5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
7 Changes from 0.7.3 to 0.7.7:
9 * The "pspp" program has a new option --batch (or -b) that selects
10 "batch" syntax mode. In previous versions of PSPP this syntax mode
11 was the default. Now a new "auto" syntax mode is the default. In
12 "auto" mode, PSPP interprets most syntax files correctly regardless
13 of their intended syntax mode.
15 See the "Syntax Variants" section in the PSPP manual for more
18 * The "pspp" program has a new option --syntax-encoding that
19 specifies the encoding for syntax files listed on the command line,
20 as well as the default encoding for syntax files included with
21 INCLUDE or INSERT. The default is to accept the system locale
22 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
23 one the system file uses.
25 See the documentation for the INSERT command in the PSPP manual for
28 * The INCLUDE and INSERT commands now support the ENCODING subcommand
29 to specify the encoding for the included syntax file.
31 * Strings may now include arbitrary Unicode code points specified in
32 hexadecimal, using the syntax U'hhhh'. For example, Unicode code
33 point U+1D11E, the musical G clef character, may be expressed as
36 See the "Tokens" section in the PSPP manual for more information.
38 * In previous versions of PSPP, in a string expressed in hexadecimal
39 with X'hh' syntax, the hexadecimal digits expressed bytes in the
40 locale encoding. In this version of PSPP, X'hh' syntax always
41 expresses bytes in UTF-8 encoding.
43 See the "Tokens" section in the PSPP manual for more information.
45 * The DO REPEAT command has been reimplemented. The most prominent
46 change is that when a DO REPEAT block contains an INCLUDE or INSERT
47 command, substitutions are not applied to the included file.
49 See the "DO REPEAT" section in the PSPP manual for more information.
51 * NPAR TESTS now supports the /KRUSKAL-WALLIS and /RUNS subcommands.
53 * AUTORECODE now supports the /GROUP subcommand.
55 * The MRSETS command is now implemented.
57 * SAVE TRANSLATE is now implemented, with initial support for saving
58 data in comma-separated value and tab-delimited formats.
60 * The PRESERVE and RESTORE commands are now implemented.
62 * The HOST command has been updated to use more modern syntax.
64 * The SET and SHOW commands no longer support the ENDCMD, NULLINE,
65 PROMPT, CPROMPT, and DPROMPT subcommands. The defaults are now the
66 only supported values.
68 Changes from 0.7.2 to 0.7.3:
70 * Charts are now produced with Cairo and Pango, instead of libplot.
71 Without them, the new graphing features will not work. If you do
72 not have Cairo and Pango installed, you must run `configure' with
75 * The new "cairo" output driver supports output in PostScript, PDF,
76 and SVG formats. Its functionality is a superset of that of the
77 "postscript" driver, which has been removed. You must have Cairo
78 and Pango installed to build the "cairo" driver.
80 Changes from 0.7.1 to 0.7.2:
82 * Updated Perl module interface.
84 * Value labels for long string variables are now supported.
86 * Missing values for long string variables are now supported.
88 Changes from 0.7.0 to 0.7.1:
90 * Added a perl module to facilitate reading and writing of pspp system
91 files from perl programs.
93 Changes from 0.6.2-pre6 to 0.7.0:
95 * Custom variable and data file attributes are now supported.
96 Commands VARIABLE ATTRIBUTE and DATAFILE ATTRIBUTE have been added
97 for setting and clear attributes. Support for attributes has also
98 been added to commands that read and write system files, such as
99 SAVE and GET, as well as to the DISPLAY command.
101 * Numererous improvements to the Graphical User Interface have
102 made. Notable improvements include:
104 - Non-Ascii characters in strings, labels and variable names are
107 - A "Split Window" function is available, which makes it easier to
108 see different parts of a large data file.
110 - Data files can now be opened by specifing their name as the first
111 argument. This means that on a properly configured desktop, double
112 clicking on an icon will open the file.
115 * New statistical procedures:
120 NPAR TESTS now supports the WILCOXON and SIGN subcommands.
122 The CROSSTABS command has been completely re-implemented to fix numerous bugs.
124 * Three new commands to combine data files have been added: MATCH FILES,
125 UPDATE and ADD FILES.
127 * A tutorial chapter has been added to the user manual.
129 Changes from 0.6.1 to 0.6.2
133 - Dutch, thanks to Harry Thijssen.
135 - Brazilian Portuguese, thanks to Michel Boaventura.
137 Thanks for translations are also due to the coordinators at
138 translationproject.org.
