7 Changes from 0.6.2 to 0.7.10:
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 * Text data files that PRINT and WRITE creates now use the system
140 native line ends by default (CRLF on Windows, LF only elsewhere).
141 Use the new ENDS subcommand on FILE HANDLE to override the default.
143 * A new Perl module allows Perl programs to read and write PSPP
146 * A tutorial chapter has been added to the user manual.
148 Changes from 0.6.1 to 0.6.2:
152 - Dutch, thanks to Harry Thijssen.
154 - Brazilian Portuguese, thanks to Michel Boaventura.
156 Thanks for translations are also due to the coordinators at
157 translationproject.org.
159 * Statistical bug fixes:
161 - REGRESSION: Report correct standard error of the estimate (bug
164 - T-TEST: Report correct significance of paired sample T-test in
165 the common case (bug #26936) and corner cases. Thanks to Mike
166 Griffiths and Matej Cepl for reporting these bugs.
168 * Build fixes and changes:
170 - Fix build with GTK+ 2.17.4 and later.
172 - Make running "make" after running "configure" with different
173 settings reliably rebuild version.c.
175 - Cygwin and MinGW build fixes.
177 - Fixes for building with recent gnulib.
179 - The Makefile now honors two new variables, PSPP_LDFLAGS and
180 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
181 binaries, respectively. This makes building easier for some
184 - Fixes for "configure --enable-relocatable" (bug #25508).
186 * Data file bug fixes and changes:
188 - Fix reading text data files that contain a mix of white space
189 and commas. Now "a ,b" is treated as two fields containing "a"
190 and "b"; previously it was treated as three, with an empty field
193 - Fix writing corrupted .sav files on Windows.
195 - Fix writing variable labels longer than 252 bytes to save files.
196 Thanks to Robert Westlund for reporting this bug.
198 - Fix writing corrupted .por files (bug #26034).
200 - Fix reading .por files whose initial lines are not padded out
201 with spaces as expected.
203 - PSPP will no longer issue warnings about some .sav file records
204 or values that it does not understand. These warnings were
205 harmless, but needlessly alarmed some users.
207 - Fix crash reading empty string fields from PostgreSQL databases.
209 * Bug fixes that affect PSPP and PSPPIRE:
211 - Users may now control precision of output statistics. Instead
212 of hard coding the width and decimals of output numbers, respect
213 the default format in most instances. Counts are now normally
214 displayed with the format of the weight variable, if any.
216 - Fix crash when an INSERT command specifies the name of a file
217 that does not exist (bug #24569).
219 - Fix crash when CROSSTABS specifies a long-string variable (bugs
222 - Fix crash drawing pie charts with many segments.
224 - Fix crash when NUMERIC specifies an invalid format.
226 * PSPPIRE bug fixes and changes:
228 - On Windows, write the output file to the user's home directory
229 instead of the current directory, to better match user
232 - Some data editor fixes.
236 - Fix typo in BINOMIAL section of user manual (bug #25892).
238 Changes from 0.6.0 to 0.6.1:
240 * Statistical bug fixes:
242 - Report correct standardized regression coefficients in linear
243 regression output (bug #23567).
245 * Bug fixes that affect PSPP and PSPPIRE:
247 - Avoid crash with pie charts (bug #24014).
249 - Don't append % to count totals (bug #24003).
251 - Don't crash on bad input (bug #24031).
253 - Don't crash if "end data." is not left aligned (bug #24115).
255 - Change default workspace value to 64 MB, to avoid unnecessary
256 disk accesses on modern machines.
260 - Add ".sav" or ".por" suffix to filename when saving with Save_As
263 - Make it possible to reopen the output window on Windows (bug
266 - A POSIX regular expression library is now included and used
267 automatically if the host does not have one or has one that is
270 * Build fixes and changes:
272 - Work around bug in GSL that prevented build with recent GCC
273 versions without manually adding -fgnu89-inline to CFLAGS.
275 - Also warn about missing prerequisites as we encounter them (bug
278 - Distribute necessary files to allow users working from the
279 distributed tarball to configure with --enable-gui-tools.
281 - Append $(EXEEXT_FOR_BUILD) to output file name when building
282 q2c, fixing build problems on Windows.
284 - GSL 1.8 or later is now required.
286 - Build errors with --enable-relocatable were fixed.
288 * The German translations were removed, since native German speakers
289 found them too poor to be useful.
291 Changes from 0.4.0 to 0.6.0:
293 * The PSPP license is now version 3 or later of the GNU General
294 Public License. Previously, it was version 2 or later.
296 * PSPP now has a graphical interface, called PSPPIRE. This
297 interface allows you to enter data and variable definitions
298 interactively. Commands may be executed in syntax form, or by
299 using the interactive dialog boxes available from the dropdown
302 * A few sample syntax files are now included in the `examples'
305 * Numerous major and minor bugs have been fixed.
