5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
13 * PSPPIRE graphical user interface improvements:
15 - A new set of icons has been contributed.
17 - Syntax windows now parse syntax in "auto" mode, which in practice
18 should mean that both "batch" and "interactive" syntax now works,
19 instead of just "interactive" syntax.
21 - The variable pane of data windows now include a Role column.
25 - System files written by IBM SPSS 21 are now read without warnings.
27 - System files written by "VOXCO INTERVIEWER 4.3" are now read
30 - PSPPIRE should now more gracefully handle syntax files that contain
33 Changes from 0.6.2 to 0.8.0:
50 - PRESERVE and RESTORE
54 - SAVE TRANSLATE to CSV and tab-delimited files
58 * Changes to existing commands:
60 - AUTORECODE has a new GROUP subcommand.
62 - CROSSTABS has been re-implemented to fix numerous bugs.
64 - EXAMINE: /MISSING=LISTWISE is now the default.
66 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
67 contains an INCLUDE or INSERT command, substitutions are not
68 applied to the included file.
70 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
72 - HOST has been updated to use more modern syntax.
74 - Most commands that work with data files now support a new
77 - MISSING VALUES can now assign missing values to long string
80 - ONEWAY: the POSTHOC subcommand is now implemented.
82 - The following new subcommands to NPAR TESTS have been implemented:
83 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
84 MCNEMAR, SIGN, WILCOXON, and RUNS
86 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
87 DPROMPT subcommands. The defaults are now fixed values.
89 - SHOW now has a JOURNAL subcommand, to show the location of the
92 - VALUE LABELS can now assign value labels to long string
95 * Other language changes:
97 - The new DATASET commands replace the "scratch file" PSPP
98 extension, which is no longer supported.
100 - Strings may now include arbitrary Unicode code points specified
101 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
102 code point U+1D11E, the musical G clef character, may be
103 expressed as U'1D11E'.
105 See the "Tokens" section in the PSPP manual for more information.
107 - In previous versions of PSPP, in a string expressed in
108 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
109 bytes in the locale encoding. In this version of PSPP, X'hh'
110 syntax always expresses bytes in UTF-8 encoding.
112 See the "Tokens" section in the PSPP manual for more information.
114 * PSPPIRE graphical user interface improvements:
116 - Added support for non-ASCII characters in strings, labels and
119 - A "Split Window" function is available, which makes it easier to
120 see different parts of a large data file.
122 - Data files can now be opened by specifing their name as the first
123 argument. This means that on a properly configured desktop, double
124 clicking on an icon will open the file.
126 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
127 via using an "intelligent" application assistant dialog.
131 - The new "cairo" output driver supports output in PostScript, PDF,
132 and SVG formats. Its functionality is a superset of that of the
133 "postscript" driver, which has been removed. You must have Cairo
134 and Pango installed to build the "cairo" driver.
136 - Charts are now produced with Cairo and Pango, instead of libplot.
137 Without them, the new graphing features will not work. If you do
138 not have Cairo and Pango installed, you must run `configure' with
141 - The plain text output driver now properly supports multibyte UTF-8
142 characters, including double-width characters and combining
145 - Output to OpenDocument format is now supported.
147 - The HTML output is much improved.
149 * The "pspp" program has a new option --batch (or -b) that selects
150 "batch" syntax mode. In previous versions of PSPP this syntax mode
151 was the default. Now a new "auto" syntax mode is the default. In
152 "auto" mode, PSPP interprets most syntax files correctly regardless
153 of their intended syntax mode.
155 See the "Syntax Variants" section in the PSPP manual for more
158 * The "pspp" program has a new option --syntax-encoding that
159 specifies the encoding for syntax files listed on the command line,
160 as well as the default encoding for syntax files included with
161 INCLUDE or INSERT. The default is to accept the system locale
162 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
163 one the system file uses.
165 See the documentation for the INSERT command in the PSPP manual for
168 * Text data files that PRINT and WRITE creates now use the system
169 native line ends by default (CRLF on Windows, LF only elsewhere).
170 Use the new ENDS subcommand on FILE HANDLE to override the default.
172 * A new Perl module allows Perl programs to read and write PSPP
175 * A tutorial chapter has been added to the user manual.
177 Changes from 0.6.1 to 0.6.2:
181 - Dutch, thanks to Harry Thijssen.
183 - Brazilian Portuguese, thanks to Michel Boaventura.
185 Thanks for translations are also due to the coordinators at
186 translationproject.org.