140 * Statistical bug fixes:
142 - REGRESSION: Report correct standard error of the estimate (bug
145 - T-TEST: Report correct significance of paired sample T-test in
146 the common case (bug #26936) and corner cases. Thanks to Mike
147 Griffiths and Matej Cepl for reporting these bugs.
149 * Build fixes and changes:
151 - Fix build with GTK+ 2.17.4 and later.
153 - Make running "make" after running "configure" with different
154 settings reliably rebuild version.c.
156 - Cygwin and MinGW build fixes.
158 - Fixes for building with recent gnulib.
160 - The Makefile now honors two new variables, PSPP_LDFLAGS and
161 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
162 binaries, respectively. This makes building easier for some
165 - Fixes for "configure --enable-relocatable" (bug #25508).
167 * Data file bug fixes and changes:
169 - Fix reading text data files that contain a mix of white space
170 and commas. Now "a ,b" is treated as two fields containing "a"
171 and "b"; previously it was treated as three, with an empty field
174 - Fix writing corrupted .sav files on Windows.
176 - Fix writing variable labels longer than 252 bytes to save files.
177 Thanks to Robert Westlund for reporting this bug.
179 - Fix writing corrupted .por files (bug #26034).
181 - Fix reading .por files whose initial lines are not padded out
182 with spaces as expected.
184 - PSPP will no longer issue warnings about some .sav file records
185 or values that it does not understand. These warnings were
186 harmless, but needlessly alarmed some users.
188 - Fix crash reading empty string fields from PostgreSQL databases.
190 * Bug fixes that affect PSPP and PSPPIRE:
192 - Users may now control precision of output statistics. Instead
193 of hard coding the width and decimals of output numbers, respect
194 the default format in most instances. Counts are now normally
195 displayed with the format of the weight variable, if any.
197 - Fix crash when an INSERT command specifies the name of a file
198 that does not exist (bug #24569).
200 - Fix crash when CROSSTABS specifies a long-string variable (bugs
203 - Fix crash drawing pie charts with many segments.
205 - Fix crash when NUMERIC specifies an invalid format.
207 * PSPPIRE bug fixes and changes:
209 - On Windows, write the output file to the user's home directory
210 instead of the current directory, to better match user
213 - Some data editor fixes.
217 - Fix typo in BINOMIAL section of user manual (bug #25892).
219 Changes from 0.6.0 to 0.6.1:
221 * Statistical bug fixes:
223 - Report correct standardized regression coefficients in linear
224 regression output (bug #23567).
226 * Bug fixes that affect PSPP and PSPPIRE:
228 - Avoid crash with pie charts (bug #24014).
230 - Don't append % to count totals (bug #24003).
232 - Don't crash on bad input (bug #24031).
234 - Don't crash if "end data." is not left aligned (bug #24115).
236 - Change default workspace value to 64 MB, to avoid unnecessary
237 disk accesses on modern machines.
241 - Add ".sav" or ".por" suffix to filename when saving with Save_As
244 - Make it possible to reopen the output window on Windows (bug
247 - A POSIX regular expression library is now included and used
248 automatically if the host does not have one or has one that is
251 * Build fixes and changes:
253 - Work around bug in GSL that prevented build with recent GCC
254 versions without manually adding -fgnu89-inline to CFLAGS.
256 - Also warn about missing prerequisites as we encounter them (bug
259 - Distribute necessary files to allow users working from the
260 distributed tarball to configure with --enable-gui-tools.
262 - Append $(EXEEXT_FOR_BUILD) to output file name when building
263 q2c, fixing build problems on Windows.
265 - GSL 1.8 or later is now required.
267 - Build errors with --enable-relocatable were fixed.
269 * The German translations were removed, since native German speakers
270 found them too poor to be useful.
272 Changes from 0.4.0 to 0.6.0:
274 * The PSPP license is now version 3 or later of the GNU General
275 Public License. Previously, it was version 2 or later.
277 * PSPP now has a graphical interface, called PSPPIRE. This
278 interface allows you to enter data and variable definitions
279 interactively. Commands may be executed in syntax form, or by
280 using the interactive dialog boxes available from the dropdown
283 * A few sample syntax files are now included in the `examples'
286 * Numerous major and minor bugs have been fixed.
290 * The INSTALL file now reflects the details of how to install
291 PSPP. It is a tailored version of the generic installation
292 instructions, instead of a verbatim copy.
294 * iconv, which is ordinarily installed as part of a Unix-like
295 system, is now required. If you don't have it already, you can
296 install GNU libiconv (http://www.gnu.org/software/libiconv/).
298 * libxml2 and zlib are new optional dependencies. They are
299 required to use PSPP's support for reading Gnumeric files.
