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 * The SYSFILE INFO command now accepts an ENCODING subcommand to
13 specify the character encoding of string data in the system file.
15 Changes from 0.8.1 to 0.8.2:
17 * Charts are now rendered with colours from the Tango palette instead
18 of fully saturated primaries.
20 * Support for new system file variants:
22 - PSPP can now read and write ZCOMPRESSED system files, which
23 compress data much more effectively than older "compressed"
24 files. (The older format is still supported.)
26 - PSPP can now decrypt encrypted system files, using the new
27 pspp-convert utility. The encrypted system file format is
28 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
29 do not directly read or write this format.
31 * Missing values for long string variables are now read from and
32 written to system files in an SPSS-compatible fashion.
34 (Earlier versions of PSPP that supported missing values for long
35 string variables wrote them to system files in an SPSS-incompatible
36 way. To fix the problem, read the system file with this version of
37 PSPP and then save a new copy of it.)
39 * pspp-convert, a new standalone utility for converting SPSS system
40 and portable files to other formats, is now included. The initial
41 version supports comma-separated value files as output format.
42 pspp-convert can also decrypt encrypted system files.
46 - zlib is now a required dependency. (Previously it was optional.)
48 Changes from 0.8.0 to 0.8.1:
54 * Changes to existing commands:
56 - CROSSTABS: The requirement that one expected count must be less than five
57 before Fishers Exact Test will be reported has been removed.
59 * PSPPIRE graphical user interface improvements:
61 - A new set of icons has been contributed.
63 - Syntax windows now parse syntax in "auto" mode, which in practice
64 should mean that both "batch" and "interactive" syntax now works,
65 instead of just "interactive" syntax.
67 - The variable pane of data windows now include a Role column.
71 - System files written by IBM SPSS 21 are now read without warnings.
73 - System files written by "VOXCO INTERVIEWER 4.3" are now read
76 - PSPPIRE should now more gracefully handle syntax files that contain
79 Changes from 0.6.2 to 0.8.0:
96 - PRESERVE and RESTORE
100 - SAVE TRANSLATE to CSV and tab-delimited files
102 - VARIABLE ATTRIBUTES
104 * Changes to existing commands:
106 - AUTORECODE has a new GROUP subcommand.
108 - CROSSTABS has been re-implemented to fix numerous bugs.
110 - EXAMINE: /MISSING=LISTWISE is now the default.
112 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
113 contains an INCLUDE or INSERT command, substitutions are not
114 applied to the included file.
116 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
118 - HOST has been updated to use more modern syntax.
120 - Most commands that work with data files now support a new
123 - MISSING VALUES can now assign missing values to long string
126 - ONEWAY: the POSTHOC subcommand is now implemented.
128 - The following new subcommands to NPAR TESTS have been implemented:
129 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
130 MCNEMAR, SIGN, WILCOXON, and RUNS
132 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
133 DPROMPT subcommands. The defaults are now fixed values.
135 - SHOW now has a JOURNAL subcommand, to show the location of the
138 - VALUE LABELS can now assign value labels to long string
141 * Other language changes:
143 - The new DATASET commands replace the "scratch file" PSPP
144 extension, which is no longer supported.
146 - Strings may now include arbitrary Unicode code points specified
147 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
148 code point U+1D11E, the musical G clef character, may be
149 expressed as U'1D11E'.
151 See the "Tokens" section in the PSPP manual for more information.
153 - In previous versions of PSPP, in a string expressed in
154 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
155 bytes in the locale encoding. In this version of PSPP, X'hh'
156 syntax always expresses bytes in UTF-8 encoding.
158 See the "Tokens" section in the PSPP manual for more information.
160 * PSPPIRE graphical user interface improvements:
162 - Added support for non-ASCII characters in strings, labels and
165 - A "Split Window" function is available, which makes it easier to
166 see different parts of a large data file.
168 - Data files can now be opened by specifing their name as the first
169 argument. This means that on a properly configured desktop, double
170 clicking on an icon will open the file.
172 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
173 via using an "intelligent" application assistant dialog.
177 - The new "cairo" output driver supports output in PostScript, PDF,
178 and SVG formats. Its functionality is a superset of that of the
179 "postscript" driver, which has been removed. You must have Cairo
180 and Pango installed to build the "cairo" driver.
182 - Charts are now produced with Cairo and Pango, instead of libplot.
