7 Changes from 0.6.2 to 0.7.9:
24 - PRESERVE and RESTORE
28 - SAVE TRANSLATE to CSV and tab-delimited files
32 * Changes to existing commands:
34 - AUTORECODE has a new GROUP subcommand.
36 - CROSSTABS has been re-implemented to fix numerous bugs.
38 - EXAMINE: /MISSING=LISTWISE is now the default.
40 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
41 contains an INCLUDE or INSERT command, substitutions are not
42 applied to the included file.
44 - HOST has been updated to use more modern syntax.
46 - Most commands that work with data files now support a new
49 - MISSING VALUES can now assign missing values to long string
52 - ONEWAY: the POSTHOC subcommand is now implemented.
54 - The following new subcommands to NPAR TESTS have been implemented:
55 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
56 MCNEMAR, SIGN, WILCOXON, and RUNS
58 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
59 DPROMPT subcommands. The defaults are now fixed values.
61 - SHOW now has a JOURNAL subcommand, to show the location of the
64 - VALUE LABELS can now assign value labels to long string
67 * Other language changes:
69 - The new DATASET commands replace the "scratch file" PSPP
70 extension, which is no longer supported.
72 - Strings may now include arbitrary Unicode code points specified
73 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
74 code point U+1D11E, the musical G clef character, may be
75 expressed as U'1D11E'.
77 See the "Tokens" section in the PSPP manual for more information.
79 - In previous versions of PSPP, in a string expressed in
80 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
81 bytes in the locale encoding. In this version of PSPP, X'hh'
82 syntax always expresses bytes in UTF-8 encoding.
84 See the "Tokens" section in the PSPP manual for more information.
86 * PSPPIRE graphical user interface improvements:
88 - Added support for non-ASCII characters in strings, labels and
91 - A "Split Window" function is available, which makes it easier to
92 see different parts of a large data file.
94 - Data files can now be opened by specifing their name as the first
95 argument. This means that on a properly configured desktop, double
96 clicking on an icon will open the file.
100 - The new "cairo" output driver supports output in PostScript, PDF,
101 and SVG formats. Its functionality is a superset of that of the
102 "postscript" driver, which has been removed. You must have Cairo
103 and Pango installed to build the "cairo" driver.
105 - Charts are now produced with Cairo and Pango, instead of libplot.
106 Without them, the new graphing features will not work. If you do
107 not have Cairo and Pango installed, you must run `configure' with
110 - The plain text output driver now properly supports multibyte UTF-8
111 characters, including double-width characters and combining
114 - Output to OpenDocument format is now supported.
116 - The HTML output is much improved.
118 * The "pspp" program has a new option --batch (or -b) that selects
119 "batch" syntax mode. In previous versions of PSPP this syntax mode
120 was the default. Now a new "auto" syntax mode is the default. In
121 "auto" mode, PSPP interprets most syntax files correctly regardless
122 of their intended syntax mode.
124 See the "Syntax Variants" section in the PSPP manual for more
127 * The "pspp" program has a new option --syntax-encoding that
128 specifies the encoding for syntax files listed on the command line,
129 as well as the default encoding for syntax files included with
130 INCLUDE or INSERT. The default is to accept the system locale
131 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
132 one the system file uses.
134 See the documentation for the INSERT command in the PSPP manual for
137 * A new Perl module allows Perl programs to read and write PSPP
140 * A tutorial chapter has been added to the user manual.
142 Changes from 0.6.1 to 0.6.2:
146 - Dutch, thanks to Harry Thijssen.
148 - Brazilian Portuguese, thanks to Michel Boaventura.
150 Thanks for translations are also due to the coordinators at
151 translationproject.org.
153 * Statistical bug fixes:
155 - REGRESSION: Report correct standard error of the estimate (bug
158 - T-TEST: Report correct significance of paired sample T-test in
159 the common case (bug #26936) and corner cases. Thanks to Mike
160 Griffiths and Matej Cepl for reporting these bugs.
162 * Build fixes and changes:
164 - Fix build with GTK+ 2.17.4 and later.
166 - Make running "make" after running "configure" with different
167 settings reliably rebuild version.c.
169 - Cygwin and MinGW build fixes.
171 - Fixes for building with recent gnulib.
173 - The Makefile now honors two new variables, PSPP_LDFLAGS and
174 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
175 binaries, respectively. This makes building easier for some
178 - Fixes for "configure --enable-relocatable" (bug #25508).
