5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
7 Changes from 0.8.0 to 0.8.1:
13 * Changes to existing commands:
15 - CROSSTABS: The requirement that one expected count must be less than five
16 before Fishers Exact Test will be reported has been removed.
18 * PSPPIRE graphical user interface improvements:
20 - A new set of icons has been contributed.
22 - Syntax windows now parse syntax in "auto" mode, which in practice
23 should mean that both "batch" and "interactive" syntax now works,
24 instead of just "interactive" syntax.
26 - The variable pane of data windows now include a Role column.
30 - System files written by IBM SPSS 21 are now read without warnings.
32 - System files written by "VOXCO INTERVIEWER 4.3" are now read
35 - PSPPIRE should now more gracefully handle syntax files that contain
38 Changes from 0.6.2 to 0.8.0:
55 - PRESERVE and RESTORE
59 - SAVE TRANSLATE to CSV and tab-delimited files
63 * Changes to existing commands:
65 - AUTORECODE has a new GROUP subcommand.
67 - CROSSTABS has been re-implemented to fix numerous bugs.
69 - EXAMINE: /MISSING=LISTWISE is now the default.
71 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
72 contains an INCLUDE or INSERT command, substitutions are not
73 applied to the included file.
75 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
77 - HOST has been updated to use more modern syntax.
79 - Most commands that work with data files now support a new
82 - MISSING VALUES can now assign missing values to long string
85 - ONEWAY: the POSTHOC subcommand is now implemented.
87 - The following new subcommands to NPAR TESTS have been implemented:
88 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
89 MCNEMAR, SIGN, WILCOXON, and RUNS
91 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
92 DPROMPT subcommands. The defaults are now fixed values.
94 - SHOW now has a JOURNAL subcommand, to show the location of the
97 - VALUE LABELS can now assign value labels to long string
100 * Other language changes:
102 - The new DATASET commands replace the "scratch file" PSPP
103 extension, which is no longer supported.
105 - Strings may now include arbitrary Unicode code points specified
106 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
107 code point U+1D11E, the musical G clef character, may be
108 expressed as U'1D11E'.
110 See the "Tokens" section in the PSPP manual for more information.
112 - In previous versions of PSPP, in a string expressed in
113 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
114 bytes in the locale encoding. In this version of PSPP, X'hh'
115 syntax always expresses bytes in UTF-8 encoding.
117 See the "Tokens" section in the PSPP manual for more information.
119 * PSPPIRE graphical user interface improvements:
121 - Added support for non-ASCII characters in strings, labels and
124 - A "Split Window" function is available, which makes it easier to
125 see different parts of a large data file.
127 - Data files can now be opened by specifing their name as the first
128 argument. This means that on a properly configured desktop, double
129 clicking on an icon will open the file.
131 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
132 via using an "intelligent" application assistant dialog.
136 - The new "cairo" output driver supports output in PostScript, PDF,
137 and SVG formats. Its functionality is a superset of that of the
138 "postscript" driver, which has been removed. You must have Cairo
139 and Pango installed to build the "cairo" driver.
141 - Charts are now produced with Cairo and Pango, instead of libplot.
142 Without them, the new graphing features will not work. If you do
143 not have Cairo and Pango installed, you must run `configure' with
146 - The plain text output driver now properly supports multibyte UTF-8
147 characters, including double-width characters and combining
150 - Output to OpenDocument format is now supported.
152 - The HTML output is much improved.
154 * The "pspp" program has a new option --batch (or -b) that selects
155 "batch" syntax mode. In previous versions of PSPP this syntax mode
156 was the default. Now a new "auto" syntax mode is the default. In
157 "auto" mode, PSPP interprets most syntax files correctly regardless
158 of their intended syntax mode.
160 See the "Syntax Variants" section in the PSPP manual for more
163 * The "pspp" program has a new option --syntax-encoding that
164 specifies the encoding for syntax files listed on the command line,
165 as well as the default encoding for syntax files included with
166 INCLUDE or INSERT. The default is to accept the system locale
167 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
168 one the system file uses.
170 See the documentation for the INSERT command in the PSPP manual for
173 * Text data files that PRINT and WRITE creates now use the system
174 native line ends by default (CRLF on Windows, LF only elsewhere).
175 Use the new ENDS subcommand on FILE HANDLE to override the default.
177 * A new Perl module allows Perl programs to read and write PSPP
180 * A tutorial chapter has been added to the user manual.
182 Changes from 0.6.1 to 0.6.2:
186 - Dutch, thanks to Harry Thijssen.