183 Without them, the new graphing features will not work. If you do
184 not have Cairo and Pango installed, you must run `configure' with
187 - The plain text output driver now properly supports multibyte UTF-8
188 characters, including double-width characters and combining
191 - Output to OpenDocument format is now supported.
193 - The HTML output is much improved.
195 * The "pspp" program has a new option --batch (or -b) that selects
196 "batch" syntax mode. In previous versions of PSPP this syntax mode
197 was the default. Now a new "auto" syntax mode is the default. In
198 "auto" mode, PSPP interprets most syntax files correctly regardless
199 of their intended syntax mode.
201 See the "Syntax Variants" section in the PSPP manual for more
204 * The "pspp" program has a new option --syntax-encoding that
205 specifies the encoding for syntax files listed on the command line,
206 as well as the default encoding for syntax files included with
207 INCLUDE or INSERT. The default is to accept the system locale
208 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
209 one the system file uses.
211 See the documentation for the INSERT command in the PSPP manual for
214 * Text data files that PRINT and WRITE creates now use the system
215 native line ends by default (CRLF on Windows, LF only elsewhere).
216 Use the new ENDS subcommand on FILE HANDLE to override the default.
218 * A new Perl module allows Perl programs to read and write PSPP
221 * A tutorial chapter has been added to the user manual.
223 Changes from 0.6.1 to 0.6.2:
227 - Dutch, thanks to Harry Thijssen.
229 - Brazilian Portuguese, thanks to Michel Boaventura.
231 Thanks for translations are also due to the coordinators at
232 translationproject.org.
234 * Statistical bug fixes:
236 - REGRESSION: Report correct standard error of the estimate (bug
239 - T-TEST: Report correct significance of paired sample T-test in
240 the common case (bug #26936) and corner cases. Thanks to Mike
241 Griffiths and Matej Cepl for reporting these bugs.
243 * Build fixes and changes:
245 - Fix build with GTK+ 2.17.4 and later.
247 - Make running "make" after running "configure" with different
248 settings reliably rebuild version.c.
250 - Cygwin and MinGW build fixes.
252 - Fixes for building with recent gnulib.
254 - The Makefile now honors two new variables, PSPP_LDFLAGS and
255 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
256 binaries, respectively. This makes building easier for some
259 - Fixes for "configure --enable-relocatable" (bug #25508).
261 * Data file bug fixes and changes:
263 - Fix reading text data files that contain a mix of white space
264 and commas. Now "a ,b" is treated as two fields containing "a"
265 and "b"; previously it was treated as three, with an empty field
268 - Fix writing corrupted .sav files on Windows.
270 - Fix writing variable labels longer than 252 bytes to save files.
271 Thanks to Robert Westlund for reporting this bug.
273 - Fix writing corrupted .por files (bug #26034).
275 - Fix reading .por files whose initial lines are not padded out
276 with spaces as expected.
278 - PSPP will no longer issue warnings about some .sav file records
279 or values that it does not understand. These warnings were
280 harmless, but needlessly alarmed some users.
282 - Fix crash reading empty string fields from PostgreSQL databases.
284 * Bug fixes that affect PSPP and PSPPIRE:
286 - Users may now control precision of output statistics. Instead
287 of hard coding the width and decimals of output numbers, respect
288 the default format in most instances. Counts are now normally
289 displayed with the format of the weight variable, if any.
291 - Fix crash when an INSERT command specifies the name of a file
292 that does not exist (bug #24569).
294 - Fix crash when CROSSTABS specifies a long-string variable (bugs
297 - Fix crash drawing pie charts with many segments.
299 - Fix crash when NUMERIC specifies an invalid format.
301 * PSPPIRE bug fixes and changes:
303 - On Windows, write the output file to the user's home directory
304 instead of the current directory, to better match user
307 - Some data editor fixes.
311 - Fix typo in BINOMIAL section of user manual (bug #25892).
313 Changes from 0.6.0 to 0.6.1:
315 * Statistical bug fixes:
317 - Report correct standardized regression coefficients in linear
318 regression output (bug #23567).
320 * Bug fixes that affect PSPP and PSPPIRE:
322 - Avoid crash with pie charts (bug #24014).
324 - Don't append % to count totals (bug #24003).
326 - Don't crash on bad input (bug #24031).
328 - Don't crash if "end data." is not left aligned (bug #24115).
330 - Change default workspace value to 64 MB, to avoid unnecessary
331 disk accesses on modern machines.
