5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
9 * REGRESSION now recognises /STATISTICS=CI(x) which causes confidence
10 intervals for the coefficients to be printed.
12 * PSPPIRE graphical user interface improvements:
14 - File|Open now allows an encoding to be selected for opening
17 - File|Display Data File Information|External File... now allows an
18 encoding to be selected.
20 - A problem with the Means dialog has been resolved (bug #41433).
22 * System file related improvements:
24 - With ENCODING="DETECT", SYSFILE INFO can now help the user to
25 pick an encoding for reading a system file that does not identify
28 - SYSFILE INFO now accepts an ENCODING subcommand to specify the
29 character encoding of string data in the system file.
31 - System files that contain duplicate variable names may now be
32 read successfully (bug #41475).
34 Changes from 0.8.1 to 0.8.2:
36 * Charts are now rendered with colours from the Tango palette instead
37 of fully saturated primaries.
39 * Support for new system file variants:
41 - PSPP can now read and write ZCOMPRESSED system files, which
42 compress data much more effectively than older "compressed"
43 files. (The older format is still supported.)
45 - PSPP can now decrypt encrypted system files, using the new
46 pspp-convert utility. The encrypted system file format is
47 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
48 do not directly read or write this format.
50 * Missing values for long string variables are now read from and
51 written to system files in an SPSS-compatible fashion.
53 (Earlier versions of PSPP that supported missing values for long
54 string variables wrote them to system files in an SPSS-incompatible
55 way. To fix the problem, read the system file with this version of
56 PSPP and then save a new copy of it.)
58 * pspp-convert, a new standalone utility for converting SPSS system
59 and portable files to other formats, is now included. The initial
60 version supports comma-separated value files as output format.
61 pspp-convert can also decrypt encrypted system files.
65 - zlib is now a required dependency. (Previously it was optional.)
67 Changes from 0.8.0 to 0.8.1:
73 * Changes to existing commands:
75 - CROSSTABS: The requirement that one expected count must be less than five
76 before Fishers Exact Test will be reported has been removed.
78 * PSPPIRE graphical user interface improvements:
80 - A new set of icons has been contributed.
82 - Syntax windows now parse syntax in "auto" mode, which in practice
83 should mean that both "batch" and "interactive" syntax now works,
84 instead of just "interactive" syntax.
86 - The variable pane of data windows now include a Role column.
90 - System files written by IBM SPSS 21 are now read without warnings.
92 - System files written by "VOXCO INTERVIEWER 4.3" are now read
95 - PSPPIRE should now more gracefully handle syntax files that contain
98 Changes from 0.6.2 to 0.8.0:
104 - DATAFILE ATTRIBUTES
111 - LOGISTIC REGRESSION
115 - PRESERVE and RESTORE
119 - SAVE TRANSLATE to CSV and tab-delimited files
121 - VARIABLE ATTRIBUTES
123 * Changes to existing commands:
125 - AUTORECODE has a new GROUP subcommand.
127 - CROSSTABS has been re-implemented to fix numerous bugs.
129 - EXAMINE: /MISSING=LISTWISE is now the default.
131 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
132 contains an INCLUDE or INSERT command, substitutions are not
133 applied to the included file.
135 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
137 - HOST has been updated to use more modern syntax.
139 - Most commands that work with data files now support a new
142 - MISSING VALUES can now assign missing values to long string
145 - ONEWAY: the POSTHOC subcommand is now implemented.
147 - The following new subcommands to NPAR TESTS have been implemented:
148 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
149 MCNEMAR, SIGN, WILCOXON, and RUNS
151 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
152 DPROMPT subcommands. The defaults are now fixed values.
154 - SHOW now has a JOURNAL subcommand, to show the location of the
157 - VALUE LABELS can now assign value labels to long string
160 * Other language changes:
162 - The new DATASET commands replace the "scratch file" PSPP
163 extension, which is no longer supported.
165 - Strings may now include arbitrary Unicode code points specified
166 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
167 code point U+1D11E, the musical G clef character, may be
168 expressed as U'1D11E'.
170 See the "Tokens" section in the PSPP manual for more information.
172 - In previous versions of PSPP, in a string expressed in
173 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
174 bytes in the locale encoding. In this version of PSPP, X'hh'
175 syntax always expresses bytes in UTF-8 encoding.
177 See the "Tokens" section in the PSPP manual for more information.
179 * PSPPIRE graphical user interface improvements:
181 - Added support for non-ASCII characters in strings, labels and
184 - A "Split Window" function is available, which makes it easier to
185 see different parts of a large data file.
187 - Data files can now be opened by specifing their name as the first
188 argument. This means that on a properly configured desktop, double
189 clicking on an icon will open the file.
