  * Charts are now rendered with colours from the Tango palette instead
    of fully saturated primaries.
 
+ * Support for new system file variants:
+
+   - PSPP can now read and write ZCOMPRESSED system files, which
+     compress data much more effectively than older "compressed"
+     files.  (The older format is still supported.)
+
+   - PSPP can now decrypt encrypted system files, using the new
+     pspp-convert utility.  The encrypted system file format is
+     unacceptably insecure, so to discourage its use PSPP and PSPPIRE
+     do not directly read or write this format.
+
  * Missing values for long string variables are now read from and
    written to system files in an SPSS-compatible fashion.
