5 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
9 * Independent T-Tests displayed the standard error of the difference
10 and the confidence interval for the unequal variances case, where
11 the equal variances case should have been. This has been fixed.
13 * REGRESSION now recognises /STATISTICS=CI(x) which causes confidence
14 intervals for the coefficients to be printed.
16 * When DESCRIPTIVES calculates Z scores, it now omits cases filtered
17 by the current FILTER settings.
19 * PSPPIRE graphical user interface improvements:
21 - Dialog boxes with source variable lists can now choose the sort
22 order; right click and select from the popup menu.
24 - File|Open now allows an encoding to be selected for opening
27 - File|Display Data File Information|External File... now allows an
28 encoding to be selected.
30 - A problem with the Means dialog has been resolved (bug #41433).
32 - Several problems related to the input of spreadsheets have been
33 fixed (bug #41657, #41620
35 * System file related improvements:
37 - With ENCODING="DETECT", SYSFILE INFO can now help the user to
38 pick an encoding for reading a system file that does not identify
41 - SYSFILE INFO now accepts an ENCODING subcommand to specify the
42 character encoding of string data in the system file.
44 - Variable labels over 255 bytes long are now accepted without
45 truncation (bug #41863).
47 - System files that contain duplicate variable names may now be
48 read successfully (bug #41475).
50 Changes from 0.8.1 to 0.8.2:
52 * Charts are now rendered with colours from the Tango palette instead
53 of fully saturated primaries.
55 * Support for new system file variants:
57 - PSPP can now read and write ZCOMPRESSED system files, which
58 compress data much more effectively than older "compressed"
59 files. (The older format is still supported.)
61 - PSPP can now decrypt encrypted system files, using the new
62 pspp-convert utility. The encrypted system file format is
63 unacceptably insecure, so to discourage its use PSPP and PSPPIRE
64 do not directly read or write this format.
66 * Missing values for long string variables are now read from and
67 written to system files in an SPSS-compatible fashion.
69 (Earlier versions of PSPP that supported missing values for long
70 string variables wrote them to system files in an SPSS-incompatible
71 way. To fix the problem, read the system file with this version of
72 PSPP and then save a new copy of it.)
74 * pspp-convert, a new standalone utility for converting SPSS system
75 and portable files to other formats, is now included. The initial
76 version supports comma-separated value files as output format.
77 pspp-convert can also decrypt encrypted system files.
81 - zlib is now a required dependency. (Previously it was optional.)
83 Changes from 0.8.0 to 0.8.1:
89 * Changes to existing commands:
91 - CROSSTABS: The requirement that one expected count must be less than five
92 before Fishers Exact Test will be reported has been removed.
94 * PSPPIRE graphical user interface improvements:
96 - A new set of icons has been contributed.
98 - Syntax windows now parse syntax in "auto" mode, which in practice
99 should mean that both "batch" and "interactive" syntax now works,
100 instead of just "interactive" syntax.
102 - The variable pane of data windows now include a Role column.
106 - System files written by IBM SPSS 21 are now read without warnings.
108 - System files written by "VOXCO INTERVIEWER 4.3" are now read
111 - PSPPIRE should now more gracefully handle syntax files that contain
114 Changes from 0.6.2 to 0.8.0:
120 - DATAFILE ATTRIBUTES
127 - LOGISTIC REGRESSION
131 - PRESERVE and RESTORE
135 - SAVE TRANSLATE to CSV and tab-delimited files
137 - VARIABLE ATTRIBUTES
139 * Changes to existing commands:
141 - AUTORECODE has a new GROUP subcommand.
143 - CROSSTABS has been re-implemented to fix numerous bugs.
145 - EXAMINE: /MISSING=LISTWISE is now the default.
147 - DO REPEAT command has been reimplemented. Now, when DO REPEAT
148 contains an INCLUDE or INSERT command, substitutions are not
149 applied to the included file.
151 - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
153 - HOST has been updated to use more modern syntax.
