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 * PSPP can now read and write ZCOMPRESSED system files, a new format
13 variant that compresses data much more effectively than the
14 previous form of compression (which is still supported).
16 * Missing values for long string variables are now read from and
17 written to system files in an SPSS-compatible fashion.
19 (Earlier versions of PSPP that supported missing values for long
20 string variables wrote them to system files in an SPSS-incompatible
21 way. To fix the problem, read the system file with this version of
22 PSPP and then save a new copy of it.)
26 - zlib is now a required dependency. (Previously it was optional.)
28 Changes from 0.8.0 to 0.8.1:
34 * Changes to existing commands:
36 - CROSSTABS: The requirement that one expected count must be less than five
37 before Fishers Exact Test will be reported has been removed.
39 * PSPPIRE graphical user interface improvements:
41 - A new set of icons has been contributed.
43 - Syntax windows now parse syntax in "auto" mode, which in practice
44 should mean that both "batch" and "interactive" syntax now works,
45 instead of just "interactive" syntax.
47 - The variable pane of data windows now include a Role column.
51 - System files written by IBM SPSS 21 are now read without warnings.
53 - System files written by "VOXCO INTERVIEWER 4.3" are now read
56 - PSPPIRE should now more gracefully handle syntax files that contain
59 Changes from 0.6.2 to 0.8.0:
76 - PRESERVE and RESTORE
80 - SAVE TRANSLATE to CSV and tab-delimited files
84 * Changes to existing commands:
86 - AUTORECODE has a new GROUP subcommand.
88 - CROSSTABS has been re-implemented to fix numerous bugs.
90 - EXAMINE: /MISSING=LISTWISE is now the default.
92 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
93 contains an INCLUDE or INSERT command, substitutions are not
94 applied to the included file.
96 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
98 - HOST has been updated to use more modern syntax.
100 - Most commands that work with data files now support a new
103 - MISSING VALUES can now assign missing values to long string
106 - ONEWAY: the POSTHOC subcommand is now implemented.
108 - The following new subcommands to NPAR TESTS have been implemented:
109 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
110 MCNEMAR, SIGN, WILCOXON, and RUNS
112 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
113 DPROMPT subcommands. The defaults are now fixed values.
115 - SHOW now has a JOURNAL subcommand, to show the location of the
118 - VALUE LABELS can now assign value labels to long string
121 * Other language changes:
123 - The new DATASET commands replace the "scratch file" PSPP
124 extension, which is no longer supported.
126 - Strings may now include arbitrary Unicode code points specified
127 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
128 code point U+1D11E, the musical G clef character, may be
129 expressed as U'1D11E'.
131 See the "Tokens" section in the PSPP manual for more information.
133 - In previous versions of PSPP, in a string expressed in
134 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
135 bytes in the locale encoding. In this version of PSPP, X'hh'
136 syntax always expresses bytes in UTF-8 encoding.
138 See the "Tokens" section in the PSPP manual for more information.
140 * PSPPIRE graphical user interface improvements:
142 - Added support for non-ASCII characters in strings, labels and
145 - A "Split Window" function is available, which makes it easier to
146 see different parts of a large data file.
148 - Data files can now be opened by specifing their name as the first
149 argument. This means that on a properly configured desktop, double
150 clicking on an icon will open the file.
152 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
153 via using an "intelligent" application assistant dialog.
157 - The new "cairo" output driver supports output in PostScript, PDF,
158 and SVG formats. Its functionality is a superset of that of the
159 "postscript" driver, which has been removed. You must have Cairo
160 and Pango installed to build the "cairo" driver.
162 - Charts are now produced with Cairo and Pango, instead of libplot.
163 Without them, the new graphing features will not work. If you do
164 not have Cairo and Pango installed, you must run `configure' with
167 - The plain text output driver now properly supports multibyte UTF-8
168 characters, including double-width characters and combining
171 - Output to OpenDocument format is now supported.
173 - The HTML output is much improved.
175 * The "pspp" program has a new option --batch (or -b) that selects
176 "batch" syntax mode. In previous versions of PSPP this syntax mode
177 was the default. Now a new "auto" syntax mode is the default. In
178 "auto" mode, PSPP interprets most syntax files correctly regardless
179 of their intended syntax mode.
181 See the "Syntax Variants" section in the PSPP manual for more
184 * The "pspp" program has a new option --syntax-encoding that
185 specifies the encoding for syntax files listed on the command line,
186 as well as the default encoding for syntax files included with
187 INCLUDE or INSERT. The default is to accept the system locale
188 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
189 one the system file uses.
