5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
9 * Formatting of SYSFILE INFO output was made easier to read.
11 Changes from 0.8.3 to 0.8.3.1:
13 * Fixed a bug where planned comparisons in oneway anova did not correctly
14 handle negative T-values.
16 Changes from 0.8.2 to 0.8.3:
18 * Independent T-Tests displayed the standard error of the difference
19 and the confidence interval for the unequal variances case, where
20 the equal variances case should have been. This has been fixed.
22 * REGRESSION now recognises /STATISTICS=CI(x) which causes confidence
23 intervals for the coefficients to be printed.
25 * When DESCRIPTIVES calculates Z scores, it now omits cases filtered
26 by the current FILTER settings.
28 * PSPPIRE graphical user interface improvements:
30 - Dialog boxes with source variable lists can now choose the sort
31 order; right click and select from the popup menu.
33 - File|Open now allows an encoding to be selected for opening
36 - File|Display Data File Information|External File... now allows an
37 encoding to be selected.
39 - A problem with the Means dialog has been resolved (bug #41433).
41 - Several problems related to the input of spreadsheets have been
42 fixed (bug #41657, #41620
44 * System file related improvements:
46 - With ENCODING="DETECT", SYSFILE INFO can now help the user to
47 pick an encoding for reading a system file that does not identify
50 - SYSFILE INFO now accepts an ENCODING subcommand to specify the
51 character encoding of string data in the system file.
53 - Variable labels over 255 bytes long are now accepted without
54 truncation (bug #41863).
56 - System files that contain duplicate variable names may now be
57 read successfully (bug #41475).
59 Changes from 0.8.1 to 0.8.2:
61 * Charts are now rendered with colours from the Tango palette instead
62 of fully saturated primaries.
64 * Support for new system file variants:
66 - PSPP can now read and write ZCOMPRESSED system files, which
67 compress data much more effectively than older "compressed"
68 files. (The older format is still supported.)
70 - PSPP can now decrypt encrypted system files, using the new
71 pspp-convert utility. The encrypted system file format is
72 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
73 do not directly read or write this format.
75 * Missing values for long string variables are now read from and
76 written to system files in an SPSS-compatible fashion.
78 (Earlier versions of PSPP that supported missing values for long
79 string variables wrote them to system files in an SPSS-incompatible
80 way. To fix the problem, read the system file with this version of
81 PSPP and then save a new copy of it.)
83 * pspp-convert, a new standalone utility for converting SPSS system
84 and portable files to other formats, is now included. The initial
85 version supports comma-separated value files as output format.
86 pspp-convert can also decrypt encrypted system files.
90 - zlib is now a required dependency. (Previously it was optional.)
92 Changes from 0.8.0 to 0.8.1:
98 * Changes to existing commands:
100 - CROSSTABS: The requirement that one expected count must be less than five
101 before Fishers Exact Test will be reported has been removed.
103 * PSPPIRE graphical user interface improvements:
105 - A new set of icons has been contributed.
107 - Syntax windows now parse syntax in "auto" mode, which in practice
108 should mean that both "batch" and "interactive" syntax now works,
109 instead of just "interactive" syntax.
111 - The variable pane of data windows now include a Role column.
115 - System files written by IBM SPSS 21 are now read without warnings.
117 - System files written by "VOXCO INTERVIEWER 4.3" are now read
120 - PSPPIRE should now more gracefully handle syntax files that contain
123 Changes from 0.6.2 to 0.8.0:
129 - DATAFILE ATTRIBUTES
136 - LOGISTIC REGRESSION
140 - PRESERVE and RESTORE
144 - SAVE TRANSLATE to CSV and tab-delimited files
146 - VARIABLE ATTRIBUTES
148 * Changes to existing commands:
150 - AUTORECODE has a new GROUP subcommand.
152 - CROSSTABS has been re-implemented to fix numerous bugs.
154 - EXAMINE: /MISSING=LISTWISE is now the default.
156 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
157 contains an INCLUDE or INSERT command, substitutions are not
158 applied to the included file.
160 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
162 - HOST has been updated to use more modern syntax.
164 - Most commands that work with data files now support a new
167 - MISSING VALUES can now assign missing values to long string
170 - ONEWAY: the POSTHOC subcommand is now implemented.
172 - The following new subcommands to NPAR TESTS have been implemented:
173 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
174 MCNEMAR, SIGN, WILCOXON, and RUNS
176 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
177 DPROMPT subcommands. The defaults are now fixed values.
179 - SHOW now has a JOURNAL subcommand, to show the location of the
182 - VALUE LABELS can now assign value labels to long string
185 * Other language changes:
187 - The new DATASET commands replace the "scratch file" PSPP
188 extension, which is no longer supported.
