5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
7 Changes from 0.8.1 to 0.8.1.1:
9 * Charts are now rendered with colours from the Tango palette instead
10 of fully saturated primaries.
12 * Support for new system file variants:
14 - PSPP can now read and write ZCOMPRESSED system files, which
15 compress data much more effectively than older "compressed"
16 files. (The older format is still supported.)
18 - PSPP can now decrypt encrypted system files, using the new
19 pspp-convert utility. The encrypted system file format is
20 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
21 do not directly read or write this format.
23 * Missing values for long string variables are now read from and
24 written to system files in an SPSS-compatible fashion.
26 (Earlier versions of PSPP that supported missing values for long
27 string variables wrote them to system files in an SPSS-incompatible
28 way. To fix the problem, read the system file with this version of
29 PSPP and then save a new copy of it.)
31 * pspp-convert, a new standalone utility for converting SPSS system
32 and portable files to other formats, is now included. The initial
33 version supports comma-separated value files as output format.
34 pspp-convert can also decrypt encrypted system files.
38 - zlib is now a required dependency. (Previously it was optional.)
40 Changes from 0.8.0 to 0.8.1:
46 * Changes to existing commands:
48 - CROSSTABS: The requirement that one expected count must be less than five
49 before Fishers Exact Test will be reported has been removed.
51 * PSPPIRE graphical user interface improvements:
53 - A new set of icons has been contributed.
55 - Syntax windows now parse syntax in "auto" mode, which in practice
56 should mean that both "batch" and "interactive" syntax now works,
57 instead of just "interactive" syntax.
59 - The variable pane of data windows now include a Role column.
63 - System files written by IBM SPSS 21 are now read without warnings.
65 - System files written by "VOXCO INTERVIEWER 4.3" are now read
68 - PSPPIRE should now more gracefully handle syntax files that contain
71 Changes from 0.6.2 to 0.8.0:
88 - PRESERVE and RESTORE
92 - SAVE TRANSLATE to CSV and tab-delimited files
96 * Changes to existing commands:
98 - AUTORECODE has a new GROUP subcommand.
100 - CROSSTABS has been re-implemented to fix numerous bugs.
102 - EXAMINE: /MISSING=LISTWISE is now the default.
104 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
105 contains an INCLUDE or INSERT command, substitutions are not
106 applied to the included file.
108 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
110 - HOST has been updated to use more modern syntax.
112 - Most commands that work with data files now support a new
115 - MISSING VALUES can now assign missing values to long string
118 - ONEWAY: the POSTHOC subcommand is now implemented.
120 - The following new subcommands to NPAR TESTS have been implemented:
121 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
122 MCNEMAR, SIGN, WILCOXON, and RUNS
124 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
125 DPROMPT subcommands. The defaults are now fixed values.
127 - SHOW now has a JOURNAL subcommand, to show the location of the
130 - VALUE LABELS can now assign value labels to long string
133 * Other language changes:
135 - The new DATASET commands replace the "scratch file" PSPP
136 extension, which is no longer supported.
138 - Strings may now include arbitrary Unicode code points specified
139 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
140 code point U+1D11E, the musical G clef character, may be
141 expressed as U'1D11E'.
143 See the "Tokens" section in the PSPP manual for more information.
145 - In previous versions of PSPP, in a string expressed in
146 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
147 bytes in the locale encoding. In this version of PSPP, X'hh'
148 syntax always expresses bytes in UTF-8 encoding.
150 See the "Tokens" section in the PSPP manual for more information.
152 * PSPPIRE graphical user interface improvements:
154 - Added support for non-ASCII characters in strings, labels and
157 - A "Split Window" function is available, which makes it easier to
158 see different parts of a large data file.
160 - Data files can now be opened by specifing their name as the first
161 argument. This means that on a properly configured desktop, double
162 clicking on an icon will open the file.
164 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
165 via using an "intelligent" application assistant dialog.
169 - The new "cairo" output driver supports output in PostScript, PDF,
170 and SVG formats. Its functionality is a superset of that of the
171 "postscript" driver, which has been removed. You must have Cairo
172 and Pango installed to build the "cairo" driver.
174 - Charts are now produced with Cairo and Pango, instead of libplot.
175 Without them, the new graphing features will not work. If you do
176 not have Cairo and Pango installed, you must run `configure' with
179 - The plain text output driver now properly supports multibyte UTF-8
180 characters, including double-width characters and combining
183 - Output to OpenDocument format is now supported.
185 - The HTML output is much improved.
