The first Safari update is available from you “Software Update”, it’s version 3.0.2: recommended to all of Safari users.
Apple.com website has also been updated featuring an iPhone guided tour, which is mainly intended to prepare the “field” for iPhone’s launch (june 29th for the USA).
I also noticed that Apple.fr still hasn’t been restyled.

You can watch the video at Apple.com or just download the full “Guided Tour” video (175 mb).
Apple also pushes forward iPhone’s internet capabilties with a YouTube player an there’s a noticeable new icon in one of the iPhone’s in Apple’s website.
If you have this message (An error occurred while attempting to join the chat) don’t panic, it’s nothing but an incompatibility with Safari 3 beta.
Two ways to fix this bug:
Solution N°1- uninstall Safari beta
OR
Solution N°2- download Chax 1.4.9 beta 1; as a reminder, Chax is a plug in for iChat that adds several “missing features” to OS X’s default chat client.
A trick I found in Mac OS X hints, and the web inspector is superb (iPhoto style):

It’s a single line to copy (type) in the terminal after quitting Safari:
defaults write com.apple.Safari WebKitDeveloperExtras -bool true
Restart Safari and you’ll find a new item “Inspect Element” in the contextual menu (that appears when you control + click somewhere on a page).
Apple.com has been redesigned and I’m speecheless, the new look is superb!The new design is the “new brushed metal” (introduced with iTunes 7), the search function is now on the menu bar; no more “Mac OS X”, it has been replaced by “Mac in which you can browse Apple.Com by Mac, applications etc…

Apple also released Safari 3 beta for PC and Mac!

Apple claims now that Safari is the fastest browser on ANY plateform!
You may know that when you drag & drop a picture or song on the Mail’s icon on the dock it will easilly create a new email containing the file you moved:once you tried this,sending e-mails will be faster and really enjoyable!
I recently noticed that this feature,which is simple but powerful, also interests texts!
1)When you’re on a webpage and some text seemed interesting to you,drag and drop it on the Textedit icon on the Dock:that replaces the copy&past command.
2)The feature i think will really be intresting:try to drag & drop a word (or a sentence) on the Safari icon on the Dock,just like this:

Guess what?Safari displays a window with a google research on the word you moved (wikipedia in our case)!

I think this is a nice way to make very fast researches on the net.
Here’s a quick trick on how to add super fast links to your del.icio.us via Safari.
Just drag and drop these links to your Safari toolbar:
* post to del.icio.us
* my del.icio.us
Here’s the final result:

When you’re on a website you’d like to add to del.icio.us just click on the “post to del.icio.us” button on your toolbar and it will be added. To see your del.icio.us pages, click on the “my del.icio.us” button.
MacWorld UK has reported that a fully up-to-date system running Safari 2.0.3 (417.8) and Mac OS X 10.4.5 is vulnerable to a recently discovered security flaw. It can be exploited by malicious people to compromise a user’s system. The source of this flaw is the way Mac OS X Tiger processes the meta data of the file associations of Zip archives. To make things worse this exploit allows Safari to automatically execute malicious code when visiting a website.One known way to avoid this vulberability is to disable the “Open safe files after downloading” option in Safari. If you want to test if your Mac is vulnerable Secunia is kind enough to provide a working demonstration.
