5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
9 * Charts are now rendered with colours from the Tango palette instead
10 of fully saturated primaries.
12 * Missing values for long string variables are now read from and
13 written to system files in an SPSS-compatible fashion.
15 (Earlier versions of PSPP that supported missing values for long
16 string variables wrote them to system files in an SPSS-incompatible
17 way. To fix the problem, read the system file with this version of
18 PSPP and then save a new copy of it.)
22 - zlib is now a required dependency. (Previously it was optional.)
24 Changes from 0.8.0 to 0.8.1:
30 * Changes to existing commands:
32 - CROSSTABS: The requirement that one expected count must be less than five
33 before Fishers Exact Test will be reported has been removed.
35 * PSPPIRE graphical user interface improvements:
37 - A new set of icons has been contributed.
39 - Syntax windows now parse syntax in "auto" mode, which in practice
40 should mean that both "batch" and "interactive" syntax now works,
41 instead of just "interactive" syntax.
43 - The variable pane of data windows now include a Role column.
47 - System files written by IBM SPSS 21 are now read without warnings.
49 - System files written by "VOXCO INTERVIEWER 4.3" are now read
52 - PSPPIRE should now more gracefully handle syntax files that contain
55 Changes from 0.6.2 to 0.8.0:
72 - PRESERVE and RESTORE
76 - SAVE TRANSLATE to CSV and tab-delimited files
80 * Changes to existing commands:
82 - AUTORECODE has a new GROUP subcommand.
84 - CROSSTABS has been re-implemented to fix numerous bugs.
86 - EXAMINE: /MISSING=LISTWISE is now the default.
88 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
89 contains an INCLUDE or INSERT command, substitutions are not
90 applied to the included file.
92 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
94 - HOST has been updated to use more modern syntax.
96 - Most commands that work with data files now support a new
99 - MISSING VALUES can now assign missing values to long string
102 - ONEWAY: the POSTHOC subcommand is now implemented.
104 - The following new subcommands to NPAR TESTS have been implemented:
105 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
106 MCNEMAR, SIGN, WILCOXON, and RUNS
108 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
109 DPROMPT subcommands. The defaults are now fixed values.
111 - SHOW now has a JOURNAL subcommand, to show the location of the
114 - VALUE LABELS can now assign value labels to long string
117 * Other language changes:
119 - The new DATASET commands replace the "scratch file" PSPP
120 extension, which is no longer supported.
122 - Strings may now include arbitrary Unicode code points specified
123 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
124 code point U+1D11E, the musical G clef character, may be
125 expressed as U'1D11E'.
127 See the "Tokens" section in the PSPP manual for more information.
129 - In previous versions of PSPP, in a string expressed in
130 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
131 bytes in the locale encoding. In this version of PSPP, X'hh'
132 syntax always expresses bytes in UTF-8 encoding.
134 See the "Tokens" section in the PSPP manual for more information.
136 * PSPPIRE graphical user interface improvements:
138 - Added support for non-ASCII characters in strings, labels and
141 - A "Split Window" function is available, which makes it easier to
142 see different parts of a large data file.
144 - Data files can now be opened by specifing their name as the first
145 argument. This means that on a properly configured desktop, double
146 clicking on an icon will open the file.
148 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
149 via using an "intelligent" application assistant dialog.
153 - The new "cairo" output driver supports output in PostScript, PDF,
154 and SVG formats. Its functionality is a superset of that of the
155 "postscript" driver, which has been removed. You must have Cairo
156 and Pango installed to build the "cairo" driver.
158 - Charts are now produced with Cairo and Pango, instead of libplot.
159 Without them, the new graphing features will not work. If you do
160 not have Cairo and Pango installed, you must run `configure' with
163 - The plain text output driver now properly supports multibyte UTF-8
164 characters, including double-width characters and combining
167 - Output to OpenDocument format is now supported.
169 - The HTML output is much improved.
171 * The "pspp" program has a new option --batch (or -b) that selects
172 "batch" syntax mode. In previous versions of PSPP this syntax mode
173 was the default. Now a new "auto" syntax mode is the default. In
174 "auto" mode, PSPP interprets most syntax files correctly regardless
175 of their intended syntax mode.
177 See the "Syntax Variants" section in the PSPP manual for more
180 * The "pspp" program has a new option --syntax-encoding that
181 specifies the encoding for syntax files listed on the command line,
182 as well as the default encoding for syntax files included with
183 INCLUDE or INSERT. The default is to accept the system locale
184 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
185 one the system file uses.