191 See the documentation for the INSERT command in the PSPP manual for
194 * Text data files that PRINT and WRITE creates now use the system
195 native line ends by default (CRLF on Windows, LF only elsewhere).
196 Use the new ENDS subcommand on FILE HANDLE to override the default.
198 * A new Perl module allows Perl programs to read and write PSPP
201 * A tutorial chapter has been added to the user manual.
203 Changes from 0.6.1 to 0.6.2:
207 - Dutch, thanks to Harry Thijssen.
209 - Brazilian Portuguese, thanks to Michel Boaventura.
211 Thanks for translations are also due to the coordinators at
212 translationproject.org.
214 * Statistical bug fixes:
216 - REGRESSION: Report correct standard error of the estimate (bug
219 - T-TEST: Report correct significance of paired sample T-test in
220 the common case (bug #26936) and corner cases. Thanks to Mike
221 Griffiths and Matej Cepl for reporting these bugs.
223 * Build fixes and changes:
225 - Fix build with GTK+ 2.17.4 and later.
227 - Make running "make" after running "configure" with different
228 settings reliably rebuild version.c.
230 - Cygwin and MinGW build fixes.
232 - Fixes for building with recent gnulib.
234 - The Makefile now honors two new variables, PSPP_LDFLAGS and
235 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
236 binaries, respectively. This makes building easier for some
239 - Fixes for "configure --enable-relocatable" (bug #25508).
241 * Data file bug fixes and changes:
243 - Fix reading text data files that contain a mix of white space
244 and commas. Now "a ,b" is treated as two fields containing "a"
245 and "b"; previously it was treated as three, with an empty field
248 - Fix writing corrupted .sav files on Windows.
250 - Fix writing variable labels longer than 252 bytes to save files.
251 Thanks to Robert Westlund for reporting this bug.
253 - Fix writing corrupted .por files (bug #26034).
255 - Fix reading .por files whose initial lines are not padded out
256 with spaces as expected.
258 - PSPP will no longer issue warnings about some .sav file records
259 or values that it does not understand. These warnings were
260 harmless, but needlessly alarmed some users.
262 - Fix crash reading empty string fields from PostgreSQL databases.
264 * Bug fixes that affect PSPP and PSPPIRE:
266 - Users may now control precision of output statistics. Instead
267 of hard coding the width and decimals of output numbers, respect
268 the default format in most instances. Counts are now normally
269 displayed with the format of the weight variable, if any.
271 - Fix crash when an INSERT command specifies the name of a file
272 that does not exist (bug #24569).
274 - Fix crash when CROSSTABS specifies a long-string variable (bugs
277 - Fix crash drawing pie charts with many segments.
279 - Fix crash when NUMERIC specifies an invalid format.
281 * PSPPIRE bug fixes and changes:
283 - On Windows, write the output file to the user's home directory
284 instead of the current directory, to better match user
287 - Some data editor fixes.
291 - Fix typo in BINOMIAL section of user manual (bug #25892).
293 Changes from 0.6.0 to 0.6.1:
295 * Statistical bug fixes:
297 - Report correct standardized regression coefficients in linear
298 regression output (bug #23567).
300 * Bug fixes that affect PSPP and PSPPIRE:
302 - Avoid crash with pie charts (bug #24014).
304 - Don't append % to count totals (bug #24003).
306 - Don't crash on bad input (bug #24031).
308 - Don't crash if "end data." is not left aligned (bug #24115).
310 - Change default workspace value to 64 MB, to avoid unnecessary
311 disk accesses on modern machines.
315 - Add ".sav" or ".por" suffix to filename when saving with Save_As
318 - Make it possible to reopen the output window on Windows (bug
321 - A POSIX regular expression library is now included and used
322 automatically if the host does not have one or has one that is
325 * Build fixes and changes:
327 - Work around bug in GSL that prevented build with recent GCC
328 versions without manually adding -fgnu89-inline to CFLAGS.
330 - Also warn about missing prerequisites as we encounter them (bug
333 - Distribute necessary files to allow users working from the
334 distributed tarball to configure with --enable-gui-tools.
336 - Append $(EXEEXT_FOR_BUILD) to output file name when building
337 q2c, fixing build problems on Windows.
339 - GSL 1.8 or later is now required.
341 - Build errors with --enable-relocatable were fixed.
343 * The German translations were removed, since native German speakers
344 found them too poor to be useful.
