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 - HOST has been updated to use more modern syntax.
46 - Most commands that work with data files now support a new
49 - MISSING VALUES can now assign missing values to long string
52 - ONEWAY: the POSTHOC subcommand is now implemented.
54 - The following new subcommands to NPAR TESTS have been implemented:
55 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
56 MCNEMAR, SIGN, WILCOXON, and RUNS
58 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
59 DPROMPT subcommands. The defaults are now fixed values.
61 - VALUE LABELS can now assign value labels to long string
64 * Other language changes:
66 - The new DATASET commands replace the "scratch file" PSPP
67 extension, which is no longer supported.
69 - Strings may now include arbitrary Unicode code points specified
70 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
71 code point U+1D11E, the musical G clef character, may be
72 expressed as U'1D11E'.
74 See the "Tokens" section in the PSPP manual for more information.
76 - In previous versions of PSPP, in a string expressed in
77 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
78 bytes in the locale encoding. In this version of PSPP, X'hh'
79 syntax always expresses bytes in UTF-8 encoding.
81 See the "Tokens" section in the PSPP manual for more information.
83 * PSPPIRE graphical user interface improvements:
85 - Added support for non-ASCII characters in strings, labels and
88 - A "Split Window" function is available, which makes it easier to
89 see different parts of a large data file.
91 - Data files can now be opened by specifing their name as the first
92 argument. This means that on a properly configured desktop, double
93 clicking on an icon will open the file.
97 - The new "cairo" output driver supports output in PostScript, PDF,
98 and SVG formats. Its functionality is a superset of that of the
99 "postscript" driver, which has been removed. You must have Cairo
100 and Pango installed to build the "cairo" driver.
102 - Charts are now produced with Cairo and Pango, instead of libplot.
103 Without them, the new graphing features will not work. If you do
104 not have Cairo and Pango installed, you must run `configure' with
107 - The plain text output driver now properly supports multibyte UTF-8
108 characters, including double-width characters and combining
111 - Output to OpenDocument format is now supported.
113 - The HTML output is much improved.
115 * The "pspp" program has a new option --batch (or -b) that selects
116 "batch" syntax mode. In previous versions of PSPP this syntax mode
117 was the default. Now a new "auto" syntax mode is the default. In
118 "auto" mode, PSPP interprets most syntax files correctly regardless
119 of their intended syntax mode.
121 See the "Syntax Variants" section in the PSPP manual for more
124 * The "pspp" program has a new option --syntax-encoding that
125 specifies the encoding for syntax files listed on the command line,
126 as well as the default encoding for syntax files included with
127 INCLUDE or INSERT. The default is to accept the system locale
128 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
129 one the system file uses.
131 See the documentation for the INSERT command in the PSPP manual for
134 * A new Perl module allows Perl programs to read and write PSPP
137 * A tutorial chapter has been added to the user manual.
139 Changes from 0.6.1 to 0.6.2:
143 - Dutch, thanks to Harry Thijssen.
145 - Brazilian Portuguese, thanks to Michel Boaventura.
147 Thanks for translations are also due to the coordinators at
148 translationproject.org.
150 * Statistical bug fixes:
152 - REGRESSION: Report correct standard error of the estimate (bug
155 - T-TEST: Report correct significance of paired sample T-test in
156 the common case (bug #26936) and corner cases. Thanks to Mike
157 Griffiths and Matej Cepl for reporting these bugs.
159 * Build fixes and changes:
161 - Fix build with GTK+ 2.17.4 and later.
163 - Make running "make" after running "configure" with different
164 settings reliably rebuild version.c.
166 - Cygwin and MinGW build fixes.
168 - Fixes for building with recent gnulib.
170 - The Makefile now honors two new variables, PSPP_LDFLAGS and
171 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
172 binaries, respectively. This makes building easier for some
175 - Fixes for "configure --enable-relocatable" (bug #25508).
177 * Data file bug fixes and changes:
179 - Fix reading text data files that contain a mix of white space
180 and commas. Now "a ,b" is treated as two fields containing "a"
181 and "b"; previously it was treated as three, with an empty field
184 - Fix writing corrupted .sav files on Windows.
186 - Fix writing variable labels longer than 252 bytes to save files.
187 Thanks to Robert Westlund for reporting this bug.
189 - Fix writing corrupted .por files (bug #26034).
191 - Fix reading .por files whose initial lines are not padded out
192 with spaces as expected.
