Apple is preparing to release Safari 1.0 - the first full version of its Mac OS X browser.

The company told MacCentral that the Safari beta test has been "a great success", and that it will be released "soon".

Apple also revealed that Microsoft's Mac Business Unit will put development resources into revenue-earning products for the Mac, including Office, Entourage, the Entourage Exchange Client and Virtual PC.

The revelation follows recent news that Microsoft is to cease development of Internet Explorer for Mac, a decision Microsoft said it took because of the success of Safari.

In related news, Microsoft has released Internet Explorer 5.2.3 - expected to be one of the last updates for the product. It offers better security and performance, and enhances browser compatibility for users who work on a network with secure authentication or with proxy servers.
