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 * PSPPIRE graphical user interface improvements:
14 - File|Open now allows an encoding to be selected for opening
17 - File|Display Data File Information|External File... now allows an
18 encoding to be selected.
20 - A problem with the Means dialog has been resolved (bug #41433).
22 - Several problems related to the input of spreadsheets have been
23 fixed (bug #41657, #41620
25 * System file related improvements:
27 - With ENCODING="DETECT", SYSFILE INFO can now help the user to
28 pick an encoding for reading a system file that does not identify
31 - SYSFILE INFO now accepts an ENCODING subcommand to specify the
32 character encoding of string data in the system file.
34 - Variable labels over 255 bytes long are now accepted without
35 truncation (bug #41863).
37 - System files that contain duplicate variable names may now be
38 read successfully (bug #41475).
40 Changes from 0.8.1 to 0.8.2:
42 * Charts are now rendered with colours from the Tango palette instead
43 of fully saturated primaries.
45 * Support for new system file variants:
47 - PSPP can now read and write ZCOMPRESSED system files, which
48 compress data much more effectively than older "compressed"
49 files. (The older format is still supported.)
51 - PSPP can now decrypt encrypted system files, using the new
52 pspp-convert utility. The encrypted system file format is
53 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
54 do not directly read or write this format.
56 * Missing values for long string variables are now read from and
57 written to system files in an SPSS-compatible fashion.
59 (Earlier versions of PSPP that supported missing values for long
60 string variables wrote them to system files in an SPSS-incompatible
61 way. To fix the problem, read the system file with this version of
62 PSPP and then save a new copy of it.)
64 * pspp-convert, a new standalone utility for converting SPSS system
65 and portable files to other formats, is now included. The initial
66 version supports comma-separated value files as output format.
67 pspp-convert can also decrypt encrypted system files.
71 - zlib is now a required dependency. (Previously it was optional.)
73 Changes from 0.8.0 to 0.8.1:
79 * Changes to existing commands:
81 - CROSSTABS: The requirement that one expected count must be less than five
82 before Fishers Exact Test will be reported has been removed.
84 * PSPPIRE graphical user interface improvements:
86 - A new set of icons has been contributed.
88 - Syntax windows now parse syntax in "auto" mode, which in practice
89 should mean that both "batch" and "interactive" syntax now works,
90 instead of just "interactive" syntax.
92 - The variable pane of data windows now include a Role column.
96 - System files written by IBM SPSS 21 are now read without warnings.
98 - System files written by "VOXCO INTERVIEWER 4.3" are now read
101 - PSPPIRE should now more gracefully handle syntax files that contain
104 Changes from 0.6.2 to 0.8.0:
110 - DATAFILE ATTRIBUTES
117 - LOGISTIC REGRESSION
121 - PRESERVE and RESTORE
125 - SAVE TRANSLATE to CSV and tab-delimited files
127 - VARIABLE ATTRIBUTES
129 * Changes to existing commands:
131 - AUTORECODE has a new GROUP subcommand.
133 - CROSSTABS has been re-implemented to fix numerous bugs.
135 - EXAMINE: /MISSING=LISTWISE is now the default.
137 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
138 contains an INCLUDE or INSERT command, substitutions are not
139 applied to the included file.
141 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
143 - HOST has been updated to use more modern syntax.
145 - Most commands that work with data files now support a new
148 - MISSING VALUES can now assign missing values to long string
151 - ONEWAY: the POSTHOC subcommand is now implemented.
153 - The following new subcommands to NPAR TESTS have been implemented:
154 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
155 MCNEMAR, SIGN, WILCOXON, and RUNS
157 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
158 DPROMPT subcommands. The defaults are now fixed values.
160 - SHOW now has a JOURNAL subcommand, to show the location of the
163 - VALUE LABELS can now assign value labels to long string
166 * Other language changes:
168 - The new DATASET commands replace the "scratch file" PSPP
169 extension, which is no longer supported.
171 - Strings may now include arbitrary Unicode code points specified
172 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
173 code point U+1D11E, the musical G clef character, may be
174 expressed as U'1D11E'.
176 See the "Tokens" section in the PSPP manual for more information.
178 - In previous versions of PSPP, in a string expressed in
179 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
180 bytes in the locale encoding. In this version of PSPP, X'hh'
181 syntax always expresses bytes in UTF-8 encoding.
183 See the "Tokens" section in the PSPP manual for more information.
185 * PSPPIRE graphical user interface improvements:
187 - Added support for non-ASCII characters in strings, labels and
190 - A "Split Window" function is available, which makes it easier to
191 see different parts of a large data file.
