Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
+
+Changes since 0.8.4:
-Changes from 0.7.1 to 0.7.2:
+ * 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.
- * Updated Perl module interface.
+ * SYSFILE INFO can now read SPSS/PC+ system files and SPSS portable
+ files.
- * Value labels for long string variables are now supported.
+ * FREQUENCIES: A bug was fixed where an assertion failure occured
+ when an empty dataset was presented.
- * Missing values for long string variables are now supported.
+ * The GRAPH command is now available. Initially it supports
+ scatterplots and histograms.
-Changes from 0.7.0 to 0.7.1:
+Changes from 0.8.3 to 0.8.4:
- * Added a perl module to facilitate reading and writing of pspp system
- files from perl programs.
+ * Formatting of SYSFILE INFO output was made easier to read.
-Changes from 0.6.1 to 0.7.0:
+ * Bug fixes, including the following notable ones:
- * 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.
+ - 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.)
+
+ - 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.
+
+ * Missing values for long string variables are now read from and
+ written to system files in an SPSS-compatible fashion.
+
+ (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.)
+
+ * 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.
+
+ * Build changes:
+
+ - zlib is now a required dependency. (Previously it was optional.)
+
+Changes from 0.8.0 to 0.8.1:
+
+ * New commands:
+
+ - VARIABLE ROLE.
+
+ * Changes to existing commands:
+
+ - CROSSTABS: The requirement that one expected count must be less than five
+ before Fishers Exact Test will be reported has been removed.
+
+ * PSPPIRE graphical user interface improvements:
+
+ - A new set of icons has been contributed.
+
+ - 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.
+
+ - The variable pane of data windows now include a Role column.
+
+ * Notable bug fixes:
+
+ - System files written by IBM SPSS 21 are now read without warnings.
+
+ - System files written by "VOXCO INTERVIEWER 4.3" are now read
+ without warnings.
+
+ - PSPPIRE should now more gracefully handle syntax files that contain
+ errors.
+
+Changes from 0.6.2 to 0.8.0:
+
+ * New commands:
+
+ - 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
+
+ * Changes to existing commands:
+
+ - AUTORECODE has a new GROUP subcommand.
+
+ - CROSSTABS has been re-implemented to fix numerous bugs.
+
+ - EXAMINE: /MISSING=LISTWISE is now the default.
+
+ - 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.
+
+ - HOST has been updated to use more modern syntax.
+
+ - Most commands that work with data files now support a new
+ ENCODING subcommand.
+
+ - MISSING VALUES can now assign missing values to long string
+ variables.
+
+ - ONEWAY: the POSTHOC subcommand is now implemented.
+
+ - The following new subcommands to NPAR TESTS have been implemented:
+ COCHRAN, FRIEDMAN, JONCKHEERE-TERPSTRA, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY,
+ MCNEMAR, SIGN, WILCOXON, and RUNS
+
+ - SET and SHOW no longer have ENDCMD, NULLINE, PROMPT, CPROMPT, and
+ DPROMPT subcommands. The defaults are now fixed values.
+
+ - SHOW now has a JOURNAL subcommand, to show the location of the
+ journal file.
+
+ - 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.
+\f
+Changes from 0.6.1 to 0.6.2:
+
+ * New translations:
+
+ - Dutch, thanks to Harry Thijssen.
+
+ - Brazilian Portuguese, thanks to Michel Boaventura.
+
+ Thanks for translations are also due to the coordinators at
+ translationproject.org.
+
+ * Statistical bug fixes:
+
+ - REGRESSION: Report correct standard error of the estimate (bug
+ #25677).
+
+ - T-TEST: Report correct significance of paired sample T-test in
+ the common case (bug #26936) and corner cases. Thanks to Mike
+ Griffiths and Matej Cepl for reporting these bugs.
+
+ * Build fixes and changes:
+
+ - Fix build with GTK+ 2.17.4 and later.
+
+ - Make running "make" after running "configure" with different
+ settings reliably rebuild version.c.
+
+ - Cygwin and MinGW build fixes.
+
+ - Fixes for building with recent gnulib.
+
+ - The Makefile now honors two new variables, PSPP_LDFLAGS and
+ PSPPIRE_LDFLAGS, that affect linking of the PSPP and PSPPIRE
+ binaries, respectively. This makes building easier for some
+ packagers.
+
+ - Fixes for "configure --enable-relocatable" (bug #25508).
+
+ * Data file bug fixes and changes:
+
+ - Fix reading text data files that contain a mix of white space
+ and commas. Now "a ,b" is treated as two fields containing "a"
+ and "b"; previously it was treated as three, with an empty field
+ in the middle.
+
+ - Fix writing corrupted .sav files on Windows.
+
+ - Fix writing variable labels longer than 252 bytes to save files.
+ Thanks to Robert Westlund for reporting this bug.
+
+ - Fix writing corrupted .por files (bug #26034).
+
+ - Fix reading .por files whose initial lines are not padded out
+ with spaces as expected.
+
+ - PSPP will no longer issue warnings about some .sav file records
+ or values that it does not understand. These warnings were
+ harmless, but needlessly alarmed some users.
+
+ - Fix crash reading empty string fields from PostgreSQL databases.
+
+ * Bug fixes that affect PSPP and PSPPIRE:
+
+ - Users may now control precision of output statistics. Instead
+ of hard coding the width and decimals of output numbers, respect
+ the default format in most instances. Counts are now normally
+ displayed with the format of the weight variable, if any.
+
+ - Fix crash when an INSERT command specifies the name of a file
+ that does not exist (bug #24569).
+
+ - Fix crash when CROSSTABS specifies a long-string variable (bugs
+ #24557 and #26131).
+
+ - Fix crash drawing pie charts with many segments.
+
+ - Fix crash when NUMERIC specifies an invalid format.
+
+ * PSPPIRE bug fixes and changes:
+
+ - On Windows, write the output file to the user's home directory
+ instead of the current directory, to better match user
+ expectations.
+
+ - Some data editor fixes.
+
+ * Documentation:
+
+ - Fix typo in BINOMIAL section of user manual (bug #25892).
