7 Changes from 0.6.2 to 0.7.9:
24 - PRESERVE and RESTORE
28 - SAVE TRANSLATE to CSV and tab-delimited files
32 * Changes to existing commands:
34 - AUTORECODE has a new GROUP subcommand.
36 - CROSSTABS has been re-implemented to fix numerous bugs.
38 - EXAMINE: /MISSING=LISTWISE is now the default.
40 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
41 contains an INCLUDE or INSERT command, substitutions are not
42 applied to the included file.
44 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
46 - HOST has been updated to use more modern syntax.
48 - Most commands that work with data files now support a new
51 - MISSING VALUES can now assign missing values to long string
54 - ONEWAY: the POSTHOC subcommand is now implemented.
56 - The following new subcommands to NPAR TESTS have been implemented:
57 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
58 MCNEMAR, SIGN, WILCOXON, and RUNS
60 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
61 DPROMPT subcommands. The defaults are now fixed values.
63 - SHOW now has a JOURNAL subcommand, to show the location of the
66 - VALUE LABELS can now assign value labels to long string
69 * Other language changes:
71 - The new DATASET commands replace the "scratch file" PSPP
72 extension, which is no longer supported.
74 - Strings may now include arbitrary Unicode code points specified
75 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
76 code point U+1D11E, the musical G clef character, may be
77 expressed as U'1D11E'.
79 See the "Tokens" section in the PSPP manual for more information.
81 - In previous versions of PSPP, in a string expressed in
82 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
83 bytes in the locale encoding. In this version of PSPP, X'hh'
84 syntax always expresses bytes in UTF-8 encoding.
86 See the "Tokens" section in the PSPP manual for more information.
88 * PSPPIRE graphical user interface improvements:
90 - Added support for non-ASCII characters in strings, labels and
93 - A "Split Window" function is available, which makes it easier to
94 see different parts of a large data file.
96 - Data files can now be opened by specifing their name as the first
97 argument. This means that on a properly configured desktop, double
98 clicking on an icon will open the file.
102 - The new "cairo" output driver supports output in PostScript, PDF,
103 and SVG formats. Its functionality is a superset of that of the
104 "postscript" driver, which has been removed. You must have Cairo
105 and Pango installed to build the "cairo" driver.
107 - Charts are now produced with Cairo and Pango, instead of libplot.
108 Without them, the new graphing features will not work. If you do
109 not have Cairo and Pango installed, you must run `configure' with
112 - The plain text output driver now properly supports multibyte UTF-8
113 characters, including double-width characters and combining
116 - Output to OpenDocument format is now supported.
118 - The HTML output is much improved.
120 * The "pspp" program has a new option --batch (or -b) that selects
121 "batch" syntax mode. In previous versions of PSPP this syntax mode
122 was the default. Now a new "auto" syntax mode is the default. In
123 "auto" mode, PSPP interprets most syntax files correctly regardless
124 of their intended syntax mode.
126 See the "Syntax Variants" section in the PSPP manual for more
129 * The "pspp" program has a new option --syntax-encoding that
130 specifies the encoding for syntax files listed on the command line,
131 as well as the default encoding for syntax files included with
132 INCLUDE or INSERT. The default is to accept the system locale
133 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
134 one the system file uses.
136 See the documentation for the INSERT command in the PSPP manual for
139 * A new Perl module allows Perl programs to read and write PSPP
142 * A tutorial chapter has been added to the user manual.
144 Changes from 0.6.1 to 0.6.2:
148 - Dutch, thanks to Harry Thijssen.
150 - Brazilian Portuguese, thanks to Michel Boaventura.
152 Thanks for translations are also due to the coordinators at
153 translationproject.org.
155 * Statistical bug fixes:
157 - REGRESSION: Report correct standard error of the estimate (bug
160 - T-TEST: Report correct significance of paired sample T-test in
161 the common case (bug #26936) and corner cases. Thanks to Mike
162 Griffiths and Matej Cepl for reporting these bugs.
164 * Build fixes and changes:
166 - Fix build with GTK+ 2.17.4 and later.
168 - Make running "make" after running "configure" with different
169 settings reliably rebuild version.c.
171 - Cygwin and MinGW build fixes.
173 - Fixes for building with recent gnulib.
175 - The Makefile now honors two new variables, PSPP_LDFLAGS and
176 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
177 binaries, respectively. This makes building easier for some
180 - Fixes for "configure --enable-relocatable" (bug #25508).
