5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
7 Changes from 0.8.2 to 0.8.3:
9 * REGRESSION now recognises /STATISTICS=CI(x) which causes confidence
10 intervals for the coefficients to be printed.
12 Changes from 0.8.1 to 0.8.2:
14 * Charts are now rendered with colours from the Tango palette instead
15 of fully saturated primaries.
17 * Support for new system file variants:
19 - PSPP can now read and write ZCOMPRESSED system files, which
20 compress data much more effectively than older "compressed"
21 files. (The older format is still supported.)
23 - PSPP can now decrypt encrypted system files, using the new
24 pspp-convert utility. The encrypted system file format is
25 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
26 do not directly read or write this format.
28 * Missing values for long string variables are now read from and
29 written to system files in an SPSS-compatible fashion.
31 (Earlier versions of PSPP that supported missing values for long
32 string variables wrote them to system files in an SPSS-incompatible
33 way. To fix the problem, read the system file with this version of
34 PSPP and then save a new copy of it.)
36 * pspp-convert, a new standalone utility for converting SPSS system
37 and portable files to other formats, is now included. The initial
38 version supports comma-separated value files as output format.
39 pspp-convert can also decrypt encrypted system files.
43 - zlib is now a required dependency. (Previously it was optional.)
45 Changes from 0.8.0 to 0.8.1:
51 * Changes to existing commands:
53 - CROSSTABS: The requirement that one expected count must be less than five
54 before Fishers Exact Test will be reported has been removed.
56 * PSPPIRE graphical user interface improvements:
58 - A new set of icons has been contributed.
60 - Syntax windows now parse syntax in "auto" mode, which in practice
61 should mean that both "batch" and "interactive" syntax now works,
62 instead of just "interactive" syntax.
64 - The variable pane of data windows now include a Role column.
68 - System files written by IBM SPSS 21 are now read without warnings.
70 - System files written by "VOXCO INTERVIEWER 4.3" are now read
73 - PSPPIRE should now more gracefully handle syntax files that contain
76 Changes from 0.6.2 to 0.8.0:
93 - PRESERVE and RESTORE
97 - SAVE TRANSLATE to CSV and tab-delimited files
101 * Changes to existing commands:
103 - AUTORECODE has a new GROUP subcommand.
105 - CROSSTABS has been re-implemented to fix numerous bugs.
107 - EXAMINE: /MISSING=LISTWISE is now the default.
109 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
110 contains an INCLUDE or INSERT command, substitutions are not
111 applied to the included file.
113 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
115 - HOST has been updated to use more modern syntax.
117 - Most commands that work with data files now support a new
120 - MISSING VALUES can now assign missing values to long string
123 - ONEWAY: the POSTHOC subcommand is now implemented.
125 - The following new subcommands to NPAR TESTS have been implemented:
126 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
127 MCNEMAR, SIGN, WILCOXON, and RUNS
129 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
130 DPROMPT subcommands. The defaults are now fixed values.
132 - SHOW now has a JOURNAL subcommand, to show the location of the
135 - VALUE LABELS can now assign value labels to long string
138 * Other language changes:
140 - The new DATASET commands replace the "scratch file" PSPP
141 extension, which is no longer supported.
143 - Strings may now include arbitrary Unicode code points specified
144 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
145 code point U+1D11E, the musical G clef character, may be
146 expressed as U'1D11E'.
148 See the "Tokens" section in the PSPP manual for more information.
150 - In previous versions of PSPP, in a string expressed in
151 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
152 bytes in the locale encoding. In this version of PSPP, X'hh'
153 syntax always expresses bytes in UTF-8 encoding.
155 See the "Tokens" section in the PSPP manual for more information.
157 * PSPPIRE graphical user interface improvements:
159 - Added support for non-ASCII characters in strings, labels and
162 - A "Split Window" function is available, which makes it easier to
163 see different parts of a large data file.
165 - Data files can now be opened by specifing their name as the first
166 argument. This means that on a properly configured desktop, double
167 clicking on an icon will open the file.
169 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
170 via using an "intelligent" application assistant dialog.
174 - The new "cairo" output driver supports output in PostScript, PDF,
175 and SVG formats. Its functionality is a superset of that of the
176 "postscript" driver, which has been removed. You must have Cairo
177 and Pango installed to build the "cairo" driver.
179 - Charts are now produced with Cairo and Pango, instead of libplot.
180 Without them, the new graphing features will not work. If you do
181 not have Cairo and Pango installed, you must run `configure' with
184 - The plain text output driver now properly supports multibyte UTF-8
185 characters, including double-width characters and combining
188 - Output to OpenDocument format is now supported.
