The browser is available in 95 languages, and also contains updates to support more modern web standards, such as more support for the new CSS3 standards being created. CSS text shadow, CSS 3D transforms, CSS3 transitions and animations, CSS3 Gradients, and SVG filter effects will all be in this release of the browser that people have been known to "love to hate".
For those concerned about privacy, IE10 features a "Do Not Track" feature that is turned on by default. Do Not Track is a feature that makes it harder for web advertisers (especially) to track you, by not allowing certain cookies and sending a Do Not Track statement in every HTTP header.
Here's a full bulleted list of improvements, straight from MSDN. I took one bullet and added it at the top for emphasis, as I myself personally have been trying to get my rotating banner to work under IE, and with this release I hope it starts working:
- Create rich visual effects with CSS Text Shadow, CSS 3D Transforms, CSS3 Transitions and Animations, CSS3 Gradient, and SVG Filter Effects
- More sophisticated and responsive page layouts with CSS3 for publication quality page layouts and responsive application UI (CSS3 grid, flexbox, multi-column, positioned floats, regions, and hyphenation), HTML5 Forms, input controls, and validation
- Enhanced Web programming model for better offline applications through local storage with IndexedDB and the HTML5 Application Cache; Web Sockets, HTML5 History, Async scripts, HTML5 File APIs, HTML5 Drag-drop, HTML5 Sandboxing, Web workers, ES5 Strict mode support.
- Beautiful and interactive Web applications with support for several new technologies like CSS3 Positioned Floats, HTML5 Drag-drop, File Reader API, Media Query Listeners, Pointer Events, and HTML5 Forms.
- Improved Web application security with the same markup and support for HTML5 Sandbox for iframe isolation.