188 * Statistical bug fixes:
190 - REGRESSION: Report correct standard error of the estimate (bug
193 - T-TEST: Report correct significance of paired sample T-test in
194 the common case (bug #26936) and corner cases. Thanks to Mike
195 Griffiths and Matej Cepl for reporting these bugs.
197 * Build fixes and changes:
199 - Fix build with GTK+ 2.17.4 and later.
201 - Make running "make" after running "configure" with different
202 settings reliably rebuild version.c.
204 - Cygwin and MinGW build fixes.
206 - Fixes for building with recent gnulib.
208 - The Makefile now honors two new variables, PSPP_LDFLAGS and
209 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
210 binaries, respectively. This makes building easier for some
213 - Fixes for "configure --enable-relocatable" (bug #25508).
215 * Data file bug fixes and changes:
217 - Fix reading text data files that contain a mix of white space
218 and commas. Now "a ,b" is treated as two fields containing "a"
219 and "b"; previously it was treated as three, with an empty field
222 - Fix writing corrupted .sav files on Windows.
224 - Fix writing variable labels longer than 252 bytes to save files.
225 Thanks to Robert Westlund for reporting this bug.
227 - Fix writing corrupted .por files (bug #26034).
229 - Fix reading .por files whose initial lines are not padded out
230 with spaces as expected.
232 - PSPP will no longer issue warnings about some .sav file records
233 or values that it does not understand. These warnings were
234 harmless, but needlessly alarmed some users.
236 - Fix crash reading empty string fields from PostgreSQL databases.
238 * Bug fixes that affect PSPP and PSPPIRE:
240 - Users may now control precision of output statistics. Instead
241 of hard coding the width and decimals of output numbers, respect
242 the default format in most instances. Counts are now normally
243 displayed with the format of the weight variable, if any.
245 - Fix crash when an INSERT command specifies the name of a file
246 that does not exist (bug #24569).
248 - Fix crash when CROSSTABS specifies a long-string variable (bugs
251 - Fix crash drawing pie charts with many segments.
253 - Fix crash when NUMERIC specifies an invalid format.
255 * PSPPIRE bug fixes and changes:
257 - On Windows, write the output file to the user's home directory
258 instead of the current directory, to better match user
261 - Some data editor fixes.
265 - Fix typo in BINOMIAL section of user manual (bug #25892).
267 Changes from 0.6.0 to 0.6.1:
269 * Statistical bug fixes:
271 - Report correct standardized regression coefficients in linear
272 regression output (bug #23567).
274 * Bug fixes that affect PSPP and PSPPIRE:
276 - Avoid crash with pie charts (bug #24014).
278 - Don't append % to count totals (bug #24003).
280 - Don't crash on bad input (bug #24031).
282 - Don't crash if "end data." is not left aligned (bug #24115).
284 - Change default workspace value to 64 MB, to avoid unnecessary
285 disk accesses on modern machines.
289 - Add ".sav" or ".por" suffix to filename when saving with Save_As
292 - Make it possible to reopen the output window on Windows (bug
295 - A POSIX regular expression library is now included and used
296 automatically if the host does not have one or has one that is
299 * Build fixes and changes:
301 - Work around bug in GSL that prevented build with recent GCC
302 versions without manually adding -fgnu89-inline to CFLAGS.
304 - Also warn about missing prerequisites as we encounter them (bug
307 - Distribute necessary files to allow users working from the
308 distributed tarball to configure with --enable-gui-tools.
310 - Append $(EXEEXT_FOR_BUILD) to output file name when building
311 q2c, fixing build problems on Windows.
313 - GSL 1.8 or later is now required.
315 - Build errors with --enable-relocatable were fixed.
317 * The German translations were removed, since native German speakers
318 found them too poor to be useful.
320 Changes from 0.4.0 to 0.6.0:
322 * The PSPP license is now version 3 or later of the GNU General
323 Public License. Previously, it was version 2 or later.
325 * PSPP now has a graphical interface, called PSPPIRE. This
326 interface allows you to enter data and variable definitions
327 interactively. Commands may be executed in syntax form, or by
328 using the interactive dialog boxes available from the dropdown
331 * A few sample syntax files are now included in the `examples'
334 * Numerous major and minor bugs have been fixed.
338 * The INSTALL file now reflects the details of how to install
339 PSPP. It is a tailored version of the generic installation
340 instructions, instead of a verbatim copy.
342 * iconv, which is ordinarily installed as part of a Unix-like
343 system, is now required. If you don't have it already, you can
344 install GNU libiconv (http://www.gnu.org/software/libiconv/).