155 - Most commands that work with data files now support a new
158 - MISSING VALUES can now assign missing values to long string
161 - ONEWAY: the POSTHOC subcommand is now implemented.
163 - The following new subcommands to NPAR TESTS have been implemented:
164 COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
165 MCNEMAR, SIGN, WILCOXON, and RUNS
167 - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
168 DPROMPT subcommands. The defaults are now fixed values.
170 - SHOW now has a JOURNAL subcommand, to show the location of the
173 - VALUE LABELS can now assign value labels to long string
176 * Other language changes:
178 - The new DATASET commands replace the "scratch file" PSPP
179 extension, which is no longer supported.
181 - Strings may now include arbitrary Unicode code points specified
182 in hexadecimal, using the syntax U'hhhh'. For example, Unicode
183 code point U+1D11E, the musical G clef character, may be
184 expressed as U'1D11E'.
186 See the "Tokens" section in the PSPP manual for more information.
188 - In previous versions of PSPP, in a string expressed in
189 hexadecimal with X'hh' syntax, the hexadecimal digits expressed
190 bytes in the locale encoding. In this version of PSPP, X'hh'
191 syntax always expresses bytes in UTF-8 encoding.
193 See the "Tokens" section in the PSPP manual for more information.
195 * PSPPIRE graphical user interface improvements:
197 - Added support for non-ASCII characters in strings, labels and
200 - A "Split Window" function is available, which makes it easier to
201 see different parts of a large data file.
203 - Data files can now be opened by specifing their name as the first
204 argument. This means that on a properly configured desktop, double
205 clicking on an icon will open the file.
207 - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
208 via using an "intelligent" application assistant dialog.
212 - The new "cairo" output driver supports output in PostScript, PDF,
213 and SVG formats. Its functionality is a superset of that of the
214 "postscript" driver, which has been removed. You must have Cairo
215 and Pango installed to build the "cairo" driver.
217 - Charts are now produced with Cairo and Pango, instead of libplot.
218 Without them, the new graphing features will not work. If you do
219 not have Cairo and Pango installed, you must run `configure' with
222 - The plain text output driver now properly supports multibyte UTF-8
223 characters, including double-width characters and combining
226 - Output to OpenDocument format is now supported.
228 - The HTML output is much improved.
230 * The "pspp" program has a new option --batch (or -b) that selects
231 "batch" syntax mode. In previous versions of PSPP this syntax mode
232 was the default. Now a new "auto" syntax mode is the default. In
233 "auto" mode, PSPP interprets most syntax files correctly regardless
234 of their intended syntax mode.
236 See the "Syntax Variants" section in the PSPP manual for more
239 * The "pspp" program has a new option --syntax-encoding that
240 specifies the encoding for syntax files listed on the command line,
241 as well as the default encoding for syntax files included with
242 INCLUDE or INSERT. The default is to accept the system locale
243 encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
244 one the system file uses.
246 See the documentation for the INSERT command in the PSPP manual for
249 * Text data files that PRINT and WRITE creates now use the system
250 native line ends by default (CRLF on Windows, LF only elsewhere).
251 Use the new ENDS subcommand on FILE HANDLE to override the default.
253 * A new Perl module allows Perl programs to read and write PSPP
256 * A tutorial chapter has been added to the user manual.
258 Changes from 0.6.1 to 0.6.2:
262 - Dutch, thanks to Harry Thijssen.
264 - Brazilian Portuguese, thanks to Michel Boaventura.
266 Thanks for translations are also due to the coordinators at
267 translationproject.org.
269 * Statistical bug fixes:
271 - REGRESSION: Report correct standard error of the estimate (bug
274 - T-TEST: Report correct significance of paired sample T-test in
275 the common case (bug #26936) and corner cases. Thanks to Mike
276 Griffiths and Matej Cepl for reporting these bugs.
278 * Build fixes and changes:
280 - Fix build with GTK+ 2.17.4 and later.
282 - Make running "make" after running "configure" with different
283 settings reliably rebuild version.c.
