6 Please send PSPP bug reports to bug-gnu-pspp@gnu.org.
8 Preliminary list of changes from 0.3.1 to 0.3.2:
10 PSPP now reads and writes system files compatible with spssV12.
12 New commands: VARIABLE WIDTH, VARIABLE ALIGNMENT, VARIABLE LEVEL.
15 Preliminary list of changes from 0.3.0 to 0.3.1:
17 New build dependencies:
19 * The GNU Scientific Library (libgsl), version 1.6 or later.
21 * The GNU multiprecision arithmetic library (libgmp).
23 * libplot from GNU plotutils is optional; without it, the new
24 graphing features will not work.
27 Newly implemented commands and statistical features:
29 * DATE (as a stub, to enhance compatibility).
33 * FREQUENCIES now supports percentiles.
41 * T-TEST (re-written).
43 * USE (as a stub, to enhance compatibility).
45 New --algorithm and --syntax command line options allow
46 SPSS-compatible or enhanced modes to be selected.
48 Support for transformation expressions has been rewritten and
49 significantly improved. Refer to the manual for details.
51 Calculation of moments (mean, standard deviation, kurtosis,
52 skewness) has been rewritten and should now be more accurate.
54 Numerous bugs have been fixed, too many to mention here. Many new
55 tests have been added, leading to the discovery and fixing of many
58 ASCII driver can now squeeze multiple blank lines into single blank
61 Much of the code has been rewritten and refactored. It is now much
64 lib/julcal has been removed.
66 For developers, the build system now requires Autoconf 2.58 and
67 Automake 1.7. The included gettext has been updated to version
70 Version 0.3.0 changes since 0.2.3:
74 * Using alphanumeric variables in functions under AGGREGATE
77 * Under certain circumstances, the final case would be omitted
78 from the results of an AGGREGATE operation. Fixed.
80 * Undefined behavior was invoked by referencing a freed pointer
81 under certain circumstances. Fixed.
83 * A wrong record size was displayed when paging the active file to
86 * Not having enough temporary space for sorting caused a core
89 * Syntax errors in function descriptions on AGGREGATE caused core
92 * A null pointer was dereferenced, causing a core dump, when
93 PERCENTILES was specified on FREQUENCIES. This fixes the
94 problem, but PSPP still doesn't calculate percentiles.
96 * SORT always sorted in ascending order. Fixed.
98 * Some minor memory leaks in the expression parser were removed.
100 * Many assertions fixed for strict ANSI C compliance.
104 * SET ECHO ON now implemented, but turned off by default.
106 * PRINT specifier supported on END REPEAT.
110 * System libgmp2 library is used if installed instead of
111 unconditionally using the included libgmp2 subset.
113 * Extensive code cleanup, which continues.
115 * Added CORRELATIONS command parser, but not implemented.
117 Version 0.2.3 changes since 0.2.2:
121 * SPLIT FILE with a string variable caused a core dump. Fixed.
123 * Nested INCLUDEs didn't work. Fixed.
125 * The MATCH FILES procedure set the values of variables not present
126 to 0. It should have been SYSMIS. This is now fixed.
128 * The REMARK command was too aggressive about skipping lines. It
129 didn't like being the last command in a file.
131 * Comment parsing wasn't consistent with the rest of the code in its
132 idea of where one command ends and another starts. This meant
133 that sometimes commands would be mysteriously ignored. Thanks to
134 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
136 * The TABLE subcommand on MATCH FILES worked only erratically at
137 best. This fixes it. Thanks to Dr. Dirk Melcher
138 <BZN-mdksh@t-online.de> for reporting this bug.
140 * VARIABLE LABELS rejected a slash before the first variable
141 specification, contradicting the documentation. Thanks to Walter
142 M. Gray <graywm@northernc.on.ca> for reporting this bug.
144 * Because of an incorrect optimization in memory allocation,
145 CROSSTABS sometimes segfaulted when asked to output multiple
146 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
149 * CROSSTABS didn't display value labels for column and row
150 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
153 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
154 <BZN-mdksh@t-online.de> for reporting this bug.
156 * The TABLE subcommand on MATCH FILES worked only erratically at
157 best. This fixes it. Thanks to Dr. Dirk Melcher
158 <BZN-mdksh@t-online.de> for reporting this bug.
160 * VARIABLE LABELS rejected a slash before the first variable
161 specification, contradicting the documentation. Thanks to Walter
162 M. Gray <graywm@northernc.on.ca> for reporting this bug.
164 * Because of an incorrect optimization in memory allocation,
165 CROSSTABS sometimes segfaulted when asked to output multiple
166 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
169 * CROSSTABS didn't display value labels for column and row
170 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
173 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
174 <BZN-mdksh@t-online.de> for reporting this bug.
176 * MATCH FILES corrupted memory and dumped core on some syntax
179 * MATCH FILES should set numeric values not available to the
180 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
181 <BZN-mdksh@t-online.de> for reporting this bug.
183 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
184 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
188 * Some systems didn't like the way open_file was coded. Thanks to
189 Hankin <hankin@rogue.consultco.com> for pointing this out.
191 * The SAVE procedure didn't save long string variables properly.
192 Fixed by this patch. Thanks to Hankin
193 <hankin@rogue.consultco.com> for this patch.
195 * Minor documentation fixes for MATCH FILES.
197 Version 0.2.2 changes since 0.2.1:
201 * Fix behavior of PRINT SPACE for negative arguments.
203 * Fix reading some unusual system files.
205 * Fix LIST problems with very long variables. Thanks to Hankin
206 <hankin@dunno.com> for this bug report.
208 * Fix problems with some string format specifiers.
210 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
211 <BZN-mdksh@t-online.de> for reporting this bug.
213 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
214 Hankin <hankin@dunno.com> again on this one.
216 * Sometimes you may encounter a PSPP script that has to be
217 interpreted in interactive mode. Now you can use the -i flag to
220 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
221 `unused variable' warnings under gcc 2.7.2.3, fixing this will
226 * The files in gmp need the internationalization directory in
227 their include path. Thanks to OKUJI Yoshinori
228 <okuji@kuicr.kyoto-u.ac.jp> for pointing this out.
230 Version 0.2.1 changes since 0.2.0:
234 * Remember to include examples/ directory in distribution :-)
236 * Fixed gmp compile problems for some non-i386 architectures.
237 Thanks to Hans Olav Eggestad <olav@jordforsk.nlh.no> and others
240 * DATA LIST FREE and DATA LIST LIST parsing of input files is now
241 matches the documented behavior exactly, and error messages are
242 more helpful. Thanks to Mark H. Wood <mwood@IUPUI.Edu>.