190 - The HTML output is much improved.
192 * The "pspp" program has a new option --batch (or -b) that selects
193 "batch" syntax mode. In previous versions of PSPP this syntax mode
194 was the default. Now a new "auto" syntax mode is the default. In
195 "auto" mode, PSPP interprets most syntax files correctly regardless
196 of their intended syntax mode.
198 See the "Syntax Variants" section in the PSPP manual for more
201 * The "pspp" program has a new option --syntax-encoding that
202 specifies the encoding for syntax files listed on the command line,
203 as well as the default encoding for syntax files included with
204 INCLUDE or INSERT. The default is to accept the system locale
205 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
206 one the system file uses.
208 See the documentation for the INSERT command in the PSPP manual for
211 * Text data files that PRINT and WRITE creates now use the system
212 native line ends by default (CRLF on Windows, LF only elsewhere).
213 Use the new ENDS subcommand on FILE HANDLE to override the default.
215 * A new Perl module allows Perl programs to read and write PSPP
218 * A tutorial chapter has been added to the user manual.
220 Changes from 0.6.1 to 0.6.2:
224 - Dutch, thanks to Harry Thijssen.
226 - Brazilian Portuguese, thanks to Michel Boaventura.
228 Thanks for translations are also due to the coordinators at
229 translationproject.org.
231 * Statistical bug fixes:
233 - REGRESSION: Report correct standard error of the estimate (bug
236 - T-TEST: Report correct significance of paired sample T-test in
237 the common case (bug #26936) and corner cases. Thanks to Mike
238 Griffiths and Matej Cepl for reporting these bugs.
240 * Build fixes and changes:
242 - Fix build with GTK+ 2.17.4 and later.
244 - Make running "make" after running "configure" with different
245 settings reliably rebuild version.c.
247 - Cygwin and MinGW build fixes.
249 - Fixes for building with recent gnulib.
251 - The Makefile now honors two new variables, PSPP_LDFLAGS and
252 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
253 binaries, respectively. This makes building easier for some
256 - Fixes for "configure --enable-relocatable" (bug #25508).
258 * Data file bug fixes and changes:
260 - Fix reading text data files that contain a mix of white space
261 and commas. Now "a ,b" is treated as two fields containing "a"
262 and "b"; previously it was treated as three, with an empty field
265 - Fix writing corrupted .sav files on Windows.
267 - Fix writing variable labels longer than 252 bytes to save files.
268 Thanks to Robert Westlund for reporting this bug.
270 - Fix writing corrupted .por files (bug #26034).
272 - Fix reading .por files whose initial lines are not padded out
273 with spaces as expected.
275 - PSPP will no longer issue warnings about some .sav file records
276 or values that it does not understand. These warnings were
277 harmless, but needlessly alarmed some users.
279 - Fix crash reading empty string fields from PostgreSQL databases.
281 * Bug fixes that affect PSPP and PSPPIRE:
283 - Users may now control precision of output statistics. Instead
284 of hard coding the width and decimals of output numbers, respect
285 the default format in most instances. Counts are now normally
286 displayed with the format of the weight variable, if any.
288 - Fix crash when an INSERT command specifies the name of a file
289 that does not exist (bug #24569).
291 - Fix crash when CROSSTABS specifies a long-string variable (bugs
294 - Fix crash drawing pie charts with many segments.
296 - Fix crash when NUMERIC specifies an invalid format.
298 * PSPPIRE bug fixes and changes:
300 - On Windows, write the output file to the user's home directory
301 instead of the current directory, to better match user
304 - Some data editor fixes.
308 - Fix typo in BINOMIAL section of user manual (bug #25892).
310 Changes from 0.6.0 to 0.6.1:
312 * Statistical bug fixes:
314 - Report correct standardized regression coefficients in linear
315 regression output (bug #23567).
317 * Bug fixes that affect PSPP and PSPPIRE:
319 - Avoid crash with pie charts (bug #24014).
321 - Don't append % to count totals (bug #24003).
323 - Don't crash on bad input (bug #24031).
325 - Don't crash if "end data." is not left aligned (bug #24115).
327 - Change default workspace value to 64 MB, to avoid unnecessary
328 disk accesses on modern machines.
332 - Add ".sav" or ".por" suffix to filename when saving with Save_As
335 - Make it possible to reopen the output window on Windows (bug
338 - A POSIX regular expression library is now included and used
339 automatically if the host does not have one or has one that is
342 * Build fixes and changes:
344 - Work around bug in GSL that prevented build with recent GCC
345 versions without manually adding -fgnu89-inline to CFLAGS.
