This post announces an update to Graded Browser Support. The GBS page on the YUI site always has the most current information. This post includes a list of primary changes, the updated chart of browsers that receive A-grade support, the GBS forecast, and notes specific to the YUI Library.
These changes are included in this update.
- A-grade support for Firefox 3 begins.
- A-grade support for Firefox 2 is reduced to Win XP and Mac 10.5.
- A-grade support for Opera 9.5 begins on Win XP and Mac 10.5.
- A-grade support for Win 98 is discontinued, as previously forecast.
|Win 2000||Win XP||Win Vista||Mac 10.4||Mac 10.5|
The dagger symbol (as in ‘Firefox 3.’) indicates that the most-current non-beta version at that branch level receives support. Put another way, means ‘the most recent’ instead of ‘all.’
In addition to the effective-immediately changes, we’re keeping our eyes on pending developments.
Internet Explorer 8
GBS does not extend A-grade support to beta versions of browsers. (They receive X-grade support by definition.) However, it’s important to be aware of forthcoming releases, especially from established brands that enjoy rapid adoption once generally available (GA). We are currently watching the development progress of Internet Explorer 8.
We made an exception to our ‘no-betas’ stance during IE7’s beta phase in recognition of IE’s market share and ability to promote rapid adoption. The exception — committing development and QA resources to provide A-Grade prior to a GA release — gives us an opportunity to learn the new browser’s quirks and provide feedback while it is still being developed. And it means our sites are prepared when it goes GA. We will likely extend the same accommodation to IE8. Stay tuned.
Notes Specific to the YUI Library
YUI version 2.5.2
YUI 2.5.2, released May 28, 2008, includes full support for Firefox 3.0 and Opera 9.5, even though those two browsers were just added to GBS in this update.