301 Statistical procedure changes:
303 * REGRESSION is a new procedure for fitting linear models to data
304 via least-squares estimation.
306 * NPAR TESTS is a new procedure for non-parametric tests. In this
307 release, it supports binomial and chi-square tests.
309 * RANK is a new procedure to rank variables. It supports numerous
312 * FREQUENCIES can now output histograms and pie charts. These
313 features were present in earlier releases, but not documented.
315 User interface changes:
317 * In many situations where PSPP once terminated with a fatal
318 error, PSPP now recovers and continues execution.
320 * PSPP is now able to start up and run even if it cannot find its
323 * Journaling of interactive commands to a disk file is now
324 implemented. By default, journaling is enabled, to a file named
325 `pspp.jnl' in the current directory. SET JOURNAL may be used to
328 * The use of `+' between syntax file names on the command line to
329 prevent the dictionary from being cleared between their
330 executions is no longer supported. All syntax files are now
331 executed as if `+' had been specified.
333 * The -d/--define and -u/--undef command line options are no
334 longer supported. Instead, use /usr/bin/env or shell primitives
335 to define or clear environment variables before invoking PSPP.
337 * If a syntax file named named `rc' is found in a configuration
338 directory (such as $HOME/.pspp), it is executed before any
339 syntax file specified on the command line. The -r or
340 --no-statrc command line option may be used to disable this
345 * Output configuration options have changed. Please refer to the
346 manual for a full description of the available options.
348 In consequence, you will need to reinstall your "devices" file.
349 "make install" will do this for you.
351 * Most error messages are now written to PSPP output files by
352 default. SET ERROR can be used to disable this behavior.
354 * When invoked interactively, PSPP now by default produces output
355 on the terminal, piping it through the "more" program.
356 Previously, by default output was written only to file
357 pspp.list. On most terminals, the page length used for output
358 automatically adapts to the terminal size, even if the terminal
363 - This driver now supports charts in output. Charts are written
364 as separate files that the main output file refers to. By
365 default, charts are written in PNG format to files named
366 pspp-1.png, pspp-2.png, and so on.
368 - Configurations are provided that use VT100 (and xterm)
369 line-drawing characters in tables. The option "-o list-vt100"
370 requests use of this device for output to pspp.list.
374 - The default paper size is now determined using the PAPERSIZE
375 environment variable, or the LC_PAPER locale category on
376 systems that support it. If these are not set, the default is
377 now A4, instead of US letter. To make US letter the default,
378 set PAPERSIZE to "letter" in your environment.
380 - Font metrics are now read from AFM files, instead of
381 Groff-format metrics files. PostScript fonts can now be
384 In consequence, you will need to install an AFM file for each
385 font used in PostScript output. "make install" will install
386 AFM files for the standard PostScript fonts, including the
387 ones that the PostScript driver uses by default.
389 - Standard paper sizes no longer need to be specified through a
390 configuration file. The "papersize" configuration file is no
391 longer needed, or supported.
393 - The PostScript prologue is no longer obtained from the
394 "ps-prologue" configuration file. This configuration file is
395 no longer needed, or supported.
399 - The HTML prologue is no longer obtained from the
400 "html-prologue" configuration file. This configuration file
401 is no longer needed, or supported.
403 Command language changes:
405 * The following commands are new:
407 - GET DATA, which currently supports reading Gnumeric files and
408 text data files. It will be extended later to read other
409 types of foreign data.
411 - CD, to change the current directory.
413 - INSERT, to execute a syntax file.
415 - DELETE VARIABLES, to remove variables from the active file
418 - ADD DOCUMENT, to add text to active file documents.
420 - CLOSE FILE HANDLE (a PSPP extension; see below).
422 - XEXPORT, a PSPP extension that is a transformation equivalent
425 * The following functions for transformation expressions are new:
427 - DATEDIFF, for computing the difference of two dates.
429 - DATESUM, for advancing a date by a specified duration.
431 - VALUELABEL, to obtain the value label for a value.
433 * PSPP now supports very long string variables (over 255 bytes
436 * MATCH FILES now supports the FIRST and LAST subcommands.
438 * Previous versions of PSPP prohibited using commands to both read and
439 write a single file at the same time. Now, PSPP allows this, and
440 the new version of the file atomically replaces the old version.
442 * The following commands are no longer available. They will be
443 re-implemented in a later release:
445 - CLEAR TRANSFORMATIONS
451 * The PROCESS IF command, which was deprecated, has been removed.
452 You may replace any usage of it by SELECT IF following
453 TEMPORARY, which has the same effect.
455 * The output format for variables created by VECTOR may now be
456 specified as part of the VECTOR syntax.
