As pre-announced (Fri, 18 Sep 2015 13:11:16 +0200),
ESS 15.09 (2015 - September) has been released now.
To get it, use http://ess.r-project.org/index.php?Section=download
The biggest changes are in indentation behavior which has become
much more consistent and still more flexible, notably thanks to
our new team member Lionel Henry (thank you, Lionel!)
Other improvements concern the julia interface, where now use
and build on julia-mode.el from the Julia project. The many
changes of julia however have also invalidated some features of
the ESS interface which will be addressed later.
Several other improvements / bug fixes have been incorporated since
the spring release 15.03. See below for the current documented
list of new features for 15.09.

1 ANNOUNCING ESS
****************
The ESS Developers proudly announce the release of ESS 15.09
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
(currently, specifically, the 23.x and 24.x series;
alpha/beta/pre-release versions are NOT SUPPORTED). Non-Windows users
beware: GNU Emacs 24.3 is preferable to 24.1 or 24.2: these broken
builds suffer from bug 12463
<http://debbugs.gnu.org/cgi/bugreport.cgi?bug=12463> which will cause
emacs and ESS to get progressively slower over time.
Due to XEmacs lacking some features that ESS requires, ESS support of
XEmacs ends with ESS 12.04-4. This decision will be re-visited in the
future as XEmacs continues to sync with GNU Emacs.
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 using stat.math.ethz.ch>;
contributions to the list may be mailed to <ess-help using 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 using 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 and New Features in 15.09:
* ESS[R]: The indentation logic has been refactored. It should be
faster, more consistent and more flexible. There are three types
of indentation settings, those starting with 'ess-offset-' give the
actual offsets, those starting with 'ess-indent-' are control
(commonly Boolean) variables, and those starting with 'ess-align-'
are vertical alignment overrides which inhibit default offsets in
specific situations. See 'ess-style-alist' for detailed
description of the new indentation system and provided default
indentation styles.
* ESS[R]: Deprecation of old indentation settings. As a consequence
of the indentation re-factoring 'ess-brace-imaginary-offset',
'ess-expression-offset' and all delimiter-specific offsets are
deprecated. The settings for indentation of continued statements
have been replaced by 'ess-offset-continuations'. It can be set to
either 'cascade' or 'straight' (the default).
'ess-arg-function-offset' has been replaced by
'ess-indent-from-lhs' and has been generalised to assignements.
This setting now works with both statement blocks and expressions
and only takes effect for offsets set to 'prev-call' and
'open-delim' in order to produce a consistent indentation.
* ESS: A test framework has been set up.
* ESS[R]: A new RStudio style is provided to mimic as closely as
possible R files indented via RStudio. To reproduce the setup of
some of the RStudio users, the RStudio- style with
'ess-offset-arguments' set to 'prev-line' is also provided. In
addition, the new RRR+ style is equivalent to RRR except it indents
blocks in function calls relatively to the opening delimiter. This
style does not try to save horizontal space and produces more
indentation.
* ESS[R]: Roxygen fields will now be indented on paragraph refilling
in order to make the documentation more readable. You can also
refill commented lines in the 'examples' field without squashing
the surrounding code in the comments.
* ESS[R]: ESS can now format your code! This is controlled through
the settings 'ess-fill-calls' and 'ess-fill-continuations'. When
activated, '(fill-paragraph)' formats your calls and your
formulas/continuations while making sure they don't go past
'fill-column'. Repeated refills cycle through different styles
(see the docstrings for more details). By default, the refilled
region blinks. Set 'ess-blink-filling' to nil to prevent this.
* ESS[R]: Fix occasional missing error location fontification in
inferior buffers.
* ESS[R]: ess-developer now correctly assigned the environment of new
functions to the package namespace.
* ESS[Julia]: ?[topic] now works in the *julia* buffer. Note that
support for editing Julia code now depends on 'julia-mode.el' from
the Julia project. If you install ESS from the official
tarball/zip file, 'julia-mode.el' is already included. Otherwise,
if you install ESS by running 'make', then the latest version of
'julia-mode.el' is downloaded (and so you need an active internet
connection to install) during the installation process.
Alternatively, if you run ESS without running 'make', then ensure
that you have the 'julia-mode.el', which you can get easily from
MELPA for example.
* iESS: For naming inferior processes, ESS can use 'projectile''s
project root and it does so when
'ess-gen-proc-buffer-name-function' is set to
'ess-gen-proc-buffer-name:projectile-or-simple' as by default, or
to another value beginning with
'ess-gen-proc-buffer-name:projectile-*'.
