I need to figure out differences.
%5B%5 is [], so it comes from some where in js, and it looks like array related.

ajax with

   data : {'move' : m, gnubgid : alt},

generates "move%5B%5=" so, I changed it to

   data : {'move' : m[0], gnubgid : alt},

and it gives the right result.

m comes from

 var m = mv.match(moveRegexp);

so I guess that 1.4.0 has changed over match object handling on serialization.


Param serialization now happens in the PHP/Rails style by default. You can use jQuery.ajaxSettings.traditional = true; to use traditional parameter serialization.

PHP/Rails means "recursive". If match object is an iterable of strings, then it is reasonable.
