CLI: For columnar modes ("box", "column", "table", "markdown") the ".width" is now both the minimum and maximum width of the column. Text that spans multiple lines or that contains tabs is properly formatted. If any part of the output contains multi-line text, then extra separators are provided between each row.

Enable SQLITE_INDEX_CONSTRAINT_LIMIT/OFFSET even if there are vector comparison operators in the WHERE clause. Also: Do not enable sqlite3_vtab_rhs_value() for LIMIT/OFFSET if the value is negative, as this violates an invariant on Expr.u.iValue. (check-in: 140480b3 user: drh tags: vtab-limit-offset)

16:47
Remove many redundant checks for sqlite3.mallocFailed now that any OOM should cause Parse.nErr to be non-zero. (check-in: 1f7fa461 user: drh tags: trunk)
15:34
Make it so that any Parse object is always linked into the database conenction while it is active. Hence, an OOM will cause Parse.nErr to be set. (check-in: 6a45d8fe user: drh tags: trunk)
14:01

Add support for the sqlite3_vtab_distinct() interface. Virtual table implementations can use this API to determine more detail about the ordering requirements needed by the query plan and perhaps reduce the amount of work required to compute a correct answer. This is an optimization opportunity for the virtual table implementation. The correct answer should still be obtained (though perhaps more slowly) even if sqlite3_vtab_distinct() is ignored. (check-in: e4caf1e3 user: drh tags: trunk)
20:45

When computing a vector to be used as a key for an index lookup, do not check for NULL values and abort until after all key values have been computed, in case one of the later key values involves some initialization that is needed by a LEFT JOIN.
