-Changes since 0.8.4:
- * FREQUENCIES: A bug was fixed where an assertion failure occured
+Changes since 1.2.0:
+
+ * Plain text output is no longer divided into pages, since it is now
+ rarely printed on paper.
+
+ * pspp-convert: New "-a", "-l", "--password-list" options to search
+ for an encrypted file's password.
+
+ * Improvements to SAVE DATA COLLECTION support for MDD files.
+
+ * Bug fix for CVE-2018-20230.
+
+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.
+
+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 FACTOR command can now analyse matrix files prepared with MATRIX DATA.
+
+ * The FACTOR command can now print the anti-image matrices.
+
+ * The MATRIX DATA command has been added.
+
+ * Some inappropriate properties in selection dialogs have been corrected.
+
+ * A bug which could cause the HTML driver to go into a tight loop
+ has been fixed.
+
+ * An error in the FREQUENCIES procedure, where the word "Mean" was
+ printed when "Variance" was appropriate has been fixed.
+
+ * The ncurses library is no longer required or used.
+
+ * A bug where the Mann-Whitney test would give misleading results
+ if run on multiple variables and MISSING=ANALAYSIS was specified
+ has been fixed.
+
+ * Gtk+3.14.5 or later must now be used when building.
+
+ * Graphical user interface changes:
+
+ ** There is a new menu: Edit|Options
+
+ ** The Non Parametric Statistics Menu has a new item: "K Independent Samples".
+
+ ** Dialog boxes can now be canceled using the <Escape> key.
+
+ * The AUTORECODE command now accepts an optional / before INTO.
+
+ * The short form of the VECTOR command can now create string variables.
+
+ * Bug fixes, including fixes for CVE-2017-10791 and CVE-2017-10792.
+
+Changes from 0.10.1 to 0.10.2:
+
+ * CROSSTABS implements a new COUNT subcommand to round case or cell
+ weights.
+
+ * Help will be opened as HTML in default browser if yelp
+ is not available.
+
+ * When plotting scatterplots with only one dataset (the simple case)
+ the colour used for the dataset is now black. The previous default
+ from the Tango palette was too faint to see easily.
+
+ * The varible info dialog could previously only paste a single variable.
+ Now it can paste multiple variables.
+
+ * Bug fixes, including the following:
+
+ - T-test with independent samples GUI crashed with string
+ type variable as group variable.
+
+ - The variable info dialog showed the previous selected variable
+ superimposed with the currently selected one.
+
+ - The GLM command did not properly deal with missing values. This
+ has been fixed.
+
+Changes from 0.10.0 to 0.10.1:
+
+ * Bug fixes, including the following:
+
+ - A bug where certain dialog boxes could not be properly populated
+ has been fixed.
+
+ - Various commands have been hardened against errors when called
+ with invalid syntax.
+
+ * Translation updates. Thanks to our translators!
+
+Changes from 0.8.5 to 0.10.0:
+
+ * The QUICK CLUSTER command has a /PRINT subcommand which shows
+ the initial cluster centres and the final cluster membership of
+ each case. The clustering algorithm has also been updated, so
+ as to produce better separated clusters.
+
+ * A Russian localisation has been contributed.
+
+ * The GRAPH command now has a /BAR subcommand to draw barcharts.
+
+ * If the DECIMAL character is set to COMMA then the ',' character
+ will not be treated as a separator by DATA LIST.
+
+ * The graphical user interface (psppire) has been changed as follows:
+
+ - It now uses Gtk+ version 3 instead of version 2. Accordingly, it has a
+ somewhat different look and feel.
+
+ - There is now a Graphs menu to access the GRAPH command.
+
+ - The status of dialog box widgets are now preserved between calls
+ to the same dialog box for the same dataset.
+
+ - The dialog box for the Logistic Regression command will now
+ infer that string variables or any varible with a "measure"
+ of Nominal or Ordinal are to be treated as categorical variables
+ and will generate syntax accordingly.
+
+ * The pspp-convert utility can now decrypt encrypted syntax files.
+ The encrypted syntax file format is unacceptably insecure, so to
+ discourage its use PSPP and PSPPIRE do not directly read or write
+ this format.
+
+ * New commands:
+
+ - SORT VARIABLES.
+
+ * The following functions for transformation expressions are new:
+
+ - REPLACE, for search-and-replace of one string with another.
+
+ - STRUNC, to truncate a string and trim trailing spaces.
+
+ - MEDIAN, to compute the median of its arguments.
+
+ - The TRUNC function in expressions now supports additional arguments
+ for truncating to values other than integers and to indicate a level
+ of rounding fuzz. The default rounding fuzz may now be controlled
+ and displayed with SET FUZZBITS and SHOW FUZZBITS, respectively.
+
+ * Bug fixes, including the following notable ones:
+
+ - The correlation coefficient in the paired samples t-test
+ procedure is now correctly calculated when presented with
+ weighted data.
+
+ - The ESCAPE subcommand has been removed from GET DATA /TYPE=TXT.
+ For compatibility, the behavior that ESCAPE enabled is now the
+ default and only supported behavior.
+
+ - Rendering of the variable and data sheets in right-to-left locales
+ now works properly.
+
+ - The Mann-Whitney test, when run on a dataset containing values
+ of the group variable, other than those defining the test groups,
+ would incorrectly calculate the ranks. This has been corrected.
+
+ * The IMPORTCASES subcommand on GET DATA is now ignored, for
+ compatibility.
+
+Changes from 0.8.4 to 0.8.5:
+
+ * The FREQUENCIES and CROSSTABS commands can now generate barcharts.
+
+ * The FACTOR command can now perform PROMAX rotations.
+
+ * SPSS/PC+ system files are now supported on GET and other commands
+ that read SPSS system files. The pspp-convert program can now read
+ SPSS/PC+ system files. Writing the obsolete SPSS/PC+ system file
+ format is not supported.
+
+ * SYSFILE INFO can now read SPSS/PC+ system files and SPSS portable
+ files.
+
+ * FREQUENCIES: A bug was fixed where an assertion failure occurred
when an empty dataset was presented.
* The GRAPH command is now available. Initially it supports
scatterplots and histograms.
+ * The RND operator in expressions now supports additional operands
+ for rounding to values other than integers and to indicate a level
+ of rounding fuzz. The default rounding fuzz may now be controlled
+ and displayed with SET FUZZBITS and SHOW FUZZBITS, respectively.
+
Changes from 0.8.3 to 0.8.4:
* Formatting of SYSFILE INFO output was made easier to read.
- Planned comparisons in ONEWAY ANOVA now correctly handle negative
T-values.
+ - The COUNT command now correctly treats missing values as
+ documented.
+
- Conformance fixes to Open Document output format.
