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.
100 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
101 via using an "intelligent" application assistant dialog.
105 - The new "cairo" output driver supports output in PostScript, PDF,
106 and SVG formats. Its functionality is a superset of that of the
107 "postscript" driver, which has been removed. You must have Cairo
108 and Pango installed to build the "cairo" driver.
110 - Charts are now produced with Cairo and Pango, instead of libplot.
111 Without them, the new graphing features will not work. If you do
112 not have Cairo and Pango installed, you must run `configure' with
115 - The plain text output driver now properly supports multibyte UTF-8
116 characters, including double-width characters and combining
119 - Output to OpenDocument format is now supported.
121 - The HTML output is much improved.
123 * The "pspp" program has a new option --batch (or -b) that selects
124 "batch" syntax mode. In previous versions of PSPP this syntax mode
125 was the default. Now a new "auto" syntax mode is the default. In
126 "auto" mode, PSPP interprets most syntax files correctly regardless
127 of their intended syntax mode.
129 See the "Syntax Variants" section in the PSPP manual for more
132 * The "pspp" program has a new option --syntax-encoding that
133 specifies the encoding for syntax files listed on the command line,
134 as well as the default encoding for syntax files included with
135 INCLUDE or INSERT. The default is to accept the system locale
136 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
137 one the system file uses.
139 See the documentation for the INSERT command in the PSPP manual for
142 * Text data files that PRINT and WRITE creates now use the system
143 native line ends by default (CRLF on Windows, LF only elsewhere).
144 Use the new ENDS subcommand on FILE HANDLE to override the default.
146 * A new Perl module allows Perl programs to read and write PSPP
149 * A tutorial chapter has been added to the user manual.
151 Changes from 0.6.1 to 0.6.2:
155 - Dutch, thanks to Harry Thijssen.
157 - Brazilian Portuguese, thanks to Michel Boaventura.
159 Thanks for translations are also due to the coordinators at
160 translationproject.org.
162 * Statistical bug fixes:
164 - REGRESSION: Report correct standard error of the estimate (bug
167 - T-TEST: Report correct significance of paired sample T-test in
168 the common case (bug #26936) and corner cases. Thanks to Mike
169 Griffiths and Matej Cepl for reporting these bugs.
171 * Build fixes and changes:
173 - Fix build with GTK+ 2.17.4 and later.
175 - Make running "make" after running "configure" with different
176 settings reliably rebuild version.c.
178 - Cygwin and MinGW build fixes.
180 - Fixes for building with recent gnulib.
182 - The Makefile now honors two new variables, PSPP_LDFLAGS and
183 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
184 binaries, respectively. This makes building easier for some
187 - Fixes for "configure --enable-relocatable" (bug #25508).
189 * Data file bug fixes and changes:
191 - Fix reading text data files that contain a mix of white space
192 and commas. Now "a ,b" is treated as two fields containing "a"
193 and "b"; previously it was treated as three, with an empty field
196 - Fix writing corrupted .sav files on Windows.
198 - Fix writing variable labels longer than 252 bytes to save files.
199 Thanks to Robert Westlund for reporting this bug.
201 - Fix writing corrupted .por files (bug #26034).
203 - Fix reading .por files whose initial lines are not padded out
204 with spaces as expected.
206 - PSPP will no longer issue warnings about some .sav file records
207 or values that it does not understand. These warnings were
208 harmless, but needlessly alarmed some users.
210 - Fix crash reading empty string fields from PostgreSQL databases.
212 * Bug fixes that affect PSPP and PSPPIRE:
214 - Users may now control precision of output statistics. Instead
215 of hard coding the width and decimals of output numbers, respect
216 the default format in most instances. Counts are now normally
217 displayed with the format of the weight variable, if any.
219 - Fix crash when an INSERT command specifies the name of a file
220 that does not exist (bug #24569).
222 - Fix crash when CROSSTABS specifies a long-string variable (bugs
225 - Fix crash drawing pie charts with many segments.
227 - Fix crash when NUMERIC specifies an invalid format.
229 * PSPPIRE bug fixes and changes:
231 - On Windows, write the output file to the user's home directory
232 instead of the current directory, to better match user
235 - Some data editor fixes.
