8 Version 0.3.1 changes since 0.3.0:
10 Update build system to Autoconf 2.58, Automake 1.7, gettext 0.12.1.
12 Version 0.3.0 changes since 0.2.3:
16 * Using alphanumeric variables in functions under AGGREGATE
19 * Under certain circumstances, the final case would be omitted
20 from the results of an AGGREGATE operation. Fixed.
22 * Undefined behavior was invoked by referencing a freed pointer
23 under certain circumstances. Fixed.
25 * A wrong record size was displayed when paging the active file to
28 * Not having enough temporary space for sorting caused a core
31 * Syntax errors in function descriptions on AGGREGATE caused core
34 * A null pointer was dereferenced, causing a core dump, when
35 PERCENTILES was specified on FREQUENCIES. This fixes the
36 problem, but PSPP still doesn't calculate percentiles.
38 * SORT always sorted in ascending order. Fixed.
40 * Some minor memory leaks in the expression parser were removed.
42 * Many assertions fixed for strict ANSI C compliance.
46 * SET ECHO ON now implemented, but turned off by default.
48 * PRINT specifier supported on END REPEAT.
52 * System libgmp2 library is used if installed instead of
53 unconditionally using the included libgmp2 subset.
55 * Extensive code cleanup, which continues.
57 * Added CORRELATIONS command parser, but not implemented.
59 Version 0.2.3 changes since 0.2.2:
63 * SPLIT FILE with a string variable caused a core dump. Fixed.
65 * Nested INCLUDEs didn't work. Fixed.
67 * The MATCH FILES procedure set the values of variables not present
68 to 0. It should have been SYSMIS. This is now fixed.
70 * The REMARK command was too aggressive about skipping lines. It
71 didn't like being the last command in a file.
73 * Comment parsing wasn't consistent with the rest of the code in its
74 idea of where one command ends and another starts. This meant
75 that sometimes commands would be mysteriously ignored. Thanks to
76 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
78 * The TABLE subcommand on MATCH FILES worked only erratically at
79 best. This fixes it. Thanks to Dr. Dirk Melcher
80 <BZN-mdksh@t-online.de> for reporting this bug.
82 * VARIABLE LABELS rejected a slash before the first variable
83 specification, contradicting the documentation. Thanks to Walter
84 M. Gray <graywm@northernc.on.ca> for reporting this bug.
86 * Because of an incorrect optimization in memory allocation,
87 CROSSTABS sometimes segfaulted when asked to output multiple
88 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
91 * CROSSTABS didn't display value labels for column and row
92 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
95 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
96 <BZN-mdksh@t-online.de> for reporting this bug.
98 * The TABLE subcommand on MATCH FILES worked only erratically at
99 best. This fixes it. Thanks to Dr. Dirk Melcher
100 <BZN-mdksh@t-online.de> for reporting this bug.
102 * VARIABLE LABELS rejected a slash before the first variable
103 specification, contradicting the documentation. Thanks to Walter
104 M. Gray <graywm@northernc.on.ca> for reporting this bug.
106 * Because of an incorrect optimization in memory allocation,
107 CROSSTABS sometimes segfaulted when asked to output multiple
108 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
111 * CROSSTABS didn't display value labels for column and row
112 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
115 * WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
116 <BZN-mdksh@t-online.de> for reporting this bug.
118 * MATCH FILES corrupted memory and dumped core on some syntax
121 * MATCH FILES should set numeric values not available to the
122 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
123 <BZN-mdksh@t-online.de> for reporting this bug.
125 * KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
126 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
130 * Some systems didn't like the way open_file was coded. Thanks to
131 Hankin <hankin@rogue.consultco.com> for pointing this out.
133 * The SAVE procedure didn't save long string variables properly.
134 Fixed by this patch. Thanks to Hankin
135 <hankin@rogue.consultco.com> for this patch.
137 * Minor documentation fixes for MATCH FILES.
139 Version 0.2.2 changes since 0.2.1:
143 * Fix behavior of PRINT SPACE for negative arguments.
145 * Fix reading some unusual system files.
147 * Fix LIST problems with very long variables. Thanks to Hankin
148 <hankin@dunno.com> for this bug report.
150 * Fix problems with some string format specifiers.
152 * Fix use of $CASENUM in expressions. Thanks to Dirk Melcher
153 <BZN-mdksh@t-online.de> for reporting this bug.
155 * Additional DATA LIST FREE and DATA LIST LIST fixes. Thanks to
156 Hankin <hankin@dunno.com> again on this one.
158 * Sometimes you may encounter a PSPP script that has to be
159 interpreted in interactive mode. Now you can use the -i flag to
162 * Warnings for egcs 1.1.1 cleaned up. (However you'll get lots of
163 `unused variable' warnings under gcc 2.7.2.3, fixing this will
168 * The files in gmp need the internationalization directory in
169 their include path. Thanks to OKUJI Yoshinori
170 <okuji@kuicr.kyoto-u.ac.jp> for pointing this out.
172 Version 0.2.1 changes since 0.2.0:
176 * Remember to include examples/ directory in distribution :-)
178 * Fixed gmp compile problems for some non-i386 architectures.
179 Thanks to Hans Olav Eggestad <olav@jordforsk.nlh.no> and others
182 * DATA LIST FREE and DATA LIST LIST parsing of input files is now
183 matches the documented behavior exactly, and error messages are
184 more helpful. Thanks to Mark H. Wood <mwood@IUPUI.Edu>.
186 Version 0.2.0 changes since 0.1.0:
188 Procedures now implemented:
189 * CROSSTABS. Please see documentation for caveats.

217 Operator LAG is now implemented.
219 Added missing FILE subcommand to REREAD.
221 Table output manager completely rewritten.
