+ * 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.
+
+ Output changes:
+
+ * Output configuration options have changed. Please refer to the
+ manual for a full description of the available options.
+
+ In consequence, you will need to reinstall your "devices" file.
+ "make install" will do this for you.
+
+ * Most error messages are now written to PSPP output files by
+ default. SET ERROR can be used to disable this behavior.
+
+ * When invoked interactively, PSPP now by default produces output
+ on the terminal, piping it through the "more" program.
+ Previously, by default output was written only to file
+ pspp.list. On most terminals, the page length used for output
+ automatically adapts to the terminal size, even if the terminal
+ is resized.
+
+ * ASCII driver:
+
+ - This driver now supports charts in output. Charts are written
+ as separate files that the main output file refers to. By
+ default, charts are written in PNG format to files named
+ pspp-1.png, pspp-2.png, and so on.
+
+ - Configurations are provided that use VT100 (and xterm)
+ line-drawing characters in tables. The option "-o list-vt100"
+ requests use of this device for output to pspp.list.
+
+ * PostScript driver:
+
+ - The default paper size is now determined using the PAPERSIZE
+ environment variable, or the LC_PAPER locale category on
+ systems that support it. If these are not set, the default is
+ now A4, instead of US letter. To make US letter the default,
+ set PAPERSIZE to "letter" in your environment.
+
+ - Font metrics are now read from AFM files, instead of
+ Groff-format metrics files. PostScript fonts can now be
+ embedded in output.
+
+ In consequence, you will need to install an AFM file for each
+ font used in PostScript output. "make install" will install
+ AFM files for the standard PostScript fonts, including the
+ ones that the PostScript driver uses by default.
+
+ - Standard paper sizes no longer need to be specified through a
+ configuration file. The "papersize" configuration file is no
+ longer needed, or supported.
+
+ - The PostScript prologue is no longer obtained from the
+ "ps-prologue" configuration file. This configuration file is
+ no longer needed, or supported.