193 - Data files can now be opened by specifing their name as the first
194 argument. This means that on a properly configured desktop, double
195 clicking on an icon will open the file.
197 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
198 via using an "intelligent" application assistant dialog.
202 - The new "cairo" output driver supports output in PostScript, PDF,
203 and SVG formats. Its functionality is a superset of that of the
204 "postscript" driver, which has been removed. You must have Cairo
205 and Pango installed to build the "cairo" driver.
207 - Charts are now produced with Cairo and Pango, instead of libplot.
208 Without them, the new graphing features will not work. If you do
209 not have Cairo and Pango installed, you must run `configure' with
212 - The plain text output driver now properly supports multibyte UTF-8
213 characters, including double-width characters and combining
216 - Output to OpenDocument format is now supported.
218 - The HTML output is much improved.
220 * The "pspp" program has a new option --batch (or -b) that selects
221 "batch" syntax mode. In previous versions of PSPP this syntax mode
222 was the default. Now a new "auto" syntax mode is the default. In
223 "auto" mode, PSPP interprets most syntax files correctly regardless
224 of their intended syntax mode.
226 See the "Syntax Variants" section in the PSPP manual for more
229 * The "pspp" program has a new option --syntax-encoding that
230 specifies the encoding for syntax files listed on the command line,
231 as well as the default encoding for syntax files included with
232 INCLUDE or INSERT. The default is to accept the system locale
233 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
234 one the system file uses.
236 See the documentation for the INSERT command in the PSPP manual for
239 * Text data files that PRINT and WRITE creates now use the system
240 native line ends by default (CRLF on Windows, LF only elsewhere).
241 Use the new ENDS subcommand on FILE HANDLE to override the default.
243 * A new Perl module allows Perl programs to read and write PSPP
246 * A tutorial chapter has been added to the user manual.
248 Changes from 0.6.1 to 0.6.2:
252 - Dutch, thanks to Harry Thijssen.
254 - Brazilian Portuguese, thanks to Michel Boaventura.
256 Thanks for translations are also due to the coordinators at
257 translationproject.org.
259 * Statistical bug fixes:
261 - REGRESSION: Report correct standard error of the estimate (bug
264 - T-TEST: Report correct significance of paired sample T-test in
265 the common case (bug #26936) and corner cases. Thanks to Mike
266 Griffiths and Matej Cepl for reporting these bugs.
268 * Build fixes and changes:
270 - Fix build with GTK+ 2.17.4 and later.
272 - Make running "make" after running "configure" with different
273 settings reliably rebuild version.c.
275 - Cygwin and MinGW build fixes.
277 - Fixes for building with recent gnulib.
279 - The Makefile now honors two new variables, PSPP_LDFLAGS and
280 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
281 binaries, respectively. This makes building easier for some
284 - Fixes for "configure --enable-relocatable" (bug #25508).
286 * Data file bug fixes and changes:
288 - Fix reading text data files that contain a mix of white space
289 and commas. Now "a ,b" is treated as two fields containing "a"
290 and "b"; previously it was treated as three, with an empty field
293 - Fix writing corrupted .sav files on Windows.
295 - Fix writing variable labels longer than 252 bytes to save files.
296 Thanks to Robert Westlund for reporting this bug.
298 - Fix writing corrupted .por files (bug #26034).
300 - Fix reading .por files whose initial lines are not padded out
301 with spaces as expected.
303 - PSPP will no longer issue warnings about some .sav file records
304 or values that it does not understand. These warnings were
305 harmless, but needlessly alarmed some users.
307 - Fix crash reading empty string fields from PostgreSQL databases.
309 * Bug fixes that affect PSPP and PSPPIRE:
311 - Users may now control precision of output statistics. Instead
312 of hard coding the width and decimals of output numbers, respect
313 the default format in most instances. Counts are now normally
314 displayed with the format of the weight variable, if any.
316 - Fix crash when an INSERT command specifies the name of a file
317 that does not exist (bug #24569).
319 - Fix crash when CROSSTABS specifies a long-string variable (bugs
322 - Fix crash drawing pie charts with many segments.
324 - Fix crash when NUMERIC specifies an invalid format.
326 * PSPPIRE bug fixes and changes:
328 - On Windows, write the output file to the user's home directory
329 instead of the current directory, to better match user
332 - Some data editor fixes.
336 - Fix typo in BINOMIAL section of user manual (bug #25892).
338 Changes from 0.6.0 to 0.6.1:
340 * Statistical bug fixes:
342 - Report correct standardized regression coefficients in linear
343 regression output (bug #23567).