187 * The "pspp" program has a new option --batch (or -b) that selects
188 "batch" syntax mode. In previous versions of PSPP this syntax mode
189 was the default. Now a new "auto" syntax mode is the default. In
190 "auto" mode, PSPP interprets most syntax files correctly regardless
191 of their intended syntax mode.
193 See the "Syntax Variants" section in the PSPP manual for more
196 * The "pspp" program has a new option --syntax-encoding that
197 specifies the encoding for syntax files listed on the command line,
198 as well as the default encoding for syntax files included with
199 INCLUDE or INSERT. The default is to accept the system locale
200 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
201 one the system file uses.
203 See the documentation for the INSERT command in the PSPP manual for
206 * Text data files that PRINT and WRITE creates now use the system
207 native line ends by default (CRLF on Windows, LF only elsewhere).
208 Use the new ENDS subcommand on FILE HANDLE to override the default.
210 * A new Perl module allows Perl programs to read and write PSPP
213 * A tutorial chapter has been added to the user manual.
215 Changes from 0.6.1 to 0.6.2:
219 - Dutch, thanks to Harry Thijssen.
221 - Brazilian Portuguese, thanks to Michel Boaventura.
223 Thanks for translations are also due to the coordinators at
224 translationproject.org.
226 * Statistical bug fixes:
228 - REGRESSION: Report correct standard error of the estimate (bug
231 - T-TEST: Report correct significance of paired sample T-test in
232 the common case (bug #26936) and corner cases. Thanks to Mike
233 Griffiths and Matej Cepl for reporting these bugs.
235 * Build fixes and changes:
237 - Fix build with GTK+ 2.17.4 and later.
239 - Make running "make" after running "configure" with different
240 settings reliably rebuild version.c.
242 - Cygwin and MinGW build fixes.
244 - Fixes for building with recent gnulib.
246 - The Makefile now honors two new variables, PSPP_LDFLAGS and
247 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
248 binaries, respectively. This makes building easier for some
251 - Fixes for "configure --enable-relocatable" (bug #25508).
253 * Data file bug fixes and changes:
255 - Fix reading text data files that contain a mix of white space
256 and commas. Now "a ,b" is treated as two fields containing "a"
257 and "b"; previously it was treated as three, with an empty field
260 - Fix writing corrupted .sav files on Windows.
262 - Fix writing variable labels longer than 252 bytes to save files.
263 Thanks to Robert Westlund for reporting this bug.
265 - Fix writing corrupted .por files (bug #26034).
267 - Fix reading .por files whose initial lines are not padded out
268 with spaces as expected.
270 - PSPP will no longer issue warnings about some .sav file records
271 or values that it does not understand. These warnings were
272 harmless, but needlessly alarmed some users.
274 - Fix crash reading empty string fields from PostgreSQL databases.
276 * Bug fixes that affect PSPP and PSPPIRE:
278 - Users may now control precision of output statistics. Instead
279 of hard coding the width and decimals of output numbers, respect
280 the default format in most instances. Counts are now normally
281 displayed with the format of the weight variable, if any.
283 - Fix crash when an INSERT command specifies the name of a file
284 that does not exist (bug #24569).
286 - Fix crash when CROSSTABS specifies a long-string variable (bugs
289 - Fix crash drawing pie charts with many segments.
291 - Fix crash when NUMERIC specifies an invalid format.
293 * PSPPIRE bug fixes and changes:
295 - On Windows, write the output file to the user's home directory
296 instead of the current directory, to better match user
299 - Some data editor fixes.
303 - Fix typo in BINOMIAL section of user manual (bug #25892).
305 Changes from 0.6.0 to 0.6.1:
307 * Statistical bug fixes:
309 - Report correct standardized regression coefficients in linear
310 regression output (bug #23567).
312 * Bug fixes that affect PSPP and PSPPIRE:
314 - Avoid crash with pie charts (bug #24014).
316 - Don't append % to count totals (bug #24003).
318 - Don't crash on bad input (bug #24031).
320 - Don't crash if "end data." is not left aligned (bug #24115).
322 - Change default workspace value to 64 MB, to avoid unnecessary
323 disk accesses on modern machines.
327 - Add ".sav" or ".por" suffix to filename when saving with Save_As
330 - Make it possible to reopen the output window on Windows (bug
333 - A POSIX regular expression library is now included and used
334 automatically if the host does not have one or has one that is
337 * Build fixes and changes:
339 - Work around bug in GSL that prevented build with recent GCC
340 versions without manually adding -fgnu89-inline to CFLAGS.
342 - Also warn about missing prerequisites as we encounter them (bug
345 - Distribute necessary files to allow users working from the
346 distributed tarball to configure with --enable-gui-tools.
