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 - Dialog boxes with source variable lists can now choose the sort
15 order; right click and select from the popup menu.
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 - A problem with the Means dialog has been resolved (bug #41433).
25 - Several problems related to the input of spreadsheets have been
26 fixed (bug #41657, #41620
28 * System file related improvements:
30 - With ENCODING="DETECT", SYSFILE INFO can now help the user to
31 pick an encoding for reading a system file that does not identify
34 - SYSFILE INFO now accepts an ENCODING subcommand to specify the
35 character encoding of string data in the system file.
37 - Variable labels over 255 bytes long are now accepted without
38 truncation (bug #41863).
40 - System files that contain duplicate variable names may now be
41 read successfully (bug #41475).
43 Changes from 0.8.1 to 0.8.2:
45 * Charts are now rendered with colours from the Tango palette instead
46 of fully saturated primaries.
48 * Support for new system file variants:
50 - PSPP can now read and write ZCOMPRESSED system files, which
51 compress data much more effectively than older "compressed"
52 files. (The older format is still supported.)
54 - PSPP can now decrypt encrypted system files, using the new
55 pspp-convert utility. The encrypted system file format is
56 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
57 do not directly read or write this format.
59 * Missing values for long string variables are now read from and
60 written to system files in an SPSS-compatible fashion.
62 (Earlier versions of PSPP that supported missing values for long
63 string variables wrote them to system files in an SPSS-incompatible
64 way. To fix the problem, read the system file with this version of
65 PSPP and then save a new copy of it.)
67 * pspp-convert, a new standalone utility for converting SPSS system
68 and portable files to other formats, is now included. The initial
69 version supports comma-separated value files as output format.
70 pspp-convert can also decrypt encrypted system files.
74 - zlib is now a required dependency. (Previously it was optional.)
76 Changes from 0.8.0 to 0.8.1:
82 * Changes to existing commands:
84 - CROSSTABS: The requirement that one expected count must be less than five
85 before Fishers Exact Test will be reported has been removed.
87 * PSPPIRE graphical user interface improvements:
89 - A new set of icons has been contributed.
91 - Syntax windows now parse syntax in "auto" mode, which in practice
92 should mean that both "batch" and "interactive" syntax now works,
93 instead of just "interactive" syntax.
95 - The variable pane of data windows now include a Role column.
99 - System files written by IBM SPSS 21 are now read without warnings.
101 - System files written by "VOXCO INTERVIEWER 4.3" are now read
104 - PSPPIRE should now more gracefully handle syntax files that contain
107 Changes from 0.6.2 to 0.8.0:
113 - DATAFILE ATTRIBUTES
120 - LOGISTIC REGRESSION
124 - PRESERVE and RESTORE
128 - SAVE TRANSLATE to CSV and tab-delimited files
130 - VARIABLE ATTRIBUTES
132 * Changes to existing commands:
134 - AUTORECODE has a new GROUP subcommand.
136 - CROSSTABS has been re-implemented to fix numerous bugs.
138 - EXAMINE: /MISSING=LISTWISE is now the default.
140 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
141 contains an INCLUDE or INSERT command, substitutions are not
142 applied to the included file.
144 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
146 - HOST has been updated to use more modern syntax.
148 - Most commands that work with data files now support a new
151 - MISSING VALUES can now assign missing values to long string
154 - ONEWAY: the POSTHOC subcommand is now implemented.
156 - The following new subcommands to NPAR TESTS have been implemented:
157 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
158 MCNEMAR, SIGN, WILCOXON, and RUNS
160 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
161 DPROMPT subcommands. The defaults are now fixed values.
163 - SHOW now has a JOURNAL subcommand, to show the location of the
166 - VALUE LABELS can now assign value labels to long string
169 * Other language changes:
171 - The new DATASET commands replace the "scratch file" PSPP
172 extension, which is no longer supported.
174 - Strings may now include arbitrary Unicode code points specified
175 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
176 code point U+1D11E, the musical G clef character, may be
177 expressed as U'1D11E'.
179 See the "Tokens" section in the PSPP manual for more information.
181 - In previous versions of PSPP, in a string expressed in
182 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
183 bytes in the locale encoding. In this version of PSPP, X'hh'
184 syntax always expresses bytes in UTF-8 encoding.
186 See the "Tokens" section in the PSPP manual for more information.
188 * PSPPIRE graphical user interface improvements:
190 - Added support for non-ASCII characters in strings, labels and
193 - A "Split Window" function is available, which makes it easier to
194 see different parts of a large data file.
