+Changes from 0.3.0 to 0.4.0:
+
+ New build dependencies:
+
+ * The GNU Scientific Library (libgsl), version 1.6 or later.
+
+ * The GNU multiprecision arithmetic library (libgmp).
+
+ * libplot from GNU plotutils is optional. Without it, the new
+ graphing features will not work. If you do not have it
+ installed, you must run `configure' with --without-libplot.
+
+ Newly implemented commands and statistical features:
+
+ * EXAMINE, including its graphing features.
+
+ * FREQUENCIES now supports percentiles.
+
+ * ONEWAY.
+
+ * PERMISSIONS.
+
+ * SHOW.
+
+ * SORT CASES now sorts stably, that is, two cases with equal sort
+ criteria will be in the same relative order before and after the
+ sort.
+
+ * T-TEST (re-written).
+
+ * DATE and USE. These commands are parsed but otherwise ignored,
+ to enhance compatibility with certain command files that invoke
+ them unnecessarily.
+
+ * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
+ currently have no effect on PSPP output, but their values are
+ written to and read from system files and thus may affect
+ third-party software.
+
+ * SET EPOCH implemented.
+
+ * DATA LIST FREE and DATA LIST LIST now support arbitrary field
+ delimiters.
+
+ * FILE HANDLE now supports custom tab widths.
+
+ Long variable names (and other identifiers) are now supported. Up
+ to the first 64 bytes of each identifier is significant. PSPP now
+ reads and writes system files compatible with SPSS version 12.
+
+ New --algorithm and --syntax command line options allow
+ SPSS-compatible or enhanced modes to be selected.
+
+ Support for transformation expressions has been rewritten and
+ significantly improved. Refer to the manual for details.
+
+ Calculation of moments (mean, standard deviation, kurtosis,
+ skewness) has been rewritten and should now be more accurate. In
+ --algorithm=enhanced mode moments may be more accurate than SPSS in
+ some cases.
+
+ Numerous bugs have been fixed, too many to mention here. Many new
+ tests have been added, leading to the discovery and fixing of many
+ of these bugs.
+
+ The ASCII output driver can now squeeze multiple blank lines into
+ single blank lines.
+
+ Much of the code has been rewritten and refactored. It is now much
+ cleaner.
+
+ The FILE TYPE and REPEATING DATA commands have been disabled for
+ this release because their implementations were deemed too buggy to
+ be useful. They will be fixed and replaced in a future release.
+
+ New pspp-mode for Emacs (in pspp-mode.el).
+
+ Added rudimentary command-line completion for interactive input.
+
+ lib/julcal and lib/dcdflib are no longer used, so they have been
+ removed.
+
+ For developers, the build system now requires Autoconf 2.58 and
+ Automake 1.7. The included gettext has been updated to version
+ 0.12.1.
