Dear ESS users and lovers,

As we have had quite a few smallish but not unimportant
improvement requests / bug fixes,
a few minutes ago, we have released the third patch version of
ESS 12.04, i.e. '12.04-3'.

As usually you can download it from the  ESS  homepage
(direct link http://ess.r-project.org/index.php?Section=download  ).

For the ESS core team:
Martin Maechler, ETH Zurich

Here are parts of the 'ANNOUNCE' file which is part of the distribution:

The ESS Developers proudly announce the release of ESS


   Emacs Speaks Statistics (ESS) provides an intelligent, consistent
interface between the user and the software.  ESS interfaces with
R/S-PLUS, SAS, BUGS/JAGS, Stata and other statistical analysis packages
under the UNIX, GNU Linux, Microsoft Windows, Mac OS X and other
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.

1.3 Requirements

ESS is most likely to work with current/recent versions of the following
statistical packages: R/S-PLUS, SAS, Stata, OpenBUGS and JAGS.

   ESS supports current, and recent, stable versions of GNU Emacs
(specifically, the 22.x and 23.x series; alpha/beta/pre-release versions
are NOT SUPPORTED).  XEmacs currently does not allow all ESS features.
Basic ESS functionality however is supported for the time being (XEmacs
stable 21.4.14 or higher).

   To build the PDF documentation, you will need a version of TeX Live
or texinfo that includes texi2dvi (BEWARE: recent TeX Live, and some
texinfo RPMs, do NOT include texi2dvi).

1.4 Stability

All recent released versions are meant to be release-quality versions.
While some new features are being introduced, we are cleaning up and
improving the interface.  We know that there are many remaining
opportunities for documentation improvements, but all contributors are
volunteers and time is precious. 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/Bug Fixes in 12.04-3:
        * ESS: basic support for package.el compatibility

        * ESS[R]: correct indentation of & and | continuation lines

        * `M-x ess-version' shows the svn revision even after `make

        * ESS[SAS]: improved XEmacs support

        * iESS[R]: better finding of previous prompt

        * ESS[Stata]: adjusted prompt for mata mode

        * ESS[R]: resolved name clashes with cl.el

        * ESS[R]: removed dependence on obsolete package assoc

        * New `make' target  `lisp', to build the lisp-only part, i.e.,
          not building the docs.

     Changes/New Features in 12.04-1:
        * iESS[Stata]: New interactive help invocation.

        * iESS[Stata]: New custom variable `inferior-STA-start-file'.

        * iESS[Stata]: `inferior-STA-program-name' is now "stata" and
          can be  customized.

        * ESS[Stata] New sections in stata help files Syntax(`s-S'),
          Remarks(`r'), Title(`t').

     Bug Fixes in 12.04-1:
        * ESS[R]: Better `ess-tracebug' error handling.

        * ESS[R]: Corrected `ess-eldoc' help string filtering and
          improved argument caching.

        * ESS[R]: Indentation of non-block if/else/for/while lines

        * `M-x ess-version' should work better.

        * ESS: Filename completion now again works inside strings.

        * iESS[Stata]: Fixed prompt detection issue.

        * ESS[Rd]: R is autostarted also from here, when needed.

     Changes/New Features in 12.04:
        * ESS: Reverting new behavior of 12.03, `TAB' in `ess-mode' no
          longer completes by default.  If you want smart `TAB'
          completion in R and S scripts, similarly to iESS behavior,
          set the variable `ess-tab-complete-in-script' to `t'. Also see
          `ess-first-tab-never-complete' for how to customize where
          first `TAB' is allowed to complete.

        * ESS: completion is consistently bound to `M-TAB' (aka `M-C-i')
          in both Emacs23 and Emacs24.

        * ESS: The variable `ess-arg-function-offset-new-line'
          introduced in ESS(12.03) now accepts a list with the first
          element a number to indicate that the offset should be
          computed from the indent of the previous line. For example
          setting it to '(2) results in:

            a <- some.function(

     Changes/New Features in 12.03:
        * ESS indentation: new offset variable
          `ess-arg-function-offset-new-line' controlling for the
          indentation of lines immediately following open '('. This is
          useful to shift backwards function arguments after a long
          function call expression:

            a <- some.function(

          instead of the old

            a <- some.function(

          If '(' is not followed by new line the behavior is unchanged:

            a <- some.function(arg1,

          This variable should be set as part of indentation style
          lists, or in ess-mode hook.