346 Changes from 0.4.0 to 0.6.0:
348 * The PSPP license is now version 3 or later of the GNU General
349 Public License. Previously, it was version 2 or later.
351 * PSPP now has a graphical interface, called PSPPIRE. This
352 interface allows you to enter data and variable definitions
353 interactively. Commands may be executed in syntax form, or by
354 using the interactive dialog boxes available from the dropdown
357 * A few sample syntax files are now included in the `examples'
360 * Numerous major and minor bugs have been fixed.
364 * The INSTALL file now reflects the details of how to install
365 PSPP. It is a tailored version of the generic installation
366 instructions, instead of a verbatim copy.
368 * iconv, which is ordinarily installed as part of a Unix-like
369 system, is now required. If you don't have it already, you can
370 install GNU libiconv (http://www.gnu.org/software/libiconv/).
372 * libxml2 and zlib are new optional dependencies. They are
373 required to use PSPP's support for reading Gnumeric files.
375 Statistical procedure changes:
377 * REGRESSION is a new procedure for fitting linear models to data
378 via least-squares estimation.
380 * NPAR TESTS is a new procedure for non-parametric tests. In this
381 release, it supports binomial and chi-square tests.
383 * RANK is a new procedure to rank variables. It supports numerous
386 * FREQUENCIES can now output histograms and pie charts. These
387 features were present in earlier releases, but not documented.
389 User interface changes:
391 * In many situations where PSPP once terminated with a fatal
392 error, PSPP now recovers and continues execution.
394 * PSPP is now able to start up and run even if it cannot find its
397 * Journaling of interactive commands to a disk file is now
398 implemented. By default, journaling is enabled, to a file named
399 `pspp.jnl' in the current directory. SET JOURNAL may be used to
402 * The use of `+' between syntax file names on the command line to
403 prevent the dictionary from being cleared between their
404 executions is no longer supported. All syntax files are now
405 executed as if `+' had been specified.
407 * The -d/--define and -u/--undef command line options are no
408 longer supported. Instead, use /usr/bin/env or shell primitives
409 to define or clear environment variables before invoking PSPP.
411 * If a syntax file named named `rc' is found in a configuration
412 directory (such as $HOME/.pspp), it is executed before any
413 syntax file specified on the command line. The -r or
414 --no-statrc command line option may be used to disable this
419 * Output configuration options have changed. Please refer to the
420 manual for a full description of the available options.
422 In consequence, you will need to reinstall your "devices" file.
423 "make install" will do this for you.
425 * Most error messages are now written to PSPP output files by
426 default. SET ERROR can be used to disable this behavior.
428 * When invoked interactively, PSPP now by default produces output
429 on the terminal, piping it through the "more" program.
430 Previously, by default output was written only to file
431 pspp.list. On most terminals, the page length used for output
432 automatically adapts to the terminal size, even if the terminal
437 - This driver now supports charts in output. Charts are written
438 as separate files that the main output file refers to. By
439 default, charts are written in PNG format to files named
440 pspp-1.png, pspp-2.png, and so on.
442 - Configurations are provided that use VT100 (and xterm)
443 line-drawing characters in tables. The option "-o list-vt100"
444 requests use of this device for output to pspp.list.
448 - The default paper size is now determined using the PAPERSIZE
449 environment variable, or the LC_PAPER locale category on
450 systems that support it. If these are not set, the default is
451 now A4, instead of US letter. To make US letter the default,
452 set PAPERSIZE to "letter" in your environment.
454 - Font metrics are now read from AFM files, instead of
455 Groff-format metrics files. PostScript fonts can now be
458 In consequence, you will need to install an AFM file for each
459 font used in PostScript output. "make install" will install
460 AFM files for the standard PostScript fonts, including the
461 ones that the PostScript driver uses by default.
463 - Standard paper sizes no longer need to be specified through a
464 configuration file. The "papersize" configuration file is no
465 longer needed, or supported.
467 - The PostScript prologue is no longer obtained from the
468 "ps-prologue" configuration file. This configuration file is
469 no longer needed, or supported.
473 - The HTML prologue is no longer obtained from the
474 "html-prologue" configuration file. This configuration file
475 is no longer needed, or supported.
477 Command language changes:
479 * The following commands are new:
481 - GET DATA, which currently supports reading Gnumeric files and
482 text data files. It will be extended later to read other
483 types of foreign data.
485 - CD, to change the current directory.
487 - INSERT, to execute a syntax file.
489 - DELETE VARIABLES, to remove variables from the active file
492 - ADD DOCUMENT, to add text to active file documents.
494 - CLOSE FILE HANDLE (a PSPP extension; see below).