180 * Data file bug fixes and changes:
182 - Fix reading text data files that contain a mix of white space
183 and commas. Now "a ,b" is treated as two fields containing "a"
184 and "b"; previously it was treated as three, with an empty field
187 - Fix writing corrupted .sav files on Windows.
189 - Fix writing variable labels longer than 252 bytes to save files.
190 Thanks to Robert Westlund for reporting this bug.
192 - Fix writing corrupted .por files (bug #26034).
194 - Fix reading .por files whose initial lines are not padded out
195 with spaces as expected.
197 - PSPP will no longer issue warnings about some .sav file records
198 or values that it does not understand. These warnings were
199 harmless, but needlessly alarmed some users.
201 - Fix crash reading empty string fields from PostgreSQL databases.
203 * Bug fixes that affect PSPP and PSPPIRE:
205 - Users may now control precision of output statistics. Instead
206 of hard coding the width and decimals of output numbers, respect
207 the default format in most instances. Counts are now normally
208 displayed with the format of the weight variable, if any.
210 - Fix crash when an INSERT command specifies the name of a file
211 that does not exist (bug #24569).
213 - Fix crash when CROSSTABS specifies a long-string variable (bugs
216 - Fix crash drawing pie charts with many segments.
218 - Fix crash when NUMERIC specifies an invalid format.
220 * PSPPIRE bug fixes and changes:
222 - On Windows, write the output file to the user's home directory
223 instead of the current directory, to better match user
226 - Some data editor fixes.
230 - Fix typo in BINOMIAL section of user manual (bug #25892).
232 Changes from 0.6.0 to 0.6.1:
234 * Statistical bug fixes:
236 - Report correct standardized regression coefficients in linear
237 regression output (bug #23567).
239 * Bug fixes that affect PSPP and PSPPIRE:
241 - Avoid crash with pie charts (bug #24014).
243 - Don't append % to count totals (bug #24003).
245 - Don't crash on bad input (bug #24031).
247 - Don't crash if "end data." is not left aligned (bug #24115).
249 - Change default workspace value to 64 MB, to avoid unnecessary
250 disk accesses on modern machines.
254 - Add ".sav" or ".por" suffix to filename when saving with Save_As
257 - Make it possible to reopen the output window on Windows (bug
260 - A POSIX regular expression library is now included and used
261 automatically if the host does not have one or has one that is
264 * Build fixes and changes:
266 - Work around bug in GSL that prevented build with recent GCC
267 versions without manually adding -fgnu89-inline to CFLAGS.
269 - Also warn about missing prerequisites as we encounter them (bug
272 - Distribute necessary files to allow users working from the
273 distributed tarball to configure with --enable-gui-tools.
275 - Append $(EXEEXT_FOR_BUILD) to output file name when building
276 q2c, fixing build problems on Windows.
278 - GSL 1.8 or later is now required.
280 - Build errors with --enable-relocatable were fixed.
282 * The German translations were removed, since native German speakers
283 found them too poor to be useful.
285 Changes from 0.4.0 to 0.6.0:
287 * The PSPP license is now version 3 or later of the GNU General
288 Public License. Previously, it was version 2 or later.
290 * PSPP now has a graphical interface, called PSPPIRE. This
291 interface allows you to enter data and variable definitions
292 interactively. Commands may be executed in syntax form, or by
293 using the interactive dialog boxes available from the dropdown
296 * A few sample syntax files are now included in the `examples'
299 * Numerous major and minor bugs have been fixed.
303 * The INSTALL file now reflects the details of how to install
304 PSPP. It is a tailored version of the generic installation
305 instructions, instead of a verbatim copy.
307 * iconv, which is ordinarily installed as part of a Unix-like
308 system, is now required. If you don't have it already, you can
309 install GNU libiconv (http://www.gnu.org/software/libiconv/).
311 * libxml2 and zlib are new optional dependencies. They are
312 required to use PSPP's support for reading Gnumeric files.
314 Statistical procedure changes:
316 * REGRESSION is a new procedure for fitting linear models to data
317 via least-squares estimation.
319 * NPAR TESTS is a new procedure for non-parametric tests. In this
320 release, it supports binomial and chi-square tests.
322 * RANK is a new procedure to rank variables. It supports numerous
325 * FREQUENCIES can now output histograms and pie charts. These
326 features were present in earlier releases, but not documented.
328 User interface changes:
330 * In many situations where PSPP once terminated with a fatal
331 error, PSPP now recovers and continues execution.