190 - Strings may now include arbitrary Unicode code points specified
191 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
192 code point U+1D11E, the musical G clef character, may be
193 expressed as U'1D11E'.
195 See the "Tokens" section in the PSPP manual for more information.
197 - In previous versions of PSPP, in a string expressed in
198 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
199 bytes in the locale encoding. In this version of PSPP, X'hh'
200 syntax always expresses bytes in UTF-8 encoding.
202 See the "Tokens" section in the PSPP manual for more information.
204 * PSPPIRE graphical user interface improvements:
206 - Added support for non-ASCII characters in strings, labels and
209 - A "Split Window" function is available, which makes it easier to
210 see different parts of a large data file.
212 - Data files can now be opened by specifing their name as the first
213 argument. This means that on a properly configured desktop, double
214 clicking on an icon will open the file.
216 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
217 via using an "intelligent" application assistant dialog.
221 - The new "cairo" output driver supports output in PostScript, PDF,
222 and SVG formats. Its functionality is a superset of that of the
223 "postscript" driver, which has been removed. You must have Cairo
224 and Pango installed to build the "cairo" driver.
226 - Charts are now produced with Cairo and Pango, instead of libplot.
227 Without them, the new graphing features will not work. If you do
228 not have Cairo and Pango installed, you must run `configure' with
231 - The plain text output driver now properly supports multibyte UTF-8
232 characters, including double-width characters and combining
235 - Output to OpenDocument format is now supported.
237 - The HTML output is much improved.
239 * The "pspp" program has a new option --batch (or -b) that selects
240 "batch" syntax mode. In previous versions of PSPP this syntax mode
241 was the default. Now a new "auto" syntax mode is the default. In
242 "auto" mode, PSPP interprets most syntax files correctly regardless
243 of their intended syntax mode.
245 See the "Syntax Variants" section in the PSPP manual for more
248 * The "pspp" program has a new option --syntax-encoding that
249 specifies the encoding for syntax files listed on the command line,
250 as well as the default encoding for syntax files included with
251 INCLUDE or INSERT. The default is to accept the system locale
252 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
253 one the system file uses.
255 See the documentation for the INSERT command in the PSPP manual for
258 * Text data files that PRINT and WRITE creates now use the system
259 native line ends by default (CRLF on Windows, LF only elsewhere).
260 Use the new ENDS subcommand on FILE HANDLE to override the default.
262 * A new Perl module allows Perl programs to read and write PSPP
265 * A tutorial chapter has been added to the user manual.
267 Changes from 0.6.1 to 0.6.2:
271 - Dutch, thanks to Harry Thijssen.
273 - Brazilian Portuguese, thanks to Michel Boaventura.
275 Thanks for translations are also due to the coordinators at
276 translationproject.org.
278 * Statistical bug fixes:
280 - REGRESSION: Report correct standard error of the estimate (bug
283 - T-TEST: Report correct significance of paired sample T-test in
284 the common case (bug #26936) and corner cases. Thanks to Mike
285 Griffiths and Matej Cepl for reporting these bugs.
287 * Build fixes and changes:
289 - Fix build with GTK+ 2.17.4 and later.
291 - Make running "make" after running "configure" with different
292 settings reliably rebuild version.c.
294 - Cygwin and MinGW build fixes.
296 - Fixes for building with recent gnulib.
298 - The Makefile now honors two new variables, PSPP_LDFLAGS and
299 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
300 binaries, respectively. This makes building easier for some
303 - Fixes for "configure --enable-relocatable" (bug #25508).
305 * Data file bug fixes and changes:
307 - Fix reading text data files that contain a mix of white space
308 and commas. Now "a ,b" is treated as two fields containing "a"
309 and "b"; previously it was treated as three, with an empty field
312 - Fix writing corrupted .sav files on Windows.
314 - Fix writing variable labels longer than 252 bytes to save files.
315 Thanks to Robert Westlund for reporting this bug.
317 - Fix writing corrupted .por files (bug #26034).
319 - Fix reading .por files whose initial lines are not padded out
320 with spaces as expected.
322 - PSPP will no longer issue warnings about some .sav file records
323 or values that it does not understand. These warnings were
324 harmless, but needlessly alarmed some users.
326 - Fix crash reading empty string fields from PostgreSQL databases.
328 * Bug fixes that affect PSPP and PSPPIRE:
330 - Users may now control precision of output statistics. Instead
331 of hard coding the width and decimals of output numbers, respect
332 the default format in most instances. Counts are now normally
333 displayed with the format of the weight variable, if any.
