5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
9 * Charts are now rendered with colours from the Tango palette instead
10 of fully saturated primaries.
12 * Missing values for long string variables are now read from and
13 written to system files in an SPSS-compatible fashion.
15 (Earlier versions of PSPP that supported missing values for long
16 string variables wrote them to system files in an SPSS-incompatible
17 way. To fix the problem, read the system file with this version of
18 PSPP and then save a new copy of it.)
20 Changes from 0.8.0 to 0.8.1:
26 * Changes to existing commands:
28 - CROSSTABS: The requirement that one expected count must be less than five
29 before Fishers Exact Test will be reported has been removed.
31 * PSPPIRE graphical user interface improvements:
33 - A new set of icons has been contributed.
35 - Syntax windows now parse syntax in "auto" mode, which in practice
36 should mean that both "batch" and "interactive" syntax now works,
37 instead of just "interactive" syntax.
39 - The variable pane of data windows now include a Role column.
43 - System files written by IBM SPSS 21 are now read without warnings.
45 - System files written by "VOXCO INTERVIEWER 4.3" are now read
48 - PSPPIRE should now more gracefully handle syntax files that contain
51 Changes from 0.6.2 to 0.8.0:
68 - PRESERVE and RESTORE
72 - SAVE TRANSLATE to CSV and tab-delimited files
76 * Changes to existing commands:
78 - AUTORECODE has a new GROUP subcommand.
80 - CROSSTABS has been re-implemented to fix numerous bugs.
82 - EXAMINE: /MISSING=LISTWISE is now the default.
84 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
85 contains an INCLUDE or INSERT command, substitutions are not
86 applied to the included file.
88 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
90 - HOST has been updated to use more modern syntax.
92 - Most commands that work with data files now support a new
95 - MISSING VALUES can now assign missing values to long string
98 - ONEWAY: the POSTHOC subcommand is now implemented.
100 - The following new subcommands to NPAR TESTS have been implemented:
101 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
102 MCNEMAR, SIGN, WILCOXON, and RUNS
104 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
105 DPROMPT subcommands. The defaults are now fixed values.
107 - SHOW now has a JOURNAL subcommand, to show the location of the
110 - VALUE LABELS can now assign value labels to long string
113 * Other language changes:
115 - The new DATASET commands replace the "scratch file" PSPP
116 extension, which is no longer supported.
118 - Strings may now include arbitrary Unicode code points specified
119 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
120 code point U+1D11E, the musical G clef character, may be
121 expressed as U'1D11E'.
123 See the "Tokens" section in the PSPP manual for more information.
125 - In previous versions of PSPP, in a string expressed in
126 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
127 bytes in the locale encoding. In this version of PSPP, X'hh'
128 syntax always expresses bytes in UTF-8 encoding.
130 See the "Tokens" section in the PSPP manual for more information.
132 * PSPPIRE graphical user interface improvements:
134 - Added support for non-ASCII characters in strings, labels and
137 - A "Split Window" function is available, which makes it easier to
138 see different parts of a large data file.
140 - Data files can now be opened by specifing their name as the first
141 argument. This means that on a properly configured desktop, double
142 clicking on an icon will open the file.
144 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
145 via using an "intelligent" application assistant dialog.
149 - The new "cairo" output driver supports output in PostScript, PDF,
150 and SVG formats. Its functionality is a superset of that of the
151 "postscript" driver, which has been removed. You must have Cairo
152 and Pango installed to build the "cairo" driver.
154 - Charts are now produced with Cairo and Pango, instead of libplot.
155 Without them, the new graphing features will not work. If you do
156 not have Cairo and Pango installed, you must run `configure' with
159 - The plain text output driver now properly supports multibyte UTF-8
160 characters, including double-width characters and combining
163 - Output to OpenDocument format is now supported.
165 - The HTML output is much improved.
167 * The "pspp" program has a new option --batch (or -b) that selects
168 "batch" syntax mode. In previous versions of PSPP this syntax mode
169 was the default. Now a new "auto" syntax mode is the default. In
170 "auto" mode, PSPP interprets most syntax files correctly regardless
171 of their intended syntax mode.
173 See the "Syntax Variants" section in the PSPP manual for more
176 * The "pspp" program has a new option --syntax-encoding that
177 specifies the encoding for syntax files listed on the command line,
178 as well as the default encoding for syntax files included with
179 INCLUDE or INSERT. The default is to accept the system locale
180 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
181 one the system file uses.
