**Release date:** 7 November 2018

## New features

* New tags:

  * [`advanced:text`](/docs/4/app-studio/reference/tags/lightning.directive.advancedText) creates an advanced search input field.
  * [`collaborate:comment-form`](/docs/4/app-studio/reference/tags/lightning.directive.collaborateCommentForm) renders a comment form.
  * [`collaborate:comment-list`](/docs/4/app-studio/reference/tags/lightning.directive.collaborateCommentList) displays a list of comments.
* New service: [`CollaborationService`](/docs/4/app-studio/reference/services/lightning.CollaborationService) accesses the Collaboration APIs.

## Improvements

* [`geo:map` tag](/docs/4/app-studio/reference/tags/lightning.directive.geoMap) improvements:

  * A new `drag` value for `events` changes the search range when the user drags the map; this works only with Google Maps.
  * The `draw` value for `events` now works with ESRI maps in addition to Google Maps.
  * The longitude filter is now created with the correct values.

* The [`search:facet` tag](/docs/4/app-studio/reference/tags/lightning.directive.searchFacet) can now be configured to display custom icons for expanded/collapsed facet lists using new `.collapsed` and `.facet-toggle` CSS classes. See the [CSS example](/docs/4/app-studio/reference/tags/lightning.directive.searchFacet).

* The [`instant:result-list` tag](/docs/4/app-studio/reference/tags/lightning.directive.instantResultList) has a new `children-selector` attribute for selecting the child elements that should be used for the arrow key selection mechanism.

## Other changes

* The [`media:image` tag](/docs/4/app-studio/reference/tags/lightning.directive.mediaImage) now respects the value of `image-service-url`, if defined.
