Add space before curly brace to make jQuery-tmpl happy.
Find moved items when using observableArray#splice with arrayChange notifications.
Use jQuery if it's loaded once ko.applyBindings is called. Update checks for jQuery to use truthiness instead of "typeof".
Fix minor error in build script.

jQuery in sources
In IE<=8, delay deletion of options until after new items are added to fix a selection bug.
Make jQuery.cleanData optional by adding an extensibility point for cleaning external data that can be overridden.

KO 3.0.0 error with jquery templates containing any 'value' bindings
Instead of using special workaround code to handle click weirdness in IE<9 and jQuery, use the element.click method. This is the same fix that jQuery added in 1.9 for checkboxes (but not for radio buttons).
Fixes the problem that IE<=8 throws "Unspecified error" when text or options binding is used in a pop-up window.

KO 3.0.0 bug in IE8 - options/optionsCaption
Specs for "fn" in general
Ensure spec count remains consistent across browsers

Otherwise it’s hard to tell if some syntax error has caused a bunch of
specs not to run on a particular browser
Added equivalent proto assignment spec for ko.subscribable
Instead of overwriting ko.*.fn.__proto__ every time an observable/subscribable/observableArray is constructed, define the inheritance chain in a one-time setup action
Make sure observables can use Function.prototype methods when overwriting __proto__
Make the various array methods (forEach/map/filter) provide the array index to their respective callbacks
