| 11:27 | Add --enable-memsys3 and --enable-memsys5 options to the configure script. check-in: 67e1dc98 user: drh tags: trunk | |
| 02:42 | Evidence marks and code reformatting for SQLITE_TRACE_STMT operation. check-in: e1e02238 user: drh tags: trunk | |
| 02:31 | Change SQLITE_TRACE_STMT to return unexpanded SQL text in the X argument. Add documentation on how and when to use sqlite3_expanded_sql(P) to compute the expanded text for legacy sqlite3_trace() compatibility. check-in: 163e1522 user: drh tags: trunk | |
