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 * PSPPIRE graphical user interface improvements:
17 - File|Open now allows an encoding to be selected for opening
20 - File|Display Data File Information|External File... now allows an
21 encoding to be selected.
23 Changes from 0.8.1 to 0.8.2:
25 * Charts are now rendered with colours from the Tango palette instead
26 of fully saturated primaries.
28 * Support for new system file variants:
30 - PSPP can now read and write ZCOMPRESSED system files, which
31 compress data much more effectively than older "compressed"
32 files. (The older format is still supported.)
34 - PSPP can now decrypt encrypted system files, using the new
35 pspp-convert utility. The encrypted system file format is
36 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
37 do not directly read or write this format.
39 * Missing values for long string variables are now read from and
40 written to system files in an SPSS-compatible fashion.
42 (Earlier versions of PSPP that supported missing values for long
43 string variables wrote them to system files in an SPSS-incompatible
44 way. To fix the problem, read the system file with this version of
45 PSPP and then save a new copy of it.)
47 * pspp-convert, a new standalone utility for converting SPSS system
48 and portable files to other formats, is now included. The initial
49 version supports comma-separated value files as output format.
50 pspp-convert can also decrypt encrypted system files.
54 - zlib is now a required dependency. (Previously it was optional.)
56 Changes from 0.8.0 to 0.8.1:
62 * Changes to existing commands:
64 - CROSSTABS: The requirement that one expected count must be less than five
65 before Fishers Exact Test will be reported has been removed.
67 * PSPPIRE graphical user interface improvements:
69 - A new set of icons has been contributed.
71 - Syntax windows now parse syntax in "auto" mode, which in practice
72 should mean that both "batch" and "interactive" syntax now works,
73 instead of just "interactive" syntax.
75 - The variable pane of data windows now include a Role column.
79 - System files written by IBM SPSS 21 are now read without warnings.
81 - System files written by "VOXCO INTERVIEWER 4.3" are now read
84 - PSPPIRE should now more gracefully handle syntax files that contain
87 Changes from 0.6.2 to 0.8.0:
100 - LOGISTIC REGRESSION
104 - PRESERVE and RESTORE
108 - SAVE TRANSLATE to CSV and tab-delimited files
110 - VARIABLE ATTRIBUTES
112 * Changes to existing commands:
114 - AUTORECODE has a new GROUP subcommand.
116 - CROSSTABS has been re-implemented to fix numerous bugs.
118 - EXAMINE: /MISSING=LISTWISE is now the default.
120 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
121 contains an INCLUDE or INSERT command, substitutions are not
122 applied to the included file.
124 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
126 - HOST has been updated to use more modern syntax.
128 - Most commands that work with data files now support a new
131 - MISSING VALUES can now assign missing values to long string
134 - ONEWAY: the POSTHOC subcommand is now implemented.
136 - The following new subcommands to NPAR TESTS have been implemented:
137 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
138 MCNEMAR, SIGN, WILCOXON, and RUNS
140 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
141 DPROMPT subcommands. The defaults are now fixed values.
143 - SHOW now has a JOURNAL subcommand, to show the location of the
146 - VALUE LABELS can now assign value labels to long string
149 * Other language changes:
151 - The new DATASET commands replace the "scratch file" PSPP
152 extension, which is no longer supported.
154 - Strings may now include arbitrary Unicode code points specified
155 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
156 code point U+1D11E, the musical G clef character, may be
157 expressed as U'1D11E'.
159 See the "Tokens" section in the PSPP manual for more information.
161 - In previous versions of PSPP, in a string expressed in
162 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
163 bytes in the locale encoding. In this version of PSPP, X'hh'
164 syntax always expresses bytes in UTF-8 encoding.
166 See the "Tokens" section in the PSPP manual for more information.
168 * PSPPIRE graphical user interface improvements:
170 - Added support for non-ASCII characters in strings, labels and
173 - A "Split Window" function is available, which makes it easier to
174 see different parts of a large data file.
176 - Data files can now be opened by specifing their name as the first
177 argument. This means that on a properly configured desktop, double
178 clicking on an icon will open the file.
180 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
181 via using an "intelligent" application assistant dialog.
185 - The new "cairo" output driver supports output in PostScript, PDF,
186 and SVG formats. Its functionality is a superset of that of the
187 "postscript" driver, which has been removed. You must have Cairo
188 and Pango installed to build the "cairo" driver.
190 - Charts are now produced with Cairo and Pango, instead of libplot.
