 #First line must be a semantic version number
 #all other lines are ignored.
+#0.2.1 - treefilenames: filter '.' and '..' by tail in the hidden-directory glob so recursion does not loop on non-Windows platforms
 #0.2.0 - treefilenames now matches hidden files and recurses into hidden directories on all platforms
 #0.2.0 - added PUNKARGS documentation for punk::path::relative