188 - Brazilian Portuguese, thanks to Michel Boaventura.
190 Thanks for translations are also due to the coordinators at
191 translationproject.org.
193 * Statistical bug fixes:
195 - REGRESSION: Report correct standard error of the estimate (bug
198 - T-TEST: Report correct significance of paired sample T-test in
199 the common case (bug #26936) and corner cases. Thanks to Mike
200 Griffiths and Matej Cepl for reporting these bugs.
202 * Build fixes and changes:
204 - Fix build with GTK+ 2.17.4 and later.
206 - Make running "make" after running "configure" with different
207 settings reliably rebuild version.c.
209 - Cygwin and MinGW build fixes.
211 - Fixes for building with recent gnulib.
213 - The Makefile now honors two new variables, PSPP_LDFLAGS and
214 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
215 binaries, respectively. This makes building easier for some
218 - Fixes for "configure --enable-relocatable" (bug #25508).
220 * Data file bug fixes and changes:
222 - Fix reading text data files that contain a mix of white space
223 and commas. Now "a ,b" is treated as two fields containing "a"
224 and "b"; previously it was treated as three, with an empty field
227 - Fix writing corrupted .sav files on Windows.
229 - Fix writing variable labels longer than 252 bytes to save files.
230 Thanks to Robert Westlund for reporting this bug.
232 - Fix writing corrupted .por files (bug #26034).
234 - Fix reading .por files whose initial lines are not padded out
235 with spaces as expected.
237 - PSPP will no longer issue warnings about some .sav file records
238 or values that it does not understand. These warnings were
239 harmless, but needlessly alarmed some users.
241 - Fix crash reading empty string fields from PostgreSQL databases.
243 * Bug fixes that affect PSPP and PSPPIRE:
245 - Users may now control precision of output statistics. Instead
246 of hard coding the width and decimals of output numbers, respect
247 the default format in most instances. Counts are now normally
248 displayed with the format of the weight variable, if any.
250 - Fix crash when an INSERT command specifies the name of a file
251 that does not exist (bug #24569).
253 - Fix crash when CROSSTABS specifies a long-string variable (bugs
256 - Fix crash drawing pie charts with many segments.
258 - Fix crash when NUMERIC specifies an invalid format.
260 * PSPPIRE bug fixes and changes:
262 - On Windows, write the output file to the user's home directory
263 instead of the current directory, to better match user
266 - Some data editor fixes.
270 - Fix typo in BINOMIAL section of user manual (bug #25892).
272 Changes from 0.6.0 to 0.6.1:
274 * Statistical bug fixes:
276 - Report correct standardized regression coefficients in linear
277 regression output (bug #23567).
279 * Bug fixes that affect PSPP and PSPPIRE:
281 - Avoid crash with pie charts (bug #24014).
283 - Don't append % to count totals (bug #24003).
285 - Don't crash on bad input (bug #24031).
287 - Don't crash if "end data." is not left aligned (bug #24115).
289 - Change default workspace value to 64 MB, to avoid unnecessary
290 disk accesses on modern machines.
294 - Add ".sav" or ".por" suffix to filename when saving with Save_As
297 - Make it possible to reopen the output window on Windows (bug
300 - A POSIX regular expression library is now included and used
301 automatically if the host does not have one or has one that is
304 * Build fixes and changes:
306 - Work around bug in GSL that prevented build with recent GCC
307 versions without manually adding -fgnu89-inline to CFLAGS.
309 - Also warn about missing prerequisites as we encounter them (bug
312 - Distribute necessary files to allow users working from the
313 distributed tarball to configure with --enable-gui-tools.
315 - Append $(EXEEXT_FOR_BUILD) to output file name when building
316 q2c, fixing build problems on Windows.
318 - GSL 1.8 or later is now required.
320 - Build errors with --enable-relocatable were fixed.
322 * The German translations were removed, since native German speakers
323 found them too poor to be useful.
325 Changes from 0.4.0 to 0.6.0:
327 * The PSPP license is now version 3 or later of the GNU General
328 Public License. Previously, it was version 2 or later.
330 * PSPP now has a graphical interface, called PSPPIRE. This
331 interface allows you to enter data and variable definitions
332 interactively. Commands may be executed in syntax form, or by
333 using the interactive dialog boxes available from the dropdown
336 * A few sample syntax files are now included in the `examples'
339 * Numerous major and minor bugs have been fixed.
343 * The INSTALL file now reflects the details of how to install
344 PSPP. It is a tailored version of the generic installation
345 instructions, instead of a verbatim copy.