182 * Data file bug fixes and changes:
184 - Fix reading text data files that contain a mix of white space
185 and commas. Now "a ,b" is treated as two fields containing "a"
186 and "b"; previously it was treated as three, with an empty field
189 - Fix writing corrupted .sav files on Windows.
191 - Fix writing variable labels longer than 252 bytes to save files.
192 Thanks to Robert Westlund for reporting this bug.
194 - Fix writing corrupted .por files (bug #26034).
196 - Fix reading .por files whose initial lines are not padded out
197 with spaces as expected.
199 - PSPP will no longer issue warnings about some .sav file records
200 or values that it does not understand. These warnings were
201 harmless, but needlessly alarmed some users.
203 - Fix crash reading empty string fields from PostgreSQL databases.
205 * Bug fixes that affect PSPP and PSPPIRE:
207 - Users may now control precision of output statistics. Instead
208 of hard coding the width and decimals of output numbers, respect
209 the default format in most instances. Counts are now normally
210 displayed with the format of the weight variable, if any.
212 - Fix crash when an INSERT command specifies the name of a file
213 that does not exist (bug #24569).
215 - Fix crash when CROSSTABS specifies a long-string variable (bugs
218 - Fix crash drawing pie charts with many segments.
220 - Fix crash when NUMERIC specifies an invalid format.
222 * PSPPIRE bug fixes and changes:
224 - On Windows, write the output file to the user's home directory
225 instead of the current directory, to better match user
228 - Some data editor fixes.
232 - Fix typo in BINOMIAL section of user manual (bug #25892).
234 Changes from 0.6.0 to 0.6.1:
236 * Statistical bug fixes:
238 - Report correct standardized regression coefficients in linear
239 regression output (bug #23567).
241 * Bug fixes that affect PSPP and PSPPIRE:
243 - Avoid crash with pie charts (bug #24014).
245 - Don't append % to count totals (bug #24003).
247 - Don't crash on bad input (bug #24031).
249 - Don't crash if "end data." is not left aligned (bug #24115).
251 - Change default workspace value to 64 MB, to avoid unnecessary
252 disk accesses on modern machines.
256 - Add ".sav" or ".por" suffix to filename when saving with Save_As
259 - Make it possible to reopen the output window on Windows (bug
262 - A POSIX regular expression library is now included and used
263 automatically if the host does not have one or has one that is
266 * Build fixes and changes:
268 - Work around bug in GSL that prevented build with recent GCC
269 versions without manually adding -fgnu89-inline to CFLAGS.
271 - Also warn about missing prerequisites as we encounter them (bug
274 - Distribute necessary files to allow users working from the
275 distributed tarball to configure with --enable-gui-tools.
277 - Append $(EXEEXT_FOR_BUILD) to output file name when building
278 q2c, fixing build problems on Windows.
280 - GSL 1.8 or later is now required.
282 - Build errors with --enable-relocatable were fixed.
284 * The German translations were removed, since native German speakers
285 found them too poor to be useful.
287 Changes from 0.4.0 to 0.6.0:
289 * The PSPP license is now version 3 or later of the GNU General
290 Public License. Previously, it was version 2 or later.
292 * PSPP now has a graphical interface, called PSPPIRE. This
293 interface allows you to enter data and variable definitions
294 interactively. Commands may be executed in syntax form, or by
295 using the interactive dialog boxes available from the dropdown
298 * A few sample syntax files are now included in the `examples'
301 * Numerous major and minor bugs have been fixed.
305 * The INSTALL file now reflects the details of how to install
306 PSPP. It is a tailored version of the generic installation
307 instructions, instead of a verbatim copy.
309 * iconv, which is ordinarily installed as part of a Unix-like
310 system, is now required. If you don't have it already, you can
311 install GNU libiconv (http://www.gnu.org/software/libiconv/).
313 * libxml2 and zlib are new optional dependencies. They are
314 required to use PSPP's support for reading Gnumeric files.
316 Statistical procedure changes:
318 * REGRESSION is a new procedure for fitting linear models to data
319 via least-squares estimation.
321 * NPAR TESTS is a new procedure for non-parametric tests. In this
322 release, it supports binomial and chi-square tests.
324 * RANK is a new procedure to rank variables. It supports numerous
327 * FREQUENCIES can now output histograms and pie charts. These
328 features were present in earlier releases, but not documented.
330 User interface changes:
332 * In many situations where PSPP once terminated with a fatal
333 error, PSPP now recovers and continues execution.
