Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
Version 0.3.0 changes since 0.2.3:
Bugs fixed:
* Using alphanumeric variables in functions under AGGREGATE
segfaulted. Fixed.
* Under certain circumstances, the final case would be omitted
from the results of an AGGREGATE operation. Fixed.
* Undefined behavior was invoked by referencing a freed pointer
under certain circumstances. Fixed.
* A wrong record size was displayed when paging the active file to
disk. Fixed.
* Not having enough temporary space for sorting caused a core
dump. Fixed.
* Syntax errors in function descriptions on AGGREGATE caused core
dumps. Fixed.
* A null pointer was dereferenced, causing a core dump, when
PERCENTILES was specified on FREQUENCIES. This fixes the
problem, but PSPP still doesn't calculate percentiles.
* SORT always sorted in ascending order. Fixed.
* Some minor memory leaks in the expression parser were removed.
* Many assertions fixed for strict ANSI C compliance.
New features:
* SET ECHO ON now implemented, but turned off by default.
* PRINT specifier supported on END REPEAT.
Other:
* System libgmp2 library is used if installed instead of
unconditionally using the included libgmp2 subset.
* Extensive code cleanup, which continues.
* Added CORRELATIONS command parser, but not implemented.
Version 0.2.3 changes since 0.2.2:
Bugs fixed:
* SPLIT FILE with a string variable caused a core dump. Fixed.
* Nested INCLUDEs didn't work. Fixed.
* The MATCH FILES procedure set the values of variables not present
to 0. It should have been SYSMIS. This is now fixed.
* The REMARK command was too aggressive about skipping lines. It
didn't like being the last command in a file.
* Comment parsing wasn't consistent with the rest of the code in its
idea of where one command ends and another starts. This meant
that sometimes commands would be mysteriously ignored. Thanks to
Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
* The TABLE subcommand on MATCH FILES worked only erratically at
best. This fixes it. Thanks to Dr. Dirk Melcher
<BZN-mdksh@t-online.de> for reporting this bug.
* VARIABLE LABELS rejected a slash before the first variable
specification, contradicting the documentation. Thanks to Walter
M. Gray <graywm@northernc.on.ca> for reporting this bug.
* Because of an incorrect optimization in memory allocation,
CROSSTABS sometimes segfaulted when asked to output multiple
tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
reporting this bug.
* CROSSTABS didn't display value labels for column and row
variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
reporting this bug.
* WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
<BZN-mdksh@t-online.de> for reporting this bug.

variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
reporting this bug.
* WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
<BZN-mdksh@t-online.de> for reporting this bug.
* MATCH FILES corrupted memory and dumped core on some syntax
errors. Fixed.
* MATCH FILES should set numeric values not available to the
system-missing value, not to 0. Thanks to Dr. Dirk Melcher
<BZN-mdksh@t-online.de> for reporting this bug.
* KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
* Memory leak fix.
* Some systems didn't like the way open_file was coded. Thanks to
Hankin <hankin@rogue.consultco.com> for pointing this out.
* The SAVE procedure didn't save long string variables properly.
Fixed by this patch. Thanks to Hankin
<hankin@rogue.consultco.com> for this patch.
* Minor documentation fixes for MATCH FILES.
Version 0.2.2 changes since 0.2.1:
Bugs fixed:
* Fix behavior of PRINT SPACE for negative arguments.
* Fix reading some unusual system files.
* Fix LIST problems with very long variables. Thanks to Hankin
<hankin@dunno.com> for this bug report.
* Fix problems with some string format specifiers.
* Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
<BZN-mdksh@t-online.de> for reporting this bug.
* Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
Hankin <hankin@dunno.com> again on this one.
* Sometimes you may encounter a PSPP script that has to be
interpreted in interactive mode. Now you can use the -i flag to
do this.
* Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
`unused variable' warnings under gcc 2.7.2.3, fixing this will
take more effort.)
* Tests fixed.
* The files in gmp need the internationalization directory in
their include path. Thanks to OKUJI Yoshinori
<okuji@kuicr.kyoto-u.ac.jp> for pointing this out.
Version 0.2.1 changes since 0.2.0:
Bugs fixed:
* Remember to include examples/ directory in distribution :-)
* Fixed gmp compile problems for some non-i386 architectures.
Thanks to Hans Olav Eggestad <olav@jordforsk.nlh.no> and others
for reporting this.
* DATA LIST FREE and DATA LIST LIST parsing of input files is now
matches the documented behavior exactly, and error messages are
more helpful. Thanks to Mark H. Wood <mwood@IUPUI.Edu>.
Version 0.2.0 changes since 0.1.0:
Procedures now implemented:
* CROSSTABS. Please see documentation for caveats.
Transformations and utilities now implemented:
* AGGREGATE
* APPLY DICTIONARY
* CLEAR TRANSFORMATIONS
* DISPLAY (all subcommands).
* ERASE
* FLIP
* EXPORT
* HOST
* IMPORT
* MATCH FILES
* MATRIX DATA
* NEW FILE
* REPEATING DATA
Support for input and output through pipes: "|command" and
"command|" filenames; support for special filenames "-", "stdin",
"stdout", "stderr".
New command-line features:
* New option --testing-mode: Invoke heuristics to assist testing.
* New option --safer, -s: Don't allow certain unsafe operations.
* New option --command=CMD, -c CMD: Perform literal command CMD.
* rc file ~/.pspp/rc is executed before any other files.
* Now multiple syntax files can be specified.
Operator LAG is now implemented.
Added missing FILE subcommand to REREAD.
Table output manager completely rewritten.
Device configuration file syntax changed. You will need to
reinstall your `devices' file.
New output driver for HTML.
PostScript driver and prologue simplified.
Many bugs fixed. General source-code cleanup.
Added Texinfo documentation for:
* PSPP system file format
* PSPP portable file format
* How to write input for q2c parser generator
* HTML driver
PSPP language is now fully documented. Please report any
inaccuracies or omissions in the documentation.
Changes for version 0.1.0:
First public release. For changes from unreleased development
versions, please see ONEWS.