345 * Bug fixes that affect PSPP and PSPPIRE:
347 - Avoid crash with pie charts (bug #24014).
349 - Don't append % to count totals (bug #24003).
351 - Don't crash on bad input (bug #24031).
353 - Don't crash if "end data." is not left aligned (bug #24115).
355 - Change default workspace value to 64 MB, to avoid unnecessary
356 disk accesses on modern machines.
360 - Add ".sav" or ".por" suffix to filename when saving with Save_As
363 - Make it possible to reopen the output window on Windows (bug
366 - A POSIX regular expression library is now included and used
367 automatically if the host does not have one or has one that is
370 * Build fixes and changes:
372 - Work around bug in GSL that prevented build with recent GCC
373 versions without manually adding -fgnu89-inline to CFLAGS.
375 - Also warn about missing prerequisites as we encounter them (bug
378 - Distribute necessary files to allow users working from the
379 distributed tarball to configure with --enable-gui-tools.
381 - Append $(EXEEXT_FOR_BUILD) to output file name when building
382 q2c, fixing build problems on Windows.
384 - GSL 1.8 or later is now required.
386 - Build errors with --enable-relocatable were fixed.
388 * The German translations were removed, since native German speakers
389 found them too poor to be useful.
391 Changes from 0.4.0 to 0.6.0:
393 * The PSPP license is now version 3 or later of the GNU General
394 Public License. Previously, it was version 2 or later.
396 * PSPP now has a graphical interface, called PSPPIRE. This
397 interface allows you to enter data and variable definitions
398 interactively. Commands may be executed in syntax form, or by
399 using the interactive dialog boxes available from the dropdown
402 * A few sample syntax files are now included in the `examples'
405 * Numerous major and minor bugs have been fixed.
409 * The INSTALL file now reflects the details of how to install
410 PSPP. It is a tailored version of the generic installation
411 instructions, instead of a verbatim copy.
413 * iconv, which is ordinarily installed as part of a Unix-like
414 system, is now required. If you don't have it already, you can
415 install GNU libiconv (http://www.gnu.org/software/libiconv/).
417 * libxml2 and zlib are new optional dependencies. They are
418 required to use PSPP's support for reading Gnumeric files.
420 Statistical procedure changes:
422 * REGRESSION is a new procedure for fitting linear models to data
423 via least-squares estimation.
425 * NPAR TESTS is a new procedure for non-parametric tests. In this
426 release, it supports binomial and chi-square tests.
428 * RANK is a new procedure to rank variables. It supports numerous
431 * FREQUENCIES can now output histograms and pie charts. These
432 features were present in earlier releases, but not documented.
434 User interface changes:
436 * In many situations where PSPP once terminated with a fatal
437 error, PSPP now recovers and continues execution.
439 * PSPP is now able to start up and run even if it cannot find its
442 * Journaling of interactive commands to a disk file is now
443 implemented. By default, journaling is enabled, to a file named
444 `pspp.jnl' in the current directory. SET JOURNAL may be used to
447 * The use of `+' between syntax file names on the command line to
448 prevent the dictionary from being cleared between their
449 executions is no longer supported. All syntax files are now
450 executed as if `+' had been specified.
452 * The -d/--define and -u/--undef command line options are no
453 longer supported. Instead, use /usr/bin/env or shell primitives
454 to define or clear environment variables before invoking PSPP.
456 * If a syntax file named named `rc' is found in a configuration
457 directory (such as $HOME/.pspp), it is executed before any
458 syntax file specified on the command line. The -r or
459 --no-statrc command line option may be used to disable this
464 * Output configuration options have changed. Please refer to the
465 manual for a full description of the available options.
467 In consequence, you will need to reinstall your "devices" file.
468 "make install" will do this for you.
470 * Most error messages are now written to PSPP output files by
471 default. SET ERROR can be used to disable this behavior.
473 * When invoked interactively, PSPP now by default produces output
474 on the terminal, piping it through the "more" program.
475 Previously, by default output was written only to file
476 pspp.list. On most terminals, the page length used for output
477 automatically adapts to the terminal size, even if the terminal
482 - This driver now supports charts in output. Charts are written
483 as separate files that the main output file refers to. By
484 default, charts are written in PNG format to files named
485 pspp-1.png, pspp-2.png, and so on.
487 - Configurations are provided that use VT100 (and xterm)
488 line-drawing characters in tables. The option "-o list-vt100"
489 requests use of this device for output to pspp.list.
493 - The default paper size is now determined using the PAPERSIZE
494 environment variable, or the LC_PAPER locale category on
495 systems that support it. If these are not set, the default is
496 now A4, instead of US letter. To make US letter the default,
497 set PAPERSIZE to "letter" in your environment.
