7 Changes from 0.6.2 to 0.7.9:
23 - PRESERVE and RESTORE
27 - SAVE TRANSLATE to CSV and tab-delimited files
31 * Changes to existing commands:
33 - AUTORECODE has a new GROUP subcommand.
35 - CROSSTABS has been re-implemented to fix numerous bugs.
37 - EXAMINE: /MISSING=LISTWISE is now the default.
39 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
40 contains an INCLUDE or INSERT command, substitutions are not
41 applied to the included file.
43 - HOST has been updated to use more modern syntax.
45 - GET, INCLUDE, and INSERT have a new ENCODING subcommand.
47 - MISSING VALUES can now assign missing values to long string
50 - ONEWAY: the POSTHOC subcommand is now implemented.
52 - The following new subcommands to NPAR TESTS have been implemented:
53 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
54 MCNEMAR, SIGN, WILCOXON, and RUNS
56 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
57 DPROMPT subcommands. The defaults are now fixed values.
59 - VALUE LABELS can now assign value labels to long string
62 * Other language changes:
64 - The new DATASET commands replace the "scratch file" PSPP
65 extension, which is no longer supported.
67 - Strings may now include arbitrary Unicode code points specified
68 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
69 code point U+1D11E, the musical G clef character, may be
70 expressed as U'1D11E'.
72 See the "Tokens" section in the PSPP manual for more information.
74 - In previous versions of PSPP, in a string expressed in
75 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
76 bytes in the locale encoding. In this version of PSPP, X'hh'
77 syntax always expresses bytes in UTF-8 encoding.
79 See the "Tokens" section in the PSPP manual for more information.
81 * PSPPIRE graphical user interface improvements:
83 - Added support for non-ASCII characters in strings, labels and
86 - A "Split Window" function is available, which makes it easier to
87 see different parts of a large data file.
89 - Data files can now be opened by specifing their name as the first
90 argument. This means that on a properly configured desktop, double
91 clicking on an icon will open the file.
95 - The new "cairo" output driver supports output in PostScript, PDF,
96 and SVG formats. Its functionality is a superset of that of the
97 "postscript" driver, which has been removed. You must have Cairo
98 and Pango installed to build the "cairo" driver.
100 - Charts are now produced with Cairo and Pango, instead of libplot.
101 Without them, the new graphing features will not work. If you do
102 not have Cairo and Pango installed, you must run `configure' with
105 - The plain text output driver now properly supports multibyte UTF-8
106 characters, including double-width characters and combining
109 - Output to OpenDocument format is now supported.
111 - The HTML output is much improved.
113 * The "pspp" program has a new option --batch (or -b) that selects
114 "batch" syntax mode. In previous versions of PSPP this syntax mode
115 was the default. Now a new "auto" syntax mode is the default. In
116 "auto" mode, PSPP interprets most syntax files correctly regardless
117 of their intended syntax mode.
119 See the "Syntax Variants" section in the PSPP manual for more
122 * The "pspp" program has a new option --syntax-encoding that
123 specifies the encoding for syntax files listed on the command line,
124 as well as the default encoding for syntax files included with
125 INCLUDE or INSERT. The default is to accept the system locale
126 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
127 one the system file uses.
129 See the documentation for the INSERT command in the PSPP manual for
132 * A new Perl module allows Perl programs to read and write PSPP
135 * A tutorial chapter has been added to the user manual.
137 Changes from 0.6.1 to 0.6.2:
141 - Dutch, thanks to Harry Thijssen.
143 - Brazilian Portuguese, thanks to Michel Boaventura.
145 Thanks for translations are also due to the coordinators at
146 translationproject.org.
148 * Statistical bug fixes:
150 - REGRESSION: Report correct standard error of the estimate (bug
153 - T-TEST: Report correct significance of paired sample T-test in
154 the common case (bug #26936) and corner cases. Thanks to Mike
155 Griffiths and Matej Cepl for reporting these bugs.
157 * Build fixes and changes:
159 - Fix build with GTK+ 2.17.4 and later.
161 - Make running "make" after running "configure" with different
162 settings reliably rebuild version.c.
164 - Cygwin and MinGW build fixes.
166 - Fixes for building with recent gnulib.
168 - The Makefile now honors two new variables, PSPP_LDFLAGS and
169 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
170 binaries, respectively. This makes building easier for some
173 - Fixes for "configure --enable-relocatable" (bug #25508).