309 * The INSTALL file now reflects the details of how to install
310 PSPP. It is a tailored version of the generic installation
311 instructions, instead of a verbatim copy.
313 * iconv, which is ordinarily installed as part of a Unix-like
314 system, is now required. If you don't have it already, you can
315 install GNU libiconv (http://www.gnu.org/software/libiconv/).
317 * libxml2 and zlib are new optional dependencies. They are
318 required to use PSPP's support for reading Gnumeric files.
320 Statistical procedure changes:
322 * REGRESSION is a new procedure for fitting linear models to data
323 via least-squares estimation.
325 * NPAR TESTS is a new procedure for non-parametric tests. In this
326 release, it supports binomial and chi-square tests.
328 * RANK is a new procedure to rank variables. It supports numerous
331 * FREQUENCIES can now output histograms and pie charts. These
332 features were present in earlier releases, but not documented.
334 User interface changes:
336 * In many situations where PSPP once terminated with a fatal
337 error, PSPP now recovers and continues execution.
339 * PSPP is now able to start up and run even if it cannot find its
342 * Journaling of interactive commands to a disk file is now
343 implemented. By default, journaling is enabled, to a file named
344 `pspp.jnl' in the current directory. SET JOURNAL may be used to
347 * The use of `+' between syntax file names on the command line to
348 prevent the dictionary from being cleared between their
349 executions is no longer supported. All syntax files are now
350 executed as if `+' had been specified.
352 * The -d/--define and -u/--undef command line options are no
353 longer supported. Instead, use /usr/bin/env or shell primitives
354 to define or clear environment variables before invoking PSPP.
356 * If a syntax file named named `rc' is found in a configuration
357 directory (such as $HOME/.pspp), it is executed before any
358 syntax file specified on the command line. The -r or
359 --no-statrc command line option may be used to disable this
364 * Output configuration options have changed. Please refer to the
365 manual for a full description of the available options.
367 In consequence, you will need to reinstall your "devices" file.
368 "make install" will do this for you.
370 * Most error messages are now written to PSPP output files by
371 default. SET ERROR can be used to disable this behavior.
373 * When invoked interactively, PSPP now by default produces output
374 on the terminal, piping it through the "more" program.
375 Previously, by default output was written only to file
376 pspp.list. On most terminals, the page length used for output
377 automatically adapts to the terminal size, even if the terminal
382 - This driver now supports charts in output. Charts are written
383 as separate files that the main output file refers to. By
384 default, charts are written in PNG format to files named
385 pspp-1.png, pspp-2.png, and so on.
387 - Configurations are provided that use VT100 (and xterm)
388 line-drawing characters in tables. The option "-o list-vt100"
389 requests use of this device for output to pspp.list.
393 - The default paper size is now determined using the PAPERSIZE
394 environment variable, or the LC_PAPER locale category on
395 systems that support it. If these are not set, the default is
396 now A4, instead of US letter. To make US letter the default,
397 set PAPERSIZE to "letter" in your environment.
399 - Font metrics are now read from AFM files, instead of
400 Groff-format metrics files. PostScript fonts can now be
403 In consequence, you will need to install an AFM file for each
404 font used in PostScript output. "make install" will install
405 AFM files for the standard PostScript fonts, including the
406 ones that the PostScript driver uses by default.
408 - Standard paper sizes no longer need to be specified through a
409 configuration file. The "papersize" configuration file is no
410 longer needed, or supported.
412 - The PostScript prologue is no longer obtained from the
413 "ps-prologue" configuration file. This configuration file is
414 no longer needed, or supported.
418 - The HTML prologue is no longer obtained from the
419 "html-prologue" configuration file. This configuration file
420 is no longer needed, or supported.
422 Command language changes:
424 * The following commands are new:
426 - GET DATA, which currently supports reading Gnumeric files and
427 text data files. It will be extended later to read other
428 types of foreign data.
430 - CD, to change the current directory.
432 - INSERT, to execute a syntax file.
434 - DELETE VARIABLES, to remove variables from the active file
437 - ADD DOCUMENT, to add text to active file documents.
439 - CLOSE FILE HANDLE (a PSPP extension; see below).
441 - XEXPORT, a PSPP extension that is a transformation equivalent
444 * The following functions for transformation expressions are new:
446 - DATEDIFF, for computing the difference of two dates.
448 - DATESUM, for advancing a date by a specified duration.
450 - VALUELABEL, to obtain the value label for a value.
452 * PSPP now supports very long string variables (over 255 bytes
455 * MATCH FILES now supports the FIRST and LAST subcommands.
457 * Previous versions of PSPP prohibited using commands to both read and
458 write a single file at the same time. Now, PSPP allows this, and
459 the new version of the file atomically replaces the old version.