183 See the documentation for the INSERT command in the PSPP manual for
186 * Text data files that PRINT and WRITE creates now use the system
187 native line ends by default (CRLF on Windows, LF only elsewhere).
188 Use the new ENDS subcommand on FILE HANDLE to override the default.
190 * A new Perl module allows Perl programs to read and write PSPP
193 * A tutorial chapter has been added to the user manual.
195 Changes from 0.6.1 to 0.6.2:
199 - Dutch, thanks to Harry Thijssen.
201 - Brazilian Portuguese, thanks to Michel Boaventura.
203 Thanks for translations are also due to the coordinators at
204 translationproject.org.
206 * Statistical bug fixes:
208 - REGRESSION: Report correct standard error of the estimate (bug
211 - T-TEST: Report correct significance of paired sample T-test in
212 the common case (bug #26936) and corner cases. Thanks to Mike
213 Griffiths and Matej Cepl for reporting these bugs.
215 * Build fixes and changes:
217 - Fix build with GTK+ 2.17.4 and later.
219 - Make running "make" after running "configure" with different
220 settings reliably rebuild version.c.
222 - Cygwin and MinGW build fixes.
224 - Fixes for building with recent gnulib.
226 - The Makefile now honors two new variables, PSPP_LDFLAGS and
227 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
228 binaries, respectively. This makes building easier for some
231 - Fixes for "configure --enable-relocatable" (bug #25508).
233 * Data file bug fixes and changes:
235 - Fix reading text data files that contain a mix of white space
236 and commas. Now "a ,b" is treated as two fields containing "a"
237 and "b"; previously it was treated as three, with an empty field
240 - Fix writing corrupted .sav files on Windows.
242 - Fix writing variable labels longer than 252 bytes to save files.
243 Thanks to Robert Westlund for reporting this bug.
245 - Fix writing corrupted .por files (bug #26034).
247 - Fix reading .por files whose initial lines are not padded out
248 with spaces as expected.
250 - PSPP will no longer issue warnings about some .sav file records
251 or values that it does not understand. These warnings were
252 harmless, but needlessly alarmed some users.
254 - Fix crash reading empty string fields from PostgreSQL databases.
256 * Bug fixes that affect PSPP and PSPPIRE:
258 - Users may now control precision of output statistics. Instead
259 of hard coding the width and decimals of output numbers, respect
260 the default format in most instances. Counts are now normally
261 displayed with the format of the weight variable, if any.
263 - Fix crash when an INSERT command specifies the name of a file
264 that does not exist (bug #24569).
266 - Fix crash when CROSSTABS specifies a long-string variable (bugs
269 - Fix crash drawing pie charts with many segments.
271 - Fix crash when NUMERIC specifies an invalid format.
273 * PSPPIRE bug fixes and changes:
275 - On Windows, write the output file to the user's home directory
276 instead of the current directory, to better match user
279 - Some data editor fixes.
283 - Fix typo in BINOMIAL section of user manual (bug #25892).
285 Changes from 0.6.0 to 0.6.1:
287 * Statistical bug fixes:
289 - Report correct standardized regression coefficients in linear
290 regression output (bug #23567).
292 * Bug fixes that affect PSPP and PSPPIRE:
294 - Avoid crash with pie charts (bug #24014).
296 - Don't append % to count totals (bug #24003).
298 - Don't crash on bad input (bug #24031).
300 - Don't crash if "end data." is not left aligned (bug #24115).
302 - Change default workspace value to 64 MB, to avoid unnecessary
303 disk accesses on modern machines.
307 - Add ".sav" or ".por" suffix to filename when saving with Save_As
310 - Make it possible to reopen the output window on Windows (bug
313 - A POSIX regular expression library is now included and used
314 automatically if the host does not have one or has one that is
317 * Build fixes and changes:
319 - Work around bug in GSL that prevented build with recent GCC
320 versions without manually adding -fgnu89-inline to CFLAGS.
322 - Also warn about missing prerequisites as we encounter them (bug
325 - Distribute necessary files to allow users working from the
326 distributed tarball to configure with --enable-gui-tools.
328 - Append $(EXEEXT_FOR_BUILD) to output file name when building
329 q2c, fixing build problems on Windows.
331 - GSL 1.8 or later is now required.
333 - Build errors with --enable-relocatable were fixed.
335 * The German translations were removed, since native German speakers
336 found them too poor to be useful.