239 - Fix typo in BINOMIAL section of user manual (bug #25892).
241 Changes from 0.6.0 to 0.6.1:
243 * Statistical bug fixes:
245 - Report correct standardized regression coefficients in linear
246 regression output (bug #23567).
248 * Bug fixes that affect PSPP and PSPPIRE:
250 - Avoid crash with pie charts (bug #24014).
252 - Don't append % to count totals (bug #24003).
254 - Don't crash on bad input (bug #24031).
256 - Don't crash if "end data." is not left aligned (bug #24115).
258 - Change default workspace value to 64 MB, to avoid unnecessary
259 disk accesses on modern machines.
263 - Add ".sav" or ".por" suffix to filename when saving with Save_As
266 - Make it possible to reopen the output window on Windows (bug
269 - A POSIX regular expression library is now included and used
270 automatically if the host does not have one or has one that is
273 * Build fixes and changes:
275 - Work around bug in GSL that prevented build with recent GCC
276 versions without manually adding -fgnu89-inline to CFLAGS.
278 - Also warn about missing prerequisites as we encounter them (bug
281 - Distribute necessary files to allow users working from the
282 distributed tarball to configure with --enable-gui-tools.
284 - Append $(EXEEXT_FOR_BUILD) to output file name when building
285 q2c, fixing build problems on Windows.
287 - GSL 1.8 or later is now required.
289 - Build errors with --enable-relocatable were fixed.
291 * The German translations were removed, since native German speakers
292 found them too poor to be useful.
294 Changes from 0.4.0 to 0.6.0:
296 * The PSPP license is now version 3 or later of the GNU General
297 Public License. Previously, it was version 2 or later.
299 * PSPP now has a graphical interface, called PSPPIRE. This
300 interface allows you to enter data and variable definitions
301 interactively. Commands may be executed in syntax form, or by
302 using the interactive dialog boxes available from the dropdown
305 * A few sample syntax files are now included in the `examples'
308 * Numerous major and minor bugs have been fixed.
312 * The INSTALL file now reflects the details of how to install
313 PSPP. It is a tailored version of the generic installation
314 instructions, instead of a verbatim copy.
316 * iconv, which is ordinarily installed as part of a Unix-like
317 system, is now required. If you don't have it already, you can
318 install GNU libiconv (http://www.gnu.org/software/libiconv/).
320 * libxml2 and zlib are new optional dependencies. They are
321 required to use PSPP's support for reading Gnumeric files.
323 Statistical procedure changes:
325 * REGRESSION is a new procedure for fitting linear models to data
326 via least-squares estimation.
328 * NPAR TESTS is a new procedure for non-parametric tests. In this
329 release, it supports binomial and chi-square tests.
331 * RANK is a new procedure to rank variables. It supports numerous
334 * FREQUENCIES can now output histograms and pie charts. These
335 features were present in earlier releases, but not documented.
337 User interface changes:
339 * In many situations where PSPP once terminated with a fatal
340 error, PSPP now recovers and continues execution.
342 * PSPP is now able to start up and run even if it cannot find its
345 * Journaling of interactive commands to a disk file is now
346 implemented. By default, journaling is enabled, to a file named
347 `pspp.jnl' in the current directory. SET JOURNAL may be used to
350 * The use of `+' between syntax file names on the command line to
351 prevent the dictionary from being cleared between their
352 executions is no longer supported. All syntax files are now
353 executed as if `+' had been specified.
355 * The -d/--define and -u/--undef command line options are no
356 longer supported. Instead, use /usr/bin/env or shell primitives
357 to define or clear environment variables before invoking PSPP.
359 * If a syntax file named named `rc' is found in a configuration
360 directory (such as $HOME/.pspp), it is executed before any
361 syntax file specified on the command line. The -r or
362 --no-statrc command line option may be used to disable this
367 * Output configuration options have changed. Please refer to the
368 manual for a full description of the available options.
370 In consequence, you will need to reinstall your "devices" file.
371 "make install" will do this for you.
373 * Most error messages are now written to PSPP output files by
374 default. SET ERROR can be used to disable this behavior.