191 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
192 via using an "intelligent" application assistant dialog.
196 - The new "cairo" output driver supports output in PostScript, PDF,
197 and SVG formats. Its functionality is a superset of that of the
198 "postscript" driver, which has been removed. You must have Cairo
199 and Pango installed to build the "cairo" driver.
201 - Charts are now produced with Cairo and Pango, instead of libplot.
202 Without them, the new graphing features will not work. If you do
203 not have Cairo and Pango installed, you must run `configure' with
206 - The plain text output driver now properly supports multibyte UTF-8
207 characters, including double-width characters and combining
210 - Output to OpenDocument format is now supported.
212 - The HTML output is much improved.
214 * The "pspp" program has a new option --batch (or -b) that selects
215 "batch" syntax mode. In previous versions of PSPP this syntax mode
216 was the default. Now a new "auto" syntax mode is the default. In
217 "auto" mode, PSPP interprets most syntax files correctly regardless
218 of their intended syntax mode.
220 See the "Syntax Variants" section in the PSPP manual for more
223 * The "pspp" program has a new option --syntax-encoding that
224 specifies the encoding for syntax files listed on the command line,
225 as well as the default encoding for syntax files included with
226 INCLUDE or INSERT. The default is to accept the system locale
227 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
228 one the system file uses.
230 See the documentation for the INSERT command in the PSPP manual for
233 * Text data files that PRINT and WRITE creates now use the system
234 native line ends by default (CRLF on Windows, LF only elsewhere).
235 Use the new ENDS subcommand on FILE HANDLE to override the default.
237 * A new Perl module allows Perl programs to read and write PSPP
240 * A tutorial chapter has been added to the user manual.
242 Changes from 0.6.1 to 0.6.2:
246 - Dutch, thanks to Harry Thijssen.
248 - Brazilian Portuguese, thanks to Michel Boaventura.
250 Thanks for translations are also due to the coordinators at
251 translationproject.org.
253 * Statistical bug fixes:
255 - REGRESSION: Report correct standard error of the estimate (bug
258 - T-TEST: Report correct significance of paired sample T-test in
259 the common case (bug #26936) and corner cases. Thanks to Mike
260 Griffiths and Matej Cepl for reporting these bugs.
262 * Build fixes and changes:
264 - Fix build with GTK+ 2.17.4 and later.
266 - Make running "make" after running "configure" with different
267 settings reliably rebuild version.c.
269 - Cygwin and MinGW build fixes.
271 - Fixes for building with recent gnulib.
273 - The Makefile now honors two new variables, PSPP_LDFLAGS and
274 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
275 binaries, respectively. This makes building easier for some
278 - Fixes for "configure --enable-relocatable" (bug #25508).
280 * Data file bug fixes and changes:
282 - Fix reading text data files that contain a mix of white space
283 and commas. Now "a ,b" is treated as two fields containing "a"
284 and "b"; previously it was treated as three, with an empty field
287 - Fix writing corrupted .sav files on Windows.
289 - Fix writing variable labels longer than 252 bytes to save files.
290 Thanks to Robert Westlund for reporting this bug.
292 - Fix writing corrupted .por files (bug #26034).
294 - Fix reading .por files whose initial lines are not padded out
295 with spaces as expected.
297 - PSPP will no longer issue warnings about some .sav file records
298 or values that it does not understand. These warnings were
299 harmless, but needlessly alarmed some users.
301 - Fix crash reading empty string fields from PostgreSQL databases.
303 * Bug fixes that affect PSPP and PSPPIRE:
305 - Users may now control precision of output statistics. Instead
306 of hard coding the width and decimals of output numbers, respect
307 the default format in most instances. Counts are now normally
308 displayed with the format of the weight variable, if any.
310 - Fix crash when an INSERT command specifies the name of a file
311 that does not exist (bug #24569).
313 - Fix crash when CROSSTABS specifies a long-string variable (bugs
316 - Fix crash drawing pie charts with many segments.
318 - Fix crash when NUMERIC specifies an invalid format.
320 * PSPPIRE bug fixes and changes:
322 - On Windows, write the output file to the user's home directory
323 instead of the current directory, to better match user
326 - Some data editor fixes.
330 - Fix typo in BINOMIAL section of user manual (bug #25892).
332 Changes from 0.6.0 to 0.6.1:
334 * Statistical bug fixes:
336 - Report correct standardized regression coefficients in linear
337 regression output (bug #23567).
339 * Bug fixes that affect PSPP and PSPPIRE:
341 - Avoid crash with pie charts (bug #24014).
