+  o Major bugfixes (hidden service v3):
+    - Make onion service always use the exact amount of configured intro points
+      (or less due to node exlusion). Before, a service could sometimes pick
+      more intro points than configured with the
+      HiddenServiceNumIntroductionPoints option. Fixes bug 31548; bugfix on
+      0.3.2.1-alpha.