196 - Data files can now be opened by specifing their name as the first
197 argument. This means that on a properly configured desktop, double
198 clicking on an icon will open the file.
200 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
201 via using an "intelligent" application assistant dialog.
205 - The new "cairo" output driver supports output in PostScript, PDF,
206 and SVG formats. Its functionality is a superset of that of the
207 "postscript" driver, which has been removed. You must have Cairo
208 and Pango installed to build the "cairo" driver.
210 - Charts are now produced with Cairo and Pango, instead of libplot.
211 Without them, the new graphing features will not work. If you do
212 not have Cairo and Pango installed, you must run `configure' with
215 - The plain text output driver now properly supports multibyte UTF-8
216 characters, including double-width characters and combining
219 - Output to OpenDocument format is now supported.
221 - The HTML output is much improved.
223 * The "pspp" program has a new option --batch (or -b) that selects
224 "batch" syntax mode. In previous versions of PSPP this syntax mode
225 was the default. Now a new "auto" syntax mode is the default. In
226 "auto" mode, PSPP interprets most syntax files correctly regardless
227 of their intended syntax mode.
229 See the "Syntax Variants" section in the PSPP manual for more
232 * The "pspp" program has a new option --syntax-encoding that
233 specifies the encoding for syntax files listed on the command line,
234 as well as the default encoding for syntax files included with
235 INCLUDE or INSERT. The default is to accept the system locale
236 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
237 one the system file uses.
239 See the documentation for the INSERT command in the PSPP manual for
242 * Text data files that PRINT and WRITE creates now use the system
243 native line ends by default (CRLF on Windows, LF only elsewhere).
244 Use the new ENDS subcommand on FILE HANDLE to override the default.
246 * A new Perl module allows Perl programs to read and write PSPP
249 * A tutorial chapter has been added to the user manual.
251 Changes from 0.6.1 to 0.6.2:
255 - Dutch, thanks to Harry Thijssen.
257 - Brazilian Portuguese, thanks to Michel Boaventura.
259 Thanks for translations are also due to the coordinators at
260 translationproject.org.
262 * Statistical bug fixes:
264 - REGRESSION: Report correct standard error of the estimate (bug
267 - T-TEST: Report correct significance of paired sample T-test in
268 the common case (bug #26936) and corner cases. Thanks to Mike
269 Griffiths and Matej Cepl for reporting these bugs.
271 * Build fixes and changes:
273 - Fix build with GTK+ 2.17.4 and later.
275 - Make running "make" after running "configure" with different
276 settings reliably rebuild version.c.
278 - Cygwin and MinGW build fixes.
280 - Fixes for building with recent gnulib.
282 - The Makefile now honors two new variables, PSPP_LDFLAGS and
283 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
284 binaries, respectively. This makes building easier for some
287 - Fixes for "configure --enable-relocatable" (bug #25508).
289 * Data file bug fixes and changes:
291 - Fix reading text data files that contain a mix of white space
292 and commas. Now "a ,b" is treated as two fields containing "a"
293 and "b"; previously it was treated as three, with an empty field
296 - Fix writing corrupted .sav files on Windows.
298 - Fix writing variable labels longer than 252 bytes to save files.
299 Thanks to Robert Westlund for reporting this bug.
301 - Fix writing corrupted .por files (bug #26034).
303 - Fix reading .por files whose initial lines are not padded out
304 with spaces as expected.
306 - PSPP will no longer issue warnings about some .sav file records
307 or values that it does not understand. These warnings were
308 harmless, but needlessly alarmed some users.
310 - Fix crash reading empty string fields from PostgreSQL databases.
312 * Bug fixes that affect PSPP and PSPPIRE:
314 - Users may now control precision of output statistics. Instead
315 of hard coding the width and decimals of output numbers, respect
316 the default format in most instances. Counts are now normally
317 displayed with the format of the weight variable, if any.
319 - Fix crash when an INSERT command specifies the name of a file
320 that does not exist (bug #24569).
322 - Fix crash when CROSSTABS specifies a long-string variable (bugs
325 - Fix crash drawing pie charts with many segments.
327 - Fix crash when NUMERIC specifies an invalid format.
329 * PSPPIRE bug fixes and changes:
331 - On Windows, write the output file to the user's home directory
332 instead of the current directory, to better match user
335 - Some data editor fixes.
339 - Fix typo in BINOMIAL section of user manual (bug #25892).
341 Changes from 0.6.0 to 0.6.1:
343 * Statistical bug fixes:
345 - Report correct standardized regression coefficients in linear
346 regression output (bug #23567).