343 - Don't append % to count totals (bug #24003).
345 - Don't crash on bad input (bug #24031).
347 - Don't crash if "end data." is not left aligned (bug #24115).
349 - Change default workspace value to 64 MB, to avoid unnecessary
350 disk accesses on modern machines.
354 - Add ".sav" or ".por" suffix to filename when saving with Save_As
357 - Make it possible to reopen the output window on Windows (bug
360 - A POSIX regular expression library is now included and used
361 automatically if the host does not have one or has one that is
364 * Build fixes and changes:
366 - Work around bug in GSL that prevented build with recent GCC
367 versions without manually adding -fgnu89-inline to CFLAGS.
369 - Also warn about missing prerequisites as we encounter them (bug
372 - Distribute necessary files to allow users working from the
373 distributed tarball to configure with --enable-gui-tools.
375 - Append $(EXEEXT_FOR_BUILD) to output file name when building
376 q2c, fixing build problems on Windows.
378 - GSL 1.8 or later is now required.
380 - Build errors with --enable-relocatable were fixed.
382 * The German translations were removed, since native German speakers
383 found them too poor to be useful.
385 Changes from 0.4.0 to 0.6.0:
387 * The PSPP license is now version 3 or later of the GNU General
388 Public License. Previously, it was version 2 or later.
390 * PSPP now has a graphical interface, called PSPPIRE. This
391 interface allows you to enter data and variable definitions
392 interactively. Commands may be executed in syntax form, or by
393 using the interactive dialog boxes available from the dropdown
396 * A few sample syntax files are now included in the `examples'
399 * Numerous major and minor bugs have been fixed.
403 * The INSTALL file now reflects the details of how to install
404 PSPP. It is a tailored version of the generic installation
405 instructions, instead of a verbatim copy.
407 * iconv, which is ordinarily installed as part of a Unix-like
408 system, is now required. If you don't have it already, you can
409 install GNU libiconv (http://www.gnu.org/software/libiconv/).
411 * libxml2 and zlib are new optional dependencies. They are
412 required to use PSPP's support for reading Gnumeric files.
414 Statistical procedure changes:
416 * REGRESSION is a new procedure for fitting linear models to data
417 via least-squares estimation.
419 * NPAR TESTS is a new procedure for non-parametric tests. In this
420 release, it supports binomial and chi-square tests.
422 * RANK is a new procedure to rank variables. It supports numerous
425 * FREQUENCIES can now output histograms and pie charts. These
426 features were present in earlier releases, but not documented.
428 User interface changes:
430 * In many situations where PSPP once terminated with a fatal
431 error, PSPP now recovers and continues execution.
433 * PSPP is now able to start up and run even if it cannot find its
436 * Journaling of interactive commands to a disk file is now
437 implemented. By default, journaling is enabled, to a file named
438 `pspp.jnl' in the current directory. SET JOURNAL may be used to
441 * The use of `+' between syntax file names on the command line to
442 prevent the dictionary from being cleared between their
443 executions is no longer supported. All syntax files are now
444 executed as if `+' had been specified.
446 * The -d/--define and -u/--undef command line options are no
447 longer supported. Instead, use /usr/bin/env or shell primitives
448 to define or clear environment variables before invoking PSPP.
450 * If a syntax file named named `rc' is found in a configuration
451 directory (such as $HOME/.pspp), it is executed before any
452 syntax file specified on the command line. The -r or
453 --no-statrc command line option may be used to disable this
458 * Output configuration options have changed. Please refer to the
459 manual for a full description of the available options.
461 In consequence, you will need to reinstall your "devices" file.
462 "make install" will do this for you.
464 * Most error messages are now written to PSPP output files by
465 default. SET ERROR can be used to disable this behavior.
467 * When invoked interactively, PSPP now by default produces output
468 on the terminal, piping it through the "more" program.
469 Previously, by default output was written only to file
470 pspp.list. On most terminals, the page length used for output
471 automatically adapts to the terminal size, even if the terminal
476 - This driver now supports charts in output. Charts are written
477 as separate files that the main output file refers to. By
478 default, charts are written in PNG format to files named
479 pspp-1.png, pspp-2.png, and so on.
481 - Configurations are provided that use VT100 (and xterm)
482 line-drawing characters in tables. The option "-o list-vt100"
483 requests use of this device for output to pspp.list.
487 - The default paper size is now determined using the PAPERSIZE
488 environment variable, or the LC_PAPER locale category on
489 systems that support it. If these are not set, the default is
490 now A4, instead of US letter. To make US letter the default,
491 set PAPERSIZE to "letter" in your environment.