338 Changes from 0.4.0 to 0.6.0:
340 * The PSPP license is now version 3 or later of the GNU General
341 Public License. Previously, it was version 2 or later.
343 * PSPP now has a graphical interface, called PSPPIRE. This
344 interface allows you to enter data and variable definitions
345 interactively. Commands may be executed in syntax form, or by
346 using the interactive dialog boxes available from the dropdown
349 * A few sample syntax files are now included in the `examples'
352 * Numerous major and minor bugs have been fixed.
356 * The INSTALL file now reflects the details of how to install
357 PSPP. It is a tailored version of the generic installation
358 instructions, instead of a verbatim copy.
360 * iconv, which is ordinarily installed as part of a Unix-like
361 system, is now required. If you don't have it already, you can
362 install GNU libiconv (http://www.gnu.org/software/libiconv/).
364 * libxml2 and zlib are new optional dependencies. They are
365 required to use PSPP's support for reading Gnumeric files.
367 Statistical procedure changes:
369 * REGRESSION is a new procedure for fitting linear models to data
370 via least-squares estimation.
372 * NPAR TESTS is a new procedure for non-parametric tests. In this
373 release, it supports binomial and chi-square tests.
375 * RANK is a new procedure to rank variables. It supports numerous
378 * FREQUENCIES can now output histograms and pie charts. These
379 features were present in earlier releases, but not documented.
381 User interface changes:
383 * In many situations where PSPP once terminated with a fatal
384 error, PSPP now recovers and continues execution.
386 * PSPP is now able to start up and run even if it cannot find its
389 * Journaling of interactive commands to a disk file is now
390 implemented. By default, journaling is enabled, to a file named
391 `pspp.jnl' in the current directory. SET JOURNAL may be used to
394 * The use of `+' between syntax file names on the command line to
395 prevent the dictionary from being cleared between their
396 executions is no longer supported. All syntax files are now
397 executed as if `+' had been specified.
399 * The -d/--define and -u/--undef command line options are no
400 longer supported. Instead, use /usr/bin/env or shell primitives
401 to define or clear environment variables before invoking PSPP.
403 * If a syntax file named named `rc' is found in a configuration
404 directory (such as $HOME/.pspp), it is executed before any
405 syntax file specified on the command line. The -r or
406 --no-statrc command line option may be used to disable this
411 * Output configuration options have changed. Please refer to the
412 manual for a full description of the available options.
414 In consequence, you will need to reinstall your "devices" file.
415 "make install" will do this for you.
417 * Most error messages are now written to PSPP output files by
418 default. SET ERROR can be used to disable this behavior.
420 * When invoked interactively, PSPP now by default produces output
421 on the terminal, piping it through the "more" program.
422 Previously, by default output was written only to file
423 pspp.list. On most terminals, the page length used for output
424 automatically adapts to the terminal size, even if the terminal
429 - This driver now supports charts in output. Charts are written
430 as separate files that the main output file refers to. By
431 default, charts are written in PNG format to files named
432 pspp-1.png, pspp-2.png, and so on.
434 - Configurations are provided that use VT100 (and xterm)
435 line-drawing characters in tables. The option "-o list-vt100"
436 requests use of this device for output to pspp.list.
440 - The default paper size is now determined using the PAPERSIZE
441 environment variable, or the LC_PAPER locale category on
442 systems that support it. If these are not set, the default is
443 now A4, instead of US letter. To make US letter the default,
444 set PAPERSIZE to "letter" in your environment.
446 - Font metrics are now read from AFM files, instead of
447 Groff-format metrics files. PostScript fonts can now be
450 In consequence, you will need to install an AFM file for each
451 font used in PostScript output. "make install" will install
452 AFM files for the standard PostScript fonts, including the
453 ones that the PostScript driver uses by default.
455 - Standard paper sizes no longer need to be specified through a
456 configuration file. The "papersize" configuration file is no
457 longer needed, or supported.
459 - The PostScript prologue is no longer obtained from the
460 "ps-prologue" configuration file. This configuration file is
461 no longer needed, or supported.
465 - The HTML prologue is no longer obtained from the
466 "html-prologue" configuration file. This configuration file
467 is no longer needed, or supported.
469 Command language changes:
471 * The following commands are new:
473 - GET DATA, which currently supports reading Gnumeric files and
474 text data files. It will be extended later to read other
475 types of foreign data.
477 - CD, to change the current directory.
479 - INSERT, to execute a syntax file.
481 - DELETE VARIABLES, to remove variables from the active file
484 - ADD DOCUMENT, to add text to active file documents.
486 - CLOSE FILE HANDLE (a PSPP extension; see below).
488 - XEXPORT, a PSPP extension that is a transformation equivalent
491 * The following functions for transformation expressions are new:
493 - DATEDIFF, for computing the difference of two dates.