175 * Data file bug fixes and changes:
177 - Fix reading text data files that contain a mix of white space
178 and commas. Now "a ,b" is treated as two fields containing "a"
179 and "b"; previously it was treated as three, with an empty field
182 - Fix writing corrupted .sav files on Windows.
184 - Fix writing variable labels longer than 252 bytes to save files.
185 Thanks to Robert Westlund for reporting this bug.
187 - Fix writing corrupted .por files (bug #26034).
189 - Fix reading .por files whose initial lines are not padded out
190 with spaces as expected.
192 - PSPP will no longer issue warnings about some .sav file records
193 or values that it does not understand. These warnings were
194 harmless, but needlessly alarmed some users.
196 - Fix crash reading empty string fields from PostgreSQL databases.
198 * Bug fixes that affect PSPP and PSPPIRE:
200 - Users may now control precision of output statistics. Instead
201 of hard coding the width and decimals of output numbers, respect
202 the default format in most instances. Counts are now normally
203 displayed with the format of the weight variable, if any.
205 - Fix crash when an INSERT command specifies the name of a file
206 that does not exist (bug #24569).
208 - Fix crash when CROSSTABS specifies a long-string variable (bugs
211 - Fix crash drawing pie charts with many segments.
213 - Fix crash when NUMERIC specifies an invalid format.
215 * PSPPIRE bug fixes and changes:
217 - On Windows, write the output file to the user's home directory
218 instead of the current directory, to better match user
221 - Some data editor fixes.
225 - Fix typo in BINOMIAL section of user manual (bug #25892).
227 Changes from 0.6.0 to 0.6.1:
229 * Statistical bug fixes:
231 - Report correct standardized regression coefficients in linear
232 regression output (bug #23567).
234 * Bug fixes that affect PSPP and PSPPIRE:
236 - Avoid crash with pie charts (bug #24014).
238 - Don't append % to count totals (bug #24003).
240 - Don't crash on bad input (bug #24031).
242 - Don't crash if "end data." is not left aligned (bug #24115).
244 - Change default workspace value to 64 MB, to avoid unnecessary
245 disk accesses on modern machines.
249 - Add ".sav" or ".por" suffix to filename when saving with Save_As
252 - Make it possible to reopen the output window on Windows (bug
255 - A POSIX regular expression library is now included and used
256 automatically if the host does not have one or has one that is
259 * Build fixes and changes:
261 - Work around bug in GSL that prevented build with recent GCC
262 versions without manually adding -fgnu89-inline to CFLAGS.
264 - Also warn about missing prerequisites as we encounter them (bug
267 - Distribute necessary files to allow users working from the
268 distributed tarball to configure with --enable-gui-tools.
270 - Append $(EXEEXT_FOR_BUILD) to output file name when building
271 q2c, fixing build problems on Windows.
273 - GSL 1.8 or later is now required.
275 - Build errors with --enable-relocatable were fixed.
277 * The German translations were removed, since native German speakers
278 found them too poor to be useful.
280 Changes from 0.4.0 to 0.6.0:
282 * The PSPP license is now version 3 or later of the GNU General
283 Public License. Previously, it was version 2 or later.
285 * PSPP now has a graphical interface, called PSPPIRE. This
286 interface allows you to enter data and variable definitions
287 interactively. Commands may be executed in syntax form, or by
288 using the interactive dialog boxes available from the dropdown
291 * A few sample syntax files are now included in the `examples'
294 * Numerous major and minor bugs have been fixed.
298 * The INSTALL file now reflects the details of how to install
299 PSPP. It is a tailored version of the generic installation
300 instructions, instead of a verbatim copy.
302 * iconv, which is ordinarily installed as part of a Unix-like
303 system, is now required. If you don't have it already, you can
304 install GNU libiconv (http://www.gnu.org/software/libiconv/).
306 * libxml2 and zlib are new optional dependencies. They are
307 required to use PSPP's support for reading Gnumeric files.
309 Statistical procedure changes:
311 * REGRESSION is a new procedure for fitting linear models to data
312 via least-squares estimation.
314 * NPAR TESTS is a new procedure for non-parametric tests. In this
315 release, it supports binomial and chi-square tests.
317 * RANK is a new procedure to rank variables. It supports numerous
320 * FREQUENCIES can now output histograms and pie charts. These
321 features were present in earlier releases, but not documented.
323 User interface changes:
325 * In many situations where PSPP once terminated with a fatal
326 error, PSPP now recovers and continues execution.