187 See the documentation for the INSERT command in the PSPP manual for
190 * Text data files that PRINT and WRITE creates now use the system
191 native line ends by default (CRLF on Windows, LF only elsewhere).
192 Use the new ENDS subcommand on FILE HANDLE to override the default.
194 * A new Perl module allows Perl programs to read and write PSPP
197 * A tutorial chapter has been added to the user manual.
199 Changes from 0.6.1 to 0.6.2:
203 - Dutch, thanks to Harry Thijssen.
205 - Brazilian Portuguese, thanks to Michel Boaventura.
207 Thanks for translations are also due to the coordinators at
208 translationproject.org.
210 * Statistical bug fixes:
212 - REGRESSION: Report correct standard error of the estimate (bug
215 - T-TEST: Report correct significance of paired sample T-test in
216 the common case (bug #26936) and corner cases. Thanks to Mike
217 Griffiths and Matej Cepl for reporting these bugs.
219 * Build fixes and changes:
221 - Fix build with GTK+ 2.17.4 and later.
223 - Make running "make" after running "configure" with different
224 settings reliably rebuild version.c.
226 - Cygwin and MinGW build fixes.
228 - Fixes for building with recent gnulib.
230 - The Makefile now honors two new variables, PSPP_LDFLAGS and
231 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
232 binaries, respectively. This makes building easier for some
235 - Fixes for "configure --enable-relocatable" (bug #25508).
237 * Data file bug fixes and changes:
239 - Fix reading text data files that contain a mix of white space
240 and commas. Now "a ,b" is treated as two fields containing "a"
241 and "b"; previously it was treated as three, with an empty field
244 - Fix writing corrupted .sav files on Windows.
246 - Fix writing variable labels longer than 252 bytes to save files.
247 Thanks to Robert Westlund for reporting this bug.
249 - Fix writing corrupted .por files (bug #26034).
251 - Fix reading .por files whose initial lines are not padded out
252 with spaces as expected.
254 - PSPP will no longer issue warnings about some .sav file records
255 or values that it does not understand. These warnings were
256 harmless, but needlessly alarmed some users.
258 - Fix crash reading empty string fields from PostgreSQL databases.
260 * Bug fixes that affect PSPP and PSPPIRE:
262 - Users may now control precision of output statistics. Instead
263 of hard coding the width and decimals of output numbers, respect
264 the default format in most instances. Counts are now normally
265 displayed with the format of the weight variable, if any.
267 - Fix crash when an INSERT command specifies the name of a file
268 that does not exist (bug #24569).
270 - Fix crash when CROSSTABS specifies a long-string variable (bugs
273 - Fix crash drawing pie charts with many segments.
275 - Fix crash when NUMERIC specifies an invalid format.
277 * PSPPIRE bug fixes and changes:
279 - On Windows, write the output file to the user's home directory
280 instead of the current directory, to better match user
283 - Some data editor fixes.
287 - Fix typo in BINOMIAL section of user manual (bug #25892).
289 Changes from 0.6.0 to 0.6.1:
291 * Statistical bug fixes:
293 - Report correct standardized regression coefficients in linear
294 regression output (bug #23567).
296 * Bug fixes that affect PSPP and PSPPIRE:
298 - Avoid crash with pie charts (bug #24014).
300 - Don't append % to count totals (bug #24003).
302 - Don't crash on bad input (bug #24031).
304 - Don't crash if "end data." is not left aligned (bug #24115).
306 - Change default workspace value to 64 MB, to avoid unnecessary
307 disk accesses on modern machines.
311 - Add ".sav" or ".por" suffix to filename when saving with Save_As
314 - Make it possible to reopen the output window on Windows (bug
317 - A POSIX regular expression library is now included and used
318 automatically if the host does not have one or has one that is
321 * Build fixes and changes:
323 - Work around bug in GSL that prevented build with recent GCC
324 versions without manually adding -fgnu89-inline to CFLAGS.
326 - Also warn about missing prerequisites as we encounter them (bug
329 - Distribute necessary files to allow users working from the
330 distributed tarball to configure with --enable-gui-tools.
332 - Append $(EXEEXT_FOR_BUILD) to output file name when building
333 q2c, fixing build problems on Windows.
335 - GSL 1.8 or later is now required.
337 - Build errors with --enable-relocatable were fixed.
339 * The German translations were removed, since native German speakers
340 found them too poor to be useful.