348 * Bug fixes that affect PSPP and PSPPIRE:
350 - Avoid crash with pie charts (bug #24014).
352 - Don't append % to count totals (bug #24003).
354 - Don't crash on bad input (bug #24031).
356 - Don't crash if "end data." is not left aligned (bug #24115).
358 - Change default workspace value to 64 MB, to avoid unnecessary
359 disk accesses on modern machines.
363 - Add ".sav" or ".por" suffix to filename when saving with Save_As
366 - Make it possible to reopen the output window on Windows (bug
369 - A POSIX regular expression library is now included and used
370 automatically if the host does not have one or has one that is
373 * Build fixes and changes:
375 - Work around bug in GSL that prevented build with recent GCC
376 versions without manually adding -fgnu89-inline to CFLAGS.
378 - Also warn about missing prerequisites as we encounter them (bug
381 - Distribute necessary files to allow users working from the
382 distributed tarball to configure with --enable-gui-tools.
384 - Append $(EXEEXT_FOR_BUILD) to output file name when building
385 q2c, fixing build problems on Windows.
387 - GSL 1.8 or later is now required.
389 - Build errors with --enable-relocatable were fixed.
391 * The German translations were removed, since native German speakers
392 found them too poor to be useful.
394 Changes from 0.4.0 to 0.6.0:
396 * The PSPP license is now version 3 or later of the GNU General
397 Public License. Previously, it was version 2 or later.
399 * PSPP now has a graphical interface, called PSPPIRE. This
400 interface allows you to enter data and variable definitions
401 interactively. Commands may be executed in syntax form, or by
402 using the interactive dialog boxes available from the dropdown
405 * A few sample syntax files are now included in the `examples'
408 * Numerous major and minor bugs have been fixed.
412 * The INSTALL file now reflects the details of how to install
413 PSPP. It is a tailored version of the generic installation
414 instructions, instead of a verbatim copy.
416 * iconv, which is ordinarily installed as part of a Unix-like
417 system, is now required. If you don't have it already, you can
418 install GNU libiconv (http://www.gnu.org/software/libiconv/).
420 * libxml2 and zlib are new optional dependencies. They are
421 required to use PSPP's support for reading Gnumeric files.
423 Statistical procedure changes:
425 * REGRESSION is a new procedure for fitting linear models to data
426 via least-squares estimation.
428 * NPAR TESTS is a new procedure for non-parametric tests. In this
429 release, it supports binomial and chi-square tests.
431 * RANK is a new procedure to rank variables. It supports numerous
434 * FREQUENCIES can now output histograms and pie charts. These
435 features were present in earlier releases, but not documented.
437 User interface changes:
439 * In many situations where PSPP once terminated with a fatal
440 error, PSPP now recovers and continues execution.
442 * PSPP is now able to start up and run even if it cannot find its
445 * Journaling of interactive commands to a disk file is now
446 implemented. By default, journaling is enabled, to a file named
447 `pspp.jnl' in the current directory. SET JOURNAL may be used to
450 * The use of `+' between syntax file names on the command line to
451 prevent the dictionary from being cleared between their
452 executions is no longer supported. All syntax files are now
453 executed as if `+' had been specified.
455 * The -d/--define and -u/--undef command line options are no
456 longer supported. Instead, use /usr/bin/env or shell primitives
457 to define or clear environment variables before invoking PSPP.
459 * If a syntax file named named `rc' is found in a configuration
460 directory (such as $HOME/.pspp), it is executed before any
461 syntax file specified on the command line. The -r or
462 --no-statrc command line option may be used to disable this
467 * Output configuration options have changed. Please refer to the
468 manual for a full description of the available options.
470 In consequence, you will need to reinstall your "devices" file.
471 "make install" will do this for you.
473 * Most error messages are now written to PSPP output files by
474 default. SET ERROR can be used to disable this behavior.
476 * When invoked interactively, PSPP now by default produces output
477 on the terminal, piping it through the "more" program.
478 Previously, by default output was written only to file
479 pspp.list. On most terminals, the page length used for output
480 automatically adapts to the terminal size, even if the terminal
485 - This driver now supports charts in output. Charts are written
486 as separate files that the main output file refers to. By
487 default, charts are written in PNG format to files named
488 pspp-1.png, pspp-2.png, and so on.
490 - Configurations are provided that use VT100 (and xterm)
491 line-drawing characters in tables. The option "-o list-vt100"
492 requests use of this device for output to pspp.list.
496 - The default paper size is now determined using the PAPERSIZE
497 environment variable, or the LC_PAPER locale category on
498 systems that support it. If these are not set, the default is
499 now A4, instead of US letter. To make US letter the default,
500 set PAPERSIZE to "letter" in your environment.
