+   Added the ``td_agent_log_rotate_size`` parameter to Fluentd
+
+features:
+  - |
+    Added the capability to specify the log rotation size for Fluentd
+    ``td-agent`` using the ``td_agent_log_rotate_size`` parameter. This prevents a
+    single log file from taking too much disk space. This parameter is set to
+    10 MB by default.
