5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
9 * PSPPIRE graphical user interface improvements:
11 - Syntax windows now parse syntax in "auto" mode, which in practice
12 should mean that both "batch" and "interactive" syntax now works,
13 instead of just "interactive" syntax.
15 Changes from 0.6.2 to 0.8.0:
32 - PRESERVE and RESTORE
36 - SAVE TRANSLATE to CSV and tab-delimited files
40 * Changes to existing commands:
42 - AUTORECODE has a new GROUP subcommand.
44 - CROSSTABS has been re-implemented to fix numerous bugs.
46 - EXAMINE: /MISSING=LISTWISE is now the default.
48 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
49 contains an INCLUDE or INSERT command, substitutions are not
50 applied to the included file.
52 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
54 - HOST has been updated to use more modern syntax.
56 - Most commands that work with data files now support a new
59 - MISSING VALUES can now assign missing values to long string
62 - ONEWAY: the POSTHOC subcommand is now implemented.
64 - The following new subcommands to NPAR TESTS have been implemented:
65 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
66 MCNEMAR, SIGN, WILCOXON, and RUNS
68 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
69 DPROMPT subcommands. The defaults are now fixed values.
71 - SHOW now has a JOURNAL subcommand, to show the location of the
74 - VALUE LABELS can now assign value labels to long string
77 * Other language changes:
79 - The new DATASET commands replace the "scratch file" PSPP
80 extension, which is no longer supported.
82 - Strings may now include arbitrary Unicode code points specified
83 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
84 code point U+1D11E, the musical G clef character, may be
85 expressed as U'1D11E'.
87 See the "Tokens" section in the PSPP manual for more information.
89 - In previous versions of PSPP, in a string expressed in
90 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
91 bytes in the locale encoding. In this version of PSPP, X'hh'
92 syntax always expresses bytes in UTF-8 encoding.
94 See the "Tokens" section in the PSPP manual for more information.
96 * PSPPIRE graphical user interface improvements:
98 - Added support for non-ASCII characters in strings, labels and
101 - A "Split Window" function is available, which makes it easier to
102 see different parts of a large data file.
104 - Data files can now be opened by specifing their name as the first
105 argument. This means that on a properly configured desktop, double
106 clicking on an icon will open the file.
108 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
109 via using an "intelligent" application assistant dialog.
113 - The new "cairo" output driver supports output in PostScript, PDF,
114 and SVG formats. Its functionality is a superset of that of the
115 "postscript" driver, which has been removed. You must have Cairo
116 and Pango installed to build the "cairo" driver.
118 - Charts are now produced with Cairo and Pango, instead of libplot.
119 Without them, the new graphing features will not work. If you do
120 not have Cairo and Pango installed, you must run `configure' with
123 - The plain text output driver now properly supports multibyte UTF-8
124 characters, including double-width characters and combining
127 - Output to OpenDocument format is now supported.
129 - The HTML output is much improved.
131 * The "pspp" program has a new option --batch (or -b) that selects
132 "batch" syntax mode. In previous versions of PSPP this syntax mode
133 was the default. Now a new "auto" syntax mode is the default. In
134 "auto" mode, PSPP interprets most syntax files correctly regardless
135 of their intended syntax mode.
137 See the "Syntax Variants" section in the PSPP manual for more
140 * The "pspp" program has a new option --syntax-encoding that
141 specifies the encoding for syntax files listed on the command line,
142 as well as the default encoding for syntax files included with
143 INCLUDE or INSERT. The default is to accept the system locale
144 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
145 one the system file uses.
147 See the documentation for the INSERT command in the PSPP manual for
150 * Text data files that PRINT and WRITE creates now use the system
151 native line ends by default (CRLF on Windows, LF only elsewhere).
152 Use the new ENDS subcommand on FILE HANDLE to override the default.
154 * A new Perl module allows Perl programs to read and write PSPP
157 * A tutorial chapter has been added to the user manual.
159 Changes from 0.6.1 to 0.6.2:
163 - Dutch, thanks to Harry Thijssen.
165 - Brazilian Portuguese, thanks to Michel Boaventura.
167 Thanks for translations are also due to the coordinators at
168 translationproject.org.
170 * Statistical bug fixes:
172 - REGRESSION: Report correct standard error of the estimate (bug
175 - T-TEST: Report correct significance of paired sample T-test in
176 the common case (bug #26936) and corner cases. Thanks to Mike
177 Griffiths and Matej Cepl for reporting these bugs.
179 * Build fixes and changes:
181 - Fix build with GTK+ 2.17.4 and later.
