-Changes since 0.8.2:
+Changes from 0.8.5 to 0.9.0:
+
+ * 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.
+
+ * 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 occured
+ 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.
+
+ * Bug fixes, including the following notable ones:
+
+ - FREQUENCIES works properly for string variables. (This bug was
+ introduced in 0.8.2.)
+
+ - CROSSTABS now correctly computes all of the measures that it
+ offers. Some measures have been removed because they were not
+ computed correctly.
+
+ - The NPAR TESTS calculation of significance for the RUNS
+ subcommand has been corrected.
+
+ - 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.
+
+Changes from 0.8.2 to 0.8.3:
+
+ * Independent T-Tests displayed the standard error of the difference
+ and the confidence interval for the unequal variances case, where
+ the equal variances case should have been. This has been fixed.
* REGRESSION now recognises /STATISTICS=CI(x) which causes confidence
intervals for the coefficients to be printed.
+ * When DESCRIPTIVES calculates Z scores, it now omits cases filtered
+ by the current FILTER settings.
+
* PSPPIRE graphical user interface improvements:
+ - Dialog boxes with source variable lists can now choose the sort
+ order; right click and select from the popup menu.
+
- File|Open now allows an encoding to be selected for opening
system files.
- SYSFILE INFO now accepts an ENCODING subcommand to specify the
character encoding of string data in the system file.
+ - Variable labels over 255 bytes long are now accepted without
+ truncation (bug #41863).
+
- System files that contain duplicate variable names may now be
read successfully (bug #41475).