328 * PSPP is now able to start up and run even if it cannot find its
331 * Journaling of interactive commands to a disk file is now
332 implemented. By default, journaling is enabled, to a file named
333 `pspp.jnl' in the current directory. SET JOURNAL may be used to
336 * The use of `+' between syntax file names on the command line to
337 prevent the dictionary from being cleared between their
338 executions is no longer supported. All syntax files are now
339 executed as if `+' had been specified.
341 * The -d/--define and -u/--undef command line options are no
342 longer supported. Instead, use /usr/bin/env or shell primitives
343 to define or clear environment variables before invoking PSPP.
345 * If a syntax file named named `rc' is found in a configuration
346 directory (such as $HOME/.pspp), it is executed before any
347 syntax file specified on the command line. The -r or
348 --no-statrc command line option may be used to disable this
353 * Output configuration options have changed. Please refer to the
354 manual for a full description of the available options.
356 In consequence, you will need to reinstall your "devices" file.
357 "make install" will do this for you.
359 * Most error messages are now written to PSPP output files by
360 default. SET ERROR can be used to disable this behavior.
362 * When invoked interactively, PSPP now by default produces output
363 on the terminal, piping it through the "more" program.
364 Previously, by default output was written only to file
365 pspp.list. On most terminals, the page length used for output
366 automatically adapts to the terminal size, even if the terminal
371 - This driver now supports charts in output. Charts are written
372 as separate files that the main output file refers to. By
373 default, charts are written in PNG format to files named
374 pspp-1.png, pspp-2.png, and so on.
376 - Configurations are provided that use VT100 (and xterm)
377 line-drawing characters in tables. The option "-o list-vt100"
378 requests use of this device for output to pspp.list.
382 - The default paper size is now determined using the PAPERSIZE
383 environment variable, or the LC_PAPER locale category on
384 systems that support it. If these are not set, the default is
385 now A4, instead of US letter. To make US letter the default,
386 set PAPERSIZE to "letter" in your environment.
388 - Font metrics are now read from AFM files, instead of
389 Groff-format metrics files. PostScript fonts can now be
392 In consequence, you will need to install an AFM file for each
393 font used in PostScript output. "make install" will install
394 AFM files for the standard PostScript fonts, including the
395 ones that the PostScript driver uses by default.
397 - Standard paper sizes no longer need to be specified through a
398 configuration file. The "papersize" configuration file is no
399 longer needed, or supported.
401 - The PostScript prologue is no longer obtained from the
402 "ps-prologue" configuration file. This configuration file is
403 no longer needed, or supported.
407 - The HTML prologue is no longer obtained from the
408 "html-prologue" configuration file. This configuration file
409 is no longer needed, or supported.
411 Command language changes:
413 * The following commands are new:
415 - GET DATA, which currently supports reading Gnumeric files and
416 text data files. It will be extended later to read other
417 types of foreign data.
419 - CD, to change the current directory.
421 - INSERT, to execute a syntax file.
423 - DELETE VARIABLES, to remove variables from the active file
426 - ADD DOCUMENT, to add text to active file documents.
428 - CLOSE FILE HANDLE (a PSPP extension; see below).
430 - XEXPORT, a PSPP extension that is a transformation equivalent
433 * The following functions for transformation expressions are new:
435 - DATEDIFF, for computing the difference of two dates.
437 - DATESUM, for advancing a date by a specified duration.
439 - VALUELABEL, to obtain the value label for a value.
441 * PSPP now supports very long string variables (over 255 bytes
444 * MATCH FILES now supports the FIRST and LAST subcommands.
446 * Previous versions of PSPP prohibited using commands to both read and
447 write a single file at the same time. Now, PSPP allows this, and
448 the new version of the file atomically replaces the old version.
450 * The following commands are no longer available. They will be
451 re-implemented in a later release:
453 - CLEAR TRANSFORMATIONS
459 * The PROCESS IF command, which was deprecated, has been removed.
460 You may replace any usage of it by SELECT IF following
461 TEMPORARY, which has the same effect.
463 * The output format for variables created by VECTOR may now be
464 specified as part of the VECTOR syntax.
466 "Scratch files", a new PSPP extension:
468 A scratch file, like a system file, consists of a dictionary and
469 any number of cases. Small scratch files are stored in memory;
470 one that grows too large is written to disk. By default, any file
471 handle whose name begins with # is assumed to refer to a scratch
474 Scratch files can be used just about anywhere a system or portable
475 file can be used. Also, portable files are now allowed in most
476 places that system files were allowed in previous PSPP version.
478 A new CLOSE FILE HANDLE command allows the storage associated with
479 scratch files to be freed. It also allows file handles to be
480 reassigned to new files.