183 - Make running "make" after running "configure" with different
184 settings reliably rebuild version.c.
186 - Cygwin and MinGW build fixes.
188 - Fixes for building with recent gnulib.
190 - The Makefile now honors two new variables, PSPP_LDFLAGS and
191 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
192 binaries, respectively. This makes building easier for some
195 - Fixes for "configure --enable-relocatable" (bug #25508).
197 * Data file bug fixes and changes:
199 - Fix reading text data files that contain a mix of white space
200 and commas. Now "a ,b" is treated as two fields containing "a"
201 and "b"; previously it was treated as three, with an empty field
204 - Fix writing corrupted .sav files on Windows.
206 - Fix writing variable labels longer than 252 bytes to save files.
207 Thanks to Robert Westlund for reporting this bug.
209 - Fix writing corrupted .por files (bug #26034).
211 - Fix reading .por files whose initial lines are not padded out
212 with spaces as expected.
214 - PSPP will no longer issue warnings about some .sav file records
215 or values that it does not understand. These warnings were
216 harmless, but needlessly alarmed some users.
218 - Fix crash reading empty string fields from PostgreSQL databases.
220 * Bug fixes that affect PSPP and PSPPIRE:
222 - Users may now control precision of output statistics. Instead
223 of hard coding the width and decimals of output numbers, respect
224 the default format in most instances. Counts are now normally
225 displayed with the format of the weight variable, if any.
227 - Fix crash when an INSERT command specifies the name of a file
228 that does not exist (bug #24569).
230 - Fix crash when CROSSTABS specifies a long-string variable (bugs
233 - Fix crash drawing pie charts with many segments.
235 - Fix crash when NUMERIC specifies an invalid format.
237 * PSPPIRE bug fixes and changes:
239 - On Windows, write the output file to the user's home directory
240 instead of the current directory, to better match user
243 - Some data editor fixes.
247 - Fix typo in BINOMIAL section of user manual (bug #25892).
249 Changes from 0.6.0 to 0.6.1:
251 * Statistical bug fixes:
253 - Report correct standardized regression coefficients in linear
254 regression output (bug #23567).
256 * Bug fixes that affect PSPP and PSPPIRE:
258 - Avoid crash with pie charts (bug #24014).
260 - Don't append % to count totals (bug #24003).
262 - Don't crash on bad input (bug #24031).
264 - Don't crash if "end data." is not left aligned (bug #24115).
266 - Change default workspace value to 64 MB, to avoid unnecessary
267 disk accesses on modern machines.
271 - Add ".sav" or ".por" suffix to filename when saving with Save_As
274 - Make it possible to reopen the output window on Windows (bug
277 - A POSIX regular expression library is now included and used
278 automatically if the host does not have one or has one that is
281 * Build fixes and changes:
283 - Work around bug in GSL that prevented build with recent GCC
284 versions without manually adding -fgnu89-inline to CFLAGS.
286 - Also warn about missing prerequisites as we encounter them (bug
289 - Distribute necessary files to allow users working from the
290 distributed tarball to configure with --enable-gui-tools.
292 - Append $(EXEEXT_FOR_BUILD) to output file name when building
293 q2c, fixing build problems on Windows.
295 - GSL 1.8 or later is now required.
297 - Build errors with --enable-relocatable were fixed.
299 * The German translations were removed, since native German speakers
300 found them too poor to be useful.
302 Changes from 0.4.0 to 0.6.0:
304 * The PSPP license is now version 3 or later of the GNU General
305 Public License. Previously, it was version 2 or later.
307 * PSPP now has a graphical interface, called PSPPIRE. This
308 interface allows you to enter data and variable definitions
309 interactively. Commands may be executed in syntax form, or by
310 using the interactive dialog boxes available from the dropdown
313 * A few sample syntax files are now included in the `examples'
316 * Numerous major and minor bugs have been fixed.
320 * The INSTALL file now reflects the details of how to install
321 PSPP. It is a tailored version of the generic installation
322 instructions, instead of a verbatim copy.
324 * iconv, which is ordinarily installed as part of a Unix-like
325 system, is now required. If you don't have it already, you can
326 install GNU libiconv (http://www.gnu.org/software/libiconv/).
328 * libxml2 and zlib are new optional dependencies. They are
329 required to use PSPP's support for reading Gnumeric files.
331 Statistical procedure changes:
333 * REGRESSION is a new procedure for fitting linear models to data
334 via least-squares estimation.