346 * libxml2 and zlib are new optional dependencies. They are
347 required to use PSPP's support for reading Gnumeric files.
349 Statistical procedure changes:
351 * REGRESSION is a new procedure for fitting linear models to data
352 via least-squares estimation.
354 * NPAR TESTS is a new procedure for non-parametric tests. In this
355 release, it supports binomial and chi-square tests.
357 * RANK is a new procedure to rank variables. It supports numerous
360 * FREQUENCIES can now output histograms and pie charts. These
361 features were present in earlier releases, but not documented.
363 User interface changes:
365 * In many situations where PSPP once terminated with a fatal
366 error, PSPP now recovers and continues execution.
368 * PSPP is now able to start up and run even if it cannot find its
371 * Journaling of interactive commands to a disk file is now
372 implemented. By default, journaling is enabled, to a file named
373 `pspp.jnl' in the current directory. SET JOURNAL may be used to
376 * The use of `+' between syntax file names on the command line to
377 prevent the dictionary from being cleared between their
378 executions is no longer supported. All syntax files are now
379 executed as if `+' had been specified.
381 * The -d/--define and -u/--undef command line options are no
382 longer supported. Instead, use /usr/bin/env or shell primitives
383 to define or clear environment variables before invoking PSPP.
385 * If a syntax file named named `rc' is found in a configuration
386 directory (such as $HOME/.pspp), it is executed before any
387 syntax file specified on the command line. The -r or
388 --no-statrc command line option may be used to disable this
393 * Output configuration options have changed. Please refer to the
394 manual for a full description of the available options.
396 In consequence, you will need to reinstall your "devices" file.
397 "make install" will do this for you.
399 * Most error messages are now written to PSPP output files by
400 default. SET ERROR can be used to disable this behavior.
402 * When invoked interactively, PSPP now by default produces output
403 on the terminal, piping it through the "more" program.
404 Previously, by default output was written only to file
405 pspp.list. On most terminals, the page length used for output
406 automatically adapts to the terminal size, even if the terminal
411 - This driver now supports charts in output. Charts are written
412 as separate files that the main output file refers to. By
413 default, charts are written in PNG format to files named
414 pspp-1.png, pspp-2.png, and so on.
416 - Configurations are provided that use VT100 (and xterm)
417 line-drawing characters in tables. The option "-o list-vt100"
418 requests use of this device for output to pspp.list.
422 - The default paper size is now determined using the PAPERSIZE
423 environment variable, or the LC_PAPER locale category on
424 systems that support it. If these are not set, the default is
425 now A4, instead of US letter. To make US letter the default,
426 set PAPERSIZE to "letter" in your environment.
428 - Font metrics are now read from AFM files, instead of
429 Groff-format metrics files. PostScript fonts can now be
432 In consequence, you will need to install an AFM file for each
433 font used in PostScript output. "make install" will install
434 AFM files for the standard PostScript fonts, including the
435 ones that the PostScript driver uses by default.
437 - Standard paper sizes no longer need to be specified through a
438 configuration file. The "papersize" configuration file is no
439 longer needed, or supported.
441 - The PostScript prologue is no longer obtained from the
442 "ps-prologue" configuration file. This configuration file is
443 no longer needed, or supported.
447 - The HTML prologue is no longer obtained from the
448 "html-prologue" configuration file. This configuration file
449 is no longer needed, or supported.
451 Command language changes:
453 * The following commands are new:
455 - GET DATA, which currently supports reading Gnumeric files and
456 text data files. It will be extended later to read other
457 types of foreign data.
459 - CD, to change the current directory.
461 - INSERT, to execute a syntax file.
463 - DELETE VARIABLES, to remove variables from the active file
466 - ADD DOCUMENT, to add text to active file documents.
468 - CLOSE FILE HANDLE (a PSPP extension; see below).
470 - XEXPORT, a PSPP extension that is a transformation equivalent
473 * The following functions for transformation expressions are new:
475 - DATEDIFF, for computing the difference of two dates.
477 - DATESUM, for advancing a date by a specified duration.
479 - VALUELABEL, to obtain the value label for a value.
481 * PSPP now supports very long string variables (over 255 bytes
484 * MATCH FILES now supports the FIRST and LAST subcommands.
486 * Previous versions of PSPP prohibited using commands to both read and
487 write a single file at the same time. Now, PSPP allows this, and
488 the new version of the file atomically replaces the old version.
490 * The following commands are no longer available. They will be
491 re-implemented in a later release:
493 - CLEAR TRANSFORMATIONS
499 * The PROCESS IF command, which was deprecated, has been removed.