335 - Add ".sav" or ".por" suffix to filename when saving with Save_As
338 - Make it possible to reopen the output window on Windows (bug
341 - A POSIX regular expression library is now included and used
342 automatically if the host does not have one or has one that is
345 * Build fixes and changes:
347 - Work around bug in GSL that prevented build with recent GCC
348 versions without manually adding -fgnu89-inline to CFLAGS.
350 - Also warn about missing prerequisites as we encounter them (bug
353 - Distribute necessary files to allow users working from the
354 distributed tarball to configure with --enable-gui-tools.
356 - Append $(EXEEXT_FOR_BUILD) to output file name when building
357 q2c, fixing build problems on Windows.
359 - GSL 1.8 or later is now required.
361 - Build errors with --enable-relocatable were fixed.
363 * The German translations were removed, since native German speakers
364 found them too poor to be useful.
366 Changes from 0.4.0 to 0.6.0:
368 * The PSPP license is now version 3 or later of the GNU General
369 Public License. Previously, it was version 2 or later.
371 * PSPP now has a graphical interface, called PSPPIRE. This
372 interface allows you to enter data and variable definitions
373 interactively. Commands may be executed in syntax form, or by
374 using the interactive dialog boxes available from the dropdown
377 * A few sample syntax files are now included in the `examples'
380 * Numerous major and minor bugs have been fixed.
384 * The INSTALL file now reflects the details of how to install
385 PSPP. It is a tailored version of the generic installation
386 instructions, instead of a verbatim copy.
388 * iconv, which is ordinarily installed as part of a Unix-like
389 system, is now required. If you don't have it already, you can
390 install GNU libiconv (http://www.gnu.org/software/libiconv/).
392 * libxml2 and zlib are new optional dependencies. They are
393 required to use PSPP's support for reading Gnumeric files.
395 Statistical procedure changes:
397 * REGRESSION is a new procedure for fitting linear models to data
398 via least-squares estimation.
400 * NPAR TESTS is a new procedure for non-parametric tests. In this
401 release, it supports binomial and chi-square tests.
403 * RANK is a new procedure to rank variables. It supports numerous
406 * FREQUENCIES can now output histograms and pie charts. These
407 features were present in earlier releases, but not documented.
409 User interface changes:
411 * In many situations where PSPP once terminated with a fatal
412 error, PSPP now recovers and continues execution.
414 * PSPP is now able to start up and run even if it cannot find its
417 * Journaling of interactive commands to a disk file is now
418 implemented. By default, journaling is enabled, to a file named
419 `pspp.jnl' in the current directory. SET JOURNAL may be used to
422 * The use of `+' between syntax file names on the command line to
423 prevent the dictionary from being cleared between their
424 executions is no longer supported. All syntax files are now
425 executed as if `+' had been specified.
427 * The -d/--define and -u/--undef command line options are no
428 longer supported. Instead, use /usr/bin/env or shell primitives
429 to define or clear environment variables before invoking PSPP.
431 * If a syntax file named named `rc' is found in a configuration
432 directory (such as $HOME/.pspp), it is executed before any
433 syntax file specified on the command line. The -r or
434 --no-statrc command line option may be used to disable this
439 * Output configuration options have changed. Please refer to the
440 manual for a full description of the available options.
442 In consequence, you will need to reinstall your "devices" file.
443 "make install" will do this for you.
445 * Most error messages are now written to PSPP output files by
446 default. SET ERROR can be used to disable this behavior.
448 * When invoked interactively, PSPP now by default produces output
449 on the terminal, piping it through the "more" program.
450 Previously, by default output was written only to file
451 pspp.list. On most terminals, the page length used for output
452 automatically adapts to the terminal size, even if the terminal
457 - This driver now supports charts in output. Charts are written
458 as separate files that the main output file refers to. By
459 default, charts are written in PNG format to files named
460 pspp-1.png, pspp-2.png, and so on.
462 - Configurations are provided that use VT100 (and xterm)
463 line-drawing characters in tables. The option "-o list-vt100"
464 requests use of this device for output to pspp.list.
468 - The default paper size is now determined using the PAPERSIZE
469 environment variable, or the LC_PAPER locale category on
470 systems that support it. If these are not set, the default is
471 now A4, instead of US letter. To make US letter the default,
472 set PAPERSIZE to "letter" in your environment.
474 - Font metrics are now read from AFM files, instead of
475 Groff-format metrics files. PostScript fonts can now be
478 In consequence, you will need to install an AFM file for each
479 font used in PostScript output. "make install" will install
480 AFM files for the standard PostScript fonts, including the
481 ones that the PostScript driver uses by default.
