Opera announced yesterday the arrival of the first “point” update to its world renowned mobile browser, Opera Mobile 11. The latest version, Opera Mobile 11.1, is now available for download from the Android Market.

According to Opera, the update contains changes and new stuff that the development team gathered from user feedback. New features have been incorporated to “make browsing on an Android…easier than ever before.” The chief feature highlights of the update are support for Google AutoComplete, domain auto-suggest, and improvements to text selection.

Under the hood, Opera has upped Opera Mobile’s rendering engine to Opera Presto 2.8.149. The upgrade is supposed to improve page loading performance and better compliance with standards.
