7 Changes from 0.6.2 to 0.7.8:
22 - PRESERVE and RESTORE
26 - SAVE TRANSLATE to CSV and tab-delimited files
30 * Changes to existing commands:
32 - AUTORECODE has a new GROUP subcommand.
34 - CROSSTABS has been re-implemented to fix numerous bugs.
36 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
37 contains an INCLUDE or INSERT command, substitutions are not
38 applied to the included file.
40 - HOST has been updated to use more modern syntax.
42 - INCLUDE and INSERT have a new ENCODING subcommand.
44 - MISSING VALUES can now assign missing values to long string
47 - ONEWAY: the POSTHOC subcommand is now implemented.
49 - The following new subcommands to NPAR TESTS have been implemented:
50 COCHRAN, FRIEDMAN, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY, MCNEMAR,
51 SIGN, WILCOXON, and RUNS
53 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
54 DPROMPT subcommands. The defaults are now fixed values.
56 - VALUE LABELS can now assign value labels to long string
59 * Other language changes:
61 - The new DATASET commands replace the "scratch file" PSPP
62 extension, which is no longer supported.
64 - Strings may now include arbitrary Unicode code points specified
65 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
66 code point U+1D11E, the musical G clef character, may be
67 expressed as U'1D11E'.
69 See the "Tokens" section in the PSPP manual for more information.
71 - In previous versions of PSPP, in a string expressed in
72 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
73 bytes in the locale encoding. In this version of PSPP, X'hh'
74 syntax always expresses bytes in UTF-8 encoding.
76 See the "Tokens" section in the PSPP manual for more information.
78 * PSPPIRE graphical user interface improvements:
80 - Added support for non-ASCII characters in strings, labels and
83 - A "Split Window" function is available, which makes it easier to
84 see different parts of a large data file.
86 - Data files can now be opened by specifing their name as the first
87 argument. This means that on a properly configured desktop, double
88 clicking on an icon will open the file.
92 - The new "cairo" output driver supports output in PostScript, PDF,
93 and SVG formats. Its functionality is a superset of that of the
94 "postscript" driver, which has been removed. You must have Cairo
95 and Pango installed to build the "cairo" driver.
97 - Charts are now produced with Cairo and Pango, instead of libplot.
98 Without them, the new graphing features will not work. If you do
99 not have Cairo and Pango installed, you must run `configure' with
102 - The plain text output driver now properly supports multibyte UTF-8
103 characters, including double-width characters and combining
106 * The "pspp" program has a new option --batch (or -b) that selects
107 "batch" syntax mode. In previous versions of PSPP this syntax mode
108 was the default. Now a new "auto" syntax mode is the default. In
109 "auto" mode, PSPP interprets most syntax files correctly regardless
110 of their intended syntax mode.
112 See the "Syntax Variants" section in the PSPP manual for more
115 * The "pspp" program has a new option --syntax-encoding that
116 specifies the encoding for syntax files listed on the command line,
117 as well as the default encoding for syntax files included with
118 INCLUDE or INSERT. The default is to accept the system locale
119 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
120 one the system file uses.
122 See the documentation for the INSERT command in the PSPP manual for
125 * A new Perl module allows Perl programs to read and write PSPP
128 * A tutorial chapter has been added to the user manual.
130 Changes from 0.6.1 to 0.6.2:
134 - Dutch, thanks to Harry Thijssen.
136 - Brazilian Portuguese, thanks to Michel Boaventura.
138 Thanks for translations are also due to the coordinators at
139 translationproject.org.
141 * Statistical bug fixes:
143 - REGRESSION: Report correct standard error of the estimate (bug
146 - T-TEST: Report correct significance of paired sample T-test in
147 the common case (bug #26936) and corner cases. Thanks to Mike
148 Griffiths and Matej Cepl for reporting these bugs.
150 * Build fixes and changes:
152 - Fix build with GTK+ 2.17.4 and later.
154 - Make running "make" after running "configure" with different
155 settings reliably rebuild version.c.
157 - Cygwin and MinGW build fixes.
159 - Fixes for building with recent gnulib.
161 - The Makefile now honors two new variables, PSPP_LDFLAGS and
162 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
163 binaries, respectively. This makes building easier for some
166 - Fixes for "configure --enable-relocatable" (bug #25508).
168 * Data file bug fixes and changes:
170 - Fix reading text data files that contain a mix of white space
171 and commas. Now "a ,b" is treated as two fields containing "a"
172 and "b"; previously it was treated as three, with an empty field
175 - Fix writing corrupted .sav files on Windows.