        * ESS[R]: `C-c .' sets (indentation) style.

        * ESS: In ESS buffers `yank'(`C-y') command accepts  double
          argument `C-u C-u' to paste commands only. It deletes any
          lines not beginning with a prompt, and then removes the
          prompt from those lines that remain. Useful to paste code
          from emails, documentation, inferior ESS buffers or
          transcript files.

        * Documentation: ESS user manual has been rearranged and
          completed with several new chapters and sections to reflect
          newly added features ("Completion", "Developing with ESS",
          "ESS tracebug", "ESS developer", "ESS ElDoc", "IDO
          Comppletion" and "Evaluating Code")

        * RefCard: Reference card was updated to include new features.

        * Eldoc: Eldoc was rewritten and is activated by default.  See
          `ess-use-eldoc', `ess-eldoc-show-on-symbol',
          `ess-eldoc-abbreviation-style' variables for how to change
          the default behavior. _Note:_ `skeleton-pair-insert-maybe'
          prohibits eldoc display, on `(' insertion.

        * ESS[R]: Eldoc shows arguments of a generic function whenever

        * ESS: `TAB' in `ess-mode' now indents and completes, if there
          is nothing to indent. Set `ess-first-tab-never-completes-p'
          to `t' to make `TAB' never complete on first invocation.
          Completion mechanism is similar to the completion in the
          `inferior-ess-mode' - a filename expansion is tried, if not
          found ESS completes the symbol by querying the process.

        * ESS for emacs version 24 or higher: ESS is  fully compatible
          with the emacs 24 completion scheme, i.e. all the completion
          is done by `completion-at-point'. Also in accordance with
          emacs conventions, ESS doesn't bind `M-TAB' for emacs 24 or
          higher. `M-TAB' calls the default `complete-symbol'.

        * ESS[R]: Out of the box integration with `Auto Completion'
          mode (http://cx4a.org/software/auto-complete/). Three AC
          sources `ac-source-R-args', `ac-source-R-objects' and
          `ac-source-R' are provided. The last one combines the
          previous two and makes them play nicely together. Set
          `ess-use-auto-complete' to `t' to start using it.  Refer to
          documentation string of `ac-use-auto-complete' for further

        * ESS[R]: New unified and fast argument completion system,
          comprised of `ess-funname.start', `ess-function-arguments',
          `ess-get-object-at-point'. Eldoc and auto-completion
          integration are using this system.

        * ESS: `ess-switch-to-end-of-ESS'(`C-c C-z'), and
          `ess-switch-to-ESS'(`C-c C-y'): Automatically start the
          process whenever needed.

        * ESS[R]: `roxy' knows about previewing text version of the
          documentation. Bound to `C-c C-e t'.

        * ESS[R]: Solved the "nil filename" bug in roxygen support.

        * ESS[R]: `ess-tracebug' is now part of ESS:

          New Features:

             - Source injection: Tracebug now can inject source
               references on the fly during code evaluation, i.e. you
               don't have to source your file, but just evaluate your
               code in normal fashion. Variable
               `ess-tracebug-inject-source-p' controls this behavior -
               if t, always inject source reference, if `'function',
               inject only for functions (this is the default), if
               `nil', never inject.

               During the source injection the value of
               `ess-eval-visibly-p' is ignored.

             - Org-mode support: Visual debugger is now aware of the
               temporary org source editing buffer (`C-c '') and jumps
               through this buffers if still alive, or in original org
               buffer otherwise.

             - New keys in watch mode: `?' and `d'

             - Two new hooks: ess-tracebug-enter-hook and

        * ESS[R]: New package `ess-developer' to evaluate `R' code
          directly in the package environment and namespace. It can be
          toggled on and off with `C-c d t'. When `ess-developer' is on
          all ESS evaluation commands are redefined to evaluate code in
          appropriate environments. Add package names to the list of
          your development packages with `C-d a', and remove with `C-d
          r'. Source the current file with `C-d s'.Evaluation function
          which depend on ``ess-eval-region'' ask for the package to
          source the code into, `ess-eval-function' and alternatives
          search for the function name in the development packages'
          environment and namespace and insert the definition
          accordingly. See the documentation section "Developing with
          ESS/ESS developer" for more details.