191 Without them, the new graphing features will not work. If you do
192 not have Cairo and Pango installed, you must run `configure' with
195 - The plain text output driver now properly supports multibyte UTF-8
196 characters, including double-width characters and combining
199 - Output to OpenDocument format is now supported.
201 - The HTML output is much improved.
203 * The "pspp" program has a new option --batch (or -b) that selects
204 "batch" syntax mode. In previous versions of PSPP this syntax mode
205 was the default. Now a new "auto" syntax mode is the default. In
206 "auto" mode, PSPP interprets most syntax files correctly regardless
207 of their intended syntax mode.
209 See the "Syntax Variants" section in the PSPP manual for more
212 * The "pspp" program has a new option --syntax-encoding that
213 specifies the encoding for syntax files listed on the command line,
214 as well as the default encoding for syntax files included with
215 INCLUDE or INSERT. The default is to accept the system locale
216 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
217 one the system file uses.
219 See the documentation for the INSERT command in the PSPP manual for
222 * Text data files that PRINT and WRITE creates now use the system
223 native line ends by default (CRLF on Windows, LF only elsewhere).
224 Use the new ENDS subcommand on FILE HANDLE to override the default.
226 * A new Perl module allows Perl programs to read and write PSPP
229 * A tutorial chapter has been added to the user manual.
231 Changes from 0.6.1 to 0.6.2:
235 - Dutch, thanks to Harry Thijssen.
237 - Brazilian Portuguese, thanks to Michel Boaventura.
239 Thanks for translations are also due to the coordinators at
240 translationproject.org.
242 * Statistical bug fixes:
244 - REGRESSION: Report correct standard error of the estimate (bug
247 - T-TEST: Report correct significance of paired sample T-test in
248 the common case (bug #26936) and corner cases. Thanks to Mike
249 Griffiths and Matej Cepl for reporting these bugs.
251 * Build fixes and changes:
253 - Fix build with GTK+ 2.17.4 and later.
255 - Make running "make" after running "configure" with different
256 settings reliably rebuild version.c.
258 - Cygwin and MinGW build fixes.
260 - Fixes for building with recent gnulib.
262 - The Makefile now honors two new variables, PSPP_LDFLAGS and
263 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
264 binaries, respectively. This makes building easier for some
267 - Fixes for "configure --enable-relocatable" (bug #25508).
269 * Data file bug fixes and changes:
271 - Fix reading text data files that contain a mix of white space
272 and commas. Now "a ,b" is treated as two fields containing "a"
273 and "b"; previously it was treated as three, with an empty field
276 - Fix writing corrupted .sav files on Windows.
278 - Fix writing variable labels longer than 252 bytes to save files.
279 Thanks to Robert Westlund for reporting this bug.
281 - Fix writing corrupted .por files (bug #26034).
283 - Fix reading .por files whose initial lines are not padded out
284 with spaces as expected.
286 - PSPP will no longer issue warnings about some .sav file records
287 or values that it does not understand. These warnings were
288 harmless, but needlessly alarmed some users.
290 - Fix crash reading empty string fields from PostgreSQL databases.
292 * Bug fixes that affect PSPP and PSPPIRE:
294 - Users may now control precision of output statistics. Instead
295 of hard coding the width and decimals of output numbers, respect
296 the default format in most instances. Counts are now normally
297 displayed with the format of the weight variable, if any.
299 - Fix crash when an INSERT command specifies the name of a file
300 that does not exist (bug #24569).
302 - Fix crash when CROSSTABS specifies a long-string variable (bugs
305 - Fix crash drawing pie charts with many segments.
307 - Fix crash when NUMERIC specifies an invalid format.
309 * PSPPIRE bug fixes and changes:
311 - On Windows, write the output file to the user's home directory
312 instead of the current directory, to better match user
315 - Some data editor fixes.
319 - Fix typo in BINOMIAL section of user manual (bug #25892).
321 Changes from 0.6.0 to 0.6.1:
323 * Statistical bug fixes:
325 - Report correct standardized regression coefficients in linear
326 regression output (bug #23567).
328 * Bug fixes that affect PSPP and PSPPIRE:
330 - Avoid crash with pie charts (bug #24014).
332 - Don't append % to count totals (bug #24003).
334 - Don't crash on bad input (bug #24031).
336 - Don't crash if "end data." is not left aligned (bug #24115).
338 - Change default workspace value to 64 MB, to avoid unnecessary
339 disk accesses on modern machines.