177 - Fix writing variable labels longer than 252 bytes to save files.
178 Thanks to Robert Westlund for reporting this bug.
180 - Fix writing corrupted .por files (bug #26034).
182 - Fix reading .por files whose initial lines are not padded out
183 with spaces as expected.
185 - PSPP will no longer issue warnings about some .sav file records
186 or values that it does not understand. These warnings were
187 harmless, but needlessly alarmed some users.
189 - Fix crash reading empty string fields from PostgreSQL databases.
191 * Bug fixes that affect PSPP and PSPPIRE:
193 - Users may now control precision of output statistics. Instead
194 of hard coding the width and decimals of output numbers, respect
195 the default format in most instances. Counts are now normally
196 displayed with the format of the weight variable, if any.
198 - Fix crash when an INSERT command specifies the name of a file
199 that does not exist (bug #24569).
201 - Fix crash when CROSSTABS specifies a long-string variable (bugs
204 - Fix crash drawing pie charts with many segments.
206 - Fix crash when NUMERIC specifies an invalid format.
208 * PSPPIRE bug fixes and changes:
210 - On Windows, write the output file to the user's home directory
211 instead of the current directory, to better match user
214 - Some data editor fixes.
218 - Fix typo in BINOMIAL section of user manual (bug #25892).
220 Changes from 0.6.0 to 0.6.1:
222 * Statistical bug fixes:
224 - Report correct standardized regression coefficients in linear
225 regression output (bug #23567).
227 * Bug fixes that affect PSPP and PSPPIRE:
229 - Avoid crash with pie charts (bug #24014).
231 - Don't append % to count totals (bug #24003).
233 - Don't crash on bad input (bug #24031).
235 - Don't crash if "end data." is not left aligned (bug #24115).
237 - Change default workspace value to 64 MB, to avoid unnecessary
238 disk accesses on modern machines.
242 - Add ".sav" or ".por" suffix to filename when saving with Save_As
245 - Make it possible to reopen the output window on Windows (bug
248 - A POSIX regular expression library is now included and used
249 automatically if the host does not have one or has one that is
252 * Build fixes and changes:
254 - Work around bug in GSL that prevented build with recent GCC
255 versions without manually adding -fgnu89-inline to CFLAGS.
257 - Also warn about missing prerequisites as we encounter them (bug
260 - Distribute necessary files to allow users working from the
261 distributed tarball to configure with --enable-gui-tools.
263 - Append $(EXEEXT_FOR_BUILD) to output file name when building
264 q2c, fixing build problems on Windows.
266 - GSL 1.8 or later is now required.
268 - Build errors with --enable-relocatable were fixed.
270 * The German translations were removed, since native German speakers
271 found them too poor to be useful.
273 Changes from 0.4.0 to 0.6.0:
275 * The PSPP license is now version 3 or later of the GNU General
276 Public License. Previously, it was version 2 or later.
278 * PSPP now has a graphical interface, called PSPPIRE. This
279 interface allows you to enter data and variable definitions
280 interactively. Commands may be executed in syntax form, or by
281 using the interactive dialog boxes available from the dropdown
284 * A few sample syntax files are now included in the `examples'
287 * Numerous major and minor bugs have been fixed.
291 * The INSTALL file now reflects the details of how to install
292 PSPP. It is a tailored version of the generic installation
293 instructions, instead of a verbatim copy.
295 * iconv, which is ordinarily installed as part of a Unix-like
296 system, is now required. If you don't have it already, you can
297 install GNU libiconv (http://www.gnu.org/software/libiconv/).
299 * libxml2 and zlib are new optional dependencies. They are
300 required to use PSPP's support for reading Gnumeric files.
302 Statistical procedure changes:
304 * REGRESSION is a new procedure for fitting linear models to data
305 via least-squares estimation.
307 * NPAR TESTS is a new procedure for non-parametric tests. In this
308 release, it supports binomial and chi-square tests.
310 * RANK is a new procedure to rank variables. It supports numerous
313 * FREQUENCIES can now output histograms and pie charts. These
314 features were present in earlier releases, but not documented.
316 User interface changes:
318 * In many situations where PSPP once terminated with a fatal
319 error, PSPP now recovers and continues execution.
321 * PSPP is now able to start up and run even if it cannot find its
324 * Journaling of interactive commands to a disk file is now
325 implemented. By default, journaling is enabled, to a file named
326 `pspp.jnl' in the current directory. SET JOURNAL may be used to
329 * The use of `+' between syntax file names on the command line to
330 prevent the dictionary from being cleared between their
331 executions is no longer supported. All syntax files are now
332 executed as if `+' had been specified.
