pspp-2.0.0 released [stable]

[Ben Pfaff]

I'm very pleased to announce the release of a new version of GNU PSPP.
PSPP is a program for statistical analysis of sampled data.  It is a
free replacement for the proprietary program SPSS.

Here are the compressed sources and a GPG detached signature[*]:
  https://ftp.gnu.org/gnu/pspp/pspp-2.0.0.tar.gz
  https://ftp.gnu.org/gnu/pspp/pspp-2.0.0.tar.gz.sig

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

The GNU project does not release official PSPP binaries.  For links to
locations where third parties offer binaries, please visit:
  http://www.gnu.org/software/pspp/get.html
It might take hours or days before binaries for a new release become
available.

[*] 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-2.0.0.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 
C2D1AB061656AAC54B5E975485199DE8C6648E90

or obtain the project members' keys directly from Savannah:

  wget -q -O- 
'https://savannah.gnu.org/project/memberlist-gpgkeys.php?group=pspp&download=1' 
| gpg --import -

Either way, afterward, rerun the 'gpg --verify' command.

Changes from 1.6.2-pre2 to 2.0.0:

 * The CTABLES command is now implemented.

 * FREQUENCIES now honors the LAYERED setting on SPLIT FILE.

 * AGGREGATE:

   - New aggregation functions CGT, CLT, CIN, and COUT.

   - Break variables are now optional.

 * ADD FILES, MATCH FILES, and UPDATE now allow string variables with
   the same name to have different widths.

 * CROSSTABS now calculates significance of Pearson and Spearman
   correlations in symmetric measures.

 * DISPLAY MACROS is now implemented.

 * SET SUMMARY is now implemented.

 * SHOW ENVIRONMENT is now implemented.

 * Removed the MODIFY VARS command, which is not in SPSS.

 * Building from a Git repository, which previously required GIMP, now
   requires rsvg-convert from librsvg2 instead.

 * The pspp-dump-sav program is no longer installed by default.

 * Improved the search options in the syntax editor.

 * Localisations for the ar (Arabic) and ta (Tamil) locales have been
   added.  Other translations have been updated.

 * Journaling is now enabled by default when PSPP or PSPPIRE is
   started interactively.  In PSPPIRE, use Edit|Options to override
   the default.
