See the end for copying conditions. Please send PSPP bug reports to bug-gnu-pspp@gnu.org. -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. - File|Display Data File Information|External File... now allows an encoding to be selected. + - A problem with the Means dialog has been resolved (bug #41433). + + - Several problems related to the input of spreadsheets have been + fixed (bug #41657, #41620 + * System file related improvements: - With ENCODING="DETECT", SYSFILE INFO can now help the user to @@ -26,6 +144,9 @@ Changes since 0.8.2: - 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).
