| 07:36 | Do not reset the cursor before seeking it in sqlite3BtreeInsert(). This speeds up INSERT operations that use auto-generated rowid values. (CVS 6591) check-in: 20c4acc2 user: danielk1977 tags: trunk | |

| 21:13 | Record within the Token structure itself whether or not the token has been dequoted. This steals one bit from the length of a token and thus limits the size of tokens to 1GiB. (CVS 6589) check-in: 12bcb03d user: drh tags: trunk | |