335 * PSPP is now able to start up and run even if it cannot find its
338 * Journaling of interactive commands to a disk file is now
339 implemented. By default, journaling is enabled, to a file named
340 `pspp.jnl' in the current directory. SET JOURNAL may be used to
343 * The use of `+' between syntax file names on the command line to
344 prevent the dictionary from being cleared between their
345 executions is no longer supported. All syntax files are now
346 executed as if `+' had been specified.
348 * The -d/--define and -u/--undef command line options are no
349 longer supported. Instead, use /usr/bin/env or shell primitives
350 to define or clear environment variables before invoking PSPP.
352 * If a syntax file named named `rc' is found in a configuration
353 directory (such as $HOME/.pspp), it is executed before any
354 syntax file specified on the command line. The -r or
355 --no-statrc command line option may be used to disable this
360 * Output configuration options have changed. Please refer to the
361 manual for a full description of the available options.
363 In consequence, you will need to reinstall your "devices" file.
364 "make install" will do this for you.
366 * Most error messages are now written to PSPP output files by
367 default. SET ERROR can be used to disable this behavior.
369 * When invoked interactively, PSPP now by default produces output
370 on the terminal, piping it through the "more" program.
371 Previously, by default output was written only to file
372 pspp.list. On most terminals, the page length used for output
373 automatically adapts to the terminal size, even if the terminal
378 - This driver now supports charts in output. Charts are written
379 as separate files that the main output file refers to. By
380 default, charts are written in PNG format to files named
381 pspp-1.png, pspp-2.png, and so on.
383 - Configurations are provided that use VT100 (and xterm)
384 line-drawing characters in tables. The option "-o list-vt100"
385 requests use of this device for output to pspp.list.
389 - The default paper size is now determined using the PAPERSIZE
390 environment variable, or the LC_PAPER locale category on
391 systems that support it. If these are not set, the default is
392 now A4, instead of US letter. To make US letter the default,
393 set PAPERSIZE to "letter" in your environment.
395 - Font metrics are now read from AFM files, instead of
396 Groff-format metrics files. PostScript fonts can now be
399 In consequence, you will need to install an AFM file for each
400 font used in PostScript output. "make install" will install
401 AFM files for the standard PostScript fonts, including the
402 ones that the PostScript driver uses by default.
404 - Standard paper sizes no longer need to be specified through a
405 configuration file. The "papersize" configuration file is no
406 longer needed, or supported.
408 - The PostScript prologue is no longer obtained from the
409 "ps-prologue" configuration file. This configuration file is
410 no longer needed, or supported.
414 - The HTML prologue is no longer obtained from the
415 "html-prologue" configuration file. This configuration file
416 is no longer needed, or supported.
418 Command language changes:
420 * The following commands are new:
422 - GET DATA, which currently supports reading Gnumeric files and
423 text data files. It will be extended later to read other
424 types of foreign data.
426 - CD, to change the current directory.
428 - INSERT, to execute a syntax file.
430 - DELETE VARIABLES, to remove variables from the active file
433 - ADD DOCUMENT, to add text to active file documents.
435 - CLOSE FILE HANDLE (a PSPP extension; see below).
437 - XEXPORT, a PSPP extension that is a transformation equivalent
440 * The following functions for transformation expressions are new:
442 - DATEDIFF, for computing the difference of two dates.
444 - DATESUM, for advancing a date by a specified duration.
446 - VALUELABEL, to obtain the value label for a value.
448 * PSPP now supports very long string variables (over 255 bytes
451 * MATCH FILES now supports the FIRST and LAST subcommands.
453 * Previous versions of PSPP prohibited using commands to both read and
454 write a single file at the same time. Now, PSPP allows this, and
455 the new version of the file atomically replaces the old version.
457 * The following commands are no longer available. They will be
458 re-implemented in a later release:
460 - CLEAR TRANSFORMATIONS
466 * The PROCESS IF command, which was deprecated, has been removed.
467 You may replace any usage of it by SELECT IF following
468 TEMPORARY, which has the same effect.
470 * The output format for variables created by VECTOR may now be
471 specified as part of the VECTOR syntax.
473 "Scratch files", a new PSPP extension:
475 A scratch file, like a system file, consists of a dictionary and
476 any number of cases. Small scratch files are stored in memory;
477 one that grows too large is written to disk. By default, any file
478 handle whose name begins with # is assumed to refer to a scratch
481 Scratch files can be used just about anywhere a system or portable
482 file can be used. Also, portable files are now allowed in most
483 places that system files were allowed in previous PSPP version.
