What is a Platform Preview?
These are releases we send out on a regular basis. We are currently aiming to release a platform preview every 8-12 weeks, this one was released 11 weeks after IE10 PP1. These previews contain implementations of features that are close to final and are less likely to change, but by no means are guaranteed to represent the final implementation that we put in our shipping browser.
As well as platform previews we also release features on HTML5 Labs. HTML5labs.com is our way of bringing you interesting implementations so that you can test and provide feedback on them, with the caveat that the implementation will change and when we change there will likely be breaking changes. The File API has been the first feature from HTML5labs.com that has graduated to the Platform Preview. This graduation is an acknowledgement that were are happy that the standard is stable.
With every new Platform Preview we also release new demos to showcase what can be achieved with the new features, Platform Preview 2 is no exception here are the new demos:
- Fireflies highlights HTML5 canvas, audio, video and CSS gradients – View Site
- How Stuff Works illustrates how different browsers today give different results. The quality and correctness of different browsers’ HTML5 engines vary widely this is something that all browser vendors must work on to improve adoption. At Microsoft we have submitted thousands of test to the W3C so that other browsers can benefit from the investment we have made in testing our browser to ensure it complies with the HTML5 standard.