334 * The -d/--define and -u/--undef command line options are no
335 longer supported. Instead, use /usr/bin/env or shell primitives
336 to define or clear environment variables before invoking PSPP.
338 * If a syntax file named named `rc' is found in a configuration
339 directory (such as $HOME/.pspp), it is executed before any
340 syntax file specified on the command line. The -r or
341 --no-statrc command line option may be used to disable this
346 * Output configuration options have changed. Please refer to the
347 manual for a full description of the available options.
349 In consequence, you will need to reinstall your "devices" file.
350 "make install" will do this for you.
352 * Most error messages are now written to PSPP output files by
353 default. SET ERROR can be used to disable this behavior.
355 * When invoked interactively, PSPP now by default produces output
356 on the terminal, piping it through the "more" program.
357 Previously, by default output was written only to file
358 pspp.list. On most terminals, the page length used for output
359 automatically adapts to the terminal size, even if the terminal
364 - This driver now supports charts in output. Charts are written
365 as separate files that the main output file refers to. By
366 default, charts are written in PNG format to files named
367 pspp-1.png, pspp-2.png, and so on.
369 - Configurations are provided that use VT100 (and xterm)
370 line-drawing characters in tables. The option "-o list-vt100"
371 requests use of this device for output to pspp.list.
375 - The default paper size is now determined using the PAPERSIZE
376 environment variable, or the LC_PAPER locale category on
377 systems that support it. If these are not set, the default is
378 now A4, instead of US letter. To make US letter the default,
379 set PAPERSIZE to "letter" in your environment.
381 - Font metrics are now read from AFM files, instead of
382 Groff-format metrics files. PostScript fonts can now be
385 In consequence, you will need to install an AFM file for each
386 font used in PostScript output. "make install" will install
387 AFM files for the standard PostScript fonts, including the
388 ones that the PostScript driver uses by default.
390 - Standard paper sizes no longer need to be specified through a
391 configuration file. The "papersize" configuration file is no
392 longer needed, or supported.
394 - The PostScript prologue is no longer obtained from the
395 "ps-prologue" configuration file. This configuration file is
396 no longer needed, or supported.
400 - The HTML prologue is no longer obtained from the
401 "html-prologue" configuration file. This configuration file
402 is no longer needed, or supported.
404 Command language changes:
406 * The following commands are new:
408 - GET DATA, which currently supports reading Gnumeric files and
409 text data files. It will be extended later to read other
410 types of foreign data.
412 - CD, to change the current directory.
414 - INSERT, to execute a syntax file.
416 - DELETE VARIABLES, to remove variables from the active file
419 - ADD DOCUMENT, to add text to active file documents.
421 - CLOSE FILE HANDLE (a PSPP extension; see below).
423 - XEXPORT, a PSPP extension that is a transformation equivalent
426 * The following functions for transformation expressions are new:
428 - DATEDIFF, for computing the difference of two dates.
430 - DATESUM, for advancing a date by a specified duration.
432 - VALUELABEL, to obtain the value label for a value.
434 * PSPP now supports very long string variables (over 255 bytes
437 * MATCH FILES now supports the FIRST and LAST subcommands.
439 * Previous versions of PSPP prohibited using commands to both read and
440 write a single file at the same time. Now, PSPP allows this, and
441 the new version of the file atomically replaces the old version.
443 * The following commands are no longer available. They will be
444 re-implemented in a later release:
446 - CLEAR TRANSFORMATIONS
452 * The PROCESS IF command, which was deprecated, has been removed.
453 You may replace any usage of it by SELECT IF following
454 TEMPORARY, which has the same effect.
456 * The output format for variables created by VECTOR may now be
457 specified as part of the VECTOR syntax.
459 "Scratch files", a new PSPP extension:
461 A scratch file, like a system file, consists of a dictionary and
462 any number of cases. Small scratch files are stored in memory;
463 one that grows too large is written to disk. By default, any file
464 handle whose name begins with # is assumed to refer to a scratch
467 Scratch files can be used just about anywhere a system or portable
468 file can be used. Also, portable files are now allowed in most
469 places that system files were allowed in previous PSPP version.
471 A new CLOSE FILE HANDLE command allows the storage associated with
472 scratch files to be freed. It also allows file handles to be
473 reassigned to new files.
475 For more information on scratch files, refer to the "File Handles"
476 section in the PSPP manual. For specifics of what commands now
477 allow what kinds of files to be specified, refer to the
478 documentation on those particular commands.
