+Changes from 0.8.1 to 0.8.1.1:
+
+ * Charts are now rendered with colours from the Tango palette instead
+ of fully saturated primaries.
+
+ * PSPP can now read and write ZCOMPRESSED system files, a new format
+ variant that compresses data much more effectively than the
+ previous form of compression (which is still supported).
+
+ * 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 is only capable of converting to comma-separated value
+ files..
+
+ * Build changes:
+
+ - zlib is now a required dependency. (Previously it was optional.)