348 - Append $(EXEEXT_FOR_BUILD) to output file name when building
349 q2c, fixing build problems on Windows.
351 - GSL 1.8 or later is now required.
353 - Build errors with --enable-relocatable were fixed.
355 * The German translations were removed, since native German speakers
356 found them too poor to be useful.
358 Changes from 0.4.0 to 0.6.0:
360 * The PSPP license is now version 3 or later of the GNU General
361 Public License. Previously, it was version 2 or later.
363 * PSPP now has a graphical interface, called PSPPIRE. This
364 interface allows you to enter data and variable definitions
365 interactively. Commands may be executed in syntax form, or by
366 using the interactive dialog boxes available from the dropdown
369 * A few sample syntax files are now included in the `examples'
372 * Numerous major and minor bugs have been fixed.
376 * The INSTALL file now reflects the details of how to install
377 PSPP. It is a tailored version of the generic installation
378 instructions, instead of a verbatim copy.
380 * iconv, which is ordinarily installed as part of a Unix-like
381 system, is now required. If you don't have it already, you can
382 install GNU libiconv (http://www.gnu.org/software/libiconv/).
384 * libxml2 and zlib are new optional dependencies. They are
385 required to use PSPP's support for reading Gnumeric files.
387 Statistical procedure changes:
389 * REGRESSION is a new procedure for fitting linear models to data
390 via least-squares estimation.
392 * NPAR TESTS is a new procedure for non-parametric tests. In this
393 release, it supports binomial and chi-square tests.
395 * RANK is a new procedure to rank variables. It supports numerous
398 * FREQUENCIES can now output histograms and pie charts. These
399 features were present in earlier releases, but not documented.
401 User interface changes:
403 * In many situations where PSPP once terminated with a fatal
404 error, PSPP now recovers and continues execution.
406 * PSPP is now able to start up and run even if it cannot find its
409 * Journaling of interactive commands to a disk file is now
410 implemented. By default, journaling is enabled, to a file named
411 `pspp.jnl' in the current directory. SET JOURNAL may be used to
414 * The use of `+' between syntax file names on the command line to
415 prevent the dictionary from being cleared between their
416 executions is no longer supported. All syntax files are now
417 executed as if `+' had been specified.
419 * The -d/--define and -u/--undef command line options are no
420 longer supported. Instead, use /usr/bin/env or shell primitives
421 to define or clear environment variables before invoking PSPP.
423 * If a syntax file named named `rc' is found in a configuration
424 directory (such as $HOME/.pspp), it is executed before any
425 syntax file specified on the command line. The -r or
426 --no-statrc command line option may be used to disable this
431 * Output configuration options have changed. Please refer to the
432 manual for a full description of the available options.
434 In consequence, you will need to reinstall your "devices" file.
435 "make install" will do this for you.
437 * Most error messages are now written to PSPP output files by
438 default. SET ERROR can be used to disable this behavior.
440 * When invoked interactively, PSPP now by default produces output
441 on the terminal, piping it through the "more" program.
442 Previously, by default output was written only to file
443 pspp.list. On most terminals, the page length used for output
444 automatically adapts to the terminal size, even if the terminal
449 - This driver now supports charts in output. Charts are written
450 as separate files that the main output file refers to. By
451 default, charts are written in PNG format to files named
452 pspp-1.png, pspp-2.png, and so on.
454 - Configurations are provided that use VT100 (and xterm)
455 line-drawing characters in tables. The option "-o list-vt100"
456 requests use of this device for output to pspp.list.
460 - The default paper size is now determined using the PAPERSIZE
461 environment variable, or the LC_PAPER locale category on
462 systems that support it. If these are not set, the default is
463 now A4, instead of US letter. To make US letter the default,
464 set PAPERSIZE to "letter" in your environment.
466 - Font metrics are now read from AFM files, instead of
467 Groff-format metrics files. PostScript fonts can now be
470 In consequence, you will need to install an AFM file for each
471 font used in PostScript output. "make install" will install
472 AFM files for the standard PostScript fonts, including the
473 ones that the PostScript driver uses by default.
475 - Standard paper sizes no longer need to be specified through a
476 configuration file. The "papersize" configuration file is no
477 longer needed, or supported.
479 - The PostScript prologue is no longer obtained from the
480 "ps-prologue" configuration file. This configuration file is
481 no longer needed, or supported.
485 - The HTML prologue is no longer obtained from the
486 "html-prologue" configuration file. This configuration file
487 is no longer needed, or supported.
