Backbone, from 1.1.2 to 1.2.3. Underscore, from 1.6.0 to 1.8.3.
The new versions of Backbone and Underscore offer numerous small bug fixes and some optimizations and other improvements. Check the [http://backbonejs.org/#changelog Backbone changelog] and [http://underscorejs.org/#changelog Underscore changelog] for the full details.
The new versions include some significant changes that may break existing code. Plugins or themes that rely on the bundled Backbone and/or Underscore libraries should carefully check functionality with the latest versions and run any available unit tests to ensure compatibility.
Some changes of note that were addressed in core as part of this upgrade:
* `_.flatten` no longer works with objects since Underscore.js 1.7. `_.flatten()` working with objects was an unintended side-affect of the implementation, see [https://github.com/jashkenas/underscore/issues/1904#issuecomment-60241576 underscore#1904]. Check any `_flatten` usage and only flatten arrays.
* As of Backbone 1.2.0, you can no longer modify the `events` hash or your view's `el` property in `initialize`, so don't try to modify them there.
* Since Underscore 1.7, Underscore templates no longer accept an initial data object. `_.template` always returns a function now so make sure you use it that way.

When the same nav menu is shown multiple times on a page, only the first instance of the nav menu will include `id` attributes. Subsequent instances will have the `id` attributes omitted. However, in both cases the underlying nav menu item's post ID is available among the `class` names, so the post ID can be more reliably obtained from `class` instead of the `id` attribute.

- Fix not displaying anything when the URL is only a fragment. Show the whole URL.
- Fix editing a link when it is the very first word in the editor.
- Fix editing a link then some of the surrounding text or space is selected. Change the selection to only the link node.
- Add placeholder when adding new link.

* Introduce `WP_Customize_Manager::get_nonces()` to consolidate logic for retrieving nonces.
* Export nonces centrally in `wp.customize.settings.nonce` with each request and update nav menus preview to utilize.
* Send updated nonces to preview upon `nonce-refresh`.
* Request full preview refresh if Nav Menu selective refresh request fails (e.g. due to bad nonce).
* Update nav menus and widgets in Customizer to utilize `customize_refresh_nonces` for exporting nonces and keeping them up to date.

* Ensure that Setting `Value` objects in preview get initial `_dirty` flag set if values among POST data.
* Upon `saved` event, send `saved` message to preview with the `response` to trigger `saved` event there.
* Reset `_dirty` flag for all setting `Value` objects in preview upon `saved`.
* Continue to create settings synced from pane even after initial bootstrap, and create them as dirty.
* Ensure that `id` property is set for setting `Value` objects in preview.

Add missing `params.completeCallback` to `MenuItemControl.focus()` for parity with `Control.focus()`. Also adds `params` to `MenuItemControl.expandForm`, `MenuItemControl.collapseForm()`, and `MenuItemControl.toggleForm()`.

* Prevent following jump links (starting with `#`), but instead scroll that element into view.
* Prevent following links clicked in the Customizer if shift key is pressed when clicking; this fixes an issue when trying to shift-click on a widget or nav menu item (#32681) to just focus on the control in the Customizer.

Subviews are stored internally on the Subview manager as an object. The object
is composed of key-value pairs where the key is a jQuery selector for a view,
and the value is an array of views that matching the selector.
To extract subviews, `_.flatten()` was used to collate the nested arrays of
views into a single view. However, `_.flatten()` is not intended to be used
for objects, and this unintended functionality breaks in newer versions of
Underscore.js.
Instead, we'll use `_.values()` to extract the arrays of views first,
and then flatten the array of arrays.

In the data sent to us from the embedded iframe by postMessage(), the secret value is being used directly in a document.querySelectorAll() call without first being validated or escaped.
In theory, this could lead to some broken embeds.

Older versions of WordPress will convert those `&` characters to `&`, which makes for some non-functional JS. If folks are running an older release, let's not make their lives more difficult than it already is.

Twemoji will replace the `img` with the emoji character, in the event that the image fails to load. We deliberately avoid trying to change that emoji character when it's changed back. We do need to replace emoji characters that are changed by something other than Twemoji, which this rectifies.
