+ o Minor bugfixes (log message reduction)
+   - Fix a path state issue that triggered a notice during relay startup.
+     Fixes bug #8320; bugfix on 0.2.4.10-alpha.
+   - Reduce occurrences of warns about circuit purpose in
+     connection_ap_expire_building(). Fixes bug #8477; bugfix on
+     0.2.4.11-alpha.
+   - Fix a directory authority warn caused when we have a large amount
+     of badexit bandwidth.  Fixes bug #8419; bugfix on 0.2.2.10-alpha.
+   - Reduce a path bias length check notice log to info. The notice
+     is triggered when creating controller circuits. Fixes bug #8196;
+     bugfix on 0.2.4.8-alpha.