333 * PSPP is now able to start up and run even if it cannot find its
336 * Journaling of interactive commands to a disk file is now
337 implemented. By default, journaling is enabled, to a file named
338 `pspp.jnl' in the current directory. SET JOURNAL may be used to
341 * The use of `+' between syntax file names on the command line to
342 prevent the dictionary from being cleared between their
343 executions is no longer supported. All syntax files are now
344 executed as if `+' had been specified.
346 * The -d/--define and -u/--undef command line options are no
347 longer supported. Instead, use /usr/bin/env or shell primitives
348 to define or clear environment variables before invoking PSPP.
350 * If a syntax file named named `rc' is found in a configuration
351 directory (such as $HOME/.pspp), it is executed before any
352 syntax file specified on the command line. The -r or
353 --no-statrc command line option may be used to disable this
358 * Output configuration options have changed. Please refer to the
359 manual for a full description of the available options.
361 In consequence, you will need to reinstall your "devices" file.
362 "make install" will do this for you.
364 * Most error messages are now written to PSPP output files by
365 default. SET ERROR can be used to disable this behavior.
367 * When invoked interactively, PSPP now by default produces output
368 on the terminal, piping it through the "more" program.
369 Previously, by default output was written only to file
370 pspp.list. On most terminals, the page length used for output
371 automatically adapts to the terminal size, even if the terminal
376 - This driver now supports charts in output. Charts are written
377 as separate files that the main output file refers to. By
378 default, charts are written in PNG format to files named
379 pspp-1.png, pspp-2.png, and so on.
381 - Configurations are provided that use VT100 (and xterm)
382 line-drawing characters in tables. The option "-o list-vt100"
383 requests use of this device for output to pspp.list.
387 - The default paper size is now determined using the PAPERSIZE
388 environment variable, or the LC_PAPER locale category on
389 systems that support it. If these are not set, the default is
390 now A4, instead of US letter. To make US letter the default,
391 set PAPERSIZE to "letter" in your environment.
393 - Font metrics are now read from AFM files, instead of
394 Groff-format metrics files. PostScript fonts can now be
397 In consequence, you will need to install an AFM file for each
398 font used in PostScript output. "make install" will install
399 AFM files for the standard PostScript fonts, including the
400 ones that the PostScript driver uses by default.
402 - Standard paper sizes no longer need to be specified through a
403 configuration file. The "papersize" configuration file is no
404 longer needed, or supported.
406 - The PostScript prologue is no longer obtained from the
407 "ps-prologue" configuration file. This configuration file is
408 no longer needed, or supported.
412 - The HTML prologue is no longer obtained from the
413 "html-prologue" configuration file. This configuration file
414 is no longer needed, or supported.
416 Command language changes:
418 * The following commands are new:
420 - GET DATA, which currently supports reading Gnumeric files and
421 text data files. It will be extended later to read other
422 types of foreign data.
424 - CD, to change the current directory.
426 - INSERT, to execute a syntax file.
428 - DELETE VARIABLES, to remove variables from the active file
431 - ADD DOCUMENT, to add text to active file documents.
433 - CLOSE FILE HANDLE (a PSPP extension; see below).
435 - XEXPORT, a PSPP extension that is a transformation equivalent
438 * The following functions for transformation expressions are new:
440 - DATEDIFF, for computing the difference of two dates.
442 - DATESUM, for advancing a date by a specified duration.
444 - VALUELABEL, to obtain the value label for a value.
446 * PSPP now supports very long string variables (over 255 bytes
449 * MATCH FILES now supports the FIRST and LAST subcommands.
451 * Previous versions of PSPP prohibited using commands to both read and
452 write a single file at the same time. Now, PSPP allows this, and
453 the new version of the file atomically replaces the old version.
455 * The following commands are no longer available. They will be
456 re-implemented in a later release:
458 - CLEAR TRANSFORMATIONS
464 * The PROCESS IF command, which was deprecated, has been removed.
465 You may replace any usage of it by SELECT IF following
466 TEMPORARY, which has the same effect.
468 * The output format for variables created by VECTOR may now be
469 specified as part of the VECTOR syntax.
471 "Scratch files", a new PSPP extension:
473 A scratch file, like a system file, consists of a dictionary and
474 any number of cases. Small scratch files are stored in memory;
475 one that grows too large is written to disk. By default, any file
476 handle whose name begins with # is assumed to refer to a scratch
479 Scratch files can be used just about anywhere a system or portable
480 file can be used. Also, portable files are now allowed in most
481 places that system files were allowed in previous PSPP version.
483 A new CLOSE FILE HANDLE command allows the storage associated with
484 scratch files to be freed. It also allows file handles to be
485 reassigned to new files.
