 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
+
+Changes since 0.4.2:
+
+  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.
 \f
+Changes since 0.4.0 to 0.4.1:
+
+  Added support for very long string variables > 255 bytes.
+
+  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.
+
+    * The PostScript driver now obtains font metrics from AFM files,
+      instead of Groff-format metrics files.  It can now embed
+      PostScript fonts in its 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 files, including the ones that
+      the PostScript driver uses by default.
+
+  Newly implemented commands and statistical features:
+
+    * CLOSE FILE HANDLE (a PSPP extension; see below).
+
+    * REGRESSION.
+
+    * XEXPORT (a PSPP extension).
+
+  New PSPP extension:
+
+    A new PSPP extension called "scratch files" has been implemented.
+    A scratch file, like a system file, consists of a dictionary and
+    any number of cases.  Small scratch files are stored in memory;
+    one that grows too large is written to disk.  By default, any file
+    handle whose name begins with # is assumed to refer to a scratch
+    file.
+
+    Scratch files can be used just about anywhere a system or portable
+    file can be used.  Also, portable files are now allowed in most
+    places that system files were allowed in previous PSPP version.
+
+    A new CLOSE FILE HANDLE command allows the storage associated with
+    scratch files to be freed.  It also allows file handles to be
+    reassigned to new files.
+
+    For more information on scratch files, refer to the "File Handles"
+    section in the PSPP manual.  For specifics of what commands now
+    allow what kinds of files to be specified, refer to the
+    documentation on those particular commands.
+
+  PSPP is now able to start up and run even if it cannot find its
+  configuration files.