500 You may replace any usage of it by SELECT IF following
501 TEMPORARY, which has the same effect.
503 * The output format for variables created by VECTOR may now be
504 specified as part of the VECTOR syntax.
506 "Scratch files", a new PSPP extension:
508 A scratch file, like a system file, consists of a dictionary and
509 any number of cases. Small scratch files are stored in memory;
510 one that grows too large is written to disk. By default, any file
511 handle whose name begins with # is assumed to refer to a scratch
514 Scratch files can be used just about anywhere a system or portable
515 file can be used. Also, portable files are now allowed in most
516 places that system files were allowed in previous PSPP version.
518 A new CLOSE FILE HANDLE command allows the storage associated with
519 scratch files to be freed. It also allows file handles to be
520 reassigned to new files.
522 For more information on scratch files, refer to the "File Handles"
523 section in the PSPP manual. For specifics of what commands now
524 allow what kinds of files to be specified, refer to the
525 documentation on those particular commands.
529 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
530 translation, are now supported. Use FILE HANDLE to specify the
531 format of these files.
533 * Little-endian, big-endian, and VAX-endian formats are now
534 supported for integer binary formats when reading and writing
535 data files. The new RIB and WIB subcommands on the SET command
536 control endianness of integer data. The default is the host's
539 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
540 floating point binary formats when reading and writing data
541 files. The new RRB and WRB subcommands on the SET command
542 control the floating point format. The default is the host's
543 native floating point format.
545 * DATA LIST now supports the SKIP subcommand, to skip records at
546 the beginning of a file. For compatibility, DATA LIST now
547 treats N format as F format for FREE and LIST format input.
549 * The SAVE and XSAVE commands now support the UNSELECTED,
550 PERMISSIONS, NAMES, and MAP subcommands.
552 * The EXPORT command has been re-implemented to obtain better
553 results. Support for the UNSELECTED, DIGITS, and TYPE
554 subcommands has been added.
556 * For compatibility, PRINT now inserts a space at the beginning of
557 every output line, even lines that would otherwise be blank,
558 when OUTFILE is specified. (The behavior of WRITE is
561 * For compatibility, PRINT EJECT now inserts the digit `1' at the
562 beginning of each line that should begin a new page.
564 * For compatibility, WRITE now outputs the system-missing value as
565 a field filled with spaces. Binary formats are an exception.
566 (The behavior of PRINT is unchanged.)
570 * Input and output format descriptions have been rewritten. They
571 now precisely describe what is accepted on input and written on
574 * The descriptions of the PSPP system and portable file formats
575 have been extensively revised and improved.
577 For developers, the build system now requires Autoconf 2.60 and
580 Changes from 0.3.0 to 0.4.0:
582 Changes in build dependencies:
584 * The GNU Scientific Library (libgsl), version 1.6 or later, is
587 * libplot from GNU plotutils is optional. Without it, the new
588 graphing features will not work. If you do not have it
589 installed, you must run `configure' with --without-libplot.
591 * libgmp2 is no longer a dependency.
593 Newly implemented commands and statistical features:
595 * EXAMINE, including its graphing features.
597 * FREQUENCIES now supports percentiles.
605 * SORT CASES now sorts stably, that is, two cases with equal sort
606 criteria will be in the same relative order before and after the
609 * T-TEST (re-written).
611 * DATE and USE. These commands are parsed but otherwise ignored,
612 to enhance compatibility with certain command files that invoke
615 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
616 currently have no effect on PSPP output, but their values are
617 written to and read from system files and thus may affect
618 third-party software.
620 * SET EPOCH implemented.
622 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
625 * FILE HANDLE now supports custom tab widths.
627 Long variable names (and other identifiers) are now supported. Up
628 to the first 64 bytes of each identifier is significant. PSPP now
629 reads and writes system files compatible with SPSS version 12.
631 New --algorithm and --syntax command line options allow
632 SPSS-compatible or enhanced modes to be selected.
634 Support for transformation expressions has been rewritten and
635 significantly improved. Refer to the manual for details.
637 Calculation of moments (mean, standard deviation, kurtosis,
638 skewness) has been rewritten and should now be more accurate. In
639 --algorithm=enhanced mode moments may be more accurate than SPSS in
642 Numerous bugs have been fixed, too many to mention here. Many new
643 tests have been added, leading to the discovery and fixing of many
646 The ASCII output driver can now squeeze multiple blank lines into
649 Much of the code has been rewritten and refactored. It is now much
652 The FILE TYPE and REPEATING DATA commands have been disabled for
653 this release because their implementations were deemed too buggy to
654 be useful. They will be fixed and replaced in a future release.