483 - Standard paper sizes no longer need to be specified through a
484 configuration file. The "papersize" configuration file is no
485 longer needed, or supported.
487 - The PostScript prologue is no longer obtained from the
488 "ps-prologue" configuration file. This configuration file is
489 no longer needed, or supported.
493 - The HTML prologue is no longer obtained from the
494 "html-prologue" configuration file. This configuration file
495 is no longer needed, or supported.
497 Command language changes:
499 * The following commands are new:
501 - GET DATA, which currently supports reading Gnumeric files and
502 text data files. It will be extended later to read other
503 types of foreign data.
505 - CD, to change the current directory.
507 - INSERT, to execute a syntax file.
509 - DELETE VARIABLES, to remove variables from the active file
512 - ADD DOCUMENT, to add text to active file documents.
514 - CLOSE FILE HANDLE (a PSPP extension; see below).
516 - XEXPORT, a PSPP extension that is a transformation equivalent
519 * The following functions for transformation expressions are new:
521 - DATEDIFF, for computing the difference of two dates.
523 - DATESUM, for advancing a date by a specified duration.
525 - VALUELABEL, to obtain the value label for a value.
527 * PSPP now supports very long string variables (over 255 bytes
530 * MATCH FILES now supports the FIRST and LAST subcommands.
532 * Previous versions of PSPP prohibited using commands to both read and
533 write a single file at the same time. Now, PSPP allows this, and
534 the new version of the file atomically replaces the old version.
536 * The following commands are no longer available. They will be
537 re-implemented in a later release:
539 - CLEAR TRANSFORMATIONS
545 * The PROCESS IF command, which was deprecated, has been removed.
546 You may replace any usage of it by SELECT IF following
547 TEMPORARY, which has the same effect.
549 * The output format for variables created by VECTOR may now be
550 specified as part of the VECTOR syntax.
552 "Scratch files", a new PSPP extension:
554 A scratch file, like a system file, consists of a dictionary and
555 any number of cases. Small scratch files are stored in memory;
556 one that grows too large is written to disk. By default, any file
557 handle whose name begins with # is assumed to refer to a scratch
560 Scratch files can be used just about anywhere a system or portable
561 file can be used. Also, portable files are now allowed in most
562 places that system files were allowed in previous PSPP version.
564 A new CLOSE FILE HANDLE command allows the storage associated with
565 scratch files to be freed. It also allows file handles to be
566 reassigned to new files.
568 For more information on scratch files, refer to the "File Handles"
569 section in the PSPP manual. For specifics of what commands now
570 allow what kinds of files to be specified, refer to the
571 documentation on those particular commands.
575 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
576 translation, are now supported. Use FILE HANDLE to specify the
577 format of these files.
579 * Little-endian, big-endian, and VAX-endian formats are now
580 supported for integer binary formats when reading and writing
581 data files. The new RIB and WIB subcommands on the SET command
582 control endianness of integer data. The default is the host's
585 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
586 floating point binary formats when reading and writing data
587 files. The new RRB and WRB subcommands on the SET command
588 control the floating point format. The default is the host's
589 native floating point format.
591 * DATA LIST now supports the SKIP subcommand, to skip records at
592 the beginning of a file. For compatibility, DATA LIST now
593 treats N format as F format for FREE and LIST format input.
595 * The SAVE and XSAVE commands now support the UNSELECTED,
596 PERMISSIONS, NAMES, and MAP subcommands.
598 * The EXPORT command has been re-implemented to obtain better
599 results. Support for the UNSELECTED, DIGITS, and TYPE
600 subcommands has been added.
602 * For compatibility, PRINT now inserts a space at the beginning of
603 every output line, even lines that would otherwise be blank,
604 when OUTFILE is specified. (The behavior of WRITE is
607 * For compatibility, PRINT EJECT now inserts the digit `1' at the
608 beginning of each line that should begin a new page.
610 * For compatibility, WRITE now outputs the system-missing value as
611 a field filled with spaces. Binary formats are an exception.
612 (The behavior of PRINT is unchanged.)
616 * Input and output format descriptions have been rewritten. They
617 now precisely describe what is accepted on input and written on
620 * The descriptions of the PSPP system and portable file formats
621 have been extensively revised and improved.