461 * The following commands are no longer available. They will be
462 re-implemented in a later release:
464 - CLEAR TRANSFORMATIONS
470 * The PROCESS IF command, which was deprecated, has been removed.
471 You may replace any usage of it by SELECT IF following
472 TEMPORARY, which has the same effect.
474 * The output format for variables created by VECTOR may now be
475 specified as part of the VECTOR syntax.
477 "Scratch files", a new PSPP extension:
479 A scratch file, like a system file, consists of a dictionary and
480 any number of cases. Small scratch files are stored in memory;
481 one that grows too large is written to disk. By default, any file
482 handle whose name begins with # is assumed to refer to a scratch
485 Scratch files can be used just about anywhere a system or portable
486 file can be used. Also, portable files are now allowed in most
487 places that system files were allowed in previous PSPP version.
489 A new CLOSE FILE HANDLE command allows the storage associated with
490 scratch files to be freed. It also allows file handles to be
491 reassigned to new files.
493 For more information on scratch files, refer to the "File Handles"
494 section in the PSPP manual. For specifics of what commands now
495 allow what kinds of files to be specified, refer to the
496 documentation on those particular commands.
500 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
501 translation, are now supported. Use FILE HANDLE to specify the
502 format of these files.
504 * Little-endian, big-endian, and VAX-endian formats are now
505 supported for integer binary formats when reading and writing
506 data files. The new RIB and WIB subcommands on the SET command
507 control endianness of integer data. The default is the host's
510 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
511 floating point binary formats when reading and writing data
512 files. The new RRB and WRB subcommands on the SET command
513 control the floating point format. The default is the host's
514 native floating point format.
516 * DATA LIST now supports the SKIP subcommand, to skip records at
517 the beginning of a file. For compatibility, DATA LIST now
518 treats N format as F format for FREE and LIST format input.
520 * The SAVE and XSAVE commands now support the UNSELECTED,
521 PERMISSIONS, NAMES, and MAP subcommands.
523 * The EXPORT command has been re-implemented to obtain better
524 results. Support for the UNSELECTED, DIGITS, and TYPE
525 subcommands has been added.
527 * For compatibility, PRINT now inserts a space at the beginning of
528 every output line, even lines that would otherwise be blank,
529 when OUTFILE is specified. (The behavior of WRITE is
532 * For compatibility, PRINT EJECT now inserts the digit `1' at the
533 beginning of each line that should begin a new page.
535 * For compatibility, WRITE now outputs the system-missing value as
536 a field filled with spaces. Binary formats are an exception.
537 (The behavior of PRINT is unchanged.)
541 * Input and output format descriptions have been rewritten. They
542 now precisely describe what is accepted on input and written on
545 * The descriptions of the PSPP system and portable file formats
546 have been extensively revised and improved.
548 For developers, the build system now requires Autoconf 2.60 and
551 Changes from 0.3.0 to 0.4.0:
553 Changes in build dependencies:
555 * The GNU Scientific Library (libgsl), version 1.6 or later, is
558 * libplot from GNU plotutils is optional. Without it, the new
559 graphing features will not work. If you do not have it
560 installed, you must run `configure' with --without-libplot.
562 * libgmp2 is no longer a dependency.
564 Newly implemented commands and statistical features:
566 * EXAMINE, including its graphing features.
568 * FREQUENCIES now supports percentiles.
576 * SORT CASES now sorts stably, that is, two cases with equal sort
577 criteria will be in the same relative order before and after the
580 * T-TEST (re-written).
582 * DATE and USE. These commands are parsed but otherwise ignored,
583 to enhance compatibility with certain command files that invoke
586 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
587 currently have no effect on PSPP output, but their values are
588 written to and read from system files and thus may affect
589 third-party software.
591 * SET EPOCH implemented.
593 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
596 * FILE HANDLE now supports custom tab widths.
598 Long variable names (and other identifiers) are now supported. Up
599 to the first 64 bytes of each identifier is significant. PSPP now
600 reads and writes system files compatible with SPSS version 12.
602 New --algorithm and --syntax command line options allow
603 SPSS-compatible or enhanced modes to be selected.
605 Support for transformation expressions has been rewritten and
606 significantly improved. Refer to the manual for details.
608 Calculation of moments (mean, standard deviation, kurtosis,
609 skewness) has been rewritten and should now be more accurate. In
610 --algorithm=enhanced mode moments may be more accurate than SPSS in
613 Numerous bugs have been fixed, too many to mention here. Many new
614 tests have been added, leading to the discovery and fixing of many
617 The ASCII output driver can now squeeze multiple blank lines into
620 Much of the code has been rewritten and refactored. It is now much
623 The FILE TYPE and REPEATING DATA commands have been disabled for
624 this release because their implementations were deemed too buggy to
625 be useful. They will be fixed and replaced in a future release.
