                                WARNING
        This working version is believed to be stable, but
        we have not run our full regression-test suite.

Summary:
    Support for Intel Macs and x86-64 under Linux, a brand-new
    replacement for ml-lex, and other minor improvements as well
    as bugfixes.
Details:
  - Lexer generator:
- 
    
      - A new, much improved  lexer generator tool has been developed by
      Aaron Turon and John Reppy.  The new tool, called lexgen, can be
      used as a drop-in replacement for ml-lex.
- The compilation manager is able to have lex specification
      files processed by either lexgen or the original
      ml-lex.  For the time being, the latter is the default.
- To change this aspect of CM's behavior, invoke sml
      (and related commands such as ml-build) using the
      -Ccm.use-legacy-lex=false command line switch.
      Alternatively, one can define an environment variable
      CM_USE_LEGACY_LEX and set it to false.
- Binaries (bootfiles) shipped with this version have been
      compiled using lexgen.
    
 
- Newly supported platforms:
- 
    
      - SML/NJ builds and runs on Intel-based Macs running Mac OS X.
- SML/NJ builds and runs on x86-64 systems using 32-bit mode.
- SML/NJ should build and run on NetBSD 3.x (untested).
 
- Platforms no longer supported:
- 
    
      - Support for pre-2.2 Linux kernels has been dropped.
 
- Runtime system:
- 
    
      - Signal handling on x86/Linux has been cleaned up.
 
- MLRISC:
- 
    
      - Scripts for rebuilding MLRISC-generated files have been updated
      to reflect changes to CM.
 
- Backend:
- 
    
      - Darwin-specific Intel ABI (for foreign-function interface)
      implemented.  The solution is temporary since it currently relies
      on the fact that the compiler itself does not use the FFI.
 
- Compilation manager:
- 
    
      - Improved CM-specific error reporting and handling.
 
- Installation:
- 
    
      - Enabling $/html-lib.cm in config/preloads now works.
 
- CML:
- 
    
      - withNack wrapped around a never event will
      now properly signal the negative acknowledgement.