347 * iconv, which is ordinarily installed as part of a Unix-like
348 system, is now required. If you don't have it already, you can
349 install GNU libiconv (http://www.gnu.org/software/libiconv/).
351 * libxml2 and zlib are new optional dependencies. They are
352 required to use PSPP's support for reading Gnumeric files.
354 Statistical procedure changes:
356 * REGRESSION is a new procedure for fitting linear models to data
357 via least-squares estimation.
359 * NPAR TESTS is a new procedure for non-parametric tests. In this
360 release, it supports binomial and chi-square tests.
362 * RANK is a new procedure to rank variables. It supports numerous
365 * FREQUENCIES can now output histograms and pie charts. These
366 features were present in earlier releases, but not documented.
368 User interface changes:
370 * In many situations where PSPP once terminated with a fatal
371 error, PSPP now recovers and continues execution.
373 * PSPP is now able to start up and run even if it cannot find its
376 * Journaling of interactive commands to a disk file is now
377 implemented. By default, journaling is enabled, to a file named
378 `pspp.jnl' in the current directory. SET JOURNAL may be used to
381 * The use of `+' between syntax file names on the command line to
382 prevent the dictionary from being cleared between their
383 executions is no longer supported. All syntax files are now
384 executed as if `+' had been specified.
386 * The -d/--define and -u/--undef command line options are no
387 longer supported. Instead, use /usr/bin/env or shell primitives
388 to define or clear environment variables before invoking PSPP.
390 * If a syntax file named named `rc' is found in a configuration
391 directory (such as $HOME/.pspp), it is executed before any
392 syntax file specified on the command line. The -r or
393 --no-statrc command line option may be used to disable this
398 * Output configuration options have changed. Please refer to the
399 manual for a full description of the available options.
401 In consequence, you will need to reinstall your "devices" file.
402 "make install" will do this for you.
404 * Most error messages are now written to PSPP output files by
405 default. SET ERROR can be used to disable this behavior.
407 * When invoked interactively, PSPP now by default produces output
408 on the terminal, piping it through the "more" program.
409 Previously, by default output was written only to file
410 pspp.list. On most terminals, the page length used for output
411 automatically adapts to the terminal size, even if the terminal
416 - This driver now supports charts in output. Charts are written
417 as separate files that the main output file refers to. By
418 default, charts are written in PNG format to files named
419 pspp-1.png, pspp-2.png, and so on.
421 - Configurations are provided that use VT100 (and xterm)
422 line-drawing characters in tables. The option "-o list-vt100"
423 requests use of this device for output to pspp.list.
427 - The default paper size is now determined using the PAPERSIZE
428 environment variable, or the LC_PAPER locale category on
429 systems that support it. If these are not set, the default is
430 now A4, instead of US letter. To make US letter the default,
431 set PAPERSIZE to "letter" in your environment.
433 - Font metrics are now read from AFM files, instead of
434 Groff-format metrics files. PostScript fonts can now be
437 In consequence, you will need to install an AFM file for each
438 font used in PostScript output. "make install" will install
439 AFM files for the standard PostScript fonts, including the
440 ones that the PostScript driver uses by default.
442 - Standard paper sizes no longer need to be specified through a
443 configuration file. The "papersize" configuration file is no
444 longer needed, or supported.
446 - The PostScript prologue is no longer obtained from the
447 "ps-prologue" configuration file. This configuration file is
448 no longer needed, or supported.
452 - The HTML prologue is no longer obtained from the
453 "html-prologue" configuration file. This configuration file
454 is no longer needed, or supported.
456 Command language changes:
458 * The following commands are new:
460 - GET DATA, which currently supports reading Gnumeric files and
461 text data files. It will be extended later to read other
462 types of foreign data.
464 - CD, to change the current directory.
466 - INSERT, to execute a syntax file.
468 - DELETE VARIABLES, to remove variables from the active file
471 - ADD DOCUMENT, to add text to active file documents.
473 - CLOSE FILE HANDLE (a PSPP extension; see below).
475 - XEXPORT, a PSPP extension that is a transformation equivalent
478 * The following functions for transformation expressions are new:
480 - DATEDIFF, for computing the difference of two dates.
482 - DATESUM, for advancing a date by a specified duration.
484 - VALUELABEL, to obtain the value label for a value.
486 * PSPP now supports very long string variables (over 255 bytes
489 * MATCH FILES now supports the FIRST and LAST subcommands.
491 * Previous versions of PSPP prohibited using commands to both read and
492 write a single file at the same time. Now, PSPP allows this, and
493 the new version of the file atomically replaces the old version.
