Chrome 25 comes with a feature that allows you to see list of previous pages if you tap and hold the Back button in Chrome, just like in the desktop version. The other feature offers you the possibility to share links via Messages.
Google promised to change the way Google searching works in the iOS Chrome version “over the coming days” and notes that “The company has started experimenting with adding a search box to the browser’s new tab page as well as keeping queries in the omnibox after a search is performed.”
In a nutshell, the new tweaks of the search engine in Chrome for iOS will allow you to see the search term in the Omnibox directly and to easily refine your search queries plus additional results on the search page.
There were also improvements added to the stability and security of the browser, also bug fixes. The latest version of Chrome is available on Apple App Store.