496 - XEXPORT, a PSPP extension that is a transformation equivalent
499 * The following functions for transformation expressions are new:
501 - DATEDIFF, for computing the difference of two dates.
503 - DATESUM, for advancing a date by a specified duration.
505 - VALUELABEL, to obtain the value label for a value.
507 * PSPP now supports very long string variables (over 255 bytes
510 * MATCH FILES now supports the FIRST and LAST subcommands.
512 * Previous versions of PSPP prohibited using commands to both read and
513 write a single file at the same time. Now, PSPP allows this, and
514 the new version of the file atomically replaces the old version.
516 * The following commands are no longer available. They will be
517 re-implemented in a later release:
519 - CLEAR TRANSFORMATIONS
525 * The PROCESS IF command, which was deprecated, has been removed.
526 You may replace any usage of it by SELECT IF following
527 TEMPORARY, which has the same effect.
529 * The output format for variables created by VECTOR may now be
530 specified as part of the VECTOR syntax.
532 "Scratch files", a new PSPP extension:
534 A scratch file, like a system file, consists of a dictionary and
535 any number of cases. Small scratch files are stored in memory;
536 one that grows too large is written to disk. By default, any file
537 handle whose name begins with # is assumed to refer to a scratch
540 Scratch files can be used just about anywhere a system or portable
541 file can be used. Also, portable files are now allowed in most
542 places that system files were allowed in previous PSPP version.
544 A new CLOSE FILE HANDLE command allows the storage associated with
545 scratch files to be freed. It also allows file handles to be
546 reassigned to new files.
548 For more information on scratch files, refer to the "File Handles"
549 section in the PSPP manual. For specifics of what commands now
550 allow what kinds of files to be specified, refer to the
551 documentation on those particular commands.
555 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
556 translation, are now supported. Use FILE HANDLE to specify the
557 format of these files.
559 * Little-endian, big-endian, and VAX-endian formats are now
560 supported for integer binary formats when reading and writing
561 data files. The new RIB and WIB subcommands on the SET command
562 control endianness of integer data. The default is the host's
565 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
566 floating point binary formats when reading and writing data
567 files. The new RRB and WRB subcommands on the SET command
568 control the floating point format. The default is the host's
569 native floating point format.
571 * DATA LIST now supports the SKIP subcommand, to skip records at
572 the beginning of a file. For compatibility, DATA LIST now
573 treats N format as F format for FREE and LIST format input.
575 * The SAVE and XSAVE commands now support the UNSELECTED,
576 PERMISSIONS, NAMES, and MAP subcommands.
578 * The EXPORT command has been re-implemented to obtain better
579 results. Support for the UNSELECTED, DIGITS, and TYPE
580 subcommands has been added.
582 * For compatibility, PRINT now inserts a space at the beginning of
583 every output line, even lines that would otherwise be blank,
584 when OUTFILE is specified. (The behavior of WRITE is
587 * For compatibility, PRINT EJECT now inserts the digit `1' at the
588 beginning of each line that should begin a new page.
590 * For compatibility, WRITE now outputs the system-missing value as
591 a field filled with spaces. Binary formats are an exception.
592 (The behavior of PRINT is unchanged.)
596 * Input and output format descriptions have been rewritten. They
597 now precisely describe what is accepted on input and written on
600 * The descriptions of the PSPP system and portable file formats
601 have been extensively revised and improved.
603 For developers, the build system now requires Autoconf 2.60 and
606 Changes from 0.3.0 to 0.4.0:
608 Changes in build dependencies:
610 * The GNU Scientific Library (libgsl), version 1.6 or later, is
613 * libplot from GNU plotutils is optional. Without it, the new
614 graphing features will not work. If you do not have it
615 installed, you must run `configure' with --without-libplot.
617 * libgmp2 is no longer a dependency.
619 Newly implemented commands and statistical features:
621 * EXAMINE, including its graphing features.
623 * FREQUENCIES now supports percentiles.
631 * SORT CASES now sorts stably, that is, two cases with equal sort
632 criteria will be in the same relative order before and after the
635 * T-TEST (re-written).
637 * DATE and USE. These commands are parsed but otherwise ignored,
638 to enhance compatibility with certain command files that invoke
641 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
642 currently have no effect on PSPP output, but their values are
643 written to and read from system files and thus may affect
644 third-party software.
646 * SET EPOCH implemented.
648 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
651 * FILE HANDLE now supports custom tab widths.
653 Long variable names (and other identifiers) are now supported. Up
654 to the first 64 bytes of each identifier is significant. PSPP now
655 reads and writes system files compatible with SPSS version 12.