493 - Font metrics are now read from AFM files, instead of
494 Groff-format metrics files. PostScript fonts can now be
497 In consequence, you will need to install an AFM file for each
498 font used in PostScript output. "make install" will install
499 AFM files for the standard PostScript fonts, including the
500 ones that the PostScript driver uses by default.
502 - Standard paper sizes no longer need to be specified through a
503 configuration file. The "papersize" configuration file is no
504 longer needed, or supported.
506 - The PostScript prologue is no longer obtained from the
507 "ps-prologue" configuration file. This configuration file is
508 no longer needed, or supported.
512 - The HTML prologue is no longer obtained from the
513 "html-prologue" configuration file. This configuration file
514 is no longer needed, or supported.
516 Command language changes:
518 * The following commands are new:
520 - GET DATA, which currently supports reading Gnumeric files and
521 text data files. It will be extended later to read other
522 types of foreign data.
524 - CD, to change the current directory.
526 - INSERT, to execute a syntax file.
528 - DELETE VARIABLES, to remove variables from the active file
531 - ADD DOCUMENT, to add text to active file documents.
533 - CLOSE FILE HANDLE (a PSPP extension; see below).
535 - XEXPORT, a PSPP extension that is a transformation equivalent
538 * The following functions for transformation expressions are new:
540 - DATEDIFF, for computing the difference of two dates.
542 - DATESUM, for advancing a date by a specified duration.
544 - VALUELABEL, to obtain the value label for a value.
546 * PSPP now supports very long string variables (over 255 bytes
549 * MATCH FILES now supports the FIRST and LAST subcommands.
551 * Previous versions of PSPP prohibited using commands to both read and
552 write a single file at the same time. Now, PSPP allows this, and
553 the new version of the file atomically replaces the old version.
555 * The following commands are no longer available. They will be
556 re-implemented in a later release:
558 - CLEAR TRANSFORMATIONS
564 * The PROCESS IF command, which was deprecated, has been removed.
565 You may replace any usage of it by SELECT IF following
566 TEMPORARY, which has the same effect.
568 * The output format for variables created by VECTOR may now be
569 specified as part of the VECTOR syntax.
571 "Scratch files", a new PSPP extension:
573 A scratch file, like a system file, consists of a dictionary and
574 any number of cases. Small scratch files are stored in memory;
575 one that grows too large is written to disk. By default, any file
576 handle whose name begins with # is assumed to refer to a scratch
579 Scratch files can be used just about anywhere a system or portable
580 file can be used. Also, portable files are now allowed in most
581 places that system files were allowed in previous PSPP version.
583 A new CLOSE FILE HANDLE command allows the storage associated with
584 scratch files to be freed. It also allows file handles to be
585 reassigned to new files.
587 For more information on scratch files, refer to the "File Handles"
588 section in the PSPP manual. For specifics of what commands now
589 allow what kinds of files to be specified, refer to the
590 documentation on those particular commands.
594 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
595 translation, are now supported. Use FILE HANDLE to specify the
596 format of these files.
598 * Little-endian, big-endian, and VAX-endian formats are now
599 supported for integer binary formats when reading and writing
600 data files. The new RIB and WIB subcommands on the SET command
601 control endianness of integer data. The default is the host's
604 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
605 floating point binary formats when reading and writing data
606 files. The new RRB and WRB subcommands on the SET command
607 control the floating point format. The default is the host's
608 native floating point format.
610 * DATA LIST now supports the SKIP subcommand, to skip records at
611 the beginning of a file. For compatibility, DATA LIST now
612 treats N format as F format for FREE and LIST format input.
614 * The SAVE and XSAVE commands now support the UNSELECTED,
615 PERMISSIONS, NAMES, and MAP subcommands.
617 * The EXPORT command has been re-implemented to obtain better
618 results. Support for the UNSELECTED, DIGITS, and TYPE
619 subcommands has been added.
621 * For compatibility, PRINT now inserts a space at the beginning of
622 every output line, even lines that would otherwise be blank,
623 when OUTFILE is specified. (The behavior of WRITE is
626 * For compatibility, PRINT EJECT now inserts the digit `1' at the
627 beginning of each line that should begin a new page.
629 * For compatibility, WRITE now outputs the system-missing value as
630 a field filled with spaces. Binary formats are an exception.
631 (The behavior of PRINT is unchanged.)
635 * Input and output format descriptions have been rewritten. They
636 now precisely describe what is accepted on input and written on
639 * The descriptions of the PSPP system and portable file formats
640 have been extensively revised and improved.
