+  o Minor bugfixes (logging):
+    - If we encounter a bug when flushing a buffer to a TLS connection,
+      only log the bug once per invocation of the Tor process.  Previously we
+      would log with every occurrence, which could cause us to run out of
+      disk space.  Fixes bug 33093; bugfix on 0.3.2.2-alpha.
