Dear ESS-help readers,

> The ESS Developers proudly announce the release of ESS
>    5.4

available at  http://ess.r-project.org/ from the "Download" tab.

After the long 5.3.x series, with the last previous release 5.3.11,
we have decided to simplify the numbering scheme from an x.y.z
to an x.y one.
The documentation has been re-organized partly, aiming for
improved clarity.

Also, several buglets have been fixed, for R and S, as well as
SAS and BUGS, see the *New Features* below.

For the ESS core team,
Martin Maechler, ETH Zurich

The rest of the 'ANNOUNCE' file :

   Emacs Speaks Statistics (ESS) provides an intelligent, consistent
interface between the user and the software.  ESS interfaces with
S-PLUS, R, SAS, BUGS and other statistical analysis packages under the
Unix, Microsoft Windows, and Apple Mac OS operating systems.  ESS is a
package for the GNU Emacs and XEmacs text editors whose features ESS
uses to streamline the creation and use of statistical software.  ESS
knows the syntax and grammar of statistical analysis packages and
provides consistent display and editing features based on that
knowledge.  ESS assists in interactive and batch execution of
statements written in these statistical analysis languages.

   ESS is freely available under the GNU General Public License (GPL).
Please read the file COPYING which comes with the distribution, for
more information about the license. For more detailed information,
please read the README files that come with ESS.

1.1 Getting the Latest Version

The latest released version of ESS is always available on the web at:
ESS web page (http://ess.r-project.org) or StatLib

   The latest development version of ESS is available via
`https://svn.R-project.org/ESS/', the ESS Subversion repository.  If
you have a Subversion client (see `http://subversion.tigris.org/'), you
can download the sources using:
     % svn checkout https://svn.r-project.org/ESS/trunk PATH
   which will put the ESS files into directory PATH.  Later, within
that directory, `svn update' will bring that directory up to date.
Windows-based tools such as TortoiseSVN are also available for
downloading the files.  Alternatively, you can browse the sources with a
web browser at: ESS SVN site (https://svn.r-project.org/ESS/trunk).
However, please use a subversion client instead to minimize the load
when retrieving.

   If you remove other versions of ESS from your emacs load-path, you
can then use the development version by adding the following to .emacs:

     (load "/path/to/ess-svn/lisp/ess-site.el")

   Note that https is required, and that the SSL certificate for the
Subversion server of the R project is

     Certificate information:
      - Hostname: svn.r-project.org
      - Valid: from Jul 16 08:10:01 2004 GMT until Jul 14 08:10:01 2014 GMT
      - Issuer: Department of Mathematics, ETH Zurich, Zurich, Switzerland, CH
      - Fingerprint: c9:5d:eb:f9:f2:56:d1:04:ba:44:61:f8:64:6b:d9:33:3f:93:6e:ad

(currently, there is no "trusted certificate").  You can accept this
certificate permanently and will not be asked about it anymore.

1.3 Requirements

ESS is most likely to work with current/recent versions of the following
statistical packages: R/S-PLUS, SAS, Stata and JAGS. The one exception
is BUGS which is quite old, but should still work.

   ESS supports current/recent versions of GNU Emacs and XEmacs.  Most
notably, the GNU Emacs 22 series and XEmacs 21.4.14 or higher
(beta/pre-release versions are NOT SUPPORTED).

1.4 Stability

Versions 5.3.x are meant to be release-quality versions.  While some
new features are being introduced, we are cleaning up and improving the
interface.  We know about some remaining documentation inconsistencies.
Patches or suggested fixes with bug reports are much appreciated!

1.5 Mailing List

There is a mailing list for discussions and announcements relating to
ESS.  Join the list by sending an e-mail with "subscribe ess-help" (or
"help") in the body to <ess-help-request at stat.math.ethz.ch>;
contributions to the list may be mailed to
<ess-help at stat.math.ethz.ch>.  Rest assured, this is a fairly
low-volume mailing list.

   The purposes of the mailing list include

   *  helping users of ESS to get along with it.

   *  discussing aspects of using ESS on Emacs and XEmacs.

   *  suggestions for improvements.

   *  announcements of new releases of ESS.

   *  posting small patches to ESS.

1.6 Reporting Bugs

Please send bug reports, suggestions etc. to
<ESS-bugs at stat.math.ethz.ch>

   The easiest way to do this is within Emacs by typing

   `M-x ess-submit-bug-report'

   This also gives the maintainers valuable information about your
installation which may help us to identify or even fix the bug.

   If Emacs reports an error, backtraces can help us debug the problem.
Type "M-x set-variable RET debug-on-error RET t RET".  Then run the
command that causes the error and you should see a *Backtrace* buffer
containing debug information; send us that buffer.

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

1.9 New Features

     Changes/New Features in 5.4:
        * ESS[SAS]: The long overdue change from `make-regexp' to
          `regexp-opt' for font-locking is complete.  The new
          `regexp-opt' is now the default since it is better than the
          old code in many ways (and especially more maintainable).
          However, there are certainly some special cases missed (bug
          reports and patches welcome!).  Setting
          `ess-sas-run-regexp-opt' to `nil' will result in the old code
          being used.