347 - Also warn about missing prerequisites as we encounter them (bug
350 - Distribute necessary files to allow users working from the
351 distributed tarball to configure with --enable-gui-tools.
353 - Append $(EXEEXT_FOR_BUILD) to output file name when building
354 q2c, fixing build problems on Windows.
356 - GSL 1.8 or later is now required.
358 - Build errors with --enable-relocatable were fixed.
360 * The German translations were removed, since native German speakers
361 found them too poor to be useful.
363 Changes from 0.4.0 to 0.6.0:
365 * The PSPP license is now version 3 or later of the GNU General
366 Public License. Previously, it was version 2 or later.
368 * PSPP now has a graphical interface, called PSPPIRE. This
369 interface allows you to enter data and variable definitions
370 interactively. Commands may be executed in syntax form, or by
371 using the interactive dialog boxes available from the dropdown
374 * A few sample syntax files are now included in the `examples'
377 * Numerous major and minor bugs have been fixed.
381 * The INSTALL file now reflects the details of how to install
382 PSPP. It is a tailored version of the generic installation
383 instructions, instead of a verbatim copy.
385 * iconv, which is ordinarily installed as part of a Unix-like
386 system, is now required. If you don't have it already, you can
387 install GNU libiconv (http://www.gnu.org/software/libiconv/).
389 * libxml2 and zlib are new optional dependencies. They are
390 required to use PSPP's support for reading Gnumeric files.
392 Statistical procedure changes:
394 * REGRESSION is a new procedure for fitting linear models to data
395 via least-squares estimation.
397 * NPAR TESTS is a new procedure for non-parametric tests. In this
398 release, it supports binomial and chi-square tests.
400 * RANK is a new procedure to rank variables. It supports numerous
403 * FREQUENCIES can now output histograms and pie charts. These
404 features were present in earlier releases, but not documented.
406 User interface changes:
408 * In many situations where PSPP once terminated with a fatal
409 error, PSPP now recovers and continues execution.
411 * PSPP is now able to start up and run even if it cannot find its
414 * Journaling of interactive commands to a disk file is now
415 implemented. By default, journaling is enabled, to a file named
416 `pspp.jnl' in the current directory. SET JOURNAL may be used to
419 * The use of `+' between syntax file names on the command line to
420 prevent the dictionary from being cleared between their
421 executions is no longer supported. All syntax files are now
422 executed as if `+' had been specified.
424 * The -d/--define and -u/--undef command line options are no
425 longer supported. Instead, use /usr/bin/env or shell primitives
426 to define or clear environment variables before invoking PSPP.
428 * If a syntax file named named `rc' is found in a configuration
429 directory (such as $HOME/.pspp), it is executed before any
430 syntax file specified on the command line. The -r or
431 --no-statrc command line option may be used to disable this
436 * Output configuration options have changed. Please refer to the
437 manual for a full description of the available options.
439 In consequence, you will need to reinstall your "devices" file.
440 "make install" will do this for you.
442 * Most error messages are now written to PSPP output files by
443 default. SET ERROR can be used to disable this behavior.
445 * When invoked interactively, PSPP now by default produces output
446 on the terminal, piping it through the "more" program.
447 Previously, by default output was written only to file
448 pspp.list. On most terminals, the page length used for output
449 automatically adapts to the terminal size, even if the terminal
454 - This driver now supports charts in output. Charts are written
455 as separate files that the main output file refers to. By
456 default, charts are written in PNG format to files named
457 pspp-1.png, pspp-2.png, and so on.
459 - Configurations are provided that use VT100 (and xterm)
460 line-drawing characters in tables. The option "-o list-vt100"
461 requests use of this device for output to pspp.list.
465 - The default paper size is now determined using the PAPERSIZE
466 environment variable, or the LC_PAPER locale category on
467 systems that support it. If these are not set, the default is
468 now A4, instead of US letter. To make US letter the default,
469 set PAPERSIZE to "letter" in your environment.
471 - Font metrics are now read from AFM files, instead of
472 Groff-format metrics files. PostScript fonts can now be
475 In consequence, you will need to install an AFM file for each
476 font used in PostScript output. "make install" will install
477 AFM files for the standard PostScript fonts, including the
478 ones that the PostScript driver uses by default.
480 - Standard paper sizes no longer need to be specified through a
481 configuration file. The "papersize" configuration file is no
482 longer needed, or supported.
484 - The PostScript prologue is no longer obtained from the
485 "ps-prologue" configuration file. This configuration file is
486 no longer needed, or supported.