335 - Fix crash when an INSERT command specifies the name of a file
336 that does not exist (bug #24569).
338 - Fix crash when CROSSTABS specifies a long-string variable (bugs
341 - Fix crash drawing pie charts with many segments.
343 - Fix crash when NUMERIC specifies an invalid format.
345 * PSPPIRE bug fixes and changes:
347 - On Windows, write the output file to the user's home directory
348 instead of the current directory, to better match user
351 - Some data editor fixes.
355 - Fix typo in BINOMIAL section of user manual (bug #25892).
357 Changes from 0.6.0 to 0.6.1:
359 * Statistical bug fixes:
361 - Report correct standardized regression coefficients in linear
362 regression output (bug #23567).
364 * Bug fixes that affect PSPP and PSPPIRE:
366 - Avoid crash with pie charts (bug #24014).
368 - Don't append % to count totals (bug #24003).
370 - Don't crash on bad input (bug #24031).
372 - Don't crash if "end data." is not left aligned (bug #24115).
374 - Change default workspace value to 64 MB, to avoid unnecessary
375 disk accesses on modern machines.
379 - Add ".sav" or ".por" suffix to filename when saving with Save_As
382 - Make it possible to reopen the output window on Windows (bug
385 - A POSIX regular expression library is now included and used
386 automatically if the host does not have one or has one that is
389 * Build fixes and changes:
391 - Work around bug in GSL that prevented build with recent GCC
392 versions without manually adding -fgnu89-inline to CFLAGS.
394 - Also warn about missing prerequisites as we encounter them (bug
397 - Distribute necessary files to allow users working from the
398 distributed tarball to configure with --enable-gui-tools.
400 - Append $(EXEEXT_FOR_BUILD) to output file name when building
401 q2c, fixing build problems on Windows.
403 - GSL 1.8 or later is now required.
405 - Build errors with --enable-relocatable were fixed.
407 * The German translations were removed, since native German speakers
408 found them too poor to be useful.
410 Changes from 0.4.0 to 0.6.0:
412 * The PSPP license is now version 3 or later of the GNU General
413 Public License. Previously, it was version 2 or later.
415 * PSPP now has a graphical interface, called PSPPIRE. This
416 interface allows you to enter data and variable definitions
417 interactively. Commands may be executed in syntax form, or by
418 using the interactive dialog boxes available from the dropdown
421 * A few sample syntax files are now included in the `examples'
424 * Numerous major and minor bugs have been fixed.
428 * The INSTALL file now reflects the details of how to install
429 PSPP. It is a tailored version of the generic installation
430 instructions, instead of a verbatim copy.
432 * iconv, which is ordinarily installed as part of a Unix-like
433 system, is now required. If you don't have it already, you can
434 install GNU libiconv (http://www.gnu.org/software/libiconv/).
436 * libxml2 and zlib are new optional dependencies. They are
437 required to use PSPP's support for reading Gnumeric files.
439 Statistical procedure changes:
441 * REGRESSION is a new procedure for fitting linear models to data
442 via least-squares estimation.
444 * NPAR TESTS is a new procedure for non-parametric tests. In this
445 release, it supports binomial and chi-square tests.
447 * RANK is a new procedure to rank variables. It supports numerous
450 * FREQUENCIES can now output histograms and pie charts. These
451 features were present in earlier releases, but not documented.
453 User interface changes:
455 * In many situations where PSPP once terminated with a fatal
456 error, PSPP now recovers and continues execution.
458 * PSPP is now able to start up and run even if it cannot find its
461 * Journaling of interactive commands to a disk file is now
462 implemented. By default, journaling is enabled, to a file named
463 `pspp.jnl' in the current directory. SET JOURNAL may be used to
466 * The use of `+' between syntax file names on the command line to
467 prevent the dictionary from being cleared between their
468 executions is no longer supported. All syntax files are now
469 executed as if `+' had been specified.
471 * The -d/--define and -u/--undef command line options are no
472 longer supported. Instead, use /usr/bin/env or shell primitives
473 to define or clear environment variables before invoking PSPP.
475 * If a syntax file named named `rc' is found in a configuration
476 directory (such as $HOME/.pspp), it is executed before any
477 syntax file specified on the command line. The -r or
478 --no-statrc command line option may be used to disable this
483 * Output configuration options have changed. Please refer to the
484 manual for a full description of the available options.
486 In consequence, you will need to reinstall your "devices" file.
487 "make install" will do this for you.
489 * Most error messages are now written to PSPP output files by
490 default. SET ERROR can be used to disable this behavior.
492 * When invoked interactively, PSPP now by default produces output
493 on the terminal, piping it through the "more" program.
