5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
13 * PSPPIRE graphical user interface improvements:
15 - A new set of icons has been contributed.
17 - Syntax windows now parse syntax in "auto" mode, which in practice
18 should mean that both "batch" and "interactive" syntax now works,
19 instead of just "interactive" syntax.
21 - The variable pane of data windows now include a Role column.
25 - System files written by IBM SPSS 21 are now read without warnings.
27 - PSPPIRE should now more gracefully handle syntax files that contain
30 Changes from 0.6.2 to 0.8.0:
47 - PRESERVE and RESTORE
51 - SAVE TRANSLATE to CSV and tab-delimited files
55 * Changes to existing commands:
57 - AUTORECODE has a new GROUP subcommand.
59 - CROSSTABS has been re-implemented to fix numerous bugs.
61 - EXAMINE: /MISSING=LISTWISE is now the default.
63 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
64 contains an INCLUDE or INSERT command, substitutions are not
65 applied to the included file.
67 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
69 - HOST has been updated to use more modern syntax.
71 - Most commands that work with data files now support a new
74 - MISSING VALUES can now assign missing values to long string
77 - ONEWAY: the POSTHOC subcommand is now implemented.
79 - The following new subcommands to NPAR TESTS have been implemented:
80 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
81 MCNEMAR, SIGN, WILCOXON, and RUNS
83 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
84 DPROMPT subcommands. The defaults are now fixed values.
86 - SHOW now has a JOURNAL subcommand, to show the location of the
89 - VALUE LABELS can now assign value labels to long string
92 * Other language changes:
94 - The new DATASET commands replace the "scratch file" PSPP
95 extension, which is no longer supported.
97 - Strings may now include arbitrary Unicode code points specified
98 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
99 code point U+1D11E, the musical G clef character, may be
100 expressed as U'1D11E'.
102 See the "Tokens" section in the PSPP manual for more information.
104 - In previous versions of PSPP, in a string expressed in
105 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
106 bytes in the locale encoding. In this version of PSPP, X'hh'
107 syntax always expresses bytes in UTF-8 encoding.
109 See the "Tokens" section in the PSPP manual for more information.
111 * PSPPIRE graphical user interface improvements:
113 - Added support for non-ASCII characters in strings, labels and
116 - A "Split Window" function is available, which makes it easier to
117 see different parts of a large data file.
119 - Data files can now be opened by specifing their name as the first
120 argument. This means that on a properly configured desktop, double
121 clicking on an icon will open the file.
123 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
124 via using an "intelligent" application assistant dialog.
128 - The new "cairo" output driver supports output in PostScript, PDF,
129 and SVG formats. Its functionality is a superset of that of the
130 "postscript" driver, which has been removed. You must have Cairo
131 and Pango installed to build the "cairo" driver.
133 - Charts are now produced with Cairo and Pango, instead of libplot.
134 Without them, the new graphing features will not work. If you do
135 not have Cairo and Pango installed, you must run `configure' with
138 - The plain text output driver now properly supports multibyte UTF-8
139 characters, including double-width characters and combining
142 - Output to OpenDocument format is now supported.
144 - The HTML output is much improved.
146 * The "pspp" program has a new option --batch (or -b) that selects
147 "batch" syntax mode. In previous versions of PSPP this syntax mode
148 was the default. Now a new "auto" syntax mode is the default. In
149 "auto" mode, PSPP interprets most syntax files correctly regardless
150 of their intended syntax mode.
152 See the "Syntax Variants" section in the PSPP manual for more
155 * The "pspp" program has a new option --syntax-encoding that
156 specifies the encoding for syntax files listed on the command line,
157 as well as the default encoding for syntax files included with
158 INCLUDE or INSERT. The default is to accept the system locale
159 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
160 one the system file uses.
162 See the documentation for the INSERT command in the PSPP manual for
165 * Text data files that PRINT and WRITE creates now use the system
166 native line ends by default (CRLF on Windows, LF only elsewhere).
167 Use the new ENDS subcommand on FILE HANDLE to override the default.
169 * A new Perl module allows Perl programs to read and write PSPP
172 * A tutorial chapter has been added to the user manual.
174 Changes from 0.6.1 to 0.6.2:
178 - Dutch, thanks to Harry Thijssen.
180 - Brazilian Portuguese, thanks to Michel Boaventura.
182 Thanks for translations are also due to the coordinators at
183 translationproject.org.
