For what it's worth this is my solution to the upcoming 0.5 release. It's
certainly not elegant, but it works, and it means I don't have the hassle of
managing two versions of the commands whilst people migrate.
var isParser2 = function(){
var prefs = Components.classes["@mozilla.org/preferences-service;1
"].getService(Components.interfaces.nsIPrefService);
var branch = prefs.getBranch("extensions.ubiquity.");
return (branch.getPrefType("parserVersion") != 0) ?
branch.getIntPref("parserVersion") == 2 : false;
}
if (isParser2()) {
/* Parser 2 version of the CmdUtils.CreateCommand calls here */
/* ... */
} else {
/* Parser 1 version of the CmdUtils.CreateCommand calls here */
/* ... */
}
(Full code is here:

)
Hope it helps.
