+
+Changes since 0.8.4:
-Changes from 0.7.3 to 0.7.6:
+ * SPSS/PC+ system files are now supported on GET and other commands
+ that read SPSS system files. The pspp-convert program can now read
+ SPSS/PC+ system files. Writing the obsolete SPSS/PC+ system file
+ format is not supported.
- * The "pspp" program has a new option --batch (or -b) that selects
- "batch" syntax mode. In previous versions of PSPP this syntax mode
- was the default. Now a new "auto" syntax mode is the default. In
- "auto" mode, PSPP interprets most syntax files correctly regardless
- of their intended syntax mode.
+ * SYSFILE INFO can now read SPSS/PC+ system files and SPSS portable
+ files.
- See the "Syntax Variants" section in the PSPP manual for more
- information.
+ * FREQUENCIES: A bug was fixed where an assertion failure occured
+ when an empty dataset was presented.
- * The "pspp" program has a new option --syntax-encoding that
- specifies the encoding for syntax files listed on the command line,
- as well as the default encoding for syntax files included with
- INCLUDE or INSERT. The default is to accept the system locale
- encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
- one the system file uses.
+ * The GRAPH command is now available. Initially it supports
+ scatterplots and histograms.
- See the documentation for the INSERT command in the PSPP manual for
- more information.
+Changes from 0.8.3 to 0.8.4:
+
+ * Formatting of SYSFILE INFO output was made easier to read.
+
+ * Bug fixes, including the following notable ones:
+
+ - FREQUENCIES works properly for string variables. (This bug was
+ introduced in 0.8.2.)
+
+ - CROSSTABS now correctly computes all of the measures that it
+ offers. Some measures have been removed because they were not
+ computed correctly.
+
+ - The NPAR TESTS calculation of significance for the RUNS
+ subcommand has been corrected.
+
+ - Planned comparisons in ONEWAY ANOVA now correctly handle negative
+ T-values.
+
+ - Conformance fixes to Open Document output format.
+
+Changes from 0.8.2 to 0.8.3:
+
+ * Independent T-Tests displayed the standard error of the difference
+ and the confidence interval for the unequal variances case, where
+ the equal variances case should have been. This has been fixed.
+
+ * REGRESSION now recognises /STATISTICS=CI(x) which causes confidence
+ intervals for the coefficients to be printed.
+
+ * When DESCRIPTIVES calculates Z scores, it now omits cases filtered
+ by the current FILTER settings.
+
+ * PSPPIRE graphical user interface improvements:
+
+ - Dialog boxes with source variable lists can now choose the sort
+ order; right click and select from the popup menu.
+
+ - File|Open now allows an encoding to be selected for opening
+ system files.
+
+ - File|Display Data File Information|External File... now allows an
+ encoding to be selected.
+
+ - A problem with the Means dialog has been resolved (bug #41433).
+
+ - Several problems related to the input of spreadsheets have been
+ fixed (bug #41657, #41620
+
+ * System file related improvements:
+
+ - With ENCODING="DETECT", SYSFILE INFO can now help the user to
+ pick an encoding for reading a system file that does not identify
+ its own encoding
+
+ - SYSFILE INFO now accepts an ENCODING subcommand to specify the
+ character encoding of string data in the system file.
+
+ - Variable labels over 255 bytes long are now accepted without
+ truncation (bug #41863).
+
+ - System files that contain duplicate variable names may now be
+ read successfully (bug #41475).
+
+Changes from 0.8.1 to 0.8.2:
+
+ * Charts are now rendered with colours from the Tango palette instead
+ of fully saturated primaries.
+
+ * Support for new system file variants:
+
+ - PSPP can now read and write ZCOMPRESSED system files, which
+ compress data much more effectively than older "compressed"
+ files. (The older format is still supported.)
- * The INCLUDE and INSERT commands now support the ENCODING subcommand
- to specify the encoding for the included syntax file.
+ - PSPP can now decrypt encrypted system files, using the new
+ pspp-convert utility. The encrypted system file format is
+ unacceptably insecure, so to discourage its use PSPP and PSPPIRE
+ do not directly read or write this format.
- * Strings may now include arbitrary Unicode code points specified in
- hexadecimal, using the syntax U'hhhh'. For example, Unicode code
- point U+1D11E, the musical G clef character, may be expressed as
- U'1D11E'.
+ * Missing values for long string variables are now read from and
+ written to system files in an SPSS-compatible fashion.
- See the "Tokens" section in the PSPP manual for more information.
+ (Earlier versions of PSPP that supported missing values for long
+ string variables wrote them to system files in an SPSS-incompatible
+ way. To fix the problem, read the system file with this version of
+ PSPP and then save a new copy of it.)