656 New pspp-mode for Emacs (in pspp-mode.el).
658 Added rudimentary command-line completion for interactive input.
660 lib/julcal and lib/dcdflib are no longer used, so they have been
663 For developers, the build system now requires Autoconf 2.58 and
664 Automake 1.7. The included gettext has been updated to version
667 Some reports state that Texinfo 4.8, the latest version, may be
668 necessary to successfully format the documentation on some systems.
670 Version 0.3.0 changes since 0.2.3:
674 * Using alphanumeric variables in functions under AGGREGATE
677 * Under certain circumstances, the final case would be omitted
678 from the results of an AGGREGATE operation. Fixed.
680 * Undefined behavior was invoked by referencing a freed pointer
681 under certain circumstances. Fixed.
683 * A wrong record size was displayed when paging the active file to
686 * Not having enough temporary space for sorting caused a core
689 * Syntax errors in function descriptions on AGGREGATE caused core
692 * A null pointer was dereferenced, causing a core dump, when
693 PERCENTILES was specified on FREQUENCIES. This fixes the
694 problem, but PSPP still doesn't calculate percentiles.
696 * SORT always sorted in ascending order. Fixed.
698 * Some minor memory leaks in the expression parser were removed.
700 * Many assertions fixed for strict ANSI C compliance.
704 * SET ECHO ON now implemented, but turned off by default.
706 * PRINT specifier supported on END REPEAT.
710 * System libgmp2 library is used if installed instead of
711 unconditionally using the included libgmp2 subset.
713 * Extensive code cleanup, which continues.
715 * Added CORRELATIONS command parser, but not implemented.
717 Version 0.2.3 changes since 0.2.2:
721 * SPLIT FILE with a string variable caused a core dump. Fixed.
723 * Nested INCLUDEs didn't work. Fixed.
725 * The MATCH FILES procedure set the values of variables not present
726 to 0. It should have been SYSMIS. This is now fixed.
728 * The REMARK command was too aggressive about skipping lines. It
729 didn't like being the last command in a file.
731 * Comment parsing wasn't consistent with the rest of the code in its
732 idea of where one command ends and another starts. This meant
733 that sometimes commands would be mysteriously ignored. Thanks to
734 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
736 * The TABLE subcommand on MATCH FILES worked only erratically at
737 best. This fixes it. Thanks to Dr. Dirk Melcher
738 <BZN-mdksh@t-online.de> for reporting this bug.
740 * VARIABLE LABELS rejected a slash before the first variable
741 specification, contradicting the documentation. Thanks to Walter
742 M. Gray <graywm@northernc.on.ca> for reporting this bug.
744 * Because of an incorrect optimization in memory allocation,
745 CROSSTABS sometimes segfaulted when asked to output multiple
746 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
749 * CROSSTABS didn't display value labels for column and row
750 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
753 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
754 <BZN-mdksh@t-online.de> for reporting this bug.
756 * The TABLE subcommand on MATCH FILES worked only erratically at
757 best. This fixes it. Thanks to Dr. Dirk Melcher
758 <BZN-mdksh@t-online.de> for reporting this bug.
760 * VARIABLE LABELS rejected a slash before the first variable
761 specification, contradicting the documentation. Thanks to Walter
762 M. Gray <graywm@northernc.on.ca> for reporting this bug.
764 * Because of an incorrect optimization in memory allocation,
765 CROSSTABS sometimes segfaulted when asked to output multiple
766 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
769 * CROSSTABS didn't display value labels for column and row
770 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
773 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
774 <BZN-mdksh@t-online.de> for reporting this bug.
776 * MATCH FILES corrupted memory and dumped core on some syntax
779 * MATCH FILES should set numeric values not available to the
780 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
781 <BZN-mdksh@t-online.de> for reporting this bug.
783 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
784 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
788 * Some systems didn't like the way open_file was coded. Thanks to
789 Hankin <hankin@rogue.consultco.com> for pointing this out.
791 * The SAVE procedure didn't save long string variables properly.
792 Fixed by this patch. Thanks to Hankin
793 <hankin@rogue.consultco.com> for this patch.
795 * Minor documentation fixes for MATCH FILES.
797 Version 0.2.2 changes since 0.2.1:
801 * Fix behavior of PRINT SPACE for negative arguments.
803 * Fix reading some unusual system files.
805 * Fix LIST problems with very long variables. Thanks to Hankin
806 <hankin@dunno.com> for this bug report.
