-Changes from 0.10.2 to 0.10.4:
+Changes from 1.4.1 to 1.5.3:
+
+ * In the Kruskal-Wallis test, a misleading result could occur
+ if the lower bound specified by the user was in fact higher
+ than the upper bound specified. This has been fixed.
+
+ * The DEFINE, MATRIX, MCONVERT, and MATRIX DATA commands are now
+ implemented.
+
+ * An error in the displayed signficance of oneway anova
+ contrasts tests has been corrected.
+
+ * Added Drag-N-Drop in output view.
+
+ * The Explore GUI dialog supports the "Plots" subdialog. Boxplots, Q-Q Plots
+ and Spreadlevel plots are now also available via the GUI.
+
+ * The graphical user interface for importing spreadsheets has been improved.
+ The new interface provides the user with a preview of the data to be imported
+ and interactive methods to select the desired ranges.
+
+ * The user manual, in its Info and HTML versions, now includes
+ graphical output examples and screenshots.
+
+ * Build changes:
+
+ - Perl is no longer required to build.
+
+ - Build now requires Python 3.4 or later. (Building PSPP 1.4.0
+ also required Python, but it wasn't properly documented at the
+ time.)
+
+ - The Cairo and Pango libraries are now required.
+
+ - gettext 0.20 or later is now required.
+
+ * Output improvements:
+
+ - New drivers for output to TeX source files and to PNG files.
+
+ - Table output styles may now be set with the new option
+ --table-look and the new SET TLOOK command.
+
+ - New driver option "trim" to remove empty space from PDF,
+ PostScript, SVG, and PNG output files.
+
+ - The PDF output driver now adds an outline to allow PDF viewers to display
+ as a "table of contents" for the file.
+
+ - The HTML output driver has a new option "bare".
+
+ * New features in pspp-output:
+
+ - New --table-look and --nth-commands options.
+
+ - New get-table-look and convert-table-look commands.
+
+Changes from 1.4.0 to 1.4.1:
+
+ * Bug fixes.
+
+ * Translation updates.
+
+ * HTML output is now HTML5 instead of HTML4.0 Transitional.
+
+ * The HOST command has been reimplemented. It now supports TIMELIMIT.
+
+Changes from 1.2.0 to 1.4.0:
+
+ * The file pspp-mode.el (the pspp-mode for Emacs) is no longer distributed
+ with PSPP. Instead, it can be installed directly in emacs and is available
+ from https://elpa.gnu.org/packages/pspp-mode.html
+
+ * The Find dialog box, when searching for numeric values, will match only
+ to the precision of the variable's print format. This avoids behaviour
+ which is surprising to some users.
+
+ * 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 "--keep" and "--drop" options to output only selected variables.
+
+ - New "--recode", "--no-var-name", "--labels", "--print-formats",
+ "--decimal", "--delimiter", and "--qualifier" options to control
+ 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.
+
+ * 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.
+
+ * The Syntax Window now has a Find function to perform simple text
+ searching.
+
+ * AUTORECODE:
+
+ - The PRINT subcommand is now implemented.

+
+ * 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.
+
+Changes from 0.11.0 to 1.0.0:
+
+ * Translation updates.
+
+Changes from 0.10.2 to 0.11.0:
+
+ * The REGRESSION command now has a /ORIGIN subcommand to perform
+ regression through the origin.
+

* The MATRIX DATA command has been added.
* Some inappropriate properties in selection dialogs have been corrected.