- * In previous versions of PSPP, in a string expressed in hexadecimal
- with X'hh' syntax, the hexadecimal digits expressed bytes in the
- locale encoding. In this version of PSPP, X'hh' syntax always
- expresses bytes in UTF-8 encoding.
+ * pspp-convert, a new standalone utility for converting SPSS system
+ and portable files to other formats, is now included. The initial
+ version supports comma-separated value files as output format.
+ pspp-convert can also decrypt encrypted system files.
- See the "Tokens" section in the PSPP manual for more information.
+ * Build changes:
- * The DO REPEAT command has been reimplemented. The most prominent
- change is that when a DO REPEAT block contains an INCLUDE or INSERT
- command, substitutions are not applied to the included file.
+ - zlib is now a required dependency. (Previously it was optional.)
- See the "DO REPEAT" section in the PSPP manual for more information.
+Changes from 0.8.0 to 0.8.1:
- * NPAR TESTS now supports the /KRUSKAL-WALLIS and /RUNS subcommands.
+ * New commands:
- * AUTORECODE now supports the /GROUP subcommand.
+ - VARIABLE ROLE.
- * The MRSETS command is now implemented.
+ * Changes to existing commands:
- * SAVE TRANSLATE is now implemented, with initial support for saving
- data in comma-separated value and tab-delimited formats.
+ - CROSSTABS: The requirement that one expected count must be less than five
+ before Fishers Exact Test will be reported has been removed.
- * The PRESERVE and RESTORE commands are now implemented.
+ * PSPPIRE graphical user interface improvements:
- * The HOST command has been updated to use more modern syntax.
+ - A new set of icons has been contributed.
- * The SET and SHOW commands no longer support the ENDCMD, NULLINE,
- PROMPT, CPROMPT, and DPROMPT subcommands. The defaults are now the
- only supported values.
+ - Syntax windows now parse syntax in "auto" mode, which in practice
+ should mean that both "batch" and "interactive" syntax now works,
+ instead of just "interactive" syntax.
-Changes from 0.7.2 to 0.7.3:
+ - The variable pane of data windows now include a Role column.
- * Charts are now produced with Cairo and Pango, instead of libplot.
- Without them, the new graphing features will not work. If you do
- not have Cairo and Pango installed, you must run `configure' with
- --without-cairo.
+ * Notable bug fixes:
- * The new "cairo" output driver supports output in PostScript, PDF,
- and SVG formats. Its functionality is a superset of that of the
- "postscript" driver, which has been removed. You must have Cairo
- and Pango installed to build the "cairo" driver.
+ - System files written by IBM SPSS 21 are now read without warnings.
-Changes from 0.7.1 to 0.7.2:
+ - System files written by "VOXCO INTERVIEWER 4.3" are now read
+ without warnings.
- * Updated Perl module interface.
+ - PSPPIRE should now more gracefully handle syntax files that contain
+ errors.
- * Value labels for long string variables are now supported.
+Changes from 0.6.2 to 0.8.0:
- * Missing values for long string variables are now supported.
+ * New commands:
-Changes from 0.7.0 to 0.7.1:
+ - ADD FILES
+ - CORRELATIONS
+ - DATAFILE ATTRIBUTES
+ - DATASET ACTIVATE
+ - DATASET CLOSE
+ - DATASET COPY
+ - DATASET DECLARE
+ - DATASET DISPLAY
+ - DATASET NAME
+ - LOGISTIC REGRESSION
+ - MATCH FILES
+ - MEANS
+ - MRSETS
+ - PRESERVE and RESTORE
+ - QUICK CLUSTER
+ - RELIABILITY
+ - ROC
+ - SAVE TRANSLATE to CSV and tab-delimited files
+ - UPDATE
+ - VARIABLE ATTRIBUTES
- * Added a perl module to facilitate reading and writing of pspp system
- files from perl programs.
+ * Changes to existing commands:
-Changes from 0.6.2-pre6 to 0.7.0:
+ - AUTORECODE has a new GROUP subcommand.
- * Custom variable and data file attributes are now supported.
- Commands VARIABLE ATTRIBUTE and DATAFILE ATTRIBUTE have been added
- for setting and clear attributes. Support for attributes has also
- been added to commands that read and write system files, such as
- SAVE and GET, as well as to the DISPLAY command.
+ - CROSSTABS has been re-implemented to fix numerous bugs.
- * Numererous improvements to the Graphical User Interface have
- made. Notable improvements include:
+ - EXAMINE: /MISSING=LISTWISE is now the default.
- - Non-Ascii characters in strings, labels and variable names are
- now supported.