495 * The following commands are no longer available. They will be
496 re-implemented in a later release:
498 - CLEAR TRANSFORMATIONS
504 * The PROCESS IF command, which was deprecated, has been removed.
505 You may replace any usage of it by SELECT IF following
506 TEMPORARY, which has the same effect.
508 * The output format for variables created by VECTOR may now be
509 specified as part of the VECTOR syntax.
511 "Scratch files", a new PSPP extension:
513 A scratch file, like a system file, consists of a dictionary and
514 any number of cases. Small scratch files are stored in memory;
515 one that grows too large is written to disk. By default, any file
516 handle whose name begins with # is assumed to refer to a scratch
519 Scratch files can be used just about anywhere a system or portable
520 file can be used. Also, portable files are now allowed in most
521 places that system files were allowed in previous PSPP version.
523 A new CLOSE FILE HANDLE command allows the storage associated with
524 scratch files to be freed. It also allows file handles to be
525 reassigned to new files.
527 For more information on scratch files, refer to the "File Handles"
528 section in the PSPP manual. For specifics of what commands now
529 allow what kinds of files to be specified, refer to the
530 documentation on those particular commands.
534 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
535 translation, are now supported. Use FILE HANDLE to specify the
536 format of these files.
538 * Little-endian, big-endian, and VAX-endian formats are now
539 supported for integer binary formats when reading and writing
540 data files. The new RIB and WIB subcommands on the SET command
541 control endianness of integer data. The default is the host's
544 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
545 floating point binary formats when reading and writing data
546 files. The new RRB and WRB subcommands on the SET command
547 control the floating point format. The default is the host's
548 native floating point format.
550 * DATA LIST now supports the SKIP subcommand, to skip records at
551 the beginning of a file. For compatibility, DATA LIST now
552 treats N format as F format for FREE and LIST format input.
554 * The SAVE and XSAVE commands now support the UNSELECTED,
555 PERMISSIONS, NAMES, and MAP subcommands.
557 * The EXPORT command has been re-implemented to obtain better
558 results. Support for the UNSELECTED, DIGITS, and TYPE
559 subcommands has been added.
561 * For compatibility, PRINT now inserts a space at the beginning of
562 every output line, even lines that would otherwise be blank,
563 when OUTFILE is specified. (The behavior of WRITE is
566 * For compatibility, PRINT EJECT now inserts the digit `1' at the
567 beginning of each line that should begin a new page.
569 * For compatibility, WRITE now outputs the system-missing value as
570 a field filled with spaces. Binary formats are an exception.
571 (The behavior of PRINT is unchanged.)
575 * Input and output format descriptions have been rewritten. They
576 now precisely describe what is accepted on input and written on
579 * The descriptions of the PSPP system and portable file formats
580 have been extensively revised and improved.
582 For developers, the build system now requires Autoconf 2.60 and
585 Changes from 0.3.0 to 0.4.0:
587 Changes in build dependencies:
589 * The GNU Scientific Library (libgsl), version 1.6 or later, is
592 * libplot from GNU plotutils is optional. Without it, the new
593 graphing features will not work. If you do not have it
594 installed, you must run `configure' with --without-libplot.
596 * libgmp2 is no longer a dependency.
598 Newly implemented commands and statistical features:
600 * EXAMINE, including its graphing features.
602 * FREQUENCIES now supports percentiles.
610 * SORT CASES now sorts stably, that is, two cases with equal sort
611 criteria will be in the same relative order before and after the
614 * T-TEST (re-written).
616 * DATE and USE. These commands are parsed but otherwise ignored,
617 to enhance compatibility with certain command files that invoke
620 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
621 currently have no effect on PSPP output, but their values are
622 written to and read from system files and thus may affect
623 third-party software.
625 * SET EPOCH implemented.
627 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
630 * FILE HANDLE now supports custom tab widths.
632 Long variable names (and other identifiers) are now supported. Up
633 to the first 64 bytes of each identifier is significant. PSPP now
634 reads and writes system files compatible with SPSS version 12.
636 New --algorithm and --syntax command line options allow
637 SPSS-compatible or enhanced modes to be selected.
639 Support for transformation expressions has been rewritten and
640 significantly improved. Refer to the manual for details.
642 Calculation of moments (mean, standard deviation, kurtosis,
643 skewness) has been rewritten and should now be more accurate. In
644 --algorithm=enhanced mode moments may be more accurate than SPSS in
647 Numerous bugs have been fixed, too many to mention here. Many new
648 tests have been added, leading to the discovery and fixing of many
651 The ASCII output driver can now squeeze multiple blank lines into
654 Much of the code has been rewritten and refactored. It is now much
657 The FILE TYPE and REPEATING DATA commands have been disabled for
658 this release because their implementations were deemed too buggy to
659 be useful. They will be fixed and replaced in a future release.
