8 Version 0.3.1 changes since 0.3.0:
10 New build dependencies:
12 * The GNU Scientific Library (libgsl), version 1.6 or later.
14 * The GNU multiprecision arithmetic library (libgmp).
16 * libplot from GNU plotutils is optional; without it, the new
17 graphing features will not work.
19 Newly implemented commands and statistical features:
21 * DATE (as a stub, to enhance compatibility).
25 * FREQUENCIES now supports percentiles.
33 * USE (as a stub, to enhance compatibility).
35 New --algorithm and --syntax command line options allow
36 SPSS-compatible or enhanced modes to be selected.
38 Support for transformation expressions has been rewritten and
39 significantly improved. Refer to the manual for details.
41 Calculation of moments (mean, standard deviation, kurtosis,
42 skewness) has been rewritten and should now be more accurate.
44 Numerous bugs have been fixed, too many to mention here. Many new
45 tests have been added, leading to the discovery and fixing of many
48 ASCII driver can now squeeze multiple blank lines into single blank
51 Much of the code has been rewritten and refactored. It is now much
54 For developers, the build system now requires Autoconf 2.58 and
55 Automake 1.7. The included gettext has been updated to version
58 Version 0.3.0 changes since 0.2.3:
62 * Using alphanumeric variables in functions under AGGREGATE
65 * Under certain circumstances, the final case would be omitted
66 from the results of an AGGREGATE operation. Fixed.
68 * Undefined behavior was invoked by referencing a freed pointer
69 under certain circumstances. Fixed.
71 * A wrong record size was displayed when paging the active file to
74 * Not having enough temporary space for sorting caused a core
77 * Syntax errors in function descriptions on AGGREGATE caused core
80 * A null pointer was dereferenced, causing a core dump, when
81 PERCENTILES was specified on FREQUENCIES. This fixes the
82 problem, but PSPP still doesn't calculate percentiles.
84 * SORT always sorted in ascending order. Fixed.
86 * Some minor memory leaks in the expression parser were removed.
88 * Many assertions fixed for strict ANSI C compliance.
92 * SET ECHO ON now implemented, but turned off by default.
94 * PRINT specifier supported on END REPEAT.
98 * System libgmp2 library is used if installed instead of
99 unconditionally using the included libgmp2 subset.
101 * Extensive code cleanup, which continues.
103 * Added CORRELATIONS command parser, but not implemented.
105 Version 0.2.3 changes since 0.2.2:
109 * SPLIT FILE with a string variable caused a core dump. Fixed.
111 * Nested INCLUDEs didn't work. Fixed.
113 * The MATCH FILES procedure set the values of variables not present
114 to 0. It should have been SYSMIS. This is now fixed.
116 * The REMARK command was too aggressive about skipping lines. It
117 didn't like being the last command in a file.
119 * Comment parsing wasn't consistent with the rest of the code in its
120 idea of where one command ends and another starts. This meant
121 that sometimes commands would be mysteriously ignored. Thanks to
122 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
124 * The TABLE subcommand on MATCH FILES worked only erratically at
125 best. This fixes it. Thanks to Dr. Dirk Melcher
126 <BZN-mdksh@t-online.de> for reporting this bug.
128 * VARIABLE LABELS rejected a slash before the first variable
129 specification, contradicting the documentation. Thanks to Walter
130 M. Gray <graywm@northernc.on.ca> for reporting this bug.
132 * Because of an incorrect optimization in memory allocation,
133 CROSSTABS sometimes segfaulted when asked to output multiple
134 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
137 * CROSSTABS didn't display value labels for column and row
138 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
141 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
142 <BZN-mdksh@t-online.de> for reporting this bug.
144 * The TABLE subcommand on MATCH FILES worked only erratically at
145 best. This fixes it. Thanks to Dr. Dirk Melcher
146 <BZN-mdksh@t-online.de> for reporting this bug.
148 * VARIABLE LABELS rejected a slash before the first variable
149 specification, contradicting the documentation. Thanks to Walter
150 M. Gray <graywm@northernc.on.ca> for reporting this bug.
152 * Because of an incorrect optimization in memory allocation,
153 CROSSTABS sometimes segfaulted when asked to output multiple
154 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
157 * CROSSTABS didn't display value labels for column and row
158 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
161 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
162 <BZN-mdksh@t-online.de> for reporting this bug.
164 * MATCH FILES corrupted memory and dumped core on some syntax
167 * MATCH FILES should set numeric values not available to the
168 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
169 <BZN-mdksh@t-online.de> for reporting this bug.
171 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
172 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
176 * Some systems didn't like the way open_file was coded. Thanks to
177 Hankin <hankin@rogue.consultco.com> for pointing this out.
179 * The SAVE procedure didn't save long string variables properly.
180 Fixed by this patch. Thanks to Hankin
181 <hankin@rogue.consultco.com> for this patch.
183 * Minor documentation fixes for MATCH FILES.
185 Version 0.2.2 changes since 0.2.1:
189 * Fix behavior of PRINT SPACE for negative arguments.
191 * Fix reading some unusual system files.
193 * Fix LIST problems with very long variables. Thanks to Hankin
194 <hankin@dunno.com> for this bug report.
196 * Fix problems with some string format specifiers.
198 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
199 <BZN-mdksh@t-online.de> for reporting this bug.
201 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
202 Hankin <hankin@dunno.com> again on this one.
204 * Sometimes you may encounter a PSPP script that has to be
205 interpreted in interactive mode. Now you can use the -i flag to
208 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
209 `unused variable' warnings under gcc 2.7.2.3, fixing this will
214 * The files in gmp need the internationalization directory in
215 their include path. Thanks to OKUJI Yoshinori
216 <okuji@kuicr.kyoto-u.ac.jp> for pointing this out.
218 Version 0.2.1 changes since 0.2.0:
222 * Remember to include examples/ directory in distribution :-)
224 * Fixed gmp compile problems for some non-i386 architectures.
225 Thanks to Hans Olav Eggestad <olav@jordforsk.nlh.no> and others
228 * DATA LIST FREE and DATA LIST LIST parsing of input files is now
229 matches the documented behavior exactly, and error messages are
230 more helpful. Thanks to Mark H. Wood <mwood@IUPUI.Edu>.
232 Version 0.2.0 changes since 0.1.0:
