5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
7 Changes from 0.7.3 to 0.7.7:
9 * The QUICK CLUSTER command is now implemented.
11 * The "pspp" program has a new option --batch (or -b) that selects
12 "batch" syntax mode. In previous versions of PSPP this syntax mode
13 was the default. Now a new "auto" syntax mode is the default. In
14 "auto" mode, PSPP interprets most syntax files correctly regardless
15 of their intended syntax mode.
17 See the "Syntax Variants" section in the PSPP manual for more
20 * The "pspp" program has a new option --syntax-encoding that
21 specifies the encoding for syntax files listed on the command line,
22 as well as the default encoding for syntax files included with
23 INCLUDE or INSERT. The default is to accept the system locale
24 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
25 one the system file uses.
27 See the documentation for the INSERT command in the PSPP manual for
30 * The INCLUDE and INSERT commands now support the ENCODING subcommand
31 to specify the encoding for the included syntax file.
33 * The plain text output driver now properly supports multibyte UTF-8
34 characters, including double-width characters and combining
37 * Strings may now include arbitrary Unicode code points specified in
38 hexadecimal, using the syntax U'hhhh'. For example, Unicode code
39 point U+1D11E, the musical G clef character, may be expressed as
42 See the "Tokens" section in the PSPP manual for more information.
44 * In previous versions of PSPP, in a string expressed in hexadecimal
45 with X'hh' syntax, the hexadecimal digits expressed bytes in the
46 locale encoding. In this version of PSPP, X'hh' syntax always
47 expresses bytes in UTF-8 encoding.
49 See the "Tokens" section in the PSPP manual for more information.
51 * The DO REPEAT command has been reimplemented. The most prominent
52 change is that when a DO REPEAT block contains an INCLUDE or INSERT
53 command, substitutions are not applied to the included file.
55 See the "DO REPEAT" section in the PSPP manual for more information.
57 * NPAR TESTS now supports the /KRUSKAL-WALLIS and /RUNS subcommands.
59 * AUTORECODE now supports the /GROUP subcommand.
61 * The MRSETS command is now implemented.
63 * SAVE TRANSLATE is now implemented, with initial support for saving
64 data in comma-separated value and tab-delimited formats.
66 * The PRESERVE and RESTORE commands are now implemented.
68 * The HOST command has been updated to use more modern syntax.
70 * The SET and SHOW commands no longer support the ENDCMD, NULLINE,
71 PROMPT, CPROMPT, and DPROMPT subcommands. The defaults are now the
72 only supported values.
74 Changes from 0.7.2 to 0.7.3:
76 * Charts are now produced with Cairo and Pango, instead of libplot.
77 Without them, the new graphing features will not work. If you do
78 not have Cairo and Pango installed, you must run `configure' with
81 * The new "cairo" output driver supports output in PostScript, PDF,
82 and SVG formats. Its functionality is a superset of that of the
83 "postscript" driver, which has been removed. You must have Cairo
84 and Pango installed to build the "cairo" driver.
86 Changes from 0.7.1 to 0.7.2:
88 * Updated Perl module interface.
90 * Value labels for long string variables are now supported.
92 * Missing values for long string variables are now supported.
94 Changes from 0.7.0 to 0.7.1:
96 * Added a perl module to facilitate reading and writing of pspp system
97 files from perl programs.
99 Changes from 0.6.2-pre6 to 0.7.0:
101 * Custom variable and data file attributes are now supported.
102 Commands VARIABLE ATTRIBUTE and DATAFILE ATTRIBUTE have been added
103 for setting and clear attributes. Support for attributes has also
104 been added to commands that read and write system files, such as
105 SAVE and GET, as well as to the DISPLAY command.
107 * Numererous improvements to the Graphical User Interface have
108 made. Notable improvements include:
110 - Non-Ascii characters in strings, labels and variable names are
113 - A "Split Window" function is available, which makes it easier to
114 see different parts of a large data file.
116 - Data files can now be opened by specifing their name as the first
117 argument. This means that on a properly configured desktop, double
118 clicking on an icon will open the file.
121 * New statistical procedures:
126 NPAR TESTS now supports the WILCOXON and SIGN subcommands.
128 The CROSSTABS command has been completely re-implemented to fix numerous bugs.
130 * Three new commands to combine data files have been added: MATCH FILES,
131 UPDATE and ADD FILES.
133 * A tutorial chapter has been added to the user manual.
135 Changes from 0.6.1 to 0.6.2
139 - Dutch, thanks to Harry Thijssen.
141 - Brazilian Portuguese, thanks to Michel Boaventura.
143 Thanks for translations are also due to the coordinators at
144 translationproject.org.
146 * Statistical bug fixes:
148 - REGRESSION: Report correct standard error of the estimate (bug
151 - T-TEST: Report correct significance of paired sample T-test in
152 the common case (bug #26936) and corner cases. Thanks to Mike
153 Griffiths and Matej Cepl for reporting these bugs.
155 * Build fixes and changes:
157 - Fix build with GTK+ 2.17.4 and later.
159 - Make running "make" after running "configure" with different
160 settings reliably rebuild version.c.
162 - Cygwin and MinGW build fixes.
164 - Fixes for building with recent gnulib.
166 - The Makefile now honors two new variables, PSPP_LDFLAGS and
167 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
168 binaries, respectively. This makes building easier for some
171 - Fixes for "configure --enable-relocatable" (bug #25508).
173 * Data file bug fixes and changes:
175 - Fix reading text data files that contain a mix of white space
176 and commas. Now "a ,b" is treated as two fields containing "a"
177 and "b"; previously it was treated as three, with an empty field
180 - Fix writing corrupted .sav files on Windows.
182 - Fix writing variable labels longer than 252 bytes to save files.
183 Thanks to Robert Westlund for reporting this bug.
185 - Fix writing corrupted .por files (bug #26034).
187 - Fix reading .por files whose initial lines are not padded out
188 with spaces as expected.
190 - PSPP will no longer issue warnings about some .sav file records
191 or values that it does not understand. These warnings were
192 harmless, but needlessly alarmed some users.
194 - Fix crash reading empty string fields from PostgreSQL databases.
196 * Bug fixes that affect PSPP and PSPPIRE:
198 - Users may now control precision of output statistics. Instead
199 of hard coding the width and decimals of output numbers, respect
200 the default format in most instances. Counts are now normally
201 displayed with the format of the weight variable, if any.
203 - Fix crash when an INSERT command specifies the name of a file
204 that does not exist (bug #24569).
206 - Fix crash when CROSSTABS specifies a long-string variable (bugs
209 - Fix crash drawing pie charts with many segments.
211 - Fix crash when NUMERIC specifies an invalid format.
213 * PSPPIRE bug fixes and changes:
215 - On Windows, write the output file to the user's home directory
216 instead of the current directory, to better match user
219 - Some data editor fixes.
223 - Fix typo in BINOMIAL section of user manual (bug #25892).
225 Changes from 0.6.0 to 0.6.1:
227 * Statistical bug fixes:
229 - Report correct standardized regression coefficients in linear
230 regression output (bug #23567).
232 * Bug fixes that affect PSPP and PSPPIRE:
234 - Avoid crash with pie charts (bug #24014).
236 - Don't append % to count totals (bug #24003).
238 - Don't crash on bad input (bug #24031).
240 - Don't crash if "end data." is not left aligned (bug #24115).
242 - Change default workspace value to 64 MB, to avoid unnecessary
243 disk accesses on modern machines.
247 - Add ".sav" or ".por" suffix to filename when saving with Save_As
250 - Make it possible to reopen the output window on Windows (bug
253 - A POSIX regular expression library is now included and used
254 automatically if the host does not have one or has one that is
257 * Build fixes and changes:
259 - Work around bug in GSL that prevented build with recent GCC
260 versions without manually adding -fgnu89-inline to CFLAGS.
262 - Also warn about missing prerequisites as we encounter them (bug
265 - Distribute necessary files to allow users working from the
266 distributed tarball to configure with --enable-gui-tools.
268 - Append $(EXEEXT_FOR_BUILD) to output file name when building
269 q2c, fixing build problems on Windows.
271 - GSL 1.8 or later is now required.
273 - Build errors with --enable-relocatable were fixed.
275 * The German translations were removed, since native German speakers
276 found them too poor to be useful.
278 Changes from 0.4.0 to 0.6.0:
280 * The PSPP license is now version 3 or later of the GNU General
281 Public License. Previously, it was version 2 or later.
283 * PSPP now has a graphical interface, called PSPPIRE. This
284 interface allows you to enter data and variable definitions
285 interactively. Commands may be executed in syntax form, or by
286 using the interactive dialog boxes available from the dropdown
289 * A few sample syntax files are now included in the `examples'
292 * Numerous major and minor bugs have been fixed.
296 * The INSTALL file now reflects the details of how to install
297 PSPP. It is a tailored version of the generic installation
298 instructions, instead of a verbatim copy.
300 * iconv, which is ordinarily installed as part of a Unix-like
301 system, is now required. If you don't have it already, you can
302 install GNU libiconv (http://www.gnu.org/software/libiconv/).
304 * libxml2 and zlib are new optional dependencies. They are
305 required to use PSPP's support for reading Gnumeric files.
307 Statistical procedure changes:
309 * REGRESSION is a new procedure for fitting linear models to data
310 via least-squares estimation.
312 * NPAR TESTS is a new procedure for non-parametric tests. In this
313 release, it supports binomial and chi-square tests.
315 * RANK is a new procedure to rank variables. It supports numerous
318 * FREQUENCIES can now output histograms and pie charts. These
319 features were present in earlier releases, but not documented.
321 User interface changes:
323 * In many situations where PSPP once terminated with a fatal
324 error, PSPP now recovers and continues execution.
326 * PSPP is now able to start up and run even if it cannot find its
329 * Journaling of interactive commands to a disk file is now
330 implemented. By default, journaling is enabled, to a file named
331 `pspp.jnl' in the current directory. SET JOURNAL may be used to
334 * The use of `+' between syntax file names on the command line to
335 prevent the dictionary from being cleared between their
336 executions is no longer supported. All syntax files are now
337 executed as if `+' had been specified.
339 * The -d/--define and -u/--undef command line options are no
340 longer supported. Instead, use /usr/bin/env or shell primitives
341 to define or clear environment variables before invoking PSPP.
343 * If a syntax file named named `rc' is found in a configuration
344 directory (such as $HOME/.pspp), it is executed before any
345 syntax file specified on the command line. The -r or
346 --no-statrc command line option may be used to disable this
351 * Output configuration options have changed. Please refer to the
352 manual for a full description of the available options.
354 In consequence, you will need to reinstall your "devices" file.
355 "make install" will do this for you.
357 * Most error messages are now written to PSPP output files by
358 default. SET ERROR can be used to disable this behavior.
360 * When invoked interactively, PSPP now by default produces output
361 on the terminal, piping it through the "more" program.
362 Previously, by default output was written only to file
363 pspp.list. On most terminals, the page length used for output
364 automatically adapts to the terminal size, even if the terminal
369 - This driver now supports charts in output. Charts are written
370 as separate files that the main output file refers to. By
371 default, charts are written in PNG format to files named
372 pspp-1.png, pspp-2.png, and so on.
374 - Configurations are provided that use VT100 (and xterm)
375 line-drawing characters in tables. The option "-o list-vt100"
376 requests use of this device for output to pspp.list.
380 - The default paper size is now determined using the PAPERSIZE
381 environment variable, or the LC_PAPER locale category on
382 systems that support it. If these are not set, the default is
383 now A4, instead of US letter. To make US letter the default,
384 set PAPERSIZE to "letter" in your environment.
386 - Font metrics are now read from AFM files, instead of
387 Groff-format metrics files. PostScript fonts can now be
390 In consequence, you will need to install an AFM file for each
391 font used in PostScript output. "make install" will install
392 AFM files for the standard PostScript fonts, including the
393 ones that the PostScript driver uses by default.
395 - Standard paper sizes no longer need to be specified through a
396 configuration file. The "papersize" configuration file is no
397 longer needed, or supported.
399 - The PostScript prologue is no longer obtained from the
400 "ps-prologue" configuration file. This configuration file is
401 no longer needed, or supported.
405 - The HTML prologue is no longer obtained from the
406 "html-prologue" configuration file. This configuration file
407 is no longer needed, or supported.
409 Command language changes:
411 * The following commands are new:
413 - GET DATA, which currently supports reading Gnumeric files and
414 text data files. It will be extended later to read other
415 types of foreign data.
417 - CD, to change the current directory.
419 - INSERT, to execute a syntax file.
421 - DELETE VARIABLES, to remove variables from the active file
424 - ADD DOCUMENT, to add text to active file documents.
426 - CLOSE FILE HANDLE (a PSPP extension; see below).
428 - XEXPORT, a PSPP extension that is a transformation equivalent
431 * The following functions for transformation expressions are new:
433 - DATEDIFF, for computing the difference of two dates.
435 - DATESUM, for advancing a date by a specified duration.
437 - VALUELABEL, to obtain the value label for a value.
439 * PSPP now supports very long string variables (over 255 bytes
442 * MATCH FILES now supports the FIRST and LAST subcommands.
444 * Previous versions of PSPP prohibited using commands to both read and
445 write a single file at the same time. Now, PSPP allows this, and
446 the new version of the file atomically replaces the old version.
448 * The following commands are no longer available. They will be
449 re-implemented in a later release:
451 - CLEAR TRANSFORMATIONS
457 * The PROCESS IF command, which was deprecated, has been removed.