494 Previously, by default output was written only to file
495 pspp.list. On most terminals, the page length used for output
496 automatically adapts to the terminal size, even if the terminal
501 - This driver now supports charts in output. Charts are written
502 as separate files that the main output file refers to. By
503 default, charts are written in PNG format to files named
504 pspp-1.png, pspp-2.png, and so on.
506 - Configurations are provided that use VT100 (and xterm)
507 line-drawing characters in tables. The option "-o list-vt100"
508 requests use of this device for output to pspp.list.
512 - The default paper size is now determined using the PAPERSIZE
513 environment variable, or the LC_PAPER locale category on
514 systems that support it. If these are not set, the default is
515 now A4, instead of US letter. To make US letter the default,
516 set PAPERSIZE to "letter" in your environment.
518 - Font metrics are now read from AFM files, instead of
519 Groff-format metrics files. PostScript fonts can now be
522 In consequence, you will need to install an AFM file for each
523 font used in PostScript output. "make install" will install
524 AFM files for the standard PostScript fonts, including the
525 ones that the PostScript driver uses by default.
527 - Standard paper sizes no longer need to be specified through a
528 configuration file. The "papersize" configuration file is no
529 longer needed, or supported.
531 - The PostScript prologue is no longer obtained from the
532 "ps-prologue" configuration file. This configuration file is
533 no longer needed, or supported.
537 - The HTML prologue is no longer obtained from the
538 "html-prologue" configuration file. This configuration file
539 is no longer needed, or supported.
541 Command language changes:
543 * The following commands are new:
545 - GET DATA, which currently supports reading Gnumeric files and
546 text data files. It will be extended later to read other
547 types of foreign data.
549 - CD, to change the current directory.
551 - INSERT, to execute a syntax file.
553 - DELETE VARIABLES, to remove variables from the active file
556 - ADD DOCUMENT, to add text to active file documents.
558 - CLOSE FILE HANDLE (a PSPP extension; see below).
560 - XEXPORT, a PSPP extension that is a transformation equivalent
563 * The following functions for transformation expressions are new:
565 - DATEDIFF, for computing the difference of two dates.
567 - DATESUM, for advancing a date by a specified duration.
569 - VALUELABEL, to obtain the value label for a value.
571 * PSPP now supports very long string variables (over 255 bytes
574 * MATCH FILES now supports the FIRST and LAST subcommands.
576 * Previous versions of PSPP prohibited using commands to both read and
577 write a single file at the same time. Now, PSPP allows this, and
578 the new version of the file atomically replaces the old version.
580 * The following commands are no longer available. They will be
581 re-implemented in a later release:
583 - CLEAR TRANSFORMATIONS
589 * The PROCESS IF command, which was deprecated, has been removed.
590 You may replace any usage of it by SELECT IF following
591 TEMPORARY, which has the same effect.
593 * The output format for variables created by VECTOR may now be
594 specified as part of the VECTOR syntax.
596 "Scratch files", a new PSPP extension:
598 A scratch file, like a system file, consists of a dictionary and
599 any number of cases. Small scratch files are stored in memory;
600 one that grows too large is written to disk. By default, any file
601 handle whose name begins with # is assumed to refer to a scratch
604 Scratch files can be used just about anywhere a system or portable
605 file can be used. Also, portable files are now allowed in most
606 places that system files were allowed in previous PSPP version.
608 A new CLOSE FILE HANDLE command allows the storage associated with
609 scratch files to be freed. It also allows file handles to be
610 reassigned to new files.
612 For more information on scratch files, refer to the "File Handles"
613 section in the PSPP manual. For specifics of what commands now
614 allow what kinds of files to be specified, refer to the
615 documentation on those particular commands.
619 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
620 translation, are now supported. Use FILE HANDLE to specify the
621 format of these files.
623 * Little-endian, big-endian, and VAX-endian formats are now
624 supported for integer binary formats when reading and writing
625 data files. The new RIB and WIB subcommands on the SET command
626 control endianness of integer data. The default is the host's
629 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
630 floating point binary formats when reading and writing data
631 files. The new RRB and WRB subcommands on the SET command
632 control the floating point format. The default is the host's
633 native floating point format.
635 * DATA LIST now supports the SKIP subcommand, to skip records at
636 the beginning of a file. For compatibility, DATA LIST now
637 treats N format as F format for FREE and LIST format input.
639 * The SAVE and XSAVE commands now support the UNSELECTED,
640 PERMISSIONS, NAMES, and MAP subcommands.
642 * The EXPORT command has been re-implemented to obtain better
643 results. Support for the UNSELECTED, DIGITS, and TYPE
644 subcommands has been added.