458 "Scratch files", a new PSPP extension:
460 A scratch file, like a system file, consists of a dictionary and
461 any number of cases. Small scratch files are stored in memory;
462 one that grows too large is written to disk. By default, any file
463 handle whose name begins with # is assumed to refer to a scratch
466 Scratch files can be used just about anywhere a system or portable
467 file can be used. Also, portable files are now allowed in most
468 places that system files were allowed in previous PSPP version.
470 A new CLOSE FILE HANDLE command allows the storage associated with
471 scratch files to be freed. It also allows file handles to be
472 reassigned to new files.
474 For more information on scratch files, refer to the "File Handles"
475 section in the PSPP manual. For specifics of what commands now
476 allow what kinds of files to be specified, refer to the
477 documentation on those particular commands.
481 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
482 translation, are now supported. Use FILE HANDLE to specify the
483 format of these files.
485 * Little-endian, big-endian, and VAX-endian formats are now
486 supported for integer binary formats when reading and writing
487 data files. The new RIB and WIB subcommands on the SET command
488 control endianness of integer data. The default is the host's
491 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
492 floating point binary formats when reading and writing data
493 files. The new RRB and WRB subcommands on the SET command
494 control the floating point format. The default is the host's
495 native floating point format.
497 * DATA LIST now supports the SKIP subcommand, to skip records at
498 the beginning of a file. For compatibility, DATA LIST now
499 treats N format as F format for FREE and LIST format input.
501 * The SAVE and XSAVE commands now support the UNSELECTED,
502 PERMISSIONS, NAMES, and MAP subcommands.
504 * The EXPORT command has been re-implemented to obtain better
505 results. Support for the UNSELECTED, DIGITS, and TYPE
506 subcommands has been added.
508 * For compatibility, PRINT now inserts a space at the beginning of
509 every output line, even lines that would otherwise be blank,
510 when OUTFILE is specified. (The behavior of WRITE is
513 * For compatibility, PRINT EJECT now inserts the digit `1' at the
514 beginning of each line that should begin a new page.
516 * For compatibility, WRITE now outputs the system-missing value as
517 a field filled with spaces. Binary formats are an exception.
518 (The behavior of PRINT is unchanged.)
522 * Input and output format descriptions have been rewritten. They
523 now precisely describe what is accepted on input and written on
526 * The descriptions of the PSPP system and portable file formats
527 have been extensively revised and improved.
529 For developers, the build system now requires Autoconf 2.60 and
532 Changes from 0.3.0 to 0.4.0:
534 Changes in build dependencies:
536 * The GNU Scientific Library (libgsl), version 1.6 or later, is
539 * libplot from GNU plotutils is optional. Without it, the new
540 graphing features will not work. If you do not have it
541 installed, you must run `configure' with --without-libplot.
543 * libgmp2 is no longer a dependency.
545 Newly implemented commands and statistical features:
547 * EXAMINE, including its graphing features.
549 * FREQUENCIES now supports percentiles.
557 * SORT CASES now sorts stably, that is, two cases with equal sort
558 criteria will be in the same relative order before and after the
561 * T-TEST (re-written).
563 * DATE and USE. These commands are parsed but otherwise ignored,
564 to enhance compatibility with certain command files that invoke
567 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
568 currently have no effect on PSPP output, but their values are
569 written to and read from system files and thus may affect
570 third-party software.
572 * SET EPOCH implemented.
574 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
577 * FILE HANDLE now supports custom tab widths.
579 Long variable names (and other identifiers) are now supported. Up
580 to the first 64 bytes of each identifier is significant. PSPP now
581 reads and writes system files compatible with SPSS version 12.
583 New --algorithm and --syntax command line options allow
584 SPSS-compatible or enhanced modes to be selected.
586 Support for transformation expressions has been rewritten and
587 significantly improved. Refer to the manual for details.
589 Calculation of moments (mean, standard deviation, kurtosis,
590 skewness) has been rewritten and should now be more accurate. In
591 --algorithm=enhanced mode moments may be more accurate than SPSS in
594 Numerous bugs have been fixed, too many to mention here. Many new
595 tests have been added, leading to the discovery and fixing of many
598 The ASCII output driver can now squeeze multiple blank lines into
601 Much of the code has been rewritten and refactored. It is now much
604 The FILE TYPE and REPEATING DATA commands have been disabled for
605 this release because their implementations were deemed too buggy to
606 be useful. They will be fixed and replaced in a future release.