        * ESS[BUGS] and ESS[JAGS]: typing `=' now results in  `<-'.

        * ESS[R] function arguments "show" `(ess-r-args-show)' now
          uses the new `(tooltip-show-at-point)' contributed by Erik

        * Toolbar icons now also work in (beta) Emacs 23.

        * ESS[S]: New function `ess-change-directory' for setting both
          emacs' current directory and the directory of an *R* or *S*

        * ESS[S] when transient-mark-mode is true, the mark is now kept,
          rather than deactivated, thanks to a patch from David Reitter.

     Changes/New Features in 5.3.11:
        * ESS[SAS]: work around bug in Emacs 22.2 & 22.3 which fails to
          set case-fold fontification automatically.

        * Rd mode: support new keyword 'Rdversion'

        * ESS[R]: now again works with Emacs 21.x

     Changes/New Features in 5.3.10:
        * Fixed noweb-mode bug accidentally introduced into 5.3.9

        * In noweb-mode, e.g., Rnw-mode, electric "<" also inserts
          closing "@".   Further, the code chunk boundaries are better
          kept up-to-date, such that  code[R] <-> text[LaTeX] minor
          mode switching should happen more reliably.

        * In noweb-mode, fix a buglet in rare [Enter] or [Tab]
          behavior; further,  by default disable the former `[[' ..
          `]]'  code-protection-when-filling  behavior which has been
          found to be buggy.

     Changes/New Features in 5.3.9:
        * ESS[SAS]: evince PDF viewer now supported as well; search
          order: evince, Xpdf, Adobe/Acrobat Reader

        * ESS[R]: added support for Roxygen, potentially to be extended.

        * ESS[S] (and R): inferior (`*R*') and transcript modes no
          longer fontify language keywords (such as `for', `in', etc).

        * iESS[Stata]: Customize the `ess-sta-delimiter-friendly'
          setting to `t' to convert embedded semi-colons to newlines
          for Stata processing.

        * Sweave fix for embedded blanks in PDF reader and PDF files

        * Several fixes for Major Mode Convention violations in
          `ess-mode' and `noweb-mode'.

        * ESS[JAGS]: `M-x comment-region' now available!

        * ESS[S] The `ess-swv-*' commands (and keybindings) are now in
          a submenu of the "Noweb" menu, when editing Sweave files.

     Changes/New Features in 5.3.8:
        * ESS[JAGS]: more separation from ESS[BUGS] (as much as is
          currently planned); now `C-c C-c' on an empty `.jmd' creates
          a template as it should; symbolic links are created for CODA
          output so BOA is happy: from `index.txt' to `.ind' and
          `chain#.txt' to `#.out'

        * ESS[SAS]: buffer-local `ess-sas-submit-command' and
          `ess-sas-submit-command-options' now recognized by

        * ESS[S]: When trying to evaluate code in an S language buffer
          and  there is no associated process, now start R
          automatically instead of  signalling an error.  Also, restart
          R if there is an associated process  which is not running.
          However, do not start R just via the "electric"  `('

        * ESS[S]: For (one-line) functions withOUT '{ .. }' bodys, the
          end  of function is now correctly found more often.  This
          notably improves  `C-c C-c'

        * ESS[JAGS]: cleanup/re-organization of elisp code; symbolic
          links for CODA output are now only created by the new JAGS
          `system' command in version 1.0.3; specify whether this
          command is available via `ess-jags-system'; if not present,
          then no links are created so that the `*shell*' buffer does
          not become unresponsive during the batch run

     Changes/New Features in 5.3.7:
        * ESS: `ess-default-style' now *is* customizable, i.e.,
          changing its value in `~/.emacs' now does have the desired

        * ESS: `ess-font-lock-mode' is a new variable (default: t)
          which controls whether font-locking is enabled in ESS buffers.

        * ESS[R]: for XEmacs on Windows; another tweak to find R

        * ESS[SAS]: font-locking updated for ODS and SAS Bayesian
          Procedures; a more consistent handling of SAS options by
          `ess-sas-submit-command-options' which is buffer-local;
          portable snooze for MS Windows via customize-able
          `ess-sleep-for' (floats welcome); Xpdf now supported as a PDF

        * ESS[Rnw]: now also works with "emacs -nw" and Emacs 22.

        * ESS[JAGS]: now requires JAGS 1.0 (see the new ESS for JAGS
          help section for more information): both need work;
          suggestions welcome

        * ESS[R]: [TAB] completion now uses the R-internal completion
          mechanism (for R >= 2.5.0).

        * ESS[R] ([S]): interpretation of "_" as assignment has been
          removed in `ess-continued-statement-p' for R and S.

        * several internal code cleanups.

        * ESS[R]: An experimental version of a new command `Rgui' on MS
          Windows to send lines directly from emacs to `Rgui' is
          available in file `lisp/essd-rgui.el'.  Preliminary
          documentation is in file `doc/rgui-doc.txt'.

