5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
7 Changes from 0.7.3 to 0.7.7:
9 * The QUICK CLUSTER command is now implemented.
11 * The "pspp" program has a new option --batch (or -b) that selects
12 "batch" syntax mode. In previous versions of PSPP this syntax mode
13 was the default. Now a new "auto" syntax mode is the default. In
14 "auto" mode, PSPP interprets most syntax files correctly regardless
15 of their intended syntax mode.
17 See the "Syntax Variants" section in the PSPP manual for more
20 * The "pspp" program has a new option --syntax-encoding that
21 specifies the encoding for syntax files listed on the command line,
22 as well as the default encoding for syntax files included with
23 INCLUDE or INSERT. The default is to accept the system locale
24 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
25 one the system file uses.
27 See the documentation for the INSERT command in the PSPP manual for
30 * The INCLUDE and INSERT commands now support the ENCODING subcommand
31 to specify the encoding for the included syntax file.
33 * The plain text output driver now properly supports multibyte UTF-8
34 characters, including double-width characters and combining
37 * Strings may now include arbitrary Unicode code points specified in
38 hexadecimal, using the syntax U'hhhh'. For example, Unicode code
39 point U+1D11E, the musical G clef character, may be expressed as
42 See the "Tokens" section in the PSPP manual for more information.
44 * In previous versions of PSPP, in a string expressed in hexadecimal
45 with X'hh' syntax, the hexadecimal digits expressed bytes in the
46 locale encoding. In this version of PSPP, X'hh' syntax always
47 expresses bytes in UTF-8 encoding.
49 See the "Tokens" section in the PSPP manual for more information.
51 * The DO REPEAT command has been reimplemented. The most prominent
52 change is that when a DO REPEAT block contains an INCLUDE or INSERT
53 command, substitutions are not applied to the included file.
55 See the "DO REPEAT" section in the PSPP manual for more information.
57 * NPAR TESTS now supports the /KRUSKAL-WALLIS and /RUNS subcommands.
59 * AUTORECODE now supports the /GROUP subcommand.
61 * The MRSETS command is now implemented.
63 * SAVE TRANSLATE is now implemented, with initial support for saving
64 data in comma-separated value and tab-delimited formats.
66 * The PRESERVE and RESTORE commands are now implemented.
68 * The HOST command has been updated to use more modern syntax.
70 * The SET and SHOW commands no longer support the ENDCMD, NULLINE,
71 PROMPT, CPROMPT, and DPROMPT subcommands. The defaults are now the
72 only supported values.
74 * The dataset commands DATASET ACTIVATE, DATASET DECLARE, DATASET
75 CLOSE, DATASET COPY, DATASET NAME, DATASET DISPLAY are now
76 implemented. These commands replace the "scratch file" PSPP
77 extension, which is no longer supported.
79 Changes from 0.7.2 to 0.7.3:
81 * Charts are now produced with Cairo and Pango, instead of libplot.
82 Without them, the new graphing features will not work. If you do
83 not have Cairo and Pango installed, you must run `configure' with
86 * The new "cairo" output driver supports output in PostScript, PDF,
87 and SVG formats. Its functionality is a superset of that of the
88 "postscript" driver, which has been removed. You must have Cairo
89 and Pango installed to build the "cairo" driver.
91 Changes from 0.7.1 to 0.7.2:
93 * Updated Perl module interface.
95 * Value labels for long string variables are now supported.
97 * Missing values for long string variables are now supported.
99 Changes from 0.7.0 to 0.7.1:
101 * Added a perl module to facilitate reading and writing of pspp system
102 files from perl programs.
104 Changes from 0.6.2-pre6 to 0.7.0:
106 * Custom variable and data file attributes are now supported.