342 Changes from 0.4.0 to 0.6.0:
344 * The PSPP license is now version 3 or later of the GNU General
345 Public License. Previously, it was version 2 or later.
347 * PSPP now has a graphical interface, called PSPPIRE. This
348 interface allows you to enter data and variable definitions
349 interactively. Commands may be executed in syntax form, or by
350 using the interactive dialog boxes available from the dropdown
353 * A few sample syntax files are now included in the `examples'
356 * Numerous major and minor bugs have been fixed.
360 * The INSTALL file now reflects the details of how to install
361 PSPP. It is a tailored version of the generic installation
362 instructions, instead of a verbatim copy.
364 * iconv, which is ordinarily installed as part of a Unix-like
365 system, is now required. If you don't have it already, you can
366 install GNU libiconv (http://www.gnu.org/software/libiconv/).
368 * libxml2 and zlib are new optional dependencies. They are
369 required to use PSPP's support for reading Gnumeric files.
371 Statistical procedure changes:
373 * REGRESSION is a new procedure for fitting linear models to data
374 via least-squares estimation.
376 * NPAR TESTS is a new procedure for non-parametric tests. In this
377 release, it supports binomial and chi-square tests.
379 * RANK is a new procedure to rank variables. It supports numerous
382 * FREQUENCIES can now output histograms and pie charts. These
383 features were present in earlier releases, but not documented.
385 User interface changes:
387 * In many situations where PSPP once terminated with a fatal
388 error, PSPP now recovers and continues execution.
390 * PSPP is now able to start up and run even if it cannot find its
393 * Journaling of interactive commands to a disk file is now
394 implemented. By default, journaling is enabled, to a file named
395 `pspp.jnl' in the current directory. SET JOURNAL may be used to
398 * The use of `+' between syntax file names on the command line to
399 prevent the dictionary from being cleared between their
400 executions is no longer supported. All syntax files are now
401 executed as if `+' had been specified.
403 * The -d/--define and -u/--undef command line options are no
404 longer supported. Instead, use /usr/bin/env or shell primitives
405 to define or clear environment variables before invoking PSPP.
407 * If a syntax file named named `rc' is found in a configuration
408 directory (such as $HOME/.pspp), it is executed before any
409 syntax file specified on the command line. The -r or
410 --no-statrc command line option may be used to disable this
415 * Output configuration options have changed. Please refer to the
416 manual for a full description of the available options.
418 In consequence, you will need to reinstall your "devices" file.
419 "make install" will do this for you.
421 * Most error messages are now written to PSPP output files by
422 default. SET ERROR can be used to disable this behavior.
424 * When invoked interactively, PSPP now by default produces output
425 on the terminal, piping it through the "more" program.
426 Previously, by default output was written only to file
427 pspp.list. On most terminals, the page length used for output
428 automatically adapts to the terminal size, even if the terminal
433 - This driver now supports charts in output. Charts are written
434 as separate files that the main output file refers to. By
435 default, charts are written in PNG format to files named
436 pspp-1.png, pspp-2.png, and so on.
438 - Configurations are provided that use VT100 (and xterm)
439 line-drawing characters in tables. The option "-o list-vt100"
440 requests use of this device for output to pspp.list.
444 - The default paper size is now determined using the PAPERSIZE
445 environment variable, or the LC_PAPER locale category on
446 systems that support it. If these are not set, the default is
447 now A4, instead of US letter. To make US letter the default,
448 set PAPERSIZE to "letter" in your environment.
450 - Font metrics are now read from AFM files, instead of
451 Groff-format metrics files. PostScript fonts can now be
454 In consequence, you will need to install an AFM file for each
455 font used in PostScript output. "make install" will install
456 AFM files for the standard PostScript fonts, including the
457 ones that the PostScript driver uses by default.
459 - Standard paper sizes no longer need to be specified through a
460 configuration file. The "papersize" configuration file is no
461 longer needed, or supported.
463 - The PostScript prologue is no longer obtained from the
464 "ps-prologue" configuration file. This configuration file is
465 no longer needed, or supported.
469 - The HTML prologue is no longer obtained from the
470 "html-prologue" configuration file. This configuration file
471 is no longer needed, or supported.
473 Command language changes:
475 * The following commands are new:
477 - GET DATA, which currently supports reading Gnumeric files and
478 text data files. It will be extended later to read other
479 types of foreign data.
481 - CD, to change the current directory.
483 - INSERT, to execute a syntax file.
485 - DELETE VARIABLES, to remove variables from the active file
488 - ADD DOCUMENT, to add text to active file documents.
490 - CLOSE FILE HANDLE (a PSPP extension; see below).
492 - XEXPORT, a PSPP extension that is a transformation equivalent
495 * The following functions for transformation expressions are new:
497 - DATEDIFF, for computing the difference of two dates.