285 - Cygwin and MinGW build fixes.
287 - Fixes for building with recent gnulib.
289 - The Makefile now honors two new variables, PSPP_LDFLAGS and
290 PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
291 binaries, respectively. This makes building easier for some
294 - Fixes for "configure --enable-relocatable" (bug #25508).
296 * Data file bug fixes and changes:
298 - Fix reading text data files that contain a mix of white space
299 and commas. Now "a ,b" is treated as two fields containing "a"
300 and "b"; previously it was treated as three, with an empty field
303 - Fix writing corrupted .sav files on Windows.
305 - Fix writing variable labels longer than 252 bytes to save files.
306 Thanks to Robert Westlund for reporting this bug.
308 - Fix writing corrupted .por files (bug #26034).
310 - Fix reading .por files whose initial lines are not padded out
311 with spaces as expected.
313 - PSPP will no longer issue warnings about some .sav file records
314 or values that it does not understand. These warnings were
315 harmless, but needlessly alarmed some users.
317 - Fix crash reading empty string fields from PostgreSQL databases.
319 * Bug fixes that affect PSPP and PSPPIRE:
321 - Users may now control precision of output statistics. Instead
322 of hard coding the width and decimals of output numbers, respect
323 the default format in most instances. Counts are now normally
324 displayed with the format of the weight variable, if any.
326 - Fix crash when an INSERT command specifies the name of a file
327 that does not exist (bug #24569).
329 - Fix crash when CROSSTABS specifies a long-string variable (bugs
332 - Fix crash drawing pie charts with many segments.
334 - Fix crash when NUMERIC specifies an invalid format.
336 * PSPPIRE bug fixes and changes:
338 - On Windows, write the output file to the user's home directory
339 instead of the current directory, to better match user
342 - Some data editor fixes.
346 - Fix typo in BINOMIAL section of user manual (bug #25892).
348 Changes from 0.6.0 to 0.6.1:
350 * Statistical bug fixes:
352 - Report correct standardized regression coefficients in linear
353 regression output (bug #23567).
355 * Bug fixes that affect PSPP and PSPPIRE:
357 - Avoid crash with pie charts (bug #24014).
359 - Don't append % to count totals (bug #24003).
361 - Don't crash on bad input (bug #24031).
363 - Don't crash if "end data." is not left aligned (bug #24115).
365 - Change default workspace value to 64 MB, to avoid unnecessary
366 disk accesses on modern machines.
370 - Add ".sav" or ".por" suffix to filename when saving with Save_As
373 - Make it possible to reopen the output window on Windows (bug
376 - A POSIX regular expression library is now included and used
377 automatically if the host does not have one or has one that is
380 * Build fixes and changes:
382 - Work around bug in GSL that prevented build with recent GCC
383 versions without manually adding -fgnu89-inline to CFLAGS.
385 - Also warn about missing prerequisites as we encounter them (bug
388 - Distribute necessary files to allow users working from the
389 distributed tarball to configure with --enable-gui-tools.
391 - Append $(EXEEXT_FOR_BUILD) to output file name when building
392 q2c, fixing build problems on Windows.
394 - GSL 1.8 or later is now required.
396 - Build errors with --enable-relocatable were fixed.
398 * The German translations were removed, since native German speakers
399 found them too poor to be useful.
401 Changes from 0.4.0 to 0.6.0:
403 * The PSPP license is now version 3 or later of the GNU General
404 Public License. Previously, it was version 2 or later.
406 * PSPP now has a graphical interface, called PSPPIRE. This
407 interface allows you to enter data and variable definitions
408 interactively. Commands may be executed in syntax form, or by
409 using the interactive dialog boxes available from the dropdown
412 * A few sample syntax files are now included in the `examples'
415 * Numerous major and minor bugs have been fixed.
419 * The INSTALL file now reflects the details of how to install
420 PSPP. It is a tailored version of the generic installation
421 instructions, instead of a verbatim copy.
