We've argued that Microsoft needs to engage more with Web developers to give a better understanding of what the company is doing with its Web browser, allow them to provide feedback throughout the development process, and more broadly get them engaged with the development process. With Internet Explorer 9's Platform Preview, Microsoft has indeed taken steps to do exactly this. Though Microsoft still isn't releasing the nightly builds that other browsers offer, the Platform Preview definitely represents progress; it provides early access to IE9's core rendering and JavaScript engines, and will be updated approximately every eight weeks.The eight-week cycle was chosen because Redmond felt this provided the best trade-off between getting regular updates into developers' hands, ensuring that the preview releases are reasonably robust, and getting useful feedback that integrates well with Microsoft's own development processes. Each version will undergo reasonably extensive testing during the eight-week period, giving ample opportunity for bugs to be filed. For its part, the IE team has committed to investigating every single bug filed, and resolving all that it can.
Indications are that the Platform Preview has thus far been quite successful. Sources close to the matter state that some 700,000 copies of the preview have been downloaded, and that interest has been global in spite of the preview being a US English-only release. The top three bug report areas are SVG, compatibility, and then CSS, which certainly indicates that developers are taking an interest in testing the browser's new features and ensuring they work correctly. Of the hundreds of bugs filed thus far, the same source says that around 60 percent of them have been addressed by the development team.
These download numbers are substantial, and it could be make a good case in favor of this slower release strategy. The Mozilla group's weekly Status Meetings include information about the number of users of different prerelease versions of Firefox. During the lead-up to the release of Firefox 3.5, several hundred thousand people used the major betas, but the nightly releases were much less used, with perhaps 10,000-15,000 users. The Platform Preview is not anything near as usable as the Firefox betas, so 700,000 downloads is a strong showing.
Ars talked with IE General Manager Dean Hachamovitch briefly about the Preview. He said that IE9 testers seemed particularly interested in the browser's performance and graphical capabilities, as these areas of the IE 9 Test Drive site had received most traffic. This is also reflected in some third-party reactions. NVIDIA recently used the IE9 Platform Preview to promote the graphical capabilities of its new Ion2 platform—capabilities that IE9 can, of course, exploit due to its extensive hardware acceleration (the same hardware acceleration that leaves Windows XP users out in the cold).
Stability vs. automation
Microsoft's approach to browser development shows a strong commitment to the ideal of a stable, versioned platform, something that developers could reliably target for consistent results. This attitude is carried through to the Platform Preview. Unlike, say, Chrome's dev channel which automatically updates about once a week, ensuring that developers always have access to an up-to-date version, the IE9 Platform Preview will require manual updating. Though this has the obvious downside that developers might forget or not notice that a new version has been released, and hence may result in testing of obsolete versions, it maintains the important (to Microsoft) notion of predictability. With Chrome, a page might work one day and be broken the next by an automatic update, a behavior that can be confusing at best. Microsoft doesn't want IE developers to face a similar experience; instead, they will have to take deliberate action to update.
On the other hand, automatic updates are, in a sense, part-and-parcel of the Web experience. Websites can change their appearance overnight, and while this can be confusing to some, it's an unavoidable fact of Internet life. The case can certainly be made that browsers should follow websites' lead and update themselves; this gives users a browser that (by and large) keeps on getting better—faster, more capable, and with new features. Though occasional regressions will happen (wherein a new version breaks something that used to work) a robust development process should make these rare.
These advantages were acknowledged by Hachamovitch, especially for the more savvy, technically aware user (that is, users who are unlikely to be fazed by new features and improvements appearing within their browser automatically). But the company still prefers to take the more conservative approach to avoid problems of users being surprised by changes.
Hachamovitch was noncommittal about what the second Platform Preview release would contain when released next month. At MIX10 we saw demonstrations of HTML5 video in a build of IE9. The version released last month, however, didn't include video support. HTML5 video is surely one of the most eagerly anticipated IE9 features. It will ship in a Preview release eventually, but we do not know when.
The Platform Preview program is still in its early stages, and this is the first time that Microsoft has developed its browser in this way; there may yet be refinements to the program as both the company and third parties learn the best way to work together, and there's no news yet of what will happen once IE9 moves into beta.
Thus far, at least, it looks like the scheme has been successful at getting third-party developers involved with IE9's development, which has to be good news for both sides.