495 - DATESUM, for advancing a date by a specified duration.
497 - VALUELABEL, to obtain the value label for a value.
499 * PSPP now supports very long string variables (over 255 bytes
502 * MATCH FILES now supports the FIRST and LAST subcommands.
504 * Previous versions of PSPP prohibited using commands to both read and
505 write a single file at the same time. Now, PSPP allows this, and
506 the new version of the file atomically replaces the old version.
508 * The following commands are no longer available. They will be
509 re-implemented in a later release:
511 - CLEAR TRANSFORMATIONS
517 * The PROCESS IF command, which was deprecated, has been removed.
518 You may replace any usage of it by SELECT IF following
519 TEMPORARY, which has the same effect.
521 * The output format for variables created by VECTOR may now be
522 specified as part of the VECTOR syntax.
524 "Scratch files", a new PSPP extension:
526 A scratch file, like a system file, consists of a dictionary and
527 any number of cases. Small scratch files are stored in memory;
528 one that grows too large is written to disk. By default, any file
529 handle whose name begins with # is assumed to refer to a scratch
532 Scratch files can be used just about anywhere a system or portable
533 file can be used. Also, portable files are now allowed in most
534 places that system files were allowed in previous PSPP version.
536 A new CLOSE FILE HANDLE command allows the storage associated with
537 scratch files to be freed. It also allows file handles to be
538 reassigned to new files.
540 For more information on scratch files, refer to the "File Handles"
541 section in the PSPP manual. For specifics of what commands now
542 allow what kinds of files to be specified, refer to the
543 documentation on those particular commands.
547 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
548 translation, are now supported. Use FILE HANDLE to specify the
549 format of these files.
551 * Little-endian, big-endian, and VAX-endian formats are now
552 supported for integer binary formats when reading and writing
553 data files. The new RIB and WIB subcommands on the SET command
554 control endianness of integer data. The default is the host's
557 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
558 floating point binary formats when reading and writing data
559 files. The new RRB and WRB subcommands on the SET command
560 control the floating point format. The default is the host's
561 native floating point format.
563 * DATA LIST now supports the SKIP subcommand, to skip records at
564 the beginning of a file. For compatibility, DATA LIST now
565 treats N format as F format for FREE and LIST format input.
567 * The SAVE and XSAVE commands now support the UNSELECTED,
568 PERMISSIONS, NAMES, and MAP subcommands.
570 * The EXPORT command has been re-implemented to obtain better
571 results. Support for the UNSELECTED, DIGITS, and TYPE
572 subcommands has been added.
574 * For compatibility, PRINT now inserts a space at the beginning of
575 every output line, even lines that would otherwise be blank,
576 when OUTFILE is specified. (The behavior of WRITE is
579 * For compatibility, PRINT EJECT now inserts the digit `1' at the
580 beginning of each line that should begin a new page.
582 * For compatibility, WRITE now outputs the system-missing value as
583 a field filled with spaces. Binary formats are an exception.
584 (The behavior of PRINT is unchanged.)
588 * Input and output format descriptions have been rewritten. They
589 now precisely describe what is accepted on input and written on
592 * The descriptions of the PSPP system and portable file formats
593 have been extensively revised and improved.
595 For developers, the build system now requires Autoconf 2.60 and
598 Changes from 0.3.0 to 0.4.0:
600 Changes in build dependencies:
602 * The GNU Scientific Library (libgsl), version 1.6 or later, is
605 * libplot from GNU plotutils is optional. Without it, the new
606 graphing features will not work. If you do not have it
607 installed, you must run `configure' with --without-libplot.
609 * libgmp2 is no longer a dependency.
611 Newly implemented commands and statistical features:
613 * EXAMINE, including its graphing features.
615 * FREQUENCIES now supports percentiles.
623 * SORT CASES now sorts stably, that is, two cases with equal sort
624 criteria will be in the same relative order before and after the
627 * T-TEST (re-written).
629 * DATE and USE. These commands are parsed but otherwise ignored,
630 to enhance compatibility with certain command files that invoke
633 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
634 currently have no effect on PSPP output, but their values are
635 written to and read from system files and thus may affect
636 third-party software.
638 * SET EPOCH implemented.
640 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
643 * FILE HANDLE now supports custom tab widths.
645 Long variable names (and other identifiers) are now supported. Up
646 to the first 64 bytes of each identifier is significant. PSPP now
647 reads and writes system files compatible with SPSS version 12.
649 New --algorithm and --syntax command line options allow
650 SPSS-compatible or enhanced modes to be selected.
652 Support for transformation expressions has been rewritten and
653 significantly improved. Refer to the manual for details.
655 Calculation of moments (mean, standard deviation, kurtosis,
656 skewness) has been rewritten and should now be more accurate. In
657 --algorithm=enhanced mode moments may be more accurate than SPSS in
660 Numerous bugs have been fixed, too many to mention here. Many new
661 tests have been added, leading to the discovery and fixing of many
664 The ASCII output driver can now squeeze multiple blank lines into
667 Much of the code has been rewritten and refactored. It is now much
670 The FILE TYPE and REPEATING DATA commands have been disabled for
671 this release because their implementations were deemed too buggy to
672 be useful. They will be fixed and replaced in a future release.
674 New pspp-mode for Emacs (in pspp-mode.el).
676 Added rudimentary command-line completion for interactive input.
678 lib/julcal and lib/dcdflib are no longer used, so they have been
681 For developers, the build system now requires Autoconf 2.58 and
682 Automake 1.7. The included gettext has been updated to version
685 Some reports state that Texinfo 4.8, the latest version, may be
686 necessary to successfully format the documentation on some systems.
688 Version 0.3.0 changes since 0.2.3:
692 * Using alphanumeric variables in functions under AGGREGATE
695 * Under certain circumstances, the final case would be omitted
696 from the results of an AGGREGATE operation. Fixed.
698 * Undefined behavior was invoked by referencing a freed pointer
699 under certain circumstances. Fixed.
701 * A wrong record size was displayed when paging the active file to
704 * Not having enough temporary space for sorting caused a core
707 * Syntax errors in function descriptions on AGGREGATE caused core
710 * A null pointer was dereferenced, causing a core dump, when
711 PERCENTILES was specified on FREQUENCIES. This fixes the
712 problem, but PSPP still doesn't calculate percentiles.
714 * SORT always sorted in ascending order. Fixed.
716 * Some minor memory leaks in the expression parser were removed.
718 * Many assertions fixed for strict ANSI C compliance.
722 * SET ECHO ON now implemented, but turned off by default.
724 * PRINT specifier supported on END REPEAT.
728 * System libgmp2 library is used if installed instead of
729 unconditionally using the included libgmp2 subset.
731 * Extensive code cleanup, which continues.
733 * Added CORRELATIONS command parser, but not implemented.
735 Version 0.2.3 changes since 0.2.2:
739 * SPLIT FILE with a string variable caused a core dump. Fixed.
741 * Nested INCLUDEs didn't work. Fixed.
743 * The MATCH FILES procedure set the values of variables not present
744 to 0. It should have been SYSMIS. This is now fixed.
746 * The REMARK command was too aggressive about skipping lines. It
747 didn't like being the last command in a file.
749 * Comment parsing wasn't consistent with the rest of the code in its
750 idea of where one command ends and another starts. This meant
751 that sometimes commands would be mysteriously ignored. Thanks to
752 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
754 * The TABLE subcommand on MATCH FILES worked only erratically at
755 best. This fixes it. Thanks to Dr. Dirk Melcher
756 <BZN-mdksh@t-online.de> for reporting this bug.
758 * VARIABLE LABELS rejected a slash before the first variable
759 specification, contradicting the documentation. Thanks to Walter
760 M. Gray <graywm@northernc.on.ca> for reporting this bug.
762 * Because of an incorrect optimization in memory allocation,
763 CROSSTABS sometimes segfaulted when asked to output multiple
764 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
767 * CROSSTABS didn't display value labels for column and row
768 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
771 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
772 <BZN-mdksh@t-online.de> for reporting this bug.
774 * The TABLE subcommand on MATCH FILES worked only erratically at
775 best. This fixes it. Thanks to Dr. Dirk Melcher
776 <BZN-mdksh@t-online.de> for reporting this bug.
778 * VARIABLE LABELS rejected a slash before the first variable
779 specification, contradicting the documentation. Thanks to Walter
780 M. Gray <graywm@northernc.on.ca> for reporting this bug.
782 * Because of an incorrect optimization in memory allocation,
783 CROSSTABS sometimes segfaulted when asked to output multiple
784 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
787 * CROSSTABS didn't display value labels for column and row
788 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
791 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
792 <BZN-mdksh@t-online.de> for reporting this bug.
794 * MATCH FILES corrupted memory and dumped core on some syntax
797 * MATCH FILES should set numeric values not available to the
798 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
799 <BZN-mdksh@t-online.de> for reporting this bug.
801 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
802 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
