+  * GH-1252: rename files with colons for Windows compatibility (Jon Siwek, Corelight)
+
+    A short-term measure so that the Zeek source tree can simply exist on a
+    Windows filesystem.  For true support, the logic that decides/generates
+    the filename format will need to change.
+
+  * Use std::function instead of a function pointer in packet_analysis::Component (Tim Wojtulewicz, Corelight)