194 - PSPP will no longer issue warnings about some .sav file records
195 or values that it does not understand. These warnings were
196 harmless, but needlessly alarmed some users.
198 - Fix crash reading empty string fields from PostgreSQL databases.
200 * Bug fixes that affect PSPP and PSPPIRE:
202 - Users may now control precision of output statistics. Instead
203 of hard coding the width and decimals of output numbers, respect
204 the default format in most instances. Counts are now normally
205 displayed with the format of the weight variable, if any.
207 - Fix crash when an INSERT command specifies the name of a file
208 that does not exist (bug #24569).
210 - Fix crash when CROSSTABS specifies a long-string variable (bugs
213 - Fix crash drawing pie charts with many segments.
215 - Fix crash when NUMERIC specifies an invalid format.
217 * PSPPIRE bug fixes and changes:
219 - On Windows, write the output file to the user's home directory
220 instead of the current directory, to better match user
223 - Some data editor fixes.
227 - Fix typo in BINOMIAL section of user manual (bug #25892).
229 Changes from 0.6.0 to 0.6.1:
231 * Statistical bug fixes:
233 - Report correct standardized regression coefficients in linear
234 regression output (bug #23567).
236 * Bug fixes that affect PSPP and PSPPIRE:
238 - Avoid crash with pie charts (bug #24014).
240 - Don't append % to count totals (bug #24003).
242 - Don't crash on bad input (bug #24031).
244 - Don't crash if "end data." is not left aligned (bug #24115).
246 - Change default workspace value to 64 MB, to avoid unnecessary
247 disk accesses on modern machines.
251 - Add ".sav" or ".por" suffix to filename when saving with Save_As
254 - Make it possible to reopen the output window on Windows (bug
257 - A POSIX regular expression library is now included and used
258 automatically if the host does not have one or has one that is
261 * Build fixes and changes:
263 - Work around bug in GSL that prevented build with recent GCC
264 versions without manually adding -fgnu89-inline to CFLAGS.
266 - Also warn about missing prerequisites as we encounter them (bug
269 - Distribute necessary files to allow users working from the
270 distributed tarball to configure with --enable-gui-tools.
272 - Append $(EXEEXT_FOR_BUILD) to output file name when building
273 q2c, fixing build problems on Windows.
275 - GSL 1.8 or later is now required.
277 - Build errors with --enable-relocatable were fixed.
279 * The German translations were removed, since native German speakers
280 found them too poor to be useful.
282 Changes from 0.4.0 to 0.6.0:
284 * The PSPP license is now version 3 or later of the GNU General
285 Public License. Previously, it was version 2 or later.
287 * PSPP now has a graphical interface, called PSPPIRE. This
288 interface allows you to enter data and variable definitions
289 interactively. Commands may be executed in syntax form, or by
290 using the interactive dialog boxes available from the dropdown
293 * A few sample syntax files are now included in the `examples'
296 * Numerous major and minor bugs have been fixed.
300 * The INSTALL file now reflects the details of how to install
301 PSPP. It is a tailored version of the generic installation
302 instructions, instead of a verbatim copy.
304 * iconv, which is ordinarily installed as part of a Unix-like
305 system, is now required. If you don't have it already, you can
306 install GNU libiconv (http://www.gnu.org/software/libiconv/).
308 * libxml2 and zlib are new optional dependencies. They are
309 required to use PSPP's support for reading Gnumeric files.
311 Statistical procedure changes:
313 * REGRESSION is a new procedure for fitting linear models to data
314 via least-squares estimation.
316 * NPAR TESTS is a new procedure for non-parametric tests. In this
317 release, it supports binomial and chi-square tests.
319 * RANK is a new procedure to rank variables. It supports numerous
322 * FREQUENCIES can now output histograms and pie charts. These
323 features were present in earlier releases, but not documented.
325 User interface changes:
327 * In many situations where PSPP once terminated with a fatal
328 error, PSPP now recovers and continues execution.
330 * PSPP is now able to start up and run even if it cannot find its
333 * Journaling of interactive commands to a disk file is now
334 implemented. By default, journaling is enabled, to a file named
335 `pspp.jnl' in the current directory. SET JOURNAL may be used to
338 * The use of `+' between syntax file names on the command line to
339 prevent the dictionary from being cleared between their
340 executions is no longer supported. All syntax files are now
341 executed as if `+' had been specified.
