9 * Charts are now rendered with colours from the Tango palette instead of fully
12 Changes from 0.8.0 to 0.8.1:
18 * Changes to existing commands:
20 - CROSSTABS: The requirement that one expected count must be less than five
21 before Fishers Exact Test will be reported has been removed.
23 * PSPPIRE graphical user interface improvements:
25 - A new set of icons has been contributed.
27 - Syntax windows now parse syntax in "auto" mode, which in practice
28 should mean that both "batch" and "interactive" syntax now works,
29 instead of just "interactive" syntax.
31 - The variable pane of data windows now include a Role column.
35 - System files written by IBM SPSS 21 are now read without warnings.
37 - System files written by "VOXCO INTERVIEWER 4.3" are now read
40 - PSPPIRE should now more gracefully handle syntax files that contain
43 Changes from 0.6.2 to 0.8.0:
60 - PRESERVE and RESTORE
64 - SAVE TRANSLATE to CSV and tab-delimited files
68 * Changes to existing commands:
70 - AUTORECODE has a new GROUP subcommand.
72 - CROSSTABS has been re-implemented to fix numerous bugs.
74 - EXAMINE: /MISSING=LISTWISE is now the default.
76 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
77 contains an INCLUDE or INSERT command, substitutions are not
78 applied to the included file.
80 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
82 - HOST has been updated to use more modern syntax.
84 - Most commands that work with data files now support a new
87 - MISSING VALUES can now assign missing values to long string
90 - ONEWAY: the POSTHOC subcommand is now implemented.
92 - The following new subcommands to NPAR TESTS have been implemented:
93 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
94 MCNEMAR, SIGN, WILCOXON, and RUNS
96 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
97 DPROMPT subcommands. The defaults are now fixed values.
99 - SHOW now has a JOURNAL subcommand, to show the location of the
102 - VALUE LABELS can now assign value labels to long string
105 * Other language changes:
107 - The new DATASET commands replace the "scratch file" PSPP
108 extension, which is no longer supported.
110 - Strings may now include arbitrary Unicode code points specified
111 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
112 code point U+1D11E, the musical G clef character, may be
113 expressed as U'1D11E'.
115 See the "Tokens" section in the PSPP manual for more information.
117 - In previous versions of PSPP, in a string expressed in
118 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
119 bytes in the locale encoding. In this version of PSPP, X'hh'
120 syntax always expresses bytes in UTF-8 encoding.
122 See the "Tokens" section in the PSPP manual for more information.
124 * PSPPIRE graphical user interface improvements:
126 - Added support for non-ASCII characters in strings, labels and
129 - A "Split Window" function is available, which makes it easier to
130 see different parts of a large data file.
132 - Data files can now be opened by specifing their name as the first
133 argument. This means that on a properly configured desktop, double
134 clicking on an icon will open the file.
136 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
137 via using an "intelligent" application assistant dialog.
141 - The new "cairo" output driver supports output in PostScript, PDF,
142 and SVG formats. Its functionality is a superset of that of the
143 "postscript" driver, which has been removed. You must have Cairo
144 and Pango installed to build the "cairo" driver.
146 - Charts are now produced with Cairo and Pango, instead of libplot.
147 Without them, the new graphing features will not work. If you do
148 not have Cairo and Pango installed, you must run `configure' with
151 - The plain text output driver now properly supports multibyte UTF-8
152 characters, including double-width characters and combining
155 - Output to OpenDocument format is now supported.
157 - The HTML output is much improved.
159 * The "pspp" program has a new option --batch (or -b) that selects
160 "batch" syntax mode. In previous versions of PSPP this syntax mode
161 was the default. Now a new "auto" syntax mode is the default. In
162 "auto" mode, PSPP interprets most syntax files correctly regardless
163 of their intended syntax mode.
165 See the "Syntax Variants" section in the PSPP manual for more
168 * The "pspp" program has a new option --syntax-encoding that
169 specifies the encoding for syntax files listed on the command line,
170 as well as the default encoding for syntax files included with
171 INCLUDE or INSERT. The default is to accept the system locale
172 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
173 one the system file uses.
175 See the documentation for the INSERT command in the PSPP manual for
178 * Text data files that PRINT and WRITE creates now use the system
179 native line ends by default (CRLF on Windows, LF only elsewhere).
180 Use the new ENDS subcommand on FILE HANDLE to override the default.
182 * A new Perl module allows Perl programs to read and write PSPP
185 * A tutorial chapter has been added to the user manual.
187 Changes from 0.6.1 to 0.6.2:
191 - Dutch, thanks to Harry Thijssen.
