+2009.11.21 - GNU nano 2.1.99pre2 is available for a special pre-Black
+		Friday discount.  Included are some (hopefully
+		final) fixes for issues with last page display
+		caused by the soft wrapping code, and a fix for
+		a long standing issue with hittig the home key when 
+		going through the search history.  On the features
+		front, nano will now attempt to retain the proper 
+		ownership and permissions when trying to create a 
+		.save file due to receiving a signal.  Nano can also 
+		now unbind keys from one or more menus via the 'unbind' 
+		keyword.   Finally, passing --fill or --nowrap on 
+		the command line will now override any related 
+		.nanorc entries.  Speak now or forever hold your bugs!	
+
+2009.11.15 - GNU nano 2.1.99pre1 "take a bow" is out there, man, it's
+		out there all right.  This release contains mainly 
+		bugfixes, underscoring that we are preparing for the 
+		next stable series release.  Included are many fixes 
+		for the new soft wrapping code, compiler warning tweaks, 
+		and the modification time warning no longer triggers 
+		when saving a file as a new name.  Also include are 
+		some fixes for various nanorc options, and there are 
+		surely more bugs to find before we call the code base 
+		stable, so please keep those reports coming!
+
+2009.09.14 - GNU nano 2.1.11 is on very thin ice, very thin ice, very thin
+		ice.  This release includes two new features: first, nano
+		will check whether the current file is writable when it
+		is opened, and warn if it is not on the status bar. Secondly,
+		a new soft-wrapping (AKA full line display) option is 
+		available, which will attempt to fully display the contents
+		of lines longer than the width of the screen without the
+		usual truncation and a '$' symbol at the end of the line.
+		It can be enabled via Meta-$ inside the editor, via the 
+		-$ or --softwrap command line flags, or "set softwrap" 
+		in your .nanorc).  As always please report any bugs to the 
+		nano Savannah project page
+		(http://savannah.gnu.org/bugs/?func=additem&group=nano)
+		Remember: data loss happens, back up your files.
+
 2009.07.28 - GNU nano 2.1.10 "Ellie" is released.  This version includes
 		various fixes for portability including some older HP-UX
 		compiler combos, various compiler warnings, and some crash