343 * The -d/--define and -u/--undef command line options are no
344 longer supported. Instead, use /usr/bin/env or shell primitives
345 to define or clear environment variables before invoking PSPP.
347 * If a syntax file named named `rc' is found in a configuration
348 directory (such as $HOME/.pspp), it is executed before any
349 syntax file specified on the command line. The -r or
350 --no-statrc command line option may be used to disable this
355 * Output configuration options have changed. Please refer to the
356 manual for a full description of the available options.
358 In consequence, you will need to reinstall your "devices" file.
359 "make install" will do this for you.
361 * Most error messages are now written to PSPP output files by
362 default. SET ERROR can be used to disable this behavior.
364 * When invoked interactively, PSPP now by default produces output
365 on the terminal, piping it through the "more" program.
366 Previously, by default output was written only to file
367 pspp.list. On most terminals, the page length used for output
368 automatically adapts to the terminal size, even if the terminal
373 - This driver now supports charts in output. Charts are written
374 as separate files that the main output file refers to. By
375 default, charts are written in PNG format to files named
376 pspp-1.png, pspp-2.png, and so on.
378 - Configurations are provided that use VT100 (and xterm)
379 line-drawing characters in tables. The option "-o list-vt100"
380 requests use of this device for output to pspp.list.
384 - The default paper size is now determined using the PAPERSIZE
385 environment variable, or the LC_PAPER locale category on
386 systems that support it. If these are not set, the default is
387 now A4, instead of US letter. To make US letter the default,
388 set PAPERSIZE to "letter" in your environment.
390 - Font metrics are now read from AFM files, instead of
391 Groff-format metrics files. PostScript fonts can now be
394 In consequence, you will need to install an AFM file for each
395 font used in PostScript output. "make install" will install
396 AFM files for the standard PostScript fonts, including the
397 ones that the PostScript driver uses by default.
399 - Standard paper sizes no longer need to be specified through a
400 configuration file. The "papersize" configuration file is no
401 longer needed, or supported.
403 - The PostScript prologue is no longer obtained from the
404 "ps-prologue" configuration file. This configuration file is
405 no longer needed, or supported.
409 - The HTML prologue is no longer obtained from the
410 "html-prologue" configuration file. This configuration file
411 is no longer needed, or supported.
413 Command language changes:
415 * The following commands are new:
417 - GET DATA, which currently supports reading Gnumeric files and
418 text data files. It will be extended later to read other
419 types of foreign data.
421 - CD, to change the current directory.
423 - INSERT, to execute a syntax file.
425 - DELETE VARIABLES, to remove variables from the active file
428 - ADD DOCUMENT, to add text to active file documents.
430 - CLOSE FILE HANDLE (a PSPP extension; see below).
432 - XEXPORT, a PSPP extension that is a transformation equivalent
435 * The following functions for transformation expressions are new:
437 - DATEDIFF, for computing the difference of two dates.
439 - DATESUM, for advancing a date by a specified duration.
441 - VALUELABEL, to obtain the value label for a value.
443 * PSPP now supports very long string variables (over 255 bytes
446 * MATCH FILES now supports the FIRST and LAST subcommands.
448 * Previous versions of PSPP prohibited using commands to both read and
449 write a single file at the same time. Now, PSPP allows this, and
450 the new version of the file atomically replaces the old version.
452 * The following commands are no longer available. They will be
453 re-implemented in a later release:
455 - CLEAR TRANSFORMATIONS
461 * The PROCESS IF command, which was deprecated, has been removed.
462 You may replace any usage of it by SELECT IF following
463 TEMPORARY, which has the same effect.
465 * The output format for variables created by VECTOR may now be
466 specified as part of the VECTOR syntax.
468 "Scratch files", a new PSPP extension:
470 A scratch file, like a system file, consists of a dictionary and
471 any number of cases. Small scratch files are stored in memory;
472 one that grows too large is written to disk. By default, any file
473 handle whose name begins with # is assumed to refer to a scratch
476 Scratch files can be used just about anywhere a system or portable
477 file can be used. Also, portable files are now allowed in most
478 places that system files were allowed in previous PSPP version.
480 A new CLOSE FILE HANDLE command allows the storage associated with
481 scratch files to be freed. It also allows file handles to be
482 reassigned to new files.
484 For more information on scratch files, refer to the "File Handles"
485 section in the PSPP manual. For specifics of what commands now
486 allow what kinds of files to be specified, refer to the
487 documentation on those particular commands.