336 * NPAR TESTS is a new procedure for non-parametric tests. In this
337 release, it supports binomial and chi-square tests.
339 * RANK is a new procedure to rank variables. It supports numerous
342 * FREQUENCIES can now output histograms and pie charts. These
343 features were present in earlier releases, but not documented.
345 User interface changes:
347 * In many situations where PSPP once terminated with a fatal
348 error, PSPP now recovers and continues execution.
350 * PSPP is now able to start up and run even if it cannot find its
353 * Journaling of interactive commands to a disk file is now
354 implemented. By default, journaling is enabled, to a file named
355 `pspp.jnl' in the current directory. SET JOURNAL may be used to
358 * The use of `+' between syntax file names on the command line to
359 prevent the dictionary from being cleared between their
360 executions is no longer supported. All syntax files are now
361 executed as if `+' had been specified.
363 * The -d/--define and -u/--undef command line options are no
364 longer supported. Instead, use /usr/bin/env or shell primitives
365 to define or clear environment variables before invoking PSPP.
367 * If a syntax file named named `rc' is found in a configuration
368 directory (such as $HOME/.pspp), it is executed before any
369 syntax file specified on the command line. The -r or
370 --no-statrc command line option may be used to disable this
375 * Output configuration options have changed. Please refer to the
376 manual for a full description of the available options.
378 In consequence, you will need to reinstall your "devices" file.
379 "make install" will do this for you.
381 * Most error messages are now written to PSPP output files by
382 default. SET ERROR can be used to disable this behavior.
384 * When invoked interactively, PSPP now by default produces output
385 on the terminal, piping it through the "more" program.
386 Previously, by default output was written only to file
387 pspp.list. On most terminals, the page length used for output
388 automatically adapts to the terminal size, even if the terminal
393 - This driver now supports charts in output. Charts are written
394 as separate files that the main output file refers to. By
395 default, charts are written in PNG format to files named
396 pspp-1.png, pspp-2.png, and so on.
398 - Configurations are provided that use VT100 (and xterm)
399 line-drawing characters in tables. The option "-o list-vt100"
400 requests use of this device for output to pspp.list.
404 - The default paper size is now determined using the PAPERSIZE
405 environment variable, or the LC_PAPER locale category on
406 systems that support it. If these are not set, the default is
407 now A4, instead of US letter. To make US letter the default,
408 set PAPERSIZE to "letter" in your environment.
410 - Font metrics are now read from AFM files, instead of
411 Groff-format metrics files. PostScript fonts can now be
414 In consequence, you will need to install an AFM file for each
415 font used in PostScript output. "make install" will install
416 AFM files for the standard PostScript fonts, including the
417 ones that the PostScript driver uses by default.
419 - Standard paper sizes no longer need to be specified through a
420 configuration file. The "papersize" configuration file is no
421 longer needed, or supported.
423 - The PostScript prologue is no longer obtained from the
424 "ps-prologue" configuration file. This configuration file is
425 no longer needed, or supported.
429 - The HTML prologue is no longer obtained from the
430 "html-prologue" configuration file. This configuration file
431 is no longer needed, or supported.
433 Command language changes:
435 * The following commands are new:
437 - GET DATA, which currently supports reading Gnumeric files and
438 text data files. It will be extended later to read other
439 types of foreign data.
441 - CD, to change the current directory.
443 - INSERT, to execute a syntax file.
445 - DELETE VARIABLES, to remove variables from the active file
448 - ADD DOCUMENT, to add text to active file documents.
450 - CLOSE FILE HANDLE (a PSPP extension; see below).
452 - XEXPORT, a PSPP extension that is a transformation equivalent
455 * The following functions for transformation expressions are new:
457 - DATEDIFF, for computing the difference of two dates.
459 - DATESUM, for advancing a date by a specified duration.
461 - VALUELABEL, to obtain the value label for a value.
463 * PSPP now supports very long string variables (over 255 bytes
466 * MATCH FILES now supports the FIRST and LAST subcommands.
468 * Previous versions of PSPP prohibited using commands to both read and
469 write a single file at the same time. Now, PSPP allows this, and
470 the new version of the file atomically replaces the old version.
472 * The following commands are no longer available. They will be
473 re-implemented in a later release:
475 - CLEAR TRANSFORMATIONS
481 * The PROCESS IF command, which was deprecated, has been removed.
482 You may replace any usage of it by SELECT IF following
483 TEMPORARY, which has the same effect.
485 * The output format for variables created by VECTOR may now be
486 specified as part of the VECTOR syntax.