499 - Font metrics are now read from AFM files, instead of
500 Groff-format metrics files. PostScript fonts can now be
503 In consequence, you will need to install an AFM file for each
504 font used in PostScript output. "make install" will install
505 AFM files for the standard PostScript fonts, including the
506 ones that the PostScript driver uses by default.
508 - Standard paper sizes no longer need to be specified through a
509 configuration file. The "papersize" configuration file is no
510 longer needed, or supported.
512 - The PostScript prologue is no longer obtained from the
513 "ps-prologue" configuration file. This configuration file is
514 no longer needed, or supported.
518 - The HTML prologue is no longer obtained from the
519 "html-prologue" configuration file. This configuration file
520 is no longer needed, or supported.
522 Command language changes:
524 * The following commands are new:
526 - GET DATA, which currently supports reading Gnumeric files and
527 text data files. It will be extended later to read other
528 types of foreign data.
530 - CD, to change the current directory.
532 - INSERT, to execute a syntax file.
534 - DELETE VARIABLES, to remove variables from the active file
537 - ADD DOCUMENT, to add text to active file documents.
539 - CLOSE FILE HANDLE (a PSPP extension; see below).
541 - XEXPORT, a PSPP extension that is a transformation equivalent
544 * The following functions for transformation expressions are new:
546 - DATEDIFF, for computing the difference of two dates.
548 - DATESUM, for advancing a date by a specified duration.
550 - VALUELABEL, to obtain the value label for a value.
552 * PSPP now supports very long string variables (over 255 bytes
555 * MATCH FILES now supports the FIRST and LAST subcommands.
557 * Previous versions of PSPP prohibited using commands to both read and
558 write a single file at the same time. Now, PSPP allows this, and
559 the new version of the file atomically replaces the old version.
561 * The following commands are no longer available. They will be
562 re-implemented in a later release:
564 - CLEAR TRANSFORMATIONS
570 * The PROCESS IF command, which was deprecated, has been removed.
571 You may replace any usage of it by SELECT IF following
572 TEMPORARY, which has the same effect.
574 * The output format for variables created by VECTOR may now be
575 specified as part of the VECTOR syntax.
577 "Scratch files", a new PSPP extension:
579 A scratch file, like a system file, consists of a dictionary and
580 any number of cases. Small scratch files are stored in memory;
581 one that grows too large is written to disk. By default, any file
582 handle whose name begins with # is assumed to refer to a scratch
585 Scratch files can be used just about anywhere a system or portable
586 file can be used. Also, portable files are now allowed in most
587 places that system files were allowed in previous PSPP version.
589 A new CLOSE FILE HANDLE command allows the storage associated with
590 scratch files to be freed. It also allows file handles to be
591 reassigned to new files.
593 For more information on scratch files, refer to the "File Handles"
594 section in the PSPP manual. For specifics of what commands now
595 allow what kinds of files to be specified, refer to the
596 documentation on those particular commands.
600 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
601 translation, are now supported. Use FILE HANDLE to specify the
602 format of these files.
604 * Little-endian, big-endian, and VAX-endian formats are now
605 supported for integer binary formats when reading and writing
606 data files. The new RIB and WIB subcommands on the SET command
607 control endianness of integer data. The default is the host's
610 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
611 floating point binary formats when reading and writing data
612 files. The new RRB and WRB subcommands on the SET command
613 control the floating point format. The default is the host's
614 native floating point format.
616 * DATA LIST now supports the SKIP subcommand, to skip records at
617 the beginning of a file. For compatibility, DATA LIST now
618 treats N format as F format for FREE and LIST format input.
620 * The SAVE and XSAVE commands now support the UNSELECTED,
621 PERMISSIONS, NAMES, and MAP subcommands.
623 * The EXPORT command has been re-implemented to obtain better
624 results. Support for the UNSELECTED, DIGITS, and TYPE
625 subcommands has been added.
627 * For compatibility, PRINT now inserts a space at the beginning of
628 every output line, even lines that would otherwise be blank,
629 when OUTFILE is specified. (The behavior of WRITE is
632 * For compatibility, PRINT EJECT now inserts the digit `1' at the
633 beginning of each line that should begin a new page.
635 * For compatibility, WRITE now outputs the system-missing value as
636 a field filled with spaces. Binary formats are an exception.
637 (The behavior of PRINT is unchanged.)
641 * Input and output format descriptions have been rewritten. They
642 now precisely describe what is accepted on input and written on
645 * The descriptions of the PSPP system and portable file formats
646 have been extensively revised and improved.