107 Commands VARIABLE ATTRIBUTE and DATAFILE ATTRIBUTE have been added
108 for setting and clear attributes. Support for attributes has also
109 been added to commands that read and write system files, such as
110 SAVE and GET, as well as to the DISPLAY command.
112 * Numererous improvements to the Graphical User Interface have
113 made. Notable improvements include:
115 - Non-Ascii characters in strings, labels and variable names are
118 - A "Split Window" function is available, which makes it easier to
119 see different parts of a large data file.
121 - Data files can now be opened by specifing their name as the first
122 argument. This means that on a properly configured desktop, double
123 clicking on an icon will open the file.
126 * New statistical procedures:
131 NPAR TESTS now supports the WILCOXON and SIGN subcommands.
133 The CROSSTABS command has been completely re-implemented to fix numerous bugs.
135 * Three new commands to combine data files have been added: MATCH FILES,
136 UPDATE and ADD FILES.
138 * A tutorial chapter has been added to the user manual.
140 Changes from 0.6.1 to 0.6.2
144 - Dutch, thanks to Harry Thijssen.
146 - Brazilian Portuguese, thanks to Michel Boaventura.
148 Thanks for translations are also due to the coordinators at
149 translationproject.org.
151 * Statistical bug fixes:
153 - REGRESSION: Report correct standard error of the estimate (bug
156 - T-TEST: Report correct significance of paired sample T-test in
157 the common case (bug #26936) and corner cases. Thanks to Mike
158 Griffiths and Matej Cepl for reporting these bugs.
160 * Build fixes and changes:
162 - Fix build with GTK+ 2.17.4 and later.
164 - Make running "make" after running "configure" with different
165 settings reliably rebuild version.c.
167 - Cygwin and MinGW build fixes.
169 - Fixes for building with recent gnulib.
171 - The Makefile now honors two new variables, PSPP_LDFLAGS and
172 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
173 binaries, respectively. This makes building easier for some
176 - Fixes for "configure --enable-relocatable" (bug #25508).
178 * Data file bug fixes and changes:
180 - Fix reading text data files that contain a mix of white space
181 and commas. Now "a ,b" is treated as two fields containing "a"
182 and "b"; previously it was treated as three, with an empty field
185 - Fix writing corrupted .sav files on Windows.
187 - Fix writing variable labels longer than 252 bytes to save files.
188 Thanks to Robert Westlund for reporting this bug.
190 - Fix writing corrupted .por files (bug #26034).
192 - Fix reading .por files whose initial lines are not padded out
193 with spaces as expected.
195 - PSPP will no longer issue warnings about some .sav file records
196 or values that it does not understand. These warnings were
197 harmless, but needlessly alarmed some users.
199 - Fix crash reading empty string fields from PostgreSQL databases.
201 * Bug fixes that affect PSPP and PSPPIRE:
203 - Users may now control precision of output statistics. Instead
204 of hard coding the width and decimals of output numbers, respect
205 the default format in most instances. Counts are now normally
206 displayed with the format of the weight variable, if any.
208 - Fix crash when an INSERT command specifies the name of a file
209 that does not exist (bug #24569).
211 - Fix crash when CROSSTABS specifies a long-string variable (bugs
214 - Fix crash drawing pie charts with many segments.
216 - Fix crash when NUMERIC specifies an invalid format.
218 * PSPPIRE bug fixes and changes:
220 - On Windows, write the output file to the user's home directory
221 instead of the current directory, to better match user
224 - Some data editor fixes.
228 - Fix typo in BINOMIAL section of user manual (bug #25892).
230 Changes from 0.6.0 to 0.6.1:
232 * Statistical bug fixes:
234 - Report correct standardized regression coefficients in linear
235 regression output (bug #23567).
237 * Bug fixes that affect PSPP and PSPPIRE:
239 - Avoid crash with pie charts (bug #24014).
241 - Don't append % to count totals (bug #24003).
243 - Don't crash on bad input (bug #24031).
245 - Don't crash if "end data." is not left aligned (bug #24115).
247 - Change default workspace value to 64 MB, to avoid unnecessary
248 disk accesses on modern machines.
252 - Add ".sav" or ".por" suffix to filename when saving with Save_As
255 - Make it possible to reopen the output window on Windows (bug
258 - A POSIX regular expression library is now included and used
259 automatically if the host does not have one or has one that is
262 * Build fixes and changes:
264 - Work around bug in GSL that prevented build with recent GCC
265 versions without manually adding -fgnu89-inline to CFLAGS.
267 - Also warn about missing prerequisites as we encounter them (bug
270 - Distribute necessary files to allow users working from the
271 distributed tarball to configure with --enable-gui-tools.
273 - Append $(EXEEXT_FOR_BUILD) to output file name when building
274 q2c, fixing build problems on Windows.
276 - GSL 1.8 or later is now required.
278 - Build errors with --enable-relocatable were fixed.
280 * The German translations were removed, since native German speakers
281 found them too poor to be useful.
283 Changes from 0.4.0 to 0.6.0:
285 * The PSPP license is now version 3 or later of the GNU General
286 Public License. Previously, it was version 2 or later.
288 * PSPP now has a graphical interface, called PSPPIRE. This
289 interface allows you to enter data and variable definitions
290 interactively. Commands may be executed in syntax form, or by
291 using the interactive dialog boxes available from the dropdown
294 * A few sample syntax files are now included in the `examples'
297 * Numerous major and minor bugs have been fixed.
301 * The INSTALL file now reflects the details of how to install
302 PSPP. It is a tailored version of the generic installation
303 instructions, instead of a verbatim copy.
305 * iconv, which is ordinarily installed as part of a Unix-like
306 system, is now required. If you don't have it already, you can
307 install GNU libiconv (http://www.gnu.org/software/libiconv/).
309 * libxml2 and zlib are new optional dependencies. They are
310 required to use PSPP's support for reading Gnumeric files.
312 Statistical procedure changes:
314 * REGRESSION is a new procedure for fitting linear models to data
315 via least-squares estimation.
317 * NPAR TESTS is a new procedure for non-parametric tests. In this
318 release, it supports binomial and chi-square tests.
320 * RANK is a new procedure to rank variables. It supports numerous
323 * FREQUENCIES can now output histograms and pie charts. These
324 features were present in earlier releases, but not documented.
326 User interface changes:
328 * In many situations where PSPP once terminated with a fatal
329 error, PSPP now recovers and continues execution.
331 * PSPP is now able to start up and run even if it cannot find its
334 * Journaling of interactive commands to a disk file is now
335 implemented. By default, journaling is enabled, to a file named
336 `pspp.jnl' in the current directory. SET JOURNAL may be used to
339 * The use of `+' between syntax file names on the command line to
340 prevent the dictionary from being cleared between their
341 executions is no longer supported. All syntax files are now
342 executed as if `+' had been specified.
344 * The -d/--define and -u/--undef command line options are no
345 longer supported. Instead, use /usr/bin/env or shell primitives
346 to define or clear environment variables before invoking PSPP.
348 * If a syntax file named named `rc' is found in a configuration
349 directory (such as $HOME/.pspp), it is executed before any
350 syntax file specified on the command line. The -r or
351 --no-statrc command line option may be used to disable this
356 * Output configuration options have changed. Please refer to the
357 manual for a full description of the available options.
359 In consequence, you will need to reinstall your "devices" file.
360 "make install" will do this for you.
362 * Most error messages are now written to PSPP output files by
363 default. SET ERROR can be used to disable this behavior.
365 * When invoked interactively, PSPP now by default produces output
366 on the terminal, piping it through the "more" program.
367 Previously, by default output was written only to file
368 pspp.list. On most terminals, the page length used for output
369 automatically adapts to the terminal size, even if the terminal
374 - This driver now supports charts in output. Charts are written
375 as separate files that the main output file refers to. By
376 default, charts are written in PNG format to files named
377 pspp-1.png, pspp-2.png, and so on.
