+Changes in version 0.1.2.19 - 2008-01-17
+  Tor 0.1.2.19 fixes a huge memory leak on exit relays, makes the default
+  exit policy a little bit more conservative so it's safer to run an
+  exit relay on a home system, and fixes a variety of smaller issues.
+
+  o Security fixes:
+    - Exit policies now reject connections that are addressed to a
+      relay's public (external) IP address too, unless
+      ExitPolicyRejectPrivate is turned off. We do this because too
+      many relays are running nearby to services that trust them based
+      on network address.
+
+  o Major bugfixes:
+    - When the clock jumps forward a lot, do not allow the bandwidth
+      buckets to become negative. Fixes bug 544.
+    - Fix a memory leak on exit relays; we were leaking a cached_resolve_t
+      on every successful resolve. Reported by Mike Perry.
+    - Purge old entries from the "rephist" database and the hidden
+      service descriptor database even when DirPort is zero.
+    - Stop thinking that 0.1.2.x directory servers can handle "begin_dir"
+      requests. Should ease bugs 406 and 419 where 0.1.2.x relays are
+      crashing or mis-answering these requests.
+    - When we decide to send a 503 response to a request for servers, do
+      not then also send the server descriptors: this defeats the whole
+      purpose. Fixes bug 539.
+
+  o Minor bugfixes:
+    - Changing the ExitPolicyRejectPrivate setting should cause us to
+      rebuild our server descriptor.
+    - Fix handling of hex nicknames when answering controller requests for
+      networkstatus by name, or when deciding whether to warn about
+      unknown routers in a config option. (Patch from mwenge.)
+    - Fix a couple of hard-to-trigger autoconf problems that could result
+      in really weird results on platforms whose sys/types.h files define
+      nonstandard integer types.
+    - Don't try to create the datadir when running --verify-config or
+      --hash-password. Resolves bug 540.
+    - If we were having problems getting a particular descriptor from the
+      directory caches, and then we learned about a new descriptor for
+      that router, we weren't resetting our failure count. Reported
+      by lodger.
+    - Although we fixed bug 539 (where servers would send HTTP status 503
+      responses _and_ send a body too), there are still servers out there
+      that haven't upgraded. Therefore, make clients parse such bodies
+      when they receive them.
+    - Run correctly on systems where rlim_t is larger than unsigned long.
+      This includes some 64-bit systems.
+    - Run correctly on platforms (like some versions of OS X 10.5) where
+      the real limit for number of open files is OPEN_FILES, not rlim_max
+      from getrlimit(RLIMIT_NOFILES).
+    - Avoid a spurious free on base64 failure.
+    - Avoid segfaults on certain complex invocations of
+      router_get_by_hexdigest().
+    - Fix rare bug on REDIRECTSTREAM control command when called with no
+      port set: it could erroneously report an error when none had
+      happened.
+

 Changes in version 0.1.2.18 - 2007-10-28
   Tor 0.1.2.18 fixes many problems including crash bugs, problems with
   hidden service introduction that were causing huge delays, and a big