185 * Statistical bug fixes:
187 - REGRESSION: Report correct standard error of the estimate (bug
190 - T-TEST: Report correct significance of paired sample T-test in
191 the common case (bug #26936) and corner cases. Thanks to Mike
192 Griffiths and Matej Cepl for reporting these bugs.
194 * Build fixes and changes:
196 - Fix build with GTK+ 2.17.4 and later.
198 - Make running "make" after running "configure" with different
199 settings reliably rebuild version.c.
201 - Cygwin and MinGW build fixes.
203 - Fixes for building with recent gnulib.
205 - The Makefile now honors two new variables, PSPP_LDFLAGS and
206 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
207 binaries, respectively. This makes building easier for some
210 - Fixes for "configure --enable-relocatable" (bug #25508).
212 * Data file bug fixes and changes:
214 - Fix reading text data files that contain a mix of white space
215 and commas. Now "a ,b" is treated as two fields containing "a"
216 and "b"; previously it was treated as three, with an empty field
219 - Fix writing corrupted .sav files on Windows.
221 - Fix writing variable labels longer than 252 bytes to save files.
222 Thanks to Robert Westlund for reporting this bug.
224 - Fix writing corrupted .por files (bug #26034).
226 - Fix reading .por files whose initial lines are not padded out
227 with spaces as expected.
229 - PSPP will no longer issue warnings about some .sav file records
230 or values that it does not understand. These warnings were
231 harmless, but needlessly alarmed some users.
233 - Fix crash reading empty string fields from PostgreSQL databases.
235 * Bug fixes that affect PSPP and PSPPIRE:
237 - Users may now control precision of output statistics. Instead
238 of hard coding the width and decimals of output numbers, respect
239 the default format in most instances. Counts are now normally
240 displayed with the format of the weight variable, if any.
242 - Fix crash when an INSERT command specifies the name of a file
243 that does not exist (bug #24569).
245 - Fix crash when CROSSTABS specifies a long-string variable (bugs
248 - Fix crash drawing pie charts with many segments.
250 - Fix crash when NUMERIC specifies an invalid format.
252 * PSPPIRE bug fixes and changes:
254 - On Windows, write the output file to the user's home directory
255 instead of the current directory, to better match user
258 - Some data editor fixes.
262 - Fix typo in BINOMIAL section of user manual (bug #25892).
264 Changes from 0.6.0 to 0.6.1:
266 * Statistical bug fixes:
268 - Report correct standardized regression coefficients in linear
269 regression output (bug #23567).
271 * Bug fixes that affect PSPP and PSPPIRE:
273 - Avoid crash with pie charts (bug #24014).
275 - Don't append % to count totals (bug #24003).
277 - Don't crash on bad input (bug #24031).
279 - Don't crash if "end data." is not left aligned (bug #24115).
281 - Change default workspace value to 64 MB, to avoid unnecessary
282 disk accesses on modern machines.
286 - Add ".sav" or ".por" suffix to filename when saving with Save_As
289 - Make it possible to reopen the output window on Windows (bug
292 - A POSIX regular expression library is now included and used
293 automatically if the host does not have one or has one that is
296 * Build fixes and changes:
298 - Work around bug in GSL that prevented build with recent GCC
299 versions without manually adding -fgnu89-inline to CFLAGS.
301 - Also warn about missing prerequisites as we encounter them (bug
304 - Distribute necessary files to allow users working from the
305 distributed tarball to configure with --enable-gui-tools.
307 - Append $(EXEEXT_FOR_BUILD) to output file name when building
308 q2c, fixing build problems on Windows.
310 - GSL 1.8 or later is now required.
312 - Build errors with --enable-relocatable were fixed.
314 * The German translations were removed, since native German speakers
315 found them too poor to be useful.
317 Changes from 0.4.0 to 0.6.0:
319 * The PSPP license is now version 3 or later of the GNU General
320 Public License. Previously, it was version 2 or later.
322 * PSPP now has a graphical interface, called PSPPIRE. This
323 interface allows you to enter data and variable definitions
324 interactively. Commands may be executed in syntax form, or by
325 using the interactive dialog boxes available from the dropdown
328 * A few sample syntax files are now included in the `examples'
331 * Numerous major and minor bugs have been fixed.
335 * The INSTALL file now reflects the details of how to install
336 PSPP. It is a tailored version of the generic installation
337 instructions, instead of a verbatim copy.
339 * iconv, which is ordinarily installed as part of a Unix-like
340 system, is now required. If you don't have it already, you can
341 install GNU libiconv (http://www.gnu.org/software/libiconv/).
343 * libxml2 and zlib are new optional dependencies. They are
344 required to use PSPP's support for reading Gnumeric files.
