+Changes since 0.8.4:
-Changes from 0.6.2 to 0.7.8:
+ * 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.
+
+ * SYSFILE INFO can now read SPSS/PC+ system files and SPSS portable
+ files.
+
+ * FREQUENCIES: A bug was fixed where an assertion failure occured
+ when an empty dataset was presented.
+
+ * The GRAPH command is now available. Initially it supports
+ scatterplots and histograms.
+
+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.)
+
+ - 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:
- DATASET DECLARE
- DATASET DISPLAY
- DATASET NAME
+ - LOGISTIC REGRESSION
- MATCH FILES
- MEANS
- MRSETS
- 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.
- - INCLUDE and INSERT have a new ENCODING subcommand.
+ - 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, KENDALL, KRUSKAL-WALLIS, MANN-WHITNEY, MCNEMAR,
- SIGN, WILCOXON, and RUNS
+ 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.
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,
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.