458 You may replace any usage of it by SELECT IF following
459 TEMPORARY, which has the same effect.
461 * The output format for variables created by VECTOR may now be
462 specified as part of the VECTOR syntax.
464 "Scratch files", a new PSPP extension:
466 A scratch file, like a system file, consists of a dictionary and
467 any number of cases. Small scratch files are stored in memory;
468 one that grows too large is written to disk. By default, any file
469 handle whose name begins with # is assumed to refer to a scratch
472 Scratch files can be used just about anywhere a system or portable
473 file can be used. Also, portable files are now allowed in most
474 places that system files were allowed in previous PSPP version.
476 A new CLOSE FILE HANDLE command allows the storage associated with
477 scratch files to be freed. It also allows file handles to be
478 reassigned to new files.
480 For more information on scratch files, refer to the "File Handles"
481 section in the PSPP manual. For specifics of what commands now
482 allow what kinds of files to be specified, refer to the
483 documentation on those particular commands.
487 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
488 translation, are now supported. Use FILE HANDLE to specify the
489 format of these files.
491 * Little-endian, big-endian, and VAX-endian formats are now
492 supported for integer binary formats when reading and writing
493 data files. The new RIB and WIB subcommands on the SET command
494 control endianness of integer data. The default is the host's
497 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
498 floating point binary formats when reading and writing data
499 files. The new RRB and WRB subcommands on the SET command
500 control the floating point format. The default is the host's
501 native floating point format.
503 * DATA LIST now supports the SKIP subcommand, to skip records at
504 the beginning of a file. For compatibility, DATA LIST now
505 treats N format as F format for FREE and LIST format input.
507 * The SAVE and XSAVE commands now support the UNSELECTED,
508 PERMISSIONS, NAMES, and MAP subcommands.
510 * The EXPORT command has been re-implemented to obtain better
511 results. Support for the UNSELECTED, DIGITS, and TYPE
512 subcommands has been added.
514 * For compatibility, PRINT now inserts a space at the beginning of
515 every output line, even lines that would otherwise be blank,
516 when OUTFILE is specified. (The behavior of WRITE is
519 * For compatibility, PRINT EJECT now inserts the digit `1' at the
520 beginning of each line that should begin a new page.
522 * For compatibility, WRITE now outputs the system-missing value as
523 a field filled with spaces. Binary formats are an exception.
524 (The behavior of PRINT is unchanged.)
528 * Input and output format descriptions have been rewritten. They
529 now precisely describe what is accepted on input and written on
532 * The descriptions of the PSPP system and portable file formats
533 have been extensively revised and improved.
535 For developers, the build system now requires Autoconf 2.60 and
538 Changes from 0.3.0 to 0.4.0:
540 Changes in build dependencies:
542 * The GNU Scientific Library (libgsl), version 1.6 or later, is
545 * libplot from GNU plotutils is optional. Without it, the new
546 graphing features will not work. If you do not have it
547 installed, you must run `configure' with --without-libplot.
549 * libgmp2 is no longer a dependency.
551 Newly implemented commands and statistical features:
553 * EXAMINE, including its graphing features.
555 * FREQUENCIES now supports percentiles.
563 * SORT CASES now sorts stably, that is, two cases with equal sort
564 criteria will be in the same relative order before and after the
567 * T-TEST (re-written).
569 * DATE and USE. These commands are parsed but otherwise ignored,
570 to enhance compatibility with certain command files that invoke
573 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
574 currently have no effect on PSPP output, but their values are
575 written to and read from system files and thus may affect
576 third-party software.
578 * SET EPOCH implemented.
580 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
583 * FILE HANDLE now supports custom tab widths.
585 Long variable names (and other identifiers) are now supported. Up
586 to the first 64 bytes of each identifier is significant. PSPP now
587 reads and writes system files compatible with SPSS version 12.
589 New --algorithm and --syntax command line options allow
590 SPSS-compatible or enhanced modes to be selected.
592 Support for transformation expressions has been rewritten and
593 significantly improved. Refer to the manual for details.
595 Calculation of moments (mean, standard deviation, kurtosis,
596 skewness) has been rewritten and should now be more accurate. In
597 --algorithm=enhanced mode moments may be more accurate than SPSS in
600 Numerous bugs have been fixed, too many to mention here. Many new
601 tests have been added, leading to the discovery and fixing of many
604 The ASCII output driver can now squeeze multiple blank lines into
607 Much of the code has been rewritten and refactored. It is now much
610 The FILE TYPE and REPEATING DATA commands have been disabled for
611 this release because their implementations were deemed too buggy to
612 be useful. They will be fixed and replaced in a future release.
