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

    Support for Intel Macs and x86-64 under Linux, a brand-new
    replacement for ml-lex, and other minor improvements as well
    as bugfixes.


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.


  - Scripts for rebuilding MLRISC-generated files have been updated
    to reflect changes to CM.


  - 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.


  - Enabling $/html-lib.cm in config/preloads now works.


  - withNack wrapped around a never event will now properly
    signal the negative acknowledgement.
