The versioning switch is not a browser detect. PPK: “In other words, the versioning switch does not have any of the negative effects of a browser detect.”

Beyond DOCTYPE: Web Standards, Forward Compatibility, and IE8. This has huge implications for client-side web developers: IE 8 will include the ability to mark a page as “tested and compatible with the IE7 rendering engine” using an X-UA-Compatible HTTP header or http-equiv meta element. It’s already attracting a heated debate in the attached discussion.

CSS3 and the death of Handheld Stylesheets. I hadn’t looked at CSS 3 media queries before (which let you apply different styles based on media features such as screen width, height and colour availability)—they seem like a much smarter solution that handheld stylesheets and also appear to be preferred by device vendors.

CSS Transforms. WebKit can now do transforms (scale, rotate, translate and skew) in CSS via a new -webkit-transform property. Transforms behave like position relative in that they don’t affect the layout of the page. You can also provide a full affine transform matrix as a shortcut.

Tabula Fracta. Mozilla hacker Robert O’Callahan offers advice for anyone aiming to create a new rendering engine from scratch. The WHATWG’s work on specifying real-world browser behaviour and error models gets a well deserved mention.

Seeking market share, Microsoft removes WGA anti-piracy check from IE7. Hopefully this will accelerate the rise of IE7 over IE6.

Multi-Safari. Lets you run multiple versions of Safari on the same Mac. As with the multi-IE hacks, all versions use the same underlying HTTP libraries (which belong to the OS) so the simulation isn’t entirely accurate.

WebRunner 0.7—New and Improved. A simple application for running a site-specific browser for a service (e.g. Twitter, Gmail etc). This is a great idea: it isolates your other browser windows from crashes and also isolates your cookies, helping guard against CSRF attacks.

Opera 9.5 alpha, Kestrel, released. “With history search, Opera creates a full-text index of each and every page you visit, and when you go to the address bar, you can simply start entering words you know have been on pages you’ve visited before, and items matching your search show up.” I just tried this; it’s magic. I’m switching back to Opera from Camino.

Opera 9.5 (Kestrel). The latest Opera alpha includes a bunch of CSS3 features (including an almost full implementation of CSS3 Selectors) as well as the ability to use SVG for scalable background images.

Camino 1.1 Beta. Camino now has session saving. I simply won’t use a browser that doesn’t have this feature.