346 Statistical procedure changes:
348 * REGRESSION is a new procedure for fitting linear models to data
349 via least-squares estimation.
351 * NPAR TESTS is a new procedure for non-parametric tests. In this
352 release, it supports binomial and chi-square tests.
354 * RANK is a new procedure to rank variables. It supports numerous
357 * FREQUENCIES can now output histograms and pie charts. These
358 features were present in earlier releases, but not documented.
360 User interface changes:
362 * In many situations where PSPP once terminated with a fatal
363 error, PSPP now recovers and continues execution.
365 * PSPP is now able to start up and run even if it cannot find its
368 * Journaling of interactive commands to a disk file is now
369 implemented. By default, journaling is enabled, to a file named
370 `pspp.jnl' in the current directory. SET JOURNAL may be used to
373 * The use of `+' between syntax file names on the command line to
374 prevent the dictionary from being cleared between their
375 executions is no longer supported. All syntax files are now
376 executed as if `+' had been specified.
378 * The -d/--define and -u/--undef command line options are no
379 longer supported. Instead, use /usr/bin/env or shell primitives
380 to define or clear environment variables before invoking PSPP.
382 * If a syntax file named named `rc' is found in a configuration
383 directory (such as $HOME/.pspp), it is executed before any
384 syntax file specified on the command line. The -r or
385 --no-statrc command line option may be used to disable this
390 * Output configuration options have changed. Please refer to the
391 manual for a full description of the available options.
393 In consequence, you will need to reinstall your "devices" file.
394 "make install" will do this for you.
396 * Most error messages are now written to PSPP output files by
397 default. SET ERROR can be used to disable this behavior.
399 * When invoked interactively, PSPP now by default produces output
400 on the terminal, piping it through the "more" program.
401 Previously, by default output was written only to file
402 pspp.list. On most terminals, the page length used for output
403 automatically adapts to the terminal size, even if the terminal
408 - This driver now supports charts in output. Charts are written
409 as separate files that the main output file refers to. By
410 default, charts are written in PNG format to files named
411 pspp-1.png, pspp-2.png, and so on.
413 - Configurations are provided that use VT100 (and xterm)
414 line-drawing characters in tables. The option "-o list-vt100"
415 requests use of this device for output to pspp.list.
419 - The default paper size is now determined using the PAPERSIZE
420 environment variable, or the LC_PAPER locale category on
421 systems that support it. If these are not set, the default is
422 now A4, instead of US letter. To make US letter the default,
423 set PAPERSIZE to "letter" in your environment.
425 - Font metrics are now read from AFM files, instead of
426 Groff-format metrics files. PostScript fonts can now be
429 In consequence, you will need to install an AFM file for each
430 font used in PostScript output. "make install" will install
431 AFM files for the standard PostScript fonts, including the
432 ones that the PostScript driver uses by default.
434 - Standard paper sizes no longer need to be specified through a
435 configuration file. The "papersize" configuration file is no
436 longer needed, or supported.
438 - The PostScript prologue is no longer obtained from the
439 "ps-prologue" configuration file. This configuration file is
440 no longer needed, or supported.
444 - The HTML prologue is no longer obtained from the
445 "html-prologue" configuration file. This configuration file
446 is no longer needed, or supported.
448 Command language changes:
450 * The following commands are new:
452 - GET DATA, which currently supports reading Gnumeric files and
453 text data files. It will be extended later to read other
454 types of foreign data.
456 - CD, to change the current directory.
458 - INSERT, to execute a syntax file.
460 - DELETE VARIABLES, to remove variables from the active file
463 - ADD DOCUMENT, to add text to active file documents.
465 - CLOSE FILE HANDLE (a PSPP extension; see below).
467 - XEXPORT, a PSPP extension that is a transformation equivalent
470 * The following functions for transformation expressions are new:
472 - DATEDIFF, for computing the difference of two dates.
474 - DATESUM, for advancing a date by a specified duration.
476 - VALUELABEL, to obtain the value label for a value.
478 * PSPP now supports very long string variables (over 255 bytes
481 * MATCH FILES now supports the FIRST and LAST subcommands.
483 * Previous versions of PSPP prohibited using commands to both read and
484 write a single file at the same time. Now, PSPP allows this, and
485 the new version of the file atomically replaces the old version.
487 * The following commands are no longer available. They will be
488 re-implemented in a later release:
490 - CLEAR TRANSFORMATIONS
496 * The PROCESS IF command, which was deprecated, has been removed.