482 For more information on scratch files, refer to the "File Handles"
483 section in the PSPP manual. For specifics of what commands now
484 allow what kinds of files to be specified, refer to the
485 documentation on those particular commands.
489 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
490 translation, are now supported. Use FILE HANDLE to specify the
491 format of these files.
493 * Little-endian, big-endian, and VAX-endian formats are now
494 supported for integer binary formats when reading and writing
495 data files. The new RIB and WIB subcommands on the SET command
496 control endianness of integer data. The default is the host's
499 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
500 floating point binary formats when reading and writing data
501 files. The new RRB and WRB subcommands on the SET command
502 control the floating point format. The default is the host's
503 native floating point format.
505 * DATA LIST now supports the SKIP subcommand, to skip records at
506 the beginning of a file. For compatibility, DATA LIST now
507 treats N format as F format for FREE and LIST format input.
509 * The SAVE and XSAVE commands now support the UNSELECTED,
510 PERMISSIONS, NAMES, and MAP subcommands.
512 * The EXPORT command has been re-implemented to obtain better
513 results. Support for the UNSELECTED, DIGITS, and TYPE
514 subcommands has been added.
516 * For compatibility, PRINT now inserts a space at the beginning of
517 every output line, even lines that would otherwise be blank,
518 when OUTFILE is specified. (The behavior of WRITE is
521 * For compatibility, PRINT EJECT now inserts the digit `1' at the
522 beginning of each line that should begin a new page.
524 * For compatibility, WRITE now outputs the system-missing value as
525 a field filled with spaces. Binary formats are an exception.
526 (The behavior of PRINT is unchanged.)
530 * Input and output format descriptions have been rewritten. They
531 now precisely describe what is accepted on input and written on
534 * The descriptions of the PSPP system and portable file formats
535 have been extensively revised and improved.
537 For developers, the build system now requires Autoconf 2.60 and
540 Changes from 0.3.0 to 0.4.0:
542 Changes in build dependencies:
544 * The GNU Scientific Library (libgsl), version 1.6 or later, is
547 * libplot from GNU plotutils is optional. Without it, the new
548 graphing features will not work. If you do not have it
549 installed, you must run `configure' with --without-libplot.
551 * libgmp2 is no longer a dependency.
553 Newly implemented commands and statistical features:
555 * EXAMINE, including its graphing features.
557 * FREQUENCIES now supports percentiles.
565 * SORT CASES now sorts stably, that is, two cases with equal sort
566 criteria will be in the same relative order before and after the
569 * T-TEST (re-written).
571 * DATE and USE. These commands are parsed but otherwise ignored,
572 to enhance compatibility with certain command files that invoke
575 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
576 currently have no effect on PSPP output, but their values are
577 written to and read from system files and thus may affect
578 third-party software.
580 * SET EPOCH implemented.
582 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
585 * FILE HANDLE now supports custom tab widths.
587 Long variable names (and other identifiers) are now supported. Up
588 to the first 64 bytes of each identifier is significant. PSPP now
589 reads and writes system files compatible with SPSS version 12.
591 New --algorithm and --syntax command line options allow
592 SPSS-compatible or enhanced modes to be selected.
594 Support for transformation expressions has been rewritten and
595 significantly improved. Refer to the manual for details.
597 Calculation of moments (mean, standard deviation, kurtosis,
598 skewness) has been rewritten and should now be more accurate. In
599 --algorithm=enhanced mode moments may be more accurate than SPSS in
602 Numerous bugs have been fixed, too many to mention here. Many new
603 tests have been added, leading to the discovery and fixing of many
606 The ASCII output driver can now squeeze multiple blank lines into
609 Much of the code has been rewritten and refactored. It is now much
612 The FILE TYPE and REPEATING DATA commands have been disabled for
613 this release because their implementations were deemed too buggy to
614 be useful. They will be fixed and replaced in a future release.
616 New pspp-mode for Emacs (in pspp-mode.el).
618 Added rudimentary command-line completion for interactive input.
620 lib/julcal and lib/dcdflib are no longer used, so they have been
623 For developers, the build system now requires Autoconf 2.58 and
624 Automake 1.7. The included gettext has been updated to version
627 Some reports state that Texinfo 4.8, the latest version, may be
628 necessary to successfully format the documentation on some systems.
630 Version 0.3.0 changes since 0.2.3:
634 * Using alphanumeric variables in functions under AGGREGATE
637 * Under certain circumstances, the final case would be omitted
638 from the results of an AGGREGATE operation. Fixed.
