AmigaOS 4.5

AmigaOS4.5 represents the final stage in the creation of a native PPC OS. Its tasks include;

• All remaining 68k OS code to be converted to PPC native
• All hardware features of the zico specification to be made accessible to developers
• New user environment

AmigaOS 5

AmigaOS5 represents a revolution in the development of 'other' operating systems and the evolution of the AmigaOS as it seeks to provide the best way forwards for users and developers. Its feature set includes;

• Brand new services model providing
  • Virtual Memory
  • Memory Protection
  • Symmetric and Asymmetric modes
  • Contract QoS
  • 64 bit
  • Fully distributed
• AmigaOS4 sandbox
• PDP sensory processing system - PDP stands for Physical to Digital to Physical and provides a scalable system that provides for capture, conversion, representation, manipulation and presentation of sense delimited observation and interaction
• Orthogonal Persistence - all content is persistent, instead of having to be saved to and loaded from storage.
• Safe and Unsafe environments - separate memory spaces in which developers can continue to use unsafe languages or develop using the new SafeC language and environment.
• Semantic Context - an environment is which the user can layer any number of associations, relationships and meaning to their environment and content, and use that semantic information to organize and query.

Amiga OS 5 represents a big step for the Amiga OS and will finally be in the lead of the OS wars. This is not going to be out until 2003 so we got a bit of wait on our hands.
