 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
  
+Changes since 0.8.5:
+
+ * The graphical user interface uses Gtk+ version 3 instead of version 2.
+   Accordingly, it has a somewhat different look and feel.
+
+ * 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.
+
 Changes from 0.8.4 to 0.8.5:
 
  * The FREQUENCIES and CROSSTABS commands can now generate barcharts.