497 You may replace any usage of it by SELECT IF following
498 TEMPORARY, which has the same effect.
500 * The output format for variables created by VECTOR may now be
501 specified as part of the VECTOR syntax.
503 "Scratch files", a new PSPP extension:
505 A scratch file, like a system file, consists of a dictionary and
506 any number of cases. Small scratch files are stored in memory;
507 one that grows too large is written to disk. By default, any file
508 handle whose name begins with # is assumed to refer to a scratch
511 Scratch files can be used just about anywhere a system or portable
512 file can be used. Also, portable files are now allowed in most
513 places that system files were allowed in previous PSPP version.
515 A new CLOSE FILE HANDLE command allows the storage associated with
516 scratch files to be freed. It also allows file handles to be
517 reassigned to new files.
519 For more information on scratch files, refer to the "File Handles"
520 section in the PSPP manual. For specifics of what commands now
521 allow what kinds of files to be specified, refer to the
522 documentation on those particular commands.
526 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
527 translation, are now supported. Use FILE HANDLE to specify the
528 format of these files.
530 * Little-endian, big-endian, and VAX-endian formats are now
531 supported for integer binary formats when reading and writing
532 data files. The new RIB and WIB subcommands on the SET command
533 control endianness of integer data. The default is the host's
536 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
537 floating point binary formats when reading and writing data
538 files. The new RRB and WRB subcommands on the SET command
539 control the floating point format. The default is the host's
540 native floating point format.
542 * DATA LIST now supports the SKIP subcommand, to skip records at
543 the beginning of a file. For compatibility, DATA LIST now
544 treats N format as F format for FREE and LIST format input.
546 * The SAVE and XSAVE commands now support the UNSELECTED,
547 PERMISSIONS, NAMES, and MAP subcommands.
549 * The EXPORT command has been re-implemented to obtain better
550 results. Support for the UNSELECTED, DIGITS, and TYPE
551 subcommands has been added.
553 * For compatibility, PRINT now inserts a space at the beginning of
554 every output line, even lines that would otherwise be blank,
555 when OUTFILE is specified. (The behavior of WRITE is
558 * For compatibility, PRINT EJECT now inserts the digit `1' at the
559 beginning of each line that should begin a new page.
561 * For compatibility, WRITE now outputs the system-missing value as
562 a field filled with spaces. Binary formats are an exception.
563 (The behavior of PRINT is unchanged.)
567 * Input and output format descriptions have been rewritten. They
568 now precisely describe what is accepted on input and written on
571 * The descriptions of the PSPP system and portable file formats
572 have been extensively revised and improved.
574 For developers, the build system now requires Autoconf 2.60 and
577 Changes from 0.3.0 to 0.4.0:
579 Changes in build dependencies:
581 * The GNU Scientific Library (libgsl), version 1.6 or later, is
584 * libplot from GNU plotutils is optional. Without it, the new
585 graphing features will not work. If you do not have it
586 installed, you must run `configure' with --without-libplot.
588 * libgmp2 is no longer a dependency.
590 Newly implemented commands and statistical features:
592 * EXAMINE, including its graphing features.
594 * FREQUENCIES now supports percentiles.
602 * SORT CASES now sorts stably, that is, two cases with equal sort
603 criteria will be in the same relative order before and after the
606 * T-TEST (re-written).
608 * DATE and USE. These commands are parsed but otherwise ignored,
609 to enhance compatibility with certain command files that invoke
612 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
613 currently have no effect on PSPP output, but their values are
614 written to and read from system files and thus may affect
615 third-party software.
617 * SET EPOCH implemented.
619 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
622 * FILE HANDLE now supports custom tab widths.
624 Long variable names (and other identifiers) are now supported. Up
625 to the first 64 bytes of each identifier is significant. PSPP now
626 reads and writes system files compatible with SPSS version 12.
628 New --algorithm and --syntax command line options allow
629 SPSS-compatible or enhanced modes to be selected.
631 Support for transformation expressions has been rewritten and
632 significantly improved. Refer to the manual for details.
634 Calculation of moments (mean, standard deviation, kurtosis,
635 skewness) has been rewritten and should now be more accurate. In
636 --algorithm=enhanced mode moments may be more accurate than SPSS in
639 Numerous bugs have been fixed, too many to mention here. Many new
640 tests have been added, leading to the discovery and fixing of many
643 The ASCII output driver can now squeeze multiple blank lines into
646 Much of the code has been rewritten and refactored. It is now much
649 The FILE TYPE and REPEATING DATA commands have been disabled for
650 this release because their implementations were deemed too buggy to
651 be useful. They will be fixed and replaced in a future release.