488 "Scratch files", a new PSPP extension:
490 A scratch file, like a system file, consists of a dictionary and
491 any number of cases. Small scratch files are stored in memory;
492 one that grows too large is written to disk. By default, any file
493 handle whose name begins with # is assumed to refer to a scratch
496 Scratch files can be used just about anywhere a system or portable
497 file can be used. Also, portable files are now allowed in most
498 places that system files were allowed in previous PSPP version.
500 A new CLOSE FILE HANDLE command allows the storage associated with
501 scratch files to be freed. It also allows file handles to be
502 reassigned to new files.
504 For more information on scratch files, refer to the "File Handles"
505 section in the PSPP manual. For specifics of what commands now
506 allow what kinds of files to be specified, refer to the
507 documentation on those particular commands.
511 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
512 translation, are now supported. Use FILE HANDLE to specify the
513 format of these files.
515 * Little-endian, big-endian, and VAX-endian formats are now
516 supported for integer binary formats when reading and writing
517 data files. The new RIB and WIB subcommands on the SET command
518 control endianness of integer data. The default is the host's
521 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
522 floating point binary formats when reading and writing data
523 files. The new RRB and WRB subcommands on the SET command
524 control the floating point format. The default is the host's
525 native floating point format.
527 * DATA LIST now supports the SKIP subcommand, to skip records at
528 the beginning of a file. For compatibility, DATA LIST now
529 treats N format as F format for FREE and LIST format input.
531 * The SAVE and XSAVE commands now support the UNSELECTED,
532 PERMISSIONS, NAMES, and MAP subcommands.
534 * The EXPORT command has been re-implemented to obtain better
535 results. Support for the UNSELECTED, DIGITS, and TYPE
536 subcommands has been added.
538 * For compatibility, PRINT now inserts a space at the beginning of
539 every output line, even lines that would otherwise be blank,
540 when OUTFILE is specified. (The behavior of WRITE is
543 * For compatibility, PRINT EJECT now inserts the digit `1' at the
544 beginning of each line that should begin a new page.
546 * For compatibility, WRITE now outputs the system-missing value as
547 a field filled with spaces. Binary formats are an exception.
548 (The behavior of PRINT is unchanged.)
552 * Input and output format descriptions have been rewritten. They
553 now precisely describe what is accepted on input and written on
556 * The descriptions of the PSPP system and portable file formats
557 have been extensively revised and improved.
559 For developers, the build system now requires Autoconf 2.60 and
562 Changes from 0.3.0 to 0.4.0:
564 Changes in build dependencies:
566 * The GNU Scientific Library (libgsl), version 1.6 or later, is
569 * libplot from GNU plotutils is optional. Without it, the new
570 graphing features will not work. If you do not have it
571 installed, you must run `configure' with --without-libplot.
573 * libgmp2 is no longer a dependency.
575 Newly implemented commands and statistical features:
577 * EXAMINE, including its graphing features.
579 * FREQUENCIES now supports percentiles.
587 * SORT CASES now sorts stably, that is, two cases with equal sort
588 criteria will be in the same relative order before and after the
591 * T-TEST (re-written).
593 * DATE and USE. These commands are parsed but otherwise ignored,
594 to enhance compatibility with certain command files that invoke
597 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
598 currently have no effect on PSPP output, but their values are
599 written to and read from system files and thus may affect
600 third-party software.
602 * SET EPOCH implemented.
604 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
607 * FILE HANDLE now supports custom tab widths.
609 Long variable names (and other identifiers) are now supported. Up
610 to the first 64 bytes of each identifier is significant. PSPP now
611 reads and writes system files compatible with SPSS version 12.
613 New --algorithm and --syntax command line options allow
614 SPSS-compatible or enhanced modes to be selected.
616 Support for transformation expressions has been rewritten and
617 significantly improved. Refer to the manual for details.
619 Calculation of moments (mean, standard deviation, kurtosis,
620 skewness) has been rewritten and should now be more accurate. In
621 --algorithm=enhanced mode moments may be more accurate than SPSS in
624 Numerous bugs have been fixed, too many to mention here. Many new
625 tests have been added, leading to the discovery and fixing of many
628 The ASCII output driver can now squeeze multiple blank lines into
631 Much of the code has been rewritten and refactored. It is now much
634 The FILE TYPE and REPEATING DATA commands have been disabled for
635 this release because their implementations were deemed too buggy to
636 be useful. They will be fixed and replaced in a future release.