491 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
492 translation, are now supported. Use FILE HANDLE to specify the
493 format of these files.
495 * Little-endian, big-endian, and VAX-endian formats are now
496 supported for integer binary formats when reading and writing
497 data files. The new RIB and WIB subcommands on the SET command
498 control endianness of integer data. The default is the host's
501 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
502 floating point binary formats when reading and writing data
503 files. The new RRB and WRB subcommands on the SET command
504 control the floating point format. The default is the host's
505 native floating point format.
507 * DATA LIST now supports the SKIP subcommand, to skip records at
508 the beginning of a file. For compatibility, DATA LIST now
509 treats N format as F format for FREE and LIST format input.
511 * The SAVE and XSAVE commands now support the UNSELECTED,
512 PERMISSIONS, NAMES, and MAP subcommands.
514 * The EXPORT command has been re-implemented to obtain better
515 results. Support for the UNSELECTED, DIGITS, and TYPE
516 subcommands has been added.
518 * For compatibility, PRINT now inserts a space at the beginning of
519 every output line, even lines that would otherwise be blank,
520 when OUTFILE is specified. (The behavior of WRITE is
523 * For compatibility, PRINT EJECT now inserts the digit `1' at the
524 beginning of each line that should begin a new page.
526 * For compatibility, WRITE now outputs the system-missing value as
527 a field filled with spaces. Binary formats are an exception.
528 (The behavior of PRINT is unchanged.)
532 * Input and output format descriptions have been rewritten. They
533 now precisely describe what is accepted on input and written on
536 * The descriptions of the PSPP system and portable file formats
537 have been extensively revised and improved.
539 For developers, the build system now requires Autoconf 2.60 and
542 Changes from 0.3.0 to 0.4.0:
544 Changes in build dependencies:
546 * The GNU Scientific Library (libgsl), version 1.6 or later, is
549 * libplot from GNU plotutils is optional. Without it, the new
550 graphing features will not work. If you do not have it
551 installed, you must run `configure' with --without-libplot.
553 * libgmp2 is no longer a dependency.
555 Newly implemented commands and statistical features:
557 * EXAMINE, including its graphing features.
559 * FREQUENCIES now supports percentiles.
567 * SORT CASES now sorts stably, that is, two cases with equal sort
568 criteria will be in the same relative order before and after the
571 * T-TEST (re-written).
573 * DATE and USE. These commands are parsed but otherwise ignored,
574 to enhance compatibility with certain command files that invoke
577 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
578 currently have no effect on PSPP output, but their values are
579 written to and read from system files and thus may affect
580 third-party software.
582 * SET EPOCH implemented.
584 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
587 * FILE HANDLE now supports custom tab widths.
589 Long variable names (and other identifiers) are now supported. Up
590 to the first 64 bytes of each identifier is significant. PSPP now
591 reads and writes system files compatible with SPSS version 12.
593 New --algorithm and --syntax command line options allow
594 SPSS-compatible or enhanced modes to be selected.
596 Support for transformation expressions has been rewritten and
597 significantly improved. Refer to the manual for details.
599 Calculation of moments (mean, standard deviation, kurtosis,
600 skewness) has been rewritten and should now be more accurate. In
601 --algorithm=enhanced mode moments may be more accurate than SPSS in
604 Numerous bugs have been fixed, too many to mention here. Many new
605 tests have been added, leading to the discovery and fixing of many
608 The ASCII output driver can now squeeze multiple blank lines into
611 Much of the code has been rewritten and refactored. It is now much
614 The FILE TYPE and REPEATING DATA commands have been disabled for
615 this release because their implementations were deemed too buggy to
616 be useful. They will be fixed and replaced in a future release.
618 New pspp-mode for Emacs (in pspp-mode.el).
620 Added rudimentary command-line completion for interactive input.
622 lib/julcal and lib/dcdflib are no longer used, so they have been
625 For developers, the build system now requires Autoconf 2.58 and
626 Automake 1.7. The included gettext has been updated to version
629 Some reports state that Texinfo 4.8, the latest version, may be
630 necessary to successfully format the documentation on some systems.
632 Version 0.3.0 changes since 0.2.3:
636 * Using alphanumeric variables in functions under AGGREGATE
639 * Under certain circumstances, the final case would be omitted
640 from the results of an AGGREGATE operation. Fixed.
642 * Undefined behavior was invoked by referencing a freed pointer
643 under certain circumstances. Fixed.
