+ - 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.
+
+ * HTML driver:
+
+ - The HTML prologue is no longer obtained from the
+ "html-prologue" configuration file. This configuration file
+ is no longer needed, or supported.
+
+ Command language changes:
+
+ * The following commands are new:
+
+ - GET DATA, which currently supports reading Gnumeric files and
+ text data files. It will be extended later to read other
+ types of foreign data.
+
+ - CD, to change the current directory.
+
+ - INSERT, to execute a syntax file.
+
+ - DELETE VARIABLES, to remove variables from the active file
+ dictionary.
+
+ - ADD DOCUMENT, to add text to active file documents.
+
+ - CLOSE FILE HANDLE (a PSPP extension; see below).
+
+ - XEXPORT, a PSPP extension that is a transformation equivalent
+ to EXPORT.
+
+ * The following functions for transformation expressions are new:
+
+ - DATEDIFF, for computing the difference of two dates.
+
+ - DATESUM, for advancing a date by a specified duration.
+
+ - VALUELABEL, to obtain the value label for a value.
+
+ * PSPP now supports very long string variables (over 255 bytes
+ long).
+
+ * MATCH FILES now supports the FIRST and LAST subcommands.
+
+ * Previous versions of PSPP prohibited using commands to both read and
+ write a single file at the same time. Now, PSPP allows this, and
+ the new version of the file atomically replaces the old version.
+
+ * The following commands are no longer available. They will be
+ re-implemented in a later release:
+
+ - CLEAR TRANSFORMATIONS
+
+ - MATRIX DATA
+
+ - REPEATING DATA
+
+ * The PROCESS IF command, which was deprecated, has been removed.
+ You may replace any usage of it by SELECT IF following
+ TEMPORARY, which has the same effect.
+
+ * The output format for variables created by VECTOR may now be
+ specified as part of the VECTOR syntax.