376 * When invoked interactively, PSPP now by default produces output
377 on the terminal, piping it through the "more" program.
378 Previously, by default output was written only to file
379 pspp.list. On most terminals, the page length used for output
380 automatically adapts to the terminal size, even if the terminal
385 - This driver now supports charts in output. Charts are written
386 as separate files that the main output file refers to. By
387 default, charts are written in PNG format to files named
388 pspp-1.png, pspp-2.png, and so on.
390 - Configurations are provided that use VT100 (and xterm)
391 line-drawing characters in tables. The option "-o list-vt100"
392 requests use of this device for output to pspp.list.
396 - The default paper size is now determined using the PAPERSIZE
397 environment variable, or the LC_PAPER locale category on
398 systems that support it. If these are not set, the default is
399 now A4, instead of US letter. To make US letter the default,
400 set PAPERSIZE to "letter" in your environment.
402 - Font metrics are now read from AFM files, instead of
403 Groff-format metrics files. PostScript fonts can now be
406 In consequence, you will need to install an AFM file for each
407 font used in PostScript output. "make install" will install
408 AFM files for the standard PostScript fonts, including the
409 ones that the PostScript driver uses by default.
411 - Standard paper sizes no longer need to be specified through a
412 configuration file. The "papersize" configuration file is no
413 longer needed, or supported.
415 - The PostScript prologue is no longer obtained from the
416 "ps-prologue" configuration file. This configuration file is
417 no longer needed, or supported.
421 - The HTML prologue is no longer obtained from the
422 "html-prologue" configuration file. This configuration file
423 is no longer needed, or supported.
425 Command language changes:
427 * The following commands are new:
429 - GET DATA, which currently supports reading Gnumeric files and
430 text data files. It will be extended later to read other
431 types of foreign data.
433 - CD, to change the current directory.
435 - INSERT, to execute a syntax file.
437 - DELETE VARIABLES, to remove variables from the active file
440 - ADD DOCUMENT, to add text to active file documents.
442 - CLOSE FILE HANDLE (a PSPP extension; see below).
444 - XEXPORT, a PSPP extension that is a transformation equivalent
447 * The following functions for transformation expressions are new:
449 - DATEDIFF, for computing the difference of two dates.
451 - DATESUM, for advancing a date by a specified duration.
453 - VALUELABEL, to obtain the value label for a value.
455 * PSPP now supports very long string variables (over 255 bytes
458 * MATCH FILES now supports the FIRST and LAST subcommands.
460 * Previous versions of PSPP prohibited using commands to both read and
461 write a single file at the same time. Now, PSPP allows this, and
462 the new version of the file atomically replaces the old version.
464 * The following commands are no longer available. They will be
465 re-implemented in a later release:
467 - CLEAR TRANSFORMATIONS
473 * The PROCESS IF command, which was deprecated, has been removed.
474 You may replace any usage of it by SELECT IF following
475 TEMPORARY, which has the same effect.
477 * The output format for variables created by VECTOR may now be
478 specified as part of the VECTOR syntax.
480 "Scratch files", a new PSPP extension:
482 A scratch file, like a system file, consists of a dictionary and
483 any number of cases. Small scratch files are stored in memory;
484 one that grows too large is written to disk. By default, any file
485 handle whose name begins with # is assumed to refer to a scratch
488 Scratch files can be used just about anywhere a system or portable
489 file can be used. Also, portable files are now allowed in most
490 places that system files were allowed in previous PSPP version.
492 A new CLOSE FILE HANDLE command allows the storage associated with
493 scratch files to be freed. It also allows file handles to be
494 reassigned to new files.
496 For more information on scratch files, refer to the "File Handles"
497 section in the PSPP manual. For specifics of what commands now
498 allow what kinds of files to be specified, refer to the
499 documentation on those particular commands.
503 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
504 translation, are now supported. Use FILE HANDLE to specify the
505 format of these files.