638 New pspp-mode for Emacs (in pspp-mode.el).
640 Added rudimentary command-line completion for interactive input.
642 lib/julcal and lib/dcdflib are no longer used, so they have been
645 For developers, the build system now requires Autoconf 2.58 and
646 Automake 1.7. The included gettext has been updated to version
649 Some reports state that Texinfo 4.8, the latest version, may be
650 necessary to successfully format the documentation on some systems.
652 Version 0.3.0 changes since 0.2.3:
656 * Using alphanumeric variables in functions under AGGREGATE
659 * Under certain circumstances, the final case would be omitted
660 from the results of an AGGREGATE operation. Fixed.
662 * Undefined behavior was invoked by referencing a freed pointer
663 under certain circumstances. Fixed.
665 * A wrong record size was displayed when paging the active file to
668 * Not having enough temporary space for sorting caused a core
671 * Syntax errors in function descriptions on AGGREGATE caused core
674 * A null pointer was dereferenced, causing a core dump, when
675 PERCENTILES was specified on FREQUENCIES. This fixes the
676 problem, but PSPP still doesn't calculate percentiles.
678 * SORT always sorted in ascending order. Fixed.
680 * Some minor memory leaks in the expression parser were removed.
682 * Many assertions fixed for strict ANSI C compliance.
686 * SET ECHO ON now implemented, but turned off by default.
688 * PRINT specifier supported on END REPEAT.
692 * System libgmp2 library is used if installed instead of
693 unconditionally using the included libgmp2 subset.
695 * Extensive code cleanup, which continues.
697 * Added CORRELATIONS command parser, but not implemented.
699 Version 0.2.3 changes since 0.2.2:
703 * SPLIT FILE with a string variable caused a core dump. Fixed.
705 * Nested INCLUDEs didn't work. Fixed.
707 * The MATCH FILES procedure set the values of variables not present
708 to 0. It should have been SYSMIS. This is now fixed.
710 * The REMARK command was too aggressive about skipping lines. It
711 didn't like being the last command in a file.
713 * Comment parsing wasn't consistent with the rest of the code in its
714 idea of where one command ends and another starts. This meant
715 that sometimes commands would be mysteriously ignored. Thanks to
716 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
718 * The TABLE subcommand on MATCH FILES worked only erratically at
719 best. This fixes it. Thanks to Dr. Dirk Melcher
720 <BZN-mdksh@t-online.de> for reporting this bug.
722 * VARIABLE LABELS rejected a slash before the first variable
723 specification, contradicting the documentation. Thanks to Walter
724 M. Gray <graywm@northernc.on.ca> for reporting this bug.
726 * Because of an incorrect optimization in memory allocation,
727 CROSSTABS sometimes segfaulted when asked to output multiple
728 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
731 * CROSSTABS didn't display value labels for column and row
732 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
735 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
736 <BZN-mdksh@t-online.de> for reporting this bug.
738 * The TABLE subcommand on MATCH FILES worked only erratically at
739 best. This fixes it. Thanks to Dr. Dirk Melcher
740 <BZN-mdksh@t-online.de> for reporting this bug.
742 * VARIABLE LABELS rejected a slash before the first variable
743 specification, contradicting the documentation. Thanks to Walter
744 M. Gray <graywm@northernc.on.ca> for reporting this bug.
746 * Because of an incorrect optimization in memory allocation,
747 CROSSTABS sometimes segfaulted when asked to output multiple
748 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
751 * CROSSTABS didn't display value labels for column and row
752 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
755 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
756 <BZN-mdksh@t-online.de> for reporting this bug.
758 * MATCH FILES corrupted memory and dumped core on some syntax
761 * MATCH FILES should set numeric values not available to the
762 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
763 <BZN-mdksh@t-online.de> for reporting this bug.
765 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
766 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
770 * Some systems didn't like the way open_file was coded. Thanks to
771 Hankin <hankin@rogue.consultco.com> for pointing this out.
773 * The SAVE procedure didn't save long string variables properly.
774 Fixed by this patch. Thanks to Hankin
775 <hankin@rogue.consultco.com> for this patch.
777 * Minor documentation fixes for MATCH FILES.
779 Version 0.2.2 changes since 0.2.1:
783 * Fix behavior of PRINT SPACE for negative arguments.
785 * Fix reading some unusual system files.
787 * Fix LIST problems with very long variables. Thanks to Hankin
788 <hankin@dunno.com> for this bug report.
790 * Fix problems with some string format specifiers.
792 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
793 <BZN-mdksh@t-online.de> for reporting this bug.
795 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
796 Hankin <hankin@dunno.com> again on this one.