657 New --algorithm and --syntax command line options allow
658 SPSS-compatible or enhanced modes to be selected.
660 Support for transformation expressions has been rewritten and
661 significantly improved. Refer to the manual for details.
663 Calculation of moments (mean, standard deviation, kurtosis,
664 skewness) has been rewritten and should now be more accurate. In
665 --algorithm=enhanced mode moments may be more accurate than SPSS in
668 Numerous bugs have been fixed, too many to mention here. Many new
669 tests have been added, leading to the discovery and fixing of many
672 The ASCII output driver can now squeeze multiple blank lines into
675 Much of the code has been rewritten and refactored. It is now much
678 The FILE TYPE and REPEATING DATA commands have been disabled for
679 this release because their implementations were deemed too buggy to
680 be useful. They will be fixed and replaced in a future release.
682 New pspp-mode for Emacs (in pspp-mode.el).
684 Added rudimentary command-line completion for interactive input.
686 lib/julcal and lib/dcdflib are no longer used, so they have been
689 For developers, the build system now requires Autoconf 2.58 and
690 Automake 1.7. The included gettext has been updated to version
693 Some reports state that Texinfo 4.8, the latest version, may be
694 necessary to successfully format the documentation on some systems.
696 Version 0.3.0 changes since 0.2.3:
700 * Using alphanumeric variables in functions under AGGREGATE
703 * Under certain circumstances, the final case would be omitted
704 from the results of an AGGREGATE operation. Fixed.
706 * Undefined behavior was invoked by referencing a freed pointer
707 under certain circumstances. Fixed.
709 * A wrong record size was displayed when paging the active file to
712 * Not having enough temporary space for sorting caused a core
715 * Syntax errors in function descriptions on AGGREGATE caused core
718 * A null pointer was dereferenced, causing a core dump, when
719 PERCENTILES was specified on FREQUENCIES. This fixes the
720 problem, but PSPP still doesn't calculate percentiles.
722 * SORT always sorted in ascending order. Fixed.
724 * Some minor memory leaks in the expression parser were removed.
726 * Many assertions fixed for strict ANSI C compliance.
730 * SET ECHO ON now implemented, but turned off by default.
732 * PRINT specifier supported on END REPEAT.
736 * System libgmp2 library is used if installed instead of
737 unconditionally using the included libgmp2 subset.
739 * Extensive code cleanup, which continues.
741 * Added CORRELATIONS command parser, but not implemented.
743 Version 0.2.3 changes since 0.2.2:
747 * SPLIT FILE with a string variable caused a core dump. Fixed.
749 * Nested INCLUDEs didn't work. Fixed.
751 * The MATCH FILES procedure set the values of variables not present
752 to 0. It should have been SYSMIS. This is now fixed.
754 * The REMARK command was too aggressive about skipping lines. It
755 didn't like being the last command in a file.
757 * Comment parsing wasn't consistent with the rest of the code in its
758 idea of where one command ends and another starts. This meant
759 that sometimes commands would be mysteriously ignored. Thanks to
760 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
762 * The TABLE subcommand on MATCH FILES worked only erratically at
763 best. This fixes it. Thanks to Dr. Dirk Melcher
764 <BZN-mdksh@t-online.de> for reporting this bug.
766 * VARIABLE LABELS rejected a slash before the first variable
767 specification, contradicting the documentation. Thanks to Walter
768 M. Gray <graywm@northernc.on.ca> for reporting this bug.
770 * Because of an incorrect optimization in memory allocation,
771 CROSSTABS sometimes segfaulted when asked to output multiple
772 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
775 * CROSSTABS didn't display value labels for column and row
776 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
779 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
780 <BZN-mdksh@t-online.de> for reporting this bug.
782 * The TABLE subcommand on MATCH FILES worked only erratically at
783 best. This fixes it. Thanks to Dr. Dirk Melcher
784 <BZN-mdksh@t-online.de> for reporting this bug.
786 * VARIABLE LABELS rejected a slash before the first variable
787 specification, contradicting the documentation. Thanks to Walter
788 M. Gray <graywm@northernc.on.ca> for reporting this bug.
790 * Because of an incorrect optimization in memory allocation,
791 CROSSTABS sometimes segfaulted when asked to output multiple
792 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
795 * CROSSTABS didn't display value labels for column and row
796 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
799 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
800 <BZN-mdksh@t-online.de> for reporting this bug.
802 * MATCH FILES corrupted memory and dumped core on some syntax
805 * MATCH FILES should set numeric values not available to the
806 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