507 * Little-endian, big-endian, and VAX-endian formats are now
508 supported for integer binary formats when reading and writing
509 data files. The new RIB and WIB subcommands on the SET command
510 control endianness of integer data. The default is the host's
513 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
514 floating point binary formats when reading and writing data
515 files. The new RRB and WRB subcommands on the SET command
516 control the floating point format. The default is the host's
517 native floating point format.
519 * DATA LIST now supports the SKIP subcommand, to skip records at
520 the beginning of a file. For compatibility, DATA LIST now
521 treats N format as F format for FREE and LIST format input.
523 * The SAVE and XSAVE commands now support the UNSELECTED,
524 PERMISSIONS, NAMES, and MAP subcommands.
526 * The EXPORT command has been re-implemented to obtain better
527 results. Support for the UNSELECTED, DIGITS, and TYPE
528 subcommands has been added.
530 * For compatibility, PRINT now inserts a space at the beginning of
531 every output line, even lines that would otherwise be blank,
532 when OUTFILE is specified. (The behavior of WRITE is
535 * For compatibility, PRINT EJECT now inserts the digit `1' at the
536 beginning of each line that should begin a new page.
538 * For compatibility, WRITE now outputs the system-missing value as
539 a field filled with spaces. Binary formats are an exception.
540 (The behavior of PRINT is unchanged.)
544 * Input and output format descriptions have been rewritten. They
545 now precisely describe what is accepted on input and written on
548 * The descriptions of the PSPP system and portable file formats
549 have been extensively revised and improved.
551 For developers, the build system now requires Autoconf 2.60 and
554 Changes from 0.3.0 to 0.4.0:
556 Changes in build dependencies:
558 * The GNU Scientific Library (libgsl), version 1.6 or later, is
561 * libplot from GNU plotutils is optional. Without it, the new
562 graphing features will not work. If you do not have it
563 installed, you must run `configure' with --without-libplot.
565 * libgmp2 is no longer a dependency.
567 Newly implemented commands and statistical features:
569 * EXAMINE, including its graphing features.
571 * FREQUENCIES now supports percentiles.
579 * SORT CASES now sorts stably, that is, two cases with equal sort
580 criteria will be in the same relative order before and after the
583 * T-TEST (re-written).
585 * DATE and USE. These commands are parsed but otherwise ignored,
586 to enhance compatibility with certain command files that invoke
589 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
590 currently have no effect on PSPP output, but their values are
591 written to and read from system files and thus may affect
592 third-party software.
594 * SET EPOCH implemented.
596 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
599 * FILE HANDLE now supports custom tab widths.
601 Long variable names (and other identifiers) are now supported. Up
602 to the first 64 bytes of each identifier is significant. PSPP now
603 reads and writes system files compatible with SPSS version 12.
605 New --algorithm and --syntax command line options allow
606 SPSS-compatible or enhanced modes to be selected.
608 Support for transformation expressions has been rewritten and
609 significantly improved. Refer to the manual for details.
611 Calculation of moments (mean, standard deviation, kurtosis,
612 skewness) has been rewritten and should now be more accurate. In
613 --algorithm=enhanced mode moments may be more accurate than SPSS in
616 Numerous bugs have been fixed, too many to mention here. Many new
617 tests have been added, leading to the discovery and fixing of many
620 The ASCII output driver can now squeeze multiple blank lines into
623 Much of the code has been rewritten and refactored. It is now much
626 The FILE TYPE and REPEATING DATA commands have been disabled for
627 this release because their implementations were deemed too buggy to
628 be useful. They will be fixed and replaced in a future release.
630 New pspp-mode for Emacs (in pspp-mode.el).
632 Added rudimentary command-line completion for interactive input.
634 lib/julcal and lib/dcdflib are no longer used, so they have been
637 For developers, the build system now requires Autoconf 2.58 and
638 Automake 1.7. The included gettext has been updated to version
641 Some reports state that Texinfo 4.8, the latest version, may be
642 necessary to successfully format the documentation on some systems.
644 Version 0.3.0 changes since 0.2.3:
648 * Using alphanumeric variables in functions under AGGREGATE
651 * Under certain circumstances, the final case would be omitted
652 from the results of an AGGREGATE operation. Fixed.
654 * Undefined behavior was invoked by referencing a freed pointer
655 under certain circumstances. Fixed.