499 - DATESUM, for advancing a date by a specified duration.
501 - VALUELABEL, to obtain the value label for a value.
503 * PSPP now supports very long string variables (over 255 bytes
506 * MATCH FILES now supports the FIRST and LAST subcommands.
508 * Previous versions of PSPP prohibited using commands to both read and
509 write a single file at the same time. Now, PSPP allows this, and
510 the new version of the file atomically replaces the old version.
512 * The following commands are no longer available. They will be
513 re-implemented in a later release:
515 - CLEAR TRANSFORMATIONS
521 * The PROCESS IF command, which was deprecated, has been removed.
522 You may replace any usage of it by SELECT IF following
523 TEMPORARY, which has the same effect.
525 * The output format for variables created by VECTOR may now be
526 specified as part of the VECTOR syntax.
528 "Scratch files", a new PSPP extension:
530 A scratch file, like a system file, consists of a dictionary and
531 any number of cases. Small scratch files are stored in memory;
532 one that grows too large is written to disk. By default, any file
533 handle whose name begins with # is assumed to refer to a scratch
536 Scratch files can be used just about anywhere a system or portable
537 file can be used. Also, portable files are now allowed in most
538 places that system files were allowed in previous PSPP version.
540 A new CLOSE FILE HANDLE command allows the storage associated with
541 scratch files to be freed. It also allows file handles to be
542 reassigned to new files.
544 For more information on scratch files, refer to the "File Handles"
545 section in the PSPP manual. For specifics of what commands now
546 allow what kinds of files to be specified, refer to the
547 documentation on those particular commands.
551 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
552 translation, are now supported. Use FILE HANDLE to specify the
553 format of these files.
555 * Little-endian, big-endian, and VAX-endian formats are now
556 supported for integer binary formats when reading and writing
557 data files. The new RIB and WIB subcommands on the SET command
558 control endianness of integer data. The default is the host's
561 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
562 floating point binary formats when reading and writing data
563 files. The new RRB and WRB subcommands on the SET command
564 control the floating point format. The default is the host's
565 native floating point format.
567 * DATA LIST now supports the SKIP subcommand, to skip records at
568 the beginning of a file. For compatibility, DATA LIST now
569 treats N format as F format for FREE and LIST format input.
571 * The SAVE and XSAVE commands now support the UNSELECTED,
572 PERMISSIONS, NAMES, and MAP subcommands.
574 * The EXPORT command has been re-implemented to obtain better
575 results. Support for the UNSELECTED, DIGITS, and TYPE
576 subcommands has been added.
578 * For compatibility, PRINT now inserts a space at the beginning of
579 every output line, even lines that would otherwise be blank,
580 when OUTFILE is specified. (The behavior of WRITE is
583 * For compatibility, PRINT EJECT now inserts the digit `1' at the
584 beginning of each line that should begin a new page.
586 * For compatibility, WRITE now outputs the system-missing value as
587 a field filled with spaces. Binary formats are an exception.
588 (The behavior of PRINT is unchanged.)
592 * Input and output format descriptions have been rewritten. They
593 now precisely describe what is accepted on input and written on
596 * The descriptions of the PSPP system and portable file formats
597 have been extensively revised and improved.
599 For developers, the build system now requires Autoconf 2.60 and
602 Changes from 0.3.0 to 0.4.0:
604 Changes in build dependencies:
606 * The GNU Scientific Library (libgsl), version 1.6 or later, is
609 * libplot from GNU plotutils is optional. Without it, the new
610 graphing features will not work. If you do not have it
611 installed, you must run `configure' with --without-libplot.
613 * libgmp2 is no longer a dependency.
615 Newly implemented commands and statistical features:
617 * EXAMINE, including its graphing features.
619 * FREQUENCIES now supports percentiles.
627 * SORT CASES now sorts stably, that is, two cases with equal sort
628 criteria will be in the same relative order before and after the
631 * T-TEST (re-written).
633 * DATE and USE. These commands are parsed but otherwise ignored,
634 to enhance compatibility with certain command files that invoke
637 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
638 currently have no effect on PSPP output, but their values are
639 written to and read from system files and thus may affect
640 third-party software.
642 * SET EPOCH implemented.
644 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
647 * FILE HANDLE now supports custom tab widths.
649 Long variable names (and other identifiers) are now supported. Up
650 to the first 64 bytes of each identifier is significant. PSPP now
651 reads and writes system files compatible with SPSS version 12.
