+.ALTER
+	Swap left and right header on even numbered pages.
+
+.GENSET
+	GENSET n now sets the counter to n-1, so that the next GENNUM produces n.
+
+(control-g)
+	now can take one argument, which is the counter number to increment.
+.LS
+
+	no longer exists.  Use blank lines instead of .SP if you want the old
+	LS SP effect.
+
+/T, typein from tty
+	In order to get typein from the TTY, you must now use the /T switch
+	instead of terminating the command line with a LF.  TJ6 will accept
+	command or text input from the tty, with reasonable rubouts, untill
+	tty input is terminated with a .APPEND, .INSRT, or the new command:
+
+.ET
+	which is now used to terminate input from the tty, instead of the
+	old CR, space.
+
+.XGP
+	now has the same effect as the /X switch, i.e., the default second
+	filename is XGP, not MEMO.