657 * A wrong record size was displayed when paging the active file to
660 * Not having enough temporary space for sorting caused a core
663 * Syntax errors in function descriptions on AGGREGATE caused core
666 * A null pointer was dereferenced, causing a core dump, when
667 PERCENTILES was specified on FREQUENCIES. This fixes the
668 problem, but PSPP still doesn't calculate percentiles.
670 * SORT always sorted in ascending order. Fixed.
672 * Some minor memory leaks in the expression parser were removed.
674 * Many assertions fixed for strict ANSI C compliance.
678 * SET ECHO ON now implemented, but turned off by default.
680 * PRINT specifier supported on END REPEAT.
684 * System libgmp2 library is used if installed instead of
685 unconditionally using the included libgmp2 subset.
687 * Extensive code cleanup, which continues.
689 * Added CORRELATIONS command parser, but not implemented.
691 Version 0.2.3 changes since 0.2.2:
695 * SPLIT FILE with a string variable caused a core dump. Fixed.
697 * Nested INCLUDEs didn't work. Fixed.
699 * The MATCH FILES procedure set the values of variables not present
700 to 0. It should have been SYSMIS. This is now fixed.
702 * The REMARK command was too aggressive about skipping lines. It
703 didn't like being the last command in a file.
705 * Comment parsing wasn't consistent with the rest of the code in its
706 idea of where one command ends and another starts. This meant
707 that sometimes commands would be mysteriously ignored. Thanks to
708 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
710 * The TABLE subcommand on MATCH FILES worked only erratically at
711 best. This fixes it. Thanks to Dr. Dirk Melcher
712 <BZN-mdksh@t-online.de> for reporting this bug.
714 * VARIABLE LABELS rejected a slash before the first variable
715 specification, contradicting the documentation. Thanks to Walter
716 M. Gray <graywm@northernc.on.ca> for reporting this bug.
718 * Because of an incorrect optimization in memory allocation,
719 CROSSTABS sometimes segfaulted when asked to output multiple
720 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
723 * CROSSTABS didn't display value labels for column and row
724 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
727 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
728 <BZN-mdksh@t-online.de> for reporting this bug.
730 * The TABLE subcommand on MATCH FILES worked only erratically at
731 best. This fixes it. Thanks to Dr. Dirk Melcher
732 <BZN-mdksh@t-online.de> for reporting this bug.
734 * VARIABLE LABELS rejected a slash before the first variable
735 specification, contradicting the documentation. Thanks to Walter
736 M. Gray <graywm@northernc.on.ca> for reporting this bug.
738 * Because of an incorrect optimization in memory allocation,
739 CROSSTABS sometimes segfaulted when asked to output multiple
740 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
743 * CROSSTABS didn't display value labels for column and row
744 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
747 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
748 <BZN-mdksh@t-online.de> for reporting this bug.
750 * MATCH FILES corrupted memory and dumped core on some syntax
753 * MATCH FILES should set numeric values not available to the
754 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
755 <BZN-mdksh@t-online.de> for reporting this bug.
757 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
758 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
762 * Some systems didn't like the way open_file was coded. Thanks to
763 Hankin <hankin@rogue.consultco.com> for pointing this out.
765 * The SAVE procedure didn't save long string variables properly.
766 Fixed by this patch. Thanks to Hankin
767 <hankin@rogue.consultco.com> for this patch.
769 * Minor documentation fixes for MATCH FILES.
771 Version 0.2.2 changes since 0.2.1:
775 * Fix behavior of PRINT SPACE for negative arguments.
777 * Fix reading some unusual system files.
779 * Fix LIST problems with very long variables. Thanks to Hankin
780 <hankin@dunno.com> for this bug report.
782 * Fix problems with some string format specifiers.
784 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
785 <BZN-mdksh@t-online.de> for reporting this bug.
787 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
788 Hankin <hankin@dunno.com> again on this one.
790 * Sometimes you may encounter a PSPP script that has to be
791 interpreted in interactive mode. Now you can use the -i flag to
794 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
795 `unused variable' warnings under gcc 2.7.2.3, fixing this will
