Our latest update to the official Wikipedia Android app is now available on the Google Play Store! [1]  Here's a high-level overview of the features introduced in this release:

* Lead images -- When navigating to an article, the app now displays the most relevant image from the article at the very top, with the image expanded to fit the width of your screen, and the title of the article overlaid onto it.

* Image gallery -- Tap on any image in an article (including the lead image) to see a full-screen gallery where the image may be panned and zoomed. You may also "swipe" left and right to browse through other images that are part of the article.  There are also options, accessible from the toolbar on the top right, for sharing the image to your favorite social media apps, saving it directly to your device, showing miscellaneous information (Exif) about the image, and navigating to its File: page on Wikipedia.

* Descriptions from Wikidata -- The app is now integrated with Wikidata [2] to provide quick descriptions next to search results, as well as in Nearby results, in disambiguation links, and in further reading suggestions.

* Search enhancements -- We have improved the search experience (accessible from the top toolbar) to intelligently incorporate search results from title-only searches, as well as full-text searches, so that typing a search term will give you the most relevant result.

* Disambiguation and "page issues" links have been improved and restyled.
* Suggestions for further reading are provided at the bottom of articles.
* Infoboxes and other tables contained in articles are now collapsed by default.
* The toolbar at the top has been restyled to follow the new Material Design guidelines introduced in Android 5.0.
* When editing, templates are shown in a different color to help differentiate between the template and regular text.

Enjoy!
