+Around 1993/1994 [Apple] decided that they needed a more modern version of [MacOS]. They announced that they were starting work on two new [OperatingSystem]s , Copland which would be released in 1996 as MacOS 8 and [Gershwin] estimated to come out in 1998 as MacOS 9. 
  
 The [Macintosh] hardware market at the time was relatively unstable with [Apple] licencing [MacOS] to third parties and [RAM] prices were fluctuating wildy and as such the goals of Copland changed a number of times during development. The main feature of Copland was the !NuKernel. This was to add PreemptiveMultitasking, MemoryProtection, SymmetricMultiProcessing and substantially improved VirtualMemory support into [MacOS]. Additional features of note were a fully Power PC Native OperatingSystem, robust [Theme] support, [MultiUser] support, Quickdraw3D, a new filesystem (HFS+), advanced !OpenTransport networking, the (V-Twin) search engine and !OpenDoc, a powerful ComponentArchitecture. 
  
 In order to support these features, a number of old and obsolete [API]'s were removed from [MacOS], mostly relating to task management and memory management. [Apple] claimed that 70% of the software available at the time would run on the new OperatingSystem with the remaining software requiring source code changes.