        * ESS[R] help system:

          New Features:

             - `q' quits window instead of calling
               `ess-switch-to-end-of-ESS'.  This is consistent with
               emacs behavior help and other special buffers (_breaking

             - `k' kills window without asking for the name (pointed by
               Sam Steingold)

             - Help map inherits from `special-mode-map' as sugested by
               Sam Steingold.

             - Package index: new function `ess-display-index' bound to
               `i' in help mode map.

             - Package vignettes: new function `ess-display-vignettes'
               bound to `v' in help mode map.

             - Display help in HTML browser: new function
               `ess-display-help-in-browser' bound to `w' in help mode
               map. It depends on `R''s `browser' option.

             - New custom variable `ess-help-pop-to-buffer': if non-nil
               ESS help buffers are given focus on display. The default
               is `t' (_breaking change_).

             - New menu entries for the above functions.

             - Bogus help buffers are no longer generated by default,
               i.e.  buffers of the form "No documentation for 'foo' in
               specified packages and libraries: you could try '??foo'
               ".  `ess-help-kill-bogus-buffers' now defaults to `t'.
               Beware, there may be instances where the default is
               unsatisfactory such as debugging and/or during R
               development.  Thanks to Ross Boylan for making the
               suggestion, Sam Steingold for reminding us of this
               variable and Martin Maechler for the warning.

        * ESS now uses `IDO' completing read functionality for all the
          interactive requests. It uses ido completion mechanism
          whenever available, and falls back on classical
          completing-read otherwise. You can set `ess-use-ido' to nil
          if you don't want the IDO completion. See the documentation
          string of `ess-use-ido' for more information about `IDO' and
          ESS configuration.

        * ESS[S]: "`,'" is bound to ess-smart-comma: If comma is
          invoked at the process marker of an ESS inferior buffer,
          request and execute a command from ``ess-handy-commands''
          list. If `ess-R-smart-operators' is t ``ess-smart-comma' also
          inserts " " after comma.

        * ESS[S], notably `R': Variable ``ess-handy-commands'' stores
          an alist of useful commands which are called by
          `ess-smart-comma' in the inferior buffer.

          Currently containing:












          Handy commands: `ess-library', `ess-install.packages', etc -
          ask for item with completion and execute the correspond
          command. `ess-sos' is a interface to `findFn' function in
          package `sos'. If package `sos' is not found, ask user for
          interactive install.

        * ESS: New dynamic mode line indicator: Process status is
          automatically reflected in all mode-lines of associated with
          the process buffers. Particularly useful for displaying debug
          status of `ess-tracebug' and developer status of
          `ess-developer' in all associated buffers.

        * ESS: New `ess-completing-read' mechanism: ESS uses `ido'
          completions whenever possible. Variable `ess-use-ido'
          controls whether to use ido completion or not. Active by

        * ESS now supports comint fields for output and input
          detection. This feature is not used by default, but might be
          useful in the future.

        * ESS[S]: New custom variable `inferior-ess-S-prompt' to
          customize prompt detection regular expression in the inferior
          ESS buffers. You can customize this variable to enhance
          comint navigation (`comint-previous-prompt' and
          `comint-next-prompt') the inferior buffers.

        * ESS[R]: Internal `R' completion retrieval
          (`ess-R-complete-object-name')  was rewritten and is faster

        * ESS is using process plist to store process specific
          variables, as opposed to buffer local variables as it was
          using before. The use of buffer local variables to store
          process variables is discouraged.

        * ESS: new functions to manipulate process plists:
          `ess-process-get' and `ess-process-set'.

        * ESS: Internal process waiting mechanism was completely
          rewritten. ESS no more relies on prompt regular expressions
          for the prompt detection. The only requirement on the primary
          process prompt is to end in `> '. This could be overwritten
          by setting `inferor-ess-primary-prompt'.

        * ESS[S], notably `R': Saved command history:  ESS-HISTORY-FILE
          now accepts `t' (default), `nil', or a  file name. By setting
          it to `nil' no command line history is saved  anymore.
          ESS-HISTORY-DIRECTORY now allows to have the history  all
          saved in one "central" file.

        * ESS[R]: more Roxygen improvements.

        * ESS[R]: `C-c .' to set (indentation) style.

        * ESS[R]: Functions with non-standard names (for example
          'aaa-bbb:cc') are properly handled by font-lock and
          evaluation routines.

        * ESS[R]:Several regexp bugs (described in etc/R-ESS-bugs.el)
          were fixed in `ess-get-words-from-vector' and `ess-command'.