490 - The HTML prologue is no longer obtained from the
491 "html-prologue" configuration file. This configuration file
492 is no longer needed, or supported.
494 Command language changes:
496 * The following commands are new:
498 - GET DATA, which currently supports reading Gnumeric files and
499 text data files. It will be extended later to read other
500 types of foreign data.
502 - CD, to change the current directory.
504 - INSERT, to execute a syntax file.
506 - DELETE VARIABLES, to remove variables from the active file
509 - ADD DOCUMENT, to add text to active file documents.
511 - CLOSE FILE HANDLE (a PSPP extension; see below).
513 - XEXPORT, a PSPP extension that is a transformation equivalent
516 * The following functions for transformation expressions are new:
518 - DATEDIFF, for computing the difference of two dates.
520 - DATESUM, for advancing a date by a specified duration.
522 - VALUELABEL, to obtain the value label for a value.
524 * PSPP now supports very long string variables (over 255 bytes
527 * MATCH FILES now supports the FIRST and LAST subcommands.
529 * Previous versions of PSPP prohibited using commands to both read and
530 write a single file at the same time. Now, PSPP allows this, and
531 the new version of the file atomically replaces the old version.
533 * The following commands are no longer available. They will be
534 re-implemented in a later release:
536 - CLEAR TRANSFORMATIONS
542 * The PROCESS IF command, which was deprecated, has been removed.
543 You may replace any usage of it by SELECT IF following
544 TEMPORARY, which has the same effect.
546 * The output format for variables created by VECTOR may now be
547 specified as part of the VECTOR syntax.
549 "Scratch files", a new PSPP extension:
551 A scratch file, like a system file, consists of a dictionary and
552 any number of cases. Small scratch files are stored in memory;
553 one that grows too large is written to disk. By default, any file
554 handle whose name begins with # is assumed to refer to a scratch
557 Scratch files can be used just about anywhere a system or portable
558 file can be used. Also, portable files are now allowed in most
559 places that system files were allowed in previous PSPP version.
561 A new CLOSE FILE HANDLE command allows the storage associated with
562 scratch files to be freed. It also allows file handles to be
563 reassigned to new files.
565 For more information on scratch files, refer to the "File Handles"
566 section in the PSPP manual. For specifics of what commands now
567 allow what kinds of files to be specified, refer to the
568 documentation on those particular commands.
572 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
573 translation, are now supported. Use FILE HANDLE to specify the
574 format of these files.
576 * Little-endian, big-endian, and VAX-endian formats are now
577 supported for integer binary formats when reading and writing
578 data files. The new RIB and WIB subcommands on the SET command
579 control endianness of integer data. The default is the host's
582 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
583 floating point binary formats when reading and writing data
584 files. The new RRB and WRB subcommands on the SET command
585 control the floating point format. The default is the host's
586 native floating point format.
588 * DATA LIST now supports the SKIP subcommand, to skip records at
589 the beginning of a file. For compatibility, DATA LIST now
590 treats N format as F format for FREE and LIST format input.
592 * The SAVE and XSAVE commands now support the UNSELECTED,
593 PERMISSIONS, NAMES, and MAP subcommands.
595 * The EXPORT command has been re-implemented to obtain better
596 results. Support for the UNSELECTED, DIGITS, and TYPE
597 subcommands has been added.
599 * For compatibility, PRINT now inserts a space at the beginning of
600 every output line, even lines that would otherwise be blank,
601 when OUTFILE is specified. (The behavior of WRITE is
604 * For compatibility, PRINT EJECT now inserts the digit `1' at the
605 beginning of each line that should begin a new page.
607 * For compatibility, WRITE now outputs the system-missing value as
608 a field filled with spaces. Binary formats are an exception.
609 (The behavior of PRINT is unchanged.)
613 * Input and output format descriptions have been rewritten. They
614 now precisely describe what is accepted on input and written on
617 * The descriptions of the PSPP system and portable file formats
618 have been extensively revised and improved.
620 For developers, the build system now requires Autoconf 2.60 and
623 Changes from 0.3.0 to 0.4.0:
625 Changes in build dependencies:
627 * The GNU Scientific Library (libgsl), version 1.6 or later, is
630 * libplot from GNU plotutils is optional. Without it, the new
631 graphing features will not work. If you do not have it
632 installed, you must run `configure' with --without-libplot.
634 * libgmp2 is no longer a dependency.
636 Newly implemented commands and statistical features:
638 * EXAMINE, including its graphing features.
640 * FREQUENCIES now supports percentiles.
648 * SORT CASES now sorts stably, that is, two cases with equal sort
649 criteria will be in the same relative order before and after the
652 * T-TEST (re-written).