193 - Brazilian Portuguese, thanks to Michel Boaventura.
195 Thanks for translations are also due to the coordinators at
196 translationproject.org.
198 * Statistical bug fixes:
200 - REGRESSION: Report correct standard error of the estimate (bug
203 - T-TEST: Report correct significance of paired sample T-test in
204 the common case (bug #26936) and corner cases. Thanks to Mike
205 Griffiths and Matej Cepl for reporting these bugs.
207 * Build fixes and changes:
209 - Fix build with GTK+ 2.17.4 and later.
211 - Make running "make" after running "configure" with different
212 settings reliably rebuild version.c.
214 - Cygwin and MinGW build fixes.
216 - Fixes for building with recent gnulib.
218 - The Makefile now honors two new variables, PSPP_LDFLAGS and
219 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
220 binaries, respectively. This makes building easier for some
223 - Fixes for "configure --enable-relocatable" (bug #25508).
225 * Data file bug fixes and changes:
227 - Fix reading text data files that contain a mix of white space
228 and commas. Now "a ,b" is treated as two fields containing "a"
229 and "b"; previously it was treated as three, with an empty field
232 - Fix writing corrupted .sav files on Windows.
234 - Fix writing variable labels longer than 252 bytes to save files.
235 Thanks to Robert Westlund for reporting this bug.
237 - Fix writing corrupted .por files (bug #26034).
239 - Fix reading .por files whose initial lines are not padded out
240 with spaces as expected.
242 - PSPP will no longer issue warnings about some .sav file records
243 or values that it does not understand. These warnings were
244 harmless, but needlessly alarmed some users.
246 - Fix crash reading empty string fields from PostgreSQL databases.
248 * Bug fixes that affect PSPP and PSPPIRE:
250 - Users may now control precision of output statistics. Instead
251 of hard coding the width and decimals of output numbers, respect
252 the default format in most instances. Counts are now normally
253 displayed with the format of the weight variable, if any.
255 - Fix crash when an INSERT command specifies the name of a file
256 that does not exist (bug #24569).
258 - Fix crash when CROSSTABS specifies a long-string variable (bugs
261 - Fix crash drawing pie charts with many segments.
263 - Fix crash when NUMERIC specifies an invalid format.
265 * PSPPIRE bug fixes and changes:
267 - On Windows, write the output file to the user's home directory
268 instead of the current directory, to better match user
271 - Some data editor fixes.
275 - Fix typo in BINOMIAL section of user manual (bug #25892).
277 Changes from 0.6.0 to 0.6.1:
279 * Statistical bug fixes:
281 - Report correct standardized regression coefficients in linear
282 regression output (bug #23567).
284 * Bug fixes that affect PSPP and PSPPIRE:
286 - Avoid crash with pie charts (bug #24014).
288 - Don't append % to count totals (bug #24003).
290 - Don't crash on bad input (bug #24031).
292 - Don't crash if "end data." is not left aligned (bug #24115).
294 - Change default workspace value to 64 MB, to avoid unnecessary
295 disk accesses on modern machines.
299 - Add ".sav" or ".por" suffix to filename when saving with Save_As
302 - Make it possible to reopen the output window on Windows (bug
305 - A POSIX regular expression library is now included and used
306 automatically if the host does not have one or has one that is
309 * Build fixes and changes:
311 - Work around bug in GSL that prevented build with recent GCC
312 versions without manually adding -fgnu89-inline to CFLAGS.
314 - Also warn about missing prerequisites as we encounter them (bug
317 - Distribute necessary files to allow users working from the
318 distributed tarball to configure with --enable-gui-tools.
320 - Append $(EXEEXT_FOR_BUILD) to output file name when building
321 q2c, fixing build problems on Windows.
323 - GSL 1.8 or later is now required.
325 - Build errors with --enable-relocatable were fixed.
327 * The German translations were removed, since native German speakers
328 found them too poor to be useful.
330 Changes from 0.4.0 to 0.6.0:
332 * The PSPP license is now version 3 or later of the GNU General
333 Public License. Previously, it was version 2 or later.
335 * PSPP now has a graphical interface, called PSPPIRE. This
336 interface allows you to enter data and variable definitions
337 interactively. Commands may be executed in syntax form, or by
338 using the interactive dialog boxes available from the dropdown
341 * A few sample syntax files are now included in the `examples'
344 * Numerous major and minor bugs have been fixed.
348 * The INSTALL file now reflects the details of how to install
349 PSPP. It is a tailored version of the generic installation
350 instructions, instead of a verbatim copy.