485 A new CLOSE FILE HANDLE command allows the storage associated with
486 scratch files to be freed. It also allows file handles to be
487 reassigned to new files.
489 For more information on scratch files, refer to the "File Handles"
490 section in the PSPP manual. For specifics of what commands now
491 allow what kinds of files to be specified, refer to the
492 documentation on those particular commands.
496 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
497 translation, are now supported. Use FILE HANDLE to specify the
498 format of these files.
500 * Little-endian, big-endian, and VAX-endian formats are now
501 supported for integer binary formats when reading and writing
502 data files. The new RIB and WIB subcommands on the SET command
503 control endianness of integer data. The default is the host's
506 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
507 floating point binary formats when reading and writing data
508 files. The new RRB and WRB subcommands on the SET command
509 control the floating point format. The default is the host's
510 native floating point format.
512 * DATA LIST now supports the SKIP subcommand, to skip records at
513 the beginning of a file. For compatibility, DATA LIST now
514 treats N format as F format for FREE and LIST format input.
516 * The SAVE and XSAVE commands now support the UNSELECTED,
517 PERMISSIONS, NAMES, and MAP subcommands.
519 * The EXPORT command has been re-implemented to obtain better
520 results. Support for the UNSELECTED, DIGITS, and TYPE
521 subcommands has been added.
523 * For compatibility, PRINT now inserts a space at the beginning of
524 every output line, even lines that would otherwise be blank,
525 when OUTFILE is specified. (The behavior of WRITE is
528 * For compatibility, PRINT EJECT now inserts the digit `1' at the
529 beginning of each line that should begin a new page.
531 * For compatibility, WRITE now outputs the system-missing value as
532 a field filled with spaces. Binary formats are an exception.
533 (The behavior of PRINT is unchanged.)
537 * Input and output format descriptions have been rewritten. They
538 now precisely describe what is accepted on input and written on
541 * The descriptions of the PSPP system and portable file formats
542 have been extensively revised and improved.
544 For developers, the build system now requires Autoconf 2.60 and
547 Changes from 0.3.0 to 0.4.0:
549 Changes in build dependencies:
551 * The GNU Scientific Library (libgsl), version 1.6 or later, is
554 * libplot from GNU plotutils is optional. Without it, the new
555 graphing features will not work. If you do not have it
556 installed, you must run `configure' with --without-libplot.
558 * libgmp2 is no longer a dependency.
560 Newly implemented commands and statistical features:
562 * EXAMINE, including its graphing features.
564 * FREQUENCIES now supports percentiles.
572 * SORT CASES now sorts stably, that is, two cases with equal sort
573 criteria will be in the same relative order before and after the
576 * T-TEST (re-written).
578 * DATE and USE. These commands are parsed but otherwise ignored,
579 to enhance compatibility with certain command files that invoke
582 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
583 currently have no effect on PSPP output, but their values are
584 written to and read from system files and thus may affect
585 third-party software.
587 * SET EPOCH implemented.
589 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
592 * FILE HANDLE now supports custom tab widths.
594 Long variable names (and other identifiers) are now supported. Up
595 to the first 64 bytes of each identifier is significant. PSPP now
596 reads and writes system files compatible with SPSS version 12.
598 New --algorithm and --syntax command line options allow
599 SPSS-compatible or enhanced modes to be selected.
601 Support for transformation expressions has been rewritten and
602 significantly improved. Refer to the manual for details.
604 Calculation of moments (mean, standard deviation, kurtosis,
605 skewness) has been rewritten and should now be more accurate. In
606 --algorithm=enhanced mode moments may be more accurate than SPSS in
609 Numerous bugs have been fixed, too many to mention here. Many new
610 tests have been added, leading to the discovery and fixing of many
613 The ASCII output driver can now squeeze multiple blank lines into
616 Much of the code has been rewritten and refactored. It is now much
619 The FILE TYPE and REPEATING DATA commands have been disabled for
620 this release because their implementations were deemed too buggy to
621 be useful. They will be fixed and replaced in a future release.
623 New pspp-mode for Emacs (in pspp-mode.el).
625 Added rudimentary command-line completion for interactive input.
627 lib/julcal and lib/dcdflib are no longer used, so they have been
630 For developers, the build system now requires Autoconf 2.58 and
631 Automake 1.7. The included gettext has been updated to version
634 Some reports state that Texinfo 4.8, the latest version, may be
635 necessary to successfully format the documentation on some systems.
637 Version 0.3.0 changes since 0.2.3:
641 * Using alphanumeric variables in functions under AGGREGATE
644 * Under certain circumstances, the final case would be omitted
645 from the results of an AGGREGATE operation. Fixed.