379 - Configurations are provided that use VT100 (and xterm)
380 line-drawing characters in tables. The option "-o list-vt100"
381 requests use of this device for output to pspp.list.
385 - The default paper size is now determined using the PAPERSIZE
386 environment variable, or the LC_PAPER locale category on
387 systems that support it. If these are not set, the default is
388 now A4, instead of US letter. To make US letter the default,
389 set PAPERSIZE to "letter" in your environment.
391 - Font metrics are now read from AFM files, instead of
392 Groff-format metrics files. PostScript fonts can now be
395 In consequence, you will need to install an AFM file for each
396 font used in PostScript output. "make install" will install
397 AFM files for the standard PostScript fonts, including the
398 ones that the PostScript driver uses by default.
400 - Standard paper sizes no longer need to be specified through a
401 configuration file. The "papersize" configuration file is no
402 longer needed, or supported.
404 - The PostScript prologue is no longer obtained from the
405 "ps-prologue" configuration file. This configuration file is
406 no longer needed, or supported.
410 - The HTML prologue is no longer obtained from the
411 "html-prologue" configuration file. This configuration file
412 is no longer needed, or supported.
414 Command language changes:
416 * The following commands are new:
418 - GET DATA, which currently supports reading Gnumeric files and
419 text data files. It will be extended later to read other
420 types of foreign data.
422 - CD, to change the current directory.
424 - INSERT, to execute a syntax file.
426 - DELETE VARIABLES, to remove variables from the active file
429 - ADD DOCUMENT, to add text to active file documents.
431 - CLOSE FILE HANDLE (a PSPP extension; see below).
433 - XEXPORT, a PSPP extension that is a transformation equivalent
436 * The following functions for transformation expressions are new:
438 - DATEDIFF, for computing the difference of two dates.
440 - DATESUM, for advancing a date by a specified duration.
442 - VALUELABEL, to obtain the value label for a value.
444 * PSPP now supports very long string variables (over 255 bytes
447 * MATCH FILES now supports the FIRST and LAST subcommands.
449 * Previous versions of PSPP prohibited using commands to both read and
450 write a single file at the same time. Now, PSPP allows this, and
451 the new version of the file atomically replaces the old version.
453 * The following commands are no longer available. They will be
454 re-implemented in a later release:
456 - CLEAR TRANSFORMATIONS
462 * The PROCESS IF command, which was deprecated, has been removed.
463 You may replace any usage of it by SELECT IF following
464 TEMPORARY, which has the same effect.
466 * The output format for variables created by VECTOR may now be
467 specified as part of the VECTOR syntax.
469 "Scratch files", a new PSPP extension:
471 A scratch file, like a system file, consists of a dictionary and
472 any number of cases. Small scratch files are stored in memory;
473 one that grows too large is written to disk. By default, any file
474 handle whose name begins with # is assumed to refer to a scratch
477 Scratch files can be used just about anywhere a system or portable
478 file can be used. Also, portable files are now allowed in most
479 places that system files were allowed in previous PSPP version.
481 A new CLOSE FILE HANDLE command allows the storage associated with
482 scratch files to be freed. It also allows file handles to be
483 reassigned to new files.
485 For more information on scratch files, refer to the "File Handles"
486 section in the PSPP manual. For specifics of what commands now
487 allow what kinds of files to be specified, refer to the
488 documentation on those particular commands.
492 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
493 translation, are now supported. Use FILE HANDLE to specify the
494 format of these files.
496 * Little-endian, big-endian, and VAX-endian formats are now
497 supported for integer binary formats when reading and writing
498 data files. The new RIB and WIB subcommands on the SET command
499 control endianness of integer data. The default is the host's
502 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
503 floating point binary formats when reading and writing data
504 files. The new RRB and WRB subcommands on the SET command
505 control the floating point format. The default is the host's
506 native floating point format.