614 New pspp-mode for Emacs (in pspp-mode.el).
616 Added rudimentary command-line completion for interactive input.
618 lib/julcal and lib/dcdflib are no longer used, so they have been
621 For developers, the build system now requires Autoconf 2.58 and
622 Automake 1.7. The included gettext has been updated to version
625 Some reports state that Texinfo 4.8, the latest version, may be
626 necessary to successfully format the documentation on some systems.
628 Version 0.3.0 changes since 0.2.3:
632 * Using alphanumeric variables in functions under AGGREGATE
635 * Under certain circumstances, the final case would be omitted
636 from the results of an AGGREGATE operation. Fixed.
638 * Undefined behavior was invoked by referencing a freed pointer
639 under certain circumstances. Fixed.
641 * A wrong record size was displayed when paging the active file to
644 * Not having enough temporary space for sorting caused a core
647 * Syntax errors in function descriptions on AGGREGATE caused core
650 * A null pointer was dereferenced, causing a core dump, when
651 PERCENTILES was specified on FREQUENCIES. This fixes the
652 problem, but PSPP still doesn't calculate percentiles.
654 * SORT always sorted in ascending order. Fixed.
656 * Some minor memory leaks in the expression parser were removed.
658 * Many assertions fixed for strict ANSI C compliance.
662 * SET ECHO ON now implemented, but turned off by default.
664 * PRINT specifier supported on END REPEAT.
668 * System libgmp2 library is used if installed instead of
669 unconditionally using the included libgmp2 subset.
671 * Extensive code cleanup, which continues.
673 * Added CORRELATIONS command parser, but not implemented.
675 Version 0.2.3 changes since 0.2.2:
679 * SPLIT FILE with a string variable caused a core dump. Fixed.
681 * Nested INCLUDEs didn't work. Fixed.
683 * The MATCH FILES procedure set the values of variables not present
684 to 0. It should have been SYSMIS. This is now fixed.
686 * The REMARK command was too aggressive about skipping lines. It
687 didn't like being the last command in a file.
689 * Comment parsing wasn't consistent with the rest of the code in its
690 idea of where one command ends and another starts. This meant
691 that sometimes commands would be mysteriously ignored. Thanks to
692 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
694 * The TABLE subcommand on MATCH FILES worked only erratically at
695 best. This fixes it. Thanks to Dr. Dirk Melcher
696 <BZN-mdksh@t-online.de> for reporting this bug.
698 * VARIABLE LABELS rejected a slash before the first variable
699 specification, contradicting the documentation. Thanks to Walter
700 M. Gray <graywm@northernc.on.ca> for reporting this bug.
702 * Because of an incorrect optimization in memory allocation,
703 CROSSTABS sometimes segfaulted when asked to output multiple
704 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
707 * CROSSTABS didn't display value labels for column and row
708 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
711 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
712 <BZN-mdksh@t-online.de> for reporting this bug.
714 * The TABLE subcommand on MATCH FILES worked only erratically at
715 best. This fixes it. Thanks to Dr. Dirk Melcher
716 <BZN-mdksh@t-online.de> for reporting this bug.
718 * VARIABLE LABELS rejected a slash before the first variable
719 specification, contradicting the documentation. Thanks to Walter
720 M. Gray <graywm@northernc.on.ca> for reporting this bug.
722 * Because of an incorrect optimization in memory allocation,
723 CROSSTABS sometimes segfaulted when asked to output multiple
724 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
727 * CROSSTABS didn't display value labels for column and row
728 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
731 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
732 <BZN-mdksh@t-online.de> for reporting this bug.
734 * MATCH FILES corrupted memory and dumped core on some syntax
737 * MATCH FILES should set numeric values not available to the
738 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
739 <BZN-mdksh@t-online.de> for reporting this bug.
741 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
742 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
746 * Some systems didn't like the way open_file was coded. Thanks to
747 Hankin <hankin@rogue.consultco.com> for pointing this out.
749 * The SAVE procedure didn't save long string variables properly.
750 Fixed by this patch. Thanks to Hankin
751 <hankin@rogue.consultco.com> for this patch.
753 * Minor documentation fixes for MATCH FILES.
755 Version 0.2.2 changes since 0.2.1:
759 * Fix behavior of PRINT SPACE for negative arguments.
761 * Fix reading some unusual system files.
763 * Fix LIST problems with very long variables. Thanks to Hankin
764 <hankin@dunno.com> for this bug report.
766 * Fix problems with some string format specifiers.
768 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
769 <BZN-mdksh@t-online.de> for reporting this bug.
771 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
772 Hankin <hankin@dunno.com> again on this one.
774 * Sometimes you may encounter a PSPP script that has to be
