 *SVN*
 
+* Added to_s(:db) to Range, so you can get "BETWEEN '2005-12-10' AND '2005-12-12'" from Date.new(2005, 12, 10)..Date.new(2005, 12, 12) (and likewise with Times)
+
 * Moved require_library_or_gem into Kernel. #1992 [Michael Schuerig <michael@schuerig.de>]
 
 * Add :rfc822 as an option for Time#to_s (to get rfc822-formatted times)