502 - Font metrics are now read from AFM files, instead of
503 Groff-format metrics files. PostScript fonts can now be
506 In consequence, you will need to install an AFM file for each
507 font used in PostScript output. "make install" will install
508 AFM files for the standard PostScript fonts, including the
509 ones that the PostScript driver uses by default.
511 - Standard paper sizes no longer need to be specified through a
512 configuration file. The "papersize" configuration file is no
513 longer needed, or supported.
515 - The PostScript prologue is no longer obtained from the
516 "ps-prologue" configuration file. This configuration file is
517 no longer needed, or supported.
521 - The HTML prologue is no longer obtained from the
522 "html-prologue" configuration file. This configuration file
523 is no longer needed, or supported.
525 Command language changes:
527 * The following commands are new:
529 - GET DATA, which currently supports reading Gnumeric files and
530 text data files. It will be extended later to read other
531 types of foreign data.
533 - CD, to change the current directory.
535 - INSERT, to execute a syntax file.
537 - DELETE VARIABLES, to remove variables from the active file
540 - ADD DOCUMENT, to add text to active file documents.
542 - CLOSE FILE HANDLE (a PSPP extension; see below).
544 - XEXPORT, a PSPP extension that is a transformation equivalent
547 * The following functions for transformation expressions are new:
549 - DATEDIFF, for computing the difference of two dates.
551 - DATESUM, for advancing a date by a specified duration.
553 - VALUELABEL, to obtain the value label for a value.
555 * PSPP now supports very long string variables (over 255 bytes
558 * MATCH FILES now supports the FIRST and LAST subcommands.
560 * Previous versions of PSPP prohibited using commands to both read and
561 write a single file at the same time. Now, PSPP allows this, and
562 the new version of the file atomically replaces the old version.
564 * The following commands are no longer available. They will be
565 re-implemented in a later release:
567 - CLEAR TRANSFORMATIONS
573 * The PROCESS IF command, which was deprecated, has been removed.
574 You may replace any usage of it by SELECT IF following
575 TEMPORARY, which has the same effect.
577 * The output format for variables created by VECTOR may now be
578 specified as part of the VECTOR syntax.
580 "Scratch files", a new PSPP extension:
582 A scratch file, like a system file, consists of a dictionary and
583 any number of cases. Small scratch files are stored in memory;
584 one that grows too large is written to disk. By default, any file
585 handle whose name begins with # is assumed to refer to a scratch
588 Scratch files can be used just about anywhere a system or portable
589 file can be used. Also, portable files are now allowed in most
590 places that system files were allowed in previous PSPP version.
592 A new CLOSE FILE HANDLE command allows the storage associated with
593 scratch files to be freed. It also allows file handles to be
594 reassigned to new files.
596 For more information on scratch files, refer to the "File Handles"
597 section in the PSPP manual. For specifics of what commands now
598 allow what kinds of files to be specified, refer to the
599 documentation on those particular commands.
603 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
604 translation, are now supported. Use FILE HANDLE to specify the
605 format of these files.
607 * Little-endian, big-endian, and VAX-endian formats are now
608 supported for integer binary formats when reading and writing
609 data files. The new RIB and WIB subcommands on the SET command
610 control endianness of integer data. The default is the host's
613 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
614 floating point binary formats when reading and writing data
615 files. The new RRB and WRB subcommands on the SET command
616 control the floating point format. The default is the host's
617 native floating point format.
619 * DATA LIST now supports the SKIP subcommand, to skip records at
620 the beginning of a file. For compatibility, DATA LIST now
621 treats N format as F format for FREE and LIST format input.
623 * The SAVE and XSAVE commands now support the UNSELECTED,
624 PERMISSIONS, NAMES, and MAP subcommands.
626 * The EXPORT command has been re-implemented to obtain better
627 results. Support for the UNSELECTED, DIGITS, and TYPE
628 subcommands has been added.
630 * For compatibility, PRINT now inserts a space at the beginning of
631 every output line, even lines that would otherwise be blank,
632 when OUTFILE is specified. (The behavior of WRITE is
635 * For compatibility, PRINT EJECT now inserts the digit `1' at the
636 beginning of each line that should begin a new page.
638 * For compatibility, WRITE now outputs the system-missing value as
639 a field filled with spaces. Binary formats are an exception.
640 (The behavior of PRINT is unchanged.)
644 * Input and output format descriptions have been rewritten. They
645 now precisely describe what is accepted on input and written on
648 * The descriptions of the PSPP system and portable file formats
649 have been extensively revised and improved.