423 * iconv, which is ordinarily installed as part of a Unix-like
424 system, is now required. If you don't have it already, you can
425 install GNU libiconv (http://www.gnu.org/software/libiconv/).
427 * libxml2 and zlib are new optional dependencies. They are
428 required to use PSPP's support for reading Gnumeric files.
430 Statistical procedure changes:
432 * REGRESSION is a new procedure for fitting linear models to data
433 via least-squares estimation.
435 * NPAR TESTS is a new procedure for non-parametric tests. In this
436 release, it supports binomial and chi-square tests.
438 * RANK is a new procedure to rank variables. It supports numerous
441 * FREQUENCIES can now output histograms and pie charts. These
442 features were present in earlier releases, but not documented.
444 User interface changes:
446 * In many situations where PSPP once terminated with a fatal
447 error, PSPP now recovers and continues execution.
449 * PSPP is now able to start up and run even if it cannot find its
452 * Journaling of interactive commands to a disk file is now
453 implemented. By default, journaling is enabled, to a file named
454 `pspp.jnl' in the current directory. SET JOURNAL may be used to
457 * The use of `+' between syntax file names on the command line to
458 prevent the dictionary from being cleared between their
459 executions is no longer supported. All syntax files are now
460 executed as if `+' had been specified.
462 * The -d/--define and -u/--undef command line options are no
463 longer supported. Instead, use /usr/bin/env or shell primitives
464 to define or clear environment variables before invoking PSPP.
466 * If a syntax file named named `rc' is found in a configuration
467 directory (such as $HOME/.pspp), it is executed before any
468 syntax file specified on the command line. The -r or
469 --no-statrc command line option may be used to disable this
474 * Output configuration options have changed. Please refer to the
475 manual for a full description of the available options.
477 In consequence, you will need to reinstall your "devices" file.
478 "make install" will do this for you.
480 * Most error messages are now written to PSPP output files by
481 default. SET ERROR can be used to disable this behavior.
483 * When invoked interactively, PSPP now by default produces output
484 on the terminal, piping it through the "more" program.
485 Previously, by default output was written only to file
486 pspp.list. On most terminals, the page length used for output
487 automatically adapts to the terminal size, even if the terminal
492 - This driver now supports charts in output. Charts are written
493 as separate files that the main output file refers to. By
494 default, charts are written in PNG format to files named
495 pspp-1.png, pspp-2.png, and so on.
497 - Configurations are provided that use VT100 (and xterm)
498 line-drawing characters in tables. The option "-o list-vt100"
499 requests use of this device for output to pspp.list.
503 - The default paper size is now determined using the PAPERSIZE
504 environment variable, or the LC_PAPER locale category on
505 systems that support it. If these are not set, the default is
506 now A4, instead of US letter. To make US letter the default,
507 set PAPERSIZE to "letter" in your environment.
509 - Font metrics are now read from AFM files, instead of
510 Groff-format metrics files. PostScript fonts can now be
513 In consequence, you will need to install an AFM file for each
514 font used in PostScript output. "make install" will install
515 AFM files for the standard PostScript fonts, including the
516 ones that the PostScript driver uses by default.
518 - Standard paper sizes no longer need to be specified through a
519 configuration file. The "papersize" configuration file is no
520 longer needed, or supported.
522 - The PostScript prologue is no longer obtained from the
523 "ps-prologue" configuration file. This configuration file is
524 no longer needed, or supported.
528 - The HTML prologue is no longer obtained from the
529 "html-prologue" configuration file. This configuration file
530 is no longer needed, or supported.
532 Command language changes:
534 * The following commands are new:
536 - GET DATA, which currently supports reading Gnumeric files and
537 text data files. It will be extended later to read other
538 types of foreign data.
540 - CD, to change the current directory.
542 - INSERT, to execute a syntax file.
544 - DELETE VARIABLES, to remove variables from the active file
547 - ADD DOCUMENT, to add text to active file documents.
