Google announced its first update for Chrome on iPhone and iPad in version 21 / 21.0.1180.77.

The update adds the power to share directly from Chrome to social networks and email. Other features include: “more actionable” sync register error messages, improved detection for the welcome tour, and fixes for pages loading blank in Incognito mode.

Not a giant update, but an update nonetheless, for the highly anticipated mobile version of the well-liked browser. Google launched the iOS version of Chrome in June. Here’s a hands-on if you’ve yet to check the waters.

In other Google-related browser news, Google has extended its partnership with Opera to stay the default search provider.

Chrome’s operating system counterpart, Chrome OS, also got some tweaks this week. More on that here.