482 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
483 translation, are now supported. Use FILE HANDLE to specify the
484 format of these files.
486 * Little-endian, big-endian, and VAX-endian formats are now
487 supported for integer binary formats when reading and writing
488 data files. The new RIB and WIB subcommands on the SET command
489 control endianness of integer data. The default is the host's
492 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
493 floating point binary formats when reading and writing data
494 files. The new RRB and WRB subcommands on the SET command
495 control the floating point format. The default is the host's
496 native floating point format.
498 * DATA LIST now supports the SKIP subcommand, to skip records at
499 the beginning of a file. For compatibility, DATA LIST now
500 treats N format as F format for FREE and LIST format input.
502 * The SAVE and XSAVE commands now support the UNSELECTED,
503 PERMISSIONS, NAMES, and MAP subcommands.
505 * The EXPORT command has been re-implemented to obtain better
506 results. Support for the UNSELECTED, DIGITS, and TYPE
507 subcommands has been added.
509 * For compatibility, PRINT now inserts a space at the beginning of
510 every output line, even lines that would otherwise be blank,
511 when OUTFILE is specified. (The behavior of WRITE is
514 * For compatibility, PRINT EJECT now inserts the digit `1' at the
515 beginning of each line that should begin a new page.
517 * For compatibility, WRITE now outputs the system-missing value as
518 a field filled with spaces. Binary formats are an exception.
519 (The behavior of PRINT is unchanged.)
523 * Input and output format descriptions have been rewritten. They
524 now precisely describe what is accepted on input and written on
527 * The descriptions of the PSPP system and portable file formats
528 have been extensively revised and improved.
530 For developers, the build system now requires Autoconf 2.60 and
533 Changes from 0.3.0 to 0.4.0:
535 Changes in build dependencies:
537 * The GNU Scientific Library (libgsl), version 1.6 or later, is
540 * libplot from GNU plotutils is optional. Without it, the new
541 graphing features will not work. If you do not have it
542 installed, you must run `configure' with --without-libplot.
544 * libgmp2 is no longer a dependency.
546 Newly implemented commands and statistical features:
548 * EXAMINE, including its graphing features.
550 * FREQUENCIES now supports percentiles.
558 * SORT CASES now sorts stably, that is, two cases with equal sort
559 criteria will be in the same relative order before and after the
562 * T-TEST (re-written).
564 * DATE and USE. These commands are parsed but otherwise ignored,
565 to enhance compatibility with certain command files that invoke
568 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
569 currently have no effect on PSPP output, but their values are
570 written to and read from system files and thus may affect
571 third-party software.
573 * SET EPOCH implemented.
575 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
578 * FILE HANDLE now supports custom tab widths.
580 Long variable names (and other identifiers) are now supported. Up
581 to the first 64 bytes of each identifier is significant. PSPP now
582 reads and writes system files compatible with SPSS version 12.
584 New --algorithm and --syntax command line options allow
585 SPSS-compatible or enhanced modes to be selected.
587 Support for transformation expressions has been rewritten and
588 significantly improved. Refer to the manual for details.
590 Calculation of moments (mean, standard deviation, kurtosis,
591 skewness) has been rewritten and should now be more accurate. In
592 --algorithm=enhanced mode moments may be more accurate than SPSS in
595 Numerous bugs have been fixed, too many to mention here. Many new
596 tests have been added, leading to the discovery and fixing of many
599 The ASCII output driver can now squeeze multiple blank lines into
602 Much of the code has been rewritten and refactored. It is now much
605 The FILE TYPE and REPEATING DATA commands have been disabled for
606 this release because their implementations were deemed too buggy to
607 be useful. They will be fixed and replaced in a future release.
609 New pspp-mode for Emacs (in pspp-mode.el).
611 Added rudimentary command-line completion for interactive input.
613 lib/julcal and lib/dcdflib are no longer used, so they have been
616 For developers, the build system now requires Autoconf 2.58 and
617 Automake 1.7. The included gettext has been updated to version
620 Some reports state that Texinfo 4.8, the latest version, may be
621 necessary to successfully format the documentation on some systems.
623 Version 0.3.0 changes since 0.2.3:
627 * Using alphanumeric variables in functions under AGGREGATE
630 * Under certain circumstances, the final case would be omitted
631 from the results of an AGGREGATE operation. Fixed.
633 * Undefined behavior was invoked by referencing a freed pointer
634 under certain circumstances. Fixed.
