                                WARNING

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

Summary:

   This release fixes important bugs and provides some additional
   functionality.

--------------------------------------------------------------------------

Details:

Basis:
------

  - Added specialized implementation of Int31.fromString.

MLRISC:
-------

  - Fixed bugs in x86/c-calls related to passing structs as arguments
    or results.
  - Fixed bug in x86 assembly syntax (FU?COMIP?).

Libraries:
----------

  - Minor enhancements to interfaces exported from the "controls"
    library.
  - Added libraries $smlnj-tdp/plugins.cm, $smlnj-tdp/back-trace.cm,
    and $smlnj-tdp/coverage.cm.  This moves back-trace support out of
    the main compiler and into a library of trace/debug/profile plugins.
    The test-coverage plugin is new.

Command-line:
-------------

  - Added flags "-e" and "-E" which print the names of environment
    variables that can be used to control internal settings.
  - Added support for tracing, debugging, and profiling (using
    stuff from $smlnj-tdp/plugins.cm) for stand-alone programs.
    (Stand-alone programs are those constructed using ml-build.)

Runtime:
--------

  - Applied patch for setting rounding modes under Mac OS X.

Compiler:
---------

  - PPC backend now silent (by default) even when it uses the "long
    form of branch".
  - Made the former backtrace-instrumentation pass more generic.
  - Some internal cleanup (consolidation of duplicated functionality).

Compilation Manager:
--------------------

  - Direct support for lazy sml (keyword "lazy") via new toolclass
    "lazysml" and filename suffix ".lml".
  - Support for selectively setting arbitrary control flags on
    a per-sourcefile basis.
  - Fixed handling of CM keywords, thereby eliminating a bug with
    the shell tool.
  - CM now issues an "obsolete feature" warning when group files
    use the old "owner" syntax.

Bootstrap compiler:
-------------------

  - Adde a "version tool" and some CM magic to have the file version.sml
    be auto-generated during CMB.make.
  - Moved version.sml (and above-mentioned magic) into its own library.
