+ * 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.
+
+Changes from 0.3.0 to 0.4.0:
+
+ Changes in build dependencies:
+
+ * The GNU Scientific Library (libgsl), version 1.6 or later, is
+ now required.
