@@ -30,11 +30,39 @@ Who:	Adrian Bunk <bunk@stusta.de>
 ---------------------------
 
 What:	raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN
-When:	November 2006
-Why:	Deprecated in favour of the new ioctl-based rawiso interface, which is
-	more efficient.  You should really be using libraw1394 for raw1394
-	access anyway.
-Who:	Jody McIntyre <scjody@modernduck.com>
+When:	June 2007
+Why:	Deprecated in favour of the more efficient and robust rawiso interface.
+	Affected are applications which use the deprecated part of libraw1394
+	(raw1394_iso_write, raw1394_start_iso_write, raw1394_start_iso_rcv,
+	raw1394_stop_iso_rcv) or bypass	libraw1394.
+Who:	Dan Dennedy <dan@dennedy.org>, Stefan Richter <stefanr@s5r6.in-berlin.de>
+
+---------------------------
+
+What:	dv1394 driver (CONFIG_IEEE1394_DV1394)
+When:	June 2007
+Why:	Replaced by raw1394 + userspace libraries, notably libiec61883.  This
+	shift of application support has been indicated on www.linux1394.org
+	and developers' mailinglists for quite some time.  Major applications
+	have been converted, with the exception of ffmpeg and hence xine.
+	Piped output of dvgrab2 is a partial equivalent to dv1394.
+Who:	Dan Dennedy <dan@dennedy.org>, Stefan Richter <stefanr@s5r6.in-berlin.de>
+
+---------------------------
+
+What:	ieee1394 core's unused exports (CONFIG_IEEE1394_EXPORT_FULL_API)
+When:	January 2007
+Why:	There are no projects known to use these exported symbols, except
+	dfg1394 (uses one symbol whose functionality is core-internal now).
+Who:	Stefan Richter <stefanr@s5r6.in-berlin.de>
+
+---------------------------
+
+What:	ieee1394's *_oui sysfs attributes (CONFIG_IEEE1394_OUI_DB)
+When:	January 2007
+Files:	drivers/ieee1394/: oui.db, oui2c.sh
+Why:	big size, little value
