+  o Build changes
+    - Our build system requires automake 1.6 or later to create the
+      Makefile.in files.  Previously, you could have used 1.4.
+      This only affects developers and people building Tor from git;
+      people who build Tor from the source distribution without changing
+      the Makefile.am files should be fine.
