Antwerp, Belgium - 11 July, 2008. 
Hyperion Entertainment is very pleased to announce that Amiga OS 4.1 has gone into final testing and is scheduled for release mid-Q3/2008. Building on the solid foundations of Amiga OS 4.0, Amiga OS 4.1 introduces a wealth of substantial new functionality which is a prerequisite for the deployment of industry standard applications on the Amiga platform.
State-of-the-art applications such as modern web-browsers, productivity software or digital imaging software typically operate on large datasets with a corresponding memory footprint which rapidly outstrips the physical memory of any computer system. Amiga OS 4.1 offers intelligent memory paging and uses transparent disk based memory - but only when you need it.
