       whether they may be resurrected for the 1.9 series. If you don't
       know what it means, just ignore this note.

+    o	added run.Rserve(background=TRUE) mode which meshes server
+	processing loop (i.e., the loop which accepts new connections)
+	and the R session event loop. The function returns as soon
+	as all the server ports are bound (essentailly immediately).
+	This allows the server R process to run R code in the main
+	session after the server was started and thus influence future
+	client connections. This is currently only supported on unix.
+
+	Please note that any changes to the server R session only
+	affect new connections, not existing ones.
+
+	If a function .Rserve.served is defined in the global
+	environment then it will be called after each new accepted
+	client connection in the main R session.
+
+	Function stop.Rserve() can be used to stop and remove all
+	servers started with run.Rserve(). Note that all existing
+	client connections will remain intact.
+
+	NB: This functionality is currently considered experimental
+	and the return value is undefined (currently TRUE on success,
+	but may return other information in the future to enable more
+	fine-grained control over the background servers).

     o	Windows: use pkg-config if available (many thanks to Tomas
 	Kalibera for the work on the toolchain!)
