pspp-0.8.0 released [stable]

[Ben Pfaff]

I'm very pleased to announce the release of GNU PSPP 0.8.0.  We
hope to make releases more frequently in the future.

Here are the compressed sources and a GPG detached signature[*]:
  ftp://ftp.gnu.org/gnu/pspp/pspp-0.8.0.tar.gz
  ftp://ftp.gnu.org/gnu/pspp/pspp-0.8.0.tar.gz.sig

Use a mirror for higher download bandwidth:
  http://www.gnu.org/order/ftp.html

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify pspp-0.8.0.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver keys.gnupg.net --recv-keys C6648E90

and rerun the 'gpg --verify' command.

This release was bootstrapped with the following tools:
  Autoconf 2.69
  Automake 1.11.6
  Gnulib v0.0-7852-g408cb57

 * Changes to existing commands:

   - AUTORECODE has a new GROUP subcommand.

   - CROSSTABS has been re-implemented to fix numerous bugs.

   - EXAMINE: /MISSING=LISTWISE is now the default.

   - DO REPEAT command has been reimplemented.  Now, when DO REPEAT
     contains an INCLUDE or INSERT command, substitutions are not
     applied to the included file.
  
   - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.

   - HOST has been updated to use more modern syntax.

   - Most commands that work with data files now support a new
     ENCODING subcommand.

   - MISSING VALUES can now assign missing values to long string
     variables.

   - ONEWAY: the POSTHOC subcommand is now implemented.

   - The following new subcommands to NPAR TESTS have been implemented:
     COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, 
MANN-WHITNEY, 
     MCNEMAR, SIGN, WILCOXON, and RUNS

   - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
     DPROMPT subcommands.  The defaults are now fixed values.

   - SHOW now has a JOURNAL subcommand, to show the location of the
     journal file.

   - VALUE LABELS can now assign value labels to long string
     variables.

 * Other language changes:

   - The new DATASET commands replace the "scratch file" PSPP
     extension, which is no longer supported.

   - Strings may now include arbitrary Unicode code points specified
     in hexadecimal, using the syntax U'hhhh'.  For example, Unicode
     code point U+1D11E, the musical G clef character, may be
     expressed as U'1D11E'.

     See the "Tokens" section in the PSPP manual for more information.

   - In previous versions of PSPP, in a string expressed in
     hexadecimal with X'hh' syntax, the hexadecimal digits expressed
     bytes in the locale encoding.  In this version of PSPP, X'hh'
     syntax always expresses bytes in UTF-8 encoding.

     See the "Tokens" section in the PSPP manual for more information.

 * PSPPIRE graphical user interface improvements:

   - Added support for non-ASCII characters in strings, labels and
     variable names.

   - A "Split Window" function is available, which makes it easier to
     see different parts of a large data file.

   - Data files can now be opened by specifing their name as the first
     argument.  This means that on a properly configured desktop, double
     clicking on an icon will open the file.

   - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
     via using an "intelligent" application assistant dialog.

 * Output changes:

   - The new "cairo" output driver supports output in PostScript, PDF,
     and SVG formats.  Its functionality is a superset of that of the
     "postscript" driver, which has been removed.  You must have Cairo
     and Pango installed to build the "cairo" driver.

   - Charts are now produced with Cairo and Pango, instead of libplot.
     Without them, the new graphing features will not work.  If you do
     not have Cairo and Pango installed, you must run `configure' with
     --without-cairo.

   - The plain text output driver now properly supports multibyte UTF-8
     characters, including double-width characters and combining
     accents.

   - Output to OpenDocument format is now supported.

   - The HTML output is much improved.

 * The "pspp" program has a new option --batch (or -b) that selects
   "batch" syntax mode.  In previous versions of PSPP this syntax mode
   was the default.  Now a new "auto" syntax mode is the default.  In
   "auto" mode, PSPP interprets most syntax files correctly regardless
   of their intended syntax mode.

   See the "Syntax Variants" section in the PSPP manual for more
   information.

 * The "pspp" program has a new option --syntax-encoding that
   specifies the encoding for syntax files listed on the command line,
   as well as the default encoding for syntax files included with
   INCLUDE or INSERT.  The default is to accept the system locale
   encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
   one the system file uses.

   See the documentation for the INSERT command in the PSPP manual for
   more information.

 * Text data files that PRINT and WRITE creates now use the system
   native line ends by default (CRLF on Windows, LF only elsewhere).
   Use the new ENDS subcommand on FILE HANDLE to override the default.

 * A new Perl module allows Perl programs to read and write PSPP
   system files.

 * A tutorial chapter has been added to the user manual.