654 * DATE and USE. These commands are parsed but otherwise ignored,
655 to enhance compatibility with certain command files that invoke
658 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
659 currently have no effect on PSPP output, but their values are
660 written to and read from system files and thus may affect
661 third-party software.
663 * SET EPOCH implemented.
665 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
668 * FILE HANDLE now supports custom tab widths.
670 Long variable names (and other identifiers) are now supported. Up
671 to the first 64 bytes of each identifier is significant. PSPP now
672 reads and writes system files compatible with SPSS version 12.
674 New --algorithm and --syntax command line options allow
675 SPSS-compatible or enhanced modes to be selected.
677 Support for transformation expressions has been rewritten and
678 significantly improved. Refer to the manual for details.
680 Calculation of moments (mean, standard deviation, kurtosis,
681 skewness) has been rewritten and should now be more accurate. In
682 --algorithm=enhanced mode moments may be more accurate than SPSS in
685 Numerous bugs have been fixed, too many to mention here. Many new
686 tests have been added, leading to the discovery and fixing of many
689 The ASCII output driver can now squeeze multiple blank lines into
692 Much of the code has been rewritten and refactored. It is now much
695 The FILE TYPE and REPEATING DATA commands have been disabled for
696 this release because their implementations were deemed too buggy to
697 be useful. They will be fixed and replaced in a future release.
699 New pspp-mode for Emacs (in pspp-mode.el).
701 Added rudimentary command-line completion for interactive input.
703 lib/julcal and lib/dcdflib are no longer used, so they have been
706 For developers, the build system now requires Autoconf 2.58 and
707 Automake 1.7. The included gettext has been updated to version
710 Some reports state that Texinfo 4.8, the latest version, may be
711 necessary to successfully format the documentation on some systems.
713 Version 0.3.0 changes since 0.2.3:
717 * Using alphanumeric variables in functions under AGGREGATE
720 * Under certain circumstances, the final case would be omitted
721 from the results of an AGGREGATE operation. Fixed.
723 * Undefined behavior was invoked by referencing a freed pointer
724 under certain circumstances. Fixed.
726 * A wrong record size was displayed when paging the active file to
729 * Not having enough temporary space for sorting caused a core
732 * Syntax errors in function descriptions on AGGREGATE caused core
735 * A null pointer was dereferenced, causing a core dump, when
736 PERCENTILES was specified on FREQUENCIES. This fixes the
737 problem, but PSPP still doesn't calculate percentiles.
739 * SORT always sorted in ascending order. Fixed.
741 * Some minor memory leaks in the expression parser were removed.
743 * Many assertions fixed for strict ANSI C compliance.
747 * SET ECHO ON now implemented, but turned off by default.
749 * PRINT specifier supported on END REPEAT.
753 * System libgmp2 library is used if installed instead of
754 unconditionally using the included libgmp2 subset.
756 * Extensive code cleanup, which continues.
758 * Added CORRELATIONS command parser, but not implemented.
760 Version 0.2.3 changes since 0.2.2:
764 * SPLIT FILE with a string variable caused a core dump. Fixed.
766 * Nested INCLUDEs didn't work. Fixed.
768 * The MATCH FILES procedure set the values of variables not present
769 to 0. It should have been SYSMIS. This is now fixed.
771 * The REMARK command was too aggressive about skipping lines. It
772 didn't like being the last command in a file.
774 * Comment parsing wasn't consistent with the rest of the code in its
775 idea of where one command ends and another starts. This meant
776 that sometimes commands would be mysteriously ignored. Thanks to
777 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
779 * The TABLE subcommand on MATCH FILES worked only erratically at
780 best. This fixes it. Thanks to Dr. Dirk Melcher
781 <BZN-mdksh@t-online.de> for reporting this bug.
783 * VARIABLE LABELS rejected a slash before the first variable
784 specification, contradicting the documentation. Thanks to Walter
785 M. Gray <graywm@northernc.on.ca> for reporting this bug.
787 * Because of an incorrect optimization in memory allocation,
788 CROSSTABS sometimes segfaulted when asked to output multiple
789 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
792 * CROSSTABS didn't display value labels for column and row
793 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
796 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
797 <BZN-mdksh@t-online.de> for reporting this bug.
799 * The TABLE subcommand on MATCH FILES worked only erratically at
800 best. This fixes it. Thanks to Dr. Dirk Melcher
801 <BZN-mdksh@t-online.de> for reporting this bug.
803 * VARIABLE LABELS rejected a slash before the first variable
804 specification, contradicting the documentation. Thanks to Walter
