                                 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.
