Google has updated the iOS version of Chrome
to v25.0.1364.86. The primary change is that the browser now provides quicker access to a tab's history by holding down the Back button. For sharing webpages, though, links can now be sent through iOS' built-in Messages service.
Google also promising a pair of changes to the way search works "over the coming days." These include displaying search terms in Chrome's omnibox, instead of search query URLs, and the ability to refine search queries and see more results on the results page. Chrome is a free download and runs on any device with iOS 5 or later.
