Opera 10 Alpha

opera10_2

Ya son las 10 de la mañana y estuve probando el nuevo Opera Alpha, y vaya que me gusto su nuevo “look”, por asi decirlo. Esta nueva versión cambia de núcle Presto 2.1 a la 2.2 y las características explícitas en la Web de Opera son:

Rendering

Significant performance improvements

Added Web font support, allowing the download of fonts specified in font descriptors in @font-face at-rules; TrueType (TTF), OpenType (OTF), and SVG fonts are supported (demos)

Achieved 100/100 and pixel-perfect rendering on the Acid3 test

Pretty-printing of unstyled XML (using unstyledxml.css in the Styles sub-directory of Opera’s installation directory)

Added support for CSS3 RGBA color values (demo)

Added support for CSS3 HSLA color values (demo)

Added support for the CSS3 color: transparent value

Improved HTML5 support, including end-tag and start-tag parsing, whitespace parsing, and DOCTYPE parsing

CSS files must be served with the correct MIME type (“text/css”) in Strict mode or they will be ignored

JavaScript/DOM

New regular expression engine, which greatly improves performance on regular-expression-heavy pages such as the SunSpider JavaScript Benchmark

Added support for the W3C Selectors API

Renamed the objects returned by getClientRects() and getBoundingClientRect() to ClientRectList and ClientRect instead of TextRectangle and TextRectangleList, respectively

XMLHttpRequests will now trigger start-loading/end-loading events

Removed the proprietary window.setDocument method

Added support for the SVGElement.currentFps and SVGElement.targetFps properties to read and control, respectively, SVG frames per second

The load event for scripts is now sent after the script is executed rather than before

The load event is now sent to frame/iframe/object elements before it is sent to the document

A highlight will no longer be added when HTMLElement.focus() is called unless keyboard navigation is already activated

Other

Removed UTF-32 encoding support

User JS files will now be executed in alphabetical order rather than file system order

HTML5 canvas elements can now export images to the JPEG format

HTML5 canvas transforms are applied when building a path, not when painting it (this change is made to work like Mozilla)

The first ID (instead of the last) is now used on pages with duplicate IDs when navigating to fragment IDs

Added support for the altGlyph element in SVGs

Added support for 32-bit alpha in BMP and RLE-encoded BMP images

Implemented HTML5′s algorithms for detecting charsets in HTML

The http://www.w3.org/TR/REC-html40 namespace is no longer treated as an alias to http://www.w3.org/1999/xhtml
