+ * Updated Perl module interface.
+
+ * Value labels for long string variables are now supported.
+
+ * Missing values for long string variables are now supported.
+
+Changes from 0.7.0 to 0.7.1:
+
+ * Added a perl module to facilitate reading and writing of pspp system
+ files from perl programs.
+
+Changes from 0.6.1 to 0.7.0:
+
+ * Custom variable and data file attributes are now supported.
+ Commands VARIABLE ATTRIBUTE and DATAFILE ATTRIBUTE have been added
+ for setting and clear attributes. Support for attributes has also
+ been added to commands that read and write system files, such as
+ SAVE and GET, as well as to the DISPLAY command.
+
+Changes from 0.6.0 to 0.6.1:
+
+ * Statistical bug fixes:
+
+ - Report correct standardized regression coefficients in linear
+ regression output (bug #23567).
+
+ * Bug fixes that affect PSPP and PSPPIRE:
+
+ - Avoid crash with pie charts (bug #24014).
+
+ - Don't append % to count totals (bug #24003).
+
+ - Don't crash on bad input (bug #24031).
+
+ - Don't crash if "end data." is not left aligned (bug #24115).
+
+ - Change default workspace value to 64 MB, to avoid unnecessary
+ disk accesses on modern machines.
+
+ * PSPPIRE bug fixes:
+
+ - Add ".sav" or ".por" suffix to filename when saving with Save_As
+ (bug #23137).
+
+ - Make it possible to reopen the output window on Windows (bug
+ #24033).
+
+ - A POSIX regular expression library is now included and used
+ automatically if the host does not have one or has one that is
+ inadequate.
+
+ * Build fixes and changes:
+
+ - Work around bug in GSL that prevented build with recent GCC
+ versions without manually adding -fgnu89-inline to CFLAGS.
+
+ - Also warn about missing prerequisites as we encounter them (bug
+ #24445).
+
+ - Distribute necessary files to allow users working from the
+ distributed tarball to configure with --enable-gui-tools.
+
+ - Append $(EXEEXT_FOR_BUILD) to output file name when building
+ q2c, fixing build problems on Windows.
+
+ - GSL 1.8 or later is now required.
+
+ - Build errors with --enable-relocatable were fixed.
+
+ * The German translations were removed, since native German speakers
+ found them too poor to be useful.
+
+Changes from 0.4.0 to 0.6.0:
+
+ * The PSPP license is now version 3 or later of the GNU General
+ Public License. Previously, it was version 2 or later.
+
+ * PSPP now has a graphical interface, called PSPPIRE. This
+ interface allows you to enter data and variable definitions
+ interactively. Commands may be executed in syntax form, or by
+ using the interactive dialog boxes available from the dropdown
+ menus.
+
+ * A few sample syntax files are now included in the `examples'
+ directory.
+
+ * Numerous major and minor bugs have been fixed.
+
+ Build changes:
+
+ * The INSTALL file now reflects the details of how to install
+ PSPP. It is a tailored version of the generic installation
+ instructions, instead of a verbatim copy.
+
+ * iconv, which is ordinarily installed as part of a Unix-like
+ system, is now required. If you don't have it already, you can
+ install GNU libiconv (http://www.gnu.org/software/libiconv/).
+
+ * libxml2 and zlib are new optional dependencies. They are
+ required to use PSPP's support for reading Gnumeric files.
+
+ Statistical procedure changes:
+
+ * REGRESSION is a new procedure for fitting linear models to data
+ via least-squares estimation.
+
+ * NPAR TESTS is a new procedure for non-parametric tests. In this
+ release, it supports binomial and chi-square tests.
+
+ * RANK is a new procedure to rank variables. It supports numerous
+ forms of ranking.
+
+ * FREQUENCIES can now output histograms and pie charts. These
+ features were present in earlier releases, but not documented.
+
+ User interface changes:
+
+ * In many situations where PSPP once terminated with a fatal
+ error, PSPP now recovers and continues execution.
+
+ * PSPP is now able to start up and run even if it cannot find its
+ configuration files.