661 New pspp-mode for Emacs (in pspp-mode.el).
663 Added rudimentary command-line completion for interactive input.
665 lib/julcal and lib/dcdflib are no longer used, so they have been
668 For developers, the build system now requires Autoconf 2.58 and
669 Automake 1.7. The included gettext has been updated to version
672 Some reports state that Texinfo 4.8, the latest version, may be
673 necessary to successfully format the documentation on some systems.
675 Version 0.3.0 changes since 0.2.3:
679 * Using alphanumeric variables in functions under AGGREGATE
682 * Under certain circumstances, the final case would be omitted
683 from the results of an AGGREGATE operation. Fixed.
685 * Undefined behavior was invoked by referencing a freed pointer
686 under certain circumstances. Fixed.
688 * A wrong record size was displayed when paging the active file to
691 * Not having enough temporary space for sorting caused a core
694 * Syntax errors in function descriptions on AGGREGATE caused core
697 * A null pointer was dereferenced, causing a core dump, when
698 PERCENTILES was specified on FREQUENCIES. This fixes the
699 problem, but PSPP still doesn't calculate percentiles.
701 * SORT always sorted in ascending order. Fixed.
703 * Some minor memory leaks in the expression parser were removed.
705 * Many assertions fixed for strict ANSI C compliance.
709 * SET ECHO ON now implemented, but turned off by default.
711 * PRINT specifier supported on END REPEAT.
715 * System libgmp2 library is used if installed instead of
716 unconditionally using the included libgmp2 subset.
718 * Extensive code cleanup, which continues.
720 * Added CORRELATIONS command parser, but not implemented.
722 Version 0.2.3 changes since 0.2.2:
726 * SPLIT FILE with a string variable caused a core dump. Fixed.
728 * Nested INCLUDEs didn't work. Fixed.
730 * The MATCH FILES procedure set the values of variables not present
731 to 0. It should have been SYSMIS. This is now fixed.
733 * The REMARK command was too aggressive about skipping lines. It
734 didn't like being the last command in a file.
736 * Comment parsing wasn't consistent with the rest of the code in its
737 idea of where one command ends and another starts. This meant
738 that sometimes commands would be mysteriously ignored. Thanks to
739 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
741 * The TABLE subcommand on MATCH FILES worked only erratically at
742 best. This fixes it. Thanks to Dr. Dirk Melcher
743 <BZN-mdksh@t-online.de> for reporting this bug.
745 * VARIABLE LABELS rejected a slash before the first variable
746 specification, contradicting the documentation. Thanks to Walter
747 M. Gray <graywm@northernc.on.ca> for reporting this bug.
749 * Because of an incorrect optimization in memory allocation,
750 CROSSTABS sometimes segfaulted when asked to output multiple
751 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
754 * CROSSTABS didn't display value labels for column and row
755 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
758 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
759 <BZN-mdksh@t-online.de> for reporting this bug.
761 * The TABLE subcommand on MATCH FILES worked only erratically at
762 best. This fixes it. Thanks to Dr. Dirk Melcher
763 <BZN-mdksh@t-online.de> for reporting this bug.
765 * VARIABLE LABELS rejected a slash before the first variable
766 specification, contradicting the documentation. Thanks to Walter
767 M. Gray <graywm@northernc.on.ca> for reporting this bug.
769 * Because of an incorrect optimization in memory allocation,
770 CROSSTABS sometimes segfaulted when asked to output multiple
771 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
774 * CROSSTABS didn't display value labels for column and row
775 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
778 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
779 <BZN-mdksh@t-online.de> for reporting this bug.
781 * MATCH FILES corrupted memory and dumped core on some syntax
784 * MATCH FILES should set numeric values not available to the
785 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
786 <BZN-mdksh@t-online.de> for reporting this bug.
788 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
789 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
793 * Some systems didn't like the way open_file was coded. Thanks to
794 Hankin <hankin@rogue.consultco.com> for pointing this out.
796 * The SAVE procedure didn't save long string variables properly.
797 Fixed by this patch. Thanks to Hankin
798 <hankin@rogue.consultco.com> for this patch.
800 * Minor documentation fixes for MATCH FILES.
802 Version 0.2.2 changes since 0.2.1:
806 * Fix behavior of PRINT SPACE for negative arguments.
