* Fix - Updated all Javascript functions so that the plugin is compatible with jQuery Version1.9 and backwards to version 1.6. WordPress still uses jQuery version 1.8.3. In themes that use Google js Library instead of the WordPress jQuery then there was trouble because Google uses the latest jQuery version 1.9. There are a number of functions in jQuery Version 1.9 that have been depreciated and hence this was causing errors with the jQuery function in the plugin.

= 2.1.2 - 2013/04/12 =
* Tweak - Added when install and activate plugin link redirects to License Key validation page instead of the wp-plugins dashboard.
* Fix - Link from search box drop down footer to All Results Search pages not working in Internet Explorer 8, 9 and 10.

= 2.1.1 - 2013/04/01 =

* Tweak -Jumped version from 2.0.1 to 2.1.0 with the release of the Predictive Search engine 100% accurate search results upgrade.
* Fix - Bug for users who have https: (SSL) on their sites wp-admin but have http on sites front end. This was causing search results to show a -1 in the drop down instead of the results because wp-admin with SSL applied only allows https:, but the url of admin-ajax.php is http: and it is denied hence returning the ajax -1 error. Fixed by writing a filter to recognize when https is configured on wp-admin and parsing correctly. If you do not have this configuration nothing changes for you, if you do have https on your wp-admin (or install it in the future) and http on the front end then Predictive Search now automatically detects that and works as it should.

= 2.0.1 - 2013/03/15 =
* Feature - All Results search page shortcode now shows as an image in the Search results page Visual text editor instead of the shortcode [woocommerce_search]. We have used an image to overcome some confusion about if the shortcode was a3rev Predictive Search or a WooCommerce shortcode function. Also has instructions (in English) about moving the shortcode to another page. After you upgrade, take a look.
* Fix - All Results search page breaking in some themes when the show Add to Cart button with search results feature is activated. Please update to this version now if you are experiencing this issue and this will fix it.
* Fix - Search function and shortcodes not working on themes that call the wpautop function before the shortcode function (very poor practice). The wpautop function auto adds the <p> tag to all white space in php functions and thus breaks our function. We use internal script rather than a js file for the serach function and shortcodes because a js file is always called on each page load even when it is not required. We have removed all white spaces and problem no longer exists.

= 2.0 - 2013/02/28 =
* Feature - Updated all plugin code to be WooCommerce V2.0 compatible with backward compatibility.

* Feature - Added a new styling lib for drop-downs and Options Ð this was important because it now uses the same lib as WooCommerce uses Ð makes excluding content a very easy thing to do for each content search taxonomy.
* Fix - Sort Search Results Pages show 'No Results' - The way the plugin was configured when a user hit 'Enter' while searching all of the Search Results pages where displayed for Sorting - Sort by Product Name | SKU | Product Categories | Product Tags | Posts | Pages - All of the Tabs showed even if a page had 'No Results'. This was done to save on database queries. We have written a special script and added it is fired when the user clicks 'Enter' while searching - it checks each page for results - if it finds 'No Results' it hides the Page tab and if it finds results if does nothing, when it is finished doing the 6 queries it goes back to sleep. The result is only 6 extra queries being done and super fast and only shows pages that have results.
* Fix - Undefined variable mediumSRC notice showing in search box dropdown when product does not have a featured image.We fixed by defining the variable.

* Fix - Version 1.1.4 fix where we removed Predictive Search filter 'posts_search' from single product page edit page to fix the Cross sells and Upsells search caused the SKU search filter to be corrupted because we use Wordpress ajax to show results in the widget drop down.
