+2010.01.17 - GNU nano 2.2.2 is released for you, you, you.  This
+		release includes fixes for: crashed when writing
+		backup files in certain conditions, improper
+		screen centering when moving up/down in various
+		combination of smooth scrolling and soft wrapping modes,
+		a search crash on the armel arch, and issues with
+		lots of keybinding customizations causing crashing
+		particularly on FreeBSD.  Also included are better
+		help menu entries for forward/back in the file browser,
+		some man page tweaks and one assert fix.   As always,
+		share and enjoy!
+
+2009.12.12 - GNU nano 2.2.1 "DLR strikes back" is open for business.
+		This release fixes many bugs, including: missing
+		keybindings for page up/down and GotoDir in the browser, 
+		^P/^N in the help menu, and restoration of M-W as the 
+		default re-search binding.  Other fixes include several
+		issues with compiler warnings and configure options, and 
+		documentation updates, including the nano texinfo manual, 
+		nano and nanorc man pages, and UPGRADE file, and some
+		missing syntax highliting entries for the saple nanorc.
+		And no release would be complete without the latest round
+		of 'final' soft wrapping fixes!  Finally, nano will no 
+		longer print a warning when attempting to insert the 
+		contents of a read-only file into an existing buffer.  
+		Enjoy and Happy Hanukkah.
+		
+
+2009.11.30 - GNU nano 2.2.0 "Doc Brown" is released!  The culmination
+		of almost two years of development and hot on the heels
+		of nano's 10th birthday is available for all your
+		editing needs!  Bugs fixed since the last release
+		include several fixes for tiny mode (involving both
+		the help keys and replace menu text), more 'final'
+		fixes for soft wrapping, and several typo and documentation
+		updates including nanorc tweaks and a new syntax 
+		highlighting file for makefiles. Also included is a long
+		standing fix for random crashing when using nanorc on
+		FreeBSD, and nano will no longer clear the screen on
+		suspend to maintain compatibility with other *nix editors.
+		For those who haven't been playing along at home, please
+		see the official web page for the summary of new
+		features since 2.0.  Special thanks to all who have 
+		submitted bug reports recently in support of our new 
+		stable release, and apologies for all those bugs we 
+		didn't yet find :-) Peace to all.
+
+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