508 * DATA LIST now supports the SKIP subcommand, to skip records at
509 the beginning of a file. For compatibility, DATA LIST now
510 treats N format as F format for FREE and LIST format input.
512 * The SAVE and XSAVE commands now support the UNSELECTED,
513 PERMISSIONS, NAMES, and MAP subcommands.
515 * The EXPORT command has been re-implemented to obtain better
516 results. Support for the UNSELECTED, DIGITS, and TYPE
517 subcommands has been added.
519 * For compatibility, PRINT now inserts a space at the beginning of
520 every output line, even lines that would otherwise be blank,
521 when OUTFILE is specified. (The behavior of WRITE is
524 * For compatibility, PRINT EJECT now inserts the digit `1' at the
525 beginning of each line that should begin a new page.
527 * For compatibility, WRITE now outputs the system-missing value as
528 a field filled with spaces. Binary formats are an exception.
529 (The behavior of PRINT is unchanged.)
533 * Input and output format descriptions have been rewritten. They
534 now precisely describe what is accepted on input and written on
537 * The descriptions of the PSPP system and portable file formats
538 have been extensively revised and improved.
540 For developers, the build system now requires Autoconf 2.60 and
543 Changes from 0.3.0 to 0.4.0:
545 Changes in build dependencies:
547 * The GNU Scientific Library (libgsl), version 1.6 or later, is
550 * libplot from GNU plotutils is optional. Without it, the new
551 graphing features will not work. If you do not have it
552 installed, you must run `configure' with --without-libplot.
554 * libgmp2 is no longer a dependency.
556 Newly implemented commands and statistical features:
558 * EXAMINE, including its graphing features.
560 * FREQUENCIES now supports percentiles.
568 * SORT CASES now sorts stably, that is, two cases with equal sort
569 criteria will be in the same relative order before and after the
572 * T-TEST (re-written).
574 * DATE and USE. These commands are parsed but otherwise ignored,
575 to enhance compatibility with certain command files that invoke
578 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
579 currently have no effect on PSPP output, but their values are
580 written to and read from system files and thus may affect
581 third-party software.
583 * SET EPOCH implemented.
585 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
588 * FILE HANDLE now supports custom tab widths.
590 Long variable names (and other identifiers) are now supported. Up
591 to the first 64 bytes of each identifier is significant. PSPP now
592 reads and writes system files compatible with SPSS version 12.
594 New --algorithm and --syntax command line options allow
595 SPSS-compatible or enhanced modes to be selected.
597 Support for transformation expressions has been rewritten and
598 significantly improved. Refer to the manual for details.
600 Calculation of moments (mean, standard deviation, kurtosis,
601 skewness) has been rewritten and should now be more accurate. In
602 --algorithm=enhanced mode moments may be more accurate than SPSS in
605 Numerous bugs have been fixed, too many to mention here. Many new
606 tests have been added, leading to the discovery and fixing of many
609 The ASCII output driver can now squeeze multiple blank lines into
612 Much of the code has been rewritten and refactored. It is now much
615 The FILE TYPE and REPEATING DATA commands have been disabled for
616 this release because their implementations were deemed too buggy to
617 be useful. They will be fixed and replaced in a future release.
619 New pspp-mode for Emacs (in pspp-mode.el).
621 Added rudimentary command-line completion for interactive input.
623 lib/julcal and lib/dcdflib are no longer used, so they have been
626 For developers, the build system now requires Autoconf 2.58 and
627 Automake 1.7. The included gettext has been updated to version
630 Some reports state that Texinfo 4.8, the latest version, may be
631 necessary to successfully format the documentation on some systems.
633 Version 0.3.0 changes since 0.2.3:
637 * Using alphanumeric variables in functions under AGGREGATE
640 * Under certain circumstances, the final case would be omitted
641 from the results of an AGGREGATE operation. Fixed.
