+Changes from 0.4.0 to 0.4.3:
+
+ * 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.
+
+ * Journaling of interactive commands to a disk file is now
+ implemented. By default, journaling is enabled, to a file named
+ `pspp.jnl' in the current directory. SET JOURNAL may be used to
+ control journaling.
+
+ * The use of `+' between syntax file names on the command line to
+ prevent the dictionary from being cleared between their
+ executions is no longer supported. All syntax files are now
+ executed as if `+' had been specified.
+
+ * The -d/--define and -u/--undef command line options are no
+ longer supported. Instead, use /usr/bin/env or shell primitives
+ to define or clear environment variables before invoking PSPP.
+
+ * If a syntax file named named `rc' is found in a configuration
+ directory (such as $HOME/.pspp), it is executed before any
+ syntax file specified on the command line. The -r or
+ --no-statrc command line option may be used to disable this
+ behavior.