651 For developers, the build system now requires Autoconf 2.60 and
654 Changes from 0.3.0 to 0.4.0:
656 Changes in build dependencies:
658 * The GNU Scientific Library (libgsl), version 1.6 or later, is
661 * libplot from GNU plotutils is optional. Without it, the new
662 graphing features will not work. If you do not have it
663 installed, you must run `configure' with --without-libplot.
665 * libgmp2 is no longer a dependency.
667 Newly implemented commands and statistical features:
669 * EXAMINE, including its graphing features.
671 * FREQUENCIES now supports percentiles.
679 * SORT CASES now sorts stably, that is, two cases with equal sort
680 criteria will be in the same relative order before and after the
683 * T-TEST (re-written).
685 * DATE and USE. These commands are parsed but otherwise ignored,
686 to enhance compatibility with certain command files that invoke
689 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
690 currently have no effect on PSPP output, but their values are
691 written to and read from system files and thus may affect
692 third-party software.
694 * SET EPOCH implemented.
696 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
699 * FILE HANDLE now supports custom tab widths.
701 Long variable names (and other identifiers) are now supported. Up
702 to the first 64 bytes of each identifier is significant. PSPP now
703 reads and writes system files compatible with SPSS version 12.
705 New --algorithm and --syntax command line options allow
706 SPSS-compatible or enhanced modes to be selected.
708 Support for transformation expressions has been rewritten and
709 significantly improved. Refer to the manual for details.
711 Calculation of moments (mean, standard deviation, kurtosis,
712 skewness) has been rewritten and should now be more accurate. In
713 --algorithm=enhanced mode moments may be more accurate than SPSS in
716 Numerous bugs have been fixed, too many to mention here. Many new
717 tests have been added, leading to the discovery and fixing of many
720 The ASCII output driver can now squeeze multiple blank lines into
723 Much of the code has been rewritten and refactored. It is now much
726 The FILE TYPE and REPEATING DATA commands have been disabled for
727 this release because their implementations were deemed too buggy to
728 be useful. They will be fixed and replaced in a future release.
730 New pspp-mode for Emacs (in pspp-mode.el).
732 Added rudimentary command-line completion for interactive input.
734 lib/julcal and lib/dcdflib are no longer used, so they have been
737 For developers, the build system now requires Autoconf 2.58 and
738 Automake 1.7. The included gettext has been updated to version
741 Some reports state that Texinfo 4.8, the latest version, may be
742 necessary to successfully format the documentation on some systems.
744 Version 0.3.0 changes since 0.2.3:
748 * Using alphanumeric variables in functions under AGGREGATE
751 * Under certain circumstances, the final case would be omitted
752 from the results of an AGGREGATE operation. Fixed.
754 * Undefined behavior was invoked by referencing a freed pointer
755 under certain circumstances. Fixed.
757 * A wrong record size was displayed when paging the active file to
760 * Not having enough temporary space for sorting caused a core
763 * Syntax errors in function descriptions on AGGREGATE caused core
766 * A null pointer was dereferenced, causing a core dump, when
767 PERCENTILES was specified on FREQUENCIES. This fixes the
768 problem, but PSPP still doesn't calculate percentiles.
770 * SORT always sorted in ascending order. Fixed.
772 * Some minor memory leaks in the expression parser were removed.
774 * Many assertions fixed for strict ANSI C compliance.
778 * SET ECHO ON now implemented, but turned off by default.
780 * PRINT specifier supported on END REPEAT.
784 * System libgmp2 library is used if installed instead of
785 unconditionally using the included libgmp2 subset.
787 * Extensive code cleanup, which continues.
789 * Added CORRELATIONS command parser, but not implemented.
791 Version 0.2.3 changes since 0.2.2:
795 * SPLIT FILE with a string variable caused a core dump. Fixed.
797 * Nested INCLUDEs didn't work. Fixed.
799 * The MATCH FILES procedure set the values of variables not present
800 to 0. It should have been SYSMIS. This is now fixed.
802 * The REMARK command was too aggressive about skipping lines. It
803 didn't like being the last command in a file.
805 * Comment parsing wasn't consistent with the rest of the code in its
806 idea of where one command ends and another starts. This meant
807 that sometimes commands would be mysteriously ignored. Thanks to
808 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
810 * The TABLE subcommand on MATCH FILES worked only erratically at
811 best. This fixes it. Thanks to Dr. Dirk Melcher
812 <BZN-mdksh@t-online.de> for reporting this bug.
