AmigaOS 4.0 GUI: Workbench 4.0[5]

A new version of AmigaOS was released on December 24, 2006 after five years of development by Hyperion Entertainment (Belgium) under license from Amiga, Inc. for AmigaOne registered users.

During the five years of development, users of AmigaOne machines could download from Hyperion repository Pre-Release Versions of AmigaOS 4.0 as long as these were made available. As witnessed by many users into Amiga discussion forum sites, these versions were stable and reliable, despite the fact that they are technically labeled as "pre-releases".

The last stable version of AmigaOS 4.0 for AmigaOne computers is the "July 2007 Update", released for download 18 July 2007 to the registered users of AmigaOne machines.[1]

AmigaOS 4 Classic was released commercially for older Amiga computers with CyberstormPPC and BlizzardPPC accelerator cards in November 2007. It had previously been available only to developers and beta-testers.

4.0 versions

[edit]

The new version is PowerPC-native, finally abandoning the Motorola 68k processor. AmigaOS 4.0 will run on some PowerPC hardware, which currently only includes A1200, A3000 and A4000 with PowerPC accelerator boards and AmigaOne motherboards. Amiga, Inc.'s distribution policies for AmigaOS 4.0 and any later versions require that for third-party hardware the OS must be bundled with it, with the sole exception of Amigas with Phase 5 PowerPC accelerator boards, for which the OS will be sold separately.

AmigaOS 4.0 Final introduced a new memory system based on the slab allocator.

Features, among others:

Developer pre-releases

[edit]

AmigaOS 4.0 (Developer Pre-release)

[edit]

The developer pre-release version was a snapshot of AmigaOS 4.0 for AmigaOne. It contained HTML installation guide in English, German, French and Italian and the AmigaOS 4.0 SDK.

The AmigaOS 4.0 SDK[1] allowed creation of new software and migration of existing AmigaOS versions 3.x source code to OS 4.0.