487 For more information on scratch files, refer to the "File Handles"
488 section in the PSPP manual. For specifics of what commands now
489 allow what kinds of files to be specified, refer to the
490 documentation on those particular commands.
494 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
495 translation, are now supported. Use FILE HANDLE to specify the
496 format of these files.
498 * Little-endian, big-endian, and VAX-endian formats are now
499 supported for integer binary formats when reading and writing
500 data files. The new RIB and WIB subcommands on the SET command
501 control endianness of integer data. The default is the host's
504 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
505 floating point binary formats when reading and writing data
506 files. The new RRB and WRB subcommands on the SET command
507 control the floating point format. The default is the host's
508 native floating point format.
510 * DATA LIST now supports the SKIP subcommand, to skip records at
511 the beginning of a file. For compatibility, DATA LIST now
512 treats N format as F format for FREE and LIST format input.
514 * The SAVE and XSAVE commands now support the UNSELECTED,
515 PERMISSIONS, NAMES, and MAP subcommands.
517 * The EXPORT command has been re-implemented to obtain better
518 results. Support for the UNSELECTED, DIGITS, and TYPE
519 subcommands has been added.
521 * For compatibility, PRINT now inserts a space at the beginning of
522 every output line, even lines that would otherwise be blank,
523 when OUTFILE is specified. (The behavior of WRITE is
526 * For compatibility, PRINT EJECT now inserts the digit `1' at the
527 beginning of each line that should begin a new page.
529 * For compatibility, WRITE now outputs the system-missing value as
530 a field filled with spaces. Binary formats are an exception.
531 (The behavior of PRINT is unchanged.)
535 * Input and output format descriptions have been rewritten. They
536 now precisely describe what is accepted on input and written on
539 * The descriptions of the PSPP system and portable file formats
540 have been extensively revised and improved.
542 For developers, the build system now requires Autoconf 2.60 and
545 Changes from 0.3.0 to 0.4.0:
547 Changes in build dependencies:
549 * The GNU Scientific Library (libgsl), version 1.6 or later, is
552 * libplot from GNU plotutils is optional. Without it, the new
553 graphing features will not work. If you do not have it
554 installed, you must run `configure' with --without-libplot.
556 * libgmp2 is no longer a dependency.
558 Newly implemented commands and statistical features:
560 * EXAMINE, including its graphing features.
562 * FREQUENCIES now supports percentiles.
570 * SORT CASES now sorts stably, that is, two cases with equal sort
571 criteria will be in the same relative order before and after the
574 * T-TEST (re-written).
576 * DATE and USE. These commands are parsed but otherwise ignored,
577 to enhance compatibility with certain command files that invoke
580 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
581 currently have no effect on PSPP output, but their values are
582 written to and read from system files and thus may affect
583 third-party software.
585 * SET EPOCH implemented.
587 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
590 * FILE HANDLE now supports custom tab widths.
592 Long variable names (and other identifiers) are now supported. Up
593 to the first 64 bytes of each identifier is significant. PSPP now
594 reads and writes system files compatible with SPSS version 12.
596 New --algorithm and --syntax command line options allow
597 SPSS-compatible or enhanced modes to be selected.
599 Support for transformation expressions has been rewritten and
600 significantly improved. Refer to the manual for details.
602 Calculation of moments (mean, standard deviation, kurtosis,
603 skewness) has been rewritten and should now be more accurate. In
604 --algorithm=enhanced mode moments may be more accurate than SPSS in
607 Numerous bugs have been fixed, too many to mention here. Many new
608 tests have been added, leading to the discovery and fixing of many
611 The ASCII output driver can now squeeze multiple blank lines into
614 Much of the code has been rewritten and refactored. It is now much
617 The FILE TYPE and REPEATING DATA commands have been disabled for
618 this release because their implementations were deemed too buggy to
619 be useful. They will be fixed and replaced in a future release.
621 New pspp-mode for Emacs (in pspp-mode.el).
623 Added rudimentary command-line completion for interactive input.
625 lib/julcal and lib/dcdflib are no longer used, so they have been
628 For developers, the build system now requires Autoconf 2.58 and
629 Automake 1.7. The included gettext has been updated to version
632 Some reports state that Texinfo 4.8, the latest version, may be
633 necessary to successfully format the documentation on some systems.
635 Version 0.3.0 changes since 0.2.3:
639 * Using alphanumeric variables in functions under AGGREGATE
642 * Under certain circumstances, the final case would be omitted
643 from the results of an AGGREGATE operation. Fixed.
