## Improvements:

* Upgraded AngularJS framework to 1.8.2

  * Version 1.8.2 meteoric-mining corrects `$sceDelegate` to ensure that `resourceUrlWhitelist()` is identical to `trustedResourceUrlList()`.
* Upgraded JQuery to version 3.60.

  * Version 3.60 corrects security issues during a pen test.

## Bug Fixes

* Fixed a bug where the selection of a query:suggestion component added the following to the URL: an `mq` parameter and an `mq value` surrounded by quotes.
* Fixed a bug where the facet filter for a facet already applied did not clear when `select=toggle`.
* Fixed a bug in the search:box with the action attribute where the queries on the search submission page were re-triggered *before* the page was redirected to the value listed in the action attribute.
* Fixed an issue where extra requests were made when a new query was submitted *if* a fixed header and infinite scroll were used.
* Fixed an issue to ensure a facet filter that contains special characters cannot be deselected.
