<h3><a name="SF-mirror">SML/NJ web site now mirrored at SourceForge</a></h3>
<blockquote> <a name="SF-mirror">The master copy of the SML/NJ web pages
is now kept in the CVS repository of the smlnj SourceForge project (see </a><a href="#sourceforge">
previous item on SourceForge projects</a>). The <a href="http://cm.bell-labs.com/cm/cs/what/smlnj">
Bell-Labs-hosted site</a> is now joined by <a href="http://www.smlnj.org">
www.smlnj.org</a>, which mirrors the same pages from the repository.

<h3><a name="macosx">Working version 110.33 supports Mac OS X and experimentat
FFI</a></h3>
<blockquote> <a name="macosx">The recently released </a><a href="NEWS/110.33-README.html">
110.33</a> working version runs under Mac OS X. It also introduces Matthias
Blume's new, experimental FFI, NLFFI ("No-Longer Foreign Function Interface").
Currently NLFFI is available only under x86-linux, but it is being ported
to other architectures. </blockquote>

<h3><a name="smlnj.exe">New 110.0.7 smlnj.exe works on Windows 9X</a></h3>
<blockquote> <a name="smlnj.exe">The original version of the Windows
installer, smlnj.exe, for 110.0.7 had a problem when running under Windows
95/98/ME that caused error messages abound undefined strings like PRODUCT_NAME.
This problem has been corrected in a new </a><a href="ftp://ftp.research.bell-labs.com/dist/smlnj/release/110/smlnj.exe">
smlnj.exe</a> now available in the usual 110.0.7 <a href="ftp://ftp.research.bell-labs.com/dist/smlnj/release/110/">
ftp</a> and <a href="http://cm.bell-labs.com/cm/cs/what/smlnj/dist">
http</a> distribution directories.
<p> This new smlnj.exe (as of 23 March 01) also corrects a problem
where installation only set the user PATH and CM_PATH environment variables.
Now the installer sets these variables at the system level for all users.
Installation must be done from an administrator account. </p>

<h3><a name="sourceforge">New Standard ML and SML/NJ SourceForge projects</a></h3>
<blockquote> <a name="sourceforge">Two new SML-related projects have
been started at SourceForge, a site and organization supporting collaborative
development of open-source software. The </a><a href="http://www.standardml.org">
Standard ML (sml)</a> project at <a href="http://www.standardml.org">
www.standardml.org</a> supports all Standard ML implementations by encouraging
sharing of resources such as test suites, benchmarks, libraries, and documentaion.
The <a href="http://www.smlnj.org"> Standard ML of New Jersey (smlnj)</a>
project at <a href="http://www.smlnj.org"> www.smlnj.org</a> is intended
to be the future home of SML/NJ (including web pages, releases, CVS repository,
etc.). </blockquote>

<h3><a name="prog-smlnj">New SML/NJ tutorial by Riccardo Pucella</a></h3>
<blockquote> <a href="mailto:riccardo@cs.cornell.edu">Riccardo Pucella</a>
has written an extensive new tutorial, <a href="http://www.cs.cornell.edu/riccardo/smlnj.html">
<strong>Notes on Programming SML/NJ</strong></a>, which is available
as <a href="http://www.cs.cornell.edu/riccardo/prog-smlnj/notes-011001.ps">
postscript</a> or <a href="http://www.cs.cornell.edu/riccardo/prog-smlnj/notes-011001.pdf">

and suggestions. </blockquote>

<h3><a name="sml-mode">New version of sml-mode added to contrib/emacs</a></h3>
<blockquote> <a href="mailto:monnier@cs.yale.edu">Stefan Monnier's</a>
latest version, 3.9.5, of the sml-mode package for emacs has been added
to the <a href="ftp://ftp.research.bell-labs.com/dist/smlnj/contrib/emacs">
contrib/emacs</a> directory. </blockquote>
<a name="110.0.7">
<h3>Patch Release 110.0.7</h3>
</a>
<blockquote> A new minor release version <a href="NEWS/110-README.html">
110.0.7</a> is now available. This is the sixth patch release for version
110 (110.0.4 was not released). This patch release fixes a long-standing
bug in signal handling. It also includes a number of SML/NJ Library enhancements
and fixes and some fixes to CM and eXene, and a small number of other bug
fixes. See the <a href="NEWS/110-PATCH-HISTORY">110-PATCH-HISTORY</a>
file for details. With this release, we are also making the distribution
files available for download via http as well as ftp. See the <a href="dist/110.0.7.html">
110.0.7 distribution page</a>. [<strong>Note:</strong> The original smlnj.exe
installer for Windows had incorrect CM tool paths. This has been corrected
by a new smlnj.exe as of October 18, 2000.] </blockquote>
<a name="Version-111">
<h3>Plans for the next release (Version 111)</h3>
</a>
<blockquote> Meanwhile, work continues on the next release,
which we hope to have ready for a beta release "real soon now". The next
release will not contain any major language or Basis library changes, but
there will be major internal changes, including:
<ul>
<li>A new runtime system with improved management of virtual memory.
</li>
<li>New support for foreign functions (C) based on
IDL. </li>
<li>Conformance with the soon to be published SML Basis
spec. </li>
<li>MLRISC code generators for all architectures. </li>
<li>The FLINT representation has partially replaced
the old cps representation in the back end. </li>
</ul>
In addition, there will be a couple significant language extensions:
lazy datatypes and lazy functions over such datatypes, functional record
concatenation (a "with" operation), and mutable records whose fields can
be updated.
<p> Most features of Version 111 are implemented in current
working versions. The main missing elements are the new runtime system
and a MIPS code generator. </p>
</blockquote>
<h3><a href="software.html#SOFTWARE:WORKING-VERSIONS">Working
Versions</a></h3>
<p> </p>
<blockquote> <a name="110.38"> The latest working version
is </a><a href="NEWS/110.38-README.html">110.38</a>. It provides
internal improvements to MLRISC and an overhauled FFI. The previous
version (<a href="NEWS/110.37-README.html">110.37</a>) came with some enhancements
to CM and more improvements to the MLRISC backend. All working releases since
<a href="NEWS/110.35-README">110.35</a> are based on a
new organization of compiler source code into CM libraries, run under the
new Mac OS X, include Matthias Blume's new, experimental FFI (NLFFI) for
x86-linux and support CML as well as eXene.
<p> Since working version 110.9.1, major internal changes
have been implemented and many changes are still in progress. Version
<a href="NEWS/110.12-README"> 110.12</a> introduced
fundamental changes in array, vector and string representations and a new
garbage collector interface. Extensive changes have also been made to the
ML-RISC code generators. </p>
<p> Starting with <a href="NEWS/110.20-README.html">110.20</a>
, a major overhaul of the CM compilation manager has been in progress,
accompanied with a reorganization of the compiler itself into a set of
libraries. </p>
<p> The next working release will incorporate an updated
version of the FLINT middle end. At this point, we will change the way
the code is managed by having a publically accessible CVS repository at
Yale. </p>
<p> As usual, use the working versions at your own risk.
Some working versions incorporate substantial changes that reduce stability
and introduce bugs. </p>
