| 20:46 | In the amalgamation, allocate the parser engine object from stack rather than from heap, for improved performance. This only happens in the amalgamation, since otherwise the sqlite3RunParser() routine does not know the object size. (check-in: 4fe879d4 user: drh tags: trunk) | |

| 01:52 | In the command-line shell, enhance the ".mode" command so that it restores the default column and row separators for modes "line", "list", "column", and "tcl". (check-in: 58f02e6e user: drh tags: trunk) | |