627 New pspp-mode for Emacs (in pspp-mode.el).
629 Added rudimentary command-line completion for interactive input.
631 lib/julcal and lib/dcdflib are no longer used, so they have been
634 For developers, the build system now requires Autoconf 2.58 and
635 Automake 1.7. The included gettext has been updated to version
638 Some reports state that Texinfo 4.8, the latest version, may be
639 necessary to successfully format the documentation on some systems.
641 Version 0.3.0 changes since 0.2.3:
645 * Using alphanumeric variables in functions under AGGREGATE
648 * Under certain circumstances, the final case would be omitted
649 from the results of an AGGREGATE operation. Fixed.
651 * Undefined behavior was invoked by referencing a freed pointer
652 under certain circumstances. Fixed.
654 * A wrong record size was displayed when paging the active file to
657 * Not having enough temporary space for sorting caused a core
660 * Syntax errors in function descriptions on AGGREGATE caused core
663 * A null pointer was dereferenced, causing a core dump, when
664 PERCENTILES was specified on FREQUENCIES. This fixes the
665 problem, but PSPP still doesn't calculate percentiles.
667 * SORT always sorted in ascending order. Fixed.
669 * Some minor memory leaks in the expression parser were removed.
671 * Many assertions fixed for strict ANSI C compliance.
675 * SET ECHO ON now implemented, but turned off by default.
677 * PRINT specifier supported on END REPEAT.
681 * System libgmp2 library is used if installed instead of
682 unconditionally using the included libgmp2 subset.
684 * Extensive code cleanup, which continues.
686 * Added CORRELATIONS command parser, but not implemented.
688 Version 0.2.3 changes since 0.2.2:
692 * SPLIT FILE with a string variable caused a core dump. Fixed.
694 * Nested INCLUDEs didn't work. Fixed.
696 * The MATCH FILES procedure set the values of variables not present
697 to 0. It should have been SYSMIS. This is now fixed.
699 * The REMARK command was too aggressive about skipping lines. It
700 didn't like being the last command in a file.
702 * Comment parsing wasn't consistent with the rest of the code in its
703 idea of where one command ends and another starts. This meant
704 that sometimes commands would be mysteriously ignored. Thanks to
705 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
707 * The TABLE subcommand on MATCH FILES worked only erratically at
708 best. This fixes it. Thanks to Dr. Dirk Melcher
709 <BZN-mdksh@t-online.de> for reporting this bug.
711 * VARIABLE LABELS rejected a slash before the first variable
712 specification, contradicting the documentation. Thanks to Walter
713 M. Gray <graywm@northernc.on.ca> for reporting this bug.
715 * Because of an incorrect optimization in memory allocation,
716 CROSSTABS sometimes segfaulted when asked to output multiple
717 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
720 * CROSSTABS didn't display value labels for column and row
721 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
724 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
725 <BZN-mdksh@t-online.de> for reporting this bug.
727 * The TABLE subcommand on MATCH FILES worked only erratically at
728 best. This fixes it. Thanks to Dr. Dirk Melcher
729 <BZN-mdksh@t-online.de> for reporting this bug.
731 * VARIABLE LABELS rejected a slash before the first variable
732 specification, contradicting the documentation. Thanks to Walter
733 M. Gray <graywm@northernc.on.ca> for reporting this bug.
735 * Because of an incorrect optimization in memory allocation,
736 CROSSTABS sometimes segfaulted when asked to output multiple
737 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
740 * CROSSTABS didn't display value labels for column and row
741 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
744 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
745 <BZN-mdksh@t-online.de> for reporting this bug.
747 * MATCH FILES corrupted memory and dumped core on some syntax
750 * MATCH FILES should set numeric values not available to the
751 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
752 <BZN-mdksh@t-online.de> for reporting this bug.
754 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
755 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
759 * Some systems didn't like the way open_file was coded. Thanks to
760 Hankin <hankin@rogue.consultco.com> for pointing this out.
762 * The SAVE procedure didn't save long string variables properly.
763 Fixed by this patch. Thanks to Hankin
764 <hankin@rogue.consultco.com> for this patch.
766 * Minor documentation fixes for MATCH FILES.
768 Version 0.2.2 changes since 0.2.1:
772 * Fix behavior of PRINT SPACE for negative arguments.
774 * Fix reading some unusual system files.
776 * Fix LIST problems with very long variables. Thanks to Hankin
777 <hankin@dunno.com> for this bug report.
779 * Fix problems with some string format specifiers.
781 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
782 <BZN-mdksh@t-online.de> for reporting this bug.
784 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
785 Hankin <hankin@dunno.com> again on this one.
787 * Sometimes you may encounter a PSPP script that has to be
788 interpreted in interactive mode. Now you can use the -i flag to
791 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
792 `unused variable' warnings under gcc 2.7.2.3, fixing this will
797 * The files in gmp need the internationalization directory in
