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.
    - A user decides to share or not share their device location with a Web site based on trust; see section 4.2 of the W3C Geolocation specification.
    - Further information is available at the Opera Desktop Team blog: "The return of Geolocation".
* See this Opera demo.

Offline Web Applications
* Support is added for Offline Web Applications 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.

Web Workers
* Web 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.

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!
    - Opera supports the WebM video format