648 For developers, the build system now requires Autoconf 2.60 and
651 Changes from 0.3.0 to 0.4.0:
653 Changes in build dependencies:
655 * The GNU Scientific Library (libgsl), version 1.6 or later, is
658 * libplot from GNU plotutils is optional. Without it, the new
659 graphing features will not work. If you do not have it
660 installed, you must run `configure' with --without-libplot.
662 * libgmp2 is no longer a dependency.
664 Newly implemented commands and statistical features:
666 * EXAMINE, including its graphing features.
668 * FREQUENCIES now supports percentiles.
676 * SORT CASES now sorts stably, that is, two cases with equal sort
677 criteria will be in the same relative order before and after the
680 * T-TEST (re-written).
682 * DATE and USE. These commands are parsed but otherwise ignored,
683 to enhance compatibility with certain command files that invoke
686 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
687 currently have no effect on PSPP output, but their values are
688 written to and read from system files and thus may affect
689 third-party software.
691 * SET EPOCH implemented.
693 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
696 * FILE HANDLE now supports custom tab widths.
698 Long variable names (and other identifiers) are now supported. Up
699 to the first 64 bytes of each identifier is significant. PSPP now
700 reads and writes system files compatible with SPSS version 12.
702 New --algorithm and --syntax command line options allow
703 SPSS-compatible or enhanced modes to be selected.
705 Support for transformation expressions has been rewritten and
706 significantly improved. Refer to the manual for details.
708 Calculation of moments (mean, standard deviation, kurtosis,
709 skewness) has been rewritten and should now be more accurate. In
710 --algorithm=enhanced mode moments may be more accurate than SPSS in
713 Numerous bugs have been fixed, too many to mention here. Many new
714 tests have been added, leading to the discovery and fixing of many
717 The ASCII output driver can now squeeze multiple blank lines into
720 Much of the code has been rewritten and refactored. It is now much
723 The FILE TYPE and REPEATING DATA commands have been disabled for
724 this release because their implementations were deemed too buggy to
725 be useful. They will be fixed and replaced in a future release.
727 New pspp-mode for Emacs (in pspp-mode.el).
729 Added rudimentary command-line completion for interactive input.
731 lib/julcal and lib/dcdflib are no longer used, so they have been
734 For developers, the build system now requires Autoconf 2.58 and
735 Automake 1.7. The included gettext has been updated to version
738 Some reports state that Texinfo 4.8, the latest version, may be
739 necessary to successfully format the documentation on some systems.
741 Version 0.3.0 changes since 0.2.3:
745 * Using alphanumeric variables in functions under AGGREGATE
748 * Under certain circumstances, the final case would be omitted
749 from the results of an AGGREGATE operation. Fixed.
751 * Undefined behavior was invoked by referencing a freed pointer
752 under certain circumstances. Fixed.
754 * A wrong record size was displayed when paging the active file to
757 * Not having enough temporary space for sorting caused a core
760 * Syntax errors in function descriptions on AGGREGATE caused core
763 * A null pointer was dereferenced, causing a core dump, when
764 PERCENTILES was specified on FREQUENCIES. This fixes the
765 problem, but PSPP still doesn't calculate percentiles.
767 * SORT always sorted in ascending order. Fixed.
769 * Some minor memory leaks in the expression parser were removed.
771 * Many assertions fixed for strict ANSI C compliance.
775 * SET ECHO ON now implemented, but turned off by default.
777 * PRINT specifier supported on END REPEAT.
781 * System libgmp2 library is used if installed instead of
782 unconditionally using the included libgmp2 subset.
784 * Extensive code cleanup, which continues.
786 * Added CORRELATIONS command parser, but not implemented.
788 Version 0.2.3 changes since 0.2.2:
792 * SPLIT FILE with a string variable caused a core dump. Fixed.
794 * Nested INCLUDEs didn't work. Fixed.
796 * The MATCH FILES procedure set the values of variables not present
797 to 0. It should have been SYSMIS. This is now fixed.
799 * The REMARK command was too aggressive about skipping lines. It
800 didn't like being the last command in a file.
802 * Comment parsing wasn't consistent with the rest of the code in its
803 idea of where one command ends and another starts. This meant
804 that sometimes commands would be mysteriously ignored. Thanks to
805 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
807 * The TABLE subcommand on MATCH FILES worked only erratically at
808 best. This fixes it. Thanks to Dr. Dirk Melcher
809 <BZN-mdksh@t-online.de> for reporting this bug.
811 * VARIABLE LABELS rejected a slash before the first variable