343 - Add ".sav" or ".por" suffix to filename when saving with Save_As
346 - Make it possible to reopen the output window on Windows (bug
349 - A POSIX regular expression library is now included and used
350 automatically if the host does not have one or has one that is
353 * Build fixes and changes:
355 - Work around bug in GSL that prevented build with recent GCC
356 versions without manually adding -fgnu89-inline to CFLAGS.
358 - Also warn about missing prerequisites as we encounter them (bug
361 - Distribute necessary files to allow users working from the
362 distributed tarball to configure with --enable-gui-tools.
364 - Append $(EXEEXT_FOR_BUILD) to output file name when building
365 q2c, fixing build problems on Windows.
367 - GSL 1.8 or later is now required.
369 - Build errors with --enable-relocatable were fixed.
371 * The German translations were removed, since native German speakers
372 found them too poor to be useful.
374 Changes from 0.4.0 to 0.6.0:
376 * The PSPP license is now version 3 or later of the GNU General
377 Public License. Previously, it was version 2 or later.
379 * PSPP now has a graphical interface, called PSPPIRE. This
380 interface allows you to enter data and variable definitions
381 interactively. Commands may be executed in syntax form, or by
382 using the interactive dialog boxes available from the dropdown
385 * A few sample syntax files are now included in the `examples'
388 * Numerous major and minor bugs have been fixed.
392 * The INSTALL file now reflects the details of how to install
393 PSPP. It is a tailored version of the generic installation
394 instructions, instead of a verbatim copy.
396 * iconv, which is ordinarily installed as part of a Unix-like
397 system, is now required. If you don't have it already, you can
398 install GNU libiconv (http://www.gnu.org/software/libiconv/).
400 * libxml2 and zlib are new optional dependencies. They are
401 required to use PSPP's support for reading Gnumeric files.
403 Statistical procedure changes:
405 * REGRESSION is a new procedure for fitting linear models to data
406 via least-squares estimation.
408 * NPAR TESTS is a new procedure for non-parametric tests. In this
409 release, it supports binomial and chi-square tests.
411 * RANK is a new procedure to rank variables. It supports numerous
414 * FREQUENCIES can now output histograms and pie charts. These
415 features were present in earlier releases, but not documented.
417 User interface changes:
419 * In many situations where PSPP once terminated with a fatal
420 error, PSPP now recovers and continues execution.
422 * PSPP is now able to start up and run even if it cannot find its
425 * Journaling of interactive commands to a disk file is now
426 implemented. By default, journaling is enabled, to a file named
427 `pspp.jnl' in the current directory. SET JOURNAL may be used to
430 * The use of `+' between syntax file names on the command line to
431 prevent the dictionary from being cleared between their
432 executions is no longer supported. All syntax files are now
433 executed as if `+' had been specified.
435 * The -d/--define and -u/--undef command line options are no
436 longer supported. Instead, use /usr/bin/env or shell primitives
437 to define or clear environment variables before invoking PSPP.
439 * If a syntax file named named `rc' is found in a configuration
440 directory (such as $HOME/.pspp), it is executed before any
441 syntax file specified on the command line. The -r or
442 --no-statrc command line option may be used to disable this
447 * Output configuration options have changed. Please refer to the
448 manual for a full description of the available options.
450 In consequence, you will need to reinstall your "devices" file.
451 "make install" will do this for you.
453 * Most error messages are now written to PSPP output files by
454 default. SET ERROR can be used to disable this behavior.
456 * When invoked interactively, PSPP now by default produces output
457 on the terminal, piping it through the "more" program.
458 Previously, by default output was written only to file
459 pspp.list. On most terminals, the page length used for output
460 automatically adapts to the terminal size, even if the terminal
465 - This driver now supports charts in output. Charts are written
466 as separate files that the main output file refers to. By
467 default, charts are written in PNG format to files named
468 pspp-1.png, pspp-2.png, and so on.
470 - Configurations are provided that use VT100 (and xterm)
471 line-drawing characters in tables. The option "-o list-vt100"
472 requests use of this device for output to pspp.list.
476 - The default paper size is now determined using the PAPERSIZE
477 environment variable, or the LC_PAPER locale category on
478 systems that support it. If these are not set, the default is
479 now A4, instead of US letter. To make US letter the default,
480 set PAPERSIZE to "letter" in your environment.
482 - Font metrics are now read from AFM files, instead of
483 Groff-format metrics files. PostScript fonts can now be
486 In consequence, you will need to install an AFM file for each
487 font used in PostScript output. "make install" will install
488 AFM files for the standard PostScript fonts, including the
489 ones that the PostScript driver uses by default.
491 - Standard paper sizes no longer need to be specified through a
492 configuration file. The "papersize" configuration file is no
493 longer needed, or supported.