+ - DO REPEAT command has been reimplemented. Now, when DO REPEAT
+ contains an INCLUDE or INSERT command, substitutions are not
+ applied to the included file.
+
+ - FILE HANDLE has a new ENDS subcommand to select CR or CRLF new-lines.
- - A "Split Window" function is available, which makes it easier to
- see different parts of a large data file.
+ - HOST has been updated to use more modern syntax.
- - Data files can now be opened by specifing their name as the first
- argument. This means that on a properly configured desktop, double
- clicking on an icon will open the file.
-
+ - Most commands that work with data files now support a new
+ ENCODING subcommand.
- * New statistical procedures:
- - CORRELATIONS
- - ROC
- - RELIABILITY
+ - MISSING VALUES can now assign missing values to long string
+ variables.
- NPAR TESTS now supports the WILCOXON and SIGN subcommands.
+ - ONEWAY: the POSTHOC subcommand is now implemented.
- The CROSSTABS command has been completely re-implemented to fix numerous bugs.
+ - The following new subcommands to NPAR TESTS have been implemented:
+ COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
+ MCNEMAR, SIGN, WILCOXON, and RUNS
- * Three new commands to combine data files have been added: MATCH FILES,
- UPDATE and ADD FILES.
+ - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
+ DPROMPT subcommands. The defaults are now fixed values.
- * A tutorial chapter has been added to the user manual.
+ - SHOW now has a JOURNAL subcommand, to show the location of the
+ journal file.
-Changes from 0.6.1 to 0.6.2
+ - VALUE LABELS can now assign value labels to long string
+ variables.
+
+ * Other language changes:
+
+ - The new DATASET commands replace the "scratch file" PSPP
+ extension, which is no longer supported.
+
+ - Strings may now include arbitrary Unicode code points specified
+ in hexadecimal, using the syntax U'hhhh'. For example, Unicode
+ code point U+1D11E, the musical G clef character, may be
+ expressed as U'1D11E'.
+
+ See the "Tokens" section in the PSPP manual for more information.
+
+ - In previous versions of PSPP, in a string expressed in
+ hexadecimal with X'hh' syntax, the hexadecimal digits expressed
+ bytes in the locale encoding. In this version of PSPP, X'hh'
+ syntax always expresses bytes in UTF-8 encoding.
+
+ See the "Tokens" section in the PSPP manual for more information.
+
+ * PSPPIRE graphical user interface improvements:
+
+ - Added support for non-ASCII characters in strings, labels and
+ variable names.
+
+ - A "Split Window" function is available, which makes it easier to
+ see different parts of a large data file.
+
+ - Data files can now be opened by specifing their name as the first
+ argument. This means that on a properly configured desktop, double
+ clicking on an icon will open the file.
+
+ - Foreign formats, such as Gnumeric, OpenDocument and CSV can be imported
+ via using an "intelligent" application assistant dialog.
+
+ * Output changes:
+
+ - The new "cairo" output driver supports output in PostScript, PDF,
+ and SVG formats. Its functionality is a superset of that of the
+ "postscript" driver, which has been removed. You must have Cairo
+ and Pango installed to build the "cairo" driver.
+
+ - Charts are now produced with Cairo and Pango, instead of libplot.
+ Without them, the new graphing features will not work. If you do
+ not have Cairo and Pango installed, you must run `configure' with
+ --without-cairo.
+
+ - The plain text output driver now properly supports multibyte UTF-8
+ characters, including double-width characters and combining
+ accents.
+
+ - Output to OpenDocument format is now supported.
+
+ - The HTML output is much improved.
+
+ * The "pspp" program has a new option --batch (or -b) that selects
+ "batch" syntax mode. In previous versions of PSPP this syntax mode
+ was the default. Now a new "auto" syntax mode is the default. In
+ "auto" mode, PSPP interprets most syntax files correctly regardless
+ of their intended syntax mode.
+
+ See the "Syntax Variants" section in the PSPP manual for more
+ information.
+
+ * The "pspp" program has a new option --syntax-encoding that
+ specifies the encoding for syntax files listed on the command line,
+ as well as the default encoding for syntax files included with
+ INCLUDE or INSERT. The default is to accept the system locale
+ encoding, UTF-8, UTF-16, or UTF-32, automatically detecting which
+ one the system file uses.
+
+ See the documentation for the INSERT command in the PSPP manual for
+ more information.
+
+ * Text data files that PRINT and WRITE creates now use the system
+ native line ends by default (CRLF on Windows, LF only elsewhere).
+ Use the new ENDS subcommand on FILE HANDLE to override the default.
+
+ * A new Perl module allows Perl programs to read and write PSPP
+ system files.
+
+ * A tutorial chapter has been added to the user manual.