646 * For compatibility, PRINT now inserts a space at the beginning of
647 every output line, even lines that would otherwise be blank,
648 when OUTFILE is specified. (The behavior of WRITE is
651 * For compatibility, PRINT EJECT now inserts the digit `1' at the
652 beginning of each line that should begin a new page.
654 * For compatibility, WRITE now outputs the system-missing value as
655 a field filled with spaces. Binary formats are an exception.
656 (The behavior of PRINT is unchanged.)
660 * Input and output format descriptions have been rewritten. They
661 now precisely describe what is accepted on input and written on
664 * The descriptions of the PSPP system and portable file formats
665 have been extensively revised and improved.
667 For developers, the build system now requires Autoconf 2.60 and
670 Changes from 0.3.0 to 0.4.0:
672 Changes in build dependencies:
674 * The GNU Scientific Library (libgsl), version 1.6 or later, is
677 * libplot from GNU plotutils is optional. Without it, the new
678 graphing features will not work. If you do not have it
679 installed, you must run `configure' with --without-libplot.
681 * libgmp2 is no longer a dependency.
683 Newly implemented commands and statistical features:
685 * EXAMINE, including its graphing features.
687 * FREQUENCIES now supports percentiles.
695 * SORT CASES now sorts stably, that is, two cases with equal sort
696 criteria will be in the same relative order before and after the
699 * T-TEST (re-written).
701 * DATE and USE. These commands are parsed but otherwise ignored,
702 to enhance compatibility with certain command files that invoke
705 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
706 currently have no effect on PSPP output, but their values are
707 written to and read from system files and thus may affect
708 third-party software.
710 * SET EPOCH implemented.
712 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
715 * FILE HANDLE now supports custom tab widths.
717 Long variable names (and other identifiers) are now supported. Up
718 to the first 64 bytes of each identifier is significant. PSPP now
719 reads and writes system files compatible with SPSS version 12.
721 New --algorithm and --syntax command line options allow
722 SPSS-compatible or enhanced modes to be selected.
724 Support for transformation expressions has been rewritten and
725 significantly improved. Refer to the manual for details.
727 Calculation of moments (mean, standard deviation, kurtosis,
728 skewness) has been rewritten and should now be more accurate. In
729 --algorithm=enhanced mode moments may be more accurate than SPSS in
732 Numerous bugs have been fixed, too many to mention here. Many new
733 tests have been added, leading to the discovery and fixing of many
736 The ASCII output driver can now squeeze multiple blank lines into
739 Much of the code has been rewritten and refactored. It is now much
742 The FILE TYPE and REPEATING DATA commands have been disabled for
743 this release because their implementations were deemed too buggy to
744 be useful. They will be fixed and replaced in a future release.
746 New pspp-mode for Emacs (in pspp-mode.el).
748 Added rudimentary command-line completion for interactive input.
750 lib/julcal and lib/dcdflib are no longer used, so they have been
753 For developers, the build system now requires Autoconf 2.58 and
754 Automake 1.7. The included gettext has been updated to version
757 Some reports state that Texinfo 4.8, the latest version, may be
758 necessary to successfully format the documentation on some systems.
760 Version 0.3.0 changes since 0.2.3:
764 * Using alphanumeric variables in functions under AGGREGATE
767 * Under certain circumstances, the final case would be omitted
768 from the results of an AGGREGATE operation. Fixed.
770 * Undefined behavior was invoked by referencing a freed pointer
771 under certain circumstances. Fixed.
773 * A wrong record size was displayed when paging the active file to
776 * Not having enough temporary space for sorting caused a core
779 * Syntax errors in function descriptions on AGGREGATE caused core
782 * A null pointer was dereferenced, causing a core dump, when
783 PERCENTILES was specified on FREQUENCIES. This fixes the
784 problem, but PSPP still doesn't calculate percentiles.
786 * SORT always sorted in ascending order. Fixed.
788 * Some minor memory leaks in the expression parser were removed.
790 * Many assertions fixed for strict ANSI C compliance.
794 * SET ECHO ON now implemented, but turned off by default.
796 * PRINT specifier supported on END REPEAT.
800 * System libgmp2 library is used if installed instead of
801 unconditionally using the included libgmp2 subset.
803 * Extensive code cleanup, which continues.
805 * Added CORRELATIONS command parser, but not implemented.
807 Version 0.2.3 changes since 0.2.2:
811 * SPLIT FILE with a string variable caused a core dump. Fixed.
813 * Nested INCLUDEs didn't work. Fixed.
815 * The MATCH FILES procedure set the values of variables not present
