pspp-1.4.0 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-1.4.0.tar.gz
  https://ftp.gnu.org/gnu/pspp/pspp-1.4.0.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-1.4.0.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 85199DE8C6648E90

and rerun the 'gpg --verify' command.

Changes from 1.2.0 to 1.4.0:

 * The file pspp-mode.el (the pspp-mode for Emacs) is no longer distributed
   with PSPP.  Instead, it can be installed directly in emacs and is available
   from https://elpa.gnu.org/packages/pspp-mode.html

 * The Find dialog box, when searching for numeric values, will match only
   to the precision of the variable's print format.  This avoids behaviour
   which is suprising to some users.

 * PSPP now supports the SPSS viewer (.spv) format that SPSS 16 and later
   use to save the contents of its output editor:

   - PSPP and PSPPIRE can write output to .spv files.

   - The new utility pspp-output can convert .spv files to other formats.

   - The pspp-convert utility can now decrypt encrypted .spv files.  The
     encrypted viewer file format is unacceptably insecure, so to
     discourage its use PSPP and PSPPIRE do not directly read or write
     this format.

 * A bug where the Data|Select Cases|Random Sample menu would generate
   invalid syntax has been fixed.

 * FREQUENCIES will emit a warning if one or more weight values are missing.

 * Plain text output is no longer divided into pages, since it is now
   rarely printed on paper.

 * pspp-convert improvements:

   - New "-a", "-l", "--password-list" options to search for an
     encrypted file's password.

   - New "--keep" and "--drop" options to output only selected variables.

   - New "--recode", "--no-var-name", "--labels", "--print-formats",
     "--decimal", "--delimiter", and "--qualifier" options to control
     CSV output.

 * Improvements to SAVE DATA COLLECTION support for MDD files.

 * Bug fix for CVE-2018-20230.

 * The /RENAME subcommand in SAVE TRANSLATE et al. has been extended
   to support the syntax also accepted by other software.

 * The EXAMINE command will now perform the Shapiro-Wilk test when
   one or more plots are requested.

 * The REGRESSION command now supports the /STATISTICS=TOL option which
   outputs tolerance and variance inflation factor metrics for the data.

 * The QUICK CLUSTER command now supports the /SAVE option which can
   be used to save the cases' cluster membership and/or their distance
   from the cluster centre to the active file.

 * The MEANS command has been re-implemented.

 * The GUI now has a sub-dialog for post-hoc tests of the oneway
   anova test.

 * Gtk+3.22.0 or later must now be used when building.

 * GRAPH: Categorical barcharts displaying percentages now show the
   sub-category as a percentage of the primary category instead of the
   total.

 * The Syntax Window now has a Find function to perform simple text
   searching.

 * AUTORECODE:

   - The PRINT subcommand is now implemented.

   - Many bug fixes.
