+Changes in version 0.2.2.30-rc - 2011-07-07
+  Tor 0.2.2.30-rc is the first release candidate for the Tor 0.2.2.x
+  series. It fixes a few smaller bugs, but generally appears stable.
+  Please test it and let us know whether it is!
+
+  o Minor bugfixes:
+    - Send a SUCCEEDED stream event to the controller when a reverse
+      resolve succeeded. Fixes bug 3536; bugfix on 0.0.8pre1. Issue
+      discovered by katmagic.
+    - Always NUL-terminate the sun_path field of a sockaddr_un before
+      passing it to the kernel. (Not a security issue: kernels are
+      smart enough to reject bad sockaddr_uns.) Found by Coverity;
+      CID #428. Bugfix on Tor 0.2.0.3-alpha.
+    - Don't stack-allocate the list of supplementary GIDs when we're
+      about to log them. Stack-allocating NGROUPS_MAX gid_t elements
+      could take up to 256K, which is way too much stack. Found by
+      Coverity; CID #450. Bugfix on 0.2.1.7-alpha.
+    - Add BUILDTIMEOUT_SET to the list returned by the 'GETINFO
+      events/names' control-port command. Bugfix on 0.2.2.9-alpha;
+      fixes part of bug 3465.
+    - Fix a memory leak when receiving a descriptor for a hidden
+      service we didn't ask for. Found by Coverity; CID #30. Bugfix
+      on 0.2.2.26-beta.
+
+  o Minor features:
+    - Update to the July 1 2011 Maxmind GeoLite Country database.