352 * iconv, which is ordinarily installed as part of a Unix-like
353 system, is now required. If you don't have it already, you can
354 install GNU libiconv (http://www.gnu.org/software/libiconv/).
356 * libxml2 and zlib are new optional dependencies. They are
357 required to use PSPP's support for reading Gnumeric files.
359 Statistical procedure changes:
361 * REGRESSION is a new procedure for fitting linear models to data
362 via least-squares estimation.
364 * NPAR TESTS is a new procedure for non-parametric tests. In this
365 release, it supports binomial and chi-square tests.
367 * RANK is a new procedure to rank variables. It supports numerous
370 * FREQUENCIES can now output histograms and pie charts. These
371 features were present in earlier releases, but not documented.
373 User interface changes:
375 * In many situations where PSPP once terminated with a fatal
376 error, PSPP now recovers and continues execution.
378 * PSPP is now able to start up and run even if it cannot find its
381 * Journaling of interactive commands to a disk file is now
382 implemented. By default, journaling is enabled, to a file named
383 `pspp.jnl' in the current directory. SET JOURNAL may be used to
386 * The use of `+' between syntax file names on the command line to
387 prevent the dictionary from being cleared between their
388 executions is no longer supported. All syntax files are now
389 executed as if `+' had been specified.
391 * The -d/--define and -u/--undef command line options are no
392 longer supported. Instead, use /usr/bin/env or shell primitives
393 to define or clear environment variables before invoking PSPP.
395 * If a syntax file named named `rc' is found in a configuration
396 directory (such as $HOME/.pspp), it is executed before any
397 syntax file specified on the command line. The -r or
398 --no-statrc command line option may be used to disable this
403 * Output configuration options have changed. Please refer to the
404 manual for a full description of the available options.
406 In consequence, you will need to reinstall your "devices" file.
407 "make install" will do this for you.
409 * Most error messages are now written to PSPP output files by
410 default. SET ERROR can be used to disable this behavior.
412 * When invoked interactively, PSPP now by default produces output
413 on the terminal, piping it through the "more" program.
414 Previously, by default output was written only to file
415 pspp.list. On most terminals, the page length used for output
416 automatically adapts to the terminal size, even if the terminal
421 - This driver now supports charts in output. Charts are written
422 as separate files that the main output file refers to. By
423 default, charts are written in PNG format to files named
424 pspp-1.png, pspp-2.png, and so on.
426 - Configurations are provided that use VT100 (and xterm)
427 line-drawing characters in tables. The option "-o list-vt100"
428 requests use of this device for output to pspp.list.
432 - The default paper size is now determined using the PAPERSIZE
433 environment variable, or the LC_PAPER locale category on
434 systems that support it. If these are not set, the default is
435 now A4, instead of US letter. To make US letter the default,
436 set PAPERSIZE to "letter" in your environment.
438 - Font metrics are now read from AFM files, instead of
439 Groff-format metrics files. PostScript fonts can now be
442 In consequence, you will need to install an AFM file for each
443 font used in PostScript output. "make install" will install
444 AFM files for the standard PostScript fonts, including the
445 ones that the PostScript driver uses by default.
447 - Standard paper sizes no longer need to be specified through a
448 configuration file. The "papersize" configuration file is no
449 longer needed, or supported.
451 - The PostScript prologue is no longer obtained from the
452 "ps-prologue" configuration file. This configuration file is
453 no longer needed, or supported.
457 - The HTML prologue is no longer obtained from the
458 "html-prologue" configuration file. This configuration file
459 is no longer needed, or supported.
461 Command language changes:
463 * The following commands are new:
465 - GET DATA, which currently supports reading Gnumeric files and
466 text data files. It will be extended later to read other
467 types of foreign data.
469 - CD, to change the current directory.
471 - INSERT, to execute a syntax file.
473 - DELETE VARIABLES, to remove variables from the active file
476 - ADD DOCUMENT, to add text to active file documents.
478 - CLOSE FILE HANDLE (a PSPP extension; see below).
480 - XEXPORT, a PSPP extension that is a transformation equivalent
483 * The following functions for transformation expressions are new:
485 - DATEDIFF, for computing the difference of two dates.
487 - DATESUM, for advancing a date by a specified duration.
489 - VALUELABEL, to obtain the value label for a value.
491 * PSPP now supports very long string variables (over 255 bytes
494 * MATCH FILES now supports the FIRST and LAST subcommands.
496 * Previous versions of PSPP prohibited using commands to both read and
497 write a single file at the same time. Now, PSPP allows this, and
498 the new version of the file atomically replaces the old version.
