+  o Minor bug fixes:
+    - If any directory created by Tor is marked as group readable, the
+      filesystem group is allowed to be either the default GID or the root
+      user. Allowing root to read the DataDirectory prevents the need for
+      CAP_READ_SEARCH when using systemd's CapabilityBoundingSet, or
+      dac_read_search when using SELinux.