653 New --algorithm and --syntax command line options allow
654 SPSS-compatible or enhanced modes to be selected.
656 Support for transformation expressions has been rewritten and
657 significantly improved. Refer to the manual for details.
659 Calculation of moments (mean, standard deviation, kurtosis,
660 skewness) has been rewritten and should now be more accurate. In
661 --algorithm=enhanced mode moments may be more accurate than SPSS in
664 Numerous bugs have been fixed, too many to mention here. Many new
665 tests have been added, leading to the discovery and fixing of many
668 The ASCII output driver can now squeeze multiple blank lines into
671 Much of the code has been rewritten and refactored. It is now much
674 The FILE TYPE and REPEATING DATA commands have been disabled for
675 this release because their implementations were deemed too buggy to
676 be useful. They will be fixed and replaced in a future release.
678 New pspp-mode for Emacs (in pspp-mode.el).
680 Added rudimentary command-line completion for interactive input.
682 lib/julcal and lib/dcdflib are no longer used, so they have been
685 For developers, the build system now requires Autoconf 2.58 and
686 Automake 1.7. The included gettext has been updated to version
689 Some reports state that Texinfo 4.8, the latest version, may be
690 necessary to successfully format the documentation on some systems.
692 Version 0.3.0 changes since 0.2.3:
696 * Using alphanumeric variables in functions under AGGREGATE
699 * Under certain circumstances, the final case would be omitted
700 from the results of an AGGREGATE operation. Fixed.
702 * Undefined behavior was invoked by referencing a freed pointer
703 under certain circumstances. Fixed.
705 * A wrong record size was displayed when paging the active file to
708 * Not having enough temporary space for sorting caused a core
711 * Syntax errors in function descriptions on AGGREGATE caused core
714 * A null pointer was dereferenced, causing a core dump, when
715 PERCENTILES was specified on FREQUENCIES. This fixes the
716 problem, but PSPP still doesn't calculate percentiles.
718 * SORT always sorted in ascending order. Fixed.
720 * Some minor memory leaks in the expression parser were removed.
722 * Many assertions fixed for strict ANSI C compliance.
726 * SET ECHO ON now implemented, but turned off by default.
728 * PRINT specifier supported on END REPEAT.
732 * System libgmp2 library is used if installed instead of
733 unconditionally using the included libgmp2 subset.
735 * Extensive code cleanup, which continues.
737 * Added CORRELATIONS command parser, but not implemented.
739 Version 0.2.3 changes since 0.2.2:
743 * SPLIT FILE with a string variable caused a core dump. Fixed.
745 * Nested INCLUDEs didn't work. Fixed.
747 * The MATCH FILES procedure set the values of variables not present
748 to 0. It should have been SYSMIS. This is now fixed.
750 * The REMARK command was too aggressive about skipping lines. It
751 didn't like being the last command in a file.
753 * Comment parsing wasn't consistent with the rest of the code in its
754 idea of where one command ends and another starts. This meant
755 that sometimes commands would be mysteriously ignored. Thanks to
756 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
758 * The TABLE subcommand on MATCH FILES worked only erratically at
759 best. This fixes it. Thanks to Dr. Dirk Melcher
760 <BZN-mdksh@t-online.de> for reporting this bug.
762 * VARIABLE LABELS rejected a slash before the first variable
763 specification, contradicting the documentation. Thanks to Walter
764 M. Gray <graywm@northernc.on.ca> for reporting this bug.
766 * Because of an incorrect optimization in memory allocation,
767 CROSSTABS sometimes segfaulted when asked to output multiple
768 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
771 * CROSSTABS didn't display value labels for column and row
772 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
775 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
776 <BZN-mdksh@t-online.de> for reporting this bug.
778 * The TABLE subcommand on MATCH FILES worked only erratically at
779 best. This fixes it. Thanks to Dr. Dirk Melcher
780 <BZN-mdksh@t-online.de> for reporting this bug.
782 * VARIABLE LABELS rejected a slash before the first variable
783 specification, contradicting the documentation. Thanks to Walter
784 M. Gray <graywm@northernc.on.ca> for reporting this bug.
786 * Because of an incorrect optimization in memory allocation,
787 CROSSTABS sometimes segfaulted when asked to output multiple
788 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
791 * CROSSTABS didn't display value labels for column and row
792 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
795 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
796 <BZN-mdksh@t-online.de> for reporting this bug.
798 * MATCH FILES corrupted memory and dumped core on some syntax
801 * MATCH FILES should set numeric values not available to the
802 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
803 <BZN-mdksh@t-online.de> for reporting this bug.
805 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