636 * A wrong record size was displayed when paging the active file to
639 * Not having enough temporary space for sorting caused a core
642 * Syntax errors in function descriptions on AGGREGATE caused core
645 * A null pointer was dereferenced, causing a core dump, when
646 PERCENTILES was specified on FREQUENCIES. This fixes the
647 problem, but PSPP still doesn't calculate percentiles.
649 * SORT always sorted in ascending order. Fixed.
651 * Some minor memory leaks in the expression parser were removed.
653 * Many assertions fixed for strict ANSI C compliance.
657 * SET ECHO ON now implemented, but turned off by default.
659 * PRINT specifier supported on END REPEAT.
663 * System libgmp2 library is used if installed instead of
664 unconditionally using the included libgmp2 subset.
666 * Extensive code cleanup, which continues.
668 * Added CORRELATIONS command parser, but not implemented.
670 Version 0.2.3 changes since 0.2.2:
674 * SPLIT FILE with a string variable caused a core dump. Fixed.
676 * Nested INCLUDEs didn't work. Fixed.
678 * The MATCH FILES procedure set the values of variables not present
679 to 0. It should have been SYSMIS. This is now fixed.
681 * The REMARK command was too aggressive about skipping lines. It
682 didn't like being the last command in a file.
684 * Comment parsing wasn't consistent with the rest of the code in its
685 idea of where one command ends and another starts. This meant
686 that sometimes commands would be mysteriously ignored. Thanks to
687 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
689 * The TABLE subcommand on MATCH FILES worked only erratically at
690 best. This fixes it. Thanks to Dr. Dirk Melcher
691 <BZN-mdksh@t-online.de> for reporting this bug.
693 * VARIABLE LABELS rejected a slash before the first variable
694 specification, contradicting the documentation. Thanks to Walter
695 M. Gray <graywm@northernc.on.ca> for reporting this bug.
697 * Because of an incorrect optimization in memory allocation,
698 CROSSTABS sometimes segfaulted when asked to output multiple
699 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
702 * CROSSTABS didn't display value labels for column and row
703 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
706 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
707 <BZN-mdksh@t-online.de> for reporting this bug.
709 * The TABLE subcommand on MATCH FILES worked only erratically at
710 best. This fixes it. Thanks to Dr. Dirk Melcher
711 <BZN-mdksh@t-online.de> for reporting this bug.
713 * VARIABLE LABELS rejected a slash before the first variable
714 specification, contradicting the documentation. Thanks to Walter
715 M. Gray <graywm@northernc.on.ca> for reporting this bug.
717 * Because of an incorrect optimization in memory allocation,
718 CROSSTABS sometimes segfaulted when asked to output multiple
719 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
722 * CROSSTABS didn't display value labels for column and row
723 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
726 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
727 <BZN-mdksh@t-online.de> for reporting this bug.
729 * MATCH FILES corrupted memory and dumped core on some syntax
732 * MATCH FILES should set numeric values not available to the
733 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
734 <BZN-mdksh@t-online.de> for reporting this bug.
736 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
737 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
741 * Some systems didn't like the way open_file was coded. Thanks to
742 Hankin <hankin@rogue.consultco.com> for pointing this out.
744 * The SAVE procedure didn't save long string variables properly.
745 Fixed by this patch. Thanks to Hankin
746 <hankin@rogue.consultco.com> for this patch.
748 * Minor documentation fixes for MATCH FILES.
750 Version 0.2.2 changes since 0.2.1:
754 * Fix behavior of PRINT SPACE for negative arguments.
756 * Fix reading some unusual system files.
758 * Fix LIST problems with very long variables. Thanks to Hankin
759 <hankin@dunno.com> for this bug report.
761 * Fix problems with some string format specifiers.
763 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
764 <BZN-mdksh@t-online.de> for reporting this bug.
766 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
767 Hankin <hankin@dunno.com> again on this one.
769 * Sometimes you may encounter a PSPP script that has to be
770 interpreted in interactive mode. Now you can use the -i flag to
773 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
774 `unused variable' warnings under gcc 2.7.2.3, fixing this will
779 * The files in gmp need the internationalization directory in
780 their include path. Thanks to OKUJI Yoshinori
781 <okuji@kuicr.kyoto-u.ac.jp> for pointing this out.
783 Version 0.2.1 changes since 0.2.0:
787 * Remember to include examples/ directory in distribution :-)
789 * Fixed gmp compile problems for some non-i386 architectures.
790 Thanks to Hans Olav Eggestad <olav@jordforsk.nlh.no> and others
793 * DATA LIST FREE and DATA LIST LIST parsing of input files is now