500 * The following commands are no longer available. They will be
501 re-implemented in a later release:
503 - CLEAR TRANSFORMATIONS
509 * The PROCESS IF command, which was deprecated, has been removed.
510 You may replace any usage of it by SELECT IF following
511 TEMPORARY, which has the same effect.
513 * The output format for variables created by VECTOR may now be
514 specified as part of the VECTOR syntax.
516 "Scratch files", a new PSPP extension:
518 A scratch file, like a system file, consists of a dictionary and
519 any number of cases. Small scratch files are stored in memory;
520 one that grows too large is written to disk. By default, any file
521 handle whose name begins with # is assumed to refer to a scratch
524 Scratch files can be used just about anywhere a system or portable
525 file can be used. Also, portable files are now allowed in most
526 places that system files were allowed in previous PSPP version.
528 A new CLOSE FILE HANDLE command allows the storage associated with
529 scratch files to be freed. It also allows file handles to be
530 reassigned to new files.
532 For more information on scratch files, refer to the "File Handles"
533 section in the PSPP manual. For specifics of what commands now
534 allow what kinds of files to be specified, refer to the
535 documentation on those particular commands.
539 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
540 translation, are now supported. Use FILE HANDLE to specify the
541 format of these files.
543 * Little-endian, big-endian, and VAX-endian formats are now
544 supported for integer binary formats when reading and writing
545 data files. The new RIB and WIB subcommands on the SET command
546 control endianness of integer data. The default is the host's
549 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
550 floating point binary formats when reading and writing data
551 files. The new RRB and WRB subcommands on the SET command
552 control the floating point format. The default is the host's
553 native floating point format.
555 * DATA LIST now supports the SKIP subcommand, to skip records at
556 the beginning of a file. For compatibility, DATA LIST now
557 treats N format as F format for FREE and LIST format input.
559 * The SAVE and XSAVE commands now support the UNSELECTED,
560 PERMISSIONS, NAMES, and MAP subcommands.
562 * The EXPORT command has been re-implemented to obtain better
563 results. Support for the UNSELECTED, DIGITS, and TYPE
564 subcommands has been added.
566 * For compatibility, PRINT now inserts a space at the beginning of
567 every output line, even lines that would otherwise be blank,
568 when OUTFILE is specified. (The behavior of WRITE is
571 * For compatibility, PRINT EJECT now inserts the digit `1' at the
572 beginning of each line that should begin a new page.
574 * For compatibility, WRITE now outputs the system-missing value as
575 a field filled with spaces. Binary formats are an exception.
576 (The behavior of PRINT is unchanged.)
580 * Input and output format descriptions have been rewritten. They
581 now precisely describe what is accepted on input and written on
584 * The descriptions of the PSPP system and portable file formats
585 have been extensively revised and improved.
587 For developers, the build system now requires Autoconf 2.60 and
590 Changes from 0.3.0 to 0.4.0:
592 Changes in build dependencies:
594 * The GNU Scientific Library (libgsl), version 1.6 or later, is
597 * libplot from GNU plotutils is optional. Without it, the new
598 graphing features will not work. If you do not have it
599 installed, you must run `configure' with --without-libplot.
601 * libgmp2 is no longer a dependency.
603 Newly implemented commands and statistical features:
605 * EXAMINE, including its graphing features.
607 * FREQUENCIES now supports percentiles.
615 * SORT CASES now sorts stably, that is, two cases with equal sort
616 criteria will be in the same relative order before and after the
619 * T-TEST (re-written).
621 * DATE and USE. These commands are parsed but otherwise ignored,
622 to enhance compatibility with certain command files that invoke
625 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
626 currently have no effect on PSPP output, but their values are
627 written to and read from system files and thus may affect
628 third-party software.
630 * SET EPOCH implemented.
632 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
635 * FILE HANDLE now supports custom tab widths.
637 Long variable names (and other identifiers) are now supported. Up
638 to the first 64 bytes of each identifier is significant. PSPP now
639 reads and writes system files compatible with SPSS version 12.
641 New --algorithm and --syntax command line options allow
642 SPSS-compatible or enhanced modes to be selected.
644 Support for transformation expressions has been rewritten and
645 significantly improved. Refer to the manual for details.
