Shortly after an update to Chrome for Android last week, Google ended up recently updating Chrome for iOS for the first time since December. The Android version of the app included several features such as improved scrolling performance, increased responsiveness for pinch zooming on pages and faster interactive pages with the iOS app receiving an update with the ability to long-press on the back button to quickly access any page in the tab history.

The newest version of the free mobile browser allows iOS users to share a web page via Messages and also includes several stability enhancements as well as unspecified security improvements and bug fixes. Another notable feature that was included by Google includes the ability for iOS users to see their search term in the omnibox instead of the long search URL. According to Google:
This will help you refine search queries and view more content on the results page. This feature will roll out in the coming weeks, so you may not see it right away after upgrading.
