New features

Opera Presto 2.6 rendering engine

Opera 10.60 final contains the Opera Presto 2.6 rendering engine, which improves stability and adds support for the following new Opera features.

Geolocation services

User-enabled geolocation services are provided through Google Location Services (GLS).

IP address and WiFi recognition are implemented.

IP address recognition works with GLS by recognizing your IP address and telling you the cordinates based on it.

WiFi recognition works with GLS by gathering and then sending a list of all nearby wireless networks including MAC (Media Access Control) address, SSID (Service set identifier) name, and signal strength, which returns your coordinates.

An address bar map pin icon indicates a Web page is accessing the Geolocation API.

Opera geolocation services support the W3C Geolocation API Specification (http://www.w3.org/TR/2008/WD-geolocation-API-20081222/).

A user decides to share or not share their device location with a Web site based on trust; see section 4.2 (http://dev.w3.org/geo/api/spec-source.html#privacy_for_recipients) of the W3C Geolocation specification.

Further information is available at the Opera Desktop Team blog: "The return of Geolocation" (http://my.opera.com/desktopteam/blog/2010/02/05/skin-fixes-unite-and-then-some).

See this Opera demo (http://html5demos.com/geo).

Offline Web Applications

Support is added for Offline Web Applications (http://dev.w3.org/html5/spec/offline.html#offline) implementing the user interface for caching.

This allows documents to communicate with each other regardless of their source domain, and is designed in a way which does not enable cross-site scripting attacks.

See this Opera demo (http://html5demos.com/offlineapp).

Web Workers

Web Workers (http://www.w3.org/TR/workers/) is an API for running scripts in the background independently of any user interface scripts. This allows for long-running scripts that are not interrupted by scripts that respond to clicks or other user interactions, and allows long tasks to be executed without yielding to keep the page responsive.

See this Opera demo (http://html5demos.com/worker).

WebM

The WebM format consists of the VP8 video and Vorbis audio codecs wrapped inside a .webm container. It is based on the Matroska media container format, and offers high-quality video with fast seeking.

WebM works together with the HTML5 <video> element supported in the Opera Presto rendering engine.

See these Opera articles:

Welcome, WebM <video>! (http://labs.opera.com/news/2010/05/19/)