647 Calculation of moments (mean, standard deviation, kurtosis,
648 skewness) has been rewritten and should now be more accurate. In
649 --algorithm=enhanced mode moments may be more accurate than SPSS in
652 Numerous bugs have been fixed, too many to mention here. Many new
653 tests have been added, leading to the discovery and fixing of many
656 The ASCII output driver can now squeeze multiple blank lines into
659 Much of the code has been rewritten and refactored. It is now much
662 The FILE TYPE and REPEATING DATA commands have been disabled for
663 this release because their implementations were deemed too buggy to
664 be useful. They will be fixed and replaced in a future release.
666 New pspp-mode for Emacs (in pspp-mode.el).
668 Added rudimentary command-line completion for interactive input.
670 lib/julcal and lib/dcdflib are no longer used, so they have been
673 For developers, the build system now requires Autoconf 2.58 and
674 Automake 1.7. The included gettext has been updated to version
677 Some reports state that Texinfo 4.8, the latest version, may be
678 necessary to successfully format the documentation on some systems.
680 Version 0.3.0 changes since 0.2.3:
684 * Using alphanumeric variables in functions under AGGREGATE
687 * Under certain circumstances, the final case would be omitted
688 from the results of an AGGREGATE operation. Fixed.
690 * Undefined behavior was invoked by referencing a freed pointer
691 under certain circumstances. Fixed.
693 * A wrong record size was displayed when paging the active file to
696 * Not having enough temporary space for sorting caused a core
699 * Syntax errors in function descriptions on AGGREGATE caused core
702 * A null pointer was dereferenced, causing a core dump, when
703 PERCENTILES was specified on FREQUENCIES. This fixes the
704 problem, but PSPP still doesn't calculate percentiles.
706 * SORT always sorted in ascending order. Fixed.
708 * Some minor memory leaks in the expression parser were removed.
710 * Many assertions fixed for strict ANSI C compliance.
714 * SET ECHO ON now implemented, but turned off by default.
716 * PRINT specifier supported on END REPEAT.
720 * System libgmp2 library is used if installed instead of
721 unconditionally using the included libgmp2 subset.
723 * Extensive code cleanup, which continues.
725 * Added CORRELATIONS command parser, but not implemented.
727 Version 0.2.3 changes since 0.2.2:
731 * SPLIT FILE with a string variable caused a core dump. Fixed.
733 * Nested INCLUDEs didn't work. Fixed.
735 * The MATCH FILES procedure set the values of variables not present
736 to 0. It should have been SYSMIS. This is now fixed.
738 * The REMARK command was too aggressive about skipping lines. It
739 didn't like being the last command in a file.
741 * Comment parsing wasn't consistent with the rest of the code in its
742 idea of where one command ends and another starts. This meant
743 that sometimes commands would be mysteriously ignored. Thanks to
744 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
746 * The TABLE subcommand on MATCH FILES worked only erratically at
747 best. This fixes it. Thanks to Dr. Dirk Melcher
748 <BZN-mdksh@t-online.de> for reporting this bug.
750 * VARIABLE LABELS rejected a slash before the first variable
751 specification, contradicting the documentation. Thanks to Walter
752 M. Gray <graywm@northernc.on.ca> for reporting this bug.
754 * Because of an incorrect optimization in memory allocation,
755 CROSSTABS sometimes segfaulted when asked to output multiple
756 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
759 * CROSSTABS didn't display value labels for column and row
760 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
763 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
764 <BZN-mdksh@t-online.de> for reporting this bug.
766 * The TABLE subcommand on MATCH FILES worked only erratically at
767 best. This fixes it. Thanks to Dr. Dirk Melcher
768 <BZN-mdksh@t-online.de> for reporting this bug.
770 * VARIABLE LABELS rejected a slash before the first variable
771 specification, contradicting the documentation. Thanks to Walter
772 M. Gray <graywm@northernc.on.ca> for reporting this bug.
774 * Because of an incorrect optimization in memory allocation,
775 CROSSTABS sometimes segfaulted when asked to output multiple
776 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
779 * CROSSTABS didn't display value labels for column and row
780 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
783 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
784 <BZN-mdksh@t-online.de> for reporting this bug.
786 * MATCH FILES corrupted memory and dumped core on some syntax
789 * MATCH FILES should set numeric values not available to the
790 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
791 <BZN-mdksh@t-online.de> for reporting this bug.
793 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
794 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
798 * Some systems didn't like the way open_file was coded. Thanks to
799 Hankin <hankin@rogue.consultco.com> for pointing this out.
801 * The SAVE procedure didn't save long string variables properly.
802 Fixed by this patch. Thanks to Hankin
803 <hankin@rogue.consultco.com> for this patch.
805 * Minor documentation fixes for MATCH FILES.
807 Version 0.2.2 changes since 0.2.1:
