOR_PT_EXTENDED_SERVER_PORT=127.0.0.1:4200" in a
+      managed pluggable transport server proxy's environment.
+      Previously, we would put it there, even though Tor doesn't
+      implement an 'extended server port' yet, and even though Tor
+      almost certainly isn't listening to that address. Bugfix on
+      0.2.3.6-alpha.
     - Actually log the heartbeat message every HeartbeatPeriod seconds,
       not every HeartbeatPeriod + 1 seconds. Fixes bug 4942; bugfix on
       0.2.3.1-alpha. Bug reported by Scott Bennett.