495 - The PostScript prologue is no longer obtained from the
496 "ps-prologue" configuration file. This configuration file is
497 no longer needed, or supported.
501 - The HTML prologue is no longer obtained from the
502 "html-prologue" configuration file. This configuration file
503 is no longer needed, or supported.
505 Command language changes:
507 * The following commands are new:
509 - GET DATA, which currently supports reading Gnumeric files and
510 text data files. It will be extended later to read other
511 types of foreign data.
513 - CD, to change the current directory.
515 - INSERT, to execute a syntax file.
517 - DELETE VARIABLES, to remove variables from the active file
520 - ADD DOCUMENT, to add text to active file documents.
522 - CLOSE FILE HANDLE (a PSPP extension; see below).
524 - XEXPORT, a PSPP extension that is a transformation equivalent
527 * The following functions for transformation expressions are new:
529 - DATEDIFF, for computing the difference of two dates.
531 - DATESUM, for advancing a date by a specified duration.
533 - VALUELABEL, to obtain the value label for a value.
535 * PSPP now supports very long string variables (over 255 bytes
538 * MATCH FILES now supports the FIRST and LAST subcommands.
540 * Previous versions of PSPP prohibited using commands to both read and
541 write a single file at the same time. Now, PSPP allows this, and
542 the new version of the file atomically replaces the old version.
544 * The following commands are no longer available. They will be
545 re-implemented in a later release:
547 - CLEAR TRANSFORMATIONS
553 * The PROCESS IF command, which was deprecated, has been removed.
554 You may replace any usage of it by SELECT IF following
555 TEMPORARY, which has the same effect.
557 * The output format for variables created by VECTOR may now be
558 specified as part of the VECTOR syntax.
560 "Scratch files", a new PSPP extension:
562 A scratch file, like a system file, consists of a dictionary and
563 any number of cases. Small scratch files are stored in memory;
564 one that grows too large is written to disk. By default, any file
565 handle whose name begins with # is assumed to refer to a scratch
568 Scratch files can be used just about anywhere a system or portable
569 file can be used. Also, portable files are now allowed in most
570 places that system files were allowed in previous PSPP version.
572 A new CLOSE FILE HANDLE command allows the storage associated with
573 scratch files to be freed. It also allows file handles to be
574 reassigned to new files.
576 For more information on scratch files, refer to the "File Handles"
577 section in the PSPP manual. For specifics of what commands now
578 allow what kinds of files to be specified, refer to the
579 documentation on those particular commands.
583 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
584 translation, are now supported. Use FILE HANDLE to specify the
585 format of these files.
587 * Little-endian, big-endian, and VAX-endian formats are now
588 supported for integer binary formats when reading and writing
589 data files. The new RIB and WIB subcommands on the SET command
590 control endianness of integer data. The default is the host's
593 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
594 floating point binary formats when reading and writing data
595 files. The new RRB and WRB subcommands on the SET command
596 control the floating point format. The default is the host's
597 native floating point format.
599 * DATA LIST now supports the SKIP subcommand, to skip records at
600 the beginning of a file. For compatibility, DATA LIST now
601 treats N format as F format for FREE and LIST format input.
603 * The SAVE and XSAVE commands now support the UNSELECTED,
604 PERMISSIONS, NAMES, and MAP subcommands.
606 * The EXPORT command has been re-implemented to obtain better
607 results. Support for the UNSELECTED, DIGITS, and TYPE
608 subcommands has been added.
610 * For compatibility, PRINT now inserts a space at the beginning of
611 every output line, even lines that would otherwise be blank,
612 when OUTFILE is specified. (The behavior of WRITE is
615 * For compatibility, PRINT EJECT now inserts the digit `1' at the
616 beginning of each line that should begin a new page.
618 * For compatibility, WRITE now outputs the system-missing value as
619 a field filled with spaces. Binary formats are an exception.
620 (The behavior of PRINT is unchanged.)
624 * Input and output format descriptions have been rewritten. They
625 now precisely describe what is accepted on input and written on
628 * The descriptions of the PSPP system and portable file formats
629 have been extensively revised and improved.
631 For developers, the build system now requires Autoconf 2.60 and
634 Changes from 0.3.0 to 0.4.0:
636 Changes in build dependencies:
638 * The GNU Scientific Library (libgsl), version 1.6 or later, is
641 * libplot from GNU plotutils is optional. Without it, the new
642 graphing features will not work. If you do not have it
643 installed, you must run `configure' with --without-libplot.
