Introduction

Traditionally NetHack has had as a goal to run on as many different machines, architectures, operating systems, and window systems as possible. However, from time to time it becomes necessary to drop support for things that no one is able to support. It's unfortunate, but if we can't test it or it prevents us from moving forward, we have to do it.

Deprecations update for NetHack 5.0.0

• The Amiga port has been brought back.
• Clarification: 16-bit MS-DOS has been dropped (32-bit protected mode is still supported).
• We did not drop Bitfield.
• The code base is moving to C99. We are no longer attempting to track individual features.

Deprecations announced with NetHack 3.6.1

• Support for the following will be dropped from the next major release unless someone comes forward to maintain them:
  
  • Amiga
  • Atari
  • Macintosh Classic
  • BeOS
  • OS/2
  • 16-bit MS-DOS
  • Floppy disk support for all platforms
• Starting with the next major release, we will be dropping support for most K&R and pre-ANSI C features, including:
  
  • the Bitfield macro
  • K&R function definitions
• Starting with the next major release, we will start using ANSI C features; which ones have yet to be determined.
  If you are actively running NetHack on a system that cannot handle full ANSI C, please let us know some details and we _might_ be able to accommodate you.
