Apple released the final version of the browser Safari 4. The program is available for Mac OS and Windows users. Among the main changes noted feature "Top Sites", the transition to new engine processing the Nitro JavaScript, search your browsing history and mode Cover Flow.
Compared with the latest beta version of the changes are not so much, the most important thing - this is a departure from the placement of the tabs above the address bar. Similarly, the tabs were placed in the third version of Safari, so if you are not fond of beta testing, the difference may not be noticed.
We go through the changes that distinguish the "four" from the previous version.
In Safari 4 now has a "Top Sites", which reminds operovsky Speed Dial. Thanks to her, in a new tab displays thumbnails of the most visited Internet resources.
Cover Flow, previously available in iTunes, and got to the browser. You can view thumbnails of previously visited sites. This feature can be especially useful if you are looking for a gallery or photosite. In other cases it is better to use full-text search in history, who also appeared in Safari 4.
In addition, it is worth noting the new engine the Nitro, which is responsible for handling JavaScript. It is faster than IE 8 by 8 times (ironically) and 4 times faster than Firefox 3. In practice, this means that such web-based applications like GMail and Google Reader will run faster.
In Snow Leopard, which will hit the stores in September, Safari 4 will run as a 64-bit application, which will further increase the speed of processing JavaScript. Plugins will run in separate processes, a failure of one of them will lead to crash the whole application.