645 * libgmp2 is no longer a dependency.
647 Newly implemented commands and statistical features:
649 * EXAMINE, including its graphing features.
651 * FREQUENCIES now supports percentiles.
659 * SORT CASES now sorts stably, that is, two cases with equal sort
660 criteria will be in the same relative order before and after the
663 * T-TEST (re-written).
665 * DATE and USE. These commands are parsed but otherwise ignored,
666 to enhance compatibility with certain command files that invoke
669 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
670 currently have no effect on PSPP output, but their values are
671 written to and read from system files and thus may affect
672 third-party software.
674 * SET EPOCH implemented.
676 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
679 * FILE HANDLE now supports custom tab widths.
681 Long variable names (and other identifiers) are now supported. Up
682 to the first 64 bytes of each identifier is significant. PSPP now
683 reads and writes system files compatible with SPSS version 12.
685 New --algorithm and --syntax command line options allow
686 SPSS-compatible or enhanced modes to be selected.
688 Support for transformation expressions has been rewritten and
689 significantly improved. Refer to the manual for details.
691 Calculation of moments (mean, standard deviation, kurtosis,
692 skewness) has been rewritten and should now be more accurate. In
693 --algorithm=enhanced mode moments may be more accurate than SPSS in
696 Numerous bugs have been fixed, too many to mention here. Many new
697 tests have been added, leading to the discovery and fixing of many
700 The ASCII output driver can now squeeze multiple blank lines into
703 Much of the code has been rewritten and refactored. It is now much
706 The FILE TYPE and REPEATING DATA commands have been disabled for
707 this release because their implementations were deemed too buggy to
708 be useful. They will be fixed and replaced in a future release.
710 New pspp-mode for Emacs (in pspp-mode.el).
712 Added rudimentary command-line completion for interactive input.
714 lib/julcal and lib/dcdflib are no longer used, so they have been
717 For developers, the build system now requires Autoconf 2.58 and
718 Automake 1.7. The included gettext has been updated to version
721 Some reports state that Texinfo 4.8, the latest version, may be
722 necessary to successfully format the documentation on some systems.
724 Version 0.3.0 changes since 0.2.3:
728 * Using alphanumeric variables in functions under AGGREGATE
731 * Under certain circumstances, the final case would be omitted
732 from the results of an AGGREGATE operation. Fixed.
734 * Undefined behavior was invoked by referencing a freed pointer
735 under certain circumstances. Fixed.
737 * A wrong record size was displayed when paging the active file to
740 * Not having enough temporary space for sorting caused a core
743 * Syntax errors in function descriptions on AGGREGATE caused core
746 * A null pointer was dereferenced, causing a core dump, when
747 PERCENTILES was specified on FREQUENCIES. This fixes the
748 problem, but PSPP still doesn't calculate percentiles.
750 * SORT always sorted in ascending order. Fixed.
752 * Some minor memory leaks in the expression parser were removed.
754 * Many assertions fixed for strict ANSI C compliance.
758 * SET ECHO ON now implemented, but turned off by default.
760 * PRINT specifier supported on END REPEAT.
764 * System libgmp2 library is used if installed instead of
765 unconditionally using the included libgmp2 subset.
767 * Extensive code cleanup, which continues.
769 * Added CORRELATIONS command parser, but not implemented.
771 Version 0.2.3 changes since 0.2.2:
775 * SPLIT FILE with a string variable caused a core dump. Fixed.
777 * Nested INCLUDEs didn't work. Fixed.
779 * The MATCH FILES procedure set the values of variables not present
780 to 0. It should have been SYSMIS. This is now fixed.
782 * The REMARK command was too aggressive about skipping lines. It
783 didn't like being the last command in a file.
785 * Comment parsing wasn't consistent with the rest of the code in its
786 idea of where one command ends and another starts. This meant
787 that sometimes commands would be mysteriously ignored. Thanks to
788 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
790 * The TABLE subcommand on MATCH FILES worked only erratically at
791 best. This fixes it. Thanks to Dr. Dirk Melcher
792 <BZN-mdksh@t-online.de> for reporting this bug.
794 * VARIABLE LABELS rejected a slash before the first variable
795 specification, contradicting the documentation. Thanks to Walter
796 M. Gray <graywm@northernc.on.ca> for reporting this bug.
798 * Because of an incorrect optimization in memory allocation,
799 CROSSTABS sometimes segfaulted when asked to output multiple
800 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
803 * CROSSTABS didn't display value labels for column and row
804 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
807 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
808 <BZN-mdksh@t-online.de> for reporting this bug.