653 New pspp-mode for Emacs (in pspp-mode.el).
655 Added rudimentary command-line completion for interactive input.
657 lib/julcal and lib/dcdflib are no longer used, so they have been
660 For developers, the build system now requires Autoconf 2.58 and
661 Automake 1.7. The included gettext has been updated to version
664 Some reports state that Texinfo 4.8, the latest version, may be
665 necessary to successfully format the documentation on some systems.
667 Version 0.3.0 changes since 0.2.3:
671 * Using alphanumeric variables in functions under AGGREGATE
674 * Under certain circumstances, the final case would be omitted
675 from the results of an AGGREGATE operation. Fixed.
677 * Undefined behavior was invoked by referencing a freed pointer
678 under certain circumstances. Fixed.
680 * A wrong record size was displayed when paging the active file to
683 * Not having enough temporary space for sorting caused a core
686 * Syntax errors in function descriptions on AGGREGATE caused core
689 * A null pointer was dereferenced, causing a core dump, when
690 PERCENTILES was specified on FREQUENCIES. This fixes the
691 problem, but PSPP still doesn't calculate percentiles.
693 * SORT always sorted in ascending order. Fixed.
695 * Some minor memory leaks in the expression parser were removed.
697 * Many assertions fixed for strict ANSI C compliance.
701 * SET ECHO ON now implemented, but turned off by default.
703 * PRINT specifier supported on END REPEAT.
707 * System libgmp2 library is used if installed instead of
708 unconditionally using the included libgmp2 subset.
710 * Extensive code cleanup, which continues.
712 * Added CORRELATIONS command parser, but not implemented.
714 Version 0.2.3 changes since 0.2.2:
718 * SPLIT FILE with a string variable caused a core dump. Fixed.
720 * Nested INCLUDEs didn't work. Fixed.
722 * The MATCH FILES procedure set the values of variables not present
723 to 0. It should have been SYSMIS. This is now fixed.
725 * The REMARK command was too aggressive about skipping lines. It
726 didn't like being the last command in a file.
728 * Comment parsing wasn't consistent with the rest of the code in its
729 idea of where one command ends and another starts. This meant
730 that sometimes commands would be mysteriously ignored. Thanks to
731 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
733 * The TABLE subcommand on MATCH FILES worked only erratically at
734 best. This fixes it. Thanks to Dr. Dirk Melcher
735 <BZN-mdksh@t-online.de> for reporting this bug.
737 * VARIABLE LABELS rejected a slash before the first variable
738 specification, contradicting the documentation. Thanks to Walter
739 M. Gray <graywm@northernc.on.ca> for reporting this bug.
741 * Because of an incorrect optimization in memory allocation,
742 CROSSTABS sometimes segfaulted when asked to output multiple
743 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
746 * CROSSTABS didn't display value labels for column and row
747 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
750 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
751 <BZN-mdksh@t-online.de> for reporting this bug.
753 * The TABLE subcommand on MATCH FILES worked only erratically at
754 best. This fixes it. Thanks to Dr. Dirk Melcher
755 <BZN-mdksh@t-online.de> for reporting this bug.
757 * VARIABLE LABELS rejected a slash before the first variable
758 specification, contradicting the documentation. Thanks to Walter
759 M. Gray <graywm@northernc.on.ca> for reporting this bug.
761 * Because of an incorrect optimization in memory allocation,
762 CROSSTABS sometimes segfaulted when asked to output multiple
763 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
766 * CROSSTABS didn't display value labels for column and row
767 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
770 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
771 <BZN-mdksh@t-online.de> for reporting this bug.
773 * MATCH FILES corrupted memory and dumped core on some syntax
776 * MATCH FILES should set numeric values not available to the
777 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
778 <BZN-mdksh@t-online.de> for reporting this bug.
780 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
781 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
785 * Some systems didn't like the way open_file was coded. Thanks to
786 Hankin <hankin@rogue.consultco.com> for pointing this out.
788 * The SAVE procedure didn't save long string variables properly.
789 Fixed by this patch. Thanks to Hankin
790 <hankin@rogue.consultco.com> for this patch.
792 * Minor documentation fixes for MATCH FILES.
794 Version 0.2.2 changes since 0.2.1:
798 * Fix behavior of PRINT SPACE for negative arguments.
800 * Fix reading some unusual system files.
802 * Fix LIST problems with very long variables. Thanks to Hankin
803 <hankin@dunno.com> for this bug report.
805 * Fix problems with some string format specifiers.
807 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
