+Changes from 1.2.0 to 1.3.0:
+
+ * PSPP now supports the SPSS viewer (.spv) format that SPSS 16 and later
+ use to save the contents of its output editor:
+
+ - PSPP and PSPPIRE can write output to .spv files.
+
+ - The new utility pspp-output can convert .spv files to other formats.
+
+ - The pspp-convert utility can now decrypt encrypted .spv files. The
+ encrypted viewer file format is unacceptably insecure, so to
+ discourage its use PSPP and PSPPIRE do not directly read or write
+ this format.
+
+ * A bug where the Data|Select Cases|Random Sample menu would generate
+ invalid syntax has been fixed.
+
+ * FREQUENCIES will emit a warning if one or more weight values are missing.
+
+ * Plain text output is no longer divided into pages, since it is now
+ rarely printed on paper.
+
+ * pspp-convert improvements:
+
+ - New "-a", "-l", "--password-list" options to search for an
+ encrypted file's password.
+
+ - New "--labels" and "--recode" options for CSV output.
+
+ * Improvements to SAVE DATA COLLECTION support for MDD files.
+
+ * Bug fix for CVE-2018-20230.
+
+ * The /RENAME subcommand in SAVE TRANSLATE et al. has been extended
+ to support the syntax also accepted by other software.
+
+ * The EXAMINE command will now perform the Shapiro-Wilk test when
+ one or more plots are requested.
+
+ * The REGRESSION command now supports the /STATISTICS=TOL option which
+ outputs tolerance and variance inflation factor metrics for the data.
+
+ * The QUICK CLUSTER command now supports the /SAVE option which can
+ be used to save the cases' cluster membership and/or their distance
+ from the cluster centre to the active file.
+
+ * The MEANS command has been re-implemented.
+
+ * A bug where the GUI would crash when T-TEST was executed whilst
+ a filter was set has been fixed.
+
+ * The GUI now has a sub-dialog for post-hoc tests of the oneway
+ anova test.
+
+ * Gtk+3.22.0 or later must now be used when building.
+
+ * GRAPH: Categorical barcharts displaying percentages now show the
+ sub-category as a percentage of the primary category instead of the
+ total.
+
+ * AUTORECODE:
+
+ - The PRINT subcommand is now implemented.
+
+ - Many bug fixes.
+
+Changes from 1.0.1 to 1.2.0:
+
+ * New experimental command SAVE DATA COLLECTION to save MDD files.
+
+ * MTIME and YMDHMS variable formats now supported.
+
+ * Build changes:
+
+ - zlib is now a required dependency. (Previously it was optional.)
+
+ - Gtk+3.18.0 or later must now be used when building.
+
+ - The code implementing the sheet rendering has been removed. Instead we
+ use a third party library: spread-sheet-widget.
+
+ * The "NOMISSING" keyword when generating syntax for piecharts in the
+ frequencies command was omitted. This has been corrected.
+
+Changes from 1.0.0 to 1.0.1:
+
+ * Bug fixes, including fixes for CVE-2017-12958, CVE-2017-12959,
+ CVE-2017-12960, and CVE-2017-12961.
