I'm releasing ESS 5.1.17 .   This is a testing release, to see if a
critical change (defining variables to be modifiable by "customize")
breaks anything else.  

I highly recommend against removing your working version of 5.1.16 in
favor of this, especially in a production/working environment.  On the
other hand, it would do the ESS developers a good deal of good to hear
verified reports of this NOT breaking your system.

Here's the release announcement.


   Annoucing the release of ESS-5.1.17 (Emacs Speaks Statistics).

   ESS is an Emacs package which provides a standard interface between
statistical programs and statistical processes.  It is intended to
provide assistance for interactive statistical programming and data
analysis, and was is based on and extends the capabilities of S-mode.

   The code is freely available but is not in the public domain.  It is
distributed under the GNU GPL.  Please read the file COPYING which comes
with the distribution, for more information about the license.

   For more detailed information about ESS's abilities, please read the
file README with the distribution.

   And to help remove any further confusion:

   	The name is __ESS__.  Not ESS-mode.

   Thank you :-).

New Features

   Changes/New Features in 5.1.17:
   * Documentation for Windows Installation (Rich Heiberger
     (<rmh at>))

   * removal of ess-vars, finalization of customize support (in the
      sense that there is no more use of ess-vars, but that we need to
          fix ess-cust) (AJ Rossini (<rossini at>))

   * Many small (and large) fixes/contributions (MMaechler,
     (<maechler at>)).

   * addition of the "S-equal" variable and provide M-x ess-add-MM-keys
          a way to remap "_" to 'S-equal, typically " <- ", but
     configurable. (MMaechler, (<maechler at>)).

   Changes/New Features in 5.1.16:

   * Better SAS support

   Changes/New Features in 5.1.15:

   Changes/New Features in 5.1.14:
   * Yet more fixes to SAS mode, (Rich Heiberger
     (<rmh at>) and Rodney Sparapani
     <spara002 at>)).

   * Customize support (for most Emacsen which support it) (AJRossini,
         (<rossini at>)

   * ARC and ViSta support out of the box, and fixes for XLispStat
     (AJRossini,       <rossini at>)

   Changes/New Features in 5.1.13:
   * Version numbering finally all depending on the ./VERSION file,
      thanks to Martin Maechler.

   * Yet more fixes to SAS mode, thanks to Rich Heiberger
     (<rmh at>).

   Changes/New Features in 5.1.12:
   * Splus 5.1 stabilized, thanks to Martin Maechler, Bill Venables,
       Chuck Taylor, and others.

   * More fixes to SAS mode, thanks to Rodney Sparapani
     (<spara002 at>) and Rich Heiberger
     (<rmh at>).

   Changes/New Features in 5.1.11:
   * More fixes to Stata mode, thanks to Brendan Halpin
     (<brendan at>)

   * fixed bugs in ESS-elsewhere, thanks to many testers

   * README.SPLUS4WIN has DETAILED instructions for S-PLUS 2000, thanks
          to David Brahm (<brahm at>).

   * Fixes to SAS mode, thanks to Rodney Sparapani
     (<spara002 at>)

   Changes/New Features in 5.1.10:
   * More fixes to Stata mode

   * primitive generic version of ESS-elsewhere

   * Small fixes to SAS/Stata.

   Changes/New Features in 5.1.9:
   * Stata mode works

   * Literate Data Analysis using Noweb works

   Changes/New Features in 5.1.8:
   * Bug fixes

   * R documentation mode defaults changed

   Changes/New Features in 5.1.2:
   * able to use inferior iESS mode to communicate directly with a
     running S-Plus 4.x process using the Microsoft DDE protocol.  We
     use the familiar (from Unix ESS) C-c C-n and related key sequences
     to send lines from the S-mode file to the inferior S process.  We
     continue to edit S input files in ESS[S] mode and transcripts of
     previous S sessions in ESS Transcript mode.  All three modes know
     the S language, syntax, and indentation patterns and provide the
     syntactic highlighting that eases the programming tasks.

Current Features

   * Languages Supported:
        * S dialects (S 3/4, S-PLUS 3.x/4.x/5.x, and R)

        * LispStat dialects (XLispStat, ViSta under development)

        * SAS

        * Stata

        * SPSS dialects (SPSS, Fiasco (GNU project)) (under development)

        * SCA (under development)

   * Editing source code (S, LispStat, SAS)
        * Syntactic indentation and highlighting of source code

   Versions 5.1.x are meant as a beta-level releases.  While some bugs
are fixed from 5.0, others have been introduced, especially with
regards to new features.  See the file Doc/TODO for details.  Bug
reports are solicited; see the BUGS section below.  Patches or
suggested coding fixes with bug reports are much appreciated!

   Some versions tend to be more stable than others, and for new support
(Microsoft support), 5.1.16 is the current favorite.


   ESS version 5.1.n (n >= 2) requires Emacs version 19.29 or later, or
version XEmacs 19.14 or later.  It has been most thoroughly tested with:

   * S-PLUS versions 3.3, 3.4, 4.5, 5.0

   * R versions >=0.49

   * XLispStat versions >=3.50

   * S4

   * SAS

   * Stata >=6.0

   on the following platforms

   * SunOS (all)

   * Solaris (all)

   * SGI (all)

   * Linux (S-PLUS 5.0, R, XLispStat, S4, Stata 6.0)

   * Microsoft Windows 95/98/NT (SPLUS 4.5)

   with the following Emacsen:

   * Emacs 19.29, 19.34, 20.3, 20.4, XEmacs 19.16, XEmacs 20.4, XEmacs

   * Emacs 19.28 with SAS (with additional modifications)

   * NTEmacs 20.3.1 with S-PLUS 4.5.

   It may need some work with other configurations.  We include
configuration suggestions for emacs 19.28 in Doc/README-19.28.  These
are the changes we made in order to use ESS with SAS on a Digital Alpha
running Emacs 19.28.

installation which may help us to identify or even fix the bug.

   Note that comments, suggestions, words of praise and large cash
donations are also more than welcome.