489 Command language changes:
491 * The following commands are new:
493 - GET DATA, which currently supports reading Gnumeric files and
494 text data files. It will be extended later to read other
495 types of foreign data.
497 - CD, to change the current directory.
499 - INSERT, to execute a syntax file.
501 - DELETE VARIABLES, to remove variables from the active file
504 - ADD DOCUMENT, to add text to active file documents.
506 - CLOSE FILE HANDLE (a PSPP extension; see below).
508 - XEXPORT, a PSPP extension that is a transformation equivalent
511 * The following functions for transformation expressions are new:
513 - DATEDIFF, for computing the difference of two dates.
515 - DATESUM, for advancing a date by a specified duration.
517 - VALUELABEL, to obtain the value label for a value.
519 * PSPP now supports very long string variables (over 255 bytes
522 * MATCH FILES now supports the FIRST and LAST subcommands.
524 * Previous versions of PSPP prohibited using commands to both read and
525 write a single file at the same time. Now, PSPP allows this, and
526 the new version of the file atomically replaces the old version.
528 * The following commands are no longer available. They will be
529 re-implemented in a later release:
531 - CLEAR TRANSFORMATIONS
537 * The PROCESS IF command, which was deprecated, has been removed.
538 You may replace any usage of it by SELECT IF following
539 TEMPORARY, which has the same effect.
541 * The output format for variables created by VECTOR may now be
542 specified as part of the VECTOR syntax.
544 "Scratch files", a new PSPP extension:
546 A scratch file, like a system file, consists of a dictionary and
547 any number of cases. Small scratch files are stored in memory;
548 one that grows too large is written to disk. By default, any file
549 handle whose name begins with # is assumed to refer to a scratch
552 Scratch files can be used just about anywhere a system or portable
553 file can be used. Also, portable files are now allowed in most
554 places that system files were allowed in previous PSPP version.
556 A new CLOSE FILE HANDLE command allows the storage associated with
557 scratch files to be freed. It also allows file handles to be
558 reassigned to new files.
560 For more information on scratch files, refer to the "File Handles"
561 section in the PSPP manual. For specifics of what commands now
562 allow what kinds of files to be specified, refer to the
563 documentation on those particular commands.
567 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
568 translation, are now supported. Use FILE HANDLE to specify the
569 format of these files.
571 * Little-endian, big-endian, and VAX-endian formats are now
572 supported for integer binary formats when reading and writing
573 data files. The new RIB and WIB subcommands on the SET command
574 control endianness of integer data. The default is the host's
577 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
578 floating point binary formats when reading and writing data
579 files. The new RRB and WRB subcommands on the SET command
580 control the floating point format. The default is the host's
581 native floating point format.
583 * DATA LIST now supports the SKIP subcommand, to skip records at
584 the beginning of a file. For compatibility, DATA LIST now
585 treats N format as F format for FREE and LIST format input.
587 * The SAVE and XSAVE commands now support the UNSELECTED,
588 PERMISSIONS, NAMES, and MAP subcommands.
590 * The EXPORT command has been re-implemented to obtain better
591 results. Support for the UNSELECTED, DIGITS, and TYPE
592 subcommands has been added.
594 * For compatibility, PRINT now inserts a space at the beginning of
595 every output line, even lines that would otherwise be blank,
596 when OUTFILE is specified. (The behavior of WRITE is
599 * For compatibility, PRINT EJECT now inserts the digit `1' at the
600 beginning of each line that should begin a new page.
602 * For compatibility, WRITE now outputs the system-missing value as
603 a field filled with spaces. Binary formats are an exception.
604 (The behavior of PRINT is unchanged.)
608 * Input and output format descriptions have been rewritten. They
609 now precisely describe what is accepted on input and written on
612 * The descriptions of the PSPP system and portable file formats
613 have been extensively revised and improved.
615 For developers, the build system now requires Autoconf 2.60 and
618 Changes from 0.3.0 to 0.4.0:
620 Changes in build dependencies:
622 * The GNU Scientific Library (libgsl), version 1.6 or later, is
625 * libplot from GNU plotutils is optional. Without it, the new
626 graphing features will not work. If you do not have it
627 installed, you must run `configure' with --without-libplot.
629 * libgmp2 is no longer a dependency.
631 Newly implemented commands and statistical features:
633 * EXAMINE, including its graphing features.
635 * FREQUENCIES now supports percentiles.
643 * SORT CASES now sorts stably, that is, two cases with equal sort
644 criteria will be in the same relative order before and after the
647 * T-TEST (re-written).