     Changes/New Features in 5.3.6:
        * ESS: for XEmacs, using "gnuclient" (without a "-q") works for
          things like fix() after M-x gnuserv-start has been done.

        * ESS[R]: M-x R-newest should now work in more situations on MS
          Windows, e.g., when R has been installed in a non-default
          "ProgramFiles"  directory tree.  In these cases, there's no
          need to specify the name (and  full path) of the R program

        * ESS[R]: For XEmacs, startup (with new tooltip code) works

     Changes/New Features in 5.3.5:
        * ESS[R] a new defun is available, `M-x R-newest', which will
          start the newest version of R that it can find on your system.

        * ESS[R] add Sven Hartenstein's "R function arguments tips"
          functionality, via new file `../lisp/essd-r-args.el'.   Note
          that this includes an "electric "("" behavior inside `R-mode'
          which is _active by default_ and can be customized via
          `ess-r-args-electric-paren'; i.e., use `(setq
          ess-r-args-electric-paren nil)' to turn it off.  Further,
          `ess-r-args-show-as' allows to switch to the "tooltip" mode.

        * ESS: functions `ess-get-pdf-viewer' and *-ps-viewer; built on
          new  customizable variables `ess-pdf-viewer-pref' and
          `ess-ps-viewer-pref'; currently used in `ess-swv-PDF' and

        * ESS[R] Improved `ess-swv-PDF' to run pdf viewer only if
          pdflatex was ok

        * ESS[R] Improved `ess-swv-weave' to start R automatically if
          none is running.

        * ESS: Do no longer ask _which_ ESS process to use if there  is
          only one.

     Changes/New Features in 5.3.4:
        * ESS[R] now better work with options(error=recover); and the
          new default of CHM help files on windows.

        * ESS[R] some more cleanup in the "sweave" functions

        * miscellaneous fixes

     Changes/New Features in 5.3.3:
        * ESS[S] fix buglet (5.3.2 only) which left command prompt in
          "execute buffer" and hence help files.

        * new customizable variable `ess-display-buffer-reuse-frames'
          set to true (which changes default behavior) such that
          execution or help *frames* are reused.

     Changes/New Features in 5.3.2:
        * Classic BUGS now supported by `(require 'essd-bugs)' with
          ESS[BUGS]       and JAGS by `(require 'essd-jags)' with
          ESS[JAGS].  But, only one       of them can be used at a time
          since they don't play nice together.  Also,       `C-c C-c'
          is now bound to the function `ess-bugs-next-action'
          (`F12' has been retired).  And finally, note that
          `essl-bug.el'       is deprecated and the replacement is

        * ESS[R] Improved some of the "Sweave-make"  functions (yet
          scarcely documented) in `ess-swv.el'.

        * ESS[S] No longer mess with .Last.value (nor in other

     Changes/New Features in 5.3.1:
        * See the docs for 2 ways to install ESS for XEmacs
            1. by uncommenting the XEmacs part of             Section 1
               of `Makeconf' and performing `make install'

            2. by unpacking either             `ess-5.3.1.tgz' or
               `ess-5.3.1.zip' into
               `PREFIX/lib/xemacs/site-packages' on unix or
               `PREFIX\XEmacs\site-packages' on windows

        * ESS[R]: fixed bugs so that Rterm.exe can be found by XEmacs

        * ESS[S]: `ess-toggle-S-assign-key' is slightly changed; in
          particular, the default `ess-assign-key' is now `C-x ='.

        * ESS[R]: `M-x R-site-search' is a new (slightly experimental)
          utility similar to R's `RSiteSearch(..)' but with the
          advantage of  using Emacs' preferred browser, see

     Changes/New Features in 5.3.0:
        * ESS[BUGS]: sanely re-format statistical output, `.bog', from
          scientific notation to numbers rounded with 4 decimal places
          with `M-x ess-bugs-sci-round-to-4-dp'.

        * The keys for navigating among section headings in help buffers
          worked, but only for one language per session; they should
          now work for multiple languages.  (They were also broken on
          Windows machines.)

        * ESS[S] long standing buglets in the internal logic for loading
          lisp code on Windows.  Particularly fixed behavior in help
          mode with S-plus GUI.

        * New variable, `ess-use-inferior-program-name-in-buffer-name',
          which enables using the executable name instead of the
          dialect name for R. Feature request.

        * ESS[S] `ess-execute-screen-options' now also works correctly
          when there is more than one window *side-by-side* in the same
          frame and runs in the correct buffer also when there is more
          than one S buffer.

        * iESS[S] new functions `ess-eval-paragraph-and-step' and
          `ess-eval-function-or-paragraph-and-step' are bound to keys
          `C-c C-p' and `C-c C-c' respectively and to the menu in
          ESS-mode; also bound in the help mode (for evaluating

        * ESS[S] new function `ess-toggle-S-assign-key' allows to
          assign the " <- " insertion to an arbitrary key.
