#6911Prevent action on disabled elements, both triggering and bound via .live()
#7531 Fix again for IE9RC. Enhances ajaxSetup so that it can take an optional target option, in which case target will be updated instead of ajaxSettings. That way, fields that shouldn’t be deep extended can be listed and dealt with in one place. jQuery.ajax now makes use of ajaxSetup with target to create its internal settings object
#7568 Follow-up fix for #5862. Objects with a length property weren’t serialized properly by jQuery.param
#7653 Changes regexp to detect local protocol so that it will accept any protocol finishing by -extension
#7668 Sizzle and jQuery QUnit tests are out of sync
#7912 This change makes .cur() more .cssHooks friendly. .cur() now returns the unmodified value by .css() if it isn’t a number, number-alike or a value that needs a fallback to 0.
#7922 Fixed an issue where live(‘click’) doesn’t fire when live(‘submit’) is bound first in IE
#7945 Make jQuery.param() serialize plain objects with a property named jquery correctly
#8033 jQuery 1.4.4+ fails to load on pages with old Prototype (<= 1.5) or Current Prototype + Scriptaculous in IE
#8039 Selectors with HTML5 input types not work in IE6/7
#8052 Update jQuery.support.noCloneEvent test to function properly in IE9
#8095 Properly handles the case where browser cache needs to be bypassed while server-side logic still delivers proper 304 responses. Unit test added
#8098 Use the fast document.head when available
#8099 Always restore to correct display value based on element’s expected default display
#8107 Fix argument handling for $.ajax for multiple method signatues and add test case
#8108Temporary fix for jQuery metadata being exposed on plain JS objects when serializing with JSON.stringify to avoid compatibility-breaking changes. A proper fix for this will be landed in 1.6
#8115 Renames all references to jXHR with jqXHR in the code (like was done in the doc)
#8123 The default for .clone() is to not clone any events
#8125 Status is set to 200 for requests with status 0 when location.protocol if “file:”. Added test/localfile.html to control it works
#8129 Fix cloning multiple selected options in IE8
#8135 Makes sure any exception thrown by Firefox when trying to access an XMLHttpRequest property when a network error occured is caught and notified as an error. Added test/networkerror.html to test the behavior
#8138 Access to document.location is made only once at load time and if it fails (throwing an exception in IE when document.domain is already set), we use the href of an A element instead
#8145 Added readyWait tests
#8146 introducing the xhrFields option with is a map of fieldName/fieldValue to set on the native xhr. Can be used to set withCredentials to true for cross-domain requests if needed
#8152 applying the same special cases for protocol “chrome-extension:” as were for “file:” (needs tests). Re-organizes and fixes the handling of special cases for HTTP status code in the xhr transport
