 fwknop-2.6.3 (05//2014):
-    - [server] Bug fix to handle SPA packets over HTTP by making sure to honor
-      the ENABLE_SPA_OVER_HTTP fwknopd.conf variable and to properly account
-      for SPA packet lengths when delivered via HTTP.
-    - [server] Add --test mode to instruct fwknopd to acquire and process
-      SPA packets, but not manipulate firewall rules or execute commands that
-      are provided by SPA clients. This option is mostly useful for the fuzzing
-      tests in the test suite to ensure broad code coverage under adverse
-      conditions.
-    - [server] Bug fix for PF firewalls without ALTQ support on FreeBSD. With
-      this fix it doesn't matter whether ALTQ support is available or not.
-      Thanks to Barry Allard for discovering and reporting this issue.
-      Closes issue #121 on github.
+    - Integrated the 'libfiu' fault injection library available from
+      http://blitiri.com.ar/p/libfiu/  This feature is disabled by default,
+      and requires the --enable-libfiu-support argument to the 'configure'
+      script in order to enable it. With fwknop compiled against libfiu, fault
+      injections are done at various locations within the fwknop sources and
+      the test suite verifies that the faults are properly handled at run time
+      via test/fko-wrapper/fko_fault_injection.c. In addition, the libfiu tool
+      'fiu-run' is used against the fwknop binaries to ensure they handle
+      faults that libfiu introduces into libc functions. For example, fiu-run
+      can force malloc() to fail even without huge memory pressure on the
+      local system, and the test suite ensures the fwknop binaries properly
+      handle this.
+    - [test suite] Integrated a new python fuzzer for fwknop SPA packets (see
+      test/spa_fuzzing.py). This greatly extends the ability of the test suite
+      to validate libfko operations since SPA fuzzing packets are sent through
+      libfko routines directly (indendepently of encryption and
+      authentication) with a special 'configure' option
+      --enable-fuzzing-interfaces. The python fuzzer generates over 300K SPA
+      packets, and when used by the test suite consumes about 400MB of disk.
+      For reference, to use both the libfiu fault injection feature mentioned
+      above and the python fuzzer, use the --enable-complete option to the
+      test suite.
     - [server] Add a new GPG_FINGERPRINT_ID variable to the access.conf file
       so that full GnuPG fingerprints can be required for incoming SPA packets
       in addition to the appreviated GnuPG signatures listed in GPG_REMOTE_ID.
