History of AmigaOS

AmigaOS 4.0's inception dates back to 2002 when an agreement was reached to port AmigaOS to the PowerPC platform.

Building on the sources of AmigaOS 3.x, Hyperion released the first alpha of AmigaOS 4.0 in 2004 to beta testers. The first full public release reached users in 2006.

Hyperion Entertainment are planning many more revisions and updates to AmigaOS. The authentic Amiga experience continues.