549 - CLOSE FILE HANDLE (a PSPP extension; see below).
551 - XEXPORT, a PSPP extension that is a transformation equivalent
554 * The following functions for transformation expressions are new:
556 - DATEDIFF, for computing the difference of two dates.
558 - DATESUM, for advancing a date by a specified duration.
560 - VALUELABEL, to obtain the value label for a value.
562 * PSPP now supports very long string variables (over 255 bytes
565 * MATCH FILES now supports the FIRST and LAST subcommands.
567 * Previous versions of PSPP prohibited using commands to both read and
568 write a single file at the same time. Now, PSPP allows this, and
569 the new version of the file atomically replaces the old version.
571 * The following commands are no longer available. They will be
572 re-implemented in a later release:
574 - CLEAR TRANSFORMATIONS
580 * The PROCESS IF command, which was deprecated, has been removed.
581 You may replace any usage of it by SELECT IF following
582 TEMPORARY, which has the same effect.
584 * The output format for variables created by VECTOR may now be
585 specified as part of the VECTOR syntax.
587 "Scratch files", a new PSPP extension:
589 A scratch file, like a system file, consists of a dictionary and
590 any number of cases. Small scratch files are stored in memory;
591 one that grows too large is written to disk. By default, any file
592 handle whose name begins with # is assumed to refer to a scratch
595 Scratch files can be used just about anywhere a system or portable
596 file can be used. Also, portable files are now allowed in most
597 places that system files were allowed in previous PSPP version.
599 A new CLOSE FILE HANDLE command allows the storage associated with
600 scratch files to be freed. It also allows file handles to be
601 reassigned to new files.
603 For more information on scratch files, refer to the "File Handles"
604 section in the PSPP manual. For specifics of what commands now
605 allow what kinds of files to be specified, refer to the
606 documentation on those particular commands.
610 * Binary formats and IBM/360 formats, including ASCII/EBCDIC
611 translation, are now supported. Use FILE HANDLE to specify the
612 format of these files.
614 * Little-endian, big-endian, and VAX-endian formats are now
615 supported for integer binary formats when reading and writing
616 data files. The new RIB and WIB subcommands on the SET command
617 control endianness of integer data. The default is the host's
620 * IEEE 754, VAX, and IBM hexadecimal formats are now supported for
621 floating point binary formats when reading and writing data
622 files. The new RRB and WRB subcommands on the SET command
623 control the floating point format. The default is the host's
624 native floating point format.
626 * DATA LIST now supports the SKIP subcommand, to skip records at
627 the beginning of a file. For compatibility, DATA LIST now
628 treats N format as F format for FREE and LIST format input.
630 * The SAVE and XSAVE commands now support the UNSELECTED,
631 PERMISSIONS, NAMES, and MAP subcommands.
633 * The EXPORT command has been re-implemented to obtain better
634 results. Support for the UNSELECTED, DIGITS, and TYPE
635 subcommands has been added.
637 * For compatibility, PRINT now inserts a space at the beginning of
638 every output line, even lines that would otherwise be blank,
639 when OUTFILE is specified. (The behavior of WRITE is
642 * For compatibility, PRINT EJECT now inserts the digit `1' at the
643 beginning of each line that should begin a new page.
645 * For compatibility, WRITE now outputs the system-missing value as
646 a field filled with spaces. Binary formats are an exception.
647 (The behavior of PRINT is unchanged.)
651 * Input and output format descriptions have been rewritten. They
652 now precisely describe what is accepted on input and written on
655 * The descriptions of the PSPP system and portable file formats
656 have been extensively revised and improved.
658 For developers, the build system now requires Autoconf 2.60 and
661 Changes from 0.3.0 to 0.4.0:
663 Changes in build dependencies:
665 * The GNU Scientific Library (libgsl), version 1.6 or later, is
668 * libplot from GNU plotutils is optional. Without it, the new
669 graphing features will not work. If you do not have it
670 installed, you must run `configure' with --without-libplot.