643 * Undefined behavior was invoked by referencing a freed pointer
644 under certain circumstances. Fixed.
646 * A wrong record size was displayed when paging the active file to
649 * Not having enough temporary space for sorting caused a core
652 * Syntax errors in function descriptions on AGGREGATE caused core
655 * A null pointer was dereferenced, causing a core dump, when
656 PERCENTILES was specified on FREQUENCIES. This fixes the
657 problem, but PSPP still doesn't calculate percentiles.
659 * SORT always sorted in ascending order. Fixed.
661 * Some minor memory leaks in the expression parser were removed.
663 * Many assertions fixed for strict ANSI C compliance.
667 * SET ECHO ON now implemented, but turned off by default.
669 * PRINT specifier supported on END REPEAT.
673 * System libgmp2 library is used if installed instead of
674 unconditionally using the included libgmp2 subset.
676 * Extensive code cleanup, which continues.
678 * Added CORRELATIONS command parser, but not implemented.
680 Version 0.2.3 changes since 0.2.2:
684 * SPLIT FILE with a string variable caused a core dump. Fixed.
686 * Nested INCLUDEs didn't work. Fixed.
688 * The MATCH FILES procedure set the values of variables not present
689 to 0. It should have been SYSMIS. This is now fixed.
691 * The REMARK command was too aggressive about skipping lines. It
692 didn't like being the last command in a file.
694 * Comment parsing wasn't consistent with the rest of the code in its
695 idea of where one command ends and another starts. This meant
696 that sometimes commands would be mysteriously ignored. Thanks to
697 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
699 * The TABLE subcommand on MATCH FILES worked only erratically at
700 best. This fixes it. Thanks to Dr. Dirk Melcher
701 <BZN-mdksh@t-online.de> for reporting this bug.
703 * VARIABLE LABELS rejected a slash before the first variable
704 specification, contradicting the documentation. Thanks to Walter
705 M. Gray <graywm@northernc.on.ca> for reporting this bug.
707 * Because of an incorrect optimization in memory allocation,
708 CROSSTABS sometimes segfaulted when asked to output multiple
709 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
712 * CROSSTABS didn't display value labels for column and row
713 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
716 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
717 <BZN-mdksh@t-online.de> for reporting this bug.
719 * The TABLE subcommand on MATCH FILES worked only erratically at
720 best. This fixes it. Thanks to Dr. Dirk Melcher
721 <BZN-mdksh@t-online.de> for reporting this bug.
723 * VARIABLE LABELS rejected a slash before the first variable
724 specification, contradicting the documentation. Thanks to Walter
725 M. Gray <graywm@northernc.on.ca> for reporting this bug.
727 * Because of an incorrect optimization in memory allocation,
728 CROSSTABS sometimes segfaulted when asked to output multiple
729 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
732 * CROSSTABS didn't display value labels for column and row
733 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
736 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
737 <BZN-mdksh@t-online.de> for reporting this bug.
739 * MATCH FILES corrupted memory and dumped core on some syntax
742 * MATCH FILES should set numeric values not available to the
743 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
744 <BZN-mdksh@t-online.de> for reporting this bug.
746 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
747 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
751 * Some systems didn't like the way open_file was coded. Thanks to
752 Hankin <hankin@rogue.consultco.com> for pointing this out.
754 * The SAVE procedure didn't save long string variables properly.
755 Fixed by this patch. Thanks to Hankin
756 <hankin@rogue.consultco.com> for this patch.
758 * Minor documentation fixes for MATCH FILES.
760 Version 0.2.2 changes since 0.2.1:
764 * Fix behavior of PRINT SPACE for negative arguments.
766 * Fix reading some unusual system files.
768 * Fix LIST problems with very long variables. Thanks to Hankin
769 <hankin@dunno.com> for this bug report.
771 * Fix problems with some string format specifiers.
773 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