608 New pspp-mode for Emacs (in pspp-mode.el).
610 Added rudimentary command-line completion for interactive input.
612 lib/julcal and lib/dcdflib are no longer used, so they have been
615 For developers, the build system now requires Autoconf 2.58 and
616 Automake 1.7. The included gettext has been updated to version
619 Some reports state that Texinfo 4.8, the latest version, may be
620 necessary to successfully format the documentation on some systems.
622 Version 0.3.0 changes since 0.2.3:
626 * Using alphanumeric variables in functions under AGGREGATE
629 * Under certain circumstances, the final case would be omitted
630 from the results of an AGGREGATE operation. Fixed.
632 * Undefined behavior was invoked by referencing a freed pointer
633 under certain circumstances. Fixed.
635 * A wrong record size was displayed when paging the active file to
638 * Not having enough temporary space for sorting caused a core
641 * Syntax errors in function descriptions on AGGREGATE caused core
644 * A null pointer was dereferenced, causing a core dump, when
645 PERCENTILES was specified on FREQUENCIES. This fixes the
646 problem, but PSPP still doesn't calculate percentiles.
648 * SORT always sorted in ascending order. Fixed.
650 * Some minor memory leaks in the expression parser were removed.
652 * Many assertions fixed for strict ANSI C compliance.
656 * SET ECHO ON now implemented, but turned off by default.
658 * PRINT specifier supported on END REPEAT.
662 * System libgmp2 library is used if installed instead of
663 unconditionally using the included libgmp2 subset.
665 * Extensive code cleanup, which continues.
667 * Added CORRELATIONS command parser, but not implemented.
669 Version 0.2.3 changes since 0.2.2:
673 * SPLIT FILE with a string variable caused a core dump. Fixed.
675 * Nested INCLUDEs didn't work. Fixed.
677 * The MATCH FILES procedure set the values of variables not present
678 to 0. It should have been SYSMIS. This is now fixed.
680 * The REMARK command was too aggressive about skipping lines. It
681 didn't like being the last command in a file.
683 * Comment parsing wasn't consistent with the rest of the code in its
684 idea of where one command ends and another starts. This meant
685 that sometimes commands would be mysteriously ignored. Thanks to
686 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
688 * The TABLE subcommand on MATCH FILES worked only erratically at
689 best. This fixes it. Thanks to Dr. Dirk Melcher
690 <BZN-mdksh@t-online.de> for reporting this bug.
692 * VARIABLE LABELS rejected a slash before the first variable
693 specification, contradicting the documentation. Thanks to Walter
694 M. Gray <graywm@northernc.on.ca> for reporting this bug.
696 * Because of an incorrect optimization in memory allocation,
697 CROSSTABS sometimes segfaulted when asked to output multiple
698 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
701 * CROSSTABS didn't display value labels for column and row
702 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
705 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
706 <BZN-mdksh@t-online.de> for reporting this bug.
708 * The TABLE subcommand on MATCH FILES worked only erratically at
709 best. This fixes it. Thanks to Dr. Dirk Melcher
710 <BZN-mdksh@t-online.de> for reporting this bug.
712 * VARIABLE LABELS rejected a slash before the first variable
713 specification, contradicting the documentation. Thanks to Walter
714 M. Gray <graywm@northernc.on.ca> for reporting this bug.
716 * Because of an incorrect optimization in memory allocation,
717 CROSSTABS sometimes segfaulted when asked to output multiple
718 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
721 * CROSSTABS didn't display value labels for column and row
722 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
725 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
726 <BZN-mdksh@t-online.de> for reporting this bug.
728 * MATCH FILES corrupted memory and dumped core on some syntax
731 * MATCH FILES should set numeric values not available to the
732 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
733 <BZN-mdksh@t-online.de> for reporting this bug.
735 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
736 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
740 * Some systems didn't like the way open_file was coded. Thanks to
741 Hankin <hankin@rogue.consultco.com> for pointing this out.
743 * The SAVE procedure didn't save long string variables properly.
744 Fixed by this patch. Thanks to Hankin
745 <hankin@rogue.consultco.com> for this patch.
747 * Minor documentation fixes for MATCH FILES.
749 Version 0.2.2 changes since 0.2.1:
753 * Fix behavior of PRINT SPACE for negative arguments.
755 * Fix reading some unusual system files.
757 * Fix LIST problems with very long variables. Thanks to Hankin
758 <hankin@dunno.com> for this bug report.
760 * Fix problems with some string format specifiers.
762 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
763 <BZN-mdksh@t-online.de> for reporting this bug.
765 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
766 Hankin <hankin@dunno.com> again on this one.
768 * Sometimes you may encounter a PSPP script that has to be
769 interpreted in interactive mode. Now you can use the -i flag to
772 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