672 * libgmp2 is no longer a dependency.
674 Newly implemented commands and statistical features:
676 * EXAMINE, including its graphing features.
678 * FREQUENCIES now supports percentiles.
686 * SORT CASES now sorts stably, that is, two cases with equal sort
687 criteria will be in the same relative order before and after the
690 * T-TEST (re-written).
692 * DATE and USE. These commands are parsed but otherwise ignored,
693 to enhance compatibility with certain command files that invoke
696 * VARIABLE WIDTH, VARIABLE ALIGNMENT, and VARIABLE LEVEL. These
697 currently have no effect on PSPP output, but their values are
698 written to and read from system files and thus may affect
699 third-party software.
701 * SET EPOCH implemented.
703 * DATA LIST FREE and DATA LIST LIST now support arbitrary field
706 * FILE HANDLE now supports custom tab widths.
708 Long variable names (and other identifiers) are now supported. Up
709 to the first 64 bytes of each identifier is significant. PSPP now
710 reads and writes system files compatible with SPSS version 12.
712 New --algorithm and --syntax command line options allow
713 SPSS-compatible or enhanced modes to be selected.
715 Support for transformation expressions has been rewritten and
716 significantly improved. Refer to the manual for details.
718 Calculation of moments (mean, standard deviation, kurtosis,
719 skewness) has been rewritten and should now be more accurate. In
720 --algorithm=enhanced mode moments may be more accurate than SPSS in
723 Numerous bugs have been fixed, too many to mention here. Many new
724 tests have been added, leading to the discovery and fixing of many
727 The ASCII output driver can now squeeze multiple blank lines into
730 Much of the code has been rewritten and refactored. It is now much
733 The FILE TYPE and REPEATING DATA commands have been disabled for
734 this release because their implementations were deemed too buggy to
735 be useful. They will be fixed and replaced in a future release.
737 New pspp-mode for Emacs (in pspp-mode.el).
739 Added rudimentary command-line completion for interactive input.
741 lib/julcal and lib/dcdflib are no longer used, so they have been
744 For developers, the build system now requires Autoconf 2.58 and
745 Automake 1.7. The included gettext has been updated to version
748 Some reports state that Texinfo 4.8, the latest version, may be
749 necessary to successfully format the documentation on some systems.
751 Version 0.3.0 changes since 0.2.3:
755 * Using alphanumeric variables in functions under AGGREGATE
758 * Under certain circumstances, the final case would be omitted
759 from the results of an AGGREGATE operation. Fixed.
761 * Undefined behavior was invoked by referencing a freed pointer
762 under certain circumstances. Fixed.
764 * A wrong record size was displayed when paging the active file to
767 * Not having enough temporary space for sorting caused a core
770 * Syntax errors in function descriptions on AGGREGATE caused core
773 * A null pointer was dereferenced, causing a core dump, when
774 PERCENTILES was specified on FREQUENCIES. This fixes the
775 problem, but PSPP still doesn't calculate percentiles.
777 * SORT always sorted in ascending order. Fixed.
779 * Some minor memory leaks in the expression parser were removed.
781 * Many assertions fixed for strict ANSI C compliance.
785 * SET ECHO ON now implemented, but turned off by default.
787 * PRINT specifier supported on END REPEAT.
791 * System libgmp2 library is used if installed instead of
792 unconditionally using the included libgmp2 subset.
794 * Extensive code cleanup, which continues.
796 * Added CORRELATIONS command parser, but not implemented.
798 Version 0.2.3 changes since 0.2.2:
802 * SPLIT FILE with a string variable caused a core dump. Fixed.
804 * Nested INCLUDEs didn't work. Fixed.
806 * The MATCH FILES procedure set the values of variables not present
807 to 0. It should have been SYSMIS. This is now fixed.
809 * The REMARK command was too aggressive about skipping lines. It
810 didn't like being the last command in a file.
812 * Comment parsing wasn't consistent with the rest of the code in its
813 idea of where one command ends and another starts. This meant
