I've been playing with this browser since their last update.
Not bad. VERY fast. In fact, FASTER than Opera, which I thought was impossible!
Only real thing it's missing really, is an adblocker. Just got this update before coming here.
Good thing for the update too:
http://secunia.com/advisories/29846/Some vulnerabilities have been reported in Safari, which can be exploited by malicious people to conduct cross-site scripting attacks or potentially to compromise a user's system.
1) An error exists in the handling of URLs containing a colon character in the host name. This can be exploited to conduct cross-site scripting attacks when a specially crafted URL is opened.
2) An integer overflow error exists in WebKit's regular expression compiler in JavaScriptCore/pcre/pcre_compile.cpp. This can be exploited to cause a heap-based buffer overflow via specially crafted regular expressions with large, nested repetition counts.
Successful exploitation may allow execution of arbitrary code e.g. when a user visits a malicious web page.
The vulnerabilities are reported in versions prior to 3.1.1.