649 * DATE and USE. These commands are parsed but otherwise ignored,
650 to enhance compatibility with certain command files that invoke
653 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
654 currently have no effect on PSPP output, but their values are
655 written to and read from system files and thus may affect
656 third-party software.
658 * SET EPOCH implemented.
660 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
663 * FILE HANDLE now supports custom tab widths.
665 Long variable names (and other identifiers) are now supported. Up
666 to the first 64 bytes of each identifier is significant. PSPP now
667 reads and writes system files compatible with SPSS version 12.
669 New --algorithm and --syntax command line options allow
670 SPSS-compatible or enhanced modes to be selected.
672 Support for transformation expressions has been rewritten and
673 significantly improved. Refer to the manual for details.
675 Calculation of moments (mean, standard deviation, kurtosis,
676 skewness) has been rewritten and should now be more accurate. In
677 --algorithm=enhanced mode moments may be more accurate than SPSS in
680 Numerous bugs have been fixed, too many to mention here. Many new
681 tests have been added, leading to the discovery and fixing of many
684 The ASCII output driver can now squeeze multiple blank lines into
687 Much of the code has been rewritten and refactored. It is now much
690 The FILE TYPE and REPEATING DATA commands have been disabled for
691 this release because their implementations were deemed too buggy to
692 be useful. They will be fixed and replaced in a future release.
694 New pspp-mode for Emacs (in pspp-mode.el).
696 Added rudimentary command-line completion for interactive input.
698 lib/julcal and lib/dcdflib are no longer used, so they have been
701 For developers, the build system now requires Autoconf 2.58 and
702 Automake 1.7. The included gettext has been updated to version
705 Some reports state that Texinfo 4.8, the latest version, may be
706 necessary to successfully format the documentation on some systems.
708 Version 0.3.0 changes since 0.2.3:
712 * Using alphanumeric variables in functions under AGGREGATE
715 * Under certain circumstances, the final case would be omitted
716 from the results of an AGGREGATE operation. Fixed.
718 * Undefined behavior was invoked by referencing a freed pointer
719 under certain circumstances. Fixed.
721 * A wrong record size was displayed when paging the active file to
724 * Not having enough temporary space for sorting caused a core
727 * Syntax errors in function descriptions on AGGREGATE caused core
730 * A null pointer was dereferenced, causing a core dump, when
731 PERCENTILES was specified on FREQUENCIES. This fixes the
732 problem, but PSPP still doesn't calculate percentiles.
734 * SORT always sorted in ascending order. Fixed.
736 * Some minor memory leaks in the expression parser were removed.
738 * Many assertions fixed for strict ANSI C compliance.
742 * SET ECHO ON now implemented, but turned off by default.
744 * PRINT specifier supported on END REPEAT.
748 * System libgmp2 library is used if installed instead of
749 unconditionally using the included libgmp2 subset.
751 * Extensive code cleanup, which continues.
753 * Added CORRELATIONS command parser, but not implemented.
755 Version 0.2.3 changes since 0.2.2:
759 * SPLIT FILE with a string variable caused a core dump. Fixed.
761 * Nested INCLUDEs didn't work. Fixed.
763 * The MATCH FILES procedure set the values of variables not present
764 to 0. It should have been SYSMIS. This is now fixed.
766 * The REMARK command was too aggressive about skipping lines. It
767 didn't like being the last command in a file.
769 * Comment parsing wasn't consistent with the rest of the code in its
770 idea of where one command ends and another starts. This meant
771 that sometimes commands would be mysteriously ignored. Thanks to
772 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
774 * The TABLE subcommand on MATCH FILES worked only erratically at
775 best. This fixes it. Thanks to Dr. Dirk Melcher
776 <BZN-mdksh@t-online.de> for reporting this bug.
778 * VARIABLE LABELS rejected a slash before the first variable
779 specification, contradicting the documentation. Thanks to Walter
780 M. Gray <graywm@northernc.on.ca> for reporting this bug.
782 * Because of an incorrect optimization in memory allocation,
783 CROSSTABS sometimes segfaulted when asked to output multiple
784 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
787 * CROSSTABS didn't display value labels for column and row
788 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
791 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
792 <BZN-mdksh@t-online.de> for reporting this bug.
794 * The TABLE subcommand on MATCH FILES worked only erratically at
795 best. This fixes it. Thanks to Dr. Dirk Melcher
796 <BZN-mdksh@t-online.de> for reporting this bug.
798 * VARIABLE LABELS rejected a slash before the first variable
799 specification, contradicting the documentation. Thanks to Walter
800 M. Gray <graywm@northernc.on.ca> for reporting this bug.
802 * Because of an incorrect optimization in memory allocation,
