+
+	* [shogi-server] Improve timed-up detection (continued).
+	  The server now checks timed up when it receives a-single-space keep
+	  alive messages as well.
+	  Thanks to mizar for reports and patches.
+	  (Closes #40821)
+	* [shogi-server] Support listening on IPv6 addresses
+	  Thanks to mizar for a patch.
+	  (Closes #40822)
+	* [shogi-server] Make invalid comments illegal
+	  Some client sent moves with comments in an invalid format like
+	  "+7776FU '* 30 -3334FU +2726FU". Such messages are now deemed
+	  illegal.
+	  Thanks to mizar for a report.
+	* [shogi-server] Bump up the revision to 20201206
