+Changes from 0.8.5 to 0.9.0:
+
+ * The QUICK CLUSTER command has a /PRINT subcommand which shows
+ the initial cluster centres and the final cluster membership of
+ each case. The clustering algorithm has also been updated, so
+ as to produce better separated clusters.
+
+ * A Russian localisation has been contributed.
+
+ * The graphic user interface now has a Graphs menu to access the GRAPH
+ command.
+
+ * The GRAPH command now has a /BAR subcommand to draw barcharts.
+
+ * The graphical user interface uses Gtk+ version 3 instead of version 2.
+ Accordingly, it has a somewhat different look and feel.
+
+ * The pspp-convert utility can now decrypt encrypted syntax files.
+ The encrypted syntax file format is unacceptably insecure, so to
+ discourage its use PSPP and PSPPIRE do not directly read or write
+ this format.
+
+ * Bug fixes, including the following notable ones:
+
+ - The correlation coefficient in the paired samples t-test
+ procedure is now correctly calculated when presented with
+ weighted data.
+
+ - The ESCAPE subcommand has been removed from GET DATA /TYPE=TXT.
+ For compatibility, the behavior that ESCAPE enabled is now the
+ default and only supported behavior.