640 * Undefined behavior was invoked by referencing a freed pointer
641 under certain circumstances. Fixed.
643 * A wrong record size was displayed when paging the active file to
646 * Not having enough temporary space for sorting caused a core
649 * Syntax errors in function descriptions on AGGREGATE caused core
652 * A null pointer was dereferenced, causing a core dump, when
653 PERCENTILES was specified on FREQUENCIES. This fixes the
654 problem, but PSPP still doesn't calculate percentiles.
656 * SORT always sorted in ascending order. Fixed.
658 * Some minor memory leaks in the expression parser were removed.
660 * Many assertions fixed for strict ANSI C compliance.
664 * SET ECHO ON now implemented, but turned off by default.
666 * PRINT specifier supported on END REPEAT.
670 * System libgmp2 library is used if installed instead of
671 unconditionally using the included libgmp2 subset.
673 * Extensive code cleanup, which continues.
675 * Added CORRELATIONS command parser, but not implemented.
677 Version 0.2.3 changes since 0.2.2:
681 * SPLIT FILE with a string variable caused a core dump. Fixed.
683 * Nested INCLUDEs didn't work. Fixed.
685 * The MATCH FILES procedure set the values of variables not present
686 to 0. It should have been SYSMIS. This is now fixed.
688 * The REMARK command was too aggressive about skipping lines. It
689 didn't like being the last command in a file.
691 * Comment parsing wasn't consistent with the rest of the code in its
692 idea of where one command ends and another starts. This meant
693 that sometimes commands would be mysteriously ignored. Thanks to
694 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
696 * The TABLE subcommand on MATCH FILES worked only erratically at
697 best. This fixes it. Thanks to Dr. Dirk Melcher
698 <BZN-mdksh@t-online.de> for reporting this bug.
700 * VARIABLE LABELS rejected a slash before the first variable
701 specification, contradicting the documentation. Thanks to Walter
702 M. Gray <graywm@northernc.on.ca> for reporting this bug.
704 * Because of an incorrect optimization in memory allocation,
705 CROSSTABS sometimes segfaulted when asked to output multiple
706 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
709 * CROSSTABS didn't display value labels for column and row
710 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
713 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
714 <BZN-mdksh@t-online.de> for reporting this bug.
716 * The TABLE subcommand on MATCH FILES worked only erratically at
717 best. This fixes it. Thanks to Dr. Dirk Melcher
718 <BZN-mdksh@t-online.de> for reporting this bug.
720 * VARIABLE LABELS rejected a slash before the first variable
721 specification, contradicting the documentation. Thanks to Walter
722 M. Gray <graywm@northernc.on.ca> for reporting this bug.
724 * Because of an incorrect optimization in memory allocation,
725 CROSSTABS sometimes segfaulted when asked to output multiple
726 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
729 * CROSSTABS didn't display value labels for column and row
730 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
733 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
734 <BZN-mdksh@t-online.de> for reporting this bug.
736 * MATCH FILES corrupted memory and dumped core on some syntax
739 * MATCH FILES should set numeric values not available to the
740 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
741 <BZN-mdksh@t-online.de> for reporting this bug.
743 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
744 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
748 * Some systems didn't like the way open_file was coded. Thanks to
749 Hankin <hankin@rogue.consultco.com> for pointing this out.
751 * The SAVE procedure didn't save long string variables properly.
752 Fixed by this patch. Thanks to Hankin
753 <hankin@rogue.consultco.com> for this patch.
755 * Minor documentation fixes for MATCH FILES.
757 Version 0.2.2 changes since 0.2.1:
761 * Fix behavior of PRINT SPACE for negative arguments.
763 * Fix reading some unusual system files.
765 * Fix LIST problems with very long variables. Thanks to Hankin
766 <hankin@dunno.com> for this bug report.
768 * Fix problems with some string format specifiers.
770 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
771 <BZN-mdksh@t-online.de> for reporting this bug.
773 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
774 Hankin <hankin@dunno.com> again on this one.
776 * Sometimes you may encounter a PSPP script that has to be
777 interpreted in interactive mode. Now you can use the -i flag to
780 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
781 `unused variable' warnings under gcc 2.7.2.3, fixing this will
786 * The files in gmp need the internationalization directory in
787 their include path. Thanks to OKUJI Yoshinori
788 <okuji@kuicr.kyoto-u.ac.jp> for pointing this out.
790 Version 0.2.1 changes since 0.2.0:
794 * Remember to include examples/ directory in distribution :-)
796 * Fixed gmp compile problems for some non-i386 architectures.