647 * Undefined behavior was invoked by referencing a freed pointer
648 under certain circumstances. Fixed.
650 * A wrong record size was displayed when paging the active file to
653 * Not having enough temporary space for sorting caused a core
656 * Syntax errors in function descriptions on AGGREGATE caused core
659 * A null pointer was dereferenced, causing a core dump, when
660 PERCENTILES was specified on FREQUENCIES. This fixes the
661 problem, but PSPP still doesn't calculate percentiles.
663 * SORT always sorted in ascending order. Fixed.
665 * Some minor memory leaks in the expression parser were removed.
667 * Many assertions fixed for strict ANSI C compliance.
671 * SET ECHO ON now implemented, but turned off by default.
673 * PRINT specifier supported on END REPEAT.
677 * System libgmp2 library is used if installed instead of
678 unconditionally using the included libgmp2 subset.
680 * Extensive code cleanup, which continues.
682 * Added CORRELATIONS command parser, but not implemented.
684 Version 0.2.3 changes since 0.2.2:
688 * SPLIT FILE with a string variable caused a core dump. Fixed.
690 * Nested INCLUDEs didn't work. Fixed.
692 * The MATCH FILES procedure set the values of variables not present
693 to 0. It should have been SYSMIS. This is now fixed.
695 * The REMARK command was too aggressive about skipping lines. It
696 didn't like being the last command in a file.
698 * Comment parsing wasn't consistent with the rest of the code in its
699 idea of where one command ends and another starts. This meant
700 that sometimes commands would be mysteriously ignored. Thanks to
701 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
703 * The TABLE subcommand on MATCH FILES worked only erratically at
704 best. This fixes it. Thanks to Dr. Dirk Melcher
705 <BZN-mdksh@t-online.de> for reporting this bug.
707 * VARIABLE LABELS rejected a slash before the first variable
708 specification, contradicting the documentation. Thanks to Walter
709 M. Gray <graywm@northernc.on.ca> for reporting this bug.
711 * Because of an incorrect optimization in memory allocation,
712 CROSSTABS sometimes segfaulted when asked to output multiple
713 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
716 * CROSSTABS didn't display value labels for column and row
717 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
720 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
721 <BZN-mdksh@t-online.de> for reporting this bug.
723 * The TABLE subcommand on MATCH FILES worked only erratically at
724 best. This fixes it. Thanks to Dr. Dirk Melcher
725 <BZN-mdksh@t-online.de> for reporting this bug.
727 * VARIABLE LABELS rejected a slash before the first variable
728 specification, contradicting the documentation. Thanks to Walter
729 M. Gray <graywm@northernc.on.ca> for reporting this bug.
731 * Because of an incorrect optimization in memory allocation,
732 CROSSTABS sometimes segfaulted when asked to output multiple
733 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
736 * CROSSTABS didn't display value labels for column and row
737 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
740 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
741 <BZN-mdksh@t-online.de> for reporting this bug.
743 * MATCH FILES corrupted memory and dumped core on some syntax
746 * MATCH FILES should set numeric values not available to the
747 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
748 <BZN-mdksh@t-online.de> for reporting this bug.
750 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
751 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
755 * Some systems didn't like the way open_file was coded. Thanks to
756 Hankin <hankin@rogue.consultco.com> for pointing this out.
758 * The SAVE procedure didn't save long string variables properly.
759 Fixed by this patch. Thanks to Hankin
760 <hankin@rogue.consultco.com> for this patch.
762 * Minor documentation fixes for MATCH FILES.
764 Version 0.2.2 changes since 0.2.1:
768 * Fix behavior of PRINT SPACE for negative arguments.
770 * Fix reading some unusual system files.
772 * Fix LIST problems with very long variables. Thanks to Hankin
773 <hankin@dunno.com> for this bug report.
775 * Fix problems with some string format specifiers.
777 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
778 <BZN-mdksh@t-online.de> for reporting this bug.
780 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
781 Hankin <hankin@dunno.com> again on this one.
783 * Sometimes you may encounter a PSPP script that has to be
784 interpreted in interactive mode. Now you can use the -i flag to
787 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
788 `unused variable' warnings under gcc 2.7.2.3, fixing this will
793 * The files in gmp need the internationalization directory in
794 their include path. Thanks to OKUJI Yoshinori
795 <okuji@kuicr.kyoto-u.ac.jp> for pointing this out.
797 Version 0.2.1 changes since 0.2.0:
