+Changes from 0.8.1 to 0.8.1.1:
 
-Changes after 0.8.0:
+ * 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.
+
+   (Earlier versions of PSPP that supported missing values for long
+   string variables wrote them to system files in an SPSS-incompatible
+   way.  To fix the problem, read the system file with this version of
+   PSPP and then save a new copy of it.)
+
+ * pspp-convert, a new standalone utility for converting SPSS system
+   and portable files to other formats, is now included.  The initial
+   version supports comma-separated value files as output format.
+   pspp-convert can also decrypt encrypted system files.
+
+ * Build changes:
+
+   - zlib is now a required dependency.  (Previously it was optional.)
+
+Changes from 0.8.0 to 0.8.1:
 
  * New commands:
 
    - VARIABLE ROLE.
 
+ * Changes to existing commands:
+
+   - CROSSTABS: The requirement that one expected count must be less than five
+       before Fishers Exact Test will be reported has been removed.
+
  * PSPPIRE graphical user interface improvements:
 
    - A new set of icons has been contributed.