642 For developers, the build system now requires Autoconf 2.60 and
645 Changes from 0.3.0 to 0.4.0:
647 Changes in build dependencies:
649 * The GNU Scientific Library (libgsl), version 1.6 or later, is
652 * libplot from GNU plotutils is optional. Without it, the new
653 graphing features will not work. If you do not have it
654 installed, you must run `configure' with --without-libplot.
656 * libgmp2 is no longer a dependency.
658 Newly implemented commands and statistical features:
660 * EXAMINE, including its graphing features.
662 * FREQUENCIES now supports percentiles.
670 * SORT CASES now sorts stably, that is, two cases with equal sort
671 criteria will be in the same relative order before and after the
674 * T-TEST (re-written).
676 * DATE and USE. These commands are parsed but otherwise ignored,
677 to enhance compatibility with certain command files that invoke
680 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
681 currently have no effect on PSPP output, but their values are
682 written to and read from system files and thus may affect
683 third-party software.
685 * SET EPOCH implemented.
687 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
690 * FILE HANDLE now supports custom tab widths.
692 Long variable names (and other identifiers) are now supported. Up
693 to the first 64 bytes of each identifier is significant. PSPP now
694 reads and writes system files compatible with SPSS version 12.
696 New --algorithm and --syntax command line options allow
697 SPSS-compatible or enhanced modes to be selected.
699 Support for transformation expressions has been rewritten and
700 significantly improved. Refer to the manual for details.
702 Calculation of moments (mean, standard deviation, kurtosis,
703 skewness) has been rewritten and should now be more accurate. In
704 --algorithm=enhanced mode moments may be more accurate than SPSS in
707 Numerous bugs have been fixed, too many to mention here. Many new
708 tests have been added, leading to the discovery and fixing of many
711 The ASCII output driver can now squeeze multiple blank lines into
714 Much of the code has been rewritten and refactored. It is now much
717 The FILE TYPE and REPEATING DATA commands have been disabled for
718 this release because their implementations were deemed too buggy to
719 be useful. They will be fixed and replaced in a future release.
721 New pspp-mode for Emacs (in pspp-mode.el).
723 Added rudimentary command-line completion for interactive input.
725 lib/julcal and lib/dcdflib are no longer used, so they have been
728 For developers, the build system now requires Autoconf 2.58 and
729 Automake 1.7. The included gettext has been updated to version
732 Some reports state that Texinfo 4.8, the latest version, may be
733 necessary to successfully format the documentation on some systems.
735 Version 0.3.0 changes since 0.2.3:
739 * Using alphanumeric variables in functions under AGGREGATE
742 * Under certain circumstances, the final case would be omitted
743 from the results of an AGGREGATE operation. Fixed.
745 * Undefined behavior was invoked by referencing a freed pointer
746 under certain circumstances. Fixed.
748 * A wrong record size was displayed when paging the active file to
751 * Not having enough temporary space for sorting caused a core
754 * Syntax errors in function descriptions on AGGREGATE caused core
757 * A null pointer was dereferenced, causing a core dump, when
758 PERCENTILES was specified on FREQUENCIES. This fixes the
759 problem, but PSPP still doesn't calculate percentiles.
761 * SORT always sorted in ascending order. Fixed.
763 * Some minor memory leaks in the expression parser were removed.
765 * Many assertions fixed for strict ANSI C compliance.
769 * SET ECHO ON now implemented, but turned off by default.
771 * PRINT specifier supported on END REPEAT.
775 * System libgmp2 library is used if installed instead of
776 unconditionally using the included libgmp2 subset.
778 * Extensive code cleanup, which continues.
780 * Added CORRELATIONS command parser, but not implemented.
782 Version 0.2.3 changes since 0.2.2:
786 * SPLIT FILE with a string variable caused a core dump. Fixed.
788 * Nested INCLUDEs didn't work. Fixed.
790 * The MATCH FILES procedure set the values of variables not present
791 to 0. It should have been SYSMIS. This is now fixed.
793 * The REMARK command was too aggressive about skipping lines. It
794 didn't like being the last command in a file.
796 * Comment parsing wasn't consistent with the rest of the code in its
797 idea of where one command ends and another starts. This meant
798 that sometimes commands would be mysteriously ignored. Thanks to
799 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
801 * The TABLE subcommand on MATCH FILES worked only erratically at
802 best. This fixes it. Thanks to Dr. Dirk Melcher
803 <BZN-mdksh@t-online.de> for reporting this bug.
805 * VARIABLE LABELS rejected a slash before the first variable
806 specification, contradicting the documentation. Thanks to Walter
807 M. Gray <graywm@northernc.on.ca> for reporting this bug.
809 * Because of an incorrect optimization in memory allocation,
810 CROSSTABS sometimes segfaulted when asked to output multiple
