+A NOTE ON THE CHANGELOG:
+Starting in early 2011, Tk source code has been under the management of
+fossil, hosted at http://core.tcl.tk/tk/ .  Fossil presents a "Timeline"
+view of changes made that is superior in every way to a hand edited log file.
+Because of this, many Tcl developers are now out of the habit of maintaining
+this log file.  You may still find useful things in it, but the Timeline is
+a better first place to look now.