623 For developers, the build system now requires Autoconf 2.60 and
626 Changes from 0.3.0 to 0.4.0:
628 Changes in build dependencies:
630 * The GNU Scientific Library (libgsl), version 1.6 or later, is
633 * libplot from GNU plotutils is optional. Without it, the new
634 graphing features will not work. If you do not have it
635 installed, you must run `configure' with --without-libplot.
637 * libgmp2 is no longer a dependency.
639 Newly implemented commands and statistical features:
641 * EXAMINE, including its graphing features.
643 * FREQUENCIES now supports percentiles.
651 * SORT CASES now sorts stably, that is, two cases with equal sort
652 criteria will be in the same relative order before and after the
655 * T-TEST (re-written).
657 * DATE and USE. These commands are parsed but otherwise ignored,
658 to enhance compatibility with certain command files that invoke
661 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
662 currently have no effect on PSPP output, but their values are
663 written to and read from system files and thus may affect
664 third-party software.
666 * SET EPOCH implemented.
668 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
671 * FILE HANDLE now supports custom tab widths.
673 Long variable names (and other identifiers) are now supported. Up
674 to the first 64 bytes of each identifier is significant. PSPP now
675 reads and writes system files compatible with SPSS version 12.
677 New --algorithm and --syntax command line options allow
678 SPSS-compatible or enhanced modes to be selected.
680 Support for transformation expressions has been rewritten and
681 significantly improved. Refer to the manual for details.
683 Calculation of moments (mean, standard deviation, kurtosis,
684 skewness) has been rewritten and should now be more accurate. In
685 --algorithm=enhanced mode moments may be more accurate than SPSS in
688 Numerous bugs have been fixed, too many to mention here. Many new
689 tests have been added, leading to the discovery and fixing of many
692 The ASCII output driver can now squeeze multiple blank lines into
695 Much of the code has been rewritten and refactored. It is now much
698 The FILE TYPE and REPEATING DATA commands have been disabled for
699 this release because their implementations were deemed too buggy to
700 be useful. They will be fixed and replaced in a future release.
702 New pspp-mode for Emacs (in pspp-mode.el).
704 Added rudimentary command-line completion for interactive input.
706 lib/julcal and lib/dcdflib are no longer used, so they have been
709 For developers, the build system now requires Autoconf 2.58 and
710 Automake 1.7. The included gettext has been updated to version
713 Some reports state that Texinfo 4.8, the latest version, may be
714 necessary to successfully format the documentation on some systems.
716 Version 0.3.0 changes since 0.2.3:
720 * Using alphanumeric variables in functions under AGGREGATE
723 * Under certain circumstances, the final case would be omitted
724 from the results of an AGGREGATE operation. Fixed.
726 * Undefined behavior was invoked by referencing a freed pointer
727 under certain circumstances. Fixed.
729 * A wrong record size was displayed when paging the active file to
732 * Not having enough temporary space for sorting caused a core
735 * Syntax errors in function descriptions on AGGREGATE caused core
738 * A null pointer was dereferenced, causing a core dump, when
739 PERCENTILES was specified on FREQUENCIES. This fixes the
740 problem, but PSPP still doesn't calculate percentiles.
742 * SORT always sorted in ascending order. Fixed.
744 * Some minor memory leaks in the expression parser were removed.
746 * Many assertions fixed for strict ANSI C compliance.
750 * SET ECHO ON now implemented, but turned off by default.
752 * PRINT specifier supported on END REPEAT.
756 * System libgmp2 library is used if installed instead of
757 unconditionally using the included libgmp2 subset.
759 * Extensive code cleanup, which continues.
761 * Added CORRELATIONS command parser, but not implemented.
763 Version 0.2.3 changes since 0.2.2:
767 * SPLIT FILE with a string variable caused a core dump. Fixed.
769 * Nested INCLUDEs didn't work. Fixed.
771 * The MATCH FILES procedure set the values of variables not present
772 to 0. It should have been SYSMIS. This is now fixed.
774 * The REMARK command was too aggressive about skipping lines. It
775 didn't like being the last command in a file.
777 * Comment parsing wasn't consistent with the rest of the code in its
778 idea of where one command ends and another starts. This meant
779 that sometimes commands would be mysteriously ignored. Thanks to
780 Dr. Dirk Melcher <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 * The TABLE subcommand on MATCH FILES worked only erratically at
803 best. This fixes it. Thanks to Dr. Dirk Melcher
804 <BZN-mdksh@t-online.de> for reporting this bug.