645 * A wrong record size was displayed when paging the active file to
648 * Not having enough temporary space for sorting caused a core
651 * Syntax errors in function descriptions on AGGREGATE caused core
654 * A null pointer was dereferenced, causing a core dump, when
655 PERCENTILES was specified on FREQUENCIES. This fixes the
656 problem, but PSPP still doesn't calculate percentiles.
658 * SORT always sorted in ascending order. Fixed.
660 * Some minor memory leaks in the expression parser were removed.
662 * Many assertions fixed for strict ANSI C compliance.
666 * SET ECHO ON now implemented, but turned off by default.
668 * PRINT specifier supported on END REPEAT.
672 * System libgmp2 library is used if installed instead of
673 unconditionally using the included libgmp2 subset.
675 * Extensive code cleanup, which continues.
677 * Added CORRELATIONS command parser, but not implemented.
679 Version 0.2.3 changes since 0.2.2:
683 * SPLIT FILE with a string variable caused a core dump. Fixed.
685 * Nested INCLUDEs didn't work. Fixed.
687 * The MATCH FILES procedure set the values of variables not present
688 to 0. It should have been SYSMIS. This is now fixed.
690 * The REMARK command was too aggressive about skipping lines. It
691 didn't like being the last command in a file.
693 * Comment parsing wasn't consistent with the rest of the code in its
694 idea of where one command ends and another starts. This meant
695 that sometimes commands would be mysteriously ignored. Thanks to
696 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
698 * The TABLE subcommand on MATCH FILES worked only erratically at
699 best. This fixes it. Thanks to Dr. Dirk Melcher
700 <BZN-mdksh@t-online.de> for reporting this bug.
702 * VARIABLE LABELS rejected a slash before the first variable
703 specification, contradicting the documentation. Thanks to Walter
704 M. Gray <graywm@northernc.on.ca> for reporting this bug.
706 * Because of an incorrect optimization in memory allocation,
707 CROSSTABS sometimes segfaulted when asked to output multiple
708 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
711 * CROSSTABS didn't display value labels for column and row
712 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
715 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
716 <BZN-mdksh@t-online.de> for reporting this bug.
718 * The TABLE subcommand on MATCH FILES worked only erratically at
719 best. This fixes it. Thanks to Dr. Dirk Melcher
720 <BZN-mdksh@t-online.de> for reporting this bug.
722 * VARIABLE LABELS rejected a slash before the first variable
723 specification, contradicting the documentation. Thanks to Walter
724 M. Gray <graywm@northernc.on.ca> for reporting this bug.
726 * Because of an incorrect optimization in memory allocation,
727 CROSSTABS sometimes segfaulted when asked to output multiple
728 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
731 * CROSSTABS didn't display value labels for column and row
732 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
735 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
736 <BZN-mdksh@t-online.de> for reporting this bug.
738 * MATCH FILES corrupted memory and dumped core on some syntax
741 * MATCH FILES should set numeric values not available to the
742 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
743 <BZN-mdksh@t-online.de> for reporting this bug.
745 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
746 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
750 * Some systems didn't like the way open_file was coded. Thanks to
751 Hankin <hankin@rogue.consultco.com> for pointing this out.
753 * The SAVE procedure didn't save long string variables properly.
754 Fixed by this patch. Thanks to Hankin
755 <hankin@rogue.consultco.com> for this patch.
757 * Minor documentation fixes for MATCH FILES.
759 Version 0.2.2 changes since 0.2.1:
763 * Fix behavior of PRINT SPACE for negative arguments.
765 * Fix reading some unusual system files.
767 * Fix LIST problems with very long variables. Thanks to Hankin
768 <hankin@dunno.com> for this bug report.
770 * Fix problems with some string format specifiers.
772 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
773 <BZN-mdksh@t-online.de> for reporting this bug.
775 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
776 Hankin <hankin@dunno.com> again on this one.
778 * Sometimes you may encounter a PSPP script that has to be
779 interpreted in interactive mode. Now you can use the -i flag to
782 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
783 `unused variable' warnings under gcc 2.7.2.3, fixing this will
788 * The files in gmp need the internationalization directory in
789 their include path. Thanks to OKUJI Yoshinori
790 <okuji@kuicr.kyoto-u.ac.jp> for pointing this out.
792 Version 0.2.1 changes since 0.2.0:
796 * Remember to include examples/ directory in distribution :-)
798 * Fixed gmp compile problems for some non-i386 architectures.
