+* Fixed that *rest parameter in map.connect couldn't accept an empty list #1037 [Dee.Zsombor@gmail.com]
+
 * Added :confirm option to link_to_remote just like link_to has #1082 [yrashk@fp.org.ua]
 
 * Added minute_step as an option to select_minute (and the helpers that use it) to jump in larger increments than just 1 minute. At 15, it would return 0, 15, 30, 45 options #1085 [ordwaye@evergreen.edu]
