Available on the Apple Developer Connection website:

Safari 4 Developer Preview for Leopard, Tiger and Windows.

To download it you need to register an ADC account (which is free).

This preview release is English only. To avoid Safari displaying a hybrid UI when installing on a Mac with languages other than English, deselect other languages in "Safari Info" window displayed after selecting Safari in the Finder and choosing File > Get Info. On Tiger, Safari 4 Developer Preview requires a previously installed version of Safari 3.1.1. Download and install Safari 3.1.1 from http://www.apple.com/safari/download/. Please include "Safari 4 Developer Preview" in any feedback.

Noticeable differences?

Is the new javascript engine included in this?

Noticeable differences?

UI-wise: none.

Performance-wise: JavaScript is massively faster. On my machine a run of the SunSpider benchmark takes 2416 ms, compared to roughly 3500 ms for Firefox 3 and Safari 3.1.1.

Is the new javascript engine included in this?

Yes. Hence the JavaScript performance boost.

FF3 b2

Safari 4

Latest WebKit (with Safari 4 installed)

WebKit r34388 = 3222.4ms

Firefox 3 = 3853.4ms

Safari = 4645.4ms

IE7 = 36858.2ms :laugh: Poor IE users

I think I might download this and test it out.

Javascript speed is very dependent on your setup. Try it out with Safari 4?

Might as well give it a whirl. I get 98/100 (Sometimes I got 97/100..) on the Acid3 page. So close. :p

Yes your right :) With Safari 4 i get 2034. But i love Firefox anyway :)

I don't get it... Firefox 3 here completes it in 2094.2ms.

[giga Veteran]

Different systems will get different speeds...:|

[Guest jgrodri]

is it stable enough to run it as my main browser?

Run it on your mac with Safari 4 and see what you get?

[ObiWanToby]

Will IE ever catch up, that is the question.

Sorry, I only noticed the posts about system speed after I made mine. On Safari 4 I get 1944.2ms:

PS. I wish Safari would default to Windows Standard font smoothing as the current Medium setting is horrible for a lot of sites. That's always the first thing I change but many users won't know to change it, making life harder as a web developer.

Firefox 3 RC2, Windows Vista x64.

Nice test, didn't known about it before (Y).

[Veedems Veteran]

It performs better slightly better (4700ms) than Firefox Minefield (5200ms) and Opera 9.5 (5700ms) on my box, but the fact that it sticks out so sorely in the Windows environment is a no go for me.

Nevermind, here are my results:

Sorry, Safari 4 is coming lol:

[Cormier6083]

Wow, here is Safari 4

Is it me or is Safari 4 really sluggish when browsing pages?

[giga Veteran]

Pretty Snappy? here, though I use WebKit.

Anyhow--neat little feature that I overlooked. Web Apps!