645 * Undefined behavior was invoked by referencing a freed pointer
646 under certain circumstances. Fixed.
648 * A wrong record size was displayed when paging the active file to
651 * Not having enough temporary space for sorting caused a core
654 * Syntax errors in function descriptions on AGGREGATE caused core
657 * A null pointer was dereferenced, causing a core dump, when
658 PERCENTILES was specified on FREQUENCIES. This fixes the
659 problem, but PSPP still doesn't calculate percentiles.
661 * SORT always sorted in ascending order. Fixed.
663 * Some minor memory leaks in the expression parser were removed.
665 * Many assertions fixed for strict ANSI C compliance.
669 * SET ECHO ON now implemented, but turned off by default.
671 * PRINT specifier supported on END REPEAT.
675 * System libgmp2 library is used if installed instead of
676 unconditionally using the included libgmp2 subset.
678 * Extensive code cleanup, which continues.
680 * Added CORRELATIONS command parser, but not implemented.
682 Version 0.2.3 changes since 0.2.2:
686 * SPLIT FILE with a string variable caused a core dump. Fixed.
688 * Nested INCLUDEs didn't work. Fixed.
690 * The MATCH FILES procedure set the values of variables not present
691 to 0. It should have been SYSMIS. This is now fixed.
693 * The REMARK command was too aggressive about skipping lines. It
694 didn't like being the last command in a file.
696 * Comment parsing wasn't consistent with the rest of the code in its
697 idea of where one command ends and another starts. This meant
698 that sometimes commands would be mysteriously ignored. Thanks to
699 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
701 * The TABLE subcommand on MATCH FILES worked only erratically at
702 best. This fixes it. Thanks to Dr. Dirk Melcher
703 <BZN-mdksh@t-online.de> for reporting this bug.
705 * VARIABLE LABELS rejected a slash before the first variable
706 specification, contradicting the documentation. Thanks to Walter
707 M. Gray <graywm@northernc.on.ca> for reporting this bug.
709 * Because of an incorrect optimization in memory allocation,
710 CROSSTABS sometimes segfaulted when asked to output multiple
711 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
714 * CROSSTABS didn't display value labels for column and row
715 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
718 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
719 <BZN-mdksh@t-online.de> for reporting this bug.
721 * The TABLE subcommand on MATCH FILES worked only erratically at
722 best. This fixes it. Thanks to Dr. Dirk Melcher
723 <BZN-mdksh@t-online.de> for reporting this bug.
725 * VARIABLE LABELS rejected a slash before the first variable
726 specification, contradicting the documentation. Thanks to Walter
727 M. Gray <graywm@northernc.on.ca> for reporting this bug.
729 * Because of an incorrect optimization in memory allocation,
730 CROSSTABS sometimes segfaulted when asked to output multiple
731 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
734 * CROSSTABS didn't display value labels for column and row
735 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
738 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
739 <BZN-mdksh@t-online.de> for reporting this bug.
741 * MATCH FILES corrupted memory and dumped core on some syntax
744 * MATCH FILES should set numeric values not available to the
745 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
746 <BZN-mdksh@t-online.de> for reporting this bug.
748 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
749 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
753 * Some systems didn't like the way open_file was coded. Thanks to
754 Hankin <hankin@rogue.consultco.com> for pointing this out.
756 * The SAVE procedure didn't save long string variables properly.
757 Fixed by this patch. Thanks to Hankin
758 <hankin@rogue.consultco.com> for this patch.
760 * Minor documentation fixes for MATCH FILES.
762 Version 0.2.2 changes since 0.2.1:
766 * Fix behavior of PRINT SPACE for negative arguments.
768 * Fix reading some unusual system files.
770 * Fix LIST problems with very long variables. Thanks to Hankin
771 <hankin@dunno.com> for this bug report.
773 * Fix problems with some string format specifiers.
775 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
776 <BZN-mdksh@t-online.de> for reporting this bug.
778 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
779 Hankin <hankin@dunno.com> again on this one.
781 * Sometimes you may encounter a PSPP script that has to be
782 interpreted in interactive mode. Now you can use the -i flag to
785 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
786 `unused variable' warnings under gcc 2.7.2.3, fixing this will
791 * The files in gmp need the internationalization directory in
792 their include path. Thanks to OKUJI Yoshinori
793 <okuji@kuicr.kyoto-u.ac.jp> for pointing this out.
795 Version 0.2.1 changes since 0.2.0:
799 * Remember to include examples/ directory in distribution :-)
